You find the distance of all sides to both triangle then match up the sides and see if they are similar

Given two triangles on a coordinate plane, you can check whether they are congruent by using the distance formula to find the lengths of their sides. If three pairs of sides are congruent, then the triangles are congruent vy the above theorem.

In a class of 23 student the girls were 7 more than the boys how many boys were in the class

Softa [21]

Answer:

x=# of boys

x+7=# of girls

x+x+7=25

2x+7=25

2x=25-7

2x=18

x=18/2

x=9 boys

x+7=16 girls

If you don't understand variables use trial and error.

List at least two technology tools that can help with calculating future value of an investment. Using complete sentences, expla

Setler79 [48]

Answer:

scientific or graphing calculator
TVM solver
spreadsheet

Step-by-step explanation:

For many future-value calculations, a scientific calculator is a sufficient tool. Of course, one must know the appropriate formula to use.

A good alternative when the calculation is a little messy is a TVM solver or special-purpose financial calculator. I prefer this tool because it requires little more than entering numbers in to the right slots.

Most modern spreadsheet programs and apps come with financial formulas built in. So, they, too, can be easy tools to use for calculating future value. These are especially handy when a number of scenarios need to be explored. (I always have to look up the formulas to see which one is appropriate and what its inputs are. So, I find a spreadsheet less useful for a simple calculation.)

The equation of line q is 5y - 4x = 10. Write the standard fom of the equation of the line that fits the following description:

kumpel [21]

<h3>Answer: -4x+5y = 100</h3>

===================================================

Explanation:

The given equation is the same as -4x+5y = 10

It is of the form Ax+By = C, where A = -4, B = 5, C = 10

Anything parallel to Ax+By = C is of the form Ax+By = D. The only difference is the C has changed to a D.

This means anything parallel to -4x+5y = 10 is -4x+5y = D, where D is not equal to 10, but it could be any other number.

Plug in the coordinates of (-15,8) to find the value of D

-4x+5y = D

-4(-15)+5(8) = D

60+40 = D

100 = D

D = 100

We have -4x+5y = D update to -4x+5y = 100

The equation -4x+5y = 100 is parallel to -4x+5y = 10, and it goes through (-15,8)

Parallel lines have the same slope, but different y intercepts.

Note how Ax+By = C has a slope of m = -B/A. This means A cannot be zero.

A water balloon has a diameter of 6 inches. How many cubic inches of water does it contain when it is 3/4 full

Travka [436]

Below are the choices that can be found from other sources:

A) 36 pi
B) 6 pi 
C) 27 pi 
D) 216 pi 
E) 48 pi

A sphere's volume is (4/3)*pi*r^3.
The diameter of the balloon is 6 inches. The diameter is twice the radius. The radius is 3 inches. 

(4/3)*pi*3^3 = 36 * pi 

But the balloon is only 3/4 full. So 

36 * (3/4) * pi = 27 * pi. 

The balloon has 27 pi cubic inches of water.
