I don't know if I am right but I think this is the answer:
If we write beaker with x and content with y
then y=56.8/2=28.4 this is the content of one beaker
so there are two beakers:
2x+28.4=180.4
2x=180.4-28.4
2x=152/2
x=76
Answer:
From my research, the coordinate points can be found on image below. Since N is the reflection of B and O is the reflection of C, if we were to draw a line to the right of N and a vertical line below C, the point of intersection of these two lines should give us the location of point O. Doing just that, point O is found at (5,5).

Answer:
B
Step-by-step explanation:
The term in the () is usually the x coordinate, and the last term (-1) is usually the y coordinate.
Answer:
Approximately 143 mL of 1:4 solution and 457 mL of water
Step-by-step explanation:
A 1:4 solution has a concentration of 1/(1+4) = 1/5 or 20%.
Similarly, a 1:20 solution has a concentration of 1/(1+20) = 1/21 or 4.76%.
If x is the mL of 20% solution and y is the mL of water, then:
x + y = 600
1/5 x = 1/21 (600)
Solve:
x = 5/21 (600)
x ≈ 143
y ≈ 457
You need approximately 143 mL of 1:4 solution and 457 mL of water.
Answer:
"35.84 years" is the appropriate solution.
Step-by-step explanation:
The given values are:
Rate of savings generation,
System cost to install,
= $30000
Now,
The total savings will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
When,
Savings = 0
t = 0, then
⇒ 
⇒ 
The formula will be:
⇒ ![s(t)=6000[e^{\frac{t}{20} }-1]](https://tex.z-dn.net/?f=s%28t%29%3D6000%5Be%5E%7B%5Cfrac%7Bt%7D%7B20%7D%20%7D-1%5D)
On putting the values in the above formula, we get
⇒ 
On taking log, we get
⇒
