A) 15
Step-by-step explanation:
20 x 0.75= 15
Answer:
∠ACB 107°
Step-by-step explanation:
1.) First, by using straight angle theorem we can determine that ∠CED is equal to 180 - 147 which is 33°.
2.) Next, using alternate interior angles theorem we know that ∠CDE = ∠ABC which is 40°
3.) Then, because of the angle sum theorem we know that all the angles of the triangle must add to 180° and we can therefore solve for ∠DCE using the equation 33 + 40 + x = 180 where x is ∠DCE. By solving this we get 107°.
4.) Finally, using vertical angles theorem we know that ∠DCE = ∠ACB and so ∠ACB is 107°
80% of quizzes + 20% of final = final grade
80% * 73 + 20% * x = 70
0.8 * 73 + 0.2x = 70
58.4 + 0.2x = 70
0.2x = 11.6
x = 58
Answer:
4.42857142857 but since we are rounding to the nearest hundredth it would be 4.43
Step-by-step explanation:
You would add all the numbers together (7+4+2+6+4+5+3=31) then you would divide by the number or numbers there is (31 divided by 7= 4.42857142857) then round to the nearest hundredth (4.43000000000 = 4.3)
