What is the volume of the prism
almond37 [142]

The volume of a rectangular prism or cube is: Length × Width × Height

In this case,

- the length of the prism is 2 feet

- the width of the prism is 1.5 feet

- the height of the prism is 1.5 feet

Multiply the above to find the volume: 2 × 1.5 × 1.5 = 4.5 ft³

Keep in mind that volume is represented in cubic units!

Tickets to the zoo cost $12 for adults and $8 for children. The school
larisa [96]

Answer:

Step-by-step explanation:

Given

240 = 12x + 8y

Required

Plot a graph

First, we need to determine the minimum and maximum values of x and y

For x:

Minimum = 0

For maximum; Let y = 0

240 = 12x + 8y

240 = 12x + 8 * 0

240 = 12x

Solve for x

x = 240/12

x = 20

For y:

Minimum = 0

For maximum; Let x = 0

240 = 12x + 8y

240 = 12 * 0 + 8 * y

240 = 8y

Solve for y

x = 240/8

x = 30

What is the length of side BC of the triangle? Enter your answer in the box. units Triangle A B C with horizontal side B C. Vert
harina [27]

Answer:

The length of BC = 28 units

Step-by-step explanation:

* In triangle ABC

∵ Angles B and C are congruent

∴ m∠B = m∠C

* In any triangle if two angles are equal in measure, then the triangle is isosceles means the two sides which opposite to the congruent angles are equal in length

∴ AB = AC

∵ AB = 4x - 7

∵ AC = 2x + 7

∴ 4x - 7 = 2x + 7 ⇒ collect like terms

∴ 4x - 2x = 7 + 7

∴ 2x = 14 ⇒ divide both sides by 2

∴ x = 14 ÷ 2 = 7

* Now we can find the length of BC

∵ The length of BC = 4x ⇒ substitute the value of x

∴ The length of BC = 4 × 7 = 28 units
