Matt was babysitting for friend's parents Saturday morning and was paid $10 per
hour for 3 hours. Later that evening, he was babysitting for another couple that paid
him $20 per hour for 5 hours. What was Matt's average rate of pay per hour for the
day?
Answer:
Matt was paid an average of $10 per hour of babysitting for the day.
Step-by-step explanation:
He babysat in the morning for 3 hours being paid $10 per hour. He later babysat in the evening for 5 hours being paid $20 per hour. Since he was being paid two different amounts throughout the day, the average would be $10. He was being paid atleast $10 per hour for babysitting because even though he was being paid $20 in the evening, the lowest amount of money that he was paid, was $10 making that the average.

Answer:
k = 3.5
Step-by-step explanation:
Area of a rectangle = length × width
Area of the bigger triangle - Area of the smaller triangle = 35 cm²
Thus:
(2k + 6)(k) - (3)(k) = 35 cm²
2k² + 6k - 3k = 35
2k² + 3k - 35 = 0
Factorise
2k² + 10k - 7k - 35 = 0
2k(k + 5) -7(k + 5) = 0
(2k - 7)(k + 5) = 0
2k - 7 = 0
2k = 7
k = 3.5
Or
k + 5 = 0
k = -5
The value of k would be the positive number which is 3.5.

Answer:
25 = 50%
37.50 = 75%
75 = 150%
Step-by-step explanation:
We know that 50 is 100% so we can work with that.
We also know the percentages increase by 25% for every $12.5.
12.50 + 12.50 = 25
25 + 12.50 = 37.50
62.50 + 12.50 = 75
25 = 50%
37.50 = 75%
75 = 150%
