Answer:
The answer would be B: 8 ones, 4 tenths, and 5 hundredths.
Explanation:
First, you would have to use the equation: 1.57 + 6.88 = ?
Do the math, and 1.57 + 6.88 = 8.45
Now look at the answer choices. You can automatically get rid of every answer choice but B because none of them have an 8 in the ones place.
Answer:
226.19cm^2
Step-by-step explanation:
Total surface area of cylinder = 2πr(r + h).
Answer:
k = 11
Step-by-step explanation:
f(x)=3x+k,
We know the input is -1 so replace x with -1 and the output is 8 so replace f(x) with 9
8 = 3(-1) +k
8 = -3+k
Add 3 to each side
8+3 = -3+3+k
11= k
Answer:
In standard notation it is 0.0832
Step-by-step explanation:
Explanation:
Scientific notation is a way to abbreviate numbers that would be really LONG otherwise, either very large numbers or very small ones. It uses the exponent to tell you how many places to move the decimal point and in which direction, to get the number back in standard notation.
A negative exponent means the number is smaller than it looks. Here, it's smaller than
8.32
The exponent -2 means we have to move the decimal point two places to the LEFT.
Doing that gives us
0.0832
If the number in scientific notation were 8.32 x 102, you would move the decimal point two places to the RIGHT, giving you: 8,320, or 8,320.00 in standard notation.
Suppose you had to write a report about the national debt, which is in the trillions of dollars I think. Would you want to have to write all those zeros every time?
Instead, you could use scientific notation. Let's pretend the debt is 2 trillion dollars. You can write this as: 2.0× 10^12
since two trillion is a 2 followed by 12 zeros.
The answer is b when it's a negative exponent you have to put a one over the number
