Answer:

Step-by-step explanation:


Based on the Roni using a lawn mower and Allie pushing one, Roni would be able to mow 0.71 of the field.
<h3>How much of the field would Roni mow?</h3>
Assume that the part of the field that Roni would mow is x.
The relevant equation would be:
x/30 + x/75 = 1
5x/150 + 2x/150 = 1
7x / 150 = 1
x = 21.43
In 30 minutes, Roni would have mowed:
= 21.43 / 30
= 0.71
Full question is:
Roni and Allie are mowing the grass at the soccer field. Roni has a riding lawn mower and can mow the field in 30 minutes. Allie is pushing a lawn mower and can mow the field in 75 minutes.

Answer:
The value of Cos(01) is 0.866 or √3/2
Step-by-step explanation:
In this question, we are asked to calculate the value of cos (01) given the value of sin(01)
Now, given the value of sin (01), we can calculate the value of cos (01).
To get the value of 01, we simply find the value of the arc sin 01
Mathematically since sin (01) = 1/2
(01) = arc sin (1/2)
(01) = 30 degrees
Now since 01 = 30 degrees
cos 01 = Cos (30) = 0.8666 or simply √3/2
