If y varies inversely as x and } = 3 when x = 4, then y
12 when x = 15.
Please select the best answer from the choices provided
True
or
False

Answers

Answer 1

Answer:

FALSE

Step-by-step explanation:

If y varies inversely as x., this is expressed as;

y = k/x

k is the proportionality constant

when y = 3 and x = 4

3 = k/4

k = 3 * 4

k = 12

when x = 15;

y = k/x

y =12/15

y = 4/5

Hence y is not equal to 12 when x = 15.

The correct answer is FALSE

10 cubic feets volume is equivalent to 25.85 inches.

Answer:

Option B

Step-by-step explanation:

Volume of a cube is:

[tex]A = s^3[/tex]

s - side length

All sides are the same length in a cube.

We are given the information that the total volume of the cube is 10 cubic feet.

[tex]10=s^3\\\\\sqrt[3]{10}=\sqrt[3]{s^3}\\\\\boxed{2.154435... = s}[/tex]

2.154435... ≈ 2.15

The approximate height of the cube is 2.15 inches.

Since the height of the shelf is 24 inches tall, the cube should be able to fit.

2.15 < 24

Option B should be the correct answer.

Hope this helps.

Alright,Alex let say we have factored a quadratic into two binomial, for example

[tex](5x + 3)(6x - 4)[/tex]

If we set both of those equal to zero

[tex](5x + 3)(6x + 4) = 0[/tex]

We can used the zero product property in this case to find the roots of the quadratic equation.

This means that

[tex]if \: ab = 0 \: then \: a = 0 \: and \: b = 0[/tex]

This means we set each binomal equal to zero to find it root.

[tex]5x + 3 = 0[/tex]

[tex]5x = - 3[/tex]

[tex]x = - \frac{3}{5} [/tex]

[tex]6x + 4 = 0[/tex]

[tex]6x = - 4[/tex]

[tex]x = - \frac{2}{3} [/tex]

So our roots are negative 3/5 and negative 2/3 using zero product property

How many 1 foot square tiles must be purchased to cover a 14 ft. by
11.5 ft. kitchen?

Answers

161 1-foot tiles.

EXPLANATION:

To find how many tiles we need,
We must find the area of the kitchen.

To find the area, you multiply
length x width

In this question,
the length is 14
the width is 11.5

14 x 11.5 is 161.

So 161 1-foot tiles to cover the kitchen.

Hope this helps! Have a gud day!

Answer:

61 tiles

Step-by-step explanation:

area = 14 x 11.5 = 61 ft²

each 1 foot square tile = 1 ft²

61/1 = 61 tiles

To get the percent discount

x = 36 - 30.96/36

x = 5.06/36

Triangle XYZ is shown on the coordinate plane below:
If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?

Answers

Answer:

Step-by-step explanation:

Triangle XYZ has been reflected across a line y = 1,

Therefore, line y = 1 will work like a mirror and all the distance of the points of the points from this line will be equal after the reflection about this line.

Distance of X from this line = 2 units

After reflection distance of X' from the line of reflection will be 2 units in opposite side.

Therefore, coordinates of X' will be (3, 3)
