Emily wants to buy a car. She pays a deposit equal to 20% of the cost of the car. She will pay the balance in 8 equal payments o

olga55 [171]

Answer: the cost of the car is $54600

Step-by-step explanation:

Let x represent the cost of the car.

She pays a deposit equal to 20% of the cost of the car. This means that the amount of money that she paid as deposit would be

20/100 × x = 0.2 × x = 0.2x

The remaining balance would be

x - 0.2x = 0.8x

She will pay the balance in 8 equal payments of $5460 each month. This means that

0.8x/8 = 5460

0.1x = 5460

Dividing the left hand side and the right hand side of the equation by 0.1, it becomes

0.1x/0.1 = 5460/0.1

x = 54600

Given is triangle with base = 10 cm and perpendicular height = 3 cm.

We know the formula for area of triangle is given by :-

Area = $\frac{1}{2}$ × (Base) × (perpendicular height)

Area = $\frac{1}{2}$ × (10) × (3)

Area = $\frac{30}{2}$

Area = 15 cm²

So, final answer is 15 cm².

Please, I give 20 score. Find the volume

Elza [17]

Answer:

2388.16 in³

Step-by-step explanation:

1) find volume of cylinder

formula: πr²h

given:

π = 3.14

r = 8/2 = 4 in

h = 9 in

$\pi \: r {}^{2} h$

$(3.14) \times (4 {}^{2} ) \times 9$

$3.14 \times 16 \times 9$

$452.16 \: {in}^{3}$

2) find volume of cuboid

formula: length × width × height

given:

length = 16 in

width = 11 in

height = 11 in

$l \: \times w \: \times h$

$16 \times 11 \times 11$

$1936 \: in {}^{3}$

total volume of figure

= volume of cylinder + volume of cuboid

= 452.16 in³ + 1936 in³

= 2388.16 in³
