Answer:
a=50 degrees
Step-by-step explanation:
Look at the triangle in the middle. You can find two missing angles to calculate the third one.
50 and 130 are supplementary, so 50 must be the upper right angle. The angle opposite to 80 has to be equal to it, of the upper left angle is 80.
A triangle is 180 degrees total, and 180-(50+80)= 50.
The missing angle for the triangle is 50, and since "a" is opposite to it, the values are equal.
a=50 degrees
Step-by-step explanation:
Scale factor is found by making a fraction of two numbers;
In this case, 3.5/2, since the dilated line is larger
Scale factor: 1.75 (simplified)
Given that QYprime is 4.125,
4.125 * (2/3.5)
= 2.357 (rounded)
Answer:
C
Step-by-step explanation:
On the top there are 4 x and 1 one.
On the left, there are 2 x and 3 one.
You put those together and you get (4x+1)(2x+3), which is C.

6.3120000 × 10^7 I’m pretty sure that the correct answer
Data on first test: 50, 50, 50, 50, 50
Mean = 250 / 5 = 50
In the next test, Data is: 50, 50, 50, 50, 100
Mean = sum of data / number of data
Mean = 50 + 50 + 50 + 50 + 100 / 5
M = 300 / 5
M = 60
In short, Your Answer would be 60
If You're looking for combined progress (average of class then, it would be: 50 + 60 /2 = 110/2 = 55
Hope this helps!
