Amanda plans to have 20 friends over to Watch NCAA Basketball on Saturday. She plans to serve pizza, wings, soda, and brownies.

Each person eats 3 pieces of pizza, 16 ounces of soda, and 1 brownie. Each pizza has 10 slices. She buys 64 oz. bottles of soda. She bakes brownies in 8” X 12” pan and cuts them into 2” X 3” pieces.
How many pizzas does she need?
How many soda bottles does she need?
How many pans of brownies does she need?

If bottles of soda cost $1.69, pizzas cost $12.99, and brownie mix cost $2.39, write an expression to calculate the cost of Amanda’s NCAA tournament party.

<h2><u>In total, she will need $98.34 to pay all of the foods she plans to serve at the party.</u></h2>

All of the work:

<em>How to solve the amount of pizza she needs:</em>

20 x 3 = 60

60 divided by 10 = 6

<em>How to solve the amount of soda bottled needed:</em>

20 x 16 = 320

320 divided by 64 = 5

<em>How to solve the number of pans she needs:</em>

20(2 x 3) = 40 x 60

40 x 60 divided by 8 x 12 = 5

<h2>THE COST CAN BE FOUND BY MULTIPLYING THE NUMBER OF THE ITEM NEEDED AND THE PRICE FOR EACH OF THE ITEM.</h2>

<em>Number of pizza she needs:6 pizza, costs $77.94</em>

<em>Number of soda bottles she needs:5 bottles, costs $8.45</em>

<em>Number of pans she needs:5 pans, costs $11.95</em>

<em>Add 77.94, 8.45, and 11.95 and get 98.34</em>

Answer:

B) 12.5%

Step-by-step explanation:

1. Find amount spent on clothes in July

$2800 * 8% = j

<em>j = $224</em>

2. Find amount spent of clothes in August

$224 + $126 = a

<em>a = $350</em>

3. Find the amount's percentage of the total

$350/$2800 = x

x = 0.125 = 12.5%

I have three times as many cats as Alice but Bob has 7 less cats than me. In total we have 56 cats. How many cats do I have?
Nookie1986 [14]

The number of cats that you have is; 27 cats

<h3>How to calculate algebra word problems?</h3>

Let the number of cats alice has be x.

Since you have thrice the amount of cats that alice has, then you have 3x cats.

Bob has 7 less cats than you. Thus, bob has; 3x - 7

If they have a total of 56 cats, then;

x + 3x - 7 + 3x = 56

7x - 7 = 56

7x = 56 + 7

7x = 63

x = 63/7

x = 9

Thus, number of cats you have = 3x = 3 * 9 = 27 cats

10[4 times 10 divided by (6^2-4^2) +1]
Genrish500 [490]

Answer:

19

Step-by-step explanation:

10[4 times 10 divided by (6^2-4^2) +1]

First you would multiply 6 x 6 = 36

10[4 times 10 divided by (36-4^2) +1]

Second you would multiply 4 x 4 = 16

10[4 times 10 divided by (36-16) +1]

Third you would subtract 36 - 16 = 20

10[4 times 10 divided by 20 +1]

Fourth you would add 20 + 1 = 21

10[4 times 10 divided by 21]

Fifth you would multiply 4 x 10 = 40

10[40 divided by 21]

Sixth you would divide 40 divided by 21 = 1.90

10[1.90]

Seventh you would multiply 10 x 1.90 = 19

Your answer would be 19.

Hope this helps. I am sorry if you get this wrong.

How do you rationalize the numerator in this problem?
maw [93]

To solve this problem, you have to know these two special factorizations:

x^3-y^3=(x-y)(x^2+xy+y^2)\\ x^3+y^3=(x+y)(x^2-xy+y^2)

Knowing these tells us that if we want to rationalize the numerator. we want to use the top equation to our advantage. Let:

\sqrt[3]{x+h}=x\\ \sqrt[3]{x}=y

That tells us that we have:

\frac{x-y}{h}

So, since we have one part of the special factorization, we need to multiply the top and the bottom by the other part, so:

\frac{x-y}{h}*\frac{x^2+xy+y^2}{x^2+xy+y^2}=\frac{x^3-y^3}{h*(x^2+xy+y^2)}

So, we have:

\frac{x+h-h}{h(\sqrt[3]{(x+h)^2}+\sqrt[3]{(x+h)(x)}+\sqrt[3]{x^2})}=\\ \frac{x}{\sqrt[3]{(x+h)^2}+\sqrt[3]{(x+h)(x)}+\sqrt[3]{x^2}}

That is our rational expression with a rationalized numerator.

Also, you could just mutiply by:

\frac{1}{\sqrt[3]{x_h}-\sqrt[3]{x}} \text{ to get}\\ \frac{1}{h\sqrt[3]{x+h}-h\sqrt[3]{h}}

Either way, our expression is rationalized.
