c) Combine 2+3 to get 5. 100-(5x5) equals 100-25. 100-25 is 75. The answer is 75.
d) Combine 2+3 to get 5. Combine 1+4 to get 5, which is 25. The answer is 5.
g) Combine 4+6 to get 10. Combine 70+-6 to get 64. Take the root of 64, leaving you with 10-8. Combine 10 + -8 to get 2. The answer is 2.
h) Combine 5+4 to get 9. Take the root of 36, leaving you with 18 + 6. Combine 18 + 6 to get 24. The answer is 24.
5. [15 + 22 + 53] divided by [12 + 18] = [90] divided by [30] = 3 ribbons each.
6. (4 x 12) + (6 x 8) = 96 total.
Step-by-step explanation:
yes
There are 120 ways to color the 4 rectangles
<h3>How to determine the number of ways?</h3>
The given parameters are:
Paints, n = 5
Rectangles, = 4
The number of ways to color the rectangles is
![Ways = ^nP_r](https://tex.z-dn.net/?f=Ways%20%3D%20%5EnP_r)
This gives
![Ways = ^5P_4](https://tex.z-dn.net/?f=Ways%20%3D%20%5E5P_4)
Apply the permutation formula
![Ways = \frac{5!}{1!}](https://tex.z-dn.net/?f=Ways%20%3D%20%5Cfrac%7B5%21%7D%7B1%21%7D)
Evaluate the expression
Ways = 120
Hence, there are 120 ways to color the 4 rectangles

Well let's say you have a coordinate (2, -1)
Now if we reflect it upon the y-axis we'll end up at the coordinate (2,1)
We see that the x value is still the same.
Answer:
Step-by-step explanation:
![\sin \: 30 \degree = \frac{ \sqrt{5} }{x} \\ \\ \frac{1}{2} = \frac{ \sqrt{5} }{x} \\ \\x = 2 \sqrt{5}](https://tex.z-dn.net/?f=%20%5Csin%20%5C%3A%2030%20%5Cdegree%20%3D%20%20%5Cfrac%7B%20%5Csqrt%7B5%7D%20%7D%7Bx%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B1%7D%7B2%7D%20%3D%20%20%5Cfrac%7B%20%5Csqrt%7B5%7D%20%7D%7Bx%7D%20%20%5C%5C%20%20%5C%5Cx%20%3D%202%20%5Csqrt%7B5%7D%20)
