Answer:

Below

Step-by-step explanation:

5^n = 0.2

First write the number in exponential form with the base of 5 :

     5^n = 5^-1

Because the bases are the same, we can set the exponents as equal :

     x = -1

Hope this helps! Best of luck <3

Solve the empty gas tank of a truck needs to be completely filled. the tank is shaped like a cylinder that is 3.5 ft long with a
Dmitrij [34]
5.3 minutes.  
First, let's calculate the volume of the tank. That will be the area of the base multiplied by it's length. And since it's base is a circle, the area is pi*r^2. So:
 V = l*pi*r^2
 V = 3.5 * pi * (2.2/2)^2
 V = 3.5 * pi * (1.1)^2
 V = 3.5 * pi * 1.21
 V = 4.235 * pi
 V = 13.30464489
 
 So the tank has a volume of about 13.3 ft^3. Now simply divide that volume
by the rate of incoming fluid. So
 13.3 / 2.5 = 5.32 
 Rounding to 2 significant figures gives a time of 5.3 minutes.

What is the graph of the solution to the following compound inequality?
ohaa [14]

Answer:

<h2>C.</h2>

Step-by-step explanation:

<, > - open circle

≤, ≥ - solid circle

<, ≤ - draw to the left

>, ≥ - draw to the right

3-x\geq2\qquad\text{subtract 3 from both sides}\\\\-x\geq-1\qquad\text{change the signs}\\\\\boxed{x\leq1}\\\\4x+2\geq10\qquad\text{subtract 2 from both sides}\\\\4x\geq8\qquad\text{divide both sides by 4}\\\\\boxed{x\geq2}

Answer:

A. g=11

Step-by-step explanation:

We want to find which choice makes the equation true. Let's plug in each answer choice.

A. g=11

26=7(11-9)+12      

26= 7(2)+12              Solve inside the parentheses.

26= 14+12                 Multiply 7 and 2.

26= 26                      Add 14 and 12.

This answer must be correct, but let's check the other choices .

B. g=12

26=7(12-9)+12      

26= 7(3)+12              Solve inside the parentheses.

26= 21+12                 Multiply 7 and 3.

26≠33                       Add 14 and 12.

This choice is not correct.

C. g= 13

26=7(13-9)+12      

26= 7(4)+12              Solve inside the parentheses.

26= 28+12                Multiply 7 and 4.

26≠40                      Add 28 and 12.

This is also not correct.

D. g= 14

26=7(14-9)+12      

26= 7(5)+12              Solve inside the parentheses.

26= 35+12                 Multiply 7 and 5.

26≠47                       Add 35 and 12.

This choice is not correct either.

The value of g that make the expression 26=7(g-9)+12 a true statement is A. g=11.
