If the volume for 3-d pyramid a is 300 cm3 and the volume for 3-d pyramid b is 900 cm3, how many times bigger is the volume of pyramid b than pyramid a?

Volume of pyramid B is three times bigger than the volume of pyramid A

Step-by-step explanation:

We are given that:

The volume for 3-D pyramid A is 300 cm³ .

and the volume for 3-D pyramid B is 900 cm³.

We have to tell how many times bigger is volume of pyramid B than volume of pyramid A.

volume of 3-D pyramid B= 900 cm³

                                        = 3×300 cm³

                                       = 3×volume of 3-D pyramid A

Hence, Volume of pyramid B is three times bigger than the volume of pyramid A

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
