Answer:

division

Step-by-step explanation:

you'll have to get rid of the 3 so that we can get the value of x. in other words the value of 3 xs is 81, but we need the value of only 1 x, which is why we're gonna divide both sides by 3. to get the value of only 1 x.

hope i helped :))

pantera1 [17]

Answer:

V ≈ 226.72 cm³

Step-by-step explanation:

Use the formula for volume of a cone using slant height and radius.

V = 1/3 π r² √ l² - r²

Then, plug in dimensions and solve.

V = 1/3 π (10)² √ 10² - 5²

V ≈ 226.72 cm³

Hope I could help!!! Good luck!!!

Assume that the notation (a,r,s,t) means multiply q and r, then add the product to s and (2,6,4,8)+(4,7,2,6)? Please show work a

<h3>Answer:  7.0   (choice E)</h3>

=============================================

Work Shown:

\perp (q,r,s,t) = \frac{qr + s}{t}\\\\\perp (2,6,4,8) = \frac{2*6 + 4}{8}\\\\\perp (2,6,4,8) = \frac{12 + 4}{8}\\\\\perp (2,6,4,8) = \frac{16}{8}\\\\\perp (2,6,4,8) = 2\\\\

Let m = 2 so we can use this result later.

\perp (q,r,s,t) = \frac{qr + s}{t}\\\\\perp (4,7,2,6) = \frac{4*7 + 2}{6}\\\\\perp (4,7,2,6) = \frac{28 + 2}{6}\\\\\perp (4,7,2,6) = \frac{30}{6}\\\\\perp (4,7,2,6) = 5\\\\

Let n = 5 so we can use this result later.

Add the two results.

m+n = 2 + 5 = 7.0 is the final answer.

50 POINTS FOR THE CORRECT ANSWER !!!!!!
Stels [109]

Answer:

y = 9.8x + 6.7

y = 6.7x + 9.8

y = 7.5x + 3.8

y = 3.8x + 7.5

Step-by-step explanation:

I made 2represent x.

y= 9.8(2) + 6.7

y = 26.3

y=6.7(2) + 9.8

y= 23.2

y= 7.5(2) + 3.8

y= 18.8

y= 3.8(2) + 7.5

y= 15.1
