Answer:
C
Step-by-step explanation:
We are given
The student council earned $1.25 for every cup of hot chocolate it sold
and $0.75 for every cup of apple cider it sold
total number of cup is 375
We can see that first term is 1.25x
and we have
The student council earned $1.25 for every cup of hot chocolate
so, to find total cost of hot chocolate , we multiplied 1.25 with x
that's why
x must be the number of cups of hot chocolate sold
So the answer must be C
Answer:
4.67 hours
Step-by-step explanation:
The computation is shown below:
Given that
There is 14 hours remaining for devoting in a project
Also it must be completed in 3 days
So the number of hours she need to devote each day is
= 14 hours ÷ 3 days
= 4.67 hours
Answer:
x=6
Step-by-step explanation:
7+5 (x-3)=22
Subtract 7 from each side
7-7+5 (x-3)=22-7
5(x-3) = 15
Divide each side by 5
5(x-3)/5 = 15/5
x-3 = 3
Add 3 to each side
x-3+3=3+3
x=6
Given:
The shape is square.
To find:
The surface area and volume of a square.
Explanation:
The length of each side of the square is "a" units.
The formula for the surface area of the square is,

The formula for the volume of the square is,

Using these formulas, we can find the surface area and the volume of the square that has side length "a" units.
For example:
Let the side length of 3cm for a square.
So, the dimensions are 3cm by 3cm by 3cm.
That is,
The Length is 3cm.
The breadth is 3cm.
The height is 3cm.
So,

The surface area of the square is,

Therefore, the surface area of the square is 54 square cm.
The volume of the square is,

Therefore, the volume of the square is 27 cubic cm.
