Joe has two empty boxes, one box is 15 inches wide, 20 inches long and 10 inches high. The second box has the same length and width but is 4 inches taller. How much additional spaces is in the box

Space in the box = volume
volume = length x width x height
box 1 volume = 15 x 20 x 10 = 3000
box 2 volume = 15 x 20 x 14 = 4200
how much space is left = box 2 - box 1 = 1200 inches

There are 10 boys and 13 girls in Ms. Kelso’s homeroom. She is going to select one boy and one girl to act as homeroom representatives for student council. How many different pairs of students could Ms. Kelso choose? A.) 10 B.) 23 C.) 130 D.) 230

The notation for this is {10 \choose 1} \cdot {13 \choose 1}.

Where you should know that {n \choose k} =  \frac{n!}{k!(n-k)!}

When choosing only one boy and one girl, it becomes simple-ish:

\frac{10!}{9!} \cdot \frac{13!}{12!} = 10 \cdot 13 = 130

So I would vote for C, hoping I didn't overlook anything...

A teacher gave his students the four graphs below. Which graph represents a geometric sequence?

The arithmetic sequences always graph as points along a line.

In a geometric sequence, each term is equal to the previous term, multiplied (or divided) by a constant.

The  exponential functions have a very special property:

equal changes in the input cause the output to be successively multiplied by a constant.

Geometric sequences also have this same special property:geometric sequences always graph as points along the graph of an exponential function.

The sequence 6.25,12.5,25,50,100 is a geometric sequence  so its graph will represent a geometric sequence.

A student spent 3/4 of an hour reading an article and 2 1/6 hours writing an essay about what he read. how much time did the student spend on the assignment?

So, we need to add 3/4 + 2 1/6.

First, let's find a common denominator.

12 is one.

4 x 3 = 12  3 x 3 = 9        6 x 2 = 12   1 x 2 = 2     2/12 & 9/12 = 11/12

2 + 0 = 2.  2 + 11/12 = 2 11/12.

2 11/12 is your answer.

If you have any questions, comment below.

Glad I could help, and good luck!

Joel is laying pipe for a sprinkler system before he plants his lawn. The lawn is a rectangle, 15 feet long and 8 feet wide. He needs to lay a piece of pipe that will run along the diagonal of the lawn. It will divide the area of the lawn into two right triangles. What will be the length of the pipe? A. 120 feet B. 17 feet C. 23 feet D. 289 feet

Answer: B is the right answer. Diameter of the given rectangular lawn=17 feet.


Step-by-step explanation:

Given: A rectangular lawn 15 feet long and 8 feet wide.

To find the diagonal of lawn such that it will divide the area of the lawn into two right triangles. [i.e. diagonal will be the hypotenuse]

So by Pythagoras theorem of right triangles,

hypotenuse^2=perpendicular^2+base^2\\\Rightarrow\ diagonal^2=length^2+width^2\\\text{substitute the values of length and width,we get}\\\Rightarrow\ diagonal^2=15^2+8^2=225+64=289\\\Rightarrow\ diagonal=\sqrt{289}= \sqrt{17\times17}=17

Therefore diameter of the given rectangular lawn=17 feet.

Find the volume of the toy bus pictured below whose sides are 4.5 cm, 6.8 cm, and 8.2 cm (to the nearest hundredth)?

Answer:

V=250.92 cm ^3

Step-by-step explanation:

Given:  A toy bus  whose sides are 4.5 cm, 6.8 cm, and 8.2 cm.

To find: The volume of the toy bus.

solution: It is given that a toy bus has sides 4.5 cm, 6.8 cm, and 8.2 cm, then the volume of the toy bus is given as:

V=l{\times}b{\times}h

Substituting the given values in the above formula, we get

V=4.5{\times}6.8{\times}8.2

V=30.6{\times}8.2

V=250.92 cm ^3

Therefore, the volume of the toy bus is 250.92 cm ^3.

A pitcher of water is three-fourths full. Four cups of water are served from the pitcher. Then the pitcher is two-thirds full. How many cups of water can the pitcher hold?

So hmmm let's say, the pitcher has "x" cups when full
so, it was (3/4)x then 4 cups came out, went down to (2/3)x

now, if we subtract (2/3)x from (3/4)x, their difference will be the 4cups that were served

thus   \bf \cfrac{3}{4}x-\cfrac{2}{3}x=4\implies \cfrac{3x}{4}-\cfrac{2x}{3}=4\implies \cfrac{3\cdot 3x-4\cdot 2x}{12}=4&#10;\\\\\\&#10;\cfrac{9x-8x}{12}=4\implies \cfrac{x}{12}=4

and surely, you'd already know what "x" is

An 18 oz jar of peanut butter cost $2.19. A 48 oz jar of peanut butter sells for $4.39. Which size jar is the better buy? Why? Will give 15 points.

Ok, so we need to find the price per ounce.  If we take 2.19 and divide it by 18 that gives us 0.12 per ounce of peanut butter.  If we take 4.39 and divide it by 48 that gives us 0.09.  So we know the cheapest option is the 48 ounce jar.  Also, teachers love it if you include something like "However, if you don't need 48 ounces of peanut butter, the other jar is only 0.03 more per ounce."
