Answer:
Look at the number to the right of the full cents, if the number is five or more, increase the cents by 1. If the number is four or less, keep the cents the same. For example: Round $143.864. Look at the last digit, that is 4, since 4 is less than 5 so keep cents the same.
Step-by-step explanation:
Step-by-step explanation:11/8 is 12.5 goes into one hundred 8 times so 12 x 11 is 137.5so then turn decimals to a percent 1.405 is 140.5 1.45 is 145 so the it is 137.5 140.5,145

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is one leg
- b is another leg
- c is hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
a = 19
b = <em>x</em>
c = 21
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: 19² + x² = 21²
- Isolate <em>x</em> term: x² = 21² - 19²
- Exponents: x² = 441 - 361
- Subtract: x² = 80
- Isolate <em>x</em>: x = √80
- Simplify: x = 4√5
Answer:
3. 8 and 9
4. root 50 and root 144 for they are able to be multiplied to get a whole number/integer
5. 36 feet for the area is calculated be side x side all sides are equal so a number that has a whole root is the number so 36
6. 6 as would be one of the sides of the square rug
Hope this helps. Pls give 5 star, thanks, and brainliest.
