Longest side must be smaller than the sum of other two smaller sides, so
only 2nd option fits best

In short, Your Answer would be Option B

Hope this helps!

So bascically what you would do is you would do A^2+B^2=C^2 for every single one of them to find which one best fits the equation 6 squared +8 squared =15 squared 36+64=225 so that would be 100 which does not equal 225 therefore A is not the answer. 9 squared+ 13 squared= 17 squared 81+169= 289 250 does not equal 289 so therefore B is not the answer. 2 squared + 3 squared= 6 squared. 4+9=36. 13 does not equal 36 so therefore C is not the answer but because there are no more answers D is left by process of elimination

Answer:

The average speed of the car, in miles per hour, from 17:30 to 19:42, is 119.167 meters per second.

Step-by-step explanation:

Physically speaking, average speed ( $\bar v$ ), measured in miles per hour, is the distance travelled ( $\Delta s$ ), measured in miles, divided by time ( $\Delta t$ ), measured in hours. That is:

$\bar v = \frac{\Delta s}{\Delta t}$ (1)

The time needed by the vehicle is:

$\Delta t = 72\,min\times \frac{1\,h}{60\,min}$

$\Delta t = 1.2\,h$

If we know that $\Delta s = 143\,mi$ and $\Delta t = 1.2\,h$ , then the average velocity of the car is:

$\bar v = \frac{143\,mi}{1.2\,h}$

$\bar v = 119.167\,\frac{m}{s}$

The average speed of the car, in miles per hour, from 17:30 to 19:42, is 119.167 meters per second.

a coin must have diameter of 27.13 millimeters.To the nearest hundredth, what is the circumference of this coin millimeters

Bas_tet [7]

To find the circumference, you will use the formula for finding circumference of a circle.

I used the true value of pi for the calculations.

C = pi x d
pi x 27.13
C = 85.77mm

Which point is part of the solution of the inequality y 2 12x – 11.

Papessa [141]

Answer:

Point (0,0)

Step-by-step explanation:

Given the inequality y > 12x – 11.

We will check which of the given options will be applied for the inequality

A) (1,0)

Substitute with x = 1 and y = 0

0 > 12*1 - 11

0 > 1 ⇒ Wrong

So, Point (1,0) is not part of the solution of the inequality.

B) (3,2)

Substitute with x = 3 and y = 2

2 > 12*3 - 11

0 > 25 ⇒ Wrong

So, Point (3,2) is not part of the solution of the inequality.

C) (1,1)

Substitute with x = 1 and y = 1

1 > 12*1 - 11

1 > 1 ⇒ Wrong

So, Point (1,1) is not part of the solution of the inequality.

D) (0,0)

Substitute with x = 1 and y = 0

0 > 12*0 - 11

0 > -11 ⇒ True

So, Point (0,0) is part of the solution of the inequality.

Also, see the attached figure which represents the given inequality

The shaded area represents the solution of the inequality, and we can note that point (0,0) is part of the solution of the inequality
