Answer:
His estimate is somewhat low.
Step-by-step explanation:
The total bill is $9.50 +3.50 = $13.00. The estimated tip is 15% of $10, so Jamal needs to add 15% of $3, or $0.45, to his estimate to leave a tip equal to 15% of the bill.
The tip Jamal has calculated is about 11.5% of the bill. (1.50/13.00 ≈ 0.1154)
The tip Jamal wants to leave is $1.95. (0.15·13.00 = 1.95)
<h3>
Answer: Bottom left corner (southwest corner)</h3>

The left endpoint is x = 4, but we don't include this endpoint because of the open hole. We use a parenthesis to indicate "don't include the endpoint"
The right endpoint is positive infinity. We always use a parenthesis with either infinity since we cannot reach infinity
The interval from 4 to infinity is written as
which is like saying 
Answer:
Step-by-step explanation:
<u>Solve the equation:</u>
- 3x² - 12 = 0
- x² - 4 = 0
- x² = 4
- x = √4
- x = 2 is the positive solution
Correct choice is B
Circle: 8m times 3.14 squared = 201
two circles: 201 times 2 = 402
entire figure including circles: 24 times 34 = 816
