Answer:803.84
Step-by-step explanation:
3.14 x (16^2) = 803.84.
16^2 is 256 so multiply that by 3.14
Answer:
450
Step-by-step explanation:
We know that Cole did jump rope for 7 1/2 minutes.
In one minute there are 60 seconds. So we know that for each minute there is a 60 in it.
So, 7 x 60 = 420 then a half minute is thirty seconds (we know this because half of sixty is thirty.)
So we simply add 30 to 420 getting 450.
Answer:
The first number should be a number between 1 and 10 (see explanation)
Step-by-step explanation:
For a number to be in scientific notation, a number between 1 and 10 has to be multiplied by a power of 10.
36.5 is not between 1 and 10, alternatively, you can rearrange it:
3.65 x 10^7 <----This would be the correct scientific notation
If Tim had $20 to spend on 6 pens, and after buying them he had $8 left, that means that he spent 20 - 8 = $12 dollars on those 6 pens.
This means that to calculate the price of one pen, you just need to divide the money he spent ($12) by the number of pens he bought (6), and that is 12/6 = 2. Each pen cost him <span>$2.</span>
25.8 - 5 = 20.8
20.8 divide by 2.5 = 8.32
so it should be 8
