4 because 20,28, and 44 all can be divided bye 2 which comes out to be 10, 14 , and 22 they can also be divided by 2 which is 5,7, and 11 then your tow numbers that u divided was 2 and 2 so u multiply them and get 4!!! Lol
Each notebook would be 68 cents because if you divide 15.85 into 3 you will get 2 cents then you add 1.23 then subtract .75
Answer: option B is the correct answer
Step-by-step explanation:
On her math test, Heidi correctly
answered 35 of the 40 questions. This means the total number of questions in the math test is 40. If she was able to answer 35 correctly, that means the number of questions that she failed is total number of questions - the number of questions that she answered correctly. This becomes 40-35 = 5
This means that she failed 5 questions.
To find the percentage of questions that Heidi answered correctly, we will divide the number of questions that Heidi answered correctly by the total number of questions and multiply by 100%. It becomes
35/40 × 100 = 0.875 × 100
= 87.5%
Heidi answered 87.5% of the total questions correctly

Volume of a Cylinder Formula: V = πr²h
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
<em>V</em> = 81 cm³
<em>r</em> = 3 cm
<u>Step 2: Solve for </u><em><u>h</u></em>
- Substitute in variables [Volume of a Cylinder Formula]: 81 cm³ = (3.14)(3 cm)²h
- Evaluate exponents: 81 cm³ = (3.14)(9 cm²)h
- Multiply: 81 cm³ = (28.2743 cm²)h
- [Division Property of Equality] Divide 28.2743 cm² on both sides: 2.86479 cm = h
- Rewrite: h = 2.86479 cm
