Answer:

33,493.33 cubic units

Step-by-step explanation:

We are given that a sphere has a radius of 20 units and we are to find the volume of this sphere.

We know the formula for the volume of a sphere:

Volume of a sphere = $\frac{4} {3} \pi r^3$

Substituting the given value of radius in the above formula:

Volume of sphere = $\frac{4}{3}$ × $3.14$ × $20^3$

= 33,493.33 cubic units

Somebody help with this please

Covert standard form to slope-intercept form
4x + 7y + 3 = 0
7y = -4x - 3

y = (-4/7)x - 3/7 so the slope of this line is -4/7

The slope perpendicular to this is - 1 (-4/7) = 7/4
The required line has equation:-
y - 1 = (7/4)(x - (-2))
y - 1 = (7/4)x + 14/4
y = (7/4)x + 18/4 That is the answer in slope intercept form

Multiply through by 4

4y = 7x + 18

7x - 4y = 18 in Standard form Answer

1..) 2x +15 = 35

Masja [62]

Answer:

1) $x=10$

2) $x=3$

Step-by-step explanation:

$2x+15=35$

Subtract 15 from both sides

$2x=20$

Divide both sides by 2

$x=10$

$2(10)+15=35$

$20+15=35$

$35=35$

this shows that 10 is the right answer

$7x-3=18$

Add 3 to both sides

$7x=21$

Divide both sides by 7

$x=3$

$7(3)-3=18$

$21-3=18$

$18=18$

this shows that 3 is the right answer

Hope this helps

Solve for x. -2(x-7)=16

solniwko [45]

Answer:

-1

Step-by-step explanation:

-2(x-7)=16

-2x +14=16 You distribute

-14 -14

-2x = 2

-2 -2 you divide

and get -1 as your answer.

Hope my answer has helped you!
