Mrs. Harper-Hudson plans to paint baskets for Art Club. The paint costs $14.50 and each basket cost $7.25. Write an equation for the total cost of the number of baskets made. Determine the cost of four baskets. (Indicate the units)

Answers

Answer:

14.50+7.25x = total

Step-by-step explanation:

or, 14.50+7.25b

b = # of baskets

therefore, 14.50+7.25(4) = 43.5

because 7.25 * 4 =29, so 14.50+29 = 43.5

Given f (x) = 1/x+11, find the average rate of change of f (x) on the interval [3, 3+h]. Your answer will be an expression involving h.

Answers

The average rate of change of the function in the interval is of:

[tex]A = -\frac{1}{14(14 + h)}[/tex]

What is the average rate of change?

The average rate of change of a function f(x) over an interval [a,b] is given by:

[tex]A = \frac{f(b) - f(a)}{b - a}[/tex]

In this problem:

The interval is [3, 3 + h], hence [tex]a = 3, b = 3 + h[/tex].[tex]f(3) = \frac{1}{3 + 11} = \frac{1}{14}[/tex][tex]f(3 + h) = \frac{1}{3 + h + 11} = \frac{1}{14 + h}[/tex]

Then:

[tex]f(b) - f(a) = \frac{1}{14 + h} - \frac{1}{14} = \frac{14 - 14 - h}{14(14 + h)} = -\frac{h}{14(14 + h)}[/tex]

[tex]A = \frac{-\frac{h}{14(14 + h)}}{3 + h - 3} = -\frac{-\frac{h}{14(14 + h)}}{h} = -\frac{1}{14(14 + h)}[/tex]

Answer:

3x-4y

Step-by-step explanation:

You need to simplify the equation. Because you can only add numbers with same variable, add 2x and x together to get 3x. Since 3x and -4y have different variables, they can't be added together, so this is the simplest form of the equation. JUST TO BE CLEAR, you won't be able to find the exact value of the variables unless you have more information. Therefore the only thing you can do is simplify.

The recommended storage temperature for a certain type of squash is 7°C to 15°C. Which inequality represents the possible storage temperatures F (in degrees Fahrenheit) of the squash.

Answers

Answer:

44.6 °F ≤ T ≤ 59 °F

Step-by-step explanation:

Firstly, we need to convert from celsius to Fahrenheit

That would be;

F =(9/5 * C) + 32

For 15

we have F = (9/5 * 15) + 32

F = 27 + 32 = 59 °F

for 7

we have F = (9/5 * 7) + 32

F = 12.6 + 32 = 44.6 °F

So we now write the inequality. That would be;

44.6 °F ≤ T ≤ 59 °F

Jada has $20 to spend on games and rides at a carnival. Games cost $1 each and rides cost $2 each.
Which equation represents the relationship between the number of games, x and the number of rides, y, that Jada could do if she spends all her money?​

Answers

Answer:

x + 2y = 20

Step-by-step explanation:

number of games = x

cost of 1 game = $1

cost of x games = $1*x = $x

number of rides = y

cost of 1 rides = $2

cost of y rides = $2*y = $2y

Total cost for x games and y rides = $x + $2y

given that he can spend all which he has

and he has $20

Then

Total cost for x games and y rides would be equal to total money had

thus

$x + $2y = $20

$ gets cancelled from both sides

thus

relationship between  x and y will be

x + 2y = 20  Answer

Peroxisomes use oxygen to break down fatty acids. In doing so, they use oxygen to remove hydrogens from fatty acid chains, yielding hydrogen peroxide (H2O2). Cells also routinely release potentially destructive molecules, such as superoxide (O2) in signaling, self-defense, or as a metabolic side product. Superoxide combines with hydrogen peroxide to make an even more destructive molecule called a hydroxyl radical. Therefore, the removal of these two reactants is a routine "housekeeping" chore within the cell. Which enzyme is used to prevent hydrogen peroxide accumulation in the peroxisome?
