Matt paid $450 in interest on a 15 month note for<br> $5600. Find the rate of interest paid.
Olin [163]

Answer:

The rate is 6.43%

Step-by-step explanation:

Given

I = 450 --Interest

P = 5600 -- Principal

T= 15\ months --Time

Required

Determine the rate

Using simple interest formula:

I = PRT

Make R the subject

R = \frac{I}{PT}

Convert time to years

T= 15\ months

T =\frac{15}{12}\ years

T =1.25\ years

Substitute values for I, P and T

R = \frac{450}{5600*1.25}

R = \frac{450}{7000}

R = 0.0643

Convert to percentage

R = 0.0643*100\%

R = 6.43\%

Help me, but the answer is not E.
olga55 [171]

Answer:

40%

Step-by-step explanation:

To find the percentage difference between the families with 2 dogs and the families with no dogs, we need to find their difference first.

Difference = 45 - 27

                  = 18

Now that we know the difference, we just have to put the difference over the total as a fraction and multiply by 100%.

Percentage difference = \frac{18}{45} × 100%

                                      = 40%

Evaluate f(t)=-2t2+ 1 for f(-3).
podryga [215]

Answer:

7

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

f(-3)=-2(-3) +1

Second, multiply -2 and -3 to get 6:

f(-3)=-2(-3)+1⇒f(-3)=6+1

Third, add 6 and 1 to get your answer:

f(-3)= 6+1⇒f(-3)=7
