B
the volume (V) of a sphere = 
πr³
We require to know the radius r to calculate the volume
using surface area of a sphere = 4πr² = 615.752
divide both sides by 4π
r² = 
= 49.0248...
take the square root of both sides
r = 
≈ 7, hence
V= × π × 7³ = 1436.76 m³ → B
Answer: x = -11 ∠FGK = 30° ∠KGH = 150°
<u>Step-by-step explanation:</u>
∠FGK + ∠KGH = ∠FGH <em>Segment Addition Postulate</em>
x + 41 + x + 161 = 180 <em>Substitution</em>
2x + 202 = 180 <em> Simplify (added like terms)</em>
2x = -22 <em>Subtraction Property of Equality</em>
x = -11 <em>Division Property of Equality</em>
∠FGK = x + 41 = (-11) + 41 = 30
∠KGH = x + 161 = (-11) + 161 = 150
One way is subsitute
I like solving
so
what you do is this
add the equaitons to gether to eliminate x
2y=x+5
<u>3y=-x-3 +</u>
5y=0x+2
5y=2
y=2/5
sub back
2y=x+5
2(2/5)=x+5
4/5=x+5
minus 5
4/5-25/5=x
-21/5=x
the point is (x,y) or
(-21/5,2/5)
aprox
(-4.2,0.4)
I think they wanted you to read the garph you should have attached and guess the answer
the closes one is
hmm, x=-3
and y=1
so then D is the answer
Answer: 1
Step-by-step explanation:
Change in y/change in x
starting at y intercept. up 1 unit (change in y) and over 1 unit (change in x) to get to next point on line.
slope is 1/1 which reduces to 1.
