Answer:
Eudora ran for 30 minutes and use the jetpack for 1 hour and 30 minutes
Step-by-step explanation:
Lets call x the time she ran and y the time she was using a jetpack (in hours), we have
12x + 76y = 120
Since it took 2 hours we have that x+y = 2, hence y = 2-x. We can replace y in the equation above, obtaining
12x + 76(2-x) = 120
12x+ 152 - 76x = 120
12x-76x = 120-152
-64x = -32
x = -32/-64 = 1/2 (30 minutes)
As a result
y = 1-1/2 = 3/2 (1 hour, 30 minutes)
She ran for 30 minutes and use the jetpack for 1 hour and 30 minutes.
Answer:
0.00998 Inches
Step-by-step explanation:
Thickness of the light bulb filament = 0.01 Inch
Allowable error = 2%.
2% of 0.01 = 0.02 X 0.01 =0.0002 Inch
Therefore, the allowable thickness of the bulb filament
We can then calculate the least allowable thickness of the filament as:
The least allowable thickness of the filament is 0.00998 Inches.
Answer:
C for the graph:
Domain:{-3,-1,0,3}
Range:{-1,0,1,2,3}
A for the table:
Domain:{-2,0,2,4}
Range:{-3,-1,0}
Step-by-step explanation:
For the graph:
The Domain is moving across the graph horizontally, the Range is moving up the graph vertically.
It has to be C because when moving across it starts with -3 and ends with 3, and no other answer choice says that. Also when moving up, it starts with -1 and ends with 3, and no other choice but C does that.
Now for the table:
The range is the y values and the domain is the x values.
A is the only choice where the y values match the range and the x values match the domain.
Hope this helps
