Step-by-step explanation:
To find the answer you have to put it into y=mx+b format.
This means that it will be 5y=-30x+15
So it will simplify to y=-6x+3
This means that:
If y=2
You substitute then…
2=-6x+3
So x would equal 1/6.
The answer is eighty because you have to divide five into 133
Not so sure about the second one, but the first one is pretty simple:
The area of a circle = pi x radius^2
Since you need to find the area of the entire dvd, I'm assuming they mean if the hole in the center wasn't there, so add that to the diameter.
12+1.5 = 13.5
Half of the diameter is the radius, so half of 13.5 = 6.75
Now, multiply pi (3.14) by the radius, but have the radius squared. You'd write the equation like this:
3.14 x 6.75^2 (or on paper, the ^2 would be a small two diagonal from the 5)
Actual answer: 143.06625
You can round that to 143.

Hi! Hope this helps!
Step-by-step explanation:
A verb is used to describe actions.
Example: I JUMPED over the rock. In this sentence the verb is JUMPED
Use the conditional probability formula, P(a|b) = P(a and b)/P(b)
