Answer:

V = 125 in^3

Step-by-step explanation:

A cube has 6 sides, and the area of each is equal to the side length squared:

A = 6x^2

A is given as 150 cm^2, and so is equal to 6x^2. Thus, x = the side length = 5 cm.

The volume of the same cube is given by V = x^3, which here is 5^3 in^3, or V = 125 in^3

Help me please it urgent i have homework anyone there

Andru [333]

Answer:

14.9g + 9.5c

Step-by-step explanation:

g stands for $ earned training & c stands for $ earned working with customers

Anthony trained for 8.5 hours so, 8.5 hours x g $ earned at training = 8.5g

He worked with customers for 4.3 hours, so 4.3 hours x c $ earned with customers = 4.3c

Anthony's total $ earned is 8.5g + 4.3c

Madison trained for 6.4 hours so, 6.4 hours x g $ earned at training = 6.4g

She worked with customers for 5.2 hours, so 5.2 x c $ eared with customers = 5.2c

Madison's total $ earned is 6.4g + 5.2c

Anthony 8.5g + 4.3c

Madison 6.4g + 5.2c

If you add both their $ earned training, you get 14.9g

If you add both their $ earned with customers, you get 9.5c

To total what they both earn it would be 14.9g + 9.5c

Solve for y. Round your answer to the nearest tenth and explain all steps. -3=15+4y

LUCKY_DIMON [66]

Answer: y = -4.5

Step-by-step explanation:

Given expression

-3 = 15 + 4y

Subtract 15 on both sides

-3 - 15 = 15 + 4y - 15

-18 = 4y

Divide 4 on both sides

-18 / 4 = y / 4

$\boxed{y=-4.5}$

Hope this helps!! :)

If Bill bought a home for $210,000 and he sold it a year later for $120,000 his percentage of loss is

Greeley [361]

Answer:

Bill suffered a loss of 42.85%.

Step-by-step explanation:

Bill bought a home for $210000 and sold it for $120000 and we have to calculate the percentage loss he suffered.

As we know loss suffered = Difference of sale price and cost price of the home.

Total loss = 210000-120000 = $90000

Now percentage loss = $\frac{Total Loss }{cost price}.(100) = \frac{9000}{210000}.(100)$

= 9/21×100 = 3×100/7 = 42.85%

So the answer is 42.85% loss.
