Answer:
900π m2
Step-by-step explanation:
surface are of a sphere is 4π(r)^2
now diameter is 30m,so radius will be 15 m
how, 4π(15)^2=900π (m2)
Answer:
0.960
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
-2x - 3 = 9
+ 3 +3
-2x = 12
/ -2 / -2
x = -6
The range would be between 2000 and 3000 PSI.
Explanation:
2500 PSI - 500 PSI = 2000 PSI
2500 PSI + 500 PSI = 3000 PSI
Hope this helps :)
Answer:
Step-by-step explanation:
I still suspect that Angle A is 30° and Angle B is 60°. Otherwise the labels do not fit the illustration.
If Angle A is 60°, as you insist, then the solution (the length of x) is as follows:
opp side x
tan 60° = √3 = ---------------- = -----
adj side 7
Then:
√3 x
----------- = -----
1 7
Thru cross-multiplication we see that x = 7√3
Multiply both sides by 7, which produces:
7√3 = x
