Answer:
b=6
Step-by-step explanation:
9/b=21/14
9/b=3/2
9=3/2b
9=3b/2
9×2=3b
18=3b
18/3=b
6=b
b=6
45 degrees. A right triangle is 90 degrees so 90-45=45.
Answer:
2400cm^3 I believe
Step-by-step explanation:
Let x be the number of hours she jogs, and y be the number of hours she bikes.
The total time would then be x + y = 5
The total distance (based on the given speeds) would be 6x + 12y = 50
Multiply the first equation by 6 to get 6x + 6y = 30
Subtract this from the second equation to get 6y = 20
y = 10/3 or 3 1/3
Substitute this value back into the first equation to get x = 5/3 or 1 2/3
Therefore, Yolanda will have to jog 1 2/3 hours and bike 3 1/3 hours.
In my opinion I think you would be able to make atleast 2 outfits
