Answer:

\frac{2}{3}

Step-by-step explanation:

Sum the frequency column to find the total number of students

total = 2 + 9 + 5 + 5 + 3 = 24

number of students finished in less than 20 mins = 2 + 9 + 5 = 16

fraction of students = \frac{16}{24} = \frac{2}{3}

it takes an air pump 5 minutes to fill a twin sized air mattress (39 by 8.75 by 75 inches). how long will it take to fill a quee
Shalnov [3]

It take 8.205 minutes to fill a queen sized mattress.

<h3>What is volume?</h3>

'Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

Given dimensions:

Twin sized air mattress (39 by 8.75 by 75 inches).

Queen sized mattress (60 by 8.75 by 80 inches)

Now, Volume of twin sized mattress

=39* 8.75* 75

= 25593.35 cubic inch

Volume of queen sized mattress,

=60* 8.75* 80

= 42000 cubic inch

as, To fill 25593.35 cubic inch it takes 5  minutes

so, to fill 1 cubic inch = 5/25593.35

and, So to fill 42000 cubic inch it will take = 42000* 5/25593.35

=8.205 minutes

You are sitting on the ground flying a kite.
Neko [114]

Answer:

Height of the kite = 36 feet

Step-by-step explanation:

Triangle attached in the figure shows the complete picture,

I am sitting at point A, string connecting the kite and me is side AC, height of the kite from the ground is side BC and side AB representing the distance between me and the kite.

Length of side BC = h

Length of side AC = 39 feet

Length of side AB = 15 feet

By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

(39)² = (15)² + h²

h² = 1521 - 225

h² = 1296

h = √1296

h = 36 feet

Therefore, kite is at 36 feet height.
