Answer:

A) 20.82 > 20.55

Step-by-step explanation:

Hopefully, your issue is with the symbols (< vs >) rather than actually determining which number is larger or smaller.

The wide-open end of the symbol (the left side, in the case of >) indicates the larger (more positive) number.

So, the meanings of the symbols are ...

> — "is greater than"

< — "is less than"

The only true statement of those listed is ...

20.82 is greater than 20.55, or 20.82 > 20.55 . . . . selection A

_____

When writing number comparisons, I like to use the < symbol, because it puts the numbers in number-line order. That is, the smaller (or more negative) number is on the left, just as it is on a number line.

You trade the places of the numbers when changing the symbol. For example, answer choice A could be rewritten as ...

20.55 < 20.82

You know that 20.55 is to the left of 20.82 on the number line, so you know this statement is true.

He pays $86.70 for the carpet. 8 time 10.2 equals 81.6.
10.2 divided by 2 equals 5.1. you will use 5.1 later.
81.6 + 5.1 = 86.7

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 8% vinegar, and the second brand co

Flura [38]

Let f and s denote the amounts of the first and second brands that the chef is going to use.

She wants to end up with 290 mL, so

f + s = 290

Each mL of the first brand contains 0.08 mL of vinegar, and each mL of the second contains 0.13 mL of vinegar. The final mixture should have a concentration of 12% vinegar, so that it contains 0.12 • 290 mL = 34.8 mL of vinegar, and

0.08f + 0.13s = 34.8

Solve for f and s :

f + s = 290 → s = 290 - f

0.08f + 0.13 (290 - f ) = 34.8

0.08f + 37.7 - 0.13f = 34.8

0.05f = 2.9

f = 58

s = 290 - 58

s = 232

The LA Dodgers hit the most homeruns in 2014. The number of homeruns accounted for 6% of the entire Major League Baseball home r

USPshnik [31]

To answer the question, we will need to find the 6% (the home runs of the LA Dodgers) of 583 (the entire Major League Baseball home run count).
To do that, first we are going to divide 6% by 100% to convert it to a fraction and get rid of the percentage signs :
$\frac{6}{100}$
Now we can multiply our fraction by the entire Major League Baseball home run count to get the home runs of the Dodgers:
$\frac{6}{100} (583)= \frac{(6)(583)}{100}= \frac{3498}{100}=34.98$

We can conclude that the LA Dodgers hit approximately 35 home runs.
