perimeter- 5+4+6+6+2+5 = 28

area- (1/2(4)(3)) +(6·5) = 36

perimeter- 1+4+3+5+10 = 23

area- (1·5)+(3·10) =35

If x represents Chloe’s weekly sales, she will earn more money with Option 1 when

Answers

1) $600 with option 1 or (3200)(.08) +350, 256+350= $606 with option 2, so option 2 is more money
2) for option one the equation is y=600, for option 2 the equation is y= 0.08x + 350
3) Chloe will earn more with option 1, when her weekly sales are less than $3125

Chloe will earn more money with option 1

2.4n + 1.2n - 0.12 = 7.08

Answers

Answer:

n=2

Step-by-step explanation:

Answer:

The answer is n=2.

Step-by-step explanation:

First, combine like terms, so the problem then looks like 3.6n-0.12=7.08.

Then, add 0.12 to both sides, which now looks like 3.6n=7.2.

Finally, divide both sides of the equation by 3.6, and the final answer is n=2.

a ramp measures 6 feet long. if the ramp is 12 inches tall, what is the horizontal distance it covers? i'll give brainliest to whoever answers first/correctly!

Answers

Answer:

nothing

Step-by-step explanation:

nothing

Answer:

1 ft is equals to 12 in

the ramp is 12 inches tall 1 ft tall

A ramp measures 6 ft long

applying the Pythagorean theorem

c²=a²+b²

where

c =6 ft long

a = horizontal distance

b = 1 ft tall

[tex]a^2= c^2 -b^2 = 36 -1 =35\\a=\sqrt{35}=5.92ft[/tex]

7th grade math pls help me

Answers

Answer:

I think the answer might be true

Step-by-step explanation:

Supplementary angles add up to 180 degrees. When the angles are placed next to each other, they should add up to 180. Let's try it... 130+50 = 180. Therefore, these angles are supplementary.

Also, for extra help, 180-degree angles make a straight line, like this one. When you get stuck, you can always refer to websites such as Khan Academy for practice and explanations. (https://www.khanacademy.org)

Here is the question!: Find the surface area of the following triangular prism.

Answers

Answer:

[tex]336\:\mathrm{ft^2}[/tex]

Step-by-step explanation:

The total surface area simply consists of three rectangles and two triangles. To find the total surface of the figure, find the sum of each of the shapes that make up the outside of the figure:

2 triangles: 2 x 1/2 x 6 x 8 = 48 ft^2

First rectangle: 6 x 12 = 72 ft^2

Second rectangle: 8 x 12 = 96 ft^2

Third rectangle: 10 x 12 = 120 ft^2

*Note: One of the dimensions is in yards, so make sure to convert it to ft (1 yd = 3ft)

Thus, the total surface area of the figure is 48+72+96+120 = 336 ft^2.

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results.

Students

Teachers
A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9.
