Answer:
The muscular work completed by four men will be 2400 ft. lbs.
Step-by-step explanation:
See the diagram of the ramp.
Four men carry 20 boxes each up a ramp as shown.
So, 4 men carry total (4 × 20) = 80 boxes up the ramp and each box weighs 5 pounds.
Then, the 4 men carry total (80 × 5) = 400 lb weight up the ramp.
Now, the vertical height of the ramp from the ground level is 6 ft.
Hence, the muscular work completed by four men will be (400 × 6) = 2400 ft. lbs. (Answer)
Answer:
<h3>B. m<3 = m<6 = 75degrees</h3>
Step-by-step explanation:
First you must understand that in geometry, the alternate interior angles are equal
Hence if ∠3 and ∠6 are alternate interior angles, then <3 = <6
Given that m<3 = 75 degrees
m<6 will also be 75 degrees since both angles are equal
Answer:
Step-by-step explanation:
These are logically difficult, so it makes sense to me you're asking about this.
so A = 1/2 (big arc - small arc)
and 360 = big arc + small arc
then
360 - small arc = big arc
so rewrite the top equation
A = 1/2(360-small arc -small arc)
63 = 1/2( 360 - 2 small arc)
2* 63 = 360 - 2 small arc
126 = 360 - 2 small arc
2 small arc = 360-126
2small arc = 234
small arc = 234/2
small arc = 117
x = 117°
Answer:they are both linear because Their slopes are constant.
