Answer:

4=0

Step-by-step explanation:

Simplifying

(-9p + 7) + -1(-9p + 3) = 0

Reorder the terms:

(7 + -9p) + -1(-9p + 3) = 0

Remove parenthesis around (7 + -9p)

7 + -9p + -1(-9p + 3) = 0

Reorder the terms:

7 + -9p + -1(3 + -9p) = 0

7 + -9p + (3 * -1 + -9p * -1) = 0

7 + -9p + (-3 + 9p) = 0

Reorder the terms:

7 + -3 + -9p + 9p = 0

Combine like terms: 7 + -3 = 4

4 + -9p + 9p = 0

Combine like terms: -9p + 9p = 0

4 + 0 = 0

4 = 0

Solving

4 = 0

Look at the formula for the volume of a cylinder below.

scZoUnD [109]

$h = V / ( \pi r^2)$

Okay, so we already have the volume equation for a cylinder here.
$V = \pi r^2 h$
Since we need to find the height(h), we need to basically isolate it in the equation. To do that we just have to divide both sides by (pi * r^2), where we end up with:
$V / (\pi r^2) = h(\pi r^2) / (\pi r^2)$
then
$V / ( \pi r^2) = h$
$h = V / ( \pi r^2)$

Ean: jenny wants to make three pillow cases using fourteen feet of fabric. She plans to use an equal amount of fabric for each p

Veseljchak [2.6K]

Answer:

Approximately 4.67 feet of fabric is required for one pillow case.

Step-by-step explanation:

We are given the following in the question:

Number of pillow cases to be made by Jenny = 3

Amount of fabric Jenny has = 14 feet

Each pillow case use same amount of fabric.

Amount of fabric used to make 1 pillow case =

$=\dfrac{\text{Amount of fabric}}{\text{Number of pillow cases}}\\\\=\dfrac{14\text{ feet}}{3}\\\\\approx 4.67\text{ feet}$

Thus, approximately 4.67 feet of fabric is required for one pillow case.

loris [4]

Answer:

4 cm

Step-by-step explanation:

Both the area of a square and the area of a rectangle can be found by multiplying length x width. Because all of the sides of a square are equal, you get 64 when you multiply two sides together to find the area.

Since the rectangle has the same area as the square, that means the rectangle's width has to be a number that equals 64 when multiplied by 16.

So, 64/16 equals 4.

. If Henry plays both games conservatively (CC), find the probability that Henry will earn

larisa86 [58]

Answer:

a) 2/2 + 2/2 = 2

b) 2/2 + 1/2 = 3/2

c) 2/2 + 0/2 = 1

d) 0/2 + 0/2 = 0

Step-by-step explanation:

a) 2 points : 2/2 + 2/2 = 2

if henry wins both games than we get probability =2

b) 1 1/2 or 3/2 : 2/2 + 1/2 = 3/2

if henry wins one game and tie another game we get probability =3/2

c) 1 point: 2/2 + 0/2 = 1

if henry wins one game and loose second game, we get probability 1

d) 0 points: 0/2 + 0/2 = 0

if henry loose both games we get probability 0
