Answer:
.173 seconds or a negataive
Step-by-step explanation:
Your formula would be
h = -16t^2 - 55t + 10
when it hits the ground h = 0
16t^2 + 55t - 10 = 0
t = (-55 ± √3665)/32 = .173 seconds or a negataive
Answer:
$16.60
Step-by-step explanation:
2.5x + 1.25(x - .20) = 31.25
2.5x + 1.25x - .25 = 31.25
3.75x - .25 = 31.25
3.75x = 31.25 + .25
3.75x/3.75 = 31.50/3.75
x = 8.40
y = x - .20
y = 8.20
1x + 1y = 16.60
Answer:
The answer to the equation is: 4.648
Answer:
x=5/2
Step-by-step explanation:
We can use ratios of similar triangles to help solve the problem.
side x 5
-------- = --------------- = ---------------
hypotenuse 4 8
Using cross products
x*8 = 4 * 5
8x = 20
Divide each side by 8
8x/8 = 20/8
x = 5/2
