Using the distance formula, calculate how far Tre threw the ball. (4 points: 2 points for setup, 1 for calculation, 1 for the answer).

Answers

Answer:

[tex]D = 63.717[/tex]

Step-by-step explanation:

The details that complete the question are:

[tex](x_1,y_1) = (0,42.78)[/tex]

and

[tex](x_2,y_1)=(90,42.78)[/tex]

Required

Determine how far the ball travelled

Distance is calculated using:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute values for x's and y's

[tex]D = \sqrt{(42.78 - 0)^2+(42.78-90)^2}[/tex]

[tex]D = \sqrt{42.78^2+(-47.22)^2[/tex]

[tex]D = \sqrt{1830.1284+2229.7284[/tex]

[tex]D = \sqrt{4059.8568[/tex]

[tex]D = 63.717[/tex]

Hence, the ball travelled a distance of 63.717 units

D=63.7170055794

Kenan has $40. He wants to buy a video game for $24 and some candy bars for $1.25 each. How many candy bars can Kenan buy after buying the video game?

Please help me!!

Answers

Answer: 15

Step-by-step explanation:

40- 24 = 16

16 dollars worth of candy

1.25 dollars per candy x 12 candy bars = $15 dollars of candy worth

15 is the closest answer because if u multiply 13 with 1.25 it will be 16.25 which is over the price

Answer:

Step-by-step explanation:

You know he has $40, and you know the game is $24.

Subtract $24 from 40, and you end up with $16.

You have all three angles already, so it's easy: 90°, (4x - 8)°, (6x + 13)°

The sum of all angles is 180°

90 + (4x - 8) + (6x + 13) = 180

I know for me it hasnt been that long ago. But we also like judging pictures too right? Well I bet I can judge a movie clip and a picture and compare the two. I will be comparing a picture of the balcony scene from romeo and juliet and a movie clip of the romeo and juliet balcony scene. I honestly think that the movie clips were more useful The movie clips that were played out from Shakespeare's script were pretty tremendous I must say. The acting was almost like if the story was not written by Shakespeare and instead was recorded by him. But the picture doesn't have Romeo in it. It also doesn't have words so if someone saw it for the first time not knowing that it was Juliet and the balcony scene then they would not think of it as Juliet in the balcony.In other words, the video clip gives you more explanation because there is feeling and changed emotion and there are also words that back up those emotions. On the other hand for the picture, there are only lines and curves and it's just a drawing although it does show a romantic feeling we dont know this for sure but the roses do symbolize Romeo when it comes to the picture.
