Answer:
2,160 seconds
Step-by-step explanation:
Since, the angle between the machine and angle of press is 
as shown in the attached image.
Therefore, the actual weight lifted by the power lifter is given by 
where 'w' stands for the weight being lifted and 
is the angle of press.
Now,
actual weight lifted by the power lifter = 
= 
pounds.
Answer:
<h3>132°</h3>
Step-by-step explanation:
If line PS has midpoint a Q and ray QR, then line PQS will be a straight line and <PQR + <RQS = 180 (sum of angle on a straight line).
Given
<PQR = 3x-6
<RQS = x+ 2
To get x, we will use the relationship above;
3x-6+x+2 = 180
4x-4 = 180
add 4 to both sides
4x-4+4 = 180+4
4x = 184
x = 184/4
x = 46
Since <PQR = 3x-6, we will substitute the value of x into the formula;
<PQR = 3x-6
<PQR = 3(46)-6
<PQR = 138-6
<PQR = 132°
Hence the size of angle PQR is 132°
Answer:
Theres no picture...
Step-by-step explanation:
21.5 means 21 and 5 tenths and is read that way.
21.5 = 21 5/10 =(21*10 + 5) /10 = 215/10 = 43/2 in simplest terms
