1 answer:

7 0

Important variables to know:

I = interest
P = principal (investment)
R = simple interest rate
T = years

Formula: I = PRT

What information do we have?
I = $960
P = $4000
T = 3 years
R = ?

Plug into formula:

960 = 4000(3)(R)
960 = 12000R
R = 960/12000
R = .08

A. $4000 + $960 = $4960. (A= P+ I)
B. 8% (.08)

Part 2: 1080 = 4000*.09*3
A = 5080 - 4960 =$420.

Answer:

$1,605\ ft^{2}$

Step-by-step explanation:

step 1

Find the area of the garden space

First convert mixed number to an improper fraction

$10\frac{5}{6}\ ft=\frac{10*6+5}{6}=\frac{65}{6}\ ft$

$A=\frac{65}{6}*18=195\ ft^{2}$

Mathius walked ⅜ mile to school. Eva walked ⅖ mile to school. How many more

zalisa [80]

Answer:

132ft

Step-by-step explanation:

Mathius Distance = 3/8 mile

Eva Distance = 2/5 mile

1 mile = 5,280ft

1. Start by multiplying the mile distance of Mathius to the distance of 1 mile in feet.

5,280ft x 3/8 = 15840ft/8 = 1980ft

2. Do the same thing as number 1 but for Eva's distance now.

5,280ft x 2/5 = 10560ft/5 = 2112ft

3. Subtract Eva's Distance from Mathius' Distance for the answer.

2112ft (Eva) - 1980ft (Mathius) = 132ft
