Answer:
20.6 cm (im pretty sure lol)
Step-by-step explanation:
sine rule:
(ab = x)
13.5/sin41 = x/sin90
13.5sin90/sin41 = x
x = 20.57741667
ab = 20.6cm
Answer:
$86
Step-by-step explanation:
You multiply 21.50 times 4
Answer:
= - 
Step-by-step explanation:
Given
= 
( cross- multiply )
2(a - b) = 3(a + 2b) ← distribute parenthesis on both sides )
2a - 2b = 3a + 6b ( subtract 3a from both sides )
- a - 2b = 6b ( add 2b to both sides )
- a = 8b ( divide both sides by 8 )
- a = b ( divide both sides by a )
- =
B. The sample is likely to represent one portion of the population.
This is impossible to say because it's random.
Answer:
You would divide 1442 by 77 Giving you C=18.7
Hope this helped ^^
If not sorry ¯\_(ツ)_/¯
