True or false and why: Angles that are congruent are also equal

Mathematics

taurus [48]3 years ago
7 0

Answer: True

Angles are congruent if they have the same angle measure in degrees. They can be at any orientation on the plane. In the figure above, there are two congruent angles. Note they are pointing in different directions.

Find the slant height of a square pyramid with base edges of 12 cm and an altitude of 8 cm?
liberstina [14]
To find the slant height we must take apart the pyramid first. Let us cut it in half. There we can easily see that the slant height is really just the hypotenuse of the triangle formed by half the base and the altitude.

Half the base length would be 6 cm.

Using the Pythagorean therom:

a² + b² = c²
6² + 8² = c²
36 + 64 = c²
100 = c²
c = 10

The slant height should be 10 cm. Hope this helps!

Which expression can be simplified to find the slope of the trend line in the scatterplot?
Maslowich

Answer:

1. \frac{24-79}{12-2}

Step-by-step explanation:

We have been given a graph of a scatter-plot and we are asked to find the correct expression than can be solved to find the slope of the trend line in the scatter-plot.

Since we know that slope of a line can be found by dividing the difference of the y-coordinates of 2 points on a line by difference of the x-coordinates of these same points.  

\text{Slope}=\frac{y_2-y_1}{x_2-x_1}  

We can see that (2,79) and (12,24) are two given points of our trend line. So let us substitute x and y-coordinates of our given points in slope formula to find the our desired expression.    

x_1=2

x_2=12

y_1=79

y_2=24

\text{Slope}=\frac{24-79}{12-2}

Therefore, the expression \text{Slope}=\frac{24-79}{12-2} can be solved to find the slope of the trend line in the scatter-plot and 1st option is the correct choice.

I BET NO ONE KNOWS THIS y varies jointly as x and z. y=20 when x=2 and z=5 . Find y when x=3 and z=6
Greeley [361]

Hello!

If y varies jointly with x and z, it'll mean that x and z are being multiplied by a factor "k", to equal y.

To give you a visual, this is what I mean.

y=kxz

That means we'll want to find k with the first point we're given: (2,20,5)

20=k(2)(5)

20=10k

k=2

Which means our equation is:

y=2xz

Now, let's plug in the x and z from the other point to find y.

y=2(3)(6)

y=36

Hope this helps!
