Step-by-step explanation:

9x+6+5x+90°= 180°

14x+96=180

14x=180-96

14x=84

x= 84/14

x=6

so, <A=5x=5(6)=30°

<B=9x+6=9(6)+6=54+6=60°

<C = 180-(30+60)=180-90=90°

The base of a rectangular prism has an area of 13 2/3, and the height of the prism is 8 5/6. What is the volume of the prism? Be

Fed [463]

Answer:

120 $\frac{13}{18}$

Step-by-step explanation:

The formula for finding the volume of a prism is:

V = Bh

You have to convert 13 $\frac{2}{3}$ into an improper fraction, like so:

$\frac{41}{3}$

Convert the other:

$\frac{53}{6}$

Multiply:

$\frac{41}{3}$ · $\frac{53}{6}$ = $\frac{2173}{18}$

Convert to mixed fraction:

Amanda [17]

Answer:

$40\ bottle\ caps$

Step-by-step explanation:

we know that

The scale is $\frac{2.4}{1}\ \frac{cm}{ft}$

That means

2.4 cm in the model represent 1 foot in the real

In this problem

The restaurant is 20 feet tall

Find the height of the model

Multiply the actual height of the restaurant by the scale 2.4

$20\ ft=20(2.4)=48\ cm$

A bottle cap is 1.2 cm tall

To find out the number of bottle caps divide the height of the model by 1.2

$\frac{48}{1.2}= 40\ bottle\ caps$
