A total of 22 dimes and nickels have a value of $1.90. If d represents the number of dimes and n represents the number of nickel

s, which system of equations models this situation?
A.

d + n = 1.9
0.1d + 0.05n = 22

B.

d + n = 22
0.1d + 0.05n = 1.9

C.

d + n = 1.9
0.1d + 0.5n = 22

D.

d + n = 22
0.1d + 0.5n = 1.9

Answer:

Answer: d + n = 22 and 0.1 d + 0.05n = 1.9 Step-by-step explanation: Let d be the number of dimes and n the number of nickels. Total dimes = 22 Therefore, d + n = 22 1 dime = 10 cents = 0.1 1 nickel = 5 cents = 0.05 Value of 22 dimes = $ 1.90 So , 0.1d + 0.05n = 1.9 Therefore, d + n 22 and 0.1d + 0.05n = 1.9 models the given% D% 3D situation.

What is the image of point (4, 5) after a counterclockwise rotation of 270º about the origin?
andriy [413]
A <span>counterclockwise rotation of 270º about the origin is equivalent to a </span><span>clockwise rotation of 90º about the origin.

Given a point (4, 5), the x-value, i.e. 4 and the y-value, i.e. 5 are positive, hence the point is in the 1st quadrant of the xy-plane.

A clockwise rotation of </span><span>90º about the origin of a point in the first quadrant of the xy-plane will have its image in the fourth quadrant of the xy-plane. Thus the x-value of the image remains positive but the y-value of the image changes to negative.
Also the x-value and the y-value of the original figure is interchanged.
For example, given a point (a, b) in the first quadrant of the xy-plane, </span><span>a counterclockwise rotation of 270º about the origin which is equivalent to a <span>clockwise rotation of 90º about the origin will result in an image with the coordinate of (b, -a)</span>

Therefore, a </span><span>counterclockwise rotation of 270º about the origin </span><span>of the point (4, 5) will result in an image with the coordinate of (5, -4)</span> (option C)
