Answer:
6/7
Step-by-step explanation:
because there are 28 properties in all
4 of them are railroads
but we're not looking for the probability of selecting a railroad, which would be 4/28 or 1/7, but for not selecting a railroad
and 24 of them are not railroads
So the probability of not selecting a railroad is 24/28, which simplified/reduced is 6/7
a) So we know the formula of finding the circumference: 2*pi*R.
Assuming we make pi = 3.14: 2 * 3.14 * 7 = 43.96.
b) We also know the formula of finding the area: pi * r^2.
3.14 * 7^2. Using PEMDAS:
3.14 * 49 = 153.86
Answer:
6:5
Step-by-step explanation:
because 30 and 36 can both be divided by 6;
36/6= 6
30/6= 5
so the ratio is 6 to 5
Answer:
Huh?
Step-by-step explanation:
Answer:
x =-2.1
Step-by-step explanation:
X/2+10=8.95
Subtract 10 from each side
X/2+10-10=8.95 -10
x/2 =-1.05
Multiply each side by 2
x/2*2 =-1.05*2
x =-2.1
