3) Every year a classroom of students holds a car wash to raise money to help fund a good cause in their community. This year the class wants to purchase Electric Blankets for their local Senior Citizens Center. Each blanket costs 52 dollars. Their teacher says every year the class raises between 2,000 and 2,500 dollars. Using that estimate, what inequality below BEST represents how many blankets (B) the class can expect to buy for the Center?
A) B>2000
B) 2000
C) B<2500
D) 38<=B<=48
4) Jimmy does yard work around his neighborhood. In a given week he works at least two days, but no more than five. And on the days he does work, he earns at least three dollars per day, but no more than seventeen dollars per day. Write an inequality that models how much money (M) Jimmy makes per week.
A) 5<=M<=22
B) 3<=M<=17
C) 6<=M<=85
D) 2<=M<=5
5) A school wants to put on a dance recital. Middle School dancers have short programs that run four minutes long. High School performers will dance longer with longer programs seven minutes in length. The entire program cannot have more than ten dances and the entire recital must be over in less than 90 minutes. What pair of inequalities BEST represents the number of short Middle School dances (M) and the number of longer High School dances (H) that can be performed given these limitations?
A) M+H>=10,4M+7H<90
B) M+H<=10,4M+7H<90
C) 4M+7H<=10,4M+7H<90
D) M+H<=10,M+H<90

Answer:
Step-by-step explanation:
total length = 6 + 6 + 6 = 18 cm
total breadth = 3 + 3 + 3 = 9 cm
perimeter = 2 ( l + b )
= 2 ( 18 + 9 )
= 2 × 27

The lines of symmetry for the graph of equation 4x² + y² = 9 are the x-axis and the y-axis.
To determine the lines of symmetry of the graph of equation 4x² + y² = 9, we need to analyze the form of the equation.
The given equation represents an ellipse, as it contains terms for both x² and y².
Comparing this with the given equation 4x² + y² = 9, we can rewrite it as:
(2x)²/3² + y²/3² = 1
By comparing the equations, we can deduce that a² = 3² and b² = 3². This means that the major axis has a length of 2a = 2(3) = 6 and the minor axis has a length of 2b = 2(3) = 6.
Since the ellipse is symmetric with respect to both the x-axis and the y-axis, there are two lines of symmetry.
