Answer:

B)Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90 clockwise

Step-by-step explanation:

This is because, to locate a point rotated by 90° from point A, we first draw a circle with the origin as its center and a radius of the origin and point A. We then locate a point on the line that is 90° clockwise from point A. For a 90° clockwise rotation, for a given pair of coordinates, (x,y), the resulting pair of coordinates is (y,-x). So, for the coordinates (1,4), the resulting coordinates we are looking for is (4, -1), which is the point rotated 90° clockwise from point A. The point is thus (4,-1).

A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associ

g100num [7]

Answer: the system of equations that could be used are

700x + 1700y = 21200

y = x + 4

Step-by-step explanation:

Let x represent the number of associates assigned to the case.

Let y represent the number of partners assigned to the case.

The daily rate charged to the client for each associate is $700 and the daily rate for each partner is $1700.

The law firm was able to charge the client $21200 per day for these lawyers' services. This mean that

700x + 1700y = 21200 - - - - - - - - - - 1

The law firm assigned 4 more partners than associates to the case. This means that

y = x + 4 - - - - - - - - - - - - - - - - -2

In a given course a student receives preliminary examination grades of 81, 85, and 95. The final examination is weighed for one-

Vsevolod [243]

Answer:

B. 96

Step-by-step explanation:

Let x represent score of final third exam.

We have been given that in a given course a student receives preliminary examination grades of 81, 85, and 95.

Let us find average of preliminary scores.

$\frac{81+85+95}{3}=\frac{261}{3}=87$

We have been given that the final examination is weighed for one-third and the average of the preliminary grades is weighed as 2/3 of the final grade. This means that final grade is equally weighed into 3 parts. The two parts are 87 each and third part is x.

Using our given information, we can set an equation as:

$\frac{87+87+x}{3}=90$
