If he has 18 arrows and is shooting 3 at a time, divide, 18/3 = 6
He can shoot 6 times.
Answer:
Least common denominator of 2 and 8: 8
5 x 1 = 5
8 x 1 = 8
1 x 4 = 4
2 x 4 = 8
Step-by-step explanation:
5/8 and 1/2 are not equivalent; the wording is weird on this question, it almost makes it sound as if it wants you to make 5/8 and 1/2 equivalent fractions.
I assume it only wants you to set it up so that in part 2 you will be able to easily figure out how much wire Mr. Barber has used total. Which will be 9/8 yards, by the way. Alternatively, 1 1/8 yards.
(a) The vertical motion equation for the ball is h = 8 + 48t - 16t².
(b) The time for the ball to hit the ground is 3.15 s.
(c) The time for the ball to travel 56 ft above the ground is 0.79 s.
<h3>Vertical motion equation for the ball</h3>
The vertical motion equation for the ball is calculated as follows;
h = h₀ + vt - ¹/₂gt²
h = 8 + 48t - ¹/₂(32)t²
h = 8 + 48t - 16t²
<h3>Time for the ball to hit the ground</h3>
0 = 8 + 48t - 16t²
solve the above quadratic equation with formula method;
a = -16, b = 48, c = 8
t = 3.15 s
<h3>Time for the ball to be 56 ft above the ground</h3>
- let upward motion be positive
h = 8 + 48t + 16t²
56 = 8 + 48t + 16t²
0 = -48 + 48t + 16t²
solve the above quadratic equation with formula method;
a = 16, b = 48, c = -48
t = 0.79 s
