In a fruit punch you mix 150 ml of lemonade with 250 ml of fruit juice. Write the ratio of the volume of lemonade to the volume of fruit juice. Give your ratio in its simplest form.

Answers

Answer:the ratio of the volume of lemonade to the volume of fruit juice in simplest form = 3:5

Step-by-step explanation:

Volume of lemonade in the mixture = 150ml

Volume of fruit juice in the mixture = 250ml

Ratio of the volume of lemonade to the volume of fruit juice= 150ml: 250ml

and reducing to the simplest form , we have

150:250

dividing both by 10 gives

15:25

dividing both by 5 gives

3:5

Therefore  the ratio of the volume of lemonade to the volume of fruit juice in simplest form = 3:5

Answers

Answer:

y = 1/3x

Step-by-step explanation:

Solve for x
14x + 2 = 9x - 3

Answers

-9x from both sides
5x+2=-3
-2 from both sides
5x=-5
x= -1

Answer:

[tex]x=-1[/tex]

Step-by-step explanation:

1) Subtract 9x from both sides.

[tex]14x+2-9x=-3[/tex]

2)  Simplify  14x+2-9x to 5x+2.

[tex]5x+2=-3[/tex]

3) Subtract 2 from both sides.

[tex]5x=-3-2[/tex]

4) Simplify  -3-2 to  -5.

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

5) Divide both sides by 5.

[tex]x=-1[/tex]

Therefor, the answer is x = -1

Helen goes into a shop.
She wants to buy 2 shirts and a pair of shorts,
Each shirt costs £24.50
The pair of shorts costs £18.90
Helen only has £70 to spend,
Does Helen have enough money to buy the 2 shirts and the pair of shorts?

Answers

Step-by-step explanation:

2*24.50=49 (two shirts)

18.90 (pair of shorts)

49+18.90=67.90

she can spend 70, means she can buy all of those and she still has 2.10

Three students have already enrolled for a creative writing class. The teacher will cancel the class if there are fewer than 10 students enrolled. Write three values for numbers of students needed to sign up so that the the creative writing class can be held

Answers

Answer:

7, 10 and 15

Step-by-step explanation:

Given

[tex]S_1= 3[/tex]  --- Students already enrolled

[tex]Total = 10\ (less)[/tex]

Required

Determine the additional number of students needed for the teacher not to cancel the class

First, we need to calculate the number of students for the teacher to cancel the class.

Represent this with x.

So, we have:

[tex]S_1 + x < Total[/tex]

Make x the subject

[tex]x < Total - S_1[/tex]

Substitute values for Total and S1

[tex]x < 10 - 3[/tex]

[tex]x < 7[/tex]

This means that if less than 7 additional students come to the class, the teacher will cancel the class.

So, for the teacher not to cancel the class, the students must be 7 or greater (i.e. 7, 8, 9, 10....)

Answers

Answer:

See below

Step-by-step explanation:

Filling in the table using the function, substitute t for each line:

5        |   372.5      

10       |   495

Jonny and Faheem share some money in the ratio 3:5. Faheem gets £12 more than Jonny. How much does Jonny get?

Answers

Given:

Jonny and Faheem share some money in the ratio 3:5.

Faheem gets £12 more than Jonny.

To find:

The amount that Jonny gets.

Solution:

Jonny and Faheem share some money in the ratio 3:5.

Let Jonny and Faheem get 3x and 5x.

Different between their amounts is

[tex]5x-3x=2x[/tex]

Faheem gets £12 more than Jonny. It means the difference between their amounts is equal to £12.

[tex]2x=12[/tex]

[tex]x=\dfrac{12}{2}[/tex]

[tex]x=6[/tex]

The amount that Jonny gets is

[tex]3x=3(6)[/tex]

[tex]3x=18[/tex]

Therefore, Jonny gets £18.

can someone answer my question????? pls this is already missing i’ll give brainlist and points don’t ignore

Answers

Reminder: y = mx + b, to isolate y, you would need to subtract mx value, and what you do to one side, you do to all. If there’s a coefficient in front of your y value, you then divide the equation by that coefficient. Once y is isolated, m and b values are easier to find.

Answer:

1) y = -2x + 1 // m = -2, b = 1

2) y = 5/8x - 1 // m = 5/8, b = -1

3) y = 7/8x - 3/4 // m = 7/8, b = -3/4

4) y = 3/4x + 4 // m = 3/4, b = 4
