Answer:

882 cubic ft.

Step-by-step explanation:

10.5 x 10.5 = 110.25

110.25 x 8 = 882 ft

Answer:

the volume of a room = 882 ft³

Step-by-step explanation:

given;

dimensions  of a room 10 1/2 ft. x 10 1/2 ft. x 8 ft.

find:

volume

volume = L x W x H

let L = 10 1/2 ft.

W = 10 1/2 ft.

H = 8 ft.

plugin values into the formula:

V = 10.5 x 10.5 x 8

V = 882 ft³

therefore,

the volume of a room = 882 ft³

Answer:

the answer for x<5

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−4<−4x+16

Step 2: Flip the equation.

−4x+16>−4

Step 3: Subtract 16 from both sides.

−4x+16−16>−4−16

−4x>−20

Step 4: Divide both sides by -4.

25° is the correct answer.

Step-by-step explanation:

(4x+20) +60°=180° [°.° Linear Pairs]

[tex](4x + 20) + 60° = 180°\\ ⟹ 4x + 20 + 60° = 180° \\ ⟹ 4x + 80° = 180° \\ ⟹ 4x = 180° - 80° \\ ⟹x = \frac{100°}{4} \\ ⟹25°[/tex]

Answer:

-5 is an integer.

Step-by-step explanation:

Answer:

it is an integer

Step-by-step explanation:

It's and integer because a whole number goes up higher but never pass 0

an integer has whole numbers and their negative counterparts it would be a whole if it was just 5 and not -5 and it would be rational if it were -5.5

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

M (4, 10) and N(-2,-6)

The midpoint is

[tex]M = ( \frac{4 - 2}{2} , \: \frac{10 - 6}{2} ) \\ = ( \frac{2}{2} \: , \: \frac{4}{2} )[/tex]

We have the final answer as

Answer is option C  

12^2

Thank you

Option C. is correct which represents 12 squared.

Which represents 12 squared.

power is degree of values that is mentioned at the superscript of the value.

12 squared means,

2 superscript to the 12 i.e.

= 12²

Answer:

C

Step-by-step explanation:

Both the given equations are of Perpendicular lines.

Perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).

Given are two equations of lines

y-2= x+20

y = x+20+2

y = x+22.....(i)

y-2= -(x+20)

y = -x-20+2

y = -x-18,,,,,,,(ii)

The slopes of the equation are 1 and -1, We know that perpendicular lines have slopes that are negative reciprocals of one another.

Hence, The lines given are perpendicular lines

Answer:

The answer would be 10^2 or 100.

Step-by-step explanation:

If you take 10^3/10^5 x 10^4 and simplify it, you would get 1/10^ x 10^4. Then you reduce the expression to 10^2, or in alternate form, 100.

Answer:

You use substitution

Step-by-step explanation:

Because you can see that y= both of those answers, you can set them equal to each other, creating the equation 2=x^2-3x-8

You then can use quadratics to solve the equation as follows:

-2 from both sides, 0=x^2-3x-10

Factors of -10 that add up to -3 are -5 and 2 leaving

0=(x-5)(x+2)

The 0 product property tells us that the answer is 5 and -2

To Find :

The slope of line PQ.

Solution :

We know , slope is given by :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{-9-(-7)}{-4-(-1)}\\\\m=\dfrac{2}{3}[/tex]

Therefore, the slope of line PQ is 2/3.

Hence, this is the required solution.

Step-by-step explanation:

Answer:

Perimeter = 28.84 m

Step-by-step explanation:

Since the other two points will make the shape to look like a square, each length of the square will be equal.

We can therefore find the length PQ by using the formula

L = sqrt ( [ X2 - X1 ]^2 + [ Y2 - Y1 ]^2

L = sqrt( [ -2 + 4 ]^2 + [ 4 + 3]^2

L = sqrt (4 + 49)

L = sqrt (52)

L = 7.2 m

Each length of the square is 7.2 m approximately

The parimeters will be:

Perimeter = 4L

Perimeter = 4 × 7.2

Perimeter = 28.84 metres

Therefore, the perimeter of the square is 28.84
