Choose all of the statements that are true about AABC.

Answers

Answer:

Step-by-step explanation:

sin(62°) = 25/BA

BA = 25/sin(62°) ≈ 28.3

Angle BAC = 180°-90°-62° = 28°

BC = √((BA)^2-(AC)^2) = 13.3

cosC = 0

Answer:

A and D are correct

Step-by-step explanation:

Given ΔABC

∠C = 90°∠B = 62°AC = 25

The options:

A. 25/BA = sin 62° ⇒ BA = 25/sin 62° = 28.3 ≈ 28

Correct

B. ∠BAC = 90° - 62°= 28° ≠ 48°

Incorrect

C. 25/BC = tan 62° ⇒ BC = 25/tan 62° = 13.29 ≠ 18

Incorrect

D. cos(∠ACB) = 0 ⇒ cos 90° = 0

Correct

7:8

Answer:

7 : 8

Step-by-step explanation:

Total number of adults in the survey = 150

Number of women = 80

Number of men = 150 - 80

                           = 70

Ratio of men : women = 70 : 80

                                     = 70 /80

                                     = 7 / 8

                                     = 7 : 8

What is the tone of this excerpt from Mark Twain's "Mental Telegraphy Again"? I have three or four curious incidents to tell about.

Several years ago I made a campaign on the platform with Mr. George W. Cable. In Montreal we were honored with a reception. It began at two in the afternoon in a long drawing-room in the Windsor Hotel. Mr. Cable and I stood at one end of this room, and the ladies and gentlemen entered it at the other end, crossed it at that end, then came up the long left-hand side, shook hands with us, said a word or two, and passed on, in the usual way.

Exercise 1 Read the passage. Based on what you already know, underline the verbs.The Marshmallow ExperimentImagine that you are seven years old. You are participating in an experiment. A researcher greets you and shows you into a small room. In the room there is a marshmallow. The marshmallow is for you, but here is the interesting part: The researcher tells you that he is going to leave you alone in the room for a while. You can eat the marshmallow right away, or you can wait until he gets back. If you wait until he gets back, you will get a second marshmallow.What do you do? Do you eat the marshmallow right away?An experiment like this, known informally as the marshmallow experiment, was conducted decades ago at Stanford University. It turned out that some children ate the marshmallow right away, while others were able to wait. In other words, some sought instant self-gratification, and some delayed it.Years later, the researchers followed up on the participants. They found that the children who delayed self-gratification were in general more successful than those who ate the marshmallow right away. By a variety of measures, including SAT scores, they appeared to be more competent.Common sense tells us that the ability to delay self-gratification is a mark of maturity. The marshmallow experiment provides evidence that it may also correlate with success in life.Notes:- Many of these verb phrases consist of an auxiliary verb and a main verb. So, for example, are participating and do...eat are considered verb phrases.- is going to leave: If we consder is going to a kind of auxiliary verb, then this is a verb phrase, just like will leave.- known as...: If you underlined known, thats fine.

Exercise 2 Underline the complete subjects in the sentences below, and double- underline the verbs that go with them. Identifying the subject means identifying the main word of the subject and the parts that modify it. (In the first sentence, the main word is in boldface.) When you underline the verb, include both auxiliary verbs and main verbs (as in the first sentence, with was...used).In the 1960s and 70s, the term generation gap was often used to refer to the differences between young people in the U.S. and their parents generation. Many young people felt distant from their parents because of differences in ideas about politics, social issues, and popular culture. Since then, conflicts between generations have diminished in many ways. Child-rearing experts in the late 20th century encouraged parents to be like friends to their children.
