Letty has 75%
Step-by-step explanation:
15/20 is the same as 75/100 ( 15/20·5) so she has a 75% grade
<span>The perimeter is 14.47
Since you have 3 vertices, the polygon you have is a triangle. The sides of the triangle will be XY, XZ, and YZ. Just use the pythagorean theorem to calculate the length of each side and then add the lengths together for the result.
Side XY = sqrt( (-1-3)^2 + (3-0)^2) = sqrt(16+9) = sqrt(25) = 5
Side XZ = sqrt ( (-1-(-1))^2 + (3-(-2))^2) = sqrt(0+25) = sqrt(25) = 5
Side YZ = sqrt( (3-(-1))^2 + (0-(-2))^2) = sqrt(16 + 4) = sqrt(20) = 4.47
Now add the length of each side together
5 + 5 + 4.47 = 14.47</span>
Answer:
0.125, 0.25, 0.4, 0.666...
Harley, Olga, Kayla, Karla
Step-by-step explanation:
Change each number into a decimal, then compare them.
Karla saved 2/3 = 0.666...
Olga saved 25% = 0.25
Harley saved 1/8 = 0.125
Kayla saved 0.40 = 0.4
From least to greatest:
0.125, 0.25, 0.4, 0.666...
