Answer:
BF = 30
Step-by-step explanation:
Since B and F are midpoints then BF is parallel to CE and half it's size
BF = 0.5 × CE = 0.5 × 60 = 30
Since he must not exceed 8 hours driving in a day:
Let the distance of the picnic be = x km.
Therefore time for forward journey = x / 60
Return journey = x / 50
The total trip should not exceed 8 hours.
Therefore: x / 60 + x / 50 <= 8. LCM = 300
Taking LCM and multiplying on both sides:
5x + 6x <= 8(300)
11x <= 2400
x <= 2400/11
x <= 218.18
The picnic spot must be less than or equal to 218.18 km.
Answer:
7,4,15,6
Step-by-step explanation:
7,4,15,6
2 pounds for $10.99 means 1 pound for $5.495 => 5 pounds for $27.475
(1/2) ^2 = 1/2 * 1/2 = 1/4
1/4 < 1/2
