Answer:
-1.777...
Step-by-step explanation:
Using the LCM of 18 for the denominator, these values are:
-1 7/9 -1 1/2
-32/18 -27/18 0
--------------|-------------------|-------------------------------------|-----------
So, the easy values to identify are: -31/18, -30/18, -29/18, and -28/18
All of these numbers have repeating decimals (because 9 is a factor of the denominator).
Now, you may realize that -1 3/4 is within the range specified.
-1 7/9 -1 1/2
-32/18 -27/18 0
--------------|-------------------|-------------------------------------|-----------

Two weeks in a row, the golf course hosts a group of golfers. The second week had 10 more golfers than the first week. Use the dot plots to choose the true statement.
A. The range for Week 1 equals the range for Week 2.
B. The range for Week 1 is greater than the range for Week 2.
C. The median for Week 1 is less than the median for Week 2.
D. The mean for Week 1 is greater than the mean for Week 2.
Answer:
The true statement is: A. The range for Week 1 equals the range for Week 2.
Step-by-step explanation:
Let's recall that the range of a data set is the difference between the largest number and the smallest number.
As we can confirm in the plot for week 1, the range is:
Range for week 1 = Largest number - smallest number
Range for week 1 = 89 - 62 = 27
In the same way, we can confirm in the plot for week 2 that the range is:
Range for week 2 = Largest number - smallest number
Range for week 2 = 89 - 62 = 27
Ranges for week 1 and 2 are equal, thus,
The true statement is: A. The range for Week 1 equals the range for Week 2.

the sum of the 5th term of the 7th term of an ap is 52 and the 10th term is 46 find the AP
Answer:
The AP is, 1 , 6, 11, 16, 21, 26, 31, .....................
Step-by-step explanation:
From the question;
Sum of fifth term and 7th term is 52 That is; 5th term + 7th term = 5210th term is 46We are required to find the AP;
We need to know that in an AP ;nth term = a + (n-1) d , where a is the first term and d is the common difference
Therefore, In this case;5th term = a + 4d
7th term = a + 6d
Therefore;5th term + 7th term = 2a + 10d = 52 ..........eqn 1
10th term = a + 9d
Thus, a + 9d = 46 ............. eqn 2We can solve eqn 1 and eqn 2 simultaneously to get the value of a and d2a + 10d = 52
a + 9d = 46
Multiplying the second equation by 2, we get;
2a + 10d = 52
2a + 18d = 92
Eliminating a by subtracting the two equations; we get;
-8d = -40
d = 5
Solving for a
a + 9d = 46
a = 46 - 9d
= 46 - 9(5)
= 46 - 45
a = 1
Thus, the first term, a= 1 and the common difference, d= 5
Therefore;
First term = a = 1
Second term = a + d = 1 + 5 = 6
Third term = a + 2d = 1 + 2(5) = 11
Fourth term = a + 3d = 1 + 3(5) =16
Fifth term = a + 4d = 1 + 4(5) = 21
Sixth term = 1 + 5d = 1 + 5(5) = 26
Seventh term = 1 + 6d = 1 + 6(5) = 31
Thus,
The AP is, 1 , 6, 11, 16, 21, 26, 31, .....................
25. Belle had the choice of taking out a 4-year car loan at
8.5% simple interest or a 5-year car loan at 7.75%
simple interest. If she borrows $15,000, how much
interest would she pay for each loan? Which option
will require less interest?
Answer:
the first loan is cheaper
Step-by-step explanation:
convert percent values to decimals
8.5/100=.085
7.75/100=.0775
find the value for the first loan
1550*.085*4=527
find the value for the first loan
1550*.0775*5=600.625
compare
Belle would pay $5100 in interest for the 4-year loan at 8.5% and $5812.50 for the 5-year loan at 7.75%. Therefore, less interest would be paid with the 4-year loan.
Explanation:To calculate the simple interest, we use the formula I = P*R*T, where P is the principal amount, R is the interest rate, and T is the time in years.
For the 4-year loan at 8.5%, interest would be: I = $15,000 * 8.5/100 * 4 = $5100
For the 5-year loan at 7.75%, interest would be: I = $15,000 * 7.75/100 * 5 = $5,812.50.
So, the 4-year loan at 8.5% will require less interest payment.

What is the constant of variation?
Type your answer as a decimal.
pages per hour.
Answer: [tex]0.8[/tex] pages per hour.
Step-by-step explanation:
For this exercise it is important to know that, by definition, Direct variation equations have the following form:
[tex]y=kx[/tex]
Where "k" is the constant of variation.
Therefore, it is a straight line that passes through the origin.
In this case, given the graph attached in the exercise, you can follow these steps in order to find the constant of variation:
Step 1: You need to choose any point on the line. Let's choose the point (5,4).
Step 2: Now you must ubstitute the coordinates of that point into [tex]y=kx[/tex]. Then:
[tex]4=k(5)[/tex]
Step 3: Finally, you must solve for the Constant of variation "k", in order to find its value. Therefore, you get that this is:
[tex]k=\frac{4}{5}\\\\k=0.8[/tex]

When 238 is divided by the natural number n, the quotient is 3 more than n, and there is no remainder. What is n?
Answer:
n = 14
Step-by-step explanation:
Write the equation in algebraic (numbers and symbols) form
[tex]\frac{238}{n}[/tex] = n + 3 Rearrange the equation
[tex]n\frac{238}{n}[/tex] = n(n + 3) Multiply both sides by 'n'
238 = n(n + 3) On the left, multiplying and dividing by 'n' cancels out
238 = n² + 3n Distributed right side
0 = n² + 3n - 238 Rearranged to standard form for quadratic equations
Remember standard form for quadratic equations is: ax² + bx + c = 0
State the variables a, b and c:
a = 1; b = 3; c = -238
When a quadratic equation is in standard form, you can use the quadratic formula to solve for 'n'. (Usually, you see the variable 'x', but the quadratic formula can solve for 'n' as if it is 'x', as long as it's in standard form.)
[tex]n = \frac{-b±\sqrt{b^{2}-4ac}}{2a}[/tex] (ignore the Â, it's a formatting error)
[tex]n = \frac{-(3)±\sqrt{(3)^{2}-4(1)(-238)}}{2(1)}[/tex] Substitute the values for 'a', 'b' and 'c' from the equation
[tex]n = \frac{-3±\sqrt{9-(-952)}}{2}[/tex] In the root, two negatives make a positive
[tex]n = \frac{-3±\sqrt{9+952}}{2}[/tex] Add inside the root
[tex]n = \frac{-3±\sqrt{961}}{2}[/tex] Find the square root of 961
[tex]n = \frac{-3±{31}{2}[/tex] Split the equation at the ±
Split for adding:
[tex]n = \frac{-3+31}{2}[/tex] Simplify
n = 14
Split for subtracting:
[tex]n = \frac{-3-31}{2}[/tex] Simplify
n = -17
You get the answers 14 and -17 for 'n'. Decide which one is 'inadmissible', meaning it can't be right even if it solves the equation.
The problem says 'n' is a natural number. Natural numbers are all non-partial numbers count up from 1. (Non-partial means as a fraction, they are reduced to a number over 1). Since -17 is less than 1, it is inadmissible because it is not a natural number.
Therefore, 'n' is 14.
fill in the blanks 1 1/2 is ____ % of 7 1/2 ; 7 1/2 is ____ % of 1 1/2
Answer:
20; 500
Step-by-step explanation:
1.5 is what percent of 7.5. 7.5 is 5 times 1.5, so 1.5 is 1/5 of 7.5. 1/5=20%. Inversely, 7.5 is 5 times 1.5, 5=500%.
[tex]1 \frac{1}{2} \text{ is } \underline{20\%} \text{ of } 7 \frac{1}{2}[/tex]; [tex]7 \frac{1}{2} \text{ is } \underline{500\%} \text{ of } 1 \frac{1}{2}[/tex]
First, convert the mixed numbers to improper fractions:[tex]1 \frac{1}{2}[/tex] becomes [tex]\frac{3}{2}[/tex].
[tex]7 \frac{1}{2}[/tex] becomes [tex]\frac{15}{2}[/tex].
To determine the percentage, we use the percentage formula:[tex]\text{Percentage} = \frac{\text{part}}{\text{whiole}} \times 100\%[/tex]
Determine what percentage of [tex]1 \frac{1}{2}[/tex] is [tex]7 \frac{1}{2}[/tex]:[tex]\frac{\frac{3}{2}} {\frac{15}{2}} \times 100\% = \frac{3}{15}\times 100\% = \frac{1}{5}\times 100\% = 20\%.[/tex]
Thus,
[tex]1 \frac{1}{2} \text{ is } \underline{20\%} \text{ of } 7 \frac{1}{2}.[/tex]
For the second part, determine what percentage [tex]7\frac{1}{2}[/tex] is of [tex]1 \frac{1}{2}[/tex]:[tex]\frac{\frac{15}{2}} {\frac{3}{2}} \times 100\% = \frac{15}{3}\times 100\% = 5\times 100\% = 500\%.[/tex]
Thus,
[tex]7 \frac{1}{2} \text{ is } \underline{500\%} \text{ of } 1 \frac{1}{2}.[/tex]

4/5 is greater than less then or equal to 1/2
Greater Than!
First make the denominator (the bottom number) the same for both fractions. So you can multiply the 1/2 by 5 and the 4/5 by 2.
This will make them 5/10 and 8/10.
Then, you see that 8/10 (4/5) is greater than 5/10 (1/2)
Hope that’s makes sense! :)
The fraction 4/5 is greater than 1/2. This conclusion can be reached by converting the fractions to decimal form, where 4/5 becomes 0.8 and 1/2 becomes 0.5, highlighting that 0.8 is indeed greater than 0.5.
Explanation:The question is whether the fractional value of 4/5 is greater than, less than, or equal to 1/2. To compare these fractions, it may be helpful to first convert them to decimal form, as this is often easier to understand than comparing fractions directly. 4/5 as a decimal is 0.8 and 1/2 as a decimal is 0.5. Hence, 0.8 is greater than 0.5. Therefore, 4/5 is greater than 1/2.

Answer:
Step-by-step explanation:
a vertical line has an undefined slope....(8,6).....its equation is x = 8 because no matter what y is, x will always be 8.
but u need it in standard form Ax + By = C
so it is written as : x + 0y = 8 <===
A = 1
B = 0
C = 8
Ax + By = C will be a vertical line passing through point (8,6) for values of A = 1 , B = 0 and C = 8.
What is a vertical line ?
In a coordinate plane, a line parallel to the Y-axis is called vertical Line. Any point in this line will have the same value for the x-coordinate.
We know that the x-axis has lines that run vertical then if you have a point use your x-ordinate.
The equation of a vertical line is :
x = C
here : C is the value of the x- coordinates the line passes through.
In the given question we have to find out the values of A , B and C for which Ax + By = C be a vertical line passing through point (8,6).
Here , the coordinate of point (x , y) is (8 , 6).
So , the equation of vertical line will be x = 8.
So , if we compare it with the general form of line , Ax + By = C, then we get :
8A + By = 8
So , values of A , B and C :
A = 1, B = 0, C = 8
Therefore , Ax + By = C will be a vertical line through point (8,6) for values of A = 1 , B = 0 and C = 8.

Step-by-step explanation:
Two cars got an oil change at the same auto shop. The shop charges customers for each quart of oil plus a flat fee for labor. The oil change for one car required 5 quarts of oil and cost $24.80. The oil change for the other car required 7 quarts of oil and cost $29.30. How much is the labor fee and how much is each quart of oil?
The labor fee is $13.55 and each quart of oil is $2.25
Step-by-step explanation:
Let,
x be the amount of each quart of oil
y be the amount of labor fee
According to given statement;
5x+y=24.80 Eqn 1
7x+y=29.30 Eqn 2
Subtracting Eqn 1 from Eqn 2
[tex](7x+y)-(5x+y)=29.30-24.80\\7x+y-5x-y=4.50\\2x=4.50[/tex]
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{4.50}{2}\\x=2.25[/tex]
Putting x=2.25 in Eqn 1
[tex]5(2.25)+y=24.80\\11.25+y=24.80\\y=24.80-11.25\\y=13.55[/tex]

Write the equation of a line that contains (2,-4) and that is perpendicular to y=2/3x+2
Answer:
y = - [tex]\frac{3}{2}[/tex] x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{3}[/tex] x + 2 ← is in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex], thus
y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, - 4) into the partial equation

cosA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{21}{29}[/tex]
tanA = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{20}{21}[/tex]
The functions sin, cos, and tan for a given angle in a right triangle are defined in terms of ratios of the side lengths. They are respectively the ratios of the opposite side to the hypotenuse, the adjacent side to the hypotenuse, and the opposite side to the adjacent side.
Explanation:In a right triangle, sin(A) is defined as the ratio of the side opposite to angle A (opposite side) to the hypotenuse, cos(A) as the ratio of the adjacent side to the hypotenuse, and tan(A) as the ratio of the opposite side to the adjacent side.
Suppose the lengths of the sides of the given right triangle are a, b, and c (where c is the length of the hypotenuse).

Answer:
$10,000
Step-by-step explanation:
Let x represent the amount invested in the 5.5% bond.
For an annual income of $1800, we want ...
(5.5%)x + (6.25%)(30,000-x) = 1800
(-0.75%)x + 1875 = 1800
-0.0075x = -75 . . . . . . . . . subtract 1875
x = 10,000 . . . . . . . . . . . . . divide by -0.0075
At most $10,000 should be invested at 5.5% to obtain at least $1800 in interest.

Edin has £300 in his savings account.his bank offers him 5% simple intrest rate ped annum for a period of 3 years.how much intrest will he make after 3 years
Answer:
$45
Step-by-step explanation:
We are given the following information;
Money invested (Principal) is $300Rate of interest is 5% per annumTime the money is invested is 3 yearsWe need to determine the amount of interest the money will earn after three years.
Simple interest is calculated by the formula;Simple interest =(PRT) ÷ 100, Where P is the principal amount, R is the rate of interest and T is the time.Therefore, in this case;
Simple interest = ($300 × 5 × 3) ÷ 100
= $45
Thus, the money invested earned a simple interest of $45
Using the formula for simple interest, we find out that Edin will earn £45 as interest on his savings of £300 over a period of 3 years at a simple interest rate of 5% per annum.
Explanation:The subject of this question is simple interest. The formula for simple interest is: Principal * Rate * Time. Let's plug in the given values into the formula. Here, the principal amount is £300, the rate of interest is 5% per annum (or 0.05 in decimal form), and the time is 3 years. So, the calculation will be: £300 * 0.05 * 3.
After performing the calculation, we find that the interest Edin will earn after 3 years is £45.
