Sliva [168]

Answer:

The total amount that he would have paid after 3 years is $1183.

Step-by-step explanation:

We would apply the formula for determining simple interest which is expressed as

I = PRT/100

I represents interest paid on the amount owed.

P represents the principal or initial amount owed.

R represents interest rate

T represents the duration for which the amount was owed in years.

P = $795

R = 16.25

T = 3 years

I = (795 × 16.25 × 3) ÷ 100

I = $388

Total amount that he would have paid after 3 years is $795 + $388 = $1183

In the accompanying diagram, parallelogram ABCD has
Taya2010 [7]

Answer:

The area of the paralellogram is 24 square units.

Step-by-step explanation:

Geometrically speaking, the area of the parallelogram has an equation equivalent to the area formula for a rectangle, that is:

A = b\cdot h (1)

Where:

A - Area.

b - Base.

h - Height.

The base and height of the parallelogram are, respectively:

Base

b = 8-2

b = 6

Height

h = 5-1

h = 4

Then, the area of the parallelogram is:

A = (6)\cdot (4)

A = 24

The area of the paralellogram is 24 square units.

Can someone help me please
Anastaziya [24]

The first step to solve this problem is to compute first for the area of the bigger rectangle:

A = LW

A = 12m (10m)

A = 120 m^2

Next step is to find the area of the smaller rectangle:

A = LW

A = 7m (2m)

A = 14 m^2

The last step is to deduct the area of the smaller rectangle to the area of the larger rectangle:

Area of larger rectangle – Area of the smaller rectangle = Area of the shaded region

120 m^2 – 14 m^2 = 106 m^2

Therefore, the area of the shaded region is 106 square meters.

….."………….."……how do u do dis?
raketka [301]

Answer:

x = -25

Step-by-step explanation:

3 -  \frac{x}{5}  = 8

5(3 -  \frac{x}{5} ) = 5 \times 8

5 \times 3 - 5 \times  \frac{x}{5}  = 5 \times 8

15 - 5 \times  \frac{x}{5}  = 40

15 - x = 40

- x = 40 - 15

- x = 25

x =  - 25
