12/x = 15/8
96 = 15x
x= 6.4 or 32/5
You will have to add 190 with 95 and that will be 285 because he rides 190 miles in FOUR days and you will need to know the half of 190 to get 2 days because each day he would ride 47.5 miles each day and 47.5+47.5=95.
The Answer is 285.
So it is a 1/26 chance of drawing c first. Then its the same chance for A and same chance for R. You multiply these fractions so the answer is 1/17576. If this is right could you possibly give me brainliest? Hope this helped.
When
the ball is in the ground, its height is basically equal to zero thus making
our equation,
<span> -16t^2 + 272t + 1344 = 0</span>
Simplifying
the equation will give us,
<span> - t^2 + 17t + 84 = 0 or t^2 – 17t – 84 = 0</span>
Factoring
out the equation will give us,
<span> (t – 21)(t + 4) = 0</span>
Thus,
t = 21 or t = -4. -4 is an extraneous root. Thus, the answer is t = 21.
<span>Answer:
21 seconds</span>
Answer: B
Step-by-step explanation:
First, simplify the main expression. The answer is 21.
Then simplify A. It is -106. That is not equal to 21 so A is wrong.
Then simplify B. That is 21. That means B is correct and you don’t have to solve C or D.
