Answer:
Susie reaches the store first being ahead by 0.06 hours.
Step-by-step explanation:
20 miles going 45 miles/hour.
20 miles / (45 miles / hour) = 20 miles hours / 45 miles =
= 20 hours / 45 = 4/9 hours = 0.44 hours
25 miles going 50 miles/hour.
25 miles / (50 miles / hour) = 25 miles hours / 50 miles =
= 25 hours / 50 = 1/2 hours = 0.5 hours
So Susie needs less time (= arrives first).
the difference is 0.5 - 0.44 = 0.50-0.44 = 0.06 hours
as additional practice :
0.06 hours is 60 × 0.06 minutes.
60 × 0.06 = 60 × 6 / 100 = 360 / 100 = 3.6 minutes.
The first day of the month would be the first saturday.
The equation of parabola is
.
The canonical equation of parabola is
and this parabola has branches that go in positive direction of x-axis.
Since in your equation x is changed to y and y to x, then the <span>branches of the parabola go in positive y-axis direction, the vertex is placed at the origin.

∠SCD =150 and ∠BCD=174 (Given)
∠BCS + ∠SCD = ∠BCD (Segment Addition Postulate)
∠BCS + 150 = 174 (Substitution)
∠BCS = 24 (Subtraction Property of Equality)
Answer: 24
Answer:
4000 units
Step-by-step explanation:
In 2001 the total number of marketed units= 730,000
If this number represents 50% of what was marketed in 2004, then the total number of units marketed in 2004 was:
(100/50)× 730,000=1460000
To get the number for each of the 365 days in 2004 we divide the total for 2004 by 365
1460000/365= 4000 units
