PLEASE HELP WILL MARK BRAINLIEST

Answer:

74046

Step-by-step explanation:

Permutations = [tex]_np_r=\frac{n!}{(n-r)!}[/tex]

where r = choice of things from a set ( in this case the 3 places ) so r = 3

and n = amount of things ( in this case the 43 people ) so n = 43

We then plug in the values of n and r in the permutations formula

[tex]\frac{43!}{(43-3)!} =74046[/tex]

Hence the answer is 74046

Answer:

volume = 24,501.42

Step-by-step explanation: the way i did it:

first find the radius, 34 divided by 2 = 17π

then multiply the radius by itself 17 x 17 = 289

after, multiply 289 by 27 to get 7,803

then multiply 7803 by 3.14 to get 24,501.42

Hope this is correct!

(p.s.) if you do it on a calculator and use the pi symbol (π) the answer would be 24,513.84

Answer:

0.2985

Step-by-step explanation:

find cot0 given cos0=2/7 and the terminal side is in quadrant IV

Given

cos theta  = 2/7

theta = arccos(2/7)

theta = 73.40 degrees

cot theta = cot73.40

cot73.40 = 1/tan73.40

cot73.40 = 1/3.35

cot73.40 = 0.2985

hence the required answer is 0.2985

theyre equal to the ones across from them, and i used a line to find the measure of d

Answer:

which one

Step-by-step explanation:

the upper answer would be 38 and lower would be

Answer:

4f = 38

Step-by-step explanation:

f(x) = 9x + 2

=

f(4) = 9(4) + 2

=

4f = 36 + 2

=

4f = 38

Answer:

width = 5 in

length = 17 in

Step-by-step explanation:

Area of a rectangle = length x width

width = w

length = 2 + 3w

85 = (w) x (2 + 3w)

85 = 2w + 3w³

this can be solved using quadratic equation

3w³ + 2w - 85 = 0

factors of 3w³ x -85 that add up to 2w are : +17 w and -15w

(3w³ - 15w) (17w - 85) = 0

3w(w - 5) 17(w - 5) 0

w = 5

or w = - 17/3

the width cannot be a negative number. the correct width is 5 in

Length = 2 x 3(5) = 17 inches

Answer: -4

Step-by-step explanation:

2(-3)*2-(-3)+5= -4

Answer:

A = 135 sq in

Step-by-step explanation:

Area of parallelogram is base x height

A = 15(9)

A = 135 sq in

Answer:

x = 14/5

Step-by-step explanation:

2x-4= -x-6/2

multiply by 2 on both sides to get rid of the fraction

4x-8= -x-6

add both sides by 8 and both sides by x to get the constants on the right and the variables on the left

4x+x=6+8

combine like terms/simplify

5x=14

divide both sides by 5 to isolate the x

x=14/5

i hope this helps :)

Answer:

it is A becuase it passes through 0,0 and 5,5 the rest either pass through 5,5 but not 0,0 and B doesnt pass thorugh 5,5 but does pass thorugh 0,0 so its A

Step-by-step explanation:

Step-by-step explanation:

It is Graph B. We can do this by checking the points. The equation given is d = 5t^2, where d technically is the y-coordinate and t is the x-coordinate. On Graph B, two obvious points are (1, 5) and (2, 20). We can check these points to see if they fit the equation.

(1,5): d = 5t^2

5 = 5(1)^2

5 = 5*1

5 = 5, so this point is correct.

(2, 20): = d = 5t^2

20 = 5(2)^2

20 = 5*4

20 = 20, so this point is correct.

We know that Graph A is incorrect because it doesn't follow the equation. The line goes through (1, 5), which we already know is correct, (2, 10), (3, 15), and (4, 20). We already figured out that (2, 20) is correct so (2,10) can't be correct. (3, 15) and (4, 20) are also incorrect but in this case, we only need to find one incorrect coordinate to validate our answer. Thus, as Graph A is wrong, Graph B is right.

Answer:

1.5 hour

Step-by-step explanation:

You divide 6 by 4.

Answer:

7.2 hrs

Step-by-step explanation:

Jack does 4/5 of the work in 6 hrs. He still needs to do 1/5 more if he's doing it by himself. 1/5 of 6 = 1.2 and 1.2 + 6 = 7.2 hrs

Answer:

the second one

Step-by-step explanation:

They make it all so complicated with all of the complex lines doing their own thing, though this is somewhat straight forward once you see it.

With the Domain, these are the x values that the line covers.

For this, it would be -5 ≤ x ≤ 4, because all of the x values are between these two values.

With the Range, these are the y values that the line covers.

For this, it would be -4 ≤ x ≤ 5, because all of the y values are between these two values.

With the X-Intercepts, these are the x values the line crosses for when the y value is 0.

For this, it would be -3 and -1.

With the max, it is the highest point within a graph, for where the y value is the greatest.

For this, it would be x = 4 at the coordinate (4, 5).

Answer:

7/10 or 70% or 0.7

Step-by-step explanation:

4 black, 10 red

10+4=14

now you put it over the total marbles

14/20=7/10

i don't know how your teacher wants you to give the answer but it is 7/10 or 0.7 or 70%

Answer:

14.25

Step-by-step explanation:

So, lets go over our information.

We have a price of 15 dollars.

And it is 5% cheaper.

This means that the price is 95% of what it used to be.

We must find 95% of 15.

We know that to put 95% into decimal form, we must divide by 100:

95/100

=

0.95

So we know we must multiply 15 by 0.95:

15x0.95

=

14.25

So our price is now 14.25 dollars

hope this helps! :)
