Answer:

8a=32

Step by Step

Since David is 8x older than Nicole you could write Nicole as the age of a, so then David would be 8a. You are given David is 32 years old so you set 8a equal to 32.

Answer is 4

Nicole is 4 years old

8a=32

divide both sides by 8

Answer:

$R=\$145.12$

Step-by-step explanation:

<u>Compound Interest</u>

This is a well-know problem were we want to calculate the regular payment R needed to pay a principal P in n periods with a known rate of interest i.

The present value PV or the principal can be calculated with

$P=F_a\cdot R$

Solving for R

$\displaystyle R=\frac{P}{F_a}$

Where Fa is computed by

$\displaystyle F_a=\frac{1-(1+i)^{-n}}{i}$

We'll use the provided values but we need to convert them first to monthly payments

$i=7\%=7/(12\cdot 100)=0.00583$

$n=3*12=36$

$\displaystyle F_a=\frac{1-(1+0.00583)^{-36}}{0.00583}$

$F_a=32.386$

Thus, each payment is

$\displaystyle R=\frac{4,700}{32.386}=145.12$

$\boxed{R=\$145.12}$

Enter and solve an equation to find the complement of an angle that measures 38º.

Studentka2010 [4]

Answer:

52°

Step-by-step explanation:

The sum of an angle and its complement is 90°.

The sum of 38° and its complement, x, is 90°:

38 +x = 90 . . . . . an equation to find the complement of 38°

x = 90 -38 . . . . subtract 38 from both sides

x = 52 . . . . degrees

The measure of x is 52°.

You fly in a helicopter for 1 hour that goes at a speed of 240 km per hour how far did u go

cupoosta [38]

Speed = change in distance divided by change in time

Speed: 240 km/h
Time = 1 h

240 = change in distance divided by 1
Rearrange: change in distance = 240 x 1 = 240. Therefore you go 240 km.
