Answer:
Regina writes the expression y +9.3/4
Using The commutative property
a + b = b + a
= 9.3/4 + y
= (9.3/4) + y
Step-by-step explanation:
Regina writes the expression y +9.3/4
Using The commutative property
a + b = b + a
= 9.1/4 + y
= (9.1/4) + y
Answer:
20
Step-by-step explanation:
sin(28) sin(x)
---------- = -----------
7 5
sin(28)* 5 = 7sin(x)
---------------------------
7
sin(28) * 5
---------------- = sin(x)
7
You have to seperate sin from (x). When you do that, it becomes inverse (sin^-1).
sin(28) * 5
sin^-1 (------------------) = x
7
Imput that into you calculator, and you should get 19.59302173 (20 to the nearest degree)
Hope this helps.
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.
