Substitute teachers with Greenwood School District get paid by the day, although subs with teaching credentials earn a different

amount than subs without credentials. Yesterday, 10 non-credentialed subs (x) and 10 credentialed subs (y) taught in the district. That cost the district $1,560. Today, 3 non-credentialed subs and 10 credentialed subs taught, receiving $1,077 from the district.
Choose the correct system of equation.

A.{10x+10y=15603x+10y=1077
B.{20x+13y=1560x+y=1077
C.{10x+3y=107710x+10y=1560

Find the common ratio for the following sequence .1, .01, .001
morpeh [17]

Answer:

0.1

Step-by-step explanation:

The <em>common ratio</em> of a sequence is the number you multiply one term to get the next one. Here, we multiply 0.1 by 0.1 to get 0.01, and 0.01 by 0.1 to get 0.001, so our common ratio is 0.1.

AleksandrR [38]

Answer:

MN = 2.8 units

Step-by-step explanation:

By the property of isosceles trapezoid,

1). Bases are parallel.

2). Base angles of an isosceles trapezoid are congruent.

2). Opposite sides of the congruent angles are congruent.

By third property,

Measure of side KL = Measure of side MN

2.8 = Measure of side MN

Another way to find the length of MN is,

Distance between M and N = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

MN = \sqrt{(3-1)^2+(0+2)^2} = \sqrt{8}

MN = 2.8 units

Therefore, MN = 2.8 will be the answer.
