Answer:

Step-by-step explanation:

Let the number of questions be A.

Marissa got 85% on her math quiz and got 34 questions correct.

This Means 85% of the number of math questions =84

Therefore

85% of A = 34

This is

85/100 x A = 34

0.85 x A = 34

Divide both sides by 0.85

0.85/0.85 x A = 34/0.85

A = 40

The number of questions on the quiz was 40

Maddy lleva un bote con bebida para deportistas; el bote de 5 55 litros pesa 7 , 5 kg 7,5 kg7, comma, 5, start text, space, k, g

Kaylis [27]

Answer: $3\ kilograms$

Step-by-step explanation:

It is important to remember that, by definition, proportional relationships have the following form:

$y=kx$

Where "k" is the constant of proportionality.

We know that Maddy assume that the relation between the volume and the weight is proportional.

Then, let be "V" the volume in liters and "w" the weight in kilograms.

We can write the following equation:

$V=kw$

So, if the boat of 555 liters weights 7.5 kilograms, we can find "k":

$555 =k(7)\\\\k=\frac{555}{7}\\\\k=74$

In order to solve the exercise, substitute the value of "k" and $V=222$ into the equation and solve for "w". Then:

$222=(74)w\\\\\frac{222}{74}=w\\\\w=3$
