A protein mix claims to contain a bonus of 20% more mix than the usual size container. If the bonus size contains 18 ounces of m
agasfer [191]

Answer:

The usual size of the container is 15 ounces.

Step-by-step explanation:

Consider the provided information.

A protein mix claims to contain a bonus of 20% more mix than the usual size container.

Let the usual size of the container was x ounces.

They increase 20% of usual size and the bonus size is 18 ounces.

Therefore, the new size should be:

x+20\%x=18

x(1+0.20)=18 (∴20%=\frac{20}{100}=0.20)

x(1.20)=18

x=\frac{18}{1.20}

x=15

Hence, the usual size of the container is 15 ounces.

1 minute after 4 minutes, when the temperature is 35 °C, we expect it to be 2.5 °C higher, or 37.5 °C.

Find the slope of the line passing through each of the following pairs of points and draw the graph of the line. (5, 2), (3, 3)
Strike441 [17]

Answer:

-0.5

Step-by-step explanation:

  • slope=rise/run or y/x in other words(y2-y1/x2-x1)
  • (y2-y1) is 3-2 so y2-y1=1
  • (x2-x1) is 3-5 so x2-x1= -2
  • -1/2 or -0.5 would be the slope.
