What is the equation of the line that passes through the point (2,0) and has a slope of 5/2

Answers

Answer :

y = 5/2x - 5

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5/2 , thus
y = 5/2x + c ← is the partial equation
To find c substitute (2, 0) into the partial equation
0 = 5 + c ⇒ c = 0 - 5
y = 5/2x - 5 ← equation of line

Step-by-step explanation:

Angle on a straight line = 180

106 + ∠st = 180

∠st = 180 - 106 = 74

x = ∠st + 23

= 74 + 23

= 97

Answer:

51 degrees

Step-by-step explanation:

This is a scalene triangle. Which means it sums up to 180 degrees. Therefore, you have to add up all the degrees to 180. 106+23 is 129, and 180 - 129 is 51.

Rick’s scores in his last 15 rounds of golf are 72, 80, 75, 84, 78, 72, 75, 68, 81, 74, 79, 70, 77, 83, and 72. If he scores an 80 on each of the next three rounds, which measure of center would increase more, the mean or median?

Answers

Answer:

The median increased more

Step-by-step explanation:

Given that:

Scores on last 15 :

72, 80, 75, 84, 78, 72, 75, 68, 81, 74, 79, 70, 77, 83, 72

Obtaining the range, mean, median and mode from the data above :

Rearranged data:

68, 70, 72, 72, 72, 74, 75, 75, 77, 78, 79, 80, 81, 83, 84

Range = 84 - 64 = 16

Mode = 72 - frequency of 3)

Mean = ΣX / n where n = sample size

Mean = 1140 / 15 = 76

Median = 0.5(n+1)th term = 0.5(16)th term =

8th term = 75

A score of 80 on each of next 3 rounds :

72, 80, 75, 84, 78, 72, 75, 68, 81, 74, 79, 70, 77, 83, 72, 80, 80, 80

Rearranged data:

68, 70, 72, 72, 72, 74, 75, 75, 77, 78, 79, 80, 80, 80, 80, 81, 83, 84

Range = 84 - 68 = 16

Mean = ΣX / n where n = sample size

Mean = 1380 / 18 = 76.67

Median =0.5(n+1)th term = 0.5(19)th term =

9.5 = (9th term +. 10th term) / 2 = (77 +78) / 2 = 77.5

A chemist has 100 ml of 25% acid solution. how much of the solution does she need to drain and replace with 70% acid solution to obtain 100 ml of 60% acid solution?

Answers

Answer:

The proportion of acid at 70% that the chemist must use will be 77.8%, while the remaining 22.2% will be acid at 25%.

Step-by-step explanation:

Since the chemist has 100 ml of solution with 25% acid, and wants to obtain a solution of 60% acid by mixing the first with another 70% acid solution, to determine how much of each solution the chemical should use necessary to perform the following calculation:

70 x 1 + 25 x 0 = 70

70 x 0.9 + 25 x 0.1 = 65.5

70 x 0.8 + 25 x 0.2 = 61

70 x 0.7 + 25 x 0.3 = 56.5

Therefore, the proportion to be used is between 70% and 80% of acid at 70%, and 20% to 30% of acid at 25%.

70 x 0.75 + 25 x 0.25 = 58.75

70 x 0.76 + 25 x 0.24 = 59.2

70 x 0.77 + 25 x 0.23 = 59.65

70 x 0.78 + 25 x 0.22 = 60.1

Thus, the proportion should be between 77 and 78% of acid at 70% and 22 and 23% of acid at 25%.

70 x 0.778 + 25 x 0.222 = 60.01

Thus, finally, the proportion of acid at 70% that the chemist must use will be 77.8%, while the remaining 22.2% will be acid at 25%.

A store sells shirts at a price of 2 for $5.00. At this price, how much do 7 shirts cost?

Answers

Answer:

$17.50

Step-by-step explanation:

2 goes into 7 3 times, and 5 times 3 is $15.00, so theres one shirt left. If 2 shirts cost $5, one will cost $2.50. So, 15+2.50= $17.50

5/2 equals 2.50 so 2.50x7 equals 17.50

Because theassignment was turned in late, the score was reduced to 20 points.What was the percentage decrease in the score?Symbol requiere this is a trigonometry question . Answer NOW!The day had been one of those unbearable ones, when every sound had set her teeth on edge like chalk creaking on a blackboard, when every word her father or mother said to her or did not say to her seemed an intentional injustice. And of course it would happen, as the end to such a day, that just as the sun went down the back of the mountain and the long twilight began, she noticed that Rollie was not around.Tense with exasperationshe would simply explode if Mother got goingshe began to call him in a carefully casual tone: "Here, Rollie! He-re, boy! Want to go for a walk, Rollie?" Whistling to him cheerfully, her heart full of wrath at the way the world treated her, she made the rounds of his haunts; the corner of the woodshed, where he liked to curl up on the wool of Father's discarded old windbreaker; the hay barn, the cow barn, the sunny spot on the side porchno Rollie.Perhaps he had sneaked upstairs to lie on her bed where he was not supposed to gonot that she would have minded! That rule was a part of Mother's fussiness, part too of Mother's bossiness. It was her bed, wasn't it? But was she allowed the say-so about it? Not on your life. They told her she could have things the way she wanted in her own room, now she was in her teens, buther heart raged against the unfairness as she took the stairs stormily, two steps at a time, her pigtails flopping up and down on her back. If Rollie was on her bed, she was just going to let him stay right there, and Mother could shake her head and mumble all she wanted to. But he was not there. The bedspread and pillow were crumpled, but not from his weight. Earlier that afternoon, she had flung herself down to cry there. And then she couldn't. Every nerve in her had been twanging, but she couldn't cry. She could only lie there, her hands doubled up hard, furious that she had nothing to cry about. Not really. She was too big to cry just over Father's having said to her severely, "I told you if I let you take the chess set you were to put it away when you got through with it. One of the pawns was on the floor of our bedroom this morning. I stepped on it. If I'd had my shoes on, I'd have broken it."Well, he had told her to be sure to put them away. And although she had forgotten and left them, he hadn't forbidden her ever to take the set again. No, the instant she thought about that, she knew she couldn't cry about it. She could be, and she was, in a rage about the way Father kept on talking, long after she'd got his point, "It's not that I care so much about the chess set," he said, just leaning with all his weight on being right, "it's because if you don't learn how to take care of things, you yourself will suffer for it later . . . .
