Answer:

r = -6

Step-by-step explanation:

basically send the letters on one side (preferably the left) of the = sign... and the numbers on the other side. Remember when you pelting things across the equal sign, you have to switch the signs... meaning positive (+) will become negative (-) or vice versa...

6r + 7 = 13 + 7r

6r - 7r = 13 - 7

-1r = 6

r = -6

Round to the nearest tenth wa hit is the perimeter of the triangle
klio [65]

Answer:

D. 11.8 cm

Step-by-step explanation:

This triangle is a 30°-60°-90° triangle. There is a shortcut to find the lengths of the sides of a 30°-60°-90° triangle. The longest side is the hypotenuse. The longest side is double the shortest side or, the shortest side is half the longest side. Here the longest side is 5, so the short leg (shortest side) is 2.5

The other shortcut is that the longer leg is the

short leg×sqroot3

Here, the short leg is 2.5, so the long leg is 2.5×sqroot3

Perimeter is all the sides added together.

5 + 2.5+ 2.5×sqrt3

Do the times first.

5 + 2.5 + 4.3

= 11.8

The  average income:

\to A(x) = \frac{R(x)}{x} =7.5 x^{-0.3}

The change rate on the average revenue:

\to A'(x) =7.5(-0.3)x^{-1.3}

when 81 bottles were produced , then the rate of change in average revenue

\to =A'(81)\\\\\to -0.007  \ / \ bottle
