Answer:

The answer is 12/5 hours

Step-by-step explanation:

As Marcus paints at the same rate so the time to paint the whole bedroom can be estimated dividing the whole bedroom (1) by this rate. The rate of painting can be calculated as:

R= (1/3 bedroom portion) / (4/5 hour) = 5/12 of bedroom per hour

Then the time will be:

T = 1/R = 1/ (12/5) = 12/5 hours

Answer:

The nominal annual interest rate is 15%.

The effective interest rate is 16.08%.

Step-by-step explanation:

$9,375 = $325 (P/A, i%, 36)(P/A, i%, 36)

= $9,375/$325= 28.846

From compound interest tables, i = 1.25%

Nominal Interest Rate= 1.25 x 12= 15%

Effective rate = (1+ (0.15/36))^36-1=1.004^36-1= 16.08%

Michele wanted to measure the height of her school’s flagpole. She placed a mirror on the ground 48 feet from the flagpole, then
yulyashka [42]
Height of the flagpole = x
distance from flagpole to the mirror = 48 ft
height of Michele = 5 ft
distance from Michele to the mirror = 12 ft

Now, set the proportion.

x/48 = 5/12
48 * x/48 = 5/12 * 48
x = 240/12
x = 20

So, the height of the flagpole is 20 ft.

HOPE THIS HELPS!!!!
