Mrs. Ramiriz is making pies to sell at the local farmer’s market. It costs her $5 to make each pie, plus a one-time cost of $30 for baking supplies. She plans to sell the pies for $12 each. Which equation can be used to find the number of pies she needs to sell to break even?a.5x – 12x = 30
b.5x + 12x = 30
c.5x + 30 = 12x
d.12x + 30 = 5x

Answers

To answer the problem above, we must first define the word break even. Break even means there is no gain or loss, the difference between the capital amount and the sale amount is zero. In equation, let x be the number of pies. 5x + 30 = 12x, $5 times the number of pies plus $30 is equal to $12 times the number of pies sold. The answer is letter C.

Answer:

c.5x + 30 = 12x

Step-by-step explanation:

Given :Mrs. Ramiriz is making pies to sell at the local farmer’s market. It costs her $5 to make each pie, plus a one-time cost of $30 for baking supplies. She plans to sell the pies for $12 each.

To Find: Which equation can be used to find the number of pies she needs to sell to break even?

Solution:

Let no. of pies be x

It cost her $5 to make each pie

so, cost of making x pies = 5x

Since there is a one-time cost of $30 for baking supplies.

So, total cost for her is 5x+30

If she sells each pie for $12

Then cost of pies = 12x

Now equation can be used to find the number of pies she needs to sell to break even:

5x+30=12x

The triangle perimeter size does not change because all the components rotate and reflect together.

What is the solution of the system defined by y = -x + 5 and 5x + 2y = 14?Ax=1/3, y=11/7
Bx=4/3, y=11/3
Cx=5/11,y=0
Dx=4/3,y=1

Answers

y = -x + 5
5x + 2y = 14

5x + 2(-x+5) = 14
5x - 2x + 10 = 14
3x = 14 - 10
3x = 4
x = 4/3 or 1 1/3

y = -x + 5
y = -4/3 + 5
y = -4/3 + (5 * 3/3)
y = -4/3 + 15/3
y = -4+15 / 3 
y = 11/3 or 3 2/3

Correct answer is B. x = 4/3 ; y = 11/3

A certain microscope is able to magnify an object up to 100,000 times its original size. In scientific notation, 100,000 is _____.

Answers

Answer: In scientific notation, 100,000 is 1.0*10^5

Step-by-step explanation:

We know that the scientific notation is a technique to describe a very large or a very small number in the product of a decimal form of number [generally between 1 and 10] and powers of ten.

The given number = 100,000

Here the number of zeroes = 5

Then, in scientific notation, 100,000 =1.0*10^5
shift 5 decimal places to the left, so the exponent for base 10 is 5. Therefore, the number in scientific notation is: 
1.0 x 105
