Answer:

1.107 = r

Step-by-step explanation:

To solve this for r, do the following:

Add 10 to both sides, to isolate the r term on the left: 18r^(-8) = 8

Divide both sides by 18, to isolate r^(-8): r^(-8) = 8/18

Invert both sides: r^8 = 9/4

Take the natural log or both sides:

8 ln r = ln 9 - ln 4, or

8 ln r = 0.8109, so that ln r = 0.1014

to find r, raise e to the power ln r on the left and e to the power 0.1014 on the right:

ln r 0.1014

e = e = 1.107 = r

Jon is making hamburgers for a church lunch. He has 42 and two thirds lbs of ground beef. How many one third pound hamburgers ca

lys-0071 [83]

Answer:

He can make 128 one third pound of hamburgers using all the ground beef.

Step-by-step explanation:

Given:

Jon is making hamburgers for a church lunch. He has 42 and two thirds lbs of ground beef.

Now, to find the number of one third pound hamburgers can he make using all the ground beef.

Pound of ground beef he has = $42\frac{2}{3} \ lbs.$

Pound of hamburgers he can make = $\frac{1}{3}$ .

Now, to get the number of hamburgers he can make by using all the ground beef we divide the quantity of ground beef by $\frac{1}{3}$ :

$\frac{128}{3} \div\frac{1}{3}$

As, the division changes into multiplication one of the fraction get reciprocals.

$=\frac{128}{3} \times \frac{3}{1}$

$=\frac{384}{3}$

$=128.$

Thus, 128 hamburgers he can make.

Therefore, he can make 128 one third pound of hamburgers using all the ground beef.
