0.04 ones, I think.
since you're doing place value.
Let Paul's house be at the origin of a coordinate grid. then Mary lives at (-6,-9) and Benjamin lives at (7,3). using the distance formula for these two points gives us d=√(-6-7)² + (-9-3)².
d=√169+144 or√313 miles, or about 17.69 miles.
Answer:
The time of a commercial airplane is 280 minutes
Step-by-step explanation:
Let
x -----> the speed of a commercial airplane
y ----> the speed of a jet plane
t -----> the time that a jet airplane takes from Vancouver to Regina
we know that
The speed is equal to divide the distance by the time
y=2x ----> equation A
<u><em>The speed of a commercial airplane is equal to</em></u>
x=1,730/(t+140) ----> equation B
<u><em>The speed of a jet airplane is equal to</em></u>
y=1,730/t -----> equation C
substitute equation B and equation C in equation A
1,730/t=2(1,730/(t+140))
Solve for t
1/t=(2/(t+140))
t+140=2t
2t-t=140
t=140 minutes
therefore
The time of a commercial airplane is
t+140=140+140=280 minutes
Answer:
B) 2
Step-by-step explanation:
