Answer:

Option B

Step-by-step explanation:

In order to find the answer to this question you need to use the slope formula and solve by subtracting the numerator and the denominator.

$slope=\frac{y^2-y1}{x^2-x^1}$

$x^1,x^2=(2,5)$

$y^2,y^1=(8,7)$

Substitute:

$\frac{8-7}{2-5}$

Subtract:

$8-7=1$

$2-5=-3$

$=\frac{-1}{3}$

Hope this helps.

A hollow toy, with the dimensions shown in the figure, is to be stuffed with rigid foam. What is the maximum amount of foam that

Fudgin [204]

Option B: 67.02 cubic inches

<h2>Given that:</h2>

The diagram consists of two parts:

First a cone on the top with 12 inches height and 4 inches diameter.

Second a semi sphere with diameter of 4 inches.

<h2>Calculations:</h2>

The amount of foams that can be stuffed with foam is total volume of both the containers.

Volume of the given cone of 12 inches height and 4 inches diameter can be given as:

$\dfrac{1}{3} \times \pi \times 2^2 \times 12\\= 50.265 \: \rm inch ^3$

Volume of the semi sphere of 4 inches diameter can be given as:

$\dfrac{2}{3} \pi \times 2^3\\= 16.755 \: \rm inch^3$

Thus total volume is 50.265 + 16.755 = 67.02 cubic inches.

Thus option B : 67.02 cubic inches is the needed volume.

A box contains balls numbered 3 through 15.

Phantasy [73]

Answer: 6/13

Step-by-step explanation:

A box contains balls numbered 3 through 15. This means that the sample space = {3 , 4 ,5 , 6 ,7, 8, 9, 10, 11, 12, 13, 14, 15,}

The total number of sample space = 13

Therefore : the probability of picking 3, 5, 9, 11, 12, 15 , will be the total number of times they appear in the sample space divided by the number of sample space.

number of times 3 appears = 1

number of times 5 appear = 1

number of times 9 appear = 1

number of times 11 appear = 1

number of times 12 appear = 1

number of times 15 appear = 1

All together , they appeared 6 times

Therefore : the probability of picking one of the numbers = 6/13
