5 times because 60÷12 = 5
Answer:
It will take 2 hours, 13 minutes and 20 seconds for both pipes to fill the pool.
Step-by-step explanation:
Given that an inlet pipe can fill an empty swimming pool in 5hours, and another inlet pipe can fill the pool in 4hours, to determine how long it will take both pipes to fill the pool, the following calculation must be performed:
1/5 + 1/4 = X
0.20 + 0.25 = X
0.45 = X
9/20 = X
9 = 60
2 = X
120/9 = X
13,333 = X
Therefore, it will take 2 hours, 13 minutes and 20 seconds for both pipes to fill the pool.
Domain is the numbers you can use
you can't use any numbers that make an impossibility like a negative square root or dividing by 0
set the denomenator equal to 0 to find what values of x make it 0
x^3-1=0
add 1 both sides
x^3=1
cube root both sides
x=1
domain is all real numbers except for 1
range is the numbers you get from inputing domaain
there is a vertical assemtote there so all bases are covered
range is how high and low y goes
domain is how far left and right x goes
domain is all real numbers except x=1
range is all real numbers
First, let's solve the inequality:
<span>x - 3 < -9
//add 3 to both sides:
x<-6
the second inequality:
x + 5 ≥ 10</span>
//substract 5 from both sides:
<span>x ≥ 5
So we need to map:
</span>
<span>x<-6
</span><span>x ≥ 5
Now, shading will be to the leftof -6 and to the right of 5 - this is compatible with answers A and B.
A closed circle means that the number is included, so the correct answer is A!</span>
