Answer:

£32.60

Step-by-step explanation:

Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1. Apple juice costs 56p for a 1-litre carton. Mango juice costs £1.20 for a 1-litre carton.

A pack of 80 plastic cups costs £1. Nita sells her fruit drink at a school concert in 250ml cups for 60p each.

We are told that Nita sells all her 80 cups

100 pence = £1

60p =

= 60/100

= £0.6

Hence, the selling price =

£0.6× 80

= £ 48

Profit = Selling Price - Cost Price

We have to find the Cost Price

A pack of 80 plastic cups costs £1.

Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1.

3 + 1 = 4

1 liter = 1000ml

For Apple Juice

3/4 × 1000ml = 750ml

For Mango Juice

= 1/4 × 1000ml = 250ml

This means she uses a mixture of 750 ml of Apple juice and 250 ml of Mango juice

Apple juice costs 56p for a 1-litre carton.

£0.56 = 1 liter = 1000ml

1000ml = £0.56

750 ml =

= 750 × 0.56/1000

= £0.42

Mango juice costs £1.20 for a 1-litre carton.

1000ml = £1.20

250 ml = x

x = 250 × 1.20/1000

= £0.3

Hence, the total cost for 1000ml of mixed juice = £0.3 + £0.42

= £ 0.72

We are told the content of each cup = 250 ml

For 80 cups she would need

80 × 250 ml

= 20000ml of the mixed juice

If 1000 ml = £0.72

20000ml = x

x = 20000 × £ 0.72/1000

x = £14.4

1 pack of 80 cups cost £1

Hence: £14.4 + £1

Cost Price = £15.4

Profit = Selling Price - Cost Price

Profit = £48 - $15.4

Profit = £32.60

Therefore, the money she gives to the school fund is £32.60

Answer:

H0: ρ= 0 against Ha : ρ≠0

Step-by-step explanation:

The null hypothesis would be the weight gains of a sample of lambs on regular feed is equal to the weight gains of the sample that receives an additional niacin supplement against the claim that the weight gains are not equal .

H0: ρ= 0 against Ha : ρ≠0

Type 1 Error would be when the H0 is true and there's no difference but H0is rejected or Ha is accepted that there is difference in the weight gains.

Type 2 Error would be when the Ha is true and there is difference but Ha is rejected or H0 is accepted that there's no difference in the weight gains.

The appropriate conclusion would be Ha is accepted and H0 is rejected fail to reject.

A confounding variable is the one which effects the results . It is the biased variable which should be identified and ignored.

For example in this experiment the independent variable would be the amount of the supplement the dependent would the weight gain but the gender of the sheep is the confounding variable. It is not directly related to amount of supplement .

1) gender of sheep

2) the breed of sheep

3) the number of sheep

4) the height of sheep

Answer:

average speed = total distance travelled÷ total time taken

distance 120 km

time is 1 hr and 20 minutes

from 0700 t0 0820

1hr = 60 minutes

= 20 minutes

1/3 hr

total time is 1 1/3 hr

speed = 120/ 1 1/3

= 120 * 3/ 4

= 90 km/ hr

Step-by-step explanation:

Answer:  x = 3130/3 = 1043.333

Step-by-step explanation:   Solve  :    -3x+3130 = 0  

Subtract  3130  from both sides of the equation :  

                     -3x = -3130

Multiply both sides of the equation by (-1) :  3x = 3130

Divide both sides of the equation by 3:

                    x = 3130/3 = 1043.333

Answer:

[tex]3125=5-10+3x\quad :\quad x=\frac{3130}{3}\quad \left(\mathrm{Decimal}:\quad x=1043.33333\dots \right)[/tex]

[tex]3125=5-10+3x[/tex]

[tex]\mathrm{Switch\:sides}[/tex]

[tex]5-10+3x=3125[/tex]

432 people rode the roller coaster in the third hour.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

182 people rode the roller coaster.

307 people rode the roller coaster.

A total of 921 people had ridden the roller coaster.

So, Number of people rode the roller coaster

= 921 - 182 - 307

= 432

Answer:

Step-by-step explanation:

Here is the complete question.

A wire is first bent into the shape of a triangle. Each side of the triangle is 24in long. Then the wire is unbent and reshaped into a square. What is the length of a side of the square?

A triangle have 3 sides. If each sides is 24in long, the perimeter of the triangle will be:

P = s1 + s2 + s3

P = 24in + 24in + 24in

P = 72in

If the same length of wire is unbent and reshape into a square, this means:

Perimeter of the triangle = Perimeter of the square

Perimeter of the square = 72in

To get the length of a side of a square, we will use the formula:

Perimeter of a square = 4L

72 = 4L

L = 72/4

L = 18in

Hence the length of a side of the square will be 18in.

Answer:

4.12 PM

Step-by-step explanation:

Radio station 1 : Plays the song every 18 minutes

Radio station 2 : plays the song every 24 minutes

Both stations play the song at 3:00 PM.

When is the next time the stations will play the song at the same time?

Find the lowest common multiple of 18 and 24

18 : 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270

24 : 48, 72, 96, 120, 144, 168, 192, 216

The lowest common multiple of 18 minutes and 24 minutes is 72 minutes

72 minutes = 1 hour 12 minutes

Add 1 hour 12 minutes to 3:00 PM to know when both radio station will play the song at the same time

= 3.00 PM + 1 hour 12 minutes

= 4.12 PM

Answer: The scale used by Sarah is 1 to 43.2 inches ( drawing to actual)

Step-by-step explanation:

Here, we want to know the scale used for the drawing of the Dinosaur by sarah.

The actual height of the Dinosaur is 9 feet, but in her drawing she represented the height by 2.5 inches( 2 1/2 is same as 2.5 inches)

Mathematically, we know that 1 foot is 12 inches;

So the actual height of the Dinosaur is 9 * 12 = 108 inches

So practically, what she has done is to represent a height of 108 inches by 2.5 inches

So the scale factor used will be;

108/2.5 = 43.2

The scale used is 1 to 43.2 or simply 1:43.2 to represent the drawing to the actual

The value of x is 5

Step-by-step explanation:

Let us simplify each side at first

∵ 2(x - 3) = 4(x - 4)

∴ 2(x) - 2(3) = 4(x) - 4(4)

∴ 2x - 6 = 4x - 16

→ Subtract 4x from both sides

∴ 2x - 4x - 6 = 4x - 4x - 16

∴ -2x - 6 = -16

→ Add 6 to both sides

∴ -2x - 6 + 6 = -16 + 6

∴ -2x = -10

→ Divide both sides by -2

∴ [tex]\frac{-2x}{-2}=\frac{-10}{-2}[/tex]

∴ x = 5

∴ The value of x is 5

Question 1: 78 = angle 2.

Question 2: 7 = angle 2.

Step-by-step explanation:

Complementary deals with the angles adding up to 90 degrees.

So, do 90 - 12, which equals 78.

78 = angle 2.

90 - 83 = 7.

7 = angle 2.
