Answer:
1/6 yard of felt
Step-by-step explanation:
Su Ling started with one yard, and she used 5/6 of it, which means five-sixths of the yard of felt get taken away. Now you have the last sixth of the yard left over - 1/6 of a yard of felt. One equals six sixths, so here's the math -
1yd = 6/6 yd
6/6 yd - 5/6 yd = 1/6 yd
Answer:
π4;3π4
Step-by-step explanation: Trig table gives:
sinx=√22 --> arc x=π4
Unit circle gives another arc x that has the same sin value:
x=π−π4=3π4
Answer:
4 and 5
Step-by-step explanation:
Assuming your 2nd sentence should be: "The sum of the squares of the two numbers is 41"
X + Y = 9 {equation 1}
X² + Y² = 41 {equation 2}
from equation 1: y = 9-x
Substitute that into equation 2
x² + (9-x)² = 41
x² + 81 - 18x + x²= 41
2x² - 18x + 40 = 0
We can factor out a 2
x² - 9x + 20 = 0
(x-5)(x-4) = 0
x = 5 or 4
checking
Your two numbers are 4 and 5
4² + 5²
= 16 + 25
= 41
