7n-22 is more than or equal to 64 what is n

1 answer:

8 0

7n-22 ≥ 64

1. Move constant to the right.

7n ≥ 64 + 22

2. Combine like terms.

7n ≥ 86

3. Divide 7n by 7 to get n alone.

n ≥ 86

4. Divide 86 by 7.

n ≥ 86 / 7 OR n ≥ 12.29

At track practice,Sheila worked on the long jump. Her first jump measured 3 yards, 2 feet, 8 inches. Her second jump measured 2

The length is 19.5 feet. this is because when you add the yards, it equals 15 feet. Next, add 1 + 2 feet from the first and second jump. 10+8 inches equal 1.5 feet. Next, add 15 feet+3 feet+1.5 feet to get 19.5 feet.

serg [7]

Answer:

Length = 2w

Width= w

2w times w= 241

2W^2=241

Divide by 2

W-^2=121

Sq rt each side

W-= 11 cuz 11 times 11=121

Hi there!

$\large\boxed{h = \frac{15x}{y}}$

Recall the volume of a pyramid is:

V = 1/3(bh)

We are given the volume and side length of the base. Find the area of the base:

A = s²

A = (5xy²)² = 25x²y⁴

Plug in the solved for base:

125x³y³ = 1/3(25x²y⁴)h

To isolate for h, begin by multiplying both sides by 3:

375x³y³ = (25x²y⁴)h

Divide both sides by 25x²y⁴. Use the following exponent property:

xᵃ / xᵇ = xᵃ⁻ᵇ

Thus:

375x³y³ / 25x²4⁴ = 15x/y.

The height must be equal to:

$h = \frac{15x}{y}$
