A square patio has an area of 225 square feet. Write the area as a power.
Then find the side lengths of the patio.

Answers

Answer:
Write the area as a power: 15^2
Then find the sidelength of the patio: Each side is equal to 15

Reasoning:

A square has four equal sides and to work out area the formula is length x witdth, hence the length and width values are equal. This could also be written as length^2.

Since the area of the patio is 225, the square root of this would give each side length. Henceforth the square root of 225 is equal to 15. A square has four equal sides and to work out area the formula is length x witdth, hence the length and width values are equal. This could also be written as length^2.

An equation is shown below: 3(4x + 5) = 12 Which of the following correctly shows the beginning steps to solve this equation?

Answers

Answer:

I believe the answer would be step 1: 12x + 15 = 12, and step 2: 12x = -3.

Step-by-step explanation:

3(4x + 5) = 12, you would foil and do 3 times 4x which is 12x, then do 3 times 5 which is 15. So the result would be 12x + 15 = 12.  And the step 2 that goes along with this answer. you would do -15 on both sides of the equal sign, so now you have 12x = 12 - 15 which is -3, so it would be 12x = -3

Answer:

Step 1 would be the answer: Step 1: 12x + 15 = 12 Step 2: 12x = −3 Step 1: 12x + 5 = 12

∠A and \angle B∠B are complementary angles. If m\angle A=(8x+27)^{\circ}∠A=(8x+27)

and m\angle B=(6x-21)^{\circ}∠B=(6x−21)

, then find the measure of \angle B∠B.

Answers

Answer:

∠ B = 15°

Step-by-step explanation:

Complementary angles sum to 90° , that is

∠ A + ∠ B = 90 , substitute values

8x + 27 + 6x - 21 = 90

14x + 6 = 90 ( subtract 6 from both sides )

14x = 84 ( divide both sides by 14 )

x = 6

Thus

∠ B = 6x - 21 = 6(6) - 21 = 36 - 21 = 15°

Listen i know its dumb but-
solve for w
10 + w = -9

Answers

Answer:

w = -19

Explanation:

To solve this equation, subtract ten from both sides. This will isolate the variable (w) and allow us to find its value.

[tex]10 + w = -9\\(10 - 10) + w = (-9 - 10)\\w = (-9 - 10)\\w = -19[/tex]

If you would like to double check that the variable (w) does in fact equal negative nineteen, substitute the value of the variable in the equation and solve.

[tex]10 + w = -9\\10 + -19 = -9\\-19 = -19 [true][/tex]

Therefore, the value of w in the given equation is -19.

blThe mean height of the corn plants of variety A is 43.8 inches. Interpret the value of the mean in the
situation.

Answers

Answer:

The average inches of the height of the corn plants of variety A is 43.8 inches

Step-by-step explanation:

In mathematics or statistics, the mean refers to the average of numbers.

The mean is estimated by dividing sum of all the numbers by the count of the numbers.

For this question, the mean height of the corn plants of variety A of 43.8 inches is obtained as follows:

Sum of all the inches = 46 + 46 + 47 + 48 + 49 + 49 + 50 + 6 + 48 + 49 = 438 inches

Count of all the inches = 10

Mean = Sum of all the inches / Count of all the inches = 43.8 inches

The interpretation of this is that the average inches of the height of the corn plants of variety A is 43.8 inches.
