Answer:

3 : 2

Step-by-step explanation:

We are asked to calculate as a ratio 9 nickels to 3 dimes reduced to lowest terms.

One nickel means $0.05 and one dime means $0.10.

So, 9 nickels is equal to $(0.05 × 9) = $0.45

And 3 dimes is equal to $(0.10 × 3) = $0.30

Therefore, the ratio will become 0.45 : 0.30 ≡ 3 : 2 (Answer)

Muffins baked by Andrea=h muffins
Muffins baked by Violet =h-8

Average=(Total sum of numbers)/(Number of items)
total sum=h+(h-8)=2h-8
Number of items=2

Alina [70]

Answer:

x ≥ 5

y ≥ 10

3x + 2.3y ≥ 60

Step-by-step explanation:

Lets the number of men's shoes he sells be x and women's shoes be y.

For each men's shoes , he gets a commission of $3 and for each women's shoe, he gets a commission of $2.30 .

He needs to sell atleast 10 women's shoes and 5 men's shoes.

Also he needs to make atleast $60 per week.

x ≥ 5

y ≥ 10

3x + 2.3y ≥ 60

These are are the 3 required inequalities.

Now we will see an example.

If he sells 20 womens shoes and 10 mens shoes , he will meet the requirements.

He will make a total profit = $2.3\times 20 + 3\times 10$ =$76

kondor19780726 [428]

Answer: The number of different combinations of 2 vegetables are possible = 15 .

Step-by-step explanation:

In Mathematics , the number of combinations of selecting r values out of n values = $^nC_r=\dfrac{n!}{r!(n-r)!}$

Given : Number of available vegetables = 6

Then, the number of different combinations of 2 vegetables are possible will be :

$^6C_2=\dfrac{6!}{2!(6-2)!}=\dfrac{6\times5\times4!}{2\times4!}=15$

Hence , the number of different combinations of 2 vegetables are possible = 15 .

Sindrei [870]

Both servings of pancakes cost $8.50

One serving of pancakes cost $4.35

Equation: 1.15 (2x + 1.50) = 11.50

2.3x + 1.725 + 11.50

2.3x = 9.725

x = 4.25 for one serving of pancakes

2x = 8.50 for both servings of pancakes
