Percentage means 'out of 100 100 '. Convert the decimal number to a fraction by shifting the decimal point in both the numerator and denominator. Since there is 1 1 number to the right of the decimal point, move the decimal point 1 1 place to the right.
Answer:
$6.36 with taxes or $6 without tax
Step-by-step explanation:
$22.90/3.6 = $6.36 per pound with taxes
$21.60 /3.6 = $6 per pound
<span>If x represent the number of nickels in the box and y represent the number of dimes in the box (note that x>0 and y>0), then the total value of x nickels is $5x and total value of y dimes is $10y. Adding these amounts of money you get that in money box was $</span><span><span>(5x+10y)</span>.</span>
<span> Sally knows that she has less than $20 in the box, then 5x+10y<2000 ($20=2000 cents).
</span>
Since this inequality is strict, then you should draw the dashed line 5x+10y=2000. The line divides coordinate plane into two parts.
Pick point (0,0) and consider to which part this point belongs. Since 5·0+10·0<2000, you can conclude that (0,0) is a solution of given inequality and belongs to needed part. Hence you should take the shaded part below the line for positive values of x and y.
Among the statements, this is the true one.
∠BCO is complementary to ∠BOC
ΔBCO is a right triangle. B is 90°.
Interior angles of a triangle = 180°. With B as 90°, the remaining angles, C and O, must total 90°. Thus they are complementary.
Answer: 5
Step-by-step explanation:
We know that the standard deviation of the sampling distribution of the means is given by :_
Given : The average weekly earnings for employees in general automotive repair shops is
.
The standard deviation for the weekly earnings for such employees =
Now, the standard deviation of the sampling distribution of the means of average weekly earnings for samples of size
:-
Hence, the standard deviation of the sampling distribution of the means of average weekly earnings for samples of size 100 = 5
