As far as I know, it is like this: it does not mean that this is an additional test or not; Which part is the additional test is usually not known Since it is not scored, it must be okay to do it badly, a few points need to be explained: the additional test is usually divided into verbal and quantitative (quantitative) additional test, which additional test will only depend on what the first part after you finish writing the composition The first part is Chinese, then you must be a Chinese additional test, and the order of your section is:

Chinese-Mathematics-Chinese-Mathematics-Chinese Note: At present, according to a large number of statistics, it is generally a language test, and there are usually only a few times a year for mathematics to take a special test, so the landlord can default to the additional test for the language test, and the usual practice can also follow this model. There must be three sections, although the additional test part is not scored, but you don't know which section is the additional test, so you have to take each section seriously

Question 1 Option A, if all 8 members of the first committee are members of the second committee, and 10 members of the second committee are members of the third committee, then the three committees together are only 13 people, but not less.

For example, a person's income was originally 100, first rose by 10% and then decreased by 10%, then the final income will not be 100, the denominator of the 10% increase is the original number 100, and the denominator of the 10% decline is the number 110 before the decline, so that his income becomes 99.

The area of the whole circle is ·6 square = 36, and the central angle of the two shaded parts is 160°, that is, the total central angle is 320°, so the area of the non-shaded part is 36 (360°-320°) 360°=4, so the correct answer to this question is d.

Why don't you draw figure1, I thought about it for a long time.

Calculate directly with a calculator, and keep two significant digits in the original formula).

Select A

The primitive majority is simplified towards this kind of thinking.

A $15,000 loan has an interest rate of 8%. Interest is compounded quarterly. If I pay in equal monthly instalments over a period of 3 years, how much is the total amount paid?

1) According to the answer to the question, the corresponding compound interest is calculated, that is, the principal and interest are paid in one lump sum at the end of the period

8% is the annual interest rate, which is the interest rate of 3 months (quarters), 4 of 4*3) is 4 quarters in a year, and 3 is 3 years.

2) However, if the interest is paid in full every month, the principal and the interest of the last month at the end of the period should be:

One month interest = 15000 * 8% 12 = 100, 3 years interest = 100 * 12 * 3 = 3600

Interest + principal = 3600 + 15000 = 18600

This question, if I understand it correctly, should be a mixed interest rate calculation problem. Note that the interest is compounded quarterly, which means that the profit is compounded once in one quarter, and there are a total of 12 quarters in three years, and each quarter is calculated as simple interest, which means that the total repayment amount of the first quarter must be found first, and then superimposed on the next quarter, and so on. Hope it helps.

The first should be profitable, and the second should be quarterly

The specific calculation is as follows: 15000*(1+.)

what is the maximum number of cubes (with sides of a length )that could fit inside a cube (with sides of length 2s ) The answer should be 8

Simth got an 8 percent cost of living raise of $20 per week Explained:Got a 8 percent raise :

It means that the amount a salary is increased; "he got a 3% raise"; he got a wage hike"That is, his salary has increased by 3 percent, and he has gotten an 8 percent cost of living raise, which means that the cost of living has increased by 8 percent every month

It seems that the question is incomplete, 20 is the increase in the cost of living for Beiyou, how much is the salary that I can't get, it may be that I translated it wrongly, if it is simth got an 8 percent raise of $20 per week, then the answer is 270 The previous salary x is x=250 Now the salary is 250+20=270 Ask the master Answer.
