If 2500 amounted to 3500 in 4 years as simple interest .find the rates at wish the interest was charged

Bad White [126]

Answer:

The interest rate per year is 0.1

Step-by-step explanation:

The equation is A = P(1+rt)

Substitute the numbers

3500 = 2500 (1+4r)

solve for r:

$3500/2500 = 1+4r$

$1.4-1 = 4r$

$0.4 /4 = r$

$r = 0.1$

Marcus is building a fence around his rectangular backyard. The length of his backyard is 75 3/4 ft, and the width is 81 1/4 ft.

Allisa [31]

Answer:

Step-by-step explanation:

Answer:

4,923.75ft²

Step-by-step explanation:

The area of the backyard = Length * width \

Area of the backyard = 75 3/4 * 81 1/4

Area of the backyard = 303/4 * 325/4

Area of the backyard = 6,154.6875ft²

If 3/4 of the fence is finished, the area of the finished part is expressed as;

Finished part = 1/5 * 6,154.6875

Finished part = 1,230.9375ft²

Part left unfinished = 6,154.6875-1,230.9375

Part left unfinished = 4,923.75ft²

Left to Right

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from table.

Point (-1, -1)

Point (0, -5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m. Rate of change and slope are identical.

Substitute [SF]: $m=\frac{-5+1}{0+1}$
Add: $m=\frac{-4}{1}$
Divide: $m=-4$
