40 x 30 =

Answers

Answer 1

Answer:

Answer:

50 x 30

Step-by-step explanation:

Garcia company is a perfectly competitive firm. the market price of its output is $10. the firm is currently producing 100 units of output. at this level of output, the firmâ€™s average total cost is $8 per unit, its average variable cost is $6 per unit, and its marginal cost is $10 per unit. what is the firmâ€™s profit?

Answers

Answer: $200.
Any firm (regardless of market structure) will maximize profit by producing and selling the quantity at which marginal revenue is equal to marginal cost.In the special case of a perfectly competitive firm,marginal revenue is equal to price.

How do you solve this? 18 " n=21

Answers

$18 ^(n) =21$

$log(18) ^(n)=log(21)$

$n*log(18)=log(21)$

$n= (log(21))/(log(18))$

$n=1.053$

A coffee pot makes about 60 ounces of coffee. each of your coffee mugs can hold one cup of liquid. how many mugs can you fill?

Answers

The conversion factor between cup and ounces is that one customary cup contains 8 ounces. The number of mugs (m) that can be filled is the ratio between the available amount of coffee (c) and the volume (v) that the mug can hold.
m = c / v
m = (60 ounces) / (8 ounces / mug) = 7.5 mugs

Thus, you can fill only 7 cups and the 8th cup is only half full.

What is 12 divided by 6/7

Answers

What is the easiest way to divide whole numbers to fractions?
Just follow these two easy steps:
1. Multiply the whole number to the denominator of the fraction. In other words, the bottom number of the fraction will be multiplied to the whole number, like this:

12 ÷ 6/7 = n
6
7 x 12
You will have 6/ 84.
2. Simplify.
6 = 1, 2, 3, 6
84= 1, 2, 3, 4, 6, 7, 12, 14, 21, 42, 84

the GCF is 6. divide both numbers by 6, so the answer will be 1/14.

You can also get the reciprocal and proceed to multiplication , like this: (12/1 is the fractional form or the whole number 12.)
1/12 x 6/7=n
that makes 6/84 or 1/14.

12 / (6/7) = x
x = 12 * 7/6
x = 14

Choose the number that is composite.

Answers

A composite number has more than two factors. (B) 21 is a composite number because the factors of 21 are 7 × 3.

name the subset(s) of real numbers to which the number zero belongs. choose all that apply. a. irrational numbers b. integers c. whole numbers d. natural numbers

Answers

whole numbers is my opion

Final answer:

The subsets of real numbers to which the number zero belongs are integers, whole numbers, and natural numbers.

Explanation:

The subsets of real numbers to which the number zero belongs are b. integers, c. whole numbers, and d. natural numbers.

Integers: Zero is an integer because it can be represented as a whole number without a fractional or decimal part.
Whole Numbers: Zero is also a whole number because it is not a fraction or a decimal and can be represented as a positive or non-negative integer.
Natural Numbers: Finally, zero is considered a natural number by some mathematicians, but not all. It is important to note that the inclusion of zero in the set of natural numbers is a matter of convention.
