how many different ways could first, second, and third place finishers occur in a race with six runners competing?

Answers

Answer 1

Answer:

720

Step-by-step explanation:

This is a permutation since the order at which the people are picked matter due to the fact that it is a race. Using the permutation formula

P= n!/ (n-r)! you can find the different ways the race would end. n stands for the total number of objects in the set while r stands for the number of objects chosen from said set. Then you plug in the numbers in the formula: P= 10!/(10-3)!= 720

Answer 2
720 hope it help :)

11. 35 ft²

12. 24 cm²

13. 18 ft²

14. 28 in²

15. 9 in²

Step-by-step explanation:

11. A= (b×h)÷2

= (10×7)÷2

= 70 ÷ 2

= 35 ft²

12. A= (b×h)÷2

= (8×6)÷2

= 48 ÷ 2

= 24 cm²

13. A=(b×h)÷2

=(9×4)÷2

= 36 ÷ 2

= 18 ft²

14. A=(b×h)÷2

=(7×8)÷2

= 56 ÷ 2

= 28 in²

15. A=(b×h)÷2

=(3×6)÷2

= 18 ÷ 2

= 9 in²

Write an equation in slope-intercept form for a line with a slope of -2 and a 8 points
y-intercept of 7. *

Answers

Answer:

y=-2x+7

Step-by-step explanation:

slope intercept form is equal to y=mx+c

where y is the y value

x is the x value

m is the gradient

and c is the y intercept

so the equation for this set of values is equal to

y=-2x+7

slope will be the m

and b is the y intercept

y=mx+b

y=-2x+7

Help please this is geometry

Answers

Answer:

14

Step-by-step explanation:

All of the angles are marked as congruent, which means it is an equlateral triangle. This means that all of the sides are congruent too.

Therefore z + 2 = 2z -10

add 10 to each side

z + 12 = 2z

subtract z from each side

12=z

now that we know that, we can plug it back in to either line (it doesn't matter because they're congruent)

line AB is z+2 which is 12+2 or 14

and line CB is 2z-10 which is 2(12)-10 or 24-10 which is also 14

so line CA is also 14 units long.

If the volume of a cone with the same height as a cylinder equals the volume of the cylinder, the equation for the radius of cone Rin terms of the radius of cylinder r is: ​

Answers

Answer: R = √(3*r^2)

Step-by-step explanation:

For a cylinder with radius r and height H, the volume is:

V = pi*r^2*H

For a cone of height H, and with a base of radius R, the volume is:

V = (1/3)*pi*R^2*H

In this case, we know that both figures have the same height, and the same volume, then we can write:

pi*r^2*H = (1/3)*pi*R^2*H

Now we can divide by pi in both sides to get:

(pi*r^2*H)/pi = ((1/3)*pi*R^2*H)/pi

r^2*H = (1/3)*R^2*H

Now we can divide both sides by H:

(r^2*H)/H = ((1/3)*R^2*H)/H

r^2 = (1/3)*R^2

Now we want to write R in terms of r.

Then we need to isolate R in the above equation:

r^2 = (1/3)*R^2

3*r^2 = R^2

√(3*r^2) = R

R = √(3*r^2)
