Place the pantomino on 5 numbers they must equal 490 so to check if it would work just add them first if it's not possible explain how it's not possible

Merry is a lab technician with a manufacturer of medical supplies. She is using Boyle's Gas Law to test the pressure inside a sy

BlackZzzverrR [31]

Answer:

The pressure inside the syringe is 1.2 lbs/psi when the volume is 6 cubic centimeters.

Step-by-step explanation:

We are given the following in the question:

When the plunger of a syringe is at a volume of 2 cubic centimeters, the pressure inside the syringe is 0.4 lbs/psi.

Boyle's Gas Law

It states that the pressure of a gas is inversely proportional to volume of gas at a given temperature.

Thus, we can write:

$\dfrac{p_1}{v_1} = \dfrac{p_2}{v_2}$

We have to find the pressure inside the syringe when the volume is 6 cubic centimeters.

Putting values, we get,

$\dfrac{0.4}{2} = \dfrac{p_2}{6}\\\\p_2 = \dfrac{6\times 0.4}{2} = 1.2$

Thus, the pressure inside the syringe is 1.2 lbs/psi when the volume is 6 cubic centimeters.

What is the area of the figure?

finlep [7]

You can divide this image into 2 different shapes and there are multiple ways to do this. I drew a line straight down from the side that has a length of 6 to divide the image into 2 rectangles

I now have a rectangle that has sides of 7 and 10 and a rectangle that has sides of 4 and 8

A=L*W so A=7*10 which is 70
A=L*W so A=4*8 which is 32

add these areas together to get 102 so "C" is the correct answer

Which choice is the solution to the inequality below?

irinina [24]

Option B:

The solution to the given inequality is x ≤ 8.

Solution:

Step 1: Given expression is the inequality.

9x ≤ 72

Step 2: To find the solution to the inequality:

9x ≤ 72

Step 3: Divide by 9 on both sides of the inequality.

$$\frac{9x}{9}\leq \frac{72}{9}$

Step 4: The solution is x ≤ 8

The solution to the given inequality is x ≤ 8.

Hence Option B is the correct answer.
