Answer:
5+(3x+6)/5+x for x=-3
5+(3(-3)+6)/(5+(-3)) = -15/2
Step-by-step explanation:
You would have to replace the given number (x) in the equation and just do the math .
Answer:
P(B | A) = 0.80
Step-by-step explanation:
For independent events A and B, P(B | A) = P(B)
Therefore, P(B | A) = 0.80
Answer:
24
Step-by-step explanation:
400 × 12 = 4,800
4,800 needed for ONE coat.
Since you need TWO coats, double 12, then you should get 24.
For this, we can set up a proportion.
Their aim was 15000, so if they raised 100% of their goal, they wouldve raised exactly 15000.
They raised 557%, so how much did they make?
Proportion:
$15000 100%
$x 557%
Our expression would be x=$15000*557% divided by 100%, which would be $83550, so... a lot of money.
(we did an “x” formation with the proportion, ie “connected” x with 100, and “connected” 15k and 557. The number connecting to x is what we divide the equation by, and the other two are multiplied and then divided by the first number connecting to x. Otherwise we couldve calculated 557% of 15000 and gotten the same result. Whichever way is easier for you :) )
Answer:
Reaches a maximum height of 235.00 feet in 3.75 seconds.
Step-by-step explanation:
The height of the boulder, h, in feet after t seconds is given by the function is given by :
.....(1)
For maximum height, put 
i.e.

Put t = 3.75 in equation (1). So,

So, the boulder's maximum height is 235 feets and it takes 3.75 s to reach to its maximum height.
