Two numbers are between 20 and 30. their greatest common factor is 4.Which two numbers could they be?

Andrew [12]

24 and 28
These are the only two numbers (other than 20 itself) that have a factor of 4. And if you were to find all of their common factors, 4 would be the greatest!

What is the length of the line segment with endpoints (11, −4) and (−12, −4

RUDIKE [14]

Answer:

23 units

Step-by-step explanation:

Use the distance formula: d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

Plug in the 2 points:

d = $\sqrt{(-12 - 11)^2 + (-4 + 4)^2}$

d = $\sqrt{529}$

d = 23

So, the distance is 23 units

If a paper plane is thrown from the top of a 147-foot cliff into the water below, the height of the plane at any given time can

sasho [114]

Answer:

c. 6.5 seconds.

Step-by-step explanation:

We have been given that a a paper plane is thrown from the top of a 147-foot cliff into the water below, the height of the plane at any given time can be determined by the formula $h = -3t^2+147$ , where h is the height of the plane at t seconds.

To find the time, when plane will be at a height of exactly 20.25 feet, we will substitute $h=20.25$ in our given formula and solve for t as:

$20.25= -3t^2+147$

$-3t^2+147=20.25$

$-3t^2+147-147=20.25-147$

$-3t^2=-126.75$

$\frac{-3t^2}{-3}=\frac{-126.75}{-3}$

$t^2=42.25$

Take square root of both sides:

$t=\pm \sqrt{42.25}$

$t=\pm 6.5$

Since time cannot be negative, therefore, the plane will be at a height of exactly 20.25 feet after 6.5 seconds and option 'c' is the correct choice.

What is the length of MN

rusak2 [61]

Answer:

C. 5

Step-by-step explanation:

∆LMN kid an isosceles triangles because it has two base triangles that are equal to each other. Therefore, the sides opposite the base triangles would also be equal to each other.

Thus:

3x = x + 10

Solve for x. Subtract x from each side

3x - x = 10

2x = 10

Divide both sides by 2

x = 5
