Answer:
2 is growth factor
Step-by-step explanation:
We are given expression
We can use formula
here ,
a is initial value
b is growth factor
so, we get
so, growth factor is 2
So, Number of leaves doubled after one week
So, 2 is growth factor
Multiply by 10
2x+50=190-5x
190=2x+50+5x
140=7x
x=20
Answer:
C - 13
Step-by-step explanation:
Answer:
He made approximately 32 free throws.
Step-by-step explanation:
Assuming that there's a typo in the question and that he made 57% of his attempted free throws, then we can solve it as shown below:
We can apply a rule of three in order to calculate the number of free throws he made. This is done as follows:
56 free throws -> 100%
x free throws -> 57%
56/x = 100/57
100*x = 57*56
x = 57*56/100 = 31.92
It can also be solved by transforming the percentage in a fraction such as 57% = 57/100 and then multiplying it by the total attempts.
free throws made = 56*57/100 = 31.92
He made approximately 32 free throws.
