This is my last question I need help with.
Viktor [21]

Answer:

Option 1

Step-by-step explanation:

The formula of constant porpotionality is

y = kx

or

y =  \frac{k}{x}

where k is the constant of porpotionality.

This equation is direct variation so we will use

y = kx

The equation is in the form

y = 1.5x

1.5 is in k place so the constant of porpotionality is 1.5

In each box is a step in the process of solving a max/min problem like the one in Question 8. Number these steps in order (1-8)
Dmitriy789 [7]

Answer:

The steps are numbered below

Step-by-step explanation:

To solve a maximum/minimum problem, the steps are as follows.

1. Make a drawing.

2. Assign variables to quantities that change.

3. Identify and write down a formula for the quantity that is being optimized.

4. Identify the endpoints, that is, the domain of the function being optimized.

5. Identify the constraint equation.

6. Use the constraint equation to write a new formula for the quantity being optimized that is a function of one variable.

7. Find the derivative and then the critical points of the function being optimized.

8. Evaluate the y-values of the critical points and endpoints by plugging them into the function being optimized. The largest y- value is the global maximum, and the smallest y-value is the global minimum.

Jenna wants to build 8 birdhouses. She needs 2 3/5 square feet of plywood for each birdhouse. If the plywood costs $0.56 per squ
goldenfox [79]

Answer:

$11.76

Step-by-step explanation:

We first need to find the amount of plywood for all birdhouses.

2 3/5 * 8 = 104/5 or 20.8 or 20 4/5

Now we can solve the cost for all the birdhouses by multiplying the total amount of plywood needed by the price per square foot.

20.8 * 0.56 = $11.648 or estimated $11.65

Remember, the question might be different, so don't submit anything yet. If the people who sell the plywood only sell in integer numbers (meaning you can't buy 4/5 of a square foot of wood but can only by amounts with no fractions), then Jenna must buy 21 square feet of plywood and will have a little bit of wood left over. Now solve just like before.

21 * 0.56 = $11.76

Therefore the answer is $11.76 if she can only buy an integer amount of plywood or estimated $11.65. I think the best answer is 11.76.

Write an expression to find the total cost of buying b paperback books and m magazines if magazines cost $4.95 each and paperbac
xxTIMURxx [149]

Answer:

Total\ cost=7.95b+4.95m

Step-by-step explanation:

Paperback Books:

Number of books=b

Cost of 1 book=\$7.95

Cost\ of\ all\ paperback\ books=cost\ of\ 1\ book\times number\ of\ books\\\\Cost\ of\ all\ paperback\ book=7.95\times b=7.95b

Magazines:

Number of magazines=m

Cost of 1 magazine=\$4.95

Cost\ of\ all\ magazine=cost\ of\ 1\ magazine\times number\ of\ magazine\\\\Cost\ of\ all\ magazines=4.95\times m=4.95m

Total\ Cost=Cost\ of\ paperback\ books+Cost\ of\ magazine\\Total\ Cost=7.95b+4.95m
