Answer:
63.6 m^2
Step-by-step explanation:
A = (pi)r^2
r = d/2 = 9 m / 2 = 4.5 m
A = (3.142)(4.5 m)^2
A = 63.6 m^2
Answer: $16.40
Step-by-step explanation:
Answer:
1/4
Step-by-step explanation:
there is 3 black marbles and 3+4+5=12 total marbles. 3/12=1/4
First you need to set up the frequency chart. The columns can be Multiples of 3 and not multiples of 3. The rows can be Multiples of 4 and not multiples of 4 like shown in step 1. in attached file
Then we start adding in values I will add 20 as the total numbers as in step 2 in attached file.
Next I place in the Multiple of 9 that is not 3, and the total multiples of 3, and total multiples of 4 in step 3.
Based on the totals I can assume that there are 10 that are not multiples of 4 and ten that are not multiples of 3 shown in step 4
In step 5 I fill in the insides so that the totals will add up so we know that for multiples of 3 9+1=10 so I fill in the one at the top left corner.
In step 6 the only numbers left to fill in the totals would be 9 and 1 for values that are not multiples of 3 and not multiples of both.
The work is shown in the attached images. Each equation is labeled for slope intercept and standard form
y=-1/5x +18/5
5y+x=18
