Work out the value of x
Answers
Answer:
67.5°
Step-by-step explanation:
Given, 90° + x + 3x = 360°
4x = 360° - 90°
4x = 270°
x = 67.5°
Answer:
67.5
Step-by-step explanation:
[tex]3x + x + 90 = 360[/tex]
[tex]4x + 90 = 360[/tex]
[tex]4x = 360 - 90[/tex]
[tex]4x = 270[/tex]

A punter kicks a football into the air. The pathway of the football can be represented by the equation h=-16t^2+82t (where t= time in seconds and h= height in feet.) How long will it take the football to reach the ground.
Answers
You would use the equation
16x^2 + 82x = 0 saying that the ground is 0 height.
So as you know by PEMDAS exponents are first so you would do 5.125^2 which is 26.265625,
So you would do -16 x 26.265625 which is -420.25
So now you know the left side of the equation, and the right side is easy since it is just 82 x 5.125, which is 420.25
And -420.25 + 420.25 = 0!
The time required for the ball to reach the ground is 10.25 seconds
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The punter kicks the ball into the air
The equation to determine the pathway is h = -16t² + 82t
where t is the time taken in seconds to reach the height h
So ,
Time taken by the football to reach ground is calculated from the equation
At the ground , the height will be 0
So , h = 0
Substituting the value for h in the equation , we get
0 = -16t² + 82t
Adding 16t² on both sides , we get
16t² = 82t
Divide by t on both sides , we get
16t = 82
Divide by 4 on both sides , we get
4t = 41
Divide by 4 on both sides , we get
t = 10.25 seconds
Hence , the time taken by the football to reach the ground is 10.25 seconds

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

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

I'm more stuck on simplifying the bottom the top part is fine
Answers
Answer:
(x+5)/(2x+3)
Step-by-step explanation:
So we know the top part is difference of two squares. So thats (x+5)(x-5)
The bottom part
Firstly you do 2 times -15= -30
Now we need to find two numbers with a difference of 7 but multiply to give 30.
30
1 x 30
2 x 15
3 x 10
5 x 6
From here we can see 3-10=-7 and multiply to make -30
So we do 2x²-10x+3x-15
simplify this in two different parts: 2x²-10x and 3x-15
2x(x-5) and 3(x-5)
Therefore we get (2x+3)(x-5)
(x+5)(x-5)/(2x+3)(x-5)
x-5 is common so they cancel each other out leaving you with
(x+5)/(2x+3)

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.

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

Answers
Answer:
$25
Step-by-step explanation:
If 2 bags of sunflower seeds cost $5 dollars, and you need 10 bags, you can do 5 x 5, where one 5 represents the cost and the other 5 represent the packs needed, which is 5 x 2.
Thus 5 x 5 = 25, 10 bags of sunflower seeds will cost $25.

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

x=3

3 for x in y=−2x+10:

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%.
