Answer:
x = 60 degree
Step-by-step explanation:
90 + 90 + 2x - 10 + 2x + 2x + 10 = 540 degree (sum of 5 interior angles)
180 + 6x = 540
6x = 540 - 180
x = 360/6
x = 60 degree
It takes 10 workers 5 days to complete a road repair when working 2 hours a day.
So, this becomes : man hours required to finish the work.
Given is, if 2 people work for 5 hours a day, then let the number of days to finish the road be = d
So, total man hours =
Now, or
Hence, it will take 10 days for 2 people working 5 hours daily, to complete the work.
1 recipe ......2 5/8 = 21/8
1/2.................?
21/8 * 1/2
= 21/16
= 1 5/16
answer is given below
29/6 = 203/42
16/7 = 96/42
to make the denominator 42 we use common tables for this just multiplying .
Question isn't well formatted ;
If the question meant that choosing a marble for five hundred times ; then the calculation is stated below:
Answer:
214
Step-by-step explanation:
Given that :
Probability of picking a red out of a bag of colored marble = 3 : 7 ; that is 3 / 7
P(red) = 3 / 7
If the number of picks (with replacement) = 500
Then, the approximate number of red marbles chosen will be :
P(red) * number of picks
3/7 * 500 = 214.285
Approximate Number of red marbles chosen = 214
