Answer:

320

Step-by-step explanation:

Well, the volume of a pyramid is 1/3 b * h

What is the height of one of these pyramids? Well, they tell you that it's 10. What is the base? It's 6 * 8 = 48

10 * 48 * 1/3 = 160

Now multiply by 2 because there are two pyramids. One on top and one one bottom. 160 * 2 = 320

What is the square root of 100 times two divided by two
gogolik [260]

Answer:

10 is your answer

Step-by-step explanation:

√((100 * 2)/2)

Simplify. First, follow the Parenthesis. Combine 100 with 2

100 * 2 = 200

Next, divide by 2

200/2 = 100

Root 100

√100 = √10 * √10 = 10

10 is your answer

~

An easier way to solving this is to first cancel out the 2's ( multiplying 2 and dividing 2 would do nothing), and just square rooting 100, giving you the answer 10.

ALGEBRA HELP!! Write an exponential function represented by the table.
marysya [2.9K]

Answer:

y=-50*0.2^x

Step-by-step explanation:

the formula for an exponential function is:

y=a*b^x

what do we multiply -50 by to get -10?

-50x=-10

x=-10/-50

x=1/5

x=2/10

x=0.2

This initial value here is -50, it is the first in the table

y=-50*0.2^x
