Answer:  14

<u>Step-by-step explanation:</u>

Consecutive even numbers would be {2, 4, 6, 8, 10, ...}

Let x represent the smallest number, then x + 2 is the middle number and x + 4 is the largest number.

1st number: x

2nd number: x + 2

3rd number: x + 4

1st number + 2nd number + 3rd number = Sum

      (x)        +      (x + 2)       +      (x + 4)      =  48

                                                      3x + 6   =  48

                                                      3x          = 42

                                                        x           = 14

1st number: x           ⇒ x = 14

2nd number: x + 2   ⇒ 14 + 2 = 16

3rd number: x + 4    ⇒ 14 + 4 = 18

<u>Check:</u>

14 + 16 + 18 = 48 \checkmark

Surface area of a sphere is 615.752 m2, what is the volume of the sphere?
const2013 [10]

B

the volume (V) of a sphere = \frac{4}{3} 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 = \frac{615.752}{12.56} = 49.0248...

take the square root of both sides

r = \sqrt{49.0248..} ≈ 7, hence

V= \frac{4}{3} × π × 7³ = 1436.76 m³ → B

Two segments  that are tangent to a circle from the same external point are of equal length.
9)   2x²=8x
2x²-8x=0
x(2x-8)=0
x=0,
2x-8=0
x=4  can be
2*4²=8*4=32

10)  y=y²/7
y²/7- y=0
y(y/7 -1)=0
y=0,
y/7 - 1=0
y/7=1 
y=7 can be
y=y²/7= 7

I need help with these two questions and for number 15 it's just two of them not three.​
andrezito [222]

This looks simple...for 14 the perimeter is x+3+x+3+2x-1+2x-1. Simplified is 6x+6-2. Which is 6x+4.

Thank me if it looks right!

For 15...2y+3+2y+3+x+3+x+3...Which is 4y+12+2x.
