Let's assume, for simplicity, that there were 100 questions in the test: a score of 80% means you got 80 right and (100-80)=20 wrong.
The ratio is then 80 to 20 or
80:20.
you can also simplyfy it, by dividing both numbers by 20:
4:1
which I think is the best way to give the answer!
Answer:
t = 4.5
Step-by-step explanation:
1.8 = 0.4(t) solve for t
Problem 11
Answer: Angle C and angle F
Explanation: Angle C and the 80 degree angle are vertical angles. Vertical angles are always congruent. Angle F is equal to angle C because they are alternate interior angles.
============================================
Problem 12
Answer: 100 degrees
Explanation: Solve the equation E+F = 180, where F = 80 found earlier above. You should get E = 100.
============================================
Problem 13
Answer: 80 degrees
Explanation: This was mentioned earlier in problem 11.
============================================
Problem 14
Answers: complement = 50, supplement = 140
Explanation: Complementary angles always add to 90. Supplementary angles always add to 180. An example of supplementary angles are angles E and F forming a straight line angle.
The answer is 460
1. 23 ones is the same as 23
2. 2 tens is the same as 20
3. 23 ones x 2 tens is the same as 23
x20
