Answer:

28 non-blue marbles.

Step-by-step explanation:

Initial probability of choosing a blue marble = 4/12

Let the number of non-blue marbles to be added be x.

\frac{4}{12+x} =\frac{1}{10}

A small theater can seat 600 people. The number of rows in 10 less than the number of seats in each row. How many seats are in e
Kisachek [45]

Answer:

30 seats

Step-by-step explanation:

To answer this question, we will be assigning values for both rows and seats.

R = Rows

S = Seats

Remember that rs = 600

r = s - 10, plug this equation into rs = 600, and factor it:

s(s-10) = 600

s^2-10s-600 = 0

(x-30)(x+20) = 0

There are 30 seats in the row. To determine which one is your answer, your answer MUST be positive because it is impossible to have negative seats. (x-30) is 30, which is the positive value found when factoring.

Alexxandr [17]

The maximum amount of supplies that the storage unit can hold is 28 ft³

<h3>How to calculate the volume of a rectangular prism?</h3>

For us to calculate the volume or amount of space in Evan's prism, we will first of all calculate the volume of rectangular prisms. Formula is;

V = Length × width × height.

We are given;

length = 4 feet

width =  3.5 feet

height of the prism = 2 feet.

Thus;

V = 4 * 3.5 * 2

V = 28 ft³

Thus, the maximum amount of supplies that the storage unit can hold is 28 ft³
