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!

Find the length of BC
bazaltina [42]

Answer:

BC = 19.78

Step-by-step explanation:

using sin(x) rule

sin(54)= 16/BC

sin(54)=0.80

∴0.80=16/BC  (divied both side by 0.80)

BC=16/0.80 =19.78

If the student is a domain/inout and the hair color is the range/output how is these two set of relation not a function?
IRINA_888 [86]

Answer:

A function is a relation that maps inputs from a set called the domain, into outputs from a set called the range.

Such that each input can be mapped into only one output.

So for example, if we have a relation that maps the input 2 into two different values:

f(2) = 4

f(2) = 8

Then this is not a function.

In the case of the problem, we have a student as the input, and the hair color as the output.

So we will have something like:

f(student) = blond

And if this student decides to change his/her hair color to red?

Then the function becomes:

f(student) = red

So for the same input, we had two different outputs, which means that this is not a function.

We also could have the case where a given student has two colors (Californian for example)

Where again, we would see two different outputs for one single input.
