Mike was in charge of a special sports day at the Community Center. A company donated 50 boxes of ice cream bars, with 12 bars i

Anna007 [38]

The right answer is Option D.

Step-by-step explanation:

Boxes of ice cream received = 50

Ice-creams in each box = 12

Total ice-cream bars = No. of boxes * Ice cream bars in each box

Total ice-cream bars = $12*50=600$

No. of people who had ice cream bars = 520

Ice-cream bars left = Total ice cream bars - No. of people who had ice cream

Ice cream bars left = $600-520=80$

80 ice cream bars were left.

The right answer is Option D.

Bob believes his test grade varies directly with the number of hours he spends studying and inversely with the number of hours h

Readme [11.4K]

Answer: Hello mate!

A direct variation implies that, if y is the dependent variable that varies with the variable x; then: y = k*x where k is a real number.

An inverse variation has the form y = k/x where also k is a real number.

them, if we define s as the hours that Bob spends studying, and b as the hours that he spends playing baseball, then the equation that represents the score is:

Score(s,b) = k*s/b

we know that if s = 6, and b = 7, then the score is 72; with this information, we could obtain the value of the constant k.

score(6,7) = 72 =k*6/7 = k*

then k = 72*(7/6) = 61.7

now if s = 4 and b = 6, the score that he should expect is:

score( 4, 6) = 61.7*(4/6) = 41
