➷ 45 minutes is 3/4 of the total time

A simple way to do this is to find 1/4 of the time

To do this, divide by 3:

45/3 = 15

15 minutes is 1/4 of the time

To find the whole time, multiply this value by 4:

15 x 4 = 60

Subtract the time already passed from this:

60 - 45 = 15

It will take her 15 more minutes to finish building her wall.

➶ Good Luck (:

Assume a 14-inch pizza can be purchased as a whole pizza, a half pie, or one of 8 slices. Determine
marshall27 [118]

Answer:

The diameter of the pizza = 14 in

Radius of the pizza = (14/2)in = 7in

Area of a whole pizza =

πr^2

=( 22/7 × 7^2)in^2

=( 22/7 × 49)in^2

154 in^2

Area of a half pie =( 1/2 × 154)in^2 = 77in^2

Area of one of 8 slices = (1/8 × 154)in^2 = 19.25in^2

Hope it helps

2. Riverside Elementary School is holding a school-wide election to choose a school color. Five-eighths of the votes were for bl
SVEN [57.7K]

Answer:

<em>a. 180 votes were for blue</em>

<em>b. 60 votes were for green </em>

Step-by-step explanation:

<u>Fractions</u>

It's known 5/8 of the votes of a school-wide election were for painting the school blue. Suppose there were x voters in school.

Since 5/8 were for blue, then

1-\frac{5}{8}=\frac{3}{8}

Were for the rest of the colors. It's also known 5/9 of the remaining votes were for green, thus

1-\frac{5}{9}=\frac{4}{9}

of the remaining votes were for red.

The votes for red are:

\frac{3}{8}\cdot\frac{4}{9}=\frac{1}{6}

of the total voters.

We know these were 48 votes, thus

\displaystyle x=\frac{48}{\frac{1}{6}}

x = 288

There were 288 voters in school.

a. 5/8 were for blue, that is:

\frac{5}{8}*288=180

180 votes were for blue

b. 288-180 = 108 votes were for others than blue, and 5/9 of them were for green:

\frac{5}{9}*108=60

60 votes were for green and 108-60=48 votes were for red (as expected)
