Answer: The number of cubic yards of concrete that are needed is 720.

Step-by-step explanation: The same formula for this type of shape stays the same: l*w*(h or d).

240 * 4 = 960

960 * 0.75 = 720

How do I solve this systems of three equations problem?
Serhud [2]

Answer:

You have to eliminate one of the variables when the equations are added.

A) x + 2y + z = 10

B) 2x -y +3z = -5

C) 2x -3y -5z = 27

We mulutiply A) by 2 then add it to B and C

A) 2x + 4y + 2z = 20 and the sum =

6x = 42  Luckily, the "y" and "z" variables cancel out and we find:

x = 7  

Then we use x =7 in calcucating equation A) and B)

A) 2y + z = 3

B) -y + 3z = -19

THEN solve for y and z by eliminating variables.

College student makes decorative Styrofoam Lions and Husky's which she sells each year. Each one uses 8 oz of Styrofoam and take
Travka [436]

Answer:

She should make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is  $1109

Step-by-step explanation:

The given information are;

The volume required to make each lion = 8 oz

The time it takes to make each lion = 35 minutes

The amount of profit each lion brings = $2.50

The volume required to make each Husky = 12 oz

The time it takes to make each Husky = 20 minutes

The amount of profit each Husky brings = $3

Let the number of lion Styrofoam cups she makes = x

Let the number of Husky Styrofoam cups she makes = y

Therefore, we have;

x × 35 + y × 20 = 9650..........(1)

x × 8 + y × 12  = 3840.............(2)

Dividing equation (2) by 8 and making x the subject, we get;

x × 8/8 + y × 12/8  = 3840/8

x + 4/3·y = 480

x = 480 - 4/3·y

Substituting the value of x in equation (1) gives;

(480 - 4/3·y) × 35 + y × 20 = 9650

16800 - 80/3·y = 9650

y = 268.125

x = 480 - 4/3·y  = 480 - 4/3×268.125 = 122.5

Therefore, she can make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is therefore given by the following equation;

The maximum profit = 122 × 2.5 + 268 × 3 = $1109.
