Answer:
- It has taken Jake about 40 minutes to finish his Spanish homework.
Step-by-step explanation:
<u>We know that:</u>
- Homework = 4 hours = Spanish + Math + Science + History
- Spanish = 4 hours x 1/6
- Math = 4 hours x 1/4
- Science = 4 hours x 1/4
- History = 4 hours x 1/3
<u>Work:</u>
- Spanish = 4 hours x 1/6
- => 2 hours x 1/3
- => 2/3 hour
- => 2/3 x 60 minutes
- => 40 minutes
Hence, it has taken Jake about 40 minutes to finish his Spanish homework.
Answer:
3 times
Step-by-step explanation:
The total number of flips for each round is;
First flip + Second flip + Third flip = 3 flips
Average = [ext]Number of flips/Round[/ext]
Average = 3/1
Average = 3 times.
Check:
Suppose they all match at First and Second rounds,
Average = [ext]3 * 3 / 3[/ext]
Therefore, average = 9/3
Average = 3 times

Step-by-step explanation:
The price elasticity of demand will be calculated as:
q = 860 − 20p.
dq/do = -20
p = 38
Elasticity E(p) = (p/q) × dq/dp
= [38 /(860 - 20p)] × (20)
=38 × 20/(860 - 760)
= 7.6
Therefore, the price elasticity of demand when the price is $38 per orange is 7.6
Revenue = price × quantity
= p × q
= p × (860 − 20p)
= 860p - 20p²
Differentiating with respect to p
= 860 - 40p
40p = 860
p = 860/40
p = 21.50
Maximum Revenue = 860p - 20p²
= 860(21.50) - 20(21.50)²
= 18490 - 9245
= 9245
