Answer:

4.2

Step-by-step explanation:

1 $\frac{2}{5}$ ÷ $\frac{1}{3}$

Divide $\frac{1 x 5+2}{5}$ by $\frac{1}{3}$ by multiplying $\frac{1 x 5+2}{5}$ by the reciprocal of $\frac{1}{3}$

$\frac{( 1 x 5 + 2) x 3}{5}$

Add 5 and 2 to get 7.

$\frac{7 x 3}{5}$

Multiply 7 and 3 to get 21.

$\frac{21}{5}$

Factor

$\frac{3.7}{5}$ = 4 $\frac{1}{5}$ = 4.2

A student has a savings account earning 3% simple interest. She must pay $1200 for first-semester tuition by September 1 and $12

Bingel [31]

Using simple interest, it is found that she needs to earn $2,391.07 during the summer.

<h3>Simple Interest</h3>

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

A(t) = A(0)(1 + rt)

In which:

A(0) is the initial amount.

r is the interest rate, as a decimal.

For this problem, the objective is to have <u>$1200 in 3 months = 0.25 years</u>, hence the parameters are given as follows:

A(0.25) = 1200, t = 0.25, r = 0.03.

Hence we have to solve for A(0):

A(0)(1 + 0.03 x 0.25) = 1200

A(0) = 1200/(1 + 0.03 x 0.25)

A(0) = $1,191.07.

She also needs to earn $1,200 to pay the first-semester bill on time, hence:

1200 + 1191.07 = $2,391.07.

She needs to earn $2,391.07 during the summer.

5.Karen is thinking of a number. If she multiplies her number by −3 and then adds 6, she has −4 times the original number. What

alekssr [168]

-3x+6 = -4x

6 = -x

x = -6

check:

-6*-3 = 18 +6 =24

-6*-4 = 24

number = -6

The table below shows the cube roots of different numbers: Number (x) 27 −27 125 −125 Cube root of the number (y) 3 −3 5 −5

kolbaska11 [484]

Part A

The table does represent y as a function of x because each input (values of x) related to exactly one output. Refer to the diagram below.

Part B

We have
f(x) = 925x + 1000
f(24) = 925 (24) + 1000
f(24) = 23200

f(24) represent the value of renting for 24 months
