The math club has 12 members. Each member pays monthly dues of $13.20. On the first day of the month, 8 members paid their dues. The remaining members paid their dues on the second day of the month. How much money was collected in dues on the second day of the month?

Answers

Answer: $52.80

Step-by-step explanation:

Number of members = 12

Monthly due per member = $13.20

Total amount expected = $13.20 × 12 = $158.40

On the first day of the month, 8 members paid their dues. Total amount paid will be:

= 8 × $13.20

= $105.60

The money that was collected in dues on the second day of the month will be:

= $158.40 - $105.60

= $52.80

If the blue troops hikes 2/3 if a mile every 1/2 hour, and the restrooms are 3/4 mile away from the cabin, how long will it take the blue troop to walk from the cabin to the restrooms?

Answers

Answer:

9/16 hour

Step-by-step explanation:

If the blue troops hikes 2/3 if a mile every 1/2 hour, and the restrooms are 3/4 mile away from the cabin,

Hence:

2/3 mile = 1/2 hour

3/4 mile = x hour

Cross Multiply

2/3 × x = 3/4 × 1/2

x = 3/4 × 1/2/ 2/3

x = 3/8 ÷ 2/3

x = 3/8 × 3/2

x = 9/16 hour

Therefore it will take the blue troop 9/16 hour to walk from the cabin to the restroom.

Your neighbor Philip buys a new alarm system that has two alarms (main and backup) with a 0.01 probability of a system failure. After reading the manual, he discovers that the second alarm has a 0.05 probability of failing. What is the probability of the first alarm failing?

Answers

Answer:

0.2

Step-by-step explanation:

Let P(A) = probability of first alarm failing and P(B) = probability of second alarm failing = 0.05. Since the events are independent, we have that the probability of both alarms failing or of system failure is P(A ∪ B) = P(A) × P(B).

Since the probability of both alarms failing or of system failure, P(A ∪ B) = 0.01, then the probability of the first alarm failing P(A) = P(A ∪ B)/P(B) = 0.01/0.05 = 0.2.

So, the probability of the first alarm failing P(A) = 0.2

A line graph is a graph made up of segments of straight lines that connect the depicted data points.

here, we have,

On a coordinate plane, the points (1, 2), (2, 4), (3, 6), (4, 8), and (5, 10) are plotted.

We have:

The line goes through points (1, 0.27) and (2, 0.54).

The x-axis represents the independent variable

The y-axis represents the dependent variable.

Thus, the statement first "The number of bananas is the independent variable, and the cost in dollars is the dependent variable" is correct.

Answers

x=6. explanation: first you would start off by using the distributive property which would be: 2(x-3)+4=10 —> 2x-6+4=10. next you would add like terms which would be -6 and 4: 2x-6+4=10 —> 2x-2=10. then you would subtract 2 from both sides: 2x-2=10 —> 2x=12. finally you would divide both sides by 2 and that would give you 6: 2x=12 —> x=6. to double check your answer you would replace x with 6 in the original equation. hopefully this helps.

2x + y=10
3x - 2y = 1

Answers

Solve
2x+y=10 for y:
2x+y=10

2x+y+−2x=10+−2x
(Add -2x to both sides)
y=−2x+10

Step: Substitute−
2x+10 for y in 3x−2y=1:
3x−2y=1
3x−2(−2x+10)=1
7x−20=1
(Simplify both sides of the equation)
7x−20+20=1+20
(Add 20 to both sides)
7x=21
7x=21
_ _
7 7
(Divide both sides by 7)
x=3

Step: Substitute
3 for x in y=−2x+10:
y=−2x+10
y=(-2)(3)+10
y=4
(Simplify both sides of the equation)

Step-by-step explanation:

2100 students were surveyed about whether they went to the Homecoming Dance and the Prom. 1470 students went to the Homecoming Dance. 570 students went to Prom only. 360 students went to both the Homecoming Dance and Prom. P (Went to Prom or None).

Answers

Answer and Step-by-step explanation: The problem can be solved by using a Venn Diagram.

A Venn Diagram shows the relation between a collection of different sets.

The figure below shows:  

1) Students who went only to the Homecoming = 1110

2) Students who went only to the Prom = 570

3) Students who went to both = 360

4) Students who went to none = 60

The question asks for the probability of students who went to Prom or None.

Probability of Prom = [tex]\frac{570}{2100}[/tex]

Probability of None = [tex]\frac{60}{2100}[/tex]

As it is asking for "OR", use the "or rule", i.e., add the probabilities:

P(Prom or None) = [tex]\frac{570}{2100}+\frac{60}{2100}[/tex]

P(Prom or None) = [tex]\frac{630}{2100}[/tex]

P(Prom of None) = 0.3

The probability of a student had went to Prom or none of them is 0.3 or 30%.

What is the radius of a hemisphere with a volume of 10470 in?, to the nearest tenth
of an inch?

Answers

Answer:

r ≈ 17.1 in

Step-by-step explanation:

Volume Of Hemisphere: 10,470

Volume Of Sphere: 20,940

Volume Of A Sphere: V = 4/3π(r)^3

20,940 = (4.1887902)r^3  [Evaluate 4/3π In Calc]

20940                  =                    (4.1887902)r^3

4.1887902                                     4.1887902

4999.0567625 = r^3

∛4999.0567625 = ∛r^3

17.0986841 = r
