According to your verbal statement, you are dividing 13 into 9164. You must
write this division as 9164/13, not as 13/9164.
13/9164 returns the result 0.00142 on my phone calculator. That's not what you want. On the other hand, 9164/13 returns the result 704.9.
The result you obtained is probably due to a very small arithmetic error.
Try writing out the problem again, as long division, and doing it again without reference to your first attempt.

Answer:
<em> 5 1/2 weeks </em>
Step-by-step explanation:
Given
Time it will take to complete the building = 85 1/4 hrs
Time he works on the house weekly = 15 1/2 hours
This can be expressed as
1 week = 15 1/2 hours
To calculate the number of weeks it will take to complete the house, we will say:
x = 85 1/4
Cross multiply
15 1/2 x = 85 1/4
31/2 x = 341/4
31x/2 = 341/4
Cross multiply again
31x * 4 = 2 * 341
124x = 682
x = 682/124
x = 5.5weeks
<em>Hence it will take Ryan 5 1/2 weeks to complete the house</em>.
Answer:
1. 31.14
2. 46
Step-by-step explanation:
1. Using order of operations, we first simplify what's in the parentheses, so we do 4.1-(-6.2), or 4.1+6.2. This gives us -5+3.8(10.3). Next is multiplication, so we do 3.8(10.3), which gets us to -5+39.14. Lastly, we add, to get 31.14.
2. First, we solve in the parentheses. Within the parentheses, we do multiplication first, so we first do 3*-2, to get us 8-4(-6+(-13))÷2. Then, we solve inside the parentheses, so we do -6+(-13), to get 8-4(-19) ÷2.
Next, since multiplication and division are on the same level, we go from left to right, so we do -4*-19 first, to get 8+76÷2. Now we do division, to get 8+38. Lastly, we add, to get 46.
I’m not quite sure what the function is but if it’s sine the period is pi/8
