Answer:

60 people

Step-by-step explanation: Multiply 20 by 3 and you will get 60, which is the total combonation of people.

Answer:

6840 I think.

Step-by-step explanation:

There's 20 people in the race, it's asking for how many possibilities there are for each person to end up as 1st, 2nd, & 3rd.

Problems like these are solved by 20! (20x19x18xetc till 1) over (the number of competitors (20) minus the number of prized places (3)). 20-3=17.

20! over 17!.

Sorry if it's wrong but it's how I remember it to be.

Answer: i dont know

have a good day!

Step-by-step explanation:

bye

Answer:

The answer is 5/10 multiply 1/2 by 5

4 hours for 18

7 hours for 25.50

Difference in hours: 7-4 = 3

Difference in cost: 25.50 - 18 = 7.50

7.50 / 3 = 2.50

A. They charge 2.50 per hour.

B. 2.50 x 4 = 10

18 - 10 = 8

The flat fee is 8 dollars

C. 8 + (2 x 2.50) = 13 dollars

Step-by-step explanation:

On simplifying its

M2 + 10m - 56 = 0.......... (divide both side by 3)

M2 - 4m + 14m - 56=0

M(M-4) + 14(m-4) =0

(M+14) + (m-4)=0

M =4, - 14.

If the condition is given that you cannot put m's value negative. Than the answer is M=5....

THANKU

Answer:

m = 4

m = -14

Step-by-step explanation:

here's your solution

=> 3m^2 + 30m - 168

=> firstly we will make it in simplest form

=> take 3 common

=> 3(m^2 + 10m - 56)

=> we get , (m^2 + 10m - 56)

=> now, factories it by using middle term split

=> m^2 + 14m - 4m - 56

=> now take common

=> m(m + 14) - 4(m + 14)

=> (m - 4) (m + 14)

=> m - 4 = 0

=> m= 4

=> (m+14) =0

=> m = -14

Answer:

B

Step-by-step explanation:

Hey There!

they are asking for the equation in slope intercept form

Slope intercept form is y=mx+b

where m equals slope and b equals y intercept

to find the slope we do change in y over chang in x

as y goes up 2 x goes down 5 so the slope would be -2/5

the y intercept is at (0,4) so the y intercept is 4

now we add everything together and get that the equation in slope intercept form is

y=-2/5x+4

so we can conclude that the answer is B

Answer:

Step-by-step explanation:

A line can be expressed as

y=mx+b, where m is the slope and b is the y intercept (the value of y when x=0)

Any two points form a line when connected.

m=(y2-y1)/(x2-x1), in this case we have points (0,4) and (5,2) so

m=(2-4)/(5-0)

m=-2/5 so our line is now

y=-2x/5+b, using (5,2) we can solve for b

2=-2(5)/5+b

2=-2+b

b=4, so the line is

y=-2x/5+4

Answer B

Answer:

y= 500+7x

Step-by-step explanation:

Given data

Total amount for the rent=  $500

Cost of food per night= $10

Family charges per night=$60

Let the number of nights be x

and let the total charges be y

Hence, the expression for the situation is given as

y=500+10x+60x

y= 500+7x

Answer:

  C +2D = 3s -21

Step-by-step explanation:

Use the substitution property of equality.

  C = s -5

  D = s -8

Then the value of your expression is ...

  C +2D = (s -5) +2(s -8)

  = s -5 +2s -16

  C +2D = 3s -21

Answer: 240

Step-by-step explanation:

2x36)/2=36

(36+39)x2/2=75

(31+39)x2/2=70

(14+31)x2/2=45

(2x14)/2=14

14+45+70+75+36=240

I hope this helps :)

Answer:

Part A; Initial dosage is 10 milligrams

Part B:

8.4113 milligrams after 1 hour

5.0057 milligrams after 4 hours.

Step-by-step explanation:

It is given M(h)= 10 [tex]e^{-0.173h}[/tex]

Initial dosage is the 10 milligrams

After 1 hour, plug in h as 1

So, M(1)=10[tex]e^{-0.173*1}[/tex]

Simplify the right side

M(1)=10(0.84113)

M(1)= 8.4113 milligrams.

Now, after 4 hours

M(4)=10 [tex]e^{-0.173*4}[/tex]

M(4)=10(0.50057)

M(4) =5.0057 milligrams

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

The two triangles shown are similar (AAA: they share the angle on the right and the two other angles are corresponding and therefore equal).

Since, they're similar, the sides are in ratio to eachother:

[tex]\frac{x+(x+3)}{8+12} = \frac{x+3}{12}[/tex]

12(2x+3)=20(x+3)

24x+36=20x+60

4x=24

x=6

Answer:

The real solutions are : -6, -3 and 2

Step-by-step explanation:

The solutions of a functions are the input values at an output zero

Graphical wise, this can be represented by the order pairs (x, 0)

In other words, these are the points that lie on the x-axis

Examining the given graph, we can see that the points lying on the x-axis are:

(-6, 0), (-3, 0) and (2, 0)

This means that:

The real solutions of the function are:

-6, -3 and 2

Answer:

  91 rad/s

Step-by-step explanation:

The relationship between angular velocity (ω) and constant angular acceleration (ω') is ...

  ω(t) = ω0 + t·ω'

  ω(0.25) = 95 = ω0 + 0.25(16)

  95 -4 = ω0 = 91 . . . rad/s

The initial angular speed was 91 radians per second.

Answer:

how many floors the elevator goes down per unit of time

Step-by-step explanation:

not sure what the unit of time is but its seconds or minutes im pretty sure it doesnt say

Answer:

The elevator started at floor 7

Step-by-step explanation:

The y-intercept is when x is 0

In this situation x represents time, so when no time has passes yet y is at 7

This means that the elevator was at floor before any time passed (before it started moving)

hope this helps, lmk if it doesnt :)
