Answers

Answer 1

Answer: at 4:30 the temperature is 40 degrees, and this temperature is 8 degrees more than what is was at noon. so we subtract 8 from 40 to get 32 degrees at noon. then we subtract 5 from 32 to get the temperature at 7 am. The temperature at 7 am is 27 degrees

A grocery store only sells eggs by the dozen.There are 12 eggs in one dozen eggs.If there are 624 eggs in stock how many dozens of eggs are there

Answers

work:

624 divided by 12 equals 52

answer:

52 dozens

Final answer:

Given a stock of 624 eggs and knowing 1 dozen equals 12 eggs, there are 52 dozen eggs in the store.

Explanation:

The subject of this question pertains to Mathematics, specifically a real world application of division. In the given query, a grocery store only sells eggs by the dozen, meaning twelve eggs. The store has in stock, 624 eggs. The task is therefore to determine how many dozens make up this total number of eggs available.

To find the answer, we divide the total number of eggs by the number of eggs in one dozen. That is 624 (total number of eggs) divided by 12 (number of eggs in a dozen). This equals 52 dozens. Thus, the grocery store has 52 dozens of eggs in stock.

How many whole numbers have exactly 3 digits

Answers

The biggest one is 999.

If you started counting from 1 to 999, you would count to 99
before you get to the first 3-digit number.

So there are (999 - 99) = 900 of them.

999 because If you add one to 999 it's 1,000 and you'll go into the 4 digits

Mary was making $25,000 per year. Her boss gave her a $3,000 raise. What percent increase is that? PLZ HELP

Answers

The easiest way to find a percentage is to divide the two numbers. You're trying to find what percent 3,000 is of 25,000, so you divide 3,000 by 25,000 to find the decimal.
3000/25,000 = 0.12
If you move the decimal point to the right two places, you'll have your percentage. (Percent means "out of one hundred", and since the decimal point is now in what was the hundredths place, it is now a percentage instead of a decimal.)
12%
$3,000 is a 12% raise from $25,000.
