Angle 2 = 22 degrees (that line is dividing that angle into 1 & 2 equivalently)
Angle 3 = 90 degrees.
Answer:
-1?
Step-by-step explanation:
Answer:
30 each of 23% bars and 18 each of 79% bars
Step-by-step explanation:
If x is the number of 1 kg 23% copper bars, and y is the number of 1 kg 79% copper bars, then:
x + y = 48
0.23x + 0.79y = 0.44(48)
Substituting and solving:
0.23x + 0.79(48-x) = 0.44(48)
0.23x + 37.92 - 0.79x = 21.12
16.8 = 0.56x
x = 30
y = 48 - x
y = 18
You need 30 each of 23% bars and 18 each of 79% bars.
The slope is a 2
here the stpes
6/3 got 2
y2-ya
x2-x1
then you get 6/3 devide ad that you slope
D
You subtract 5 1/4 (5.25) - 3 3/4 (3.75) = 1 1/2 (1.5)
