The permutation of 6 things taken 4 at a time is 360 So, option C is correct.
What are permutations?The different arrangements which can be made out of a given number of objects by taking out some or all at a time are called permutations.
The permutation of 6 things taken 4 at a time.
It is calculated as follows;
[tex]^6P_ 4[/tex] = 6!/(6-4)! =6!/2!
[tex]^6P_ 4[/tex] = (6×5×4×3×2×1) ÷ (2×1)
[tex]^6P_ 4[/tex] = 720/2 = 360

Slope is 5, and (5,3) is on the line
The equation of the line is y=___
Answers
Answer:
y = 5x - 22
Step-by-step explanation:
In this question, we have to find the equation of the line.
We know that the slope is 5 and passes through (5, 3) on the graph.
We know that our equation must be in slope-intercept form: y = mx + b
To find our y-intercept, or "b", we would plug in our given information and solve for b.
Solve for b:
3 = 5(5) + b
3 = 25 + b
Subtract 25 from both sides.
-22 = b
This means that our y-intercept is -22. We can now make our equation with our new information:
y = 5x - 22
The equation of the line is y = 5x - 22

Answers
Answer:
4200 m²
Step-by-step explanation:
The drawing below (not to scale) shows a running track. The ends are semicircles. The distance between the two inner parallel straight lines is 60 meters, and they are each 100 meters long. The track is 10 meters wide. Find the area of the track. Shaded part
Solution:
The big semicircle has a diameter = 60 m + 10 m + 10 m = 80 m
The radius of the big semicircle = 80 m / 2 = 40 m
The area of the two big semicircles at both end of the big track = 2 * (1/2 πr²) = πr² = π(40)² = 5027 m²
The big track has semicircles at both ends and a rectangle. The length of the rectangle = 100 m, the width of the rectangle = diameter of big semicircle = 80 m
Area of big rectangle = length * width = 100 m * 80 m = 8000 m²
Area of big track = 8000 m² + 5027 m² = 13027 m²
The small semicircle has a diameter = 60 m
The radius of the small semicircle = 60 m / 2 = 30 m
The area of the two small semicircles at both end of the small track = 2 * (1/2 πr²) = πr² = π(30)² = 2827 m²
The small track has semicircles at both ends and a rectangle. The length of the rectangle = 100 m, the width of the rectangle = diameter of small semicircle = 60 m
Area of small rectangle = length * width = 100 m * 60 m = 6000 m²
Area of small track = 6000 m² + 2827 m² = 8827 m²
The area of track (shaded part) = Area of big track - Area of small track = 13027 m² - 8827 m² = 4200 m²

Solve the system by substitution:
y = -3x + 10
y=-3x + 4
Please show the steps!
Answers
Answer:
x=1, y=7
Step-by-step explanation:
y = -3x + 10 - first equation
y=-3x + 4 - second equation
rearrange the expression to
-3x-y= -10
3x-y= -4
pick an equation and simplify; lets pick the second equation
3x-y= -4
[tex]\frac{3x}{3} = \frac{-4+y}{3}[/tex]
divide 3 by both sides
x= [tex]\frac{-4+y}{3}[/tex] - third equation
substitute the value of x into an equation; lets pick the first equation
-3x-y= -10
-3[tex](\frac{-4+y}{3})[/tex]- y = -10
simplify. -3 cancels 3 so we are left with
-1(-4+y)-y = -10
simplify
4-y-y= -10
4-2y= -10
subtract 4 from both sides
-2y= -10-4
-2y= -14
divide -2 by both sides
y=7
substitute the value of y, (y=7) in an equation, we are using the second equation
3x-y= -4
3x-7= -4
3x = -4+7
3x= 3
divide 3 by both sides
x=1
so the answer is x=1, y=7
