You didn't list the options
btw
the next step should be
(add 4 to both sides)
2y = 16
or
2y - 4 + 4 = 12 + 4
Answer:
a) 
b) 
Step-by-step explanation:
<u>Coterminal angles</u> have the same terminal sides in standard position.
a) To find an angle between 
and 
, that is coterminal with 
, we keep adding multiples of until we get an angle within the specified range.
.
In some cases you would have to subtract in order to get the specified angle. That is when the angle given is positive.
b) This time we want to find an that coterminal with radians.
We keep subtracting multiples of 
until we get an angle measure within the specified range.
Answer: 2.325 meters
Step-by-step explanation:
The roof of a lean-to-garden shed has a gradient of 0.35.find the height....they have given the base as 1.5m and a shorter height 1.8m its like a house
-------
It sounds like you have a right triangle with base = 1.5,
----
Use a proportion to get:
(height of that triangle)/1.5 = 35/100
height of that triangle = 1.5*0.35 = 0.5250
-----
greater height of the lean-to = 1.8 + 0.5250 = 2.325 meters
Answer:
[143.61, 156.39]
Step-by-step explanation:
Because the population standard deviation is not available AND the sample size is less than 31, we can use a t procedure here.
Plug these values into your calculator:
Sample mean = 150
Sample size = 16
Standard deviation = 12
Confidence level = 95% = 0.95
and get [143.61, 156.39] as your confidence interval
Answer: 35/4 miles..... (Hopefully I read correctly)
Step-by-step explanation:
(-7/2)-(-49/4)
(-7/2)+49/4
-14/4+49/4
35/4
Hope this helps!
