Answer:
x = 3.4
Step-by-step explanation:
recall that for a right angle with an internal angle θ,
cos θ = adjacent length / hypotenuse
in our case,
θ = 55 deg
adjacent length = x units
hypotenuse = 6 units
substitute these into the formula above
cos θ = adjacent length / hypotenuse
cos 55 = x / 6 (multiply both sides by 6)
x = 6 cos 55 (use calculator)
x = 3.4415
x = 3.4 (rounded to nearest tenth)

A student cycles a distance of 63 km in less
than 3 hours. What is the average speed?
Answer:
About About 21 km/h
Step-by-step explanation: If they travel 63 km in 3 hours then all it is is just 63 divided by 3 or 63/3.
The average speed for the cycle will be 21 km per hour.
What is an average speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.
The average speed is defined as the ratio of the total distance traveled and the total time taken by the object.
Given that A student cycles a distance of 63 km in less than 3 hours. The average speed is calculated as:-
Average speed = Distance / time
Average speed = 63 / 3
Average speed = 21 km / hr

An independent study commissioned by the stadium showed that running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets. How long should the stadium run the cable ad in order to reach this target?
Answer
I think 55 times
Step-by-step explanation:
13,200/1,200 = 11
5/1200 = x/13,200
so if 1,200*11=13, 200 then 5*11= 55.
btw , could u give me the brainliest if i am right?
The total time the stadium runs the cable ad in order to reach this target is 11 days and this can be determined by using the unitary method.
Given :
Running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets.The following steps can be used in order to determine the total times the stadium run the cable ad in order to reach this target:
Step 1 - The unitary method can be used in order to determine the total times the stadium runs the cable ad in order to reach this target.
Step 2 - According to the given data, running a cable TV ad 5 times daily for a week generated 1,200 ticket sales.
Step 3 - If running TV ad 5 times daily sales 1200 tickets then to sell 13200 tickets the total times the ad is running is:
[tex]=\dfrac{13200}{1200}\times 5[/tex]
= 55 times
Step 4 - Now, if 5 times ad running in one day then 55 times ad running in:
[tex]=\dfrac{55}{5}\times 1[/tex]
= 11 days

At an end of the year sale, Gabriela bought more than 12 bottles of hand soaps and lotions. If x represents the number of hand soaps and y represents the number of lotions she bought, which inequality best represents her purchase?
x + y 12
x + y ≤ 12
x + y ≥ 12
Answer:
the answer is b
Step-by-step explanation:
edge 2021
The inequality which best represents the purchase is x + y > 12.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given that,
At an end of the year sale, Gabriela bought more than 12 bottles of hand soaps and lotions.
Let x represents the number of hand soaps she bought.
Let y represents the number of lotions she bought.
x + y is more than 12.
So the inequality is,
x + y > 12

A population of values has a normal distribution with μ=152.8 and σ=26.2 . You intend to draw a random sample of size n=94 . Find the probability that a single randomly selected value is less than 149.6. P(X < 149.6) =
Answer:
P(x < 149.6) = 0.11821
Step-by-step explanation:
We start by calculating the z-score of the parameter given
Mathematically,
z-score = (x-mean)/SD/√n
z-score = (149.6-152.8)/26.2/√94
z-score = -3.2/2.70
z-score = -1.18
So the probability we want to calculate is;
P( x < -1.18)
we can use the standard normal distribution table to get this
From the standard normal distribution table, this value is 0.11821

How far from the door must a ramp begin in order to rise 3 feet with an 8 degree angle of elevation
Answer:
Step-by-step explanation:
We know that the angle of elevation is 8 degrees.
We know that the height of the opposite side of the angle is 3 feet.
We want to know the adjacent side (the side from the start of the ramp to the bottom of the opposite side)
We can do this with tangent
[tex]tan(8) = \frac{3}{adj} \\adj = \frac{3}{tan(8)} \\adj = 21.34611 feet[/tex]
The distance between the ramp and the door can be calculated using the principle of Pythagoras, Hence, the distance should be 21.34 feets
Angle of elevation = 8°Rise = opposite = 3 feets Distance, d = adjacentUsing SOHCAHTOA :
Tanθ = Opposite / Adjacent
Tan(8°) = 3 / d
0.1405408 = 3 / d
0.1405408d = 3
Divide both sides by 0.1405408 to isolate d
0.1405408d / 0.1405408 = 3 / 0.1405408
d = 21.34 feets
Therefore, the distance of the ramp from the door should be 21.34 feets

Identify the property on this equation 5(a + 3b) = 5a + 15b
Answer:
??????????????????????
Step-by-step explanation:
Answer: Distributive Property
The term "distribution" is also used in place of "distributive"
This property says
x*(y+z) = x*y + x*z
We multiply the outer term x with each inner term (y and z). Then we add the results.
In this case,
x = 5
y = a
z = 3b
So,
5(a+3b) = 5*a + 5*3b = 5a+15b

Deandre is going bowling with some friends. It costs $5 to rent a pair of bowling shoes & $3 per game. If Deandre spent $11, how many games did he bowl?
Answer:
2
Step-by-step explanation:
He played 2 games because he already paid $5 to rent a pair of bowling shoes and each game cost $5. So all you have to do is add 5+3 and that would give you 8. That's not quit 11 yet so add another 3. 8+3 would equal 11.

Find the area of this parallelogram.
5 cm height
7 cm width
Answer:
35 cm^2
Step-by-step explanation:
To find the area you need to find the width and height which we have.
Now all you need to do is to use the formula Height x Width= area
so replace height with 5 cm and width with 7 cm
5 cm x 7 cm = area
5 times 7 is 35 so the area of the parallelogram is 35 cm^2 (cm times cm is cm^2)
