Consider that a 1/2 cup serving of 1% cottage cheese is equivalent to 125 grams. If 1 ounce of cottage cheese is equivalent to 2
VikaD [51]

Answer:

4.42 ounces.

Step-by-step explanation:

We have been given that a 1/2 cup serving of 1% cottage cheese is equivalent to 125 grams. 1 ounce of cottage cheese is equivalent to 28.35 grams.  We are asked to find the ounces in 1/2 cup serving.

We will use proportions to solve our given problem.

\frac{\text{Ounce}}{\text{Grams}}=\frac{1}{28.25}

Upon substituting our given values, we will get:

\frac{\text{Ounce}}{125}=\frac{1}{28.25}

\frac{\text{Ounce}}{125}\times 125=\frac{1}{28.25}\times 125

\text{Ounce}=4.42477876

Upon rounding to nearest hundredth, we will get:

\text{Ounce}\approx 4.42

Therefore, 1/2 cup serving contains 4.42 ounces.

Please help!!!! D:<br>(word problem grade 7-8)​
KIM [24]

Answer:

1

Step-by-step explanation:

To solve this, first, take 22 minutes and divide it by 60 minutes, which is the number of minutes in an hour. Then, add two to the value, and multiply it by six square meters per hour, which is the rate that David can paint the wall. From there, you get 14.2 square meters which he painted in 2 hours and 22 minutes. Divide 14.2 square meters by the length of 11 meters to get 1.290 meters. Since they asked you to round to the nearest meter, you get 1 meter.

MariettaO [177]

Answer:

b 19.2

Step-by-step explanation:

a = \pir^{2} for a circle.  We do not want to find the area for a whole circle.  We only want to find the area for part of a circle.  a hole circle is 360 degrees.

a = \frac{88}{360}\pir^{2}

a = \frac{88}{360}\pi(5^{2})

a = 19.2 rounded.
