don’t understand........

Answers

Answer 1

Answer:

120 cubic inches.

Step-by-step explanation:

The formula for volume is length times width times height. So if you take the length (10), and you take the width (3), and then you multiply them together you get 30. Now all you have to do it multiply that to the height (4) so you get 120. So your answer should be 120 cubic inches.

10 × 3 = 30

30 × 4 = 120

I hope this helps you and you understand now. Have a nice day! :D

Exponents work the same way on bases that are _[blank A]_ as they do on bases that are numbers.

When a variable has an exponent, the exponent tells you how many times the variable is _[blank B]_ by itself.

In order to make a negative exponent positive, you must take the _[blank C]_ of the base.

A variable raised to the power of _[blank D]_ is always equal to 1.

Christina earned $510 working part-time at the movie theater. Of her paycheck, 1/ 4 pays for car insurance, 1/ 3 for gas, and 20% for miscellaneous expenses. The remaining amount of her paycheck is divided equally for entertainment and savings. How much does Christina spend each month on entertainment?

Answers

Answer:

$55.15

Step-by-step explanation:

1/4 of 510 = 127.5

1/3 of 510 = 170

20% of 510 = 102

510-(127.7+102+170)=510-399.7=110.3

110.3/2=55.15

Write the equations of the line that passes through the point 4,3) and is perpendicular to the line y=2x−4 . Write the equation in slope-intercept form.

Answers

Answer:

y = -¹/₂x + 5

Step-by-step explanation:

The product of slopes of perpendicular lines is -1

y = 2x − 4 ⇒ m₁ = 2

m₁m₂ = -1

2m₂ = -1

m₂ = -¹/₂

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is: y - y₁ = m(x - x₁)

m = -¹/₂

(4, 3) ⇒ x₁ = 4, y₁ = 3

So the equation in point-slope form:

y - 3 = -¹/₂(x - 4)

Therefore:

y - 3 = -¹/₂x + 2

y = -¹/₂x + 2 + 3

y = -¹/₂x + 5

A bricklayer lays 1200 bricks in an average 8-hour day. How many bricks does he lay in a 40-hour week?

Answers

The answer is 6000 bricks.
40/8=5
5*1200=6000

The number of bricks that the bricklayer can lay in a 40-hour week is 6000 bricks.

Let the number of bricks that the bricklayer can lay in a 40-hour week be represented by x.

Based on the information given in the question, the equation to solve the question will be:

8/40 = 1200/x

Cross multiply

8 × x = 1200 × 40

x = (1200 × 40) / 8

x = 1200 × 5

x = 6000

Therefore, the number of bricks that the bricklayer can lay in a 40-hour week is 6000 bricks.

In a pet store,the ratio of dogs to cats is 3 to 2. if there are 15 dogs, how many cats are there at the pet store? NEED HELP ASAP

Answers

Answer:

10 cats

Step-by-step explanation:

dogs:cats = 3:2=15:x

3x=15.2

3x=30

x=10 cats

since the ratio is 3:2, you can set up your equation like 3/2 = 15/x. then cross multiply and that will get you 30 = 3x and x will equal 10. this means that there are 10 cats and 15 dogs. hope that helps!
