Answer:24 , 4
Step-by-step explanation:
Given
There are 4 objects
(a)When the order is relevant
We use permutation to get the no of ways, that is
Choosing 3 objects out of 4
[tex]^4P_3=\dfrac{4!}{(4-3)!}=\dfrac{4!}{1!}\\^4P_3=24[/tex]
(b) When the order is not important, the same thing can be done in
[tex]^4C_3\ \text{ways}\\\\\Rightarrow \dfrac{4!}{1!3!}=4\ \text{ways}[/tex]

A unicycle wheel has a diameter of 30 inches. How many inches will the unicycle travel in 5 revolutions? Use π = 3.14 and round your answer to the nearest hundredth of an inch.
Answer:
471.3inches
Step-by-step explanation:
Given data
Diameter= 30in
Radius= D/2= 30/2= 15in
The circumference is the same as the distance covered in one revolution
C= 2πr
Hence the distance covered in 5 revolutions is
C= 2*5*πr
Substitute
C=10*3.142*15
C= 471.3inches

The americans with disabilities act sets a maximium angle for a wheelchair ramp entering a business at 4.76 degrees. Determine the horizontal distance needed to occomidate a ramp that goes up to a door.
Answer:
d = 48.03 feet
Step-by-step explanation:
Given that,
The maximum angle for a wheelchair ramp entering a business at 4.76 degrees.
We need to find the horizontal distance needed to accomidate a ramp that goes up to a door 4 feet of the ground.
We can solve it using trigonometry.
[tex]\tan\theta=\dfrac{h}{d}[/tex]
Where
h is height
d is the angle of elevation
[tex]d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{4}{\tan(4.76)}\\\\d=48.03\ ft[/tex]
So, the horizontal distance is equal to 48.03 feet.

A. 4*5*tD. t + 5 + 4Answer:
Solution :-Second option is correct because t is the breadth and 5 and 4 are length. So, Option B is correct 5t + 4t
On adding both we get 9t. Option C is correct
We may also take t as common and may be written as

In the diagram to the right, a right circular cone has a diameter of 8 inches and a height of 12 inches.What is the volume of the cone to the nearest cubic inch? A. 201 in3 B. 481 in3 C. 603 in3 D. 804 in3
Answer:
(A) 201
Step by step explanation :
Volume of a cone is approximately equal to [tex]\boldsymbol{201}[/tex] inches.
So, option A. is correct.
Volume of coneA cone is a three-dimensional geometric object with a smooth trans-ition from a flat base to the ap-ex or vertex.
Radius of a cone is half of the diameter.
Radius of a cone [tex](r)=\frac{8}{2}[/tex]

Height of a cone [tex](h)=12[/tex] inches
Volume of a cone [tex]=\frac{1}{3}\pi r^2 h[/tex]
[tex]=\frac{1}{3}(\frac{22}{7} ) (4)^2 (12)[/tex]
[tex]\approx 201[/tex] inches

Given that h varies inversely with respect to g, and that h= -24 when g= 3, write an
equation that describes the relationship between h and g. Then find h when g=-1,
Answer:
h = 72
Step-by-step explanation:
Given that h varies inversely with g then the equation relating them is
h = [tex]\frac{k}{g}[/tex] ← k is the constant of variation
To find k use the condition h = - 24 when g = 3 , then
- 24 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
- 72 = k
h = - [tex]\frac{72}{g}[/tex] ← equation of variation
When g = - 1 , then
h = - [tex]\frac{72}{-1}[/tex] = 72

For what values of x is g(x) > f(x)?
O A 0 < x < 2 and x > 4
OB. 2
C. X > 4
OD. X > 2
Answer:
Step-by-step explanation:
Given the functions f(x) = 2x^2 + 2 and g(x) = 2^x+1 + 2
If g(x) > f(x)
2^(x+1) + 2 > 2x^2 + 2

Gary goes to the grocery store to buy hot dogs and hamburgers for a cookout. He buys a total of 8 packages for a total of $28.52. A package of hot dogs costs $2.29 and a package of hamburgers costs $5.69.
Answer:
3 hamburger packs
5 hot dog packs
Step-by-step explanation:
The system of equations that corresponds to the situation is:
1. x + y = 8
2. 2.29x + 5.69y = 28.52
Let's use variables to represent the unknowns in the problem.
Let:
x = number of packages of hot dogs purchased
y = number of packages of hamburgers purchased
We are given the following information:
1. Gary buys a total of 8 packages: x + y = 8
2. The total cost of the packages is $28.52: 2.29x + 5.69y = 28.52
So, the system of equations that corresponds to the situation is:
1. x + y = 8
2. 2.29x + 5.69y = 28.52
