Answer:
50
Step-by-step explanation:
v = the original speed of the cruise
d = 225 km the distance passed
t = d/v = 225/v the total time of the travel
v*1.5 + (v + 10)(d/v - 1.5 - 0.5) = d (using the formula distance = speed*time)
1.5v + (v + 10)(225/v - 2) = 225

Answer:
x≥26667
Step-by-step explanation:
let x= her sales
so the money she gets from her sales is .03x
if we wants at least 2900 we can write
2100+.03x≥2900
Solve for x
.03x≥800
x≥26666.6667
round up (because you can make a fraction of a sale) to get
x≥26667
Step-by-step explanation:
5x - 2y = 10
-5x -5x
----------------------
-2y = 10 - 5x
/-2 /-2
--------------------
y = -5 + 2.5x
Answer:
2466.08
Step-by-step explanation:
in 2466.075 the hundreth value is the 7. Since 5 makes the number go up when rounding, it is 2466.08
1, 1, 1, 1, 1
Any 5 values that are the same will have 0 std dev.
