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.

Negative square root of nine is it a rational or irrational number

Sergio [31]

It's a rational number. 9 is a perfect square. What you have asked is written as -sqrt(9), which can be written as -sqrt(3*3) which is - 3. That's perfectly OK. What would not be OK is something like -sqrt(10) which is irrational because it cannot be represented as a fraction or a whole number or a repeating decimal or a decimal that terminates.

What is 3 = 5x - 12?

zepelin [54]

Answer:

x = 3

Step-by-step explanation:

3=5x-12

Rearrange the Equation.

5x - 12 = 3

Add 12 to both sides.

5x - 12 + 12 = 3 + 12

Simplify

5x = 15

Divide both sides by 5

5x/5 = 15/5

x = 3
