A new car that sells for $44,000 depreciates 25% each year. Write a function that models the value of the car. Find the value of the car after 4 years.
can you answer the equation to? please hurry!
Answer:
Value = 44,0000(0.75)^t
Where t = number of years
Value after 4 years = 44,000 (0.75)^4

Find the measure of the angle marked “?”
Answer:
137
Step-by-step explanation:
A linear pair adds up to 180 so if you subtract 180 minus 43 its 137 (a)
Then since a parallel line cut by a transversal forms alternate interior angles, (b) would equal 137 also
The since vertical angles are congruent, (b) is equal to ? which is 137

Find the measure for
A)
127°
B)
131°
C)
135°
D)
139°
Answer:
B) 131°
Step-by-step explanation:
-4a + 139 = 4a + 123 because they are vertical angles
-4a + 139 = 4a + 123
reduce:
8a = 16
a = 2
4(2) + 123 = 131°

Lin says she has memorized the lengths of a few right triangles, for example, 3, 4, and 5. She is trying to compile a list of several right triangles but needs your help. Find the side lengths of at least two other right triangles.
Answer:
6-8-10
9-12-15
5-12-13
Step-by-step explanation:
We know the 3-4-5 right triangles work when you multiply the sides by anything. For example. 6-8-10 and 9-12-15 work.
If you want other right triangles that follow a similar pattern, 5-12-13 is also viable. 10-24-26 & 15-36-39 are all right triangles
The 6, 8, 10, and 9, 12, and 15 are other sides of the right-angle triangle after applying Pythagoras theorem.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
We have:
Lin says she has memorized the lengths of a few right triangles, for example, 3, 4, and 5.
There are 6, 8, 10, 9, 12, and 15 other sides of the right-angle triangle.
On applying Pythagoras theorem.
6² + 8² = 10²
9² + 12² = 15²
Thus, the 6, 8, 10, and 9, 12, and 15 are other sides of the right-angle triangle after applying Pythagoras theorem.

What is the volume and total surface area?? PLEASE HELP
Step-by-step explanation:
the volume would be inside of the spear so i could be wrong but you would do 10 multiplied by 21 and you get 210. IF you did base and height the base would be 10ft and the height would be 21ft then you just do base times height and that gets you 210 . i could be wrong though
In the sequence: 20, 25, 23, 28, 26, …, what number should come next?
a) 24
b) 31
c) 21
d) 28
Answer:
b) 31
Step-by-step explanation:
20 + 5 = 25
25 - 2 = 23
23 + 5 =28
28 - 2 = 26
pattern: add 5 then subtract 2
since we subtract last, we would add 5 on 26:
26 + 5 = 31
Answer:
31
Step-by-step explanation:
In the sequence they are adding 5 and taking away 2. So if they start with 20, they added 5 and took away 2, it was 23. Then they added 5 again and it was 28, they took away 2 and it was 26. If they add 5, the next number would be 31.
Hope it helped :)

Arectangle has a width that is 8 centimeters less than its length. The perimeter of the rectangle is 56 centimeters. Find both the width and length of the rectangle. Show your work.
Answer:
L=18cm
W=10cm
Step-by-step explanation:
Given data
let the length be x
L=x
Width= x-8
W= x-8
Perimeter= 56cm
But we know that the perimeter is expressed as
P=2L+2W
substitute our data
56=2(x)+2(x-8)
56=2x+2x-16
56+16=4x
72=4x
divide both sides by 4
x= 72/4
x=18cm
Hence the Length is 18cm
L=18cm
The width= 18-8
W=10cm

HELP WITH PLEASE! I’ll give you brilliance
Answer:
a:95
b: a=75
Step-by-step explanation:
For a:
The angles are supplementary meaning they add to 180º. So you can set up an equation: x + 85 = 180
Subtract 85 from both sides:
x = 95º
For b:
Since it's an isosceles triangle (2 congruent sides), the base angles are equal to each other. So a = 75º
One day a retail store received a box of 24 shirts. If this shipment had 6 defective shirts, what can the store expect for upcoming shipments?
Answer:
1 /4
Step-by-step explanation:
Given that:
Number of shirts in shipment = 24
Number of defective shirts in shipment = 6
The expectation about upcoming shipment which can be inferred from the information give is the probability of defect in upcoming shipments :
Probability of defect = Number of defect in shipment / total number of items in shipment
P(defect) = 6 /24 = 1 /4
Meg and Theo each thought of five numbers. Meg's first number was 0, and so was Theo's. Meg added 2 each time to get her other numbers, and Theo added 4 each time. Which statement correctly compares Theo and Meg'snumbers? A Each of Theo's numbers is 2 more than Meg's corresponding number, because Theo adds 2 more than Meg to get the next number. B Each of Theo's numbers is half of Meg's corresponding number, because Theo adds half as much as Meg to get the next number. C Each of Theo's numbers is 4 more than Meg's corresponding number, because Theo adds 4 each time to get the next number. D Each of Theo's numbers is double Meg's corresponding number, because Theo adds twice as much as Meg to get the next number.
Answer:
D. Each of Theo's numbers is double Meg's corresponding number, because Theo adds twice as much as Meg to get the next number.
Step-by-step explanation:
Meg = 0, 2, 4, 6, 8
Theo = 0, 4, 8, 12, 16
Second number of Theo is 4 which is double of 2 (Meg second number)
This applies to the third, fourth and fifth number of Theo
Therefore,
Each of Theo's numbers is double Meg's corresponding number, because Theo adds twice as much as Meg to get the next number.
