Answer:
12: 48
Step-by-step explanation:
There are a total of 5 parts in 1:4, so one part would be:

This means the ratio is 12: 4 * 12 or 12: 48
I NEED HELP. Plz ignore my handwriting
Answer:
Part A: 3x-8=2+12
3x-8=14
3x=22
x=22/3
Part B:
Since we know that two angles are equal to 14 because they are vertical angles, we have 360 = 28+2y. Solving for y we get
332 = 2y
166 = y.

Tyler is observing the ascent of a steel beam being lifted by a crane from a position about 250 ft away. What trigonometric function models the height h in feet of the beam as a function of the angle of inclination θ from Tyler's position to the steel beam
Answer: [tex]h=250 \tan \theta[/tex]
Step-by-step explanation:
Given
Tyler is 250 ft away from the crane
The angle of inclination is [tex]\theta[/tex]
Using the figure, we can write heigh h as
[tex]\Rightarrow \tan \theta =\dfrac{h}{250}\\\\\Rightarrow h=250\tan \theta[/tex]

A rectangular basketball court is in the center of a larger rectangular field. The basketball court measures (9x + 4) ft long and 5x ft wide. The field measures (11x + 4) ft long and 7x ft wide. What is the area of the field that is not covered by the basketball court?
Answer:
2(11x+4)+2(7x)=(22x+8)*14x=308x^{2}+112x
2(9x+4)+2(5x)=(18x+8)*10x=180x^{2}+80x
308x^{2}+112x-180x^{2}-80x=128x^{2}+32x- the area that is not covered

How can you tell if a function is quadratic given a table of values?
Answer: When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

If the constant bounding the error in the Euler method is 0.2 and you wanted a 9 decimal place accuracy, how many steps, n, would you need ensure this accuracy?
Answer:
The answer is "13".
Step-by-step explanation:
Euler method=e=0.2 constantly binding the error
Precision should be 9 decimal places=0.000000001
The number of steps should be n.
In order to guarantee precision,
[tex]\to 0.2^n> 0.000000001\\\\ \to n> \frac{\log(0.000000001) }{\log(0.2)} \\\\ \to 12.876 \approx 13[/tex]

The area of rectangular is 64m the length of the pool is 12 m less that the width .The situation can be represented by the equation x
Answer:
Width = 16 m
Length = 4 m
Step-by-step explanation:
The area of rectangular is 64m² the length of the pool is 12 m less that the width . The situation can be represented by the equation x
Area of a rectangle = Length × Width
L = W - 12
Hence:
64 = (W - 12) × W
64 = W² - 12W
W² - 12W - 64 = 0
Factor using
(W + 4)(W - 16) = 0
Width = 16m
Length = W - 12
Length = 16 m - 12 m
= 4 m
factor completely 21x^3+35x^2+9x+15
Answer:

Step-by-step explanation:
Factor : 21x^3+35x^2+9x+15
21x^3+35x^2+9x+15
=(3x+5)(7x^2+3)

Step-by-step explanation:
If a f=23cm, find the length of EC.
Answer:
37.3
Step-by-step explanation:
The length of EC shown in the diagram is 37.3.
"To understand the calculation, check below."
TrianglesΔBE -ΔAE= ΔAB
ΔAB=180°-148°
ΔAB=32°
ΔBE -ΔAB-ΔBC=ΔCD (Congruent angles)
ΔCD = 180-32-87
ΔCD =62
EC=61+32
EC=93
L=93•2pi23/360
L=37.3
Therefore , EC=37.3

Same as before this test... is just driving me crazy I'm blowing all my points through these so...
Answer and Step-by-step explanation:
For this, you would need to use the trigonometric function Sine and cosine.
The trig equations are:
sin(θ) = [tex]\frac{opposite - side}{hypotenuse}[/tex]
cos(θ) = [tex]\frac{adjacent-side }{hypotenuse}[/tex]
Let's start with Sine:
sin(60) = [tex]\frac{x}{10\sqrt{3} }[/tex]
Multiply both sides of the equation by [tex]10\sqrt{3}[/tex].
[tex]10\sqrt{3} (sin(60)) = x[/tex]
Input into calculator and solve.
x = 15
Now for Cosine:
cos(60) = [tex]\frac{y}{10\sqrt{3} }[/tex]
Multiply both sides of the equation by [tex]10\sqrt{3}[/tex].
[tex]10\sqrt{3} (cos(60)) = x[/tex]
Input into calculator and solve.
y = [tex]5\sqrt{3}[/tex]
x = 15
y = [tex]5\sqrt{3}[/tex]
These are the answers.
I hope this helps!
#teamtrees #PAW (Plant And Water)
Step-by-step explanation:
It's a right triangle with one of the angles being 60°. This means that the leftover angle is 30°. This allows me to use the attached screenshot as a reference, so please check it out if you want to understand how to easily solve those types of equations in the future. Anyway, we can specify the hypotenuse as [tex]a[/tex] .
First, let's calculate the value of [tex]y[/tex].
[tex]a[/tex] = [tex]10\sqrt{3}[/tex]
[tex]y[/tex] = [tex]\frac{a}{2}[/tex]
[tex]y[/tex] = [tex]\frac{10\sqrt{3} }{2}[/tex]
[tex]y[/tex] = [tex]5\sqrt{3}[/tex]
----
Now, let's get to [tex]x[/tex]
[tex]a[/tex] = [tex]10\sqrt{3}[/tex]
[tex]x[/tex] = [tex]\frac{a\sqrt{3} }{2}[/tex]
[tex]x[/tex] = [tex]\frac{10 \sqrt{3} * \sqrt{3}}{2}[/tex]
[tex]x[/tex] = [tex]\frac{10 * 3}{2}[/tex]
[tex]x[/tex] = [tex]\frac{30}{2}[/tex]
[tex]x[/tex] = [tex]15[/tex]
----
[tex]x[/tex] = [tex]15[/tex] and [tex]y[/tex] = [tex]5\sqrt{3}[/tex]
