Answer:
5
Step-by-step explanation:
Okay, so adding negative numbers can get very tricky, but I think I can help
Since there are two negative signs next to each other, they both cancel out and become positive so instead you get
-2+7
And if you do this with a number line, if you start and negative 2 and keep going right 7 times, you get 5
I hope I helped! I know negative numbers can be really difficult, but once you get the hang of it I bet you'll be great!
In scientific notation, to obtain the original whole number. Move the decimal to the left if the exponent is negative and to the right if the exponent is positive.
So 1 inch = .00001578 miles
1225 / .00001578 = 77629911.28
To obtain the answer in scientific notation, move the decimal to the left until you have a single digit whole number and the rest of teh digits are to the right of the decimal. In this case 7 places. Now show it multiplied by 10 to an exponent equal to the number of places you moved the decimal. In this case the 7th exponent.
7.763 x 10^7
Answer:6.05cm
Step-by-step explanation:
Circumference=2×π×r
38=2×22/7×r

266=44r
r=266/44
r=6.05cm
