Answer:
1.30 hours
Step-by-step explanation:
Put the given number in the formula and do the arithmetic. The value of "d" is given as 7, so you are evaluating the expression ...
duration = 0.07×7^(3/2) . . . . put 7 where "d" is in the expression
= 0.07×18.520 . . . . . . . . . . . . evaluate 7^(3/2)
= 1.2964 . . . . . . . . . . . . . . . . . do the multiplication
≈ 1.30 . . . . rounded to hundredth
The duration of a storm 7 miles in diameter is predicted to be 1.30 hours.

Step-by-step explanation:
This problem is currently unsolvable as we do not know if the semi-circle has a radius of 31 or 19.
Answer:
x=-1
Step-by-step explanation:
I'm weird and love these types of problems.
Ok first off we need to get x alone. To do that we need to first get rid of the 7.
We can do that by adding it because you have to use the opposite operation to get rid of it.
5x - 7 (+7) = -12 (+7)
See if you add -7 + 7 you get 0 which is why you have to use the opposite.
5x = -5
To get x alone you have to divide 5 because 5 is being multiplied by x.
5x(/5) = -5(/5)
x= -1
So x= -1

p = 5
T o find where the line crosses the y-axis let x = 0 in the equation and solve for y, hence
y = 0 + 5 = 5 → (0, 5 ) ← y -intercept
⇒ p = 5
