17. Michelle spent $32 on hot dogs and hamburgers. Hot dogs were $5 and hamburgers $6. If she bought a total of 6 items, how many of each kind did she buy?

### Answers

4 hotdogs and 2 hamburgers

I am not sure if this is the only answer but i used trial and error to work this out.

I first calculated 6x 4= 24, meaning 4 hamburger. But that one left me with $8 left which would not work as each hot dog is $5 each. So the answer i got was:

4 hot dogs at $5 equals $20. 2 hamburgers equals $12. so all together, 20 plus 12= $32.

the area of a rectangular ice skating is 900 square yards. If the length of the rink is 100 yards what is the width of the rink?

### Answers

Based on the information given, the width of the rectangle is 9 yards.

The area of a rectangle is gotten as:

= Length × Width

In this situation, the area of a rectangular ice skating is 900 square yards ans the length of the rink is 100 yards.

Therefore, the width of the rectangle will be:

= 900/100

= 9

Therefore, the width is 9 yards.

Learn more about area on:

brainly.com/question/3948796

The formula for the area of a rectangle is A=length×width. So 900 sq. yards= 100 yards × width. Divide 900 by 100 and you get the answer:)

A pair of in-line skates is on sale for $90 iF this price represents 9% discount form the original price,what is the original price to the nearest cent

### Answers

The required original cost of the in-line skates is given as $100.00.

Given that,

A pair of in-line skates are on sale for $90, this price represents a 9% discount from the original price, and the original price to the nearest cent is to be determined.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,

Let the original price of the in-line skates be x,

according to the question,

0.9 [x] = 90

x = 90 / 0.9

x = $100

Thus, The required original cost of the in-line skates is given as $100.00.

Learn more about percentages here:

brainly.com/question/13450942

#SPJ2

Let x = original price in dollars

x is the original price

9% of this original price is equal to 0.09x

subtract: x - 0.09x = 0.91x

The discount price is equal to 0.91x and it's equal to 90 dollars, so they must be the same value. Ie.

0.91x = 90

0.91x/0.91 = 90/0.91

x =98.9010989

x =98.90

So the original price is $98.90

A pair of in-line skates is on sale for $90 if this price represents a 9% discount on the original price what is the original person nearest cent

### Answers

1 + 0.09 = 1.09

90 * 1.09 = 98.1

The original price of the in-line skates was $98.1

The original price would be 1,000 dollars.

A recipe calls for 1/4 cup of flour. Carter does not have a quarter-cup measuring cup, though he has a measuring cup that holds an eighth of the cup. How can carter measure the flour he needs for his recipe.

### Answers

Answer:

Carter should measure two times the flour in the cup to obtain the quarter of cup he needs to the recipe.

Step-by-step explanation:

To solve this problem you should use a simple equation. As Carter has a cup that holds an eighth of the cup and he need to add a quarter cup to the recipe he needs to find a factor that multiplied by gives as result the he needs, that is:

1. Let´s name x the factor and we have the following equation:

2. Solving for x:

The result x=2 means that Carter should measure two times the flour in the cup to obtain the quarter of cup he needs to the recipe.

Carter can use the 1/8 measuring cup two times to get 2/8 because 2/8 is equivalent to 1/4.

The sum of 3 consecutive odd numbers is 51 what is the second number in the sequence

### Answers

Answer:

The second number in the sequence is 17.

Step-by-step explanation:

Let the three consecutive odd numbers be 2x-1,2x+1 and 2x+3

As per the question, the sum of the 2 odd numbers is 51.

So forming the relevant equation:

(2x-1) + (2x+1) + (2x+3) = 51

=> 6x + 3 = 51

=> 6x = 51-3 = 48

=> x = 48/6 = 8

Calculating the individual numbers:

- 2x-1 = 2*8 -1 = 16 - 1 = 15

- 2x+1 = 2*8+1 = 16 + 1 = 17

- 2x+3 = 2*8 +3 = 16 + 3 = 19

So the consecutive odd numbers are 15,17,19 and the second number in the sequence is 17.
