A company is planning to make a new kind of radio. The cost to produce x radios is C(x) = 80,000 + 10x. Meanwhile, the revenue earned by selling x radios is given by R(x) = 18x. If R < C, the company loses money. At what level of production does this happen?

Answers

Answer 1
Answer: C(x) = 80,000 + 10x\ \ \ \wedge\ \ \ R(x) = 18x\n\nR < C\ \ \ \Leftrightarrow\ \ \ \ 18x<80,000+10x\n \n8x<80,000\ /:8\n \nx<10,000\n \nAns.\ The\ company\ loses\ money\ at\ level\ of\ production\ 10,000\ radios.

Help i dont understand this.

1 * 1 = 1
11 * 11 = 121
111 * 111 = 12321
1111 * 1111 = 1234321
11111 * 11111 = 123454321
111111 * 111111 = 12345654321

the pattern is that with each '1' added, there is another consecutive number added. if there are 3 ones, it I'll go up to 3 and then back down to 1 (111*111=12321)
it is the same like that for every one.

In order to join an online learning community, there is there is a $20 startup fee and $5 monthly fee. Write an equation in slope-intercept form that model this situation

Answers

Answer:

y = 5x + 20

Step-by-step explanation:

Answer:

Y=5x+20

Because 20 is a fee that is in constant value and shouldn't be correlated with the amount of months using the subscription. 5 is the amount charged every month you keep the subscription. Y is outcome of cost, and x is the amount of months.

What is 149,597,870 in scientific notation

Answers

Answer:

1.4959787 × 10^8

Step-by-step explanation:

Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10^b.

Follow the steps below to see how 149,597,870 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 149,597,870

New Number: 1.49597870

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 4 9 5 9 7 8 7 0

Decimal Count: 1 2 3 4 5 6 7 8

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10^b

a = 1.4959787 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

1.4959787 x 10^8

Step 4

Check your work:

10^8 = 100,000,000 x 1.4959787 = 149,597,870

Hope this helped.

A number n plus 7 is less than or equal to 9

Answers

Final answer:

The subject of this question is Mathematics. The inequality n + 7 ≤ 9 can be solved by subtracting 7 from both sides. The solution is n ≤ 2.

Explanation:

The subject of this question is Mathematics. The question involves solving an inequality involving a number, n, that is added to 7 and is less than or equal to 9. To find the possible values of n, we can subtract 7 from both sides of the inequality:



n + 7 ≤ 9

n ≤ 9 - 7

n ≤ 2

So, the values of n that satisfy the inequality are any number less than or equal to 2.

Suppose your gasoline tank holds 18 gallons of fuel. Your tank is currently 20% full. How many gallons of fuel do you need to add to fill the tank?

Answers

I believe the answer is 14.4 gallons of fuel.
To get the answer, I did x over 18 = 20% of 100. You cross-multiply to get 100x = 360. Divide each side by 100 to get x = 3.6. Subtract that from 18 gallons to get your answer.
