First find the amount of tax by multiplying 21 × 8.5%.
.085 × 21 = 1.785 = 1.79 (rounded)
Now add the tax back into the price...
21 + 1.79 = $22.79
Required percentage = (0.62 x 109482, 0.88 x 109,482) = (67879, 96,344)
Answer: It will land on the bush after 1.25 seconds.
First, we will start with what we are given the equation: h(t) = -16t^2 + 30
Now, we should input a 5 for the h(t) because we want the seconds that will give us a height of 5 seconds.
5 = -16t^2 + 30
Solve the equation:
0 = -16t^2 + 25
To solve this, you could use the quadratic formula or factor out a -1 and you will have the difference of two squares.
Either way the answer is 1.25 seconds.
well, like this the ratio is 300:250. We will now simplify these numbers.
30:25 (divide by ten)
6:5(Divide by five)
Your final ratio is 6:5
