9. $12,50
10. $17.50 (ripoff lol)
11. Clearly Alastair, they got some strong muscles
12. Taryn would be charging $15 an hour and alastair $24.50 an hour. $735 divided by $15 an hour equals 49 hours for Taryn. $735 divided by $24.50 an hour equals 30 hours for Alastair.
13a. 5 minutes to make a sculpture and 7 balloons in a sculpture
13b. Tomas uses 1.4 balloons a minute
13c. 14 balloons (tip. when multiplying a decimal by 10, 100, etc, just move the decimal for the number of zeroes.) 1.4x10 = 14. Simply move the decimal to the right one because there is one zero in 10.
13c blanks. The first blank is 1.4 and the second blank is 14
14. 8 pound bag of dog food is a way better deal!
15. $10.50
16a. The price for 25 whistles is $0.85 each, 50 whistles for $0.72 each, or 80 whistles for $0.75 each. The difference between the highest number and lowest number is $0.13 or 13 cents.
16b. $0.34 or 34 cents
16c. She should order 80 Kazoos <em>not a meme reference</em>
I hope all of this helped! It took forever!
The correct answer for this question is letter "<span>D. (x) / (sqrt (1+x^2))."

Make a triangle. yes a triangle. label "opposite" side x and adjacent side 1 since the tangent is x = x/1
use pythatoras to find the hypotenuse which will be
square root (1 + x^2)
then
<span>sin(ta<span>n<span>−1</span></span>(x)<span>) = x / (square root (1 + x^2))
</span></span>
that being opposite over hypotenuse
and by the same triangle
<span>cos(ta<span>n<span>−1</span></span>(x)) = </span>x / (square root (1 + x^2))
Answer:

Step-by-step explanation:
Answer:
2 units
Step-by-step explanation:
The length of VW is just the distance between the two coordinates. You could use the distance formula, or an easier and faster way would be to recognize that since both points have the same y-coordinate, the distance between them will just be the distance of the x-coordinates. The absolute value of -4 and -2 is 2, so the length of VW is 2 units.
Hope this helped! ;)
Answer: The mean of the list given is 10.
To find the mean of a list of numbers, first add up all the numbers.
10 + 10 + 11 + 9 = 40
Now, divide the list by the total number of people.
40 / 4 = 10
The mean of this list is 10.
