Answer:

These are two secant lines meaning we can use theorem 6-17 to find the value of x: 6x + 8x times 8x = 16 times 7

14x times 8x = 112

112x^2 = 112

x^2 = 1

x = 1

Answer:

x=1

Step-by-step explanation:

(whole secant) x (external part) =  (whole secant) x (external part)

(9+7) *7 = (6x+8x)*8x

16*7 = 14x*8x

112 =112 x^2

Divide by 112

112/112 = 112x^2/112

1 = x^2

Take the square root

1 =x

Roger brought some sponges. The number of packages he bought was 14 less than the number of sponges per package. Roger bought 51
mihalych1998 [28]

Answer:

the number of sponges per package bought be 32.5

Step-by-step explanation:

Let us assume the number of sponges per package be x

So the number of packages he bought be x - 14

And, the overall he bought 51 sponges

So

the number of packages of sponges did roger buy is

x + x - 14 = 51

2x = 51 + 14

2x = 65

x = 32.5

So the number of sponges per package bought be 32.5

Answer: Vector travelling 4 units to the left and 1 unit up, facing northwest.

Step-by-step explanation:

The original shape is ABC, while the translated shape is A'B'C'.

The translation is 4 units to the left and 1 unit up.

The correct vector will display as a vector travelling 4 units across and 1 unit down, facing northwest.

The first attached image travels 4 units across and 1 unit down, and faces the correct direction (northwest).

The second attached image travels 4 units across and 1 unit down, but it faces the wrong direction (southeast).

The third image travels 1 unit across and 2 units down. This is incorrect.

The fourth image travels 1 unit across and 2 units down. This is incorrect.

The correct answer is the first attached image (linked in comments)

A sphere has a volume of 457.3 in^3. What is the radius of the sphere?
Ne4ueva [31]

Answer:

\large\boxed{R\approx4.78\ in}

Step-by-step explanation:

The formula of a volume of a sphere:

V=\dfrac{4}{3}\pi R^3

R - radius

We have the volume V = 457.3 in³. Substitute:

\dfrac{4}{3}\pi R^3=457.3\qquad\text{multiply both sides by 3}\\\\4\pi R^3=1371.9\qquad\text{divide both sides by 4}\\\\\pi R^3=342.975\qquad\text{divide both sides by}\ \pi\\\\R^3=\dfrac{342.975}{\pi}\qquad/\pi\approx3.14/\\\\R^3\approx\dfrac{342.975}{3.14}\\\\R^3\approx109.2277\to R\approx\sqrt{109.2277}\\\\R\approx4.78\ in
