It would be: ∅/360 * πr²

here, ∅ = 120

= 120/360 * 3.14*(3)²

=9.42 m²

What is the surface area of the right prism?

madreJ [45]

Answer:

The surface area of right prism is 12 feet² , option D

Step-by-step explanation:

Given as :

The measure of base = 4 ft

The height of base = 0.5 ft

The surface area of right prism = perimeter of base × height + 2 × base

Now ,

Perimeter of base = 4 + 4 = 8 ft

So, The surface area of right prism = 8 × 0.5 + 2 × 4

Or, The surface area of right prism = 4 + 8

∴ , The surface area of right prism = 12 feet²

Hence The surface area of right prism is 12 feet² . Answer

What is the solution to the equation k + 4 3/4 = 7?

Artemon [7]

Hi I don’t know if this is right but I got that k is equal to 4 I got that because if you do

4 times 3/4 you get 12/4 that is equal to 3.
Now you have k + 3=7 you move 3 to the other side and make it negative
K= 7-3
K=4

Hope this helped!

Jack’s shipping company has to transport boxes of industrial nuts and industrial bolts to its clients. Each box of industrial nu

Ipatiy [6.2K]

Answer:

The correct option is B.

Step-by-step explanation:

Let the boxes of nuts be x and the boxes of bolts by y.

The weight of nut box is 100 kg and the weight of bolt box is 200 kg.The maximum weight the company’s cargo container can hold is 24,000 kilograms.

$100x+200y\leq 24000$

$x+2y\leq 240$ .... (1)

The company needs to transport a minimum of 160 boxes per cargo container.

$x+y\geq 160$ .... (2)

Plot the above inequalities on the coordinate plane.

The related equations are

$x+2y=240$ .... (3)

$x+y=160$ .... (4)

The x-intercept of equation 3 is (240,0) and the y-intercept is (0,120).

The x-intercept of equation 4 is (160,0) and the y-intercept is (0,160).

Check the inequality by (0,0).

$0+2(0)\leq 240$

$0\leq 240$

This statement is true, therefore the shaded region of inequality (1) contains (0,0).

$x+y\geq 160$

$0+0\geq 160$ \

$0\geq 160$

This statement is false, therefore the shaded region of inequality (2) does not contains (0,0).

Therefore graph (2) represents the solution and option B is correct.
