Answer:
The answer is A $100
Step-by-step explanation:
since 0 deposits is $50 and 1 deposit is $150
you do 150-50 which is 100
<span>3.19459 seconds
Since we've been given the equation for how high the ball is at t seconds, all we need to do is solve for a height of 0. So
h = 67 - 5t - 5t^2
0 = 67 - 5t - 5t^2
And you should immediately notice that we have a quadratic equation with A = -5, B = -5, and C=67. Use the quadratic formula to determine the roots of -4.19459 and 3.19459. Since we can't have negative seconds, that means that the ball will hit the ground 3.19459 seconds after it was thrown.</span>
Answer:
the answer is C
Step-by-step explanation:
using her first part 2 kilometers in 18 minutes
total kilometers - 2
and total time - 18
so you would get:
k – 2 = (t – 18)
Answer: I think B
Step-by-step explanation:
So we need to divide 
km by 8 people. Let's set this up:
÷ 
When we divide fractions, we need to flip the second term and change the division sign to a multiplication sign:
Then we multiply straight across:
So now we know that the amount of road that each person should be assigned is 
km.
