Answer:

2 or 12

Step-by-step explanation:

The answer that we will use this equation 1/t1 +1/t2=1/ttotal

where t1 is the time of smaller pipe while t2 is the of the larger pipe

Given t total =4 while t2 is equal to t2=t1-6

So know you can solve the problem by changing it into (2t1-6)/(t1*(t1-6))=1/4

8( t1-3)=(t1^2-6t1)

t1^2-14t1+24=0

t1=2 or 12

The depth of water in a tank that’s in the shape of a rectangular prism is inversely proportional to the area of its base if the
ivanzaharov [21]

Answer:

A.  

If the depth is 8 feet, the area of the base is 300 square feet. And if the area of the base is 600 square feet, the depth of the water is 4 feet.

Step-by-step explanation:

Depth = Volume/Area

d = V/A

12 = V/200

V = 12 × 200

    = 2,400

When d = 8, A = 300

V = dA

  = 8 × 300

  =  2,400

When d = 4, A = 600

V = 4 × 600

    = 2,400.

The first option is correct.

I need help ASAP! picture below is what I need​

Answer:

Evaluating the piecewise function when X =3, we get f(3) = 7

Step-by-step explanation:

Given the following piecewise function

f(x)= { 2x+1; where x > 0

         -3 when x ≤ 0

Evaluate the function when X = 3

We will evaluate f(x) =2x+1 where x > 0, because x = 3 and 3 <0

We can't use -3, because x ≤ 0, and 3 is not less than 0.

Now, evaluating the function:

f(x)=2x+1\\Put\:x=3\\f(3)=2(3)+1\\f(3)=6+1\\f(3)=7

So, Evaluating the piecewise function when X =3, we get f(3) = 7

Solve for b.<br><br> b+(−1.9)=−3.7<br><br> Enter your answer in the box
Luda [366]

Answer:

  • b = -1.8

Step-by-step Solution:

<u>Subtract or add to obtain your answer.</u>

  • b + (−1.9) = −3.7
  • => b - 1.9 = -3.7
  • => b = -3.7 + 1.9
  • => b = -1.8

Hence, the value of b is -1.8
