Answer:
C
Step-by-step explanation:
sin(theta)=7/8, theta=arcsin(7/8)=61
I only go to the second place behind the decimal. The square root of 63 is 7.93. look at the hundredths place ( the second number behind the decimal) 3 is lower then 4. So four or less let it rest. So leave the 9 a 9. The simplified is 7.9
Answer:
$32.07
Step-by-step explanation:
I am not sure - are we seeing the full information about this problem ?
because the problem description is strangely vague and confusing, as it uses "total cost" two times for not the same thing ...
either total cost means including tax or not including tax. but it cannot mean both ...
I think the most likely understanding of this problem is that the first price is without tax, and now we need to calculate and add the extra 6% tax to get the really total price to be paid.
I will solve this now based on this assumption.
100% = $30.25
1% = 100%/100 = 30.25/100 = $0.3025
6% = 6×1% = 6×0.3025 = $1.815 ≈ $1.82
the total price is then calculated either by
100% + 6%
or by
106% = 100%×1.06 = 30.25×1.06 = $32.065 ≈ $32.07
in both cases we get the same result, of course.
Add $20 and $60 and your answer which is $80 dividdd that by 1.
Answer:
a) 2891.012 
b) 0.496 
Step-by-step explanation:
We know 1 US gallon = 3.79 L
Also
1L =61.024
and given 1 cubit - 18 in
a) gas tank = 12.5 Us gal. = 12.5×3.79 = 47.375L=47.375×61.024= 2891.012
b) as 1 cubit =18 inches
or
18 inches = 1 cubit
==> 1 inch = 1/18 cubit =0. 055555556 cubit
Taking cube on both sides;
==>
×0.055555556×0.055555556=0.000171468
so size of gas tank = 2891.012×0.000171468=0.495715375=0.496
