Answer:
She made $105.75 working as a waitress
She made $367.50 working as a maths tutor
Step-by-step explanation:
Linda worked a total of 30 hours last week and she worked 9 of these hours as a waitress.
Hence, the number of hours worked as a maths tutor =
30 - 9
= 21 hours
When she works as a waitress she receives $11.75 per hour
Hence, $11.75 × 9 hours
= $105.75
Hence, she made $105.75 working as a waitress
When she works as a math tutor she received $ 17.50 per hour.
$17.50 × 21 hours
$367.50
Hence, she made $367.50 working as a waitress
The expression that will give a value that is close to 4 is: (2 + 3 + 4 + 6)/4.
<h3>What is an Expression?</h3>
An expression, in mathematics, is a combination of operation signs and numbers, and may also include variables.
We are restricted to use only digits between 0 - 9 to write an expression that will be as close as possible to 4.
Using the digits, 2, 3, 4, and 6. We would have:
(2 + 3 + 4 + 6)/4
= 15/4
= 3.75
3.75 is close to 4. Therefore, the expression would be:
(2 + 3 + 4 + 6)/4.

Answer:
a) 30cm²
b) 8.75cm²
c) 30cm²
Step-by-step explanation:
a) Area of a triangle = 1/2 × base × perpendicular height
= 1/2 × 12 × 5
= 30cm²
b) Area of a triangle = 1/2 × base × perpendicular height
= 1/2 × 3.5 × 5
= 8.75cm²
c) Area of a triangle = 1/2 × base × perpendicular height
= 1/2 × 5 × 12
= 30cm²
A because if you simplify the inequality you get m<11 The only answer which has values under 11 is A
