Answer:
4.58 * 10 cms.
Step-by-step explanation:
The general form for scientific notation is
N * 10^n (where 1 ≤ N < 10 and n = an integer).
45.8 = 4.58 * 10^1 or 4.58 * 10.
19.4 divided by 2, to find the radius. Then square it, and then multiply it by pi. Which gives you A as the answer
5/7m - 2 - 6/7m = -13
5/7m - 6/7m - 2 = -13
-1/7m - 2 = -13
-1/7m = -11
-m/7 = -11
-m = -77
m = 77
Yes b is the right answer as the <is eating the thirty which means 15 is on the right to 30
Answer: D) Janelle can type 1/4 of a page in 2/3 of a minute
Step-by-step explanation:
Option A is wrong because based on the constraints, Janine would type less than 3/8 of a page in anything less than a minute. 8 > 3/8.
For that same reason, option B is wrong as well. 2 > 3/8.
1/2 > 3/8 so Option C is wrong for the same reason as the options above.
To test option D;
If Janine can type 3/8 of a page per minute, how much can she type in 2/3 minutes.
Assume the much she can type is x;
3/8 : 1
x : 2/3
1x = 3/8 * 2/3
x = 1/4
<em>Option D is therefore correct. </em>
