540/6= 90
There will be 90 parcels.
Hope this helps!
I’d say 69 i could be wrong tho :) or it is 12 hope this helps
Some information is missing for #6.
#7: use sine, sin35=h/5.1, h=5.1*sin35, use a calculator, h≈2.9
#23: to find the reference angle, keep subtracting the number by 360, until the remaining difference is the smallest positive number.
1406-360-360-360=326. the reference angle is 326.
now look at the remainder, the terminal line of 326 degree is in the 4th quadrant between 270 and 360, the the reference angle is 360-326=34, the angle between the terminal line and the positive x axis. 34 is the answer.
Answer:
Step-by-step explanation:
y - (4 • (x + 5)2 - 7) = 0
Step 2 :
Equation at the end of step 2 :
y - 4x2 - 40x - 93 = 0
Step 3 :
Solving a Single Variable Equation :
3.1 Solve y-4x2-40x-93 = 0
The number of rotations made by the pulley in hour is 16 rotations
<h3>Data obtained from the question</h3>
Front the question given above, the following data were obtained:
- 97 degree rotation = 1 mimute
- Number of rotation in 1 hour =?
<h3>How to determine the time to rotate 360 degrees</h3>
We'll begin by calculating the time to rotate 360 degrees since a complete rotation has an angle of 360 degrees. This can be obtained as illustrated below:
97 degree rotation = 1 mimute
Therefore,
360 degrees = 360 / 97
360 degrees = 3.71 minutes
<h3>How to determine the number of rotations in 1 hour</h3>
- 1 rotation = 360 degrees = 3.71 minutes
- Number of rotation in 1 hour (60 minutes) =?
The number of rotation made in 1 hour (i.e 60 minutes), can be obtained as follow:
3.71 mins = 1 rotaion
Therefore,
60 mins = 60 / 3.71
60 mins = 16 rotations
Thus, the pulley will made an approximate of 16 rotations in 1 hour
