9. A new automobile costs $23,782,
but after one year it is worth
$17,668. What is the approximate
percent of decrease in the value of
the automobile?
Answers
Answer:
% decrease in the cost= 6114/23782⋅100=25.71%
Step-by-step explanation:
The decrease in the cost =$23782−$17668=$6114
Hence, % decrease in the cost=6114/23782⋅100=25.71%
the decrease is 23782 - 17668 = 6114.
if we take 23782 to be the 100%, what is 6114 off of it in percentage?
[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 23782&100\\ 6114&x \end{array}\implies \cfrac{23782}{6114}=\cfrac{100}{x}\implies 23782x=611400 \\\\\\ x=\cfrac{611400}{23782}\implies x\approx 25.71[/tex]

Surface area of prisms and cylinders

Answer:

2. LA = 460 sq. in., SA = 700 sq. in.
3. LA = 118 sq. in., SA = 168 in. sq.
4. LA = 468 sq. cm., SA = 828 sq. cm.
Step-by-step explanation:
The lateral area is the area of the non-base faces. The surface area is the area of all the faces (so lateral area + area of base).
1.
Lateral area:
There are 2 same triangles each with height and base of 3 and 4, respectively. So
Area of triangle = 1/2 * base * height = 1/2 * 4 * 3 = 6
Since there are 2, so 6 * 2 = 12
Now, the slant height is gotten by using pythagorean theorem on the triangular face.
[tex]4^2+3^2=SlantHeight^2\\16+9=SlantHeight^2\\25=SlantHeight^2\\SlantHeight=5[/tex]
If you look at the side facing away, it is a rectangle with length 10 and width 5, so area of rectangle is length * width = 10 * 5 = 50
The side facing towards us is also a rectangle with dimensions 3 and 10. So area is 3 * 10 = 30
The lateral area is 30 + 12 + 50 = 92
Surface Area:
This is the lateral area we got before (92) + the area of the base.
The base is a rectangle with dimensions 4 and 10. So area = 4 * 10 = 40
The surface area is 92 + 40 = 132
2.
Lateral area:
all the faces are rectangles.
The dimensions of two side faces are 10 and 8. So area would be 2 * (10 * 8) = 2 * 80 = 160
The dimensions of back side and front side is 15 and 10. So area would be 2 * (15 * 10) = 2 * 150 = 300
The lateral area would be 160 + 300 = 460
Surface area:
the surface area is the lateral area (580) + the area of the bases (which is also a rectangle). The dimensions of the bottom and top are 15 and 8. So area of bottom and top is 2(15 * 8) = 240
Thus, surface area = 460 + 240 = 700
3.
Lateral Area:
There are two rectangles (left and right) with dimensions 8 x 5 and 6 x 5. So area would be 8 * 5 = 40 and 6 * 5 = 30. Area = 40 + 30 = 70
There are two triangles (back and front) with base of 6 and height of 8. The area of both are:
(1/2 * 6 * 8 ) * 2 = 48
Lateral area is 70 + 48 = 118
Surface area:
The surface are would be lateral area (118) PLUS the base, which is a rectangle with dimensions 5 and 10. So area = 5 * 10 = 50.
Total surface area = 118 + 50 = 168
4.
lateral area:
there are 2 rectangles (left and right) with dimensions 10 x 12, and 9 x 12. So the total area would be:
(10*12) + (9*12) = 228
The front and back are trapezoids. The area of trapezoid is 1/2 (base1 + base2) * height.
The height is 8 and both the bases are 10 and 20. Plugging it into the formula, we get are of 2 of the trapezoids to be:
2 * (1/2(base1+base2)*height)
2 * (1/2(10+20)*8)
= 240
The lateral area = 228 + 240 = 468
surface area:
it will be 468 (lateral area) PLUS the area of the bases. The bottom base is a rectangle with dimensions 20 and 12. So the area of the base is 20 * 12 = 240
The top is a rectangle with dimensions 12 and 10. So area = 12 * 10 = 120
Surface area = 468 + 240 + 120 = 828

Points to remember
Simple interest
I = PNR/100
Where P - Principle amount
N - Number of years and
R - Rate of interest
To find the simple interest
Here P = $300, R = 5% and N = 7 years

Joel and Sara want to know the combined amount of money they made last week. They both made $9.75 per hour, but Joel also made an $18 bonus. Joel says the combined amount is 9.75j + 18 + 9.75s, where j is the number of hours he worked, and S is the number of hours Sara worked. Sara says the combined amount is 9.75(j + S)+ 18. Who is correct? Explain.
Answers
The would both be correct in it's own way depending on how the teacher is teaching.
Both Joel and Sara are correct. Their expressions represent the combined earnings accurately, considering hourly wage and bonus.
To determine who is correct, let's first break down the earnings for each person:
1. Joel:
- Hourly wage: $9.75
- Bonus: $18
Joel's total earnings can be calculated using the formula provided: [tex]\(9.75j + 18\)[/tex], where [tex]\(j\)[/tex] represents the number of hours Joel worked.
2. Sara:
- Hourly wage: $9.75
Sara's total earnings can be calculated using the formula provided: [tex]\(9.75(j + S)\)[/tex], where [tex]\(S\)[/tex] represents the number of hours Sara worked.
Now, let's expand both expressions and see which one correctly represents the combined earnings of Joel and Sara.
Joel's expression: [tex]\(9.75j + 18 + 9.75S\)[/tex]
Sara's expression: [tex]\(9.75j + 9.75S + 18\)[/tex]
Comparing the two expressions, we see that both expressions have the same terms: [tex]\(9.75j\)[/tex], [tex]\(9.75S\)[/tex], and [tex]\(18\)[/tex]. The order of terms is different, but mathematically it doesn't matter since addition is commutative.
So, both Joel and Sara are correct. They just wrote their expressions in a different order, but the mathematical result is the same. They both correctly accounted for their hourly wage and the bonus.

in triangle ABC the measure of A is 33° and the measure of C is 90° . what is the measure of B
Answers
Answer:
57°
Step-by-step explanation:
ALL angles in a triangle add up to 180°
SO, if we know the sum of two angles which is 123° (why: 33+90=123), all we have to do is subtract this number from 180 to get the measure of the 3rd angle. Which in this case is 57°
The measure of angle B will be 57° for the given triangle.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right angle triangle, equilateral triangle, and much more.
The sum of all three interior angles of any triangle is 180°.
So,
A + B + C = 180°
Given,
A = 33° and C = 90°
33° + B + 90° = 180°
B = 180 - (90 + 33)
B = 180° - 123°
B = 57°
Hence, The measure of angle B will be 57° for the given triangle.

you invest $2800 in an account that pays an interest of 5.5%, compounded continuously. calculate the balance of your account after 12 years. round answer to the nearest hundredth. LAST QUESTION AND I NEED IT CORRECT PLSSS
Answers
Hi, hope this helps you. Have a good day. :)
Answer:
A = $5,417.42 (balance of the account)
I = $2,617.42
Answer:
The balance in the account after 12 years is $5417.42
Step-by-step explanation:
* Lets talk about the compound continuous interest
- Compound continuous interest can be calculated using the formula:
A = P e^rt
• A = the future value of the investment, including interest
• P = the principal investment amount (the initial amount)
• r = the interest rate
• t = the time the money is invested for
- The formula gives you the future value of an investment,
which is compound continuous interest plus the
principal.
- If you want to calculate the compound interest only, you need
to deduct the principal from the result.
- So, your formula is:
Compounded interest only = Pe^(rt) - P
* Now lets solve the problem
∵ P = $ 2800
∵ r = 5.5/100 = 0.055
∵ t = 12
∴ A = 2800 e^(0.055 × 12) = $5417.42
* The balance in the account after 12 years is $5417.42

y=mx+b
slope m = - 1/2
The slope of a line parallel to another line will be the same
The slope of the required line will be - 1/2
m= - 1/2 ,point ( 6 , 4 )
Plugging the values of m and the point in
y=mx+b

Juan has two machines: one exchanges 1 white token into 4 red tokens, while the other exchanges 1 red token into 3 white one. Juan has 4 white tokens. After exactly 11 exchanges , he has 31 tokens. How many of those are red?
Answers
Answer:
14 are red
Step-by-step explanation:
Let's identify the 2 types of transactions Juan machines do:
w : changes 1 white token into 4 red tokens (gain: 3 tokens overall)
r : changes 1 red token into 3 white tokens (gain: 2 tokens overall)
We know that Juan does 11 trades, so we can say:
w + r = 11
Overall, Juan started with 4 tokens and ends with 31... so, gain of 27 tokens.
We can model this as:
3w + 2r = 27
(3w because each w transaction, he gains 3 tokens, 2r because every r transaction, he gains 2 tokens).
From first equation we get r = 11 - w, which we place in the second equation:
3w + 2 (11 - w) = 27
3w + 22 - 2w = 27
w = 5, so r = 6 (from first equation).
Now, we know Juan did 5 w transactions and 6 r transactions. But how many token of each color does he have?
Start: 4W (4 White chips)
He does 4 w transactions, he now has 16R tokens
He does 6 r transactions, he now has 10 (16-6) R tokens, plus 18 W tokens
He does another w transaction, he now has 14 R (10 + 4), plus 17 W(18-1) tokens
He did 11 transactions, and he has 31 tokens at the end, out of which 14 are red.
Which equation is y=(x+3)^2 +(x+4)^2 rewritten in vertex form ?
Answers
Answer:
option B
Step-by-step explanation:
Given in the question an equation y = (x+3)² + (x+4)²
Step 1
Expand this equation
y = (x+3)² + (x+4)²
y = (x²+9+6x) + (x²+16+8x)
y = 2x² + 14x + 25
Step 2
Find the minimum point of the parabola equation, y = 2x² + 14x + 25
y = ax² + bx +c
x = -b/2a
= -14/2(2)
= -14/4
= -7/2
Step 3
Find the vertex point by plugging value of x in the equation
y = 2(-7/2)² + 14(-7/2) + 25
= 49/2 - 49 + 25
= 1/2
vertex (h,k)
vertex (-7/2 , 1/2)
Step 4
vertex form
y = a(x - h)²+ k
y = 2(x + 7/2)² + 1/2
