Your cousin borrows $1125 to repair her car. The simple annual interest rate is 10%. She makes equal monthly payments of $25. How many years will it take to pay off the loan?
Answer:
26 months i believe is correct :)
Step-by-step explanation:
The number of years it will take to pay off the loan will be 4.125 years based on simple interest.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.
As per the given,
Total loan = $1125
Rate of interest R = 10%
Monthly payment = $25
Yearly payment = 25 x 12 =$300
Suppose it takes T years,
Total amount A = principle P + interest
A = 1125 + 10% of 1125
A = 1125 + 0.10 x 1125
A = $1237.5
The number of years it will take will be as follows,
Total amount / yearly payment
⇒ 1237.5/300
⇒ 4.125 years.
Hence"The number of years it will take to pay off the loan will be 4.125 years based on simple interest".

5t=
Subtract 8 from both sides
t=
Divide both sides by 5
Answer:
t = 1
Step-by-step explanation:
5t + 8 = 13
Subtract 8 from both sides
5t + 8 - 8 = 13 - 8
5t = 5
Divide both sides by 5
5t/5 = 5/5
t = 1
Check:
5t + 8 = 13
5(1) + 8 = 13

Help pls, answer choices listed also
Answer:
A.
Step-by-step explanation:
Hi there!
By factoring the trinomial, we end with (x-9)(x-4)
However, we aren’t done yet. To find the zeros, set each expression equal to zero, so it looks something like this.
0 = x - 9
0 = x - 4
Using orders of operations, x = 9 and x = 4
Therefore, A is your answer.

If x = 45, y = 63, and the measure of AC = 4 units, what is the difference in length between segments AB and AD? Round your answer to the nearest hundredth.
0.74 units
1.17 units
1.64 units
2.14 units
Answer:
1.17
Step-by-step explanation:
(MUCH BETTER!)
From the definition of the sin of an angle, you know:
sin(45°) = AC/AB = 4/AB ⇒ AB = 4/sin(45°) ≈ 5.6569
sin(63°) = AC/AD = 4/AD ⇒ AD = 4/sin(63°) ≈ 4.4893
Then the difference AB-AD is:
AB -AD = 5.6569 -4.4893 = 1.1676
AB -AD ≈ 1.17 units

The trapezoid below has been enlarged by a scale of 1.5. What is the area of the enlarged trapezoid?
Answer:
New area by scale of 1.5 = 81 in²
Step-by-step explanation:
Given:
Current area = 36 in²
Find:
New area by scale of 1.5
Computation:
New area by scale of 1.5 = Current area x (scale factor)²
New area by scale of 1.5 = 36 x (1.5)²
New area by scale of 1.5 = 36 x (2.25)
New area by scale of 1.5 = 81 in²
Answer:
B.
Step-by-step explanation:
We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5.
We are asked to find the area of the enlarged trapezoid. The area of the original trapezoid is 36 square inches.
Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.
The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.
Therefore, the area of the enlarged trapezoid would be and option B is the correct choice.

What is the equation of a parabola that intersects the x-axis at points (-1, 0) and (3, 0)?
A. y = x2 – 2x – 3
B. y = x2 + 3x + 2
C. y = x2 – 3x + 2
D. y = x2 + 2x – 3
Answer:
A. y = x² – 2x – 3Step-by-step explanation:
The given points are zero's or roots of the function.
We can put the equation as:
y = (x + 1)(x - 3) = x² -3x + x - 3 = x² - 2x - 3This is option A

write 34 as a product of its prime factors. PLEASE HELP I NEED TO TURN IT IN IN % MINUTES
Answer: Down below
Step-by-step explanation: First of all, as 34 is an even number, so it must be divisible by smallest prime 2.
Thus, 2 must be a factor of 34.
Now, look for number obtained on dividing 34 by 2 i.e.
34÷2=17.
So, 17 is our new number.
Now, look for factors/divisors of 17, which are precisely 1 and 17 i.e. 17 is itself a prime.
This implies only factors possible for 34 are 2 and 17.
Thus ,34 can be written as product of prime numbers 2 and 17 as 34=2×17.
Key idea. Given any number, divide it by smallest divisible prime and look for the number obtained on division.
Now, repeat the process for the number obtained.
If no division by a smaller prime than that number is possible, then our number is itself a prime.

2(17)

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Your answer would be 189
Step-by-step explanation:
if you break the figure in to smaller parts you get for the two triangles 12*9/2. There are two of them, so that gets you 12*9/2+12*9/2, and all that equals 108. Finally, there is one more square in the middle, which equals 81, so 108+81=189, which is your answer.
