13 friends

59-7=52(to find the number of balls that Mike gave to his friends if he gave them only one ball each)

52/4 =13(if 52 is the number of balls that he gave them if he gave them one each, if he gives them four balls each all you have to do is to divide it by 4)

Cos (π/6)I think this one

Answer:

Below in bold.

Step-by-step explanation:

The sine is positive in the first and second quadrants and negative in other 2.

The cosine is positive in the first and 4th quadrants and negative in other 2.

Note that sin(pi/6) = 1/2 and cos(pi/3 = 1/2).

sin(7pi/6) = 1/2  

cos(5pi/3) = 1/2

sin(5pi/6) = 1/2

Answer:

18.90$

Step-by-step explanation:

Pen = p

Notes = n

n = 1.20

5p + 7n = 9p

-9p + 5p + 7n = 0

-4p + 7n = 0

-4p + (7*1.2) = 0

-4p + 8.4 = 0

8.4/4 = p

2.1 = p

9p = 9*2.1

9p = 18.90$

Answer:

0.006

Step-by-step explanation:

The number is currently in scientific notation. To change scientific notation into standard notation move the decimal place equal to the number of the exponent. In this case, the exponent is -3. So, move the decimal place 3 digits. Since the 3 is negative, move the decimal to the left. Therefore, 6.0x10^-3 becomes 0.006 because the decimal was moved 3 places to the left. When moving the decimal fill in any empty spaces with zeros.

AB is not a ray. It has two endpoints.

"It is a part of a line that has a fixed starting point but no end point."

For given example,

We have been given a part of a line AB.

The starting point is A and the end point is B.

We know, one of the end of the ray is denoted by arrow.

Since both the ends of given figure are fixed, it is not ray.

AB is called as line segment.

Therefore, AB is not a ray. It has two endpoints.

Answer:

Dan is correct

Step-by-step explanation:

First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.

Part 1

Answers: point Q, point R, point S

-----------------

Explanation:

All three points mentioned are on the same straight line; hence they are collinear.

=======================================================

Part 2

Answer: Point T or point W

Pick one of those answers only

-----------------

Explanation:

Notice how point W is not on the line shared by points Q, R, and S. The same can be said about point T with that line.

So we would say that the set {T, Q,R,S} is not a collinear set of points. We could also say {W, Q,R,S} is also not collinear.

Answer:

-9

Step-by-step explanation:

x² + 4x - 45

x² + (9x - 5x) - 45

x² + 9x - 5x - 45

x(x + 9) - 5(x + 9)

(x + 9)(x - 5)

x + 9 = 0

x = -9

Answer: -9

Step-by-step explanation:

If 5 is a root of the quadric equation, then

x²+4x-45=0

x²-5x+9x-45=0

x(x-5)+9(x-5)=0

(x-5)(x+9)=0

The other root is -9

Answer:

21/20

Step-by-step explanation:

One way to look at it:

Convert 1.05 to a percentage so it's easier to see it as fraction out of 100

fraction x 100 = %

1.05 x 100 = 105%

105% means 105/100, and reducing the fraction gives 21/20.

21/20 = 1.05

The Probability of picking green chips,  blue chips and red chips respectively are 7/20, 1/5, and 9/20.

Number of green chips = 7

Number of blue chips = 4

Number of red chips = 9

Total number of chips = 7+4+9 = 20

Probability of picking green chips = 7/20

Probability of picking blue chips = 4/20 = 1/5

Probability of picking red chips = 9/20
