A student has a 90, 84, and an 86 on their first 3 tests. What possible scores would the student need

Ugo [173]

The student would have to score 100% on their next test to brung their average up to 90. Here is why;
90+84+86=260
(260+?)/4=90
(260+100)/4=90
360/4=90
This is done to get the mean (or average) of a group of numbers by adding all the numbers and dividing by the amount of numbers you added together. Here it is divided by 4 because of the three tests he has taken and the test he will take.

tangare [24]

Answer:

Part a) The total volume is $98\ ft^{3}$

Part b) $84\ ft^{3}$

Step-by-step explanation:

Part a)

Find the total volume

we know that

The volume of a rectangular prism is equal to

$V=LWH$

we have

$L=3\frac{1}{2}\ ft=\frac{3*2+1}{2}=\frac{7}{2}\ ft$

$W=3\frac{1}{2}\ ft=\frac{3*2+1}{2}=\frac{7}{2}\ ft$

$H=8\ ft$

substitute in the formula

$V=(\frac{7}{2})(\frac{7}{2})(8)=98\ ft^{3}$

Part b) If they are only going to fill the dunking booth 6/7 full, how many cubic feet of water will they need?

Multiply the total volume by 6/7

so

$98(6/7)=84\ ft^{3}$
