A regular-size box of dog treats measures 3 1/4 inches by 7 1/2 inches by 12 inches. The manufacturer also sells a small-size box that has a volume that is 3/10 of the volume of the regular-size box.
What is the volume of the small-size box of dog treats?
Enter your answer as a mixed number in simplest form by filling in the boxes.
Answers
Answer:
87 3/4
Step-by-step explanation:
If the manufacturer also sells a small-size box that has a volume that is 3/10 of the volume of the regular-size box, then the volume of the small-size box of dog treats would be 87 3/4.
How to determine the volume of the boxTo determine the volume of the box, we would first convert the measurements of the regular-size boxes to a proper fraction. We could proceed as follows:
3 1/4 inches = 13/4
7 1/2 inches = 15/2
12 inches
Now we sum the volumes as follows: (13/4) * (15/2) * (12/1)
= 585/2 cubic inches
Now, we would find 3/10 of 585/2 cubic inches
= 87.75 inches or 87 3/4 cubic inches.

Johnny runs a hot dog stand. On Wednesday morning, he had 32 dozen hot dogs at his stand. The graph shows the number of hot dogs (in dozens) that remained unsold at the end of each day of sales.
Answers
I saw you got it in the comment section of the post, but yes, he sold 30 dozen hot dogs on Wednesday.
By using the information of the graph, we conclude that he sold 2 dozen (24 hot dogs) on Wednesday.
How many hot dogs did Johnny sell on Wednesday?
The graph shows how many dozens of hot dogs Johnny had at the end of each day.
We know that he started with 32 dozens, and in the graph, we can see that at the end of Wednesday he had a total of 30 dozens.
Then the amount that he sold that day is:
32 dozens - 30 dozens = 2 dozens.
On Wednesday, he sells 2 dozen of hot dogs.

|z-7|-|z-9| if Z is less than 7
Answers
Answer:
If z<7, then z-7 is negative, and |z-7| is positive. So, with the understanding that z-7 is positive, the first part of this expression becomes:
7-z for z<7
Similarly: if z<7, then z-9 is negative and |z-9| is positive. Thus, -|z-9| is equivalent to (9-z).
|z−7|−|z−9|, if z<7 becomes (7-z) - (9-z) for z<7. Simplifying this, we get:
7 - z - 9 + z = -2
Answer:
7 - z - 9 + z = -2
A storage box has a base area of 314.5 square inches and a height of 8.5 inches.
What is the volume of 5 of these boxes?
Enter your answer as a decimal in the box.
Answers
Answer:
13366.25in cubed
Step-by-step explanation:
To find the volume of a rectangular prism, you need the formula:
V = (L × H) × W
Luckily, L × H is the base of the shape. So we can change it into:
V = B × W
Step 1
Plug in the values! That’s what we do everytime!
V = 314.5 × 8.5
Step 2
Multiply 314.5 by 8.5.
V = 2673.25
BUT ITS NOT THE ANSWER YET!Step 3
Because you need to find the volume of 5 of the boxes, multiply 2673.25 by 5.
2673.25 × 5 = 13366.25
Thus, the volume of 5 of the boxes is 13366.25in cubed.

Answers
1) Correct option is C)
A fair coin is tossed 100 times and the head occurs 58 times and tail 42 times.
The experimental probability of getting a head is :
P(E)=
Total outcomes divided by Number of head
58/100 = 29/50 (29/50x100) = 58% (C)
2) 19%
Answer:
1. 42%
2. 33%
Step-by-step explanation:
1. Relative frequency = Number of successful trials ÷ Total number of trials
plug the numbers in and we get 42/100. 42/100 = 0.42 = 42%
2. Experimental probability = Number of in which the outcome occurs ÷ Total number of trials
plug the numbers in and we get 2/6 = 1/3 = 33%
14. MULTIPLE CHOICE The number of students in the marching band increased from 100 to 125. What is the percent of increase? (Skills Review Handbook) (A) 20% (B) 25% (C) 80%
(D) 500%
Answers
The percentage of the increase will be 25% when the number of students in the marching band increased from 100 to 125.
What is the percentage?The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.
It is given in the question that the number of students in the marching band increased from 100 to 125 so we need to find the percentage increase of the students.
The percentage increase of the students will be calculated as:-
% increase=[(125-100)÷(100)]x100
% increase=[(25)÷(100)]x100
% increase= [0.25x100]
% increase= 25%
Hence the percentage of the increase will be 25% when the number of students in the marching band increased from 100 to 125.
