Answer:
t2 = 52.8 hours
it will take 52.8 hours if its flow is reduced to 5 litres per minute.
Step-by-step explanation:
The volume of the swimming pool can be written as;
Volume V = flow rate × time
V = R×t
V = R1×t1 = R2×t2
R1×t1 = R2×t2
t2 = R1×t1/R2 ........1
Given;
Flow rate R1 = 12 litres per minute
Flow rate R2 = 5 litres per minute
time t1 = 22 hours
Substituting the given values into equation 1;
t2 = R1×t1/R2 = 12×22/5
t2 = 52.8 hours
it will take 52.8 hours if its flow is reduced to 5 litres per minute.
Answer:
The solution is x = 1/log(6)
Step-by-step explanation:
Hi there!
First, let´s write the equation:
6ˣ + 2 = 12
subtract 2 at both sides of the equation
6ˣ = 10
apply log at both sides of the equation
log(6ˣ) = log(10) log(10) = 1
Apply logarithm property: log(xᵃ) = a log(x)
x log(6) = 1
Divide both sides by log(6)
x = 1/log(6)
The solution is x = 1/log(6)
Have a nice day!
A. Rectangle and D. Square:::::: thats what I came up with
Parallelograms and Rhombuses have supplementary angles
Answer:
y = -2x + 10
Step-by-step explanation:
The equation is y = mx + b
1. Find the slope first.
--> (y2 - y1) / (x2 - x1) = slope
--> (-12 - -6) / (11 - 8) = (-6) / (3) = -2
2. Then, find the y-intercept (b) by plugging one of the points
--> y = -2x + b
--> -6 = -2(8) + b
--> -6 = -16 + b
--> b = 10
3. Combine
--> y = -2x + 10
