If carpet is 1.49 per square foot, how much will it cost for them to get new carpet for the master bedroom.
Answer:
The new carpet for the master room will cost $379.30
Step-by-step explanation:
The bedroom is a rectangle of dimensions:
[tex]4\sqrt {3}+6\sqrt {3}=10\sqrt {3}~ft[/tex]
[tex]6\sqrt {6}~ft[/tex]
Thus, the area of the master bedroom is:
[tex]A=10\sqrt {3}~ft*6\sqrt {6}~ft[/tex]
Multiply the coefficients and the arguments:
[tex]A=60\sqrt {18}~ft^2[/tex]
Calculating:
[tex]A=254.56~ft^2[/tex]
The carpet unit cost is $1.49 per square foot, thus the total cost of the new carpet is:
$1.49*254.56=$379.30
The new carpet for the master room will cost $379.30

cos4θ-cos2θ/sin4θ+sin2θ
Answers:
A. cotθtanθ
B. -cotθ
C. -tanθ
D. -1
Recall the double angle identities:
cos(2θ) = 1 - 2 sin²(θ)
sin(2θ) = 2 sin(θ) cos(θ)
With some rewriting, we can get
cos(4θ) - cos(2θ) = 2 cos²(2θ) - 1 - cos(2θ) = (2 cos(2θ) + 1) (cos(2θ) - 1)
and
sin(4θ) + sin(2θ) = 2 sin(2θ) cos(2θ) + sin(2θ) = sin(2θ) (2 cos(2θ) + 1)
The numerator and denominator both share a factor of 2 cos(2θ) + 1; canceling them leaves us with
(cos(2θ) - 1) / sin(2θ)
Replace cos(2θ) = 1 - 2 sin²(θ) and sin(2θ) = 2 sin(θ) cos(θ) :
((1 - 2 sin²(θ)) - 1) / (2 sin(θ) cos(θ))
-2 sin²(θ) / (2 sin(θ) cos(θ))
- sin(θ) / cos(θ)
- tan(θ)
so the answer is C.
Answer:
(cos4θ-cos2θ)/(sin4θ+sin2θ)
-[2sin((4θ+2θ)/2)sin(2θ-4θ)/2)]/[2sin((4θ+2θ)/2)cos (4θ-2θ)/2)]-sinθ/cosθ-tanθC. -tanθ is your answer.

Step-by-step explanation:
When you add all rentals together you should get 125, after this you see what the problem is asking, in our case, the probability of not renting a drama, as said, our total is 125. When we look at how many dramas have been rented you get 25, simply, you divide 125 by 25, therefore you should get 5, so now, we know that there is a 1/5 possibility for getting it but because its not 5/5.
Thus, there should be 4/5 which is the probability of it not getting chosen.

A car tire has a radius of 10.4 inches. What distance will the tire travel after 20 rotations?
Answer:
Distance traveled after 20 rotations = 1306.24 inches
Step-by-step explanation:
r = 10.4 inches
Distance traveled in one rotation = Circumference of the car tire
Circumference of the car tire = 2πr
= 2 * 3.14 * 10.4
= 65.312 inches
Distance traveled after 20 rotations = 65.312 * 20
= 1306.24 inches

Due to conservation efforts, the panda bear has been removed from the endangered species list. There are now 15,000 in the world, and the population is expected to grow by 10% yearly. Write an equation that models this scenario.
1. y = 15,000(1.10)x
2. y = 15,000(0.90)x
3. y = 15,000(0.10)x
4. y = 15,000(1.90)x
Answer:1
Step-by-step explanation:
you have to put the 1 infornt of the .10 if youre adding 10% more
Answer:
y = 15,000(1.10)x
Step-by-step explanation:
The equation y = 15,000(1.10)x represents the population of panda bears over time. In this equation, "y" represents the population, "15,000" represents the initial population of panda bears, and "1.10" represents the growth rate of 10% per year. The variable "x" represents the number of years.
By raising the growth rate of 1.10 to the power of "x" (the number of years), we account for the compounding effect of the growth rate over time. This equation allows us to calculate the population of panda bears after a specific number of years by multiplying the initial population (15,000) by the growth rate (1.10) raised to the power of the number of years.
For example, if we wanted to find the population after 5 years, we would substitute "x" with 5 in the equation:
y = 15,000(1.10)^5
This would give us the population of panda bears after 5 years, taking into account the annual growth rate of 10%.

Step-by-step explanation:
Answer:
1) 15x + 3y = 27 in slope-intercept form.
→y=-5x+9
→m =-5
→b =(0,9)
2) 15x − 3y = 12 in slope-intercept form.
→y =5x-4
→m =5
→b =(0,-4)
3) 2y = 16 in slope-intercept form.
→y =8
→m =0

Time traveler can take 5 books with him and he has 79 books to choose from how many different ways can the books be selected
We are given:
The time-traveller has 79 books, but he can only take 5 books
since we need to find the number of ways he can choose 5 books, we know that the order in which he takes the books does NOT matter
Hence, we will use combination
Finding the number of ways:
Since we will use combination, ₇₉C₅
We know that the formula for combination is (n!) / (r!(n-r)!)
₇₉C₅ = 79! / 5!(74!)
₇₉C₅ = 22,537,515
Therefore, the time traveller can choose 5 books in 22,537,515 different ways

A motorcycle make 100 revelation in moving a distance of 220m find the diameter of the wheel
Answer:
Step-by-step explanation:
If it goes 220 meters and has made 100 revolutions that means that each revolution is 220 meters / 100 = 2.2 meters.
That's the same thing as saying that the wheel has a circumference of 2.2 meters.
Circumference = 2*pi * r = pi * d
2 = pi * d
2 = 3.14 * d
2/3.14 = d
d = 0.6369 meters

B : x = - 3
C : x = 0
D : x = 2
E: x = 3
F : x = - 1
Answer:
