Answer:
121/14 or 8 9/14
Step-by-step explanation:
The quotient of 1/8 and 1/4 is ...
(1/8)/(1/4) = (1/8)(4/1) = 4/8 = 1/2
The product of 2 2/3 and 3 3/7 is ...
(2 2/3)(3 3/7) = (8/3)(24/7) = (8·24)/(3·7) = 64/7
Subtracting the first result from the second gives ...
64/7 -1/2 = (128 -7)/14 = 121/14 = 8 9/14
_____
<em>Additional comment</em>
When subtracting fractions with denominators that have no common factors, I find it useful to make use of the formula ...
In this case, that gives us (64·2 -7·1)/(7·2) = (128 -7)/14.
Answer:
6 x 10^26
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
I need help myself lol XD
Recall that sin(theta) = opposite / hypotenuse (soh cah toa!)
I will use x for theta.
Sin(x) = 7.78/23.9
x = sin^-1(7.78/23.9)
x = 18.99726...
x = 18.99
Answer:
Bailey's balance after 180 days is $ 157.39.
Step-by-step explanation:
Since Bailey wanted a new pair of shoes, and she put the $ 142 cost on her credit card, but because Bailey has been irresponsible with her credit, the credit card company charges her 22% annual interest, for figure Bailey's balance after 180 days, assuming she made no payments, the following calculation must be made:
365 = 100
180 = X
180 x 100/365 = X
18,000 / 365 = X
49.31 = X
22 x 0.4931 = 10.84
142 x 1.1084 = X
157.39 = X
Thus, Bailey's balance after 180 days is $ 157.39.
