Answer:
Im in 7th grade and I need some help on a math problem. can I post it?
Use the formula for the perimeter.
P = 2l + 2w
Substitute
258 = 2(74) + 2w
Solve for w
258 = 2(74) + 2w
258 = 148 + 2w
110 = 2w
/2 /2
55 = w
Therefore the width is 55 yards.
Proof: 55 + 55 + 74 + 74 = 258
Linear velocity is given by the formula v = ωr, where ω is the angular velocity in radians, and r is the radius.
We first solve for ω:
11 revs/sec = (11 revs/sec) x (2πrad/rev) = 22π rad/sec.
(note: 2πrad/rev means that there are 2π radians in one revolution)
v = ωr; where v is in meters per second
v = (22π rad/s)(7.2 cm)(10⁻² m/1 cm) = 4.976 m/s
If it is a parallel line and it is on the same side it’s the same as the other angle so 34 degrees
