Answer:
300 miles
Step-by-step explanation:
The distance equation is D = RT
Where
D is the distance
R is the rate
T is the time
<u>Mindy</u>
8 am to 1 pm = 5 hours
<u>Kelly</u>
8 am to 2 pm = 6 hours
Kelly's rate is 10 mph SLOWER than mindy, so if we let Mindy's rate be "m", so Kelly's rate will be " m - 10 "
Now using the distance equation, we can write:
Mindy >>> D = RT >>> D = 5m
Kelly >>> D = RT >>> D = 6(m-10) >>> D = 6m - 60
Since both the distances are equal, we can write:
5m = 6m - 60
m = 60
We want the distance, we know:
D = 5m
D = 5(60)
D = 300 miles
The distance is 300 miles
Answer:
30% of picking a red marble, it is likely to occur.
Step-by-step explanation:
50% of green and 20% of blue. The most logical is to add to 100%. 50+20=70, 100-70=30. Thats the 30% of red. Since red is 10% than blue, it is likely to get a red marble.
I'll help with a few.
3. -3x^3 - 9x^2 + 3x
Solve:
= (-3x)(x^2 + 3x + -1)
= (-3x)(x^2)+(-3x)(3x)+(-3x)(-1)
= -3x^3 - 9x^2 + 3x
7. (m - 2) (m + 11)
8. (t - 2) (5t + 9)
9. (5x + 3) (5x - 3)
10. (3t + 2)^2
Answer:
Step-by-step explanation:
