Answer:
see below (I hope this helps!)
Step-by-step explanation:
41. √20 = √4 * 5 = √4 * √5 = 2√5
43. The sum of interior angles in a triangle is 180°, therefore, x = 180 - (75 + 64) = 41°.
45. 15 + 5(2x - 3) = 15 + 5(2x) + 5(-3) = 15 + 10x - 15 = 10x
47. Complementary angles have a sum of 90°, therefore, x = 90 - 48 = 42°.

Answer:
522
Step-by-step explanation:
The assumption is that the proportion of tagged fish caught is the same as the proportion of all fish that were caught and tagged:
(all fish)/(number tagged) = (sample size)/(number in sample tagged)
all fish = (number tagged) · (sample size)/(number in sample tagged)
all fish = 174 · 39/13
all fish = 522
If all the assumptions are reasonable, the number of fish in the lake is estimated at 522.
Answer:
There is no answer.
0 is rational since it can be written as a fraction (0/5, 0/69)
1 is obviously rational. 7/8 is .875 and 5 1/4 is 5.25
Answer:
He will have to shovel at least 11 driveways
Step-by-step explanation:
He gets 7$ for each drive way, so if he shovels 10, 10 x 7= 70$, But he still needs 5 more dollars, so he will need to shovel an extra driveway so that he can get 75$ he will have 2$ extra
