You already have the answer. It is "One type of proof is a two-column proof. It contains statements and reasons in columns.

A third type is a flowchart proof, which uses a diagram to show the steps of a proof." which looks correct to me.

What’s the answers and now would I work this out ?

Answers

Answer:

15 cm²

Step-by-step explanation:

To find the volume of a prism you multiply the area of the end face (pentagon in this example) by the length (9 cm). Here you would reverse that and divide the volume by the length to find the area. 135/9 is 15 so the area of the pentagon is 15 cm².

In equation form would be:

V=A×L    [V=volume   A=area   L=length]

So if you do inverse operations you would divide the volume by the length to get the area.

V/L=A

In right triangle ABC below, CD is the altitude to hypotenuse AB. If CD=6 and the ratio of AD to AB is 1:5, determine and state the length of BD.

Answers

Step-by-step explanation:

the altitude makes a right angle at hypotenuse

cd^2+ ad^2 = ac^2

36+ (h/5)^2 = ac^2

ad/ab = 1/5; ad/h = 1/5; ad=h/5

similarly

bd^2+cd^2 = bc^2

(4/5)^2+ 36 = bc^2

ac^2+bc^2 = ab^2

36+h^2/25+ 16/25h^2+36 = h^2

h= 15

bd/ab = 4/5

bd= .8*15=12

Answers

Answer:

The input x = 1 has many outputs.

The graph is a vertical line.

Step-by-step explanation:

Hi there!

A function is defined as a relation that only gives one output for every given input. For every x-value, there is only one y-value.

Because the x-value of 1 gives us an infinite number of y-values, this is therefore not a function.

More generally, no vertical line is a function for this reason.

Scores on an exam follow an approximately normal distribution with a mean of 76. 4 and a standard deviation of 6. 1 points. What percent of students scored above 75 points?.

Answers

Using the normal distribution, it is found that 59.09% of students scored above 75 points.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

The mean is [tex]\mu = 76.4[/tex].The standard deviation is [tex]\sigma = 6.1[/tex].

The proportion of students who scored above 75 points is 1 subtracted by the p-value of Z when X = 75, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{75 - 76.4}{6.1}[/tex]

[tex]Z = -0.23[/tex]

[tex]Z = -0.23[/tex] has a p-value of 0.4091.

1 - 0.4091 = 0.5909

0.5909 = 59.09% of students scored above 75 points.

Find the measures of each numbered angles

Answers

Answer:

∠ 1 = 109° , ∠ 2 = 29° , ∠ 3 = 71°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

∠ 1 + 35° + 36° = 180°

∠ 1 + 71° = 180° ( subtract 71° from both sides )

∠ 1 = 109°

-------------------

∠ RVU and ∠ 1 are adjacent angles on a straight line and sum to 180° , then

∠ RVU + ∠ 1 = 180°

∠ RVU + 109° = 180° ( subtract 109° from both sides )

∠ RVU = 71°

In Δ RVU

∠ 2 + 80° + 71° = 180° ( sum of angles in triangle )

∠ 2 + 151° = 180° ( subtract 151° from both sides )

∠ 2 = 29°

-------------------------

∠ 3 and ∠ RVU are vertically opposite angles and are congruent , then

∠ 3 = 71°

Δ UVT has: ∠V₁ = 180⁰ - ∠TUV - ∠VTU = 180⁰ - 35⁰ - 36⁰ = 109⁰

We have: ∠RVU = ∠V₃ = 180⁰ - ∠V₁ = 180⁰ - 109⁰ = 71⁰

ΔRVU has: ∠U₂ = 180⁰ - ∠URV - ∠ RVU = 180⁰ - 80⁰ - 71⁰ = 29⁰

Answer:

∠V₁ = 109⁰∠U₂ = 29⁰∠V₃ = 71⁰

Hi please help i am stuck with this question i will mark for brainliest


And 100. Point

Answers

Answer: 9

Step-by-step explanation:

First solve the system (using elimination):

x-y=7...(1)

3x+2y=26...(2)

Multiply equation 1 by -3

 -3x+3y=-21

+ 3x+2y=26

 -----------------

     5y=5

      y=1

Substitute y=1 into equation 1

x-y=7

x-(1)=7

x=8

Let a=8 (x=a) and y=1 (y=b)

a + b

= (8) + (1)

= 9

Information provided with us :

x is assumed as a y is assumed as b

What we have to calculate :

Value of a + b ?

Performing Calculations :

Here we have been given with two equations,

x - y = 7 (First equation) 3x + 2y = 26 (Second equation)

From the first equation we would be getting a value of x and that value of x we would substitute in the second equation.

x - y = 7

x = 7 + y

Now, substituting it in the second equation :

3x + 2y = 26

3 (7 + y) + 2y = 26

3 × (7 + y) + 2y = 26

21 + 3y + 2y = 26

21 + 5y = 26

5y = 26 - 21

5y = 5

y = 5 / 5

y = 1

Therefore, value of y is 1.

Now, substituting this value of y as 1 in the first equation.

x - y = 7

x - 1 = 7

x = 7 + 1

x = 8

Therefore, value of x is 8.

Value of a + b :-

x = a = 8

y = b = 1

Now,

a + b

8 + 1

9

Henceforth, value of a + b is 9.
