Answer:

146 ft²

21.6 tiles

1.8 boxes

Step-by-step explanation:

Please find attached an image of the family room used in answering this question

the family room has the following shapes : 2 triangles and one rectangle

the area of the family room can be determined by calculating the area of each of the shape and adding the 3 areas together

area of a rectangle = length x breadth

16 x 7 = 112 ft²

Area of a triangle = 1/2 x base x height

Area of the smaller triangle = (1/2) x 4 x 3 = 6 ft²

Area of the bigger triangle = (1/2) x 8 x 7 = 28 ft²

Sum of the areas = 112 + 6 + 28 = 146 ft²

b.

1. First convert the area of the room to inches

1 ft = 12 in

146 x 12 = 1752 in²

2. the next step is to determine the area of the tile

area of a square = length²

9² = 81 in²

3. Divide the area of the room by the area of the tile

1752 / 81 = 21.6 tiles

c. total number of boxes that would be bought = 21.6 /12 = 1.8 boxes

Answer:

0.7

Step-by-step explanation:

Answer:

the answer is 2.25

Step-by-step explanation:

Answer:

2.25

Step-by-step explanation:

Answer: 14.25 ft

Step-by-step explanation:

Assuming all the bricks used are red:

Keith puts 19 bricks end to end along a sidewalk and each one of those bricks is 0.75 ft long.

When put end to end therefore, the total length will be that length multiplied by the number of bricks laid:

Total length = Number of bricks laid * Length of each brick

= 19 * 0.75

= 14.25 ft

The number of years value isn't given, we could use an hypothetical value, which can be substituted for the correct number of years given in your exercise in other to find the exact answer.

Using a t value of 10 years

Answer:

651558

Step-by-step explanation:

Given that:

Initial population, P0= 400,000

Growth rate, r = 5%

Using the relation :

P(t) = P0 * (1 + r)^t

t = number of years = 10

P(10) = 400000 * (1 + 0.05)^10

P(10) = 400000 * (1.05)^10

P(10) = 400000 * 1.628894626777

P(10) = 651557.8507

= 651558 nearest whole number.

Recall that, the t value used is hypothetical and should be replaces with te exact value given in your question.

Answer:

The other angle is 155°.

Step-by-step explanation:

Supplementary angles are two angles that have a sum of 180°.

I found my answer my subtracting 25 from 180 (180-25) and my difference was 155.

And, 155 + 25 = 180°.

Therefore, the other angle is 155°.

Answer:

either 81 or 162

Step-by-step explanation:

I got 81 by 27×12

162=27×12×2

Answer:

It seems that you are trying to find the length of hair of Florencia on Tuesday.

Given that length of the hair of Florencia on Monday = h centimeters

On Tuesday, she got hair cut.

So new length of the hair of Florencia on Tuesday = 75% of Monday value

= 75% of (h)

= 0.75* (h)

= 0.75h

Hence final answer is the length of the hair of Florencia on Tuesday is ( 0.75h ) centimeters.

Answer:

3/4h and 0.75h

simply divided by 4 :)

Answer:

The solution is (-2,-2)

Step-by-step explanation:

This is the point where the two graphs intersect.

120 ÷ ( 3 + 5 ) = 120 ÷ 8 = 15

15 × 3 = 45

15 × 5 = 75

_________________________________

Answer:

15:75

Step-by-step explanation:

120 = 3x plus 5x

120 = 8x

120/8 = x

x = 15

3*15 = 45 and 5*15 = 75

Answer: In percentage, the answer is 115%

Step-by-step explanation: if you want to find the rise, just simply divide 5500 from 6325, or 6325/5500. You will get 1.15 but converted to percentage, that is 115%

Answer:

[tex]12g+44h[/tex]

Step-by-step explanation:

Step 1: Rearrange terms

[tex]4(11h+3g)\to4(3g+11h)[/tex]

Step 2: Distribute

[tex]4(3g+11h)\to12g+44h[/tex]

Answer:

44h+12g

Step-by-step explanation:

Okay, so, this a standard algebraic expanding problem, so:

We take our 4(11h + 3g)

because we have parenthesis, we have to distribute the 4:

4 x 11h + 4 x 3g = 44h + 12g

So, 4(11h + 3g) expanded is 44h + 12g

Answer:

x= −20

Step-by-step explanation:

Let's solve your equation step-by-step.

−3(x+9)=33

Step 1: Simplify both sides of the equation.

−3(x+9)=33

(−3)(x)+(−3)(9)=33(Distribute)

−3x+−27=33

−3x−27=33

Step 2: Add 27 to both sides.

−3x−27+27=33+27

−3x=60

Step 3: Divide both sides by -3.

−3x −3 = 60 −3 x=−20

Answer:

x=−20

Hope this helps! :)

Answer:

x=-20

Step-by-step explanation:

−3(x+9)=33

Divide both sides by -3

-3(x+9)/-3=33/-3

simplify;

-3(x+9)/-3

Divide the numbers:3/3=1

=x+9

Simplify 33/-3

=-33/3

Divide the numbers 33/3

=-11

x+9=-11

Subtract 9 from both sides

x+9-9=-11-9

Simplify;

x=-20
