Answer:

x(3 + 4)

4(3x + 1)

Step-by-step explanation:

3x + 4x

The common factor is x, so factor out the x.

3x + 4x = x(3 + 4)

12m + 4

The common factor is 4, so factor out the 4.

12m + 4 = 4(3x + 1)

Remark

Givens

Circumference = 27.004

pi = 3.14

Formula

C = 2*pi * r

Solution

27.004 = 2 * 3.14 * r

27.004 = 6.28 * r

27.004/6.28 = r

r = 4.3

Answer: 2*200-321+67=56-65? look at the picture

Step-by-step explanation: Hope this help :D

Answer:

-9

Step-by-step explanation:

2 x 200 = 400

400 -321 = 79

79 + 67 = 146

56 - 65 = -9

Please let me know if this helps.

Answer:

8:64

Step-by-step explanation:

1*8 = 8

so if we do the number under 1 (8) times 8 the ratio will be consistent

So 8*8 or 8² is 64

Answer:

336 cm^2

Step-by-step explanation:

Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.

The next one the 6X13  one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.

Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get

336 cm^2

Answer:

-Entire triangle region : 120 sq.cm

-Area of semi circle : 100.53 sq.cm

-Entire composite figure : 220.53 sq.cm

Step-by-step explanation:

Area of triangle = ½ × base × height

= ½ × (8+8) × 15

=½ × 16 × 15

= 120 sq.cm

[tex]area \: of \: semi \: circle = \frac{1}{2} \pi {r}^{2} \\ = \frac{1}{2} \times \pi \times {8}^{2} \\ = \frac{1}{2} \times \pi \times 64 \\ = 32\pi[/tex]

=100.530.......

=100.53 sq.cm (rounded to 2 decimal place)

Area of entire figure = 120 + 100.5353

= 220.53 sq.cm

Hope I could help:))

Answer:

I think it B but I really don't know cause need like an example

The k in the equation represents Option B) The constant of variation

A constant is a value or number that never changes in expression; it's constantly the same. For example,  36 and 82 are constant because its face value is 36 and 82 respectively. Its value never changes.

Given here the equation y=kx where k is the slope and a scalar value thus it is independent of x and y and thus is a constant.

Hence, The k in the equation represents Option B) The constant of variation

Answer:

The percent of change is 22.22%.

Step-by-step explanation:

You can calculate the percent of change by subtracting the original number from the final number and dividing that by the original number. Then, you have to multiply the result for 100:

percent of change=((1,100-900)/900)*100

percent of change=(200/900)*100

percent of change=22.22%

According to this, the answer is that the percent of change is 22.22%.

Answer:

Pictograph

Step-by-step explanation:

Answer:

Steps:

given: m∠EFG = 90°

tan(x) = FG/EF

tan(x) = 10.5/9

tan(x) = 7/6

tan(x) = 1.166..

x = tan⁻¹(x)

x = tan⁻¹(1.166..)

x = 49.39.. ≈ 49.4°

Answer:

28in

Step-by-step explanation:

you cut the face in shapes you recognize how to do the area of. Then find the numbers of the shapes that might be missing, then add them all up.

I see a rectangle, square, and square.

A = 10×2

A = 20in

A = 2x2

A = 4

A = 2x2

A = 4

add the areas up you get 28in
