Claire is working two summer jobs, making $7 per hour washing cars and making $15 per hour clearing tables. In a given week, she can work at most 9 total hours and must earn a minimum of $90. If xx represents the number of hours washing cars and yy represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.
Answers
Claire must work 4 hours cleaning tables and 5 hours washing cars to earn more than $ 90.
Since Claire is working two summer jobs, making $ 7 per hour washing cars and making $ 15 per hour clearing tables, and in a given week, she can work at most 9 total hours and must earn a minimum of $ 90, to determine one possible solution the following calculation must be performed:
15 x 9 = 135 135 - 90 = 45 45/7 = 6.42 6 x 7 + 3 x 15 = 42 + 45 = 87 5 x 7 + 4 x 15 = 35 + 60 = 95
Therefore, at a minimum, Claire must work 4 hours cleaning tables and 5 hours washing cars to earn more than $ 90.

What is the product of ( 7 − 3 i ) × ( 4 + i ) ?
Answers
Answer: 31-5i
Step-by-step explanation:
28+7i-12i-3i^2
28-5i+3
31-5i
Answer:
31 - 5i
Step-by-step explanation:
(7 - 3i) * (4 + i)
Step 1: Multiply complex numbers 7 − 3i and 4 + i like you multiply binomials.
7 * 4 + 7i - 3i * 4 - 3i²
Step 2: By definition, i² is -1.
7 * 4 + 7i - 3i * 4 - 3 ( - 1)
Step 3: Do the multiplications.
28 + 7i - 12i + 3
Step 4: Combine the real & imaginary parts.
28 + 3 + (7 - 12)i
Step 5: Do the additions.
31 - 5i
The product of (7 - 3i) and 4 + i is 31 - 5i.
graph 3x+6y=18 In the box below, enter the y value when x = 2.
Answers
Answer:
y = 2
Step-by-step explanation:
3x + 6y = 18
3(2) + 6y = 18
6 + 6y = 18
Since 18 - 6 = 12, y will equal 2.
6 + 6(2) = 18
6 + 12 = 18
The coordinates to graph the equation would be (2, 2).

Answer:
x = 36 degrees
y = 48 degrees
Step-by-step explanation:
The two given triangles are congruent
Hence, we can say that the interior angles are equal
We shall use the angle markings on each of the triangles
Using the markings, we can see that y is 48 degrees
Now, let us find the last angle measure of the first triangle
Mathematically, the sum of angles in a triangle is 180
Thus;
108 + 48 + A = 180
A = 180 - 48 - 108
A = 180 - 156 = 24
Now, the measure 2x-y is equal to this;
Hence;
2x -y = 24
2x = 24 + y
we have that y = 48
2x = 24 + 48
2x = 72
x = 72/2
x = 36 degrees

SA = [ ? 17 cm?
Answers
Answer:
SA = 200π cm²
Step-by-step explanation:
The slant height l is the hypotenuse of the right triangle inside the cone
The triangle is an 8- 15- 17 ( Pythagorean triple ) with l = 17
Then
SA = πrl + πr²
=(π × 8 × 17) + (π × 8²)
= 136π + 64π
= 200π cm²
Answer:
in the right angle triangle,
p=15cm
b=8cm
[tex]h = \sqrt{15 {}^{2} + 8 {}^{2} } \\ = \sqrt{125 + 64} \\ = \sqrt{289} \\ = 17cm \\ sa = \pi \: rl + b \\ = \pi \: 8 \times 17 + \pi \: r {}^{2} \\ = 136\pi + 64\pi \\ = 200\pi[/tex]
