Aha please help me... Find the height of a right square pyramid that has a rectangular
base area of 70 square units and a volume of 140 cubic units.
OA) 2 units
OB) 6 units
OC) 1 units
OD 18 units

Height = 6 units

Step-by-step explanation:

Recall that the volume of a pyramid is defined as:

Volume = 1/3  Base x Height

Then, in our case we have:

140 = 1/3 (70) x Height

we multiply by 3 both sides to eliminate the fraction on the right:

420 = 70  Height

divide by 70 to isolate the Height completely:

420 / 70 = Height

Therefore, the height is:

Height = 6 units

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

a. is correct
