Answer:

Option A is correct.

A linear pair of angles whose measure sum to 180 degree and share a common ray

Step-by-step explanation:

Linear pair of angles states that it is formed when two lines intersect as shown in the figure given below,

Two angles are said to be linear pair of angles if they are adjacent angles formed by two intersecting lines.

Then, the measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Therefore, A linear pair of angles whose measure sum to 180 degree and share a common ray.

When would you need to use a small standard deviation?

Answer:

You can also use standard deviation to compare two sets of data. For example, a weather reporter is analyzing the high temperature forecasted for two different cities. A low standard deviation would show a reliable weather forecast.

The graphs below have the same shape. Complete the equation of the blue

aleksklad [387]

Answer:

(x+2)^2+1

Step-by-step explanation:

G is shifted 2 to the left and one up. 2 to the left is represented by changing the input by adding 2 to it (as the original is 2 more than the edited), and adding 1 to the end of it adds 1, so our answer is (x+2)^2+1

Emilio writes the inequality 17(f+2)+45.99<200 The situation using the variable as to represent the number of friends solve a

larisa [96]

Answer:

7 friends

Step-by-step explanation:

Given the inequality expression

17(g+2)+45.99<200

We are to find the value of g that satisfies the inequality

Expand

17g+34 +45.99<200

17g+79.99<200

Subtract 79.99 from both sides

17g+79.99-79.99<200-79.99

17g<120.01

g<120.01/17

g<7.059

Hence the max number of friend that can attend is 7friends.

laila [671]

5 roach motels per square yd

A = L * W
A = 7 * 4
A = 21 square yds

so if they set out 5 roach motels per square yd, then they need to set out :
5 * 21 = 105 roach motels <==
