Which set represents a pythagorean triple (1 point)?

Vinil7 [7]

A pythagorean triple is A squared + B squared = C squared. A and B being the smaller numbers (side lengths) whilst C is the larger number (diagonal). Any two numbers (sides) that added together after each being squared equals the bigger number (diagonal) squared is a pythagorean triple.

2 1/3 −1.5x=12.3 please help me I'm really struggling need an answer ASAP.

Harrizon [31]

Answer:

-6.64

Step-by-step explanation:

since you need to find the value of x , but all values to one side and have x on the other .. meaning :

2 1/3 -12.3 = 1.5x

now that you have this find the decimal value of 2 1/3

which is 2*3 +1 = 7/3

in decimal form is 2.33333...

now subtract (2.3333.. - 12.3 ) / 1.5

x = -6.6444

to 3 sf = -6.64

under a dilation, the point (2,6) is moved to (6,18) what is the scale factor of the dilation? enter your answer in the box

Anestetic [448]

Step-by-step explanation:

The equation of line passing through the two points is $\frac{y-y_{1} }{x-x_{1} }=\frac{y_{2} -y_{1}}{x_{2} -x_{1}}$

When substituted,the equation becomes $\frac{y-6}{x-2}=\frac{18-6}{6-2}$

which when simplified is $y=3\times x$

The line clearly passes through origin.

The distance between two points is $\sqrt{(y_{1}-y_{2} )^{2}+(x_{1}- x_{2} )^{2}}$

Distance between origin and $(2,6)$ is $\sqrt{40}$ .

Distance between origin and $(6,18)$ is $\sqrt{360}$

Scale factor is $\frac{distance\text{ }of\text{ }p_{2}\text{ from origin}}{distance \text{ } of \text{ } p_{1}\text{ from origin}}$

So,scale factor is $\frac{\sqrt{360} }{\sqrt{40} }$

which when simplified becomes 3.

a fully inflated basketball holds .34 cubic feet of air. The basketball is overinflated to hold .64 cubic feet of air. What is t

Free_Kalibri [48]

The percent of change can be calculated by finding the difference between the two volumes and then dividing by the original volume.

0.64 - 0.34 = 0.3

0.3/.34 = 0.882

This is approximately an 88.2% increase in volume.
