6 times 10^4 is your answer hope i helped
Answer:
c 2
Step-by-step explanation:
h/3 + h/6 =1
Multiply both sides by 6 to eliminate the fractions
6(h/3+h/6) = 1*6
2h +h =6
Combine like terms
3h = 6
Divide by 3
3h/3 = 6/3
h =2
2 hours
Answer:
34. E 2 1/2
36. C 6cm
Step-by-step explanation:
34. ABC's triangle has 4, as it is equivalent to ADE's triangle's 10. I added 4 and 6 because the whole triangle shown is ADE. Then I did 10/4.
36. The reasoning is that on the other side, there is 9cm and 6cm which is equivalent to AB and 4cm
It goes like: 9/6 = AB/4
9 times 4 equals 36, and 36 divided by 6 is 6. Therefore the answer is 6cm.
Answer: Time it took her to get to the school is 0.6 hours
The distance of the school from their home is 27 miles
Step-by-step explanation:
Mrs Dang drove her daughter to school at the average speed of 45 miles per hour.
Let x miles = distance from the school to their home.
Distance = speed × time
Time = distance / speed
Time used in going to school will be
x/45
She returned home by the same route. This means that distance back home is also x miles.
She returned at an average speed of 30 miles per hour.
Time used in returning home from school will be x/30
x/45
If the trip took one half hour, then the time spent in going to school and the time spent in returning is 1 1/2 hours = 1.5 hours. Therefore
x/30 + x/45 = 1.5
(15x + 10x) /450 = 1.5
15x + 10x = 450 × 1.5 = 675
25x = 675
x = 675/25 = 27
Time it took her to get to the school will be x/45
= 27/45 = 0.6 hours
