Okay so you know a straight line is equal to 180 degrees, so you set them up in an algebraic equation. (5x+2)+48=180 subtract 48 first to get 5x+2=132 Subtract the 2 this time to get 130. Now you end up with 5x=130. Here you divide 130 by 5 to get X=26. If you just need to find the degree of that angle tho you can stop after the first subtraction because the math tells you (5x+2)=132 degrees.

Jackson buys a grape snow cone on a hot day. By the time he eats all the "snow" off the top, the paper cone is filled with 27 pi
Lerok [7]

Answer:

9 cm

Step-by-step explanation:

Use the cone volume formula, V = \pir²\frac{h}{3}

Plug in the volume and radius, and solve for h, the height:

V = \pir²\frac{h}{3}

27\pi = \pi(3²)\frac{h}{3}

27\pi \\ = 9\pi\frac{h}{3}

3 = \frac{h}{3}

9 = h

So, the height of the cone is 9 cm

How is the precision used in measuring the length and width of a rectangle related to the precision of the resulting area measur
steposvetlana [31]
The more precise your length and width are, the more precise your area <span>measurement will be. Take this as example:

</span>width = 9.3045 mm
<span>length = 8.023 mm
</span><span>
Let's first round up:

width = 9.3 mm
length = 8 mm
Area = 9.3*8 = 74.4 mm

But if you are more precise with the width and length:

</span>width = 9.3045 mm
<span>length = 8.023 mm
</span>Area = 9.3045 *  8.023 = <span>74.6500035 mm

The more precise your length and width are, the more precise your area is. Also, as you can see t</span>he more precise your length and width are, the more your area will increase and will be more accurate.<span>

What is 4 2/7 times 2 1/5
IrinaVladis [17]

Hey!

---------------------------------------------------

Steps To Solve:

~Find common denominators

4 2/7 = 4 10/35

2 1/5 = 2 7/35

~Turn into improper fractions

4 10/35 = 150/35

2 7/35 = 77/35

~Multiply

150/35 x 77/35 = 11,550/1,225

~Simplify

11,550/1,225 = 9 525/1,225 = 9 105/245 = 9 21/49 = 9 3/7

---------------------------------------------------

Answer:

9 3/7

---------------------------------------------------

Hope This Helped! Good Luck!
