What is the first step in proving that the sum of the measures of triangle XYZ is 180 degrees?

Answers

In geometry, the definition of a triangle is a two-dimensional closed figure with three sides. Aside from this, it is proven that the sum of the angles of a triangle is 180°. This is a triangle's innate property. Therefore, any closed shape with three sides is a triangle and it follows that the sum of the three angles is equal to 180°.

It is logical therefore, that the first step in proving this is by using the definition of a triangle.

How do you write 120% as a fraction or mixed number in simplest form?

Answers

6/5 should be correct
The word 'percent' means 'for every 100' or 'per 100'. And the word 'per' can be the fraction line that separate the numerator and denominator. 

So, 120% can be read as '120 per 100'. [tex]\frac{120}{100}[/tex]

Simplify.

[tex]\frac{120}{100} = \frac{12}{10} = \frac{6}{5}[/tex]

Convert the improper fraction into a mixed number.

[tex]\frac{6}{5} = 1 \frac{1}{5}[/tex]

So, 1 1/5 is the answer.

What is the rate of change for the relationship represented in the graph? (1 point)


A. 1/15
B.1/14
C.14
D.15

Answers

Hey there!

You can find the rate of change by taking any two points from your graph and plugging them into the following equation:

[tex] \frac{y_2-y_1}{x_2-x_1} [/tex]

Let's use the first two points you're shown from least to greatest. These are (0, 0) and (1, 15). 

Now, identify what number is which and plug them into your equation. The solution will be your rate of change. 

[tex]y_2 = 15 \\ y_1 = 0 \\ x_2 = 1 \\ x_1 = 0[/tex]

[tex]\frac{15-0}{1-0}[/tex]

[tex] \frac{15}{1} [/tex]

[tex]15[/tex]

15, or D, will be your answer. 

Hope this helped you out! :-)

The rate of change for the relationship represented in the graph is 15

What is rate of change?

The rate of change of a linear graph is the slope of the graph

From the graph, we have the following ordered pairs

(x,y) = (0,0) and (2,30)

So, the rate of change (m) is then calculated as:

[tex]m =\frac{y_2 -y_1}{x_2 -x_1}[/tex]

This gives

[tex]m =\frac{30 - 0}{2 - 0}[/tex]

Evaluate the differences

[tex]m =\frac{30 }{2 }[/tex]

Evaluate the difference

[tex]m=15[/tex]

Hence, the rate of change is 15

Thirty car pass through a certain toll booth each minute.at that rate,how many cars are expected to pass through the toll booth each half-hour

A 15
B 60
C 450
D 900

Answers

Answer:

the answer is d

Step-by-step explanation

correct on Edge

The answer is Option D)

The number of cars that are expected to pass through the toll booth each half-hour will be 900

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The number of cars that pass through the toll booth at each minute = 30

Let the number of cars to pass at each half-hour be A

1 hour = 60 minutes

half-hour = 30 minutes

So,

The number of cars to pass at each half-hour A =
The number of cars that pass through the toll booth at each minute x 30

The number of cars to pass at each half-hour A  = 30 x 30

                                                                         = 900 cars

Hence , The number of cars that are expected to pass through the toll booth each half-hour will be 900

Gene paid a deposit on a leased car. The deposit earns 2.8 percent simple annual interest. At the end of the year, the interest that is earned is $22.40. What was the amount of the original deposit?

Answers

Interest = principle * rate * time...
I = PRT...we are going to rearrange this because we are looking for the principle...

I / (RT) = P
I = 22.40
R = 2.8%...turn to a decimal = 0.028
T = 1

sub and solve
22.40 / (0.028(1) = P
22.40 / 0.028 = P
800 = P....amount of original deposit is $ 800 <==

The formula is
I=prt
I interest earned 22.4
P original deposit ?
R interest rate 0.028
T time 1 year
Solve the formula for p to get
P=I÷rt
P=22.4÷(0.028×1)
P=800

A.  First, find the slope, which  is -0.5, and then insert it into point-slope form, which is y-y1=m(x-x1), or y-1=-0.5(x+5). That's point-slope form.


B.  First, distribute -0.5 to both terms  in the parenthesis, to get y-1=-0.5x-2.5, and lastly add 1 to both sides to get the slope-intercept form of y=-0.5x-1.5
