3/4 of the same number 0.75
Answer:
It is closer to 1/2.
Step-by-step explanation:
First of all, 10/9 is the same thing as 1 1/9.
Draw a number line:
1/2 1
--|------|------|------|-----|---|---|------|------|------|-----|-----
0/9 1/9 2/9 3/9 4/9 5/9 6/9 7/9 8/9 9/9
Halfway between 4/9 and 5/9 is the same as 1/2 and 9/9 is the same as 1.
You can see that 1/9 is way closer to 1/2 than 1.
So, 10/9 is closer to 1/2.
(There are other ways to solve this, but this way is easiest for me!)
Answer:
71 degrees
Step-by-step explanation:
Sum of three angles of triangle=180
Let's find the third angle
73+36=109
180-109=71
Vertical angles are congruent so x= angle 3
So x is 71 degrees
A=1/10, b=1/12, c=1/15 (these are the rates for each worker...)
1.)
2(1/10)+4(1/12)+t/15=1
1/5+1/3+t/15=1
(3+5+t)/15=1
3+5+t=15
8+t=15
t=7
So it would take c 7 hours to finish the job.
2.)
1/40-1/60
(3-2)/120
1/120
The drain rate is 1/60. So you will need to find t when the tank is empty, while starting at 2/3 capacity...
2/3-t/60=0
(40-t)/60=0
40-t=0
t=40
It would take 40 minutes to empty the tank when it is 2/3 full.
