Find the value of x. Round to
the nearest tenth.
Х
15°
300
X = ?
Answer:
80.4
Step-by-step explanation:
Use the tan formula
The value of X is approximately 80.38 units.
Here, we have,
To find the value of X, we can use trigonometric functions.
In this case, we'll use the tangent function, which relates the angle and the sides of a right triangle.
The tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
In this scenario, we have the angle between the hypotenuse and the base as 15°, and the base of the triangle is given as 300 units.
Using the tangent function, we can set up the equation:
tan(15°) = X / 300
Now, let's solve for X:
X = 300 * tan(15°)
Using a calculator, we find:
X ≈ 80.384
Rounding to the nearest tenth, the value of X is approximately 80.38 units.

Aden gets paid daily for the work she does and she does not work on Sundays. Last year which was n ot a leap year had 52 Sundays. She got Dhs 354003 as her annual salary last year. If the March of last year had 5 Sundays, how much did she earn in that month?
Answer: Dhs 29312.4
Step-by-step explanation:
For a leap year, we should note that there are 366 days. Since there were 52 Sundays, the number of days worked by Aden will be:
= 366 - 52
= 314 days
Since she got Dhs 354003 as her annual salary last year, the amount received per day will be:
= 354003 / 314
= Dhs 1127.4
The amount earned in March will be:
= (31 - 5) × 1127.4
= 26 × 1127.4
= Dhs 29312.4

Find the measure of the numbered angle
Answer:
1 = 50°, 2 = 130°, 3 = 50°, 4 = 130°, 5 = 40°, 6 = 140°, 7 = 90°, 8 = 140°
Step-by-step explanation:
The sum of the angles of a triangle is 180°. A flat angle measures 180° as well.
Angle 1: 180 - 90 - 40 = 50°
Angle 2: 180 - 50 = 130°
Angle 3: 180 - 130 = 50°
Angle 4: 180 - 50 = 130°
Angle 5: 180 - 90 - 50 = 40°
Angle 6: 180 - 40 = 140°
Angle 7: 180 - 90 = 90°
Angle 8: 180 - 40 = 140°

x= -1/5; f(x) = (25/2)x + (-91/2) =
Answer:
Write the problem as a mathematical expression.
X=−1/5; f(x)=(25/2)x+(−91/2)
Replace the variable x with x=−1/5 in the expression.
f(−1/5)=(25/2)(−1/5)−91/2
Simplify the result.

You can walk 3/4 of a mile in 1/6 of an hour (10 minutes). How far can you walk in an hour?
Answer:
4 and 1/2 miles (or 9/2 miles)
Step-by-step explanation:
I would set this up as a proportion
3/4 x
10 60
Cross multiply
60 x 3/4 = 45
Divide
45/10 = 4.5
4.5 = 4 and 1/2 miles
1) Give an example of a rational number AND an irrational number.
What is the difference between them?
2) What is the decimal equivalent of your two examples?
3) Can every repeating decimal be written as a rational number? Explain why or why
not.
Answer:
Step-by-step explanation:
A rational number is one that can be expressed as a fraction. Pi cannot be. If I tell you that the 2000th digit of pi is an 8 (which it probably isn't) and I ask you to tell me the 2001 value of pi, you have no better odds that 1/10 of getting it right.
A rational number can always be reduced to a fraction. 20 1/2 can be expressed as a fraction. It is 20.5
Pi is irrational. I don't know the value of pi beyond what a calculator can tell me. 3.14159265 The next digit is a 4. I know this only because that is what the calculator tells me.
Repeating decimals call always be represented as a fraction. For ex
x = 0.123123123123123
1000x = 123.123123123123
x = .123123123123123 Subtract
999x = 123
This comes about because in both cases what is after the decimal is the same.
x = 123/999 = 41/333

Answer: c
Step-by-step explanation:
Hadley was going out with her friends for dinner. The equation c = x + 0.07x + 0.18x gives the total cost c of her meal, where x is the cost before tax and tip. The restaurant charges 7% sales tax and she plans to leave an 18% tip. She knew that she can only spend $18. What is the maximum amount Hadley can spend before tax and tip?
Answer:
$14.4
Step-by-step
c = x + 0.07x + 0.18x
18 = x + 0.07x + 0.18x
18 = 1.25x (simplify)
14.4 = x (divide both sides by 1.25)

PLS HELP ME! Joye has a circular garden with a diameter of 24 feet. If she uses 2 cups of fertilizer for every 10 square feet, how much fertilizer will Joye use for her garden? Use 3.14 for pi
Answer:
90.5 cups
Step-by-step explanation:
Step one:
Given data
diameter= 24ft
radius= 12 ft
area= πr^2
Area= 3.142*12^2
Area= 3.142*144
Area= 452.448 ft^2
Hence if
2 cups of fertilizer for every 10 square feet
x cups will do for 452.448 ft^2
cross multiply we have
x= 452.448 *2/10
x=904.896/10
x=90.5 cups
I need help please!
Answer/Step-by-step explanation:
Area of trapezium = ½*(AD + BC)*AB
Area = 42 cm²
AD = (x + 8) cm
BC = (x + 5) cm
AB = x cm
Plug in the values into the equation
42 = ½((x + 8) + (x + 5))*x
42 = ½((x + 8 + x + 5)*x
42 = ½(2x + 13)*x
Multiply both sides by 2
42*2 = (2x + 13)*x
84 = 2x² + 13x
2x² + 13x = 84
Subtract both sides by 84
2x² + 13x - 84 = 0

In a study of facial behavior, people in a control group are timed for eye contact in a 5- minute period. Their times are normally distributed with a mean of 184 seconds and a standard deviation of 55 seconds. For a randomly selected person from the control group, find the probability that the eye contact time is greater than 230 seconds
Answer:
0.20148
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 230
μ is the population mean = 184
σ is the population standard deviation = 55
z = 230 - 184/55
z = 0.83636
P-value from Z-Table:
P(x<230) = 0.79852
P(x>230) = 1 - P(x<230) = 0.20148
Therefore, the probability that the eye contact time is greater than 230 seconds is 0.20148
