Find the value of x. Round the length to the nearest tenth. The diagram is not drawn to scale.
Answers
Answer:
x ≈ 2879.4 m
Step-by-step explanation:
Measure of ∠DAC = 10°
Measure of ∠DAB = 90°
Measure of ∠BAC = 90° - 10° = 80°
By applying cosine rule in ΔABC,
cos(80°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AB}{AC}[/tex]
0.17365 = [tex]\frac{500}{x}[/tex]
x = [tex]\frac{500}{0.17365}[/tex]
x = 2879.36
x ≈ 2879.4 m

Complete Question
In a certain country the heights of adult men are normally distributed with a mean of 69 inches and a standard deviation of 2.2 inches. The country's military requires that men have heights between 64.6 inches and 73.4 inches.
What percentage of this country's men are eligible for the military based on height?
Answer:
95.45 %
Step-by-step explanation:
We solve using z score formula
z-score iis z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 69
σ is the population standard deviation = 2.2
For x= 64.6 inches
z = 64.6 - 69/2.2
z = -2
Probability value from Z-Table:
P(x = 64.6) = 0.02275
For x= 73.4 inches
z = 73.4 - 69/2.2
z = 2
Probability value from Z-Table:
P(x<73.4) = 0.97725
The probability of this country's men are eligible for the military based on height is calculated as:
p(x = 73.4) - p( x = 64.6)
0.97725 - 0.02275
= 0.9545
Converting to Percentage is
= 0.9545 × 100
= 95.45 %

How do you graph a quadratic function?
Answers
Answer:
Step-by-step explanation:
Compare the equation with the standard form, y=ax2+bx+c . Since the value of a is positive, the parabola opens up.
So, y=0 implies, by the zero product property, x+4=0 or x−2=0 .
Substitute x=−1 in the equation y=−x2−2x+8 to find the y -coordinate of the vertex.

Answer:
Step-by-step explanation:
Sin(x) = opposite / hypotenuse.
opposite = 28 The opposite is not connected to the angle.
hypotenuse= 35
Sin(x) = 28/35 = 4/5
Cos(x) = adjacent / hypotenuse.
The adjacent side is part of the angle
adjacent = 21
hypotenuse = 35
Cos(x) = 21 / 35 = 3/5
Tan(x) = opposite / adjacent
opposite = 28
adjacent = 21
Tan(x) = 28/21
Tan(x) = 4/3

now we add, right? 9/1 ( same as 9 ) + 1/9 = ?
does it want it in fraction, decimal, or whole?
Answer:
9 1/9 is the answer
Step-by-step explanation:
1/3 to the power of 2 becomes 1/9
3 to the power of 2 becomes 9
[tex]\frac{1}{9} + 9[/tex]
whole numbers always go over a 1
[tex]\frac{1}{9} + \frac{9}{1}[/tex]
make 9/1 have the same denominator as 1/9 by multiplying the top and bottom with 9
[tex]\frac{1}{9} + \frac{81}{9}[/tex] [tex]= \frac{82}{9}[/tex]
the simplify 82/9

Answers
Answer:
740 total students, 481 total girls
Step-by-step explanation:
Let x be the total number of students and y be the total number of girls
x -
You know that 35% of the students is 259 students. If you convert this into algebra, you can write : 0.35x = 259, after simplifying, you know that x = 740.
y-
You know that 35% of the students are boys, so 65% must be girls. You can say that 65% of x is y and write the equation 0.65(740)=y. After simplifying, you can see that y = 481.

Let's solve your equation step-by-step.
4x + x + 5 − 9 + x = −3 − 7 + x
Step 1: Simplify both sides of the equation.
4x + x + 5 − 9 + x = −3 − 7 + x
4x + x + 5 + −9 + x = −3 + −7 + x
( 4x + x + x ) + ( 5 + −9 ) = ( x ) + ( −3 + −7 )
( Combine Like Terms )
6x + −4 = x + −10
6x − 4 = x − 10
Step 2: Subtract x from both sides.
6x − 4 − x = x − 10 − x
5x − 4 = −10
Step 3: Add 4 to both sides.
5x − 4 + 4 = −10 + 4
5x = −6
Step 4: Divide both sides by 5.
5x / 5 = −6 / 5
x= −6 / 5
Answer:
x= −6 / 5
