Answer:

y = 5

Step-by-step explanation:

2y - 3.5 = 6.5

Add 3.5 to both sides.

2y = 10

Divide both sides by 2.

y = 5

Let's say Olive oil = O, Balsamic Vinegar = B, Salad Dressing = S

For the salad dressing she uses 3 parts olive oil to 2 parts balsamic vinegar

So we can say for every 3 ml of olive oil, she needs 2ml of balsamic vinegar

We know she has 120ml of olive oil, so first step is to find how much balsamic vinegar she will be using.

Remember, for every 3 ml of Olive Oil, she needs 2ml of Balsamic Vinegar .

if you do 120 divided by 3 = 40

So she is making 40 times the amount of salad dressing.

This means you need to multiply the  amount of balsamic vinegar by 40.

B = 40 times 2 = 80 ml

So now for the dressing we know :

She uses 120 ml of olive oil and 80 ml of balsamic vinegar.

So to find how many ml of salad dressing she can make, you just add the two.

S = O + B = 120 + 80 = 200 ml

Using proportions, it is found that she can make 80 milliliters of salad dressing.

The rule of three is:

3 parts of olive oil - 2 parts of balsamic vinegar.

120 ml - x ml

Applying cross multiplication:

[tex]3x = 2(120)[/tex]

[tex]3x = 240[/tex]

[tex]x = \frac{240}{3}[/tex]

[tex]x = 80[/tex]

She can make 80 milliliters of salad dressing.

Answer:

38.28

Step-by-step explanation:

ok so one of the sides don't count because the circle is there. so that leaves us with 14 + 14 + 4= 32(my bad)

then the circumference is for half the circle. and when finding the circumference you use radius so 2 cm. 2 x 3.14 x 2 = 12.56

then divide it by 2- 6.28

so that gives us 38.28

Step-by-step explanation:

Answers:

x=4 and y=27

x=8 and y=-1

x=1 and y=216

Step-by-step explanation:

You have to plug all of the choices given into the equation until it equals to 7

∛12 + 3 = 2.9 +3 = 5.29

∛27 + 4= 3 + 4 = 7

∛16 + 3 = 2.5 +3 = 5.5

∛-1 + 8 = -1 + 8= 7

∛216 + 1 = 6 + 1= 7

∛30 - 3 = 3.11 - 3 = 0.11

∛3 + 4 = 1.44 + 4= 5.44

Answer:

China produced 18% of the world's wheat yield in 2015.

Step-by-step explanation:

To determine the percentage of the world's wheat yield China produced in 2015, we will divide the quantity of wheat China produced by the total quantity of wheat produced globally and then multiply by 100%.

From the question,

Wheat produced globally in 2015 = 734.1 million tons

Wheat produced by China in 2015 = 130.2 million tons

Percentage of the world's wheat yield China produced in 2015 =

(130.2 million tons / 734.1 million tons) × 100%

= 0.17736 × 100%

= 17.736%

= 18% ( to the nearest whole number)

Hence, China produced 18% of the world's wheat yield in 2015.
