Y = 6x
Illusion [34]
<span> Not to worry, Anarkee, it's easy. They just dress it up in tech-speak. What it means is "For what pair of numbers in the list is the statement "Y = 6x" true, if the first number is x and the second is y".

You will notice that in every pair, one number is 6 times the other, but if the numbers are arranged as ORDERED pairs, the convention is that x comes before y. therefore only B, C and E satisfy the equation.

Simple but sneaky, huh? </span>

RST has vertices R(0,0), S(10,5), and T(5,-5). R’S’T’ is the image of RST after a dilation with center (0,0) and scale factor 1/
AysviL [449]

The coordinates of the point S' is (2,1)

Explanation:

Given that the RST has vertices R(0,0), S(10,5) and T(5,-5)

The image R'S'T' is the image of RST after a dilation with center (0,0) and scale factor \frac{1}{5}

We need to determine the coordinates of the point S'

The coordinates of S' can be determined by multiplying both the x and y - coordinates of the point S with the scale factor \frac{1}{5}

Let us consider the x - coordinate of the point S and multiply it with the scale factor \frac{1}{5}

Thus, we have,

x - coordinate of the point S' is given by

10 \times \frac{1}{5}=2

Thus, the x - coordinate of the point S' is 2

Similarly, the y - coordinate of the point S' can be determined by multiplying the point S with the scale factor \frac{1}{5}

Thus, we have,

The y - coordinate of the point S' is given by

5\times\frac{1}{5}=1

Thus, the y - coordinate of the point S' is 1

Hence, the coordinates of the point S' is (2,1)

The length of a rectangle is 5 m greater than the width. The perimeter is 150 m. find the width
Elza [17]

P = perimeter

Perimeter of a rectangle = l + l + w + w

or  P = 2l + 2w

You know:

P = 150 m

l = w + 5     [length is 5 m greater than the width]

P = 2l + 2w        Plug in what you know

150 = 2(w + 5) + 2w     Simplify, distribute/multiply 2 into (w + 5)

150 = 2w + 10 + 2w

150 = 4w + 10     Subtract 10 to both sides of the equation

140 = 4w       Divide 4 on both sides

35 = w

PROOF               l = w + 5 --->  l = 40

P = 2l + 2w

150 = 2(40) + 2(35)

150 = 80 + 70

150 = 150

A sphere is inscribed in a cylinder. Use complete sentences and geometric formulas to compare the surface area of the sphere and
grandymaker [24]

Answer:

1 : 1

Step-by-step explanation:

When a circle is inscribed in a cylinder, the height of the cylinder is equal to the diameter of the sphere and the radius of the cylinder is same as that of the sphere.

Let the radius of sphere is r.

height of cylinder, h = 2r

radius of cylinder = r

Surface area of sphere, A = 4πr²

lateral surface area of cylinder, A' = 2 πrh

A' = 2πr x 2r = 4πr²

The ratio of surface area of sphere to the lateral surface area of cylinder is 1 : 1.
