16/30=20/x what is x?
Answer: 75/2
Step-by-step explanation: Math
Answer:
75/2
Step-by-step explanation:
16/30=20/x
Cross multiply
16*x=(20)*(30)
16x=600
Divide both sides by 16.
16x /16 = 600 /16
x=75/2

Explain why sine of an angle greater than 180° and less than 360° is negative.
9514 1404 393
Explanation:
The sine of an angle in standard position is the y-coordinate of the intersection of its terminal ray with the unit circle. When the angle is in the range 180° < θ < 360°, that point of intersection is in quadrant III or IV, where y-coordinates are negative.

That is where the sine curve is below the x-axis.

i don't know specifically what you are looking for but:
Direction: Opens Up
Vertex: (1, -1)
Axis of Symmetry: x = 1
and i attached the graph
Answer: x = √(((-F - 4)^2)/16 - 1/2) + (F + 4)/4 or x = (F + 4)/4 - √(((-F - 4)^2)/16 - 1/2)
Step-by-step explanation:
Solve for x:
F x = 2 x^2 - 4 x + 1
Subtract 2 x^2 - 4 x + 1 from both sides:
-2 x^2 + F x + 4 x - 1 = 0
Collect in terms of x:
-1 + x (F + 4) - 2 x^2 = 0
Divide both sides by -2:
1/2 + 1/2 x (-F - 4) + x^2 = 0
Subtract 1/2 from both sides:
1/2 x (-F - 4) + x^2 = -1/2
Add 1/16 (-F - 4)^2 to both sides:
1/16 (-F - 4)^2 + 1/2 x (-F - 4) + x^2 = 1/16 (-F - 4)^2 - 1/2
Write the left hand side as a square:
(1/4 (-F - 4) + x)^2 = 1/16 (-F - 4)^2 - 1/2
Take the square root of both sides:
1/4 (-F - 4) + x = √(1/16 (-F - 4)^2 - 1/2) or 1/4 (-F - 4) + x = -√(1/16 (-F - 4)^2 - 1/2)
Subtract 1/4 (-F - 4) from both sides:
x = √(((-F - 4)^2)/16 - 1/2) + (F + 4)/4 or 1/4 (-F - 4) + x = -√(1/16 (-F - 4)^2 - 1/2)
Subtract 1/4 (-F - 4) from both sides:
Answer: x = √(((-F - 4)^2)/16 - 1/2) + (F + 4)/4 or x = (F + 4)/4 - √(((-F - 4)^2)/16 - 1/2)
Solve for u: 2(u + 6) - 8 > 3(u - 5)
Answer:

Step-by-step explanation:
First get rid of the brackets:
[tex]2u + 12 - 8 > 3u - 15[/tex]
Then simplify:
[tex]2u + 4 > 3u - 15[/tex]
Get all the u's on one side:
[tex]2u - 3u > - 15 - 4[/tex]
Simplify and find u:
[tex] - u > - 19[/tex]

Step-by-step explanation:
What are the solutions to the quadratic equation below? X^2-8x+16
(₋4)²
how i got it -
1st i used the sum-product pattern
x² - 8x + 16
x² -4-4+16
then, found the common fact from the two pairs
x² - 4 - 4 + 16
(-4) - 4(-4)
rewrite in factored form
(x-4)-4(-4)
(-4) (-4)
combine to a square
(-4) (-4)
Answer:
x=4*
Step-by-step explanation:
*THIS IS ASSUMING THAT THIS EQUATION IS EQUAL TO ZERO
X^2-8x+16=0
Let's solve this equation by factoring. First, we need to find factors of 16 that add to -8. We find that those factors are -4 and -4. X^2 is simply x times x.
Therefore, when it is factored It should look like this:
(x-4)(x-4)=0
Now we take both factors and set them equal to zero:
x-4=0; x-4=0
In both of these equations we just need to add 4 to both sides.
x=4; x=4
x=4

Use the information to answer the following questions. The angle measures of a triangle are shown. Angle A: (5x – 5) degrees Angle B: (3x + 3) degrees Angle C: (5x) degrees What expression can be written to represent the sum of the angle measures?
Answer:
5x-5+3x+3+5x=180
Step-by-step explanation:
As it is a triangle, sum of all angles is 180.
5x-5+3x+3+5x=180
13x=182, x=14
The expression that represents the measure sum of the angle is
(5x – 5)° + (3x + 3)° + (5x)° = 180°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We also know that sum of all the interior angles of a triangle is 180°.
The given statement can be written as,
∠A + ∠B + ∠C = 180°.
(5x – 5)° + (3x + 3)° + (5x)° = 180°.
13x - 2° = 180°.
13x = 180° + 2°.
13x = 182°.
x = 14°.
We can also find the measure of each angle now by substituting the value of x in ∠A, ∠B, and ∠C.

Read the excerpt from The Call of the Wild.
Then an old wolf, gaunt and battle-scarred, came forward. Buck writhed his lips into the preliminary of a snarl, but sniffed noses with him, Whereupon the old wolf sat down, pointed nose at the moon, and broke out the long wolf howl. The others sat down and howled. And now the call came to Buck in unmistakable accents. He, too, sat down and howled. This over, he came out of his angle and the pack crowded around him, sniffing in half-friendly, half-savage manner. The leaders lifted the yelp of the pack and sprang away into the woods. The wolves swung in behind, yelping in chorus. And Buck ran with them, side by side with the wild brother, yelping as he ran.
Which theme does this passage illustrate?
A good leader is strong and intelligent and treats his followers well.
Only the strong survive in the wilderness.
The only way to learn something is to try it.
The desire to fight for power is an instinct.
Answer:
The passage is centered on the theme of belonging in a certain pack or group. Buck may be a bit different from the others but as Buck tried to be like them and did what they usually do, it gathered the trust of the pack especially the leaders. To belong in a group, one should gain their trust.

An airline tracks data on its flight arrivals. Over the past six months, 65 flights on one route arrived early, 273 arrived on time, 218 were late, and 44 were cancelled. What is the probability that a flight is early
Answer:
0.108
Step-by-step explanation:
Given that:
Number of flights reached early = 65
Number of flights reached on time = 273
Number of flights reached late = 218
Number of flights canceled = 44
To find:
The probability that a flight is early.
Solution:
First of all, let us have a look at the formula for probability of an event E.
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, Event E is that the flight is early.
Number of favorable cases is equal to the number of a flights which reached early i.e. 65
Total number of cases is the total number of flights.
i.e. 65 + 273 + 218 + 44 = 600
So, the required probability is:
[tex]P(E) = \dfrac{65}{600} = \bold{0.108}[/tex]

The rabbit population in a certain area is 200% of last year's population. There are 300 rabbits this year. How many were there last year?
Answer:
There were 650 rabbits last year
The percentage of a quantity can be found by first changing the percent into a fraction and then multiplying it to the value of that quantity. Last year the number of rabbits was 150.
What is percentage?A percentage is a value that indicates the hundredth part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The population of rabbit this year is 300.
The percentage of the population with respect to the last year is 200%.
Suppose the population of rabbits last year was P.
Then as per the question, following expression can be written,
200% of N = 300
⇒ (200 / 100) × N = 300
⇒ 2N = 300
⇒ N = 150
Hence, the population of the rabbits last year was 150.
