Question 1: The area of the square is the product of the two sides. 24 times 24 is 576. Thus, the square is 576 square inches.

Question 2: (Answer is based off info received from comments)

The area of a circle is A = \pi r^2, where r is the radius. The diameter you have given me is 20 inches. The radius is half the diameter; thus, the radius is 10.

A = \pi r^2

A = \pi \times 10^2

A = 100\pi

They want us to approximate the area. \pi is approximately 3.14. If we use this value, we get 314 square inches.

Write an equation to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells cupcakes, c, for 1.50
Archy [21]

Answer:

\text{p}=\$1.20\text{c}-\$20

Step-by-step explanation:

GIVEN: Catherine sells cupcakes c for \$1.50 each, The ingredients for each cupcake cost her \$0.30, and the sum of all her other expenses is \$20/\text{month}.

TO FIND: Equation to represent Catherine's profit from selling cupcakes.

SOLUTION:

Cost of ingredients for each cupcake  =\$0.30

sum of all other expenses  =\$20/\text{month}

Selling price of each cupcake =\$1.50

Total cupcakes sold =\text{c}

Now,

As we know that \text{Net profit}=\text{Selling price}-\text{Cost price}-\text{Other expense}

putting values,

                      \text{p}=\$1.50\text{c}-\$0.30\text{c}-\$20

                      \text{p}=\$1.20\text{c}-\$20

Hence the equation  to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells is \text{p}=\$1.20\text{c}-\$20

Order: give Ceclor (cefaclor) 250 mg PO every 8 hours.
irinina [24]

Hello!

The answer is: 15 mL

Why?

From the statement we have that 250 mg need to be given every 8 hours, we can calculate how many mg will be given each day (24 hours):

\frac{24Hours}{8Hours} = 3

So,

3*250mg=750mg a day

We also know that there are 50 mg cefaclor every 1mL,

So, to know how many mL will be given with 750mg, we just need to divide it by 50

\frac{750}{50} = 15

Therefore,

15mL or 750 mg of cefaclor will be given each day.

Have a nice day!

2x+4y=6<br> 3x=12-6y<br> Solve by elimination
faltersainse [42]

Answer:

no solution

Step-by-step explanation:

2x + 4y = 6......reduces to x + 2y = 3

3x = 12 - 6y....reduces to x = 4 - 2y...rearranged is x + 2y = 4

so now we have :

x + 2y = 3

x + 2y = 4

ok....I dont have to go any farther to know that this has no solution because ur equations have the same slope and different y int, this means ur lines are parallel and have no solution because they never cross each others path.
