Answer:
height ≈ 178.3 m
Step-by-step explanation:
∠ ACB = 27° ( alternate angles )
Using the tangent ratio in the right triangle
tan27° = \(\frac{opposite}{adjacent}\) = \(\frac{AB}{BC}\) = \(\frac{AB}{350}\) ( multiply both sides by 350 )
350 × tan27° = AB , then
AB ≈ 178.3 ( to 1 dec. place )
The height of the plane is approximately 178.3 m

Find x (circle)
(Btw I don’t know if 5.6 is correct so just ignore that)
Answer:
A. 11.2
Step-by-step explanation:
But this has nothing to do with 5.6 × 2. Erase that! Lol.
You have a right triangle here. The only thing to do with the circle is that there are two radii (plural of radius) shown. So they have to be the same measure.
The unmarked "bottom" of the triangle, the short leg, is a radius, so it too, is 8.4.
The hypotenuse of the right triangle, the side on the right, the longest side is 5.6 + 8.4.
The hypotenuse is 14.
Let's do some Pythagorean Theorem.
Leg^2+ leg^2=hypotenuse^2
you know,
a^2 + b^2 = c^2
fill in what we know.
8.4^2 + b^2 = 14^2
simplify.
70.56 + b^2 = 196
subtract 70.56
b^2 = 125.44
squareroot both sides
b = 11.2

Airlines have increasingly outsourced the maintenance of their planes to other companies. A concern voiced by critics is that the maintenance may be less carefully done so that outsourcing creates a safety hazard. In addition, flight delays are often due to maintenance problems, so one might look at government data on percent of major maintenance outsourced and percent of flight delays blamed on the airline to determine if these concerns are justified. This was done, and data from 2005 and 2006 appeared to justify the concerns of the critics. Do more recent data still support the concerns of the critics? Here are data from 2014:

what is the distance between these two numbers -3 1/4 and 4 1/2
Answer:
7 3/4
Step-by-step explanation:
Method 1:
Step 1: Instead of subtracting you distribute the minus sign to the number in the parenthesis
4 1/2 - (-3 1/4) = 4 1/2 + 3 1/4
Step 2: Then you can just add
4 1/2 + 3 1/4= 7 3/4
Method 2:
If you dont know fractions transfer them into decimals. 1/2 = 0.5 and 1/4 = 0.25
Step 1: Instead of subtracting you distribute the minus sign to the number in the parenthesis
4.5 - (-3.25) = 4.5 + 3.25
Step 2: Add the numbers
4.5 + 3.25= 7.75
Step 3: Convert the decimal back into a fraction
7.75= 7 3/4

Which of the following is the graph of F(x) =-1/2x'4?
Answer:
A
Step-by-step explanation:
f(x) = -1/2x^4
Because x^4 is being multiplied n=by a negative number, the parabola will face down. That means it is between a and b. To figure out which graph it is, I look at points I could compare.
In graph A, when x=1, y < 1. In graph B, when x=1, y>1.
If i plug x= 1 into f(x), I get:
f(1) = -1/2(1)^4
f(1)=-1/2(1)
f(1)=-1/2
Because f(1) < 1, it is graph A.
What triangle is a 8cm triangle
Answer:
equilateral triangle.
solve each absolute value inequality and show its solution set |5t-1|>21
The solution of the absolute function is
t < -4
t > 22/5
In interval notation it will be (-∞,-4) ;(22/5,+∞).
What is absolute function?
An absolute value function is a function in algebra which consists of the variable in the absolute value bars. In general form of the absolute value function is f(x) = a |x - h| + k where h, k are constants and the most commonly used form of this function is f(x) = |x|. Here a = 1 and h = k = 0.
The Absolute Value term is |5t-1|
For the Negative case it will be -(5t-1)
For the Positive case it will be (5t-1)
at first we will solve for negative case:
-(5t-1) > 21
Multiplying by the minus sign we get,
-5t+1 > 21
Rearranging and Adding up we get,
-5t > 20
Dividing both sides by 5
-t > 4
Multiplying both sides by (-1) we get,
t < -4
Now we will solve for positive case:
(5t-1) > 21
Rearranging and Adding up we get,
5t > 22
Dividing both sides by 5 we get,
t > (22/5)
Hence the solution of the absolute function is
t < -4
t > 22/5
In interval notation it will be (-∞,-4) ;(22/5,+∞).

Las ecuaciones de la demanda y la oferta de cierto producto están dadas por espacio 4 q al cuadrado más p al cuadrado igual 1405 y p igual q más 10 donde p está en dólares por unidad y q está en unidades. Para un precio de 27 dólares por unidad, determine el gasto real del consumidor.
The actual consumer spending at a price of $27 per unit is $268.26.
How to calculate the priceSubstitute the given price into the supply equation to get the corresponding quantity supplied:
p = q + 10
27 = q + 10
q = 17
Substitute q = 17 into the demand equation to get the corresponding price:
4q² + p² = 1405
4(17)² + p² = 1405
p² = 1405 - 1156
p² = 249
p = 15.78
The actual consumer spending can be calculated by multiplying the quantity demanded by the price:

Eastern Aviation Equipment pays Donald Simmons a $1760 monthly salary plus a 12% commission on merchandise he sells each month. Assume Donald's sales were $90,800 for last month. Calculate the following amounts:
1. Amount of Commission:
2. Gross Pay:
The equation that represent the gross pay is y = 0.12x + 1760. The commission was $10896 and gross pay was $12656
What is an equation?An equation consists of numbers and variables linked together by mathematical operations to form an expression.
A linear equation is in the form:
y = mx + b
Where m is the rate of change and b is the initial value
Let y represent the gross pay for x total sales.
Donald Simmons a $1760 monthly salary plus a 12% commission on merchandise he sells each month, hence:
y = 1760 + 12% of x
y = 0.12x + 1760
Donald's sales were $90,800 for last month. Hence:
a) Commission = 0.12 * $90800 = $10896
b) Gross pay:
y = 10896 + 1760 = $12656

How did they get this answer? Somebody please help
Answer:
Step-by-step explanation:
x-intercept is where the line cuts the x-axis. That is, when y=0.
Substitute y=0 and we get:
\(0=\frac{1}{3} x-1\)
\(1=\frac{1}{3} x\)
\(x=3\)
So x-intercept is the point (3,0).

b. Solve the LP relaxation graphically. Round this solution to the nearest integer solution and check whether it is feasible. Then enumerate all the rounded solutions by rounding the solution for the LP relaxation in all possible ways (i.e., by rounding each noninteger value both up and down). For each rounded solution, check for feasibility and, if feasible, calculate Z. Are any of these feasible rounded solutions optimal for the IP problem?
Answer:
\((3,0)\)
Step-by-step explanation:
The integer points which fall in the common region bounded by the lines are
\((0,2),(2,3),(3,0)\)
Since, one of the points is \((2.22...,3.11....)\) we round it to \((2,3)\)
If we round up then the point will be \((3,4)\) which does not fall in the bounded region.
Also \(x_1\geq 0\) and \(x_2\geq 0\) no negative values are considered.
Applying in the values in the LP problem \(Z=5x_1+x_2\)
\(Z=5\times 0+2\\\Rightarrow Z=2\)
\(Z=5\times 2+3\\\Rightarrow Z=13\)
\(Z=5\times 3+0\\\Rightarrow Z=15\)
So, the LP problem is maximum at point \((3,0)\).

Show your work
Correct x and y
The solution to the system of equations is x = 1 and y = -3.
To solve the system of equations using the substitution or elimination method, let's start with the substitution method.
Given equations:
y = 4x - 7
4x + 2y = -2
We'll solve equation 1) for y and substitute it into equation 2):
Substituting y from equation 1) into equation 2):
4x + 2(4x - 7) = -2
4x + 8x - 14 = -2
12x - 14 = -2
Now, we'll solve this equation for x:
12x = -2 + 14
12x = 12
x = 12/12
x = 1
Now that we have the value of x, we can substitute it back into equation 1) to find y:
y = 4(1) - 7
y = 4 - 7
y = -3
Therefore, the solution to the system of equations is x = 1 and y = -3.
