Answer:
80
Step-by-step explanation:
X= 4.167 you cross multiply both the equations. so you get 30x - 50x = 10x - 125. you shift all the values of x on side and then divide it by 125 sso you get x= 4.167
Answer:
The two triangles are related by <u> hypotenuse leg </u>
so the triangles are <u> congruent </u>
======================================================
Explanation:
The square markers indicate we have 90 degree angles. This means the two triangles are right triangles.
The tickmarks tell us which sides correspond and are the same length. The double tickmarked sides are the hypotenuses of each triangle. They are the same length because of the matching tickmarks. The same can be said about the legs marked with single tickmarks.
Based on those tickmarks, and the fact we have right triangles, we can use the <u>hypotenuse leg theorem</u> to prove the <u>triangles are congruent</u>.
The hypotenuse leg theorem only works for right triangles.
Since "hypotenuse leg" is used quite often in geometry, it is abbreviated to "HL".
Answer:
Step-by-step explanation:
(5+3/4+1+1/4)/(2/3)
(7)/(2/3)
7(3/2)
21/2
10+1/2
Ten and one half weeks
The new set of data would be
69, 83, 89, 94, 100 (from least to greatest)
Mean= 87 (You add all of the numbers in the set together, and divide by how many numbers there are)
Median= 89 (the middle number)
Mode= none (There is no number that repeats its self)
Range= 31 (Subtract the greatest number by the smallest number)
Hope this helps!
