<span>Chaneece chooses x as the larger number and uses the inequalities y ≤ 40 – x and y ≤ x – 20 to determine the possible solutions.
</span>y ≤ 40 – x, if x must be between 0 and 10, y must be between 20 and 40 <span>it is true
proof
</span><span>for x=0 and y=10, y ≤ 40 – x equivalent to 10<40-0=40 it is true
</span>x=10, y=30, <span>y ≤ 40 – x equivalent to 30=40-10=30 it is true
the answer is </span><span>A) Yes, Chaneece found the correct solution. </span>
The missing length in the right triangle as given in the task content is; 156.
<h3>What is the missing length indicated?</h3>
It follows from the complete question that the triangle given is a right triangle and the missing length (longest side) can be evaluated by means of the Pythagoras theorem as follows;
x² = 144² + 60²
x² = 20736 + 3600
x² = 24,336
x = √24336
x = 156.
Remarks: The complete question involves a right triangle and the missing length is the longest side.

Answer:
90.91% probability that a car needs an oil change given that it has a certain factory defect
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this problem, we have that:
Event A: having a factory defect.
Event B: needing an oil change.
The probability that a car has a certain factory defect is 825.
So 
The probability that a car has a certain factory defect and needs an oil change is 750.
So 
What is the probability that a car needs an oil change given that it has a certain factory defect
90.91% probability that a car needs an oil change given that it has a certain factory defect
Lets do this:-
A. 7 Sandwiches
18 - 7 = 11
7 × $7.75 = $54.25
7 sandwiches cost $54.25.
11 × $4.50 = $49.50
11 soups costs $49.50
49.50 + 54.25 = 103.75
A is not d answer cuz d total of d lunches came to $113.50.
B. 8 sandwiches
18 - 8 = 10
8 × $7.75 = $62
8 sandwiches cost $62.
10 × $4.50 = 45
8 soups costs $45
62 + 45 = 107
B is not d answer cuz d total of d lunches came to $113.50.
C. 9 Sandwiches.
18 - 9 = 9
9 × $7.75 = 69.75
9 sandwiches cost $69.
9 × $4.50 = 40.50
9 soups costs $40.50
69 + 40.50 = 109.5
C is not d answer cuz d total of d lunches came to $113.50.
D. 10 Sandwiches
18 - 10 = 8
10 × $7.75 = $77.75
10 sandwiches cost $77.75.
8 × $4.50 = $36
8 soups costs $36.
77.75 + 36 = <span>113.75
</span>D is not d answer cuz d total of d lunches came to $113.50.
So, based on your answer choices there is no correct choice. <span />
