If you are going to use mental math, round $0.98 up to $1.
Rounded, the cost of the 30 songs is $30.
However, since you rounded at the beginning, you need to subtract 2 cents for every song you purchased from the total of $30.
Multiply 30 by $0.02 to get $0.60. Subtract $0.60 from $30.
Your answer should be $29.40.
The answer would be C! Correct me if I’m wrong guys
Answer:
Let's use the formula for the volume of a rectangular prism;
V = l · w · h
Where 'l' represents the length, 'w' stands for the width, and 'h' displays as the height. (V evidently stands for the volume)
<u>What we know:</u>
- Volume = 240 ft
- Length = 4 ft
<u>What we need to find out:</u>
Let's plug in what we know into the formula:
V = l · w · h
<u>240</u> = <u>4</u> · <u>4</u> · h
Now let's solve for h:-
240 = 16 · h
240 = 16h
Get rid of h's co-efficient by dividing 16 from both sides because the inverse operation of multiplication(since 16 is being multiplied by h) is division.
÷16 ÷16
Finally, you would end up with a result of:
<u>15</u> = h
Hence, the height of this prism is <u>15 feet</u>.
Answer:
30 students in the class.
Step-by-step explanation:
There are several which in which we can approach this question:
We can do this question using direct proportion.
"If 18 girls represent 60%, how many students represent 100%?"
