Answer: first option
Step-by-step explanation:
The volume of a regular pyramid can be calculated with the following fromula:
Where B is the area of the base of the pyramid and h iis the height of the pyramid.
The base is a square, therefore, its area B is:
You know that the height is 3, therefore, you can substitute these values into the formula.
THerefore, the volume of the pyramid is:
So if 1/2 = 18 miles, we want to first find how many sets of 1/2 are in 21/2. We can just do this by dividing.
(21/2) / (1/2) = 21
So we know that there are 21 sets of 1/2 in 21/2, and since 1/2 and 18 are equal, we can say we know there are 21 sets of 18.
We can multiply to find this.
21 * 18 = 378
So two towns are 378 miles apart.
Answer:
x = 115 - p
Step-by-step explanation:
generally in algebra you will use the letter "x" to represent a value you do not know, so it wants an algebraic expression for "p subtracted from 115", this can be rewritten as 115 - p. So the unknown value "x" is equal to 115 - p.
6 divided by 10 would be 60 percent and .60 as a decimal
The answer is 8.4 so you would need 9 rolls of ribbon
