Answer: $9,521
Step-by-step explanation:
In such cases, you should use the future value formula which is:
Future value = Amount * (1 + rate) ^ number of periods
Rate = -15% because the value is decreasing.
Future value = 21,459 * (1 -15%)⁵
= $9,521
Car will be valued at $9,521 after 5 years.

Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Penny buys 3 bouquets of flowers for $3 each and 4 bouquets for $2 each.
The expression that gives the total cost of the bouquets that Penny buys will be:
= (3 × $3) + (4 × $2)
Solving further will be:
= (3 × $3) + (4 × $2)
= $9 + $8

A scale drawing of an ant uses a scale of 1 centimeter = 2.5 millimeters. If the actual ant is 10 millimeters long, find the length of the ant on the drawing.
Answer:
4 Centimeters
Step-by-step explanation:
If 1 centimeter is 2.5 millimeters, then 4 centimeters is 10 millimeters because 2.5 x 4 = 10 or 10/2.5 = 4
Keith is 5 years older than Trina. Two times the sum of their ages is 62. Write and solve an equation to find Keith’s age.
Answer:
Trina is 13
Kieth is 18
Step-by-step explanation:
x + 5 = Kieth's age
Divide by 2 to separate the ages:
62 ÷ 2 = 31
Subtract the difference in ages:
31 - 5 = 26
Add the 5 years to Kieth's age:
31 + 5 = 36
Divide by 2 again, to eliminate the twice of their ages
26 ÷ 2 = 13
36 ÷ 2 = 18
Trina is 13
Kieth is 18

2xy +1 = 1
solve for x
Answer:
the answer of this question is 0
A. First, convert this equation into y-intercept form
y = 2x + 1
B. 2 is the slope: 1 is the y-intercept
Then, plug in 1 for y and solve
C. 1 = 2x + 1
Therefore, x is 0

The hypotenuse of a right triangle is 10 ft long the longer end is 2 ft longer than the shorter leg. Find the side lengths of the triangle
Answer:
The sidelength of the triangles is 6 feet and 8 feet.
Step-by-step explanation:
Given that,
The Hypotenuse of a right triangle = 10 feet
Let the shorter leg is x. It means the longer leg is (x+2).
For a right triangle,
Hypotenuse²=base²+perpendicular²
So,
[tex]10^2=x^2+(x+2)^2\\\\100=x^2+x^2+4+4x\\\\100=2x^2+4x+4\\\\2x^2+4x+4-100=0\\\\2x^2+4x-96=0\\\\x^2+2x-48=0\\\\(x+8)(x-6)=\\\\x=-8,6[/tex]
The side length of a triangle can't be negative. It means that the length of the shorter length is 6 feet and that of the longer leg be 8 feet.

A scale drawing of a house shows 9cm x10cm. If
6cm=12 ft, what are the actual dimensions?
Answer:
18ft x 20ft
Step-by-step explanation:
(I'm kinda in a rush so I can't explain right now, sorry!)
Hope that helped though :)
The actual dimensions of the house is 18 feet by 20 feet.
Scaling is used to either increase or decrease the size of a figure to create an image.
Given that a scale of 6cm to represent 12 ft. Hence:
9 cm = 9 cm * (12 ft. per 6 cm) = 18 feet.
10 cm = 10 cm * (12 ft. per 6 cm) = 20 feet.
The actual dimensions of the house is 18 feet by 20 feet.

Kali and Ryan are selling cheesecakes for a school fundraiser. Customers can buy New York style cheesecakes and apple cheesecakes. Kali sold 12 New York style cheesecakes and 1 apple cheesecake for a total of $79. Ryan sold 14 New York style cheesecakes and 1 apple cheesecake for a total of $91. Find the cost each of one New York style cheesecake and one apple cheesecake.
Answer:
New York style cheesecake: $6 Apple cheese cake: $7
Step-by-step explanation:
Ryan and Kali sold the same amount of apple cheesecakes which means the New York cheesecakes differed in amount. Ryan sold 2 more than Kali so the difference in amount would be the cost of 2 New York cheese cakes.
Ryan made $91 and Kali made $79. Since they sold the same amount of apple cheesecakes, we can use their difference in money made to find the cost of 2 New York cheesecakes. So take away 79 from 91 and you get 12. $12 is the price of 2 New York cheesecakes. So take the 12 and divide it by 2. You get 6. $6 is the price of one New York cheesecake.
To find the amount of one apple cheesecake, you just need to multiply the amount of New York cheesecakes Kali sold by the price of 1 New York cheesecake. So 6 multiplied by 12 is equal to 72. Take the money Kali made and take away 72 from it. You get 7. 7 is the cost for one apple cheesecake. $7 for 1 cheesecake.

What is the area of the trapezoid? [A = 5(61 + b2)h]
202 ]
A) 1249.5 sq cm
B) 162.75 sq cm
C) 105 sq cm
D) 38.75 sq cm
Answer:
A = 105 cm²
Step-by-step explanation:
The area (A) of the trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] [ (b₁ + b₂)h ]
where h is the height and b₁, b₂ the parallel bases
Here h = 5 , b₁ = 24 and b₂ = 18 , then
A = [tex]\frac{1}{2}[/tex] [ (24 + 18)5 ]
= [tex]\frac{1}{2}[/tex] (42 × 5)
= [tex]\frac{1}{2}[/tex] × 210
= 105 cm²
If lucas puts $1500 in a saving account that pays 3% interest compounded annually, how much money will he have in the account after 5 years?
Answer:A = 1500e^(0.03 * 5) = 1500e^(0.15)
use definition of logarithm
0.15 = ln(A / 1500)
0.15 = ln(A) - ln(1500)
ln(A) = 0.15 + ln(1500) = 0.15 + 7.313220387 = 7.463220387

Calculate the angular momentum that keeps an 80-kg person sitting on the edge of a horizontal rotating platform when the person sits 2 m from the center of the platform and has a tangential speed of 3 m/s
Answer:
[tex]L=480\ kg-m^2/s[/tex]
Step-by-step explanation:
Given that,
Mass of a person, m = 80 kg
The distance from the centre of the platform, r = 2 m
The tangential speed of the platform, v = 3 m/s
We need to find the angular momentum of the person. The formula for the angular momentum is given by :
[tex]L=mvr\\\\L=80\times 3\times 2\\\\L=480\ kg-m^2/s[/tex]
So, the required angular momentum is equal to [tex]480\ kg-m^2/s[/tex].
Answer:
Tangential speed is 0.68 m/s
Explanation:
It is given that,
Mass of the beetle, m = 0.023 kg
It is placed at a distance of 0.15 m from the center of record i.e. r = 0.15 m.
If it takes 0.070 n of force to keep the beetle moving in a circle on the record i.e. centripetal force acting on it is, F = 0.070 N
We have to find the tangential speed of the beetle. The formula for centripetal force is given by :
v is tangential speed
v = 0.675 m/s
or
v = 0.68 m/s
Hence, the correct option for tangential speed is (A).

A dressmaker needs to cut 9-inch pieces of ribbon from rolls of ribbon that are 3 feet in length. How many 9-inch pieces can the dressmaker cut from 5 of these rolls of ribbon? Before you try that problem, answer the question below. How many \textbf{inches}inches of ribbon does the dressmaker have, in total?
Answer: 20
Step-by-step explanation:
First and foremost, we should know that: 12 inches = 1 foot. Therefore converting 3 feet to inches will be:
= 3 × 12 = 36 inches.
Therefore, if a dressmaker needs to cut 9-inch pieces of ribbon from rolls of ribbon that are 3 feet in length. The number of pieces will be:
= 3 feet / 9 inch
= 36 inches / 9 inches
= 4 pieces
Then, the number of 9-inch pieces that the dressmaker can cut from 5 of these rolls of ribbon will be:
= 4 × 5
= 20 pieces
