From January to June, a company spent $60 per month on office supplies. In July the price of office supplies increased by 15% and remained the same for the rest of the year. How much did the company spend an office supplies for the year
Answer:
$774
Step-by-step explanation:
We have been given that from January to June, a company spent $60 per month on office supplies. In July the price of office supplies increased by 15% and remained the same for the rest of the year.
Let us find increased cost of supplies as shown below:
[tex]\text{Increased cost of supplies}=60+\frac{15}{100}\times 60[/tex]
[tex]\text{Increased cost of supplies}=60+0.15\times 60[/tex]
[tex]\text{Increased cost of supplies}=60+9[/tex]
[tex]\text{Increased cost of supplies}=69[/tex]
There are 6 months from January to June, so cost of supplies on these 6 months would be 6 times $60.
There are 6 months from July to December, so cost of these months would be 6 times $69.
Total cost will be equal to sum of these two amounts.
[tex]\text{Amount spent on office supply in the year}=6\times \$60+6\times \$69[/tex]
[tex]\text{Amount spent on office supply in the year}=6( \$60+\$69)[/tex]
[tex]\text{Amount spent on office supply in the year}=6( \$129)[/tex]
[tex]\text{Amount spent on office supply in the year}=\$774[/tex]
Therefore, $774 were spent on office supplies.
The only types of vehicles sold at a certain dealership last month were sedans, trucks, and vans. If the ratio of the number of sedans to the number of trucks to the number of vans sold at the dealership last month was 4:5:7, respectively, what was the total number of vehicles sold at the dealership last month?1) The number of vans sold at the dealership last month was between 10 and 20.
2) The number of sedans sold at the dealership last month was less than 10.
Answer:
Therefore, 32 is he total number of vehicles sold at the dealership last month.
Step-by-step explanation:
We know that the ratio of the number of sedans to the number of trucks to the number of vans sold at the dealership last month was 4:5:7, respectively. We have :
[tex]4:5:7 \implies 4x+5x+7x=16x[/tex]
Therefore, 16x is he total number of vehicles sold at the dealership last month.
We know that:
1) The number of vans sold at the dealership last month was between 10 and 20.
2) The number of sedans sold at the dealership last month was less than 10
We get:
[tex]10\leq 7x \leq 20\\\implies x=2\\\\\\4x\leq 10\\x=1 \, \vee \, x=2[/tex]
We know that x is a positive integer. In order to satisfy both conditions, this is possible only if x = 2.
We get [tex]16x=16\cdot 2=32[/tex]
Therefore, 32 is he total number of vehicles sold at the dealership last month.

Find the area of the sector and round to the nearest tenth.
Answer:
Step-by-step explanation:
The formula for determining the area of a sector is expressed as
Area = θ/360 × πr²
Where
θ represents the central angle formed by the radii.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
θ = 167 degrees
r = 17.8 yards
Therefore,
Area of sector = 167/360 × 3.14 × 17.8² = 461.5 yards²
The nieces is it a ladder to clean the outside of her second-story windows the lashes is it is 24 feet long and she puts the base of the lead 13 feet away from the house in order to avoid her flower girl that's how high up the side of the house does the Ladder reach
Answer: 20 feet
Step-by-step explanation:
in the attachment
The ladder reaches approximately 19.8 feet up the side of the house, as determined using the Pythagorean theorem.
Explanation:The question is asking us to find the height the ladder reaches up the side of the house. This is a problem dealing with right triangles and can be solved using the Pythagorean theorem, which is a^2 + b^2 = c^2, where 'a' and 'b' are the shorter sides (base and height of the house) and 'c' is the hypotenuse (the ladder).
In this case, the ladder is 24 feet long (this is our c), and the base of the ladder is 13 feet from the house (this is our a). We are trying to find b (the height of the house the ladder reaches).
Substitute these values into the Pythagorean theorem and solve for 'b':
13^2 + b^2 = 24^2
b^2 = 24^2 - 13^2
b = sqrt(24^2 - 13^2)
So, the height that the ladder reaches up the side of the house is approximately 19.8 feet.

A test of intelligence is given to a subject. The subject scores 110 on the first administration. Six months later, the same subject is given the same test again and receives a score of 75. After another six months has passed, the subject is given the test one last time and receives a score of 138. What conclusions can be drawn from these scores?The scores are not valid.
Answer:
True, the scores are not valid.
Step-by-step explanation:
The test supposed to be measuring intelligence. We can assume that the intelligence of most people relatively stable (will not change too much over a short amount of time), and can expect it should go upward with brain growth and education. But the test seems to give a huge decrease from the first and second results. Then the third result is a huge increase that even higher than the first test.
We don't know the true value of the subject, but seeing the huge gap for every repetition we can tell that the test result lacks precision.
use multiplier method to increase £88 by 14%. you must show all your working out
Answer:
£100.32
Step-by-step explanation:
£88 + 14% × £88 = £88×(1 +0.14)
= 1.14×£88
= £100.32 . . . . using a calculator
£100.32 is £88 increased by 14%.
Final answer:
£100.32
Explanation:
To increase an amount by a certain percentage using the multiplier method, you can use the following steps:
Convert the percentage increase to a decimal by dividing by 100. In this case, 14% becomes 0.14.Add 1 to the decimal to get the multiplier. Here, 1 + 0.14 = 1.14.Multiply the original amount by the multiplier. So, £88 multiplied by 1.14 gives us the increased amount.Let's do the calculation:
Step 1: Convert the percentage to a decimal. 14% / 100 = 0.14Step 2: Calculate the multiplier. 1 + 0.14 = 1.14Step 3: Multiply £88 by the multiplier. £88 x 1.14 = £100.32Brenda is building a square fence. She places a fence post at (─3,2). What is the location of the post (in which quadrant) that reflects (─3, 2) across the y-axis?
The location of the reflected post will be in the first quadrant at point (3, 2).
To reflect a point across the y-axis, we simply negate the x-coordinate while keeping the y-coordinate unchanged.
Given the point (-3, 2), when we reflect it across the y-axis, the x-coordinate becomes positive 3, while the y-coordinate remains 2. Therefore, the reflected point is (3, 2).
Since the original point (-3, 2) lies in the second quadrant (negative x, positive y), the reflected point (3, 2) will lie in the first quadrant (positive x, positive y).
Triangle A''B''C'' is formed by a reflection over x=-3 and dilation by a scale factor of 3 from the origin. Which equation shows the correct relationship between ABC and A''B''C'?
Answer: Segments AB / A"B" = √13 / 2 x √13
Step-by-step explanation:
The Triangle's vertices are at points A(-3,3), B(1,-3) and C(-3,-3).
• The reflection over x = 1 shows vertices A, B and C below:
A(-3,3)→A'(5,3);
B(1,-3)→B'(1,3);
C(-3,-3)→C'(5,-3).
• The Dilation by a scale factor of 2 from the origin is expressed as:
(x,y)→(2x,2y)
Therefore,
A'(5,3)→A''(10,6);
B'(1,3)→B''(2,6);
C'(5,-3)→C''(10,-6)

Find the first 3 Iterations of the function here: g(x)=1/3x+1 if you have an initial value of 2.
An example on how to complete it below.
Answer:
1st it: g(2)=1/3(2)+1=0.67+1=1.67
2nd it: g^2(2)=1/3(1.67)+1=0.56+1=1.56
3rd it: g^3(2)=1/3(1.56)+1=0.52+1=1.52
Answer:
The first three iterations are 1.67, 1.56 and 1.52
Step-by-step explanation:
Given the function g(x)=1/3x+1
To get the first threw iteration with initial value of x = 2
First iteration at x= 2:
g(2) = 2/3+1
g(2) = (2+3)/3
g(2) = 5/3 = 1.67
Second iteration will be when x = g(2) = 5/3
g²(2) = g(5/3) = 1/3(5/3) + 1
g²(2) = g(5/3) = 5/9 + 1
g²(2) = g(5/3) = 14/9 = 1.56
Third iteration will be at when
x = g²(2) = 14/9
g³(2) = g(14/9) = 1/3(14/9) + 1
g³(2) = g(14/9) = 14/27 + 1
g³(2) = g(14/9) = 41/27 = 1.52
The first three iterations are 1.67, 1.56 and 1.52
In 2004 the population in Morganton, Georgia, was 43,000. The population in Morganton doubled by 2010. If the growth rate remains the same, what is the expected population in Morganton in 2020?
Answer:
263,606.9
Step-by-step explanation:
In 2004 the population in Morganton, Georgia, was 43,000.
(0, 43000)
The population in Morganton doubled by 2010
In 6 years the population is doubled (86000)

A Cepheid variable star is a star whose brightness alternately increases and decreases. Suppose that Cephei Joe is a star for which the interval between times of maximum brightness is 6.6 days. Its average brightness is 2.6 and the brightness changes by /-0.6. Using this data, we can construct a mathematical model for the brightness of Cephei Joe at time t, where t is measured in days:
(a) Find the rate of change of the brightness after t days.
(b) Find the rate of increase after one day.
Answer:
a) Rate of brightness after t days = B(t) = 2.6 + 0.6sin(2×3.142 t /6.6)
b) 0.57
Step-by-step explanation:
Given
Number of days=6,6 days
Average brightness =2.6
B(t)= 2.6 + 0.6 sin (2× 3.142t/6.6)
b) B(1day) = 0.6 ×(2×3.142/6.6)cos (2×3.142/6.6)
B(1 day) = 0.6 × (6.248/6.6)cos 0.952
B(1 day) =0.6 × 0.952 ×0.9999
B(1day) = 0.5711

Do people who work for non-profit organizations differ from those who work at for-profit companies when it comes to personal job satisfaction? Separate random samples were collected by a polling agency to investigate the difference. Data collected from 422 employees at non-profit organizations revealed that 377 of them were "highly satisfied." From the for-profit companies, 431 out 518 employees reported the same level of satisfaction. Find the standard error of the difference in sample proportions.
Answer:
0.0223
Step-by-step explanation:
Given the following data x(1) = 377, n(1) = 422, x(2) = 431, n(2) = 518
The sample proportion is the number of success divided by the sample.
P(1) = x(1)/n(1) = 377/422 = 0.8934
P(2) = x(2)/n(2) = 431/518 = 0.8320
Formular for the standard error of the difference in sample proportions
S.E = √p(1)q(1)/n(1)+P(2)q(2)/n(2)
S.E = √p1(1-P1)/n1+P2(1-P2)/n2
By substitution we have that,
S.E = √0.8934(1-0.8934)/422+0.8320(1-0.8320)/518
S.E = 0.0223

The perimeter of a rectangular note card is 18 inches. The area is 18 square inches. What are the dimensions of the note card?
Answer:
6 by 3
Step-by-step explanation:
a rectangle as 2 equal sides. so if we know that it is 6 by 3, then 6+6+3+3
=12+6=18
the area of a rectangle is base * height. so 6 * 3 = 18
Answer: the length is 6 inches and the width is 3 inches.
Step-by-step explanation:
Let L represent the length of the rectangular note card.
Let W represent the width of the rectangular note card.
The formula for determining the area of a rectangle is expressed as
Area = L × W
Area of the note card would be
LW = 18 - - - - - - - - - - - - 1
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
Perimeter of the note card would be
2(L + W) = 18
(L + W) = 9 - - - - - - - - - - - - 2
Substituting L = 9 - W into equation 1, it becomes
W(9 - W) = 18
9W - W² = 18
W² - 9W + 18 = 0
W² - 6W - 3W + 18 = 0
W(W - 6) - 3(W - 6) = 0
W - 6 = 0 or W - 3 = 0
W = 6 or W = 3
Substituting W = 3 into equation 1, it becomes
3L = 18
L = 18/3 = 6
For a given geometric sequence, the 4th term, a4, is equal to 19625, and the 9th term, a9, is equal to −95. Find the value of the 13th term? a 13 If applicable, write your answer as a fraction.
Answer:
The value of the [tex]13^{th}[/tex] term is ≈ 1.
Step-by-step explanation:
A geometric sequence is a series of numbers where each term is computed by multiplying the previous term by a constant, r also known as the common ratio.
The formula to compute the [tex]n^{th}[/tex] term of a GP is: [tex]a_{n}=a_{1}\times r^{n-1}[/tex]
Here, a₁ is the first term.
It is provided that a₄ = 19625 and a₉ = 95.
Determine the value of a₁ and r as follows:
[tex]\frac{a_{4}}{a_{9}}=\frac{a_{1}r^{4-1}}{a_{1}r^{9-1}} \\\frac{19625}{95}= \frac{r^{3}}{r^{8}}r^{5}=\frac{95}{19625}\\ r=(\frac{95}{19625})^{1/5}\\=0.344[/tex]
The common ratio is, r = 0.344.
The value of a₁ is:
[tex]a_{4}=19625\\a_{1}\times(0.344)^{3}=19625\\a_{1}=\frac{19625}{0.040707584} \\=482096.898\\\approx482097[/tex]
The first term is, a₁ = 482097.
13th term of this geometric sequence is:
[tex]a_{13}=a_{1}\times r^{13-1}\\=482097\times (0.344)^{12}\\=1.3234\\\approx1[/tex]
Thus, the [tex]13^{th}[/tex] term is approximately equal to 1.

Step-by-step explanation:
The volume of the box = 13 x 8 x 4 = 416 cubic unit
The volume of the brick with the dimensions = 18 cubic unit
Now as per the question, we want to fill an empty box with 416 cubic unit with the help of bricks which are 18 cubic unit each.
The maximum number of bricks required to fill the box = Volume of the box ÷ Volume of one brick.
→ The number of bricks required to fill the box = 416 ÷ 18 = 23.11
But, number of bricks can never be in fraction so it means a maximum of 23 bricks can accommodate in the given box. We will not choose 24 or more than 24 bricks because these much bricks will go out of the dimensions.
Note: Volume of a cuboid = length x breadth x height (l x b x h).
To solve the problem, you divide each dimension of the box by the corresponding dimension of the brick, rounding down to the nearest whole number to get the number of bricks that can fit in each direction. You then multiply these together to get the total. In this case, a maximum of 16 bricks can fit.
Explanation:The problem at hand requires spatial reasoning and division. The challenge is to determine how many 'bricks' (which we'll engage as 3x3x2 units) can fit into a larger 'box' (which is 13x8x4 units). This can be determined by individually dividing the dimensions of the box by the dimensions of the brick.
For instance, considering the length, we divide 13 by 3 to get approximately 4.33. Considering that we can't fractionate a brick, we can place only 4 bricks along the length. Using the same approach, we divide 8 by 3 for the width to get approximately 2.67, and we can place 2 bricks here. It's the same for the height; 4 divided by 2 is 2. Therefore, we can place 2 bricks along the height.
To get the total number of bricks that can fit in the box, multiply the numbers together: 4 (length) x 2 (width) x 2 (height), giving a result of 16 bricks. Hence, a maximum of 16 bricks of size 3x3x2 can fit into a box of size 13x8x4 without going out of the box or overlapping.

X minus 12 is 30 what’s the answer
Answer:
x=42
Step-by-step explanation:
x-12=30
x=30+12
x=42
To solve for x in this equation, we want to get x by itself on the left side of the equation. Since 12 is being subtracted from x, to get x by itself, we need to add 12 to the left side of the equation. If we add 12 to the left side, we must also add 12 to the right side.
On the left side, -12 and +12 cancel each other out so we are simply left with x. On the right side, 30 + 12 is 42 so we have x = 42.
It's important to understand that we can check our answer by substituting 42 back into the original equation.
So we have (42) - 12 = 30.
42 - 12 is 30 so we have 30 = 30 which is a true statement so our answer, x = 42, is correct.

Answer: 6x^13-1.5w+156x+13 is the answer to the first equation and is that another equation?
The expression 13 - 0.5w + 6x evaluates to 11 when substituting w=10 and x=1/2.
Explanation:The problem is to evaluate the expression 13 - 0.5w + 6x given the values w=10 and x=1/2. Following the order of operations, we first substitute the given values into the expression.
13 - 0.5(10) + 6(1/2) = 13 - 5 + 3 = 11.
The result of the evaluated expression is 11.
An inelastic collision occurs between a large truck and smaller sedan. Calculate the final velocity of the objects and explain the direction they will be traveling with the following data from before the collision: Small sedan mass = 1300 kg initial velocity = 20 m/s Truck mass = 7100 kg Initial Velocity 15 m/s
The final velocity is 15.8 m/s in the forward direction
Step-by-step explanation:
An inelastic collision occurs when the two object after the collision stick together.
In any case, the total momentum of the system is conserved before and after the collision, in absence of external forces. Therefore, we can write:
[tex]p_i = p_f\\m u + MU = (m+M)v[/tex]
where in this problem:
m = 1300 kg is the mass of the small sedan
u = 20 m/s is the initial velocity of the small sedan
M = 7100 kg is the mass of the truck
U = 15 m/s is the initial velocity of the truck
v is the final combined velocity of the small sedan + truck
Here we have taken both the velocity of the sedan and the truck in the positive (forward) direction
Solving the equation for v, we find the final velocity:
[tex]v=\frac{mu+MU}{m+M}=\frac{(1300)(20)+(7100)(15)}{1300+7100}=15.8 m/s[/tex]
And since the sign is positive, this means that is direction is the same as the initial direction of the sedan and the truck, so forward.
