Answer:

33600

Step-by-step explanation:

256 ft² wood will be needed for 4 props.

The area is the space occupied by a two-dimensional flat surface. It is expressed in square units. The surface area of a three-dimensional object is the area occupied by its outer surface.

According to the figure,

The lengths are

= (5ft +8ft +7ft +2ft +3ft +5ft) x 2 x 4

= 32 x 2 x 4

= 256 ft²

Thus, 256 ft² wood will be needed for 4 props.

Answer:

390m^2

Step-by-step explanation:

The Surface Area of a triangular prism is L(s1 + s2 + s3) + 2*base area

a = 5m

b = 12m

c = 13m

L = 11m

First, we need to find the base area...

base area = (a*b)/2

(5*12)/2 = 30 m^2

Next, find the surface area

A = 11(5 + 12 +13) + 2*30 = 390 m^2

Answer: y = -4x + 60

Step-by-step explanation:

we can use a simple linear equation to write this problem:

y = mx + b

The slope is given to be the number of bulbs in each pack, which is 4.

now we have: y = 4x +b

The value of b is the y intercept, or the starting value, 60. From this value, 4x can be subtracted to show our remaining bulbs in stock:

y = 60 - 4x

Writing this in the form y = mx+b gives us the equation:

y = -4x + 60

Answer:

y = 4x

Step-by-step explanation:

A corner store sells 60-watt bulbs in pack of 4.

x = number of packs

y = number of bulbs

y = 4x

Check your answer using the problem:

60 = 4x

/4     /4

12 = x

This means that there are 12 bulbs in each pack.

Answer:

264 hours

Step-by-step explanation:

there are 7 days in a week + 4 is 11

11 x 24 (HOURS IN A DAY) = 264 hours

hope this helps

Answer:

264 hours

Step-by-step explanation:

1 week = 7 days

1 day = 24 hours

Therefore, 7 · 24 = the number of hours in a week.

24 · 7 = 168

There are 168 hours in a week.

1 day = 24 hours

4 days = ? hours

4 · 24 = the number of hours in 4 days

24 · 4 = 96

There are 96 hours in 4 days.

You add 168 and 96 hours to get the total number of hours.

168 + 96 = 264

Answer:

207.35"

Step-by-step explanation:

Answer:

165° & 15°

Step-by-step explanation:

Let the first angle be 'a'

second angle be (a-150°)

a+(a-150°) = 180°

2a=180°+150°

2a=330°

a=330/2

a=165°

first angle is 165°

second angle is 165-150=15°

Answer:

15.21= 15.2 when rounded

Step-by-step explanation:

the formula for finding the area of a circle with the diameter is
A= 1/4 × π ×d^2

Answer:

15.21

Step-by-step explanation:

In order to find the area, you must find the radius first.

The diameter (4.4) divided by 2 = radius (2.2)

The area of a circle is pi times the radius squared ([tex]A = \pi r^{2}[/tex]).

In this situation, r, or radius =2.2.

[tex]A = \pi 2.2^{2}[/tex]

[tex]\pi[/tex][tex]2.2^{2}[/tex]= the area, 15.2053084434.

By rounding to the nearest hundredth, you get 15.21. The second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

Answer: 2, 8, 96cm^2, 35 miles

What we know:

How to solve:

    By using our knowledge of ratios and substitution, we can solve these problems.

First problem

Set up ratio                                                             7.5:15

Find GCF                                                                (7.5:15)/7.5

Simplify                                                                   1:2

Solution:                                                                  2  

Second problem

Set up equation                                                     (x/10) = (6/7.5)

Rewrite                                                                   (x/10) = (60/75)

Simplify                                                                   (x/10) = (4/5)

Common denominator                                          (x/10) = (8/10)

Isolate variable                                                      [(x/10) = (8/10)]*10

Simplify                                                                    x = 8

Solution:                                                                  8

Third Question

where x represents the new width, y represents the new length, and A represents the new area.

Set up equation                                                    A = xy

Substitute                                                              A = (2*4)(2*6)

Simplify                                                                  A = (8)(12)

Simplify                                                                  A = 96

Solution:                                                                96 cm^2                                                      

Fourth Question

Where x represents the unknown length in miles

Set up equation                                                    (21:3) = (x:5)

Rewrite in fraction form                                        [(21/3)] /3 = (x/5)

Simplify                                                                   (7/1) = (x/5)

GCF                                                                        5(7/1) = (x/5)

Isolate variable                                                       [(35/5) = (x/5)]*5

Solution:                                                                  35 miles = x

Problem 1:

If the scale factor is 2, then the area of a square with the side measurement of 7.5 units should be (due to areas being squared) 1/2^2 of the square with the side measurement of 15 units. Let's solve this:

(1/2^2)(15*15) = (7.5*7.5)

(1/4)(15^2) = (7.5^2)

225/4 = 56.25

56.25 = 56.25

Therefore, a scale factor of 2 is correct.

Problem 2:

If x = 8, then 8/10 should equal 6/7.5. Let's solve this:

when x = 8:

8/10 = 6/7.5

0.8 = 0.8

Therefore, x = 8 is a correct solution.

Problem 3:

If a scale factor of 2 creates the new area of 96 cm^2, then the old area of (6*4) should be (due to areas being squared) 1/2^2 of the new area. Let's solve this:

(1/2^2)(96) = (6*4)

(96/4) = 24

24 = 24

Therefore, the new area is 96 cm^2.

Problem 4:

If the houses are 35 miles apart, then 3 in./21 mi. should be equal to 5 in./35 mi. Let's solve this:

(21/3) = (35/5)

7 = 7

Therefore, the houses are 35 miles apart.

Answer:

400 tiles

Step-by-step explanation:

40 x 400/100 = 160

Volume = length x width x height

This formula can be used to find the number of cubes as well as the volume.

Number of Cubes: 36

3 x 4 x 3 = 12 x 3 = 36

Volume of One Cube: 1/64 cm^3

1/4 x 1/4 x 1/4 = 1/64

Volume of the Solid: 9/16 cm^3

Length = 1/4 + 1/4 + 1/4 = 3/4

Width = 1/4 + 1/4 + 1/4 + 1/4 = 1

Height = 1/4 + 1/4 + 1/4 = 3/4

3/4 x 1 x 3/4 = 9/16
