24 yards of ribbon would cost 50.64.

<h3>Further Explanation</h3>

This problem can be solved using ratios and proportion. It can be solved using an equation with one variable.

STEP 1: Sort the given.

To solve, first we must sort the given in the problem:

cost of 3 yards of ribbon = 6.33

STEP 2: Represent unknown as variable.

If we let x be the cost of yard of ribbon, we can represent the given above using the equation below:

$\boxed {3x =6.33}$

STEP 3: Solve for the variable.

Then we solve for x to get the price per yard. To do this, we divide both sides of the equation by 3 to cancel the coefficient of x:

$3x = 6.33\\\frac{3x}{3} = \frac{6.33}{3}\\\boxed {x = 2.11}$

Therefore, the price of one yard of ribbon is 2.11.

Now that we know the price per yard, we can calculate the price of 24 yards:

$price \ of \ 24 \ yards \ = 24x\\price = 24 \times \ 2.11\\\boxed {price = 50.64}$

A rectangular piece of cardboard is 16y cm long and 23 cm wide. Four square pieces of cardboard whose sides are 6y cm each are c

Anna11 [10]

Answer:

Area of remaining cardboard is 224y^2 cm^2

a + b = 226

Step-by-step explanation:

The complete and correct question is;

A rectangular piece of cardboard is 16y cm long and 23y cm wide. Four square pieces of cardboard whose sides are 6y cm each are cut away from the corners. Find the area of the remaining cardboard. Express your answer in terms of y. If your answer is ay^b, then what is a+b?

Solution;

Mathematically, at any point in time

Area of the cardboard is length * width

Here, area of the total cardboard is 16y * 23y = 368y^2 cm^2

Area of the cuts;

= 4 * (6y)^2 = 4 * 36y^2 = 144y^2

The area of the remaining cardboard will be :

368y^2-144y^2

= 224y^2

Compare this with;

ay^b

a = 224, and b = 2

a + b = 224 + 2 = 226

Answer:

1) B. $12

2) B. Rich burns 1 more calorie per minute than Katie

3) C. Jeffery walks 5 meters per minute slower than Fumi.

Step-by-step explanation:

1) earnings / hours = salary

salary = 24/2 = 60/5 = 96/8 = 12

salary = $12

2) The question describes Rich's graph to have the function of "y=8x." The graph shown that represents Katie's number of burned calories has the function of "y=7x." From that we can conclude Rich burns one more calorie per minute. See attached file for graph.

3) The question describes Fumi's graph to have the function of "y=85x." In order to find the function of Jeffrey's graph, we must use the two points provided from the graph. The point (10, 800) tells us that the point (1,80) would also fall on the line. From that, we can determine Jeffery's function to be "y=80x." 80 is 5 less than 85, so Fumi walks 5 meters per minute faster than Jeffery.
