If Y varies directly with X,
find y when X =24 if y =5
when X = 30.
Answer:
We get Y=4 when X =24
Step-by-step explanation:
If Y varies directly with X, find Y when X=24, if Y = 5 when X= 30.
We are given If Y varies directly with X, we can write:
[tex]Y\:\alpha\: X\\Y=kX[/tex]
Where k is constant of proportionality
We need to find Y when X=24, first we need to find k, the constant of proportionality.
Now, we are given: If Y = 5 when X= 30.
We can find value of k
[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]
So, k=1/6
Now, we will find Y when X = 24
and k=1/6
[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]
So, Y=4 when X =24.

Given sin x = 8/10, 90° <x< 180° and tan y = -12/5, 270° ≤y≤ 360°. Without finding the values for angle x and y, determine cos x cos y + sin x sin y / tan x - tan y.
Answer:[tex]-\frac{189}{208}[/tex]
Step-by-step explanation:
Given
[tex]\sin x=\frac{8}{10}[/tex]
x lies in the second quadrant where sin and cosec is positive and rest trigonometric functions are negative
so, [tex]\cos x=-\sqrt{1-sin ^2 x}\\\cos x=-\sqrt{1-(\frac{8}{10})^2}=-\sqrt{\frac{36}{100}}\\\cos x=-\sqrt{\frac{6}{10}}[/tex]
[tex]\tan x=\frac{\sin x}{\cos x}=-\frac{4}{3}[/tex]
similarly, [tex]\tan y=-\frac{12}{5}[/tex]
Also, y lies in 4 th Quadrant where cos and sec is positive and rest trigonometric functions are negative
[tex]\sec y=\sqrt{1+\tan ^2y}=\sqrt{1+(-\frac{12}{5})^2}\\\sec y=\frac{13}{5}\\\cos y=\frac{5}{13}\\\sin y =\frac{\tan y}{\cos y}=-\frac{12}{13}[/tex]
Now putting the values
=[tex]\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{(\frac{-6}{10})(\frac{5}{13})+(\frac{8}{10})(\frac{-12}{13})}{(\frac{-8}{6})-(\frac{-12}{5})}\\\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{\frac{-126}{130}}{\frac{16}{15}}=-\frac{189}{208}[/tex]

Convert the following equation from standard form to slope-intercept form.
x +y = -3
Answer:
y=-x-3
Step-by-step explanation:
Slope intercept form is y=, and so we had to get the x to the other side. To do that you would subtract x from each side and then you get your answer.

What expression is equivalent to
4/9(2n - 3)
Answer:8/9 n- 12/9
Step-by-step explanation: You do distributive property.Which is 4/9 times 2 n but you make both 4/9 and 2 to a fraction which is 4/9 times 2/1 which gives you 8/9 .Next you do 4/9 times 3 but make to a fraction both which is 4/9 times 3/1 which gives you 12/9 .Next you take the 8/9 n and 12/9 and you subtract it .Which gives you 8/9 n- 12/9 as your expression.

It takes Maria 10 hours to pick forty bushels of apples. Kayla can pick the same
amount in 12 hours. How long will it take if they work together? Round your answer
to the nearest tenths place.
Answer:
5.3
Step-by-step explanation:
It will take a time 0f 5.5 hours to pick 40 bushels of apple if they worked together.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p: q : : r : s.
This is same as p : q = r : s or p/q = r/s
Given that,
Amount of bushels picked by Maria in 10 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/10 = 4
Amount of bushels picked by Kayla in 12 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/12 = 3.333
Amount of apple picked by both Maria and Kayla in 1 hour if they worked together = 4 + 3.333 = 7.333
Let x be the time taken to pick 40 bushels of apple by both.
Using proportional concept,
x / 40 = 1 / 7.333
x = 40 / 7.333
x = 5.4548 ≈ 5.5 hours
Time taken if they both worked together is 5.5 hours.

Write the final equation using the slope-intercept form perpendicular to 3y = x − 4 and passes through the point (−2, 1)
Answer:
y=-3x-5
Step-by-step explanation:
given equation:
3y=x-4
slope intercept form is y=mx+b
(m is the slope, b is the y intercept)
divide by 3
y=1/3x-4/3
perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.
so to find the slope of the perpendicular line, use this equation:
1/3m=-1
multiply by 3
m=-3
the slope of the new line is -3.
here is our equation so far:
y=-3x+b
now, we need to find b.
Since the equation of the line passes through the point (-2,1) we can substitute that into the equation to find b
1=-3(-2)+b
multiply
1=6+b
subtract 6
-5=b
so the line is y=-3x-5
Hope this helps!
