b. The school spent $500 on calculators. How many did the school buy?

Answers

Answer:

A. 31.25x=$500

B. 16

Step-by-step explanation:

The amount paid for x calculators is 31.25x.

The number of calculators the school bought is 16.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Cost of each calculator = $31.25

Cost of x calculators.

= 31.25x

Now,

The total cost of the calculators = $500.

The number of calculators bought.

= 500/31.25

= 16

Thus,

The cost of x calculators is 31.25x.

The number of calculators bought is 16.

Arrange the following measurements in order from smallest to largest

4.1 liters, 0.7 liters and 2,000 millimeters

Answers

Answer:

first we change 2000mm into litres and I think 1000 mm is equals to 1 L then you look at the first digit and in the first number we have for as the first digit the second number 0 the third number two so in this case 0.7 l is the smallest then 2000mm then 4.1 letters

The measurements in order from smallest to largest is,

0.7 liters, 2,000 millimeters, 4.1 liters

Here,

Given measurements are, 4.1 liters, 0.7 liters and 2,000 millimeters

We have to arrange in order from smallest to largest.

What is Measurements?

The process of associating numbers with physical quantities and phenomena is called Measurements.

Now,

1 liters = 1,000 millimeters

Hence, 2,000 millimeters = 2,000/1,000 = 2 liters

So,

The measurements in order from smallest to largest is,

⇒ 0.7 liters, 2 liters, 4.1 liters

⇒ 0.7 liters, 2,000 millimeters, 4.1 liters

PLZ HELPYoung made several mistakes. He thought the third hieroglyph was part of the one for T, whereas it actually stood for the vowel O. The fourth hieroglyph, the lion, meant just L, the fifth meant M, and the last hieroglyph stood simply for S. In other words, the spelling in Egyptian was Ptolmis, not Ptolemaios.But Young got three out of the seven symbols right, which was a better score than any scholar before him had achieved.Young published his findings in an article written for the 1819 supplement to the Encyclopedia Britannica. He continued to work on the problem of the hieroglyphs in the years that followed, but made little headway in deciphering additional names and words. Why? Largely because he was working under a false assumption.Like countless other scholars over the centuries, Young still believed that most of the hieroglyphs must have a symbolic meaning. Only in special cases, such as foreign names, did he think that they were used to represent sounds.Because of this mistaken belief, Young put roadblocks in his own path. However, he had laid a solid groundwork for others in their attempts to decipher the hieroglyphs.
