Answer: false

Step-by-step explanation:

Surface Area Formula Surface Area Meaning

SA=2B+Ph Find the area of each face. Add up all areas.

SA=B+12sP Find the area of each face. Add up all areas.

SA=2B+2πrh Find the area of the base, times 2, then add the areas to the areas of the rectangle, which is the circumference times the height.

Algebra 1 Please help! thank u sm

Answer:

1. Slyvia is wrong. You treat the numbers normally when dividing the left side, so 3.61/4.1 = .88. When dividing the exponents, you subtract the numerator from the denominator, so -11-7 = -18. So, you do have .88 * 10^-18, at first, but when you are working in scientific notation you want the decimal to be greater than so, which requires us to add an additional -1, to make it 8.8 instead of 0.88. This is because we want to move the decimal place left one more time. This results in our final answer being 8.8 * 10^-19, which is not Slyvia's answer.

2. Dylan's answer is correct. He subtracted the exponents correctly, then moved the decimal place over one place towards the left.

3. Ethan is wrong. He added the exponents, instead of subtracting. However, you cannot do this, because when you are dividing exponents, you must subtract.

Step-by-step explanation:

I have this acronym I learned called MADSPM, which has helped me a lot. I never learned it in Algebra, but I wish that they had taught it. Each letter corresponds with an exponent rule. If this makes sense, here is what it stands for:

When you multiply, you add.

When you divide, you subtract.

When there are parentheses, you multiply.

In this case, it was solely division. So, you just need to remember division = subtraction, when it comes to exponents.

Hopefully this helped. If you need me to explain it better, please let me know, and I will try. Thanks much & have a wonderful day!

Jake says adding 0 to an addendum does not change a sum. Is he correct

Nothing changes if you don't add anything. 

Example:

10+10=20
20+0=20
 
nothing changes.

Which method do you prefer to use to find sums- count by tens and ones, use compatible numbers, or use friendly numbers and adju
Usimov [2.4K]

I prefer to use compatible numbers because by using this method it is easier to make a sum mentally. This is true because compatible numbers are close in value to the actual numbers. For a better understanding, let's take an example:


Suppose you have two numbers, namely 640 and 40. These two numbers are compatible for division because:


64 ÷ 4 = 16


So, we have used mental arithmetic to solve a more complex problem.
