Answer:

a) 1.8 cm^2

b) 3.6 feet^2

Step-by-step explanation:

Conversion and calculation of areas

The area of a rectangle is A=wh, where w is the width and h is the height. There are 3 feet in one yard

a)

We are told Kalie put 6 stickers, each one of 1/2 centimeters (0.5 cm) wide by 3/5 (0.6 cm) centimeter long. The area of one sticker is

A=(0.5)(0.6)=0.3 cm^2

Assuming there is no overlapping, the 6 stickers have a total area

6*0.3 cm^2=1.8 cm^2

b)

Each of Elana's wrapping papers measures 2/5 yards long and 1/4 yard wide. Converting them to feet we have

long=2/5*3=1.2 feet

wide=1/4*3=0.75 feet

Area of each paper=1.2 feet*0.75 feet=0.9 feet^2

Area of the entire board, assuming no overlapping and no space left uncovered=4*0.9 feet^2

Area of board=3.6 feet^2

Equal amounts are invested at 2%, 7%, and 9% annual interest. If the three investments yield a total of $792 annual interest, fi
mihalych1998 [28]

Answer:

\large \boxed{\$13 200}

Step-by-step explanation:

The formula for simple interest I is

I = Prt, where

P = the principal (amount invested)

r = the interest rate per period and

n = the number of periods

In this problem, the interest rate is annual, so n = 1.

We must write the interest rate as a decimal fraction.

Let x = amount of each investment. Then

0.02x = interest at 2 %

0.07x = interest at 7 %

0.09x = interest at 9 %

0.18x  = total interest

\begin{array}{rcl}0.18x & = & 792\\x & = & \dfrac{792}{0.18}\\& = & 4400\\\end{array}\\\text{Each investment was \$4400.}\\\text{The total investment was 3$\times \$4400$ or $\large \boxed{\mathbf{\$13 200}}$}
