The cost of feed for a cow in a month is $15.08
What is ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)
Similarly the ratio of the cost of cow's food to pig is 2:1
represent the cost of feed of a cow by x and the cost of feed for a pig to be y
therefore x= 2y
there are 46 cows, therefore the cost of feed for 46 cows is 46x
there are 22 pigs, therefore the cost of pig is 22y
46x+22y= 860
representing 2y for x
46(2y)+22y= 860
114y= 860
y= 860/114
y=$ 7.54
recall x=2y
x= 7.54×2= $15.08
therefore $15.08 is spent on a cow in a month

The value of x is 22.5528.
Let ABC be the triangle , <A = 70, <B = 30 ,<C = 80.
Sum of angles in a triangle is 180.
70 + 30 + <C = 180
<C = 180 - 100
<C = 80.
Let sides be a = x , b = 12 and c = ?
According to sines law,
a/sin A = b/sin B = c/sin C
substitute a ,b,A,B values
a/sin A = b/sin B
x/sin 70 = 12/sin 30
x = 0.9397*12/1/2

x = 22.5528.

initially, a $65$-foot ladder rests against a vertical wall such that the top of the ladder is $60$ feet from the ground. then, naoki moves the base of the ladder farther out from the wall so that the top of the ladder slides down until resting against the wall at a point $52$ feet above the ground. given that the wall is perpendicular to the ground, how many feet did naoki move the base of the ladder?
Naoki shifted the base of ladder by 14 feet as the updated distance is 39 feet and old distance was 25 feet.
What is trigonometry?Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six common trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and abbreviations (csc). Finding the elements of vectors, modeling the mechanics of waves (both electromagnetic and physical), summarizing the strength of fields, and using dot and cross products are all physics applications of trigonometry. You can use trigonometry quite a bit in projectile motion.
Here,
The length of ladder= 65 foot
It rest at a wall at height of 60 foot.
So distance of foot of ladder from wall,
=√(65²-60²)
=√625
=25 foot
Now, as the ladder is shifted, it rest on the wall at height of 52 foot.
=√(65²-52²)
=√1521
=39 foot
Shift in the base of ladder,
=39-25
=14 foot
As the updated distance is 39 feet and the previous distance was 25 feet, Naoki moved the base of the ladder up by 14 feet.

2. Solve for the value of x : 2/8 = 3/x+2
thank you! this assignment is graded on accuracy so please try your hardest!!
The slope of the linear equation is 0, and the solution of the second equation is x = 10.
How to find the slope of the line?A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through two points (x1, y1) and (x2, y2), then the slope is:
slope = (y2 - y1)/(x2 - x1)
So if the line passes through (-12, 6) and (4, 6), the slope is:
slope = (6 - 6)/(4 + 12) = 0
The slope is 0.
2) How to solve the equation for x?
Here we have the equation:
2/8 = 3/(x + 2)
If we move the denominators we get:
2*(x + 2) = 3*8

Here in the question given equation ,
x/2 + 1 = √3
To find solution,
we have to subtract 1 from LHS and RHS of equation,
⇒ x/2 + 1 - 1 = √3 - 1
⇒ x/2 = √3 - 1
Next multiply both sides by 2
2( x/2) = 2(√3 -1)

When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood that something will occur by the likelihood that it won't.

Slope:
The slope is found with m = (y2 - y1) / (x2 - x1).
You can use any two points, so I'd pick ones with positive x and y values.
Using (1,5) and (3,3):
m = (3 - 5) / (3 - 1) = (-2)/(2) = -1
The slope is -1.
To find the y-intercept, we can go to the point (-1,7) and use the slope of -1. A slope of -1 means that if x goes up by 1, then then y goes down by 1. So if we go from x=-1 to x=0, then the y-value of 7 will go down by 1.
y-intercept (0,6)
The equation in slope-intercept form is y = -x + 6, since we already found the slope and y-intercept.
