Hope this helps
<ACE= 31 degrees
<ADB: 41 degrees
<AFE: 70 degrees
<ehd: 100
Step-by-step explanation:
We know that the volume of a sphere is:
V
=
4
3
π
r
3
where
r
=
10
2
=
5
ft
is the radius;
we need half of this, so we use:
V
2
=
2
3
π
r
3
=
261.8
ft
3
giving a total weight of water of:
W
=
261.8
⋅
62.4
=
16
,
336
pounds
Answer:
4=m4-1
Step-by-step explanation:
This is because you're using gas so you're slope of the equation will have to be negative. If correct please mark brainliest. thx
For x^2-49
this is a diffarence of two perfect squares. I suggest that this is memorised.
a^2-b^2=(a-b)(a+b)
so x^2-7^2=(x-7)(x+7)
so to solve x^2+x-56 you want to find out what two numbers add to 1 and multiply to make -56
since -56 is negative we know that the two number are difarent signs so that eliminatess answers B and D.
if we try answer C -8+7=-1 so the answer is not C because we want +1 not -1
then we see that 8+(-7)=1 so the answer is A
