You sometimes need to rewrite a factor because the lead number is not between 1 and 10 as it needs to be in scientific notation. For instance, if we had lead numbers of 2 and 5, as we do in the following problem.
2x10^3 * 5x10^9
Then we get the answer of 10x10^12. We need to adjust this by moving the decimal place and increasing the exponent by 1. The correct answer would be 1x10^13 instead.
A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
Tow ratios that have the same value when simplified.
Hope this helps!!;)
Answer:
3.1, 3.2, 3.3
Step-by-step explanation:
There are infinite options but a rational number is a fraction, decimal, or repeating decimal.
3
is an example of a fraction between 3 and 4
3.2 is an example of a decimal between 3 and 4
3.3333333... is an example of a repeating decimal between 3 and 4
Answer:
98
Step-by-step explanation:
the time taken is directly proportional and so we multiply 7 by 56 and the divide the answer by 4 to get 98
