  1. Answer: Approximately 146 minutes (or if you need the simplified version the answer is 2 hours and 26 minutes).  Step-by-step explanation: Step 1. Two classes of 21 students. To calculate that you would multiply 21 by 2. 21*2=42 Step 2. So now we know you need 42 individual pictures. If they each take 3 minutes to take you need to multiply 42 by 3. 42*3=126. So now you know it’ll take 126 minutes to take all the individual pictures. Step 3. Now, there are 2 classes of people and it takes 10 minutes to take each class picture. So do calculate that you need to multiply 10 by 2. 10*2=20. So it’ll take 20 minutes to take both class pictures. Step 4. Now we know it’ll take 126 minutes to take all the individual photos and 20 minutes to take the class photos. Now to calculate the total amount of time it’ll take to take all the photos you need to add 20 to 126.  126+20=146. So, it’ll take 146 minutes to take all the photos. Step 5. (You can skip this step if no simplification is needed in your problem) So, we all know there is 60 minutes in an hour so we’ll divide 146 by 60. 146/60=2.43. So, now we know it’ll take 2.43 hours to take all the photos. 2.43 hours is 2 hours and 26 minutes.  I hope this helps!

Find the smallest solution to the equation 2/3 X² equals 24
iren [92.7K]

Answer:

The smallest solution is -6

Step-by-step explanation:

2/3 x^2 = 24

Multiply each side by 3/2

3/2 *2/3 x^2 = 24*3/2

x^2 = 36

Take the square root of each side

sqrt(x^2) = sqrt(36)

x = ±6

The smallest solution is -6

The largest solution is 6

What is a reasonable constraint for the model -3.2 2.62 -3.2 0
alexandr402 [8]

Answer:

The answer to your question is C. 3.2

Step-by-step explanation:

 | 3.2 |

lines |  |  mean absolute value, and absolute value means the distance of a number to the origin (0,0) it does not matter the sign.

Then to answer your question just do not write the |  |  and consider it as a positive sign.

If your question had a negative number  ex. | -3.2 | the answer would also be 3.2.

A circle has a circumfernce of 6. It has an arc length of 1
fomenos

Answer:

The circumference formula for a circle is C=πd where C is the circumference, d is the diameter of the circle and π is a constant. If you plug in 6 for C and solve the equation for d like:

6= πd and then divide both sides of the equation by π you get that d = 1.90

To find the central angle of an arc you would use the equation S = rθ where S is the length of the arc, r is the radius of the circle, and θ is the measure of the angle which in this case is unknown. So with S = 1 and r = d/2 = 1.90/2 = 0.9549 you would have an equation that looks like this:

1 = 0.9549θ.  

If you divide both sides of the equation by 0.9549 you get θ = 1.047197 radians.  

The question asked for the angle measure in degrees so you would need to convert the angle measure to degrees by multiplying the degree measurement by 180/π

1.047197 x 180/π =  60°
