Answer:
it would take 5 dolls cups
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.
Her fuel tank is not empty. She added 3/4 gallon of fuel and used 2/4 which still leaves 1/4 gallon left. If she had only put 1/2 a gallon, it would have been empty.
Y=2/(x^2 +3)
g(x) = x^2 + 3 and f(x) = 2/x
fog(x) = f[g(x)]
= f(x^2 + 3)
= 2/(x^2 + 3)
The answer is 74,606,800
I you need an equation use 142 million times(multiplication) by 52.54 percent.
I hoped this helped :))
