Step-by-step explanation:
please the information needed is up the paper. you took a picture of no. 2 instead of no. 1

therefore, sin(x) = cos(90° - x).
Answer:
y-11
Step-by-step explanation:
First you divide 3 by 3 to get one. Then you add 12 to -1 to get 11. Then you will have y-11. PEMDAS saves lives.
Answer:
Step-by-step explanation:
(-3,-3) ; (8,-3)
![Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-3-[-3]}{8-[-3]}\\\\=\frac{-3+3}{8+3}\\\\=0](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B-3-%5B-3%5D%7D%7B8-%5B-3%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B-3%2B3%7D%7B8%2B3%7D%5C%5C%5C%5C%3D0)
Slope = 0. so, the line is parallel to x-axis
Answer:
1) $283.50
2) 65.21 meters.
Step-by-step explanation:
Part 1)
We know that a spool of ribbon holds 6.75 meters.
A craft club buys 21 spools.
So, the total length of ribbon bought is:

Each meter costs $2. So, the total cost will be:

Part 2)
A spool holds 6.75 meters.
We bought 21 of them, so that total length we have is 141.75 meters.
The club used 76.54 meters.
So, the amount of ribbon that is left is represented by:

Subtract:

So, 65.21 meters of ribbon will be left.
