Homework due at 12:00 I need HELP. Please!!!

Damm [24]

If you are trying to find the surface area I believe it would be 3456 inches. You would do 24 X 24 to get 576 because the formula to get the area is Length times width. Then you would do 576 times 6 because the cube has 6 sides and you would multiply it by the number of sides because each would be the same, cubed are the same length all around. Hope this helped.

Bill drove his car at a constant speed while on a trip. Kevin drove his car at a different constant speed while on the same trip

Step2247 [10]

I thought to say the second sentence because it says that he’s going at a different constant speed but he doesn’t say compared to who... I’m leaning more to the last sentence.
What do you think?

Determine the x intercepts of the piecewise function in the image that I sent.

Amanda [17]

To find the x intercept of the function, we would find g(x) = 0

To do this, we would set each expression in the piecewise function to zero and solve for x. We have

For

x/3 + 2 = 0

let us multiply both sides of the equation by 3. We have

x/3 * 3 + 2 * 3 = 0 * 3

x + 6 = 0

x = - 6

- 6 is less than - 1

- 6 < - 1

It satisfies the inequality. Thus, x = - 6 is in the domain

For

4x - 2 = 0

adding 2 to both sides of the equation, we have

4x - 2 + 2 = 0 + 2

4x = 2

Dividing both sides of the equation by 4, we have

4x/4 = 2/4

x = 1/2

x = 1/2 is less than 1. It is not in the domain of this equation. Thus, there is no x interscept at x = 1/2

Therefore, the x intercept of the piecewise function is (- 6, 0)

20 liters of mixture contain milk nad water in the ratio 5:3 of 4 liters of the mixture are replaced by 4 liters of milk find th

pantera1 [17]

Answer:

7:3

Step-by-step explanation:

5 + 3 = 8

The ratio is

5 milk : 3 water : 8 total

Milk is 5/8 of the total.

Water is 3/8 of the total.

The 20-liter mixture contains:

5/8 * 20 = 12.5 liters of milk, and

3/8 * 20 = 7.5 liters of water

4 liters of the mixture contain:

5/8 * 4 = 2.5 liters of milk, and

3/8 * 4 = 1.5 liter of water

When you remove 4 liters of the mixture from 20 liters of the mixture, you end up with

12.5 L - 2.5 L = 10 L milk, and

7.5 L - 1.5 L = 6 L water

Now you add 4 liters of milk. Now you have

10 L + 4 L = 14 L milk

6 L water

The new ratio of milk to water is 14:6 = 7:3

By definition we have that the area of a regular octagon is:
A = 4.83L ^ 2
Where, L is the length of the octagon side.
the similarity ratio = the area ratio.
We have then:
similarity ratio = (50) / (18) = 25/9.
the ratio of the perimeters
A1 = 4.83L1 ^ 2
L1 ^ 2 = A1 / 4.83
L2 ^ 2 = A2 / 4.83
L1 ^ 2 / L2 ^ 2 = A1 / A2 = 25/9
L1 / L2 = 5/3
The perimeter is:
P1 = 8L1
P2 = 8L2
P1 / P2 = 8L1 / 8L2 = L1 / L2 = 5/3
answer:
similarity ratio:
25: 9
the ratio of the perimeters:
5: 3
