Answer:
A) h=0.5x+7
Step-by-step explanation:
given
initial height = 7 feet
growth rate = 6 in = 0.5 feet / year
let # of growing years = x
For a linear growth rate:
height after x years, h = initial height + (# of growing years) * (growth rate)
substiuting the values above into this equation
h = 7 feet + (x years) * (0.5 feet/year)
or
h = 7 + 0.5x (rearranging)
h = 0.5x + 7
Do you go to k12 7th grade? if so i do to!! also sorry i dont know the answer :(
1st card = 13/52
2nd card = 12/51
3rd card = 11/50
4th card = 10/49
5th card = 9/48
13/52 * 12/51 * 11/50 * 10/49 * 9/48 = 33/66640
there are 4 different suits so 4 * 33/66640 = 33/16660
answer is C
3x-15=51
3x=36
X= 12
Thus the number is 12
Water in the swimming pool initially = 2.5 million liters
Water in the swimming pool after evaporation = 2 million liters
Therefore, volume of water evaporated = 2.5 million liters - 2 million liters
=0.5 million liters
To find the percent of water evaporated, divide the volume of water evaporated by the volume of water in the swimming pool initially and then multiply it by 100.
Percent of water evaporated =( 0.5 / 2.5) x 100 =20%
