Distance Between 2 Points = sqr root [(X2 -X1)^2 +(Y2 -Y1)^2]

Distance Between 2 Points = sqr root [(2 -1)^2 + (4--2)^2]

Distance Between 2 Points = sqr root [1 + 36]

Distance Between 2 Points = sqr root [ 37 ]

Distance Between 2 Points = 6.082762530298219

Two basketball teams, the Tigers and the Bears, played several games. The Tigers won the first game by two points. The total num

aleksandrvk [35]

Answer: Tigers = 46 Bears = 44

<u>Step-by-step explanation:</u>

Let x represent the numbers of points scored by the Bears.

then x + 2 is the number of points scored by the Tigers.

Bears + Tigers = Total

x + x + 2 = 90

2x + 2 = 90

2x = 88

x = 44

Bears (x) = 44

Tigers (x + 2) = 44 + 2 = 46

If the product of a number and negative 5−5 is subtracted from the number, the result is 44 more than the number. Find the numb

fomenos

Answer:

8.8 or 8(4/5) or 44/5

Step-by-step explanation:

x-(-5x) = x+44

6x= x+44

5x=44

x=44/5 = 8.8

8.8-(-5*8.8) =8.8+44

8.8+44 = 8.8+44

For three visits, the electrician earned $40 × 3 = $120 in "per-visit" charges. For working x hours, he earned 20x in "per-hour" charges. The total of these came to 50x:

120 +20x = 50x

120 = 30x . . . . . . . . subtract 20x

4 = x . . . . . . . . . . . . . divide by 30

The electrician worked 4 hours that day.

This is a combination problem requiring a combination solution with the following formula and steps:

C (n, r) =? C (n, r) = ?

n choose r

n (objects) = 16

r (sample) = 5

C (n, r) =? C (n, r) = ?

C (n, r) =C (14,5) C (n, r) =C (16,5)

=16! (5! (16−5)!) =16! (5! (16−5)!)

= 4368
