2/3*5/5 - 3/5*3/3

= 1/15

X = 15°

Given that the angle with m < 165° and m< x° are supplementary angles whose sum add up to 180°,

We can add their sum by establishing the following formula:

m < 165° + x° = 180°
Subtract m< 165° from both sides

m < 165° — m < 165° + x° = 180° — m < 165°

x° = 180° — m < 165°

x° = 15°

Therefore, the value of x = 15 °

A volunteer at the zoo is responsible for feeding the animals in 15 exhibits in the reptile house.

We have to determine how many exhibits are in the reptile house.

Therefore we have

if 15 exhibits = 20% of total exhibits,

What is the percentage?

A percentage is a number or ratio expressed as a fraction of 100.

then 15/20% = 75 total exhibits in the reptile house

We can check the answer,

75 x 20% = 15

Therefore the 75 exhibits are in the reptile house.

After two semesters of course work, a student has completed 32 credit hours of course work with a grade point average of 3.15. What grade point average will the
student need to complete in order to raise their cumulative grade point average to 3.2, if the student is taking 14 credit hours of graded course work this semester
(third semester)?

Answers

Using weighed average, it is found that the student will need a GPA of 3.31.

To find a weighed average, each value is multiplied by it's weight.

For the student's average, we have that:

GPA of 3.15 with a weight of 32.GPA of x with a weight of 14.

We want the mean to be 3.2, thus:

[tex]\frac{3.15(32) + 14x}{32 + 14} = 3.2[/tex]

[tex]3.15(32) + 14x = 46(3.2)[/tex]

[tex]14x = 46(3.2) - 32(3.15)[/tex]

[tex]14x = 46.4[/tex]

[tex]x = \frac{46.4}{14}[/tex]

[tex]x = 3.31[/tex]

The student will need a GPA of 3.31.

He did not look at Prissy, nor did she wish him a happy New Years she would not have dared. Uncle Richard had not been on speaking terms with her or her father, his only brother, for eight years.(2) [While in the store, Prissy overhears her uncle Richard explain that he is on his way to a neighboring town, Navarre, and that he has no one to make his New Year's dinner. Prissy decides to go to his house, make a surprise dinner for him, and leave before he returns. She acts on her plan, cooking a dinner at his house. As she prepares to dish it out, she suddenly hears a voice behind her.](3) Well, well, what does this mean?(4) Prissy whirled around as if she had been shot, and there stood Uncle Richard in the woodshed door!(5) Poor Prissy! She could not have looked or felt more guilty if Uncle Richard had caught her robbing his desk. She did not drop the turnips for a wonder; but she was too confused to set them down, so she stood there holding them, her face crimson, her heart thumping, and a horrible choking in her throat.(6) "I I came up to cook your dinner for you, Uncle Richard," she stammered. "I heard you say in the store that Mrs. Janeway had gone home and that you had nobody to cook your New Year's dinner for you. So I thought I'd come and do it, but I meant to slip away before you came home."(7) Poor Prissy felt that she would never get to the end of her explanation. Would Uncle Richard be angry? Would he order her from the house?(8) "It was very kind of you," said Uncle Richard dryly. "It's a wonder your father let you come."(9) "Father was not home, but I am sure he would not have prevented me if he had been. Father has no hard feelings against you, Uncle Richard."(10) "Humph!" said Uncle Richard. "Well, since you've cooked the dinner you must stop and help me eat it. It smells good, I must say. Mrs. Janeway always burns pork when she roasts it. Sit down, Prissy. I'm hungry."(11) They sat down. Prissy felt quite giddy and breathless, and could hardly eat for excitement; but Uncle Richard had evidently brought home a good appetite from Navarre, and he did full justice to his New Year's dinner. He talked to Prissy too, quite kindly and politely, and when the meal was over he said slowly:(12) "I'm much obliged to you, Prissy, and I don't mind owning to you that I'm sorry for my share in the quarrel, and have wanted for a long time to be friends with your father again, but I was too ashamed and proud to make the first advance. You can tell him so for me, if you like. And if he's willing to let bygones be bygones, tell him I'd like him to come up here with you tonight when he gets home and spend the evening with me."(13) "Oh, he will come, I know!" cried Prissy joyfully. "He has felt so badly about not being friendly with you, Uncle Richard. I'm as glad as can be."(14) Prissy ran impulsively around the table and kissed Uncle Richard. He looked up at his tall, girlish niece with a smile of pleasure.(15) "You're a good girl, Prissy, and a kind-hearted one too, or you'd never have come up here to cook a dinner for a crabbed old uncle who deserved to eat cold dinners for his stubbornness. It made me cross today when folks wished me a happy New Year. It seemed like mockery when I hadn't a soul belonging to me to make it happy. But it has brought me happiness already, and I believe it will be a happy year all the way through."(16) "Indeed it will!" laughed Prissy. "I'm so happy now I could sing. I believe it was an inspiration my idea of coming up here to cook your dinner for you."(17) "You must promise to come and cook my New Year's dinner for me every New Year we live near enough together," said Uncle Richard.(18) And Prissy promised.Describe the storys resolution.
