Answer:
26+c
Step-by-step explanation:
Answer:
square root of 65
Step-by-step explanation:
all i am going to say is, Pythagorean theorem.
Y=mx+b
m=slope=-34
b=y-intercept=6
y=-34x+6 is your linear equation
To solve this problem, let us first assign variables. Let
us say that:
x = volume of 67% herbicide solution
y = volume of 46% herbicide solution
The total volume should be 42 liters therefore:
x + y = 42
x = 42 – y --> 1
The component mass balance on the pure herbicide would
be:
0.67 x + 0.46 y = 0.55 (42) --> 2
Substituting equation 1 to 2:
0.67 (42 – y) + 0.46 y = 23.1
28.14 – 0.67 y + 0.46 y = 23.1
- 0.21 y = - 5.04
y = 24 L
Calculating for x using equation 1:
x = 42 – 24
x = 18 L
Therefore we only need 18 L of the 67% herbicide
solution.
Answer:
A. 18 L
By looking at the diagram, we see that angle C is 45 degrees, angle A is 90 degrees, and angle B is unknown
Given that the sum of all the triangle's angle is 180 degrees, angle B is also 45 degrees
This means that we have a 45-45-90 triangle, which has some special properties as shown in the diagram I uploaded.
Thus <u>BC in the simplest term is </u>
Hope that helps!
