Answer:
a=18
Step-by-step explanation:
-2a-10+a=-28
-1a-10=-28
+10 +10
-1a=-18
divide by -1
a=18
The pythagorean theorem equation is a^2 (a squared) + b^2 (b squared) = c^2 (c squared)
so a^2+b^2=c^2
The order is -1.4, -3/5, 1/4, 0.9, and 9/2. So
D is the correct answer
Answer:
Samuel slept for 1/4 of the distance.
Step-by-step explanation:
The information provided are:
- Samuel fell asleep halfway home.
- He didn't wake up until he still had half as far to go as he had already
- gone while asleep.
Consider that the total distance covered was 1.
Then from the first point we know that Samuel fell asleep after covering a distance of 1/2.
It is provided that he woke up only after covering half of the remaining distance.
That is, he slept for 1/4 of the remaining distance.
Thus, Samuel was asleep for 1/4th of the entire trip home.
10/12 in simplest form is 5/6.
Equivalent ratios would be 15/18, 20/24, and 25/30.
The rest is easy, give it a try.
