The surface area of a sphere is 4r^2pi, so dividing 100 by 4pi gives a result of 25/pi. Taking the square root and rationalizing the denominator, we have 5sqrt(pi)/pi as the radius of the sphere.
Answer: I can’t solve (x+2)^2/64+(y-1)^2/81=1 but I solve (x+2)^2/64+(y-1)^2/81 it the same thing but I take out the =1
Step-by-step explanation: look at the picture and you see me answer, hope this help:)
Answer:
-30
Step-by-step explanation:
I'm assuming the equation is
. If it is not please tell me.
If we know the values of m and n, we can just substitute inside the expression.

Hope this helped!
Let the number be x.
6x-20=94
6x=114
x=19
Answer:
-5/3
Step-by-step explanation:
Parallel lines are lines which have the exact same slope but different y-intercepts. We can find the slope by converting to slope-intercept form, y=mx+b from standard form.
We convert by using inverse operations to isolate y.
5x+3y=7
5x-5x+3y=7-5x
0x+3y=-5x+7
3y=-5x+7
.
The slope is -5/3. SInce parallel lines have the same slope, the slope for a parallel line will be -5/3.
