Answer:
B) ΔCAT is congruent to ΔDOG
Step-by-step explanation:
If angles are congruent, the triangles are <em>similar</em>. When both corresponding angles and corresponding sides are congruent, the triangles are <em>congruent</em>.
ΔCAT is congruent to ΔDOG
I'm sorry, but I have to seriously question the whole process.
-- What does "the angle between the Earth and sun" mean?
-- How in the world does he measure the distance between the Earth and sun ?
-- How are either of these related to the distance between the Moon and Sun ?
To me, this "scientist's" methods are as defective as this question is.

replace x and y by their value 1 and 3
3 = 4(1) - 1 = 4-1 = 3
2(1) + 3 = 2 + 3 = 5
correct
<u>M</u><u>e</u><u>t</u><u>h</u><u>o</u><u>d</u><u> </u><u>2</u><u> </u><u>:</u>
y = 4x - 1
2x + y = 5
y = 4x - 1
y = -2x + 5
y - y = 4x - 1 - ( -2x + 5 )
0 = 4x - 1 + 2x - 5
6x - 6 = 0
6x = 6
x = 6/6 = 1
y = 4x - 1
y = 4(1) - 1
y = 3
correct
Answer:
-2
Step-by-step explanation:
5 - 1 = 4
-3 - (-5) = -2
4/-2 is simplified to 2/-1, which is then rewritten as -2
Here are the steps to answer this question:
1. Find the denominator. Since there is 8 possible outcomes, our denominator will be 8.
2. Find the numerator. To do this we need to find out of all the 8 possible outcomes, how many are them are y. Since its only 1 y, the numerator will be 1.
3. Now all we have to do now is make our fraction. The 8 possible outcomes given, only one of them has y which means that our fraction will be 1/8.
4. Answer: 1/8 or .125 or 12.5% chance for the spinner to land on y. I hope this helps!
