Area of the rectangle = L X W

Area of the rectangle = 4 X 2

Area of the rectangle = 8 inches

If the drawing is 1/5 of the actual air conditioning unit, then you multiply the reciprocal which is 5 times the area of the drawing. When you want to enlarge it has to be a whole number. When you want to reduce you multiply by a fraction.

So 8 inches X 5 = 40 inches is the actual area of the unit.

Carolyn borrowed $38,500 to pay
for college. If the interest rate is
3.2%, how much total will she
have paid after 10 years?

Answers

Answer:

$50820

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.2%/100 = 0.032 per year,

then, solving our equation

I = 38500 × 0.032 × 10 = 12320

I = $ 12,320.00

The simple interest accumulated

on a principal of $ 38,500.00

at a rate of 3.2% per year

for 10 years is $ 12,320.00.

The Answer is 2nd one

69.08 cm

Explanation :

Given :

Radius of a circle = 11 cm

To Find :

Circumference of the circle = ?

Solution :

As, we have radius of the circle is 11 cm and to find circumferemce, we have a formula :

[tex] \large \underline{\boxed{\bf{Circumference = 2\pi r}}}[/tex]

By filling value of r = 11 cm and π = 3.14, we have :

[tex] \sf : \implies Circumference = 2 \times 3.14 \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = 2 \times \dfrac{314}{100} \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = \dfrac{628}{100} \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = \dfrac{6908}{100} \: cm[/tex]

[tex] \sf : \implies Circumference = 69.08\: cm[/tex]

Hence, circumference of the circle is 69.08 cm.
