Fay has a lemonade stand.
She spends £42 on ingredients.
She sells each glass of lemonade for £1.50.
If she sells 30 glasses of lemonade, what is her total profit?

Answers

Answer 1

Answer:

her total profit is 3

Step-by-step explanation:

1.50 x 30 = 45

to find total profit - 45-42= 3

Answer 2
Her total profit would be £3.
£1.50 multiplied by 30 glasses equals £45
You then subtract £45-£42 to get £3 profit.
Hope that helped!

Answers

Answer:

C. 24

Step-by-step explanation:

Q is the centroid of the triangle. This means that the interior lines are medians, the special rule for medians when they intersect within a triangle is that each line is split into exactly 2/3s and 1/3. So the side of the median closer to the vertex will be exactly double the shorter side. Therefore, if AD is 36, find 2/3s of that to get AQ. An easy way to do this is to divide 36 by 3, which is 12, and then multiply that by 2, which gives you the final answer, 24.

Find p(–4) if p(x) = 3x^3 – 2x^2 + 6x – 4



If r(x) = x^3 – 2x + 1, find r(2a^3).

Answers

Answer:

I think that the first part would be -252, but I'm not sure about the second part

Step-by-step explanation:


Find p(–4) if p(x) = 3x^3 – 2x^2 + 6x – 4

p(-4) = 3x^3 – 2x^2 + 6x – 4

p(-4) = 3(-4)^3 – 2(-4)^2 + 6(-4) – 4
= 3(-64) - 2(16) + 6(-4) - 4
= -192 - 32 - 24 - 4
p(-4) = -252


r(x) = x^3 – 2x + 1, find r(2a^3)

r(x) = (x^3 – 2x + 1) (2a^3)
= (2a^3) x^3 + (2a^3) (-2x) + (2a^3) * 1
= x^3 (2a^3) - 2x (2a^3) + 1 * (2a^3)
r(x) = 2a^3x^3 - 4a^3x + 2a^3

Answer:

2 = 18

4 = 9

6 = 6

8 = 4.5

10 = 3.6

12 = 3

14 = 2.57 (2.6 simplified)

16 = 2.25 (2.3 simplified)

Step-by-step explanation:

You can solve this by dividing 36 (the whole amount of meter of fences)

by each number of the length

area                    width

36 divided by 2 = 18

36 divided by 4 = 9

36 divided by 6 = 6

36 divided by 8 = 4.5

36 divided by 10 = 3.6

36 divided by 12 = 3

36 divided by 14 = 2.57 (2.6 simplified)

36 divided by 16 = 2.25 (2.3 simplified)

O X'(1, 3), Y'(0, 0), Z'(-1,3)
O X'(1, -3),Y (0, 0), Z'(-1, -3)
O X(-3, 1), Y'(0, 0), Z'(-3,-1)

Answers

Answer:

Step-by-step explanation:

Transformation involves changing the vertices of a shape

The correct set of image points for triangle X'Y'Z is X'(-3,1), Y'(0, 0), Z'(-3,-1)

The vertices of the triangle are given as:

X(-1, -3), Y(0, 0), and Z(1, -3)

The rule of rotation is given as: 90 degrees rotation about the origin.

This is represented as:

[tex](x,y) \to (y, -x)[/tex]

So, we have:

X'(-3,1), Y'(0, 0), and Z'(-3,-1)

Hence, the correct set of image points for triangle X'Y'Z is X'(-3,1), Y'(0, 0), Z'(-3,-1)
