What expression is equivalent to 7sqrtx^2/5sqrty^3​
V125BC [204]

Answer:

Step-by-step explanation:

Sounds as tho' possible answer choices were listed.  Please, share them without being asked to do so.  Thank you.

 7√(x²)          7√(x²)

------------- = ----------------------

  5 √(y³)        5√( y^(3/2) )

We want to get the fractional exponent out of the denominator.  To do this, multiply both numerator and denominator by y^(1/2):

 7√(x²)          7√(x²)                y^(1/2)      7√(x²)·y^(1/2)       7x√y

------------- = --------------------- * ----------- = --------------------- = ----------

  5 √(y³)        5√( y^(3/2) )       y^(1/2)        5 √(y²)                  5y

This is the final answer.  We have succeeded in removing radicals / fractional exponents from the denominator.

A charity sent out 700 fundraising letters and received 210 contributions in response. What was the percent of response?
Pavlova-9 [17]
To find the answer, you have to make a proportion. 210 out of 700, or 210/700 is equal to x/100. So, 210/700=x/100. Then to solve the proportion, you must cross multiply. 210 times 100 is 21,000. Then, you must divide 21,000 by 700, which is 30. The 30 represents 30/100, which is 30%
The answer is 30%.
