Answer:
0.84 square in
Step-by-step explanation:
Since the capacity of the cable is proportional to its cross-sectional area. If a cable that is 0.3 sq in can hold 2500 lb then per square inch it can hold
2500 / 0.3 = 8333.33 lb/in
To old 7000 lb it the cross-sectional area would need to be
7000 / 8333.33 = 0.84 square in
Answer:
22
Step-by-step explanation:
just add 8 to 14, then there is your number that would equal 14 if 8 was subtracted from it
200 - (2x) = 42
200 - 42 = 2x
158/2 = 2x/2
x = 79

Answer:
36 degrees
Step-by-step explanation:
since, m<AOB is a right angle, we shall just create an equation:
M<AOB+M<BOC=90 degrees
Substitute: 6z-12+3z+30=90
Solve: 6z+3x=9z
-12+30=18
so, 9z+18=90 degrees
-18 -18
9z=72
z=8
So if z=8, then we should fit it so that it matches measure of AOB.
6z-12
6 times 8=48
48-12= 36
1/4 an hour is 60 divided by 4 times 1 which is 15 minutes.
3/5 an hour is 60 divided by 5 times 3 which is 36 minutes.
15 plus 36 equals 51 minutes which is less than 1 hour.
