Answer:
40615
Step-by-step explanation:
Note, rounding off decimals involves observing if the said decimal is up to the value of 5. If it is, then it can be rounded up, if not, its rounded off.
Since we need to round the numbers to the second decimal before performing the operation, we will have, 8123÷0.2
Note, 8123 has no decimal so we ignore
But 0.211 has a second decimal which is the first 1 so because it's not up to 5, we round it off to 0.
Hence we have 8123 ÷ 0.2= 40615.0
Since our answer has no decimal, we leave it like that.
Answer:
hopefully tht example will help u
Step-by-step explanation:
To change 0.0002 to scientific notation, move the decimal to the right 4 places so that you get 2. The exponent on the base 10 will be -4 because the decimal was moved to the right 4 places. So 0.0002 in scientific notation is 2×10−4.
I think its 3/6 * 78 time = 39
Answer : 39 times
Hopefully it’s correct :)

Answer:
Theta = 0, 60 degrees.
Step-by-step explanation:
2 sin^2 theta + 3 cos theta = 3
Using the identity sin ^2 theta = 1 - cos^2 theta :
2(1 - cos^2 theta) + 3 cos theta = 3
2 - 2cos^2 theta) + 3 cos theta = 3
2 cos^2 theta - 3 cos theta + 3 - 2 = 0
2 cos^2 theta - 3 cos theta + 1 = 0
(2 cos theta - 1)(cos theta - 1) = 0
cos theta = 1/2 , cos theta = 1
Theta = 60 degrees or theta = 0
