8 - ? = -1. the missing number would be 9.
Answer:
35 m/s
Step-by-step explanation:
Let gravitational acceleration g = 9.8m/s2. We can calculate the amount of time for the ball to fall vertically a distance of 1.6 m
This is also the time it takes for the ball to fly horizontally, assume constant horizontal speed, we can calculate the speed it takes to travel across 20m in 0.571s
v = 20 / 0.571 = 35 m/s
Z=82 vertical or opposite angle theorem
15x-7 + 82=180 supplementary angles theorem
so 15x +75 =180
15x=180-75
x=105/15
x=7
Answer:
the expected total amount of time in minutes is 88.4
Step-by-step explanation:
The computation of the expected total amount of time in minutes is given below:
= Standard deviation × needed to answer calls each day
= 1.7 × 52
= 88.4
hence, the expected total amount of time in minutes is 88.4
Can you please attach a photo or put up answer choices? It would help a lot. Thanks.
