Answer:

108 inches square.

Step-by-step explanation:

Here

base= b= 4 inches

height = h=w=  3.5 inches

and length = l= 9  inches

The surface area is the total area of all the sides of the prism. So the area of the 2 triangles is given by

Area of the 2 Δs= b* h= 4*3.5=  13.5 inches square

Area of the 3 rectangles = l*w(3)= 3( 9*3.5)= 94.5  inches square.

Total area = 13.5 + 94.5 = 108 inches square

This can be found by applying another formula.

Surface area of the triangular prism = bh + ( s1+s2+s3) H

                                                         = 4*3.5 + (9+9+9)3.5

                                                          = 13.5 + 94.5= 108 inches square.

where H is the width of the recatngles which is equal to the height of the triangles.

Lucy earns money babysitting. Her earnings and hours worked represent a direct variation. She worked for 4 hours and earned $25.
SashulF [63]

For this case we have that by definition, a direct variation is given in the form:

y = kx

Where:

k: It is the constant of proportionality

According to the statement we have to:

y = 25\\x = 4

Substituting:

25 = k4\\k = \frac {25} {4}k = 6.25\ for\ \frac {dollars} {hour}

On the other hand we have:

y = 4\\x = 25\\4 = k25\\k = \frac {4} {25}

k = 0.16\ for\ \frac {hours} {dollar}

Answer:

k = 6.25 for \frac {dollars} {hour}\\k = 0.16 for \frac {hours} {dollar}

Mei has 8 jars of soup. Each jar contains 300 milliliters of soup. What is the smallest pot Mei can use to heat all the soup?
balu736 [363]
<h3>Mei can use the smallest pot with capacity of 2400 milliliters to heat all the soup</h3><h3><u> Solution:</u></h3>

Given that,

Mei has 8 jars of soup

Each jar contains 300 milliliters of soup

Therefore,

Total amount of soup = 300 ml x 8 jars

Total amount of soup = 300 \times 8

Total amount of soup = 2400 ml

Hence, Mei can use the smallest pot with capacity of 2400 milliliters to heat all the soup

The greatest number of adult tickets sold if the box office receipts was not more than $3,190 is 328.

<h3>How to find the greatest number of adult tickets sold ?</h3>

let

number of children tickets = x

number of adult ticket sold = 1 / 3 x

The greatest number of adult tickets sold if the box office receipts was not more than $3,190 can be calculated as follows:

The equations that represent the situation is as follows:

5.50x + 8.50 (1/3 x) = 3190

5.50x + 2.83333333333x = 3190

8.33333333333x = 3190

x = 3190 / 8.33333333333

x = 982.839313573

x ≈ 983

Therefore,

adult ticket = 983/3 = 328

Therefore, the greatest number of adult tickets sold if the box office receipts was not more than $3,190 is 328.
