C = 15n + 85....when C = 385

385 = 15n + 85
385 - 85 = 15n
300 = 15n
300/15 = n
20 = n <== 20 watches were made

Given that,

Alonzo is $120 in debt. He makes $15 per hour. He wants to have at least $75 left over after he has paid off his debt.

To find,

The inequality and the solution.

Solution,

Let he make $x per hour. Here, $120 is fixed. $15 is added per hour.

ATQ,

$120 + 15x\ge 75$

For atleast, we use $\ge$ .

Subtract 120 from both sides.

$120 + 15x-120\ge 75-120\\\\15x\ge -45\\\\x\ge -3$

So, the required answer is greater than -3.

Small Town USA has a population of 4•10 to the power of 4. Big town has a population of 2•10 to the power of 5. How many times l

Kryger [21]

Big town is 5.121 times larger than Small town.

Step-by-step explanation:

Step 1:

In order to determine how much larger Big town's population is to Small town's population is, we need to convert the exponentials into actual numbers.

Small town's population $= 4.10\times 10^{4} = 41,000.$

Big town's population $= 2.10\times 10^{5} = 210,000.$

Step 2:

In order to determine how much larger Big town's population is to Small town's population is, we divide Big town's population by Small town's population.

$\frac{210,000}{41,000} = 5.121.$

So Big town is 5.121 times larger than Small town.

Order these numbers from smallest to largest:

babymother [125]

Answer:

Order from Least to Greatest

24/15 < 1 7/10 < 1 15/18

Step-by-step explanation:

Using the given inputs:

1 7/10 1 15/18 24/15

Rewriting all inputs as fractions:

1 7/10 1 15/18 24/15

17/10 33/18 24/15

The least common denominator (LCD) is: 90.

Rewriting as equivalent fractions with the LCD:

1 7/10 1 15/18 24/15

153/90 165/90 144/90

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

24/15 1 7/10 1 15/18

144/90 < 153/90 < 165/90

Therefore, the sorted inputs in order from least to greatest is:

24/15 < 1 7/10 < 1 15/18 Thank you :)
