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

Answer:

1: No, x is raised to a power

2: Yes, can be solved in the form of y = mx + b

3: If this is supposed to be x + y = 45, then yes because it can be solved in the form of y = mx + b

4: Yes, it is in the form of y = mx + b

5: Yes, it is in the form of y = mx +b, it has a slope of zero and will be a horizontal line, which will pass the vertical line test

6: No, x is raised to a power.

7: No, x is raised to a power.

8: No, x is raised to a power

9: Is that supposed to be pi? If so, yes, it is in the form of y = mx + b

Step-by-step explanation:

[tex]V = \frac{4}{3} \pi r^3[/tex]               2km = radius

[tex]V=\frac{4}{3}\pi (2)^3[/tex]

[tex]V = \frac{4}{3}\pi (8)[/tex]

[tex]V = \frac{4}{3}(8)\pi[/tex]

[tex]V =\frac{32}{3}\pi[/tex]     [tex]\pi =3.14[/tex]

[tex]V = \frac{32}{3}(3.14)[/tex]

[tex]V = 33.493[/tex]

V≈ 33.49        

Using π on the calculator

[tex]V = \frac{32}{3} \pi[/tex]

[tex]V = 33.510[/tex]

V ≈ 33.51

Answer:

16

Step-by-step explanation:

The area of a parallelogram can be found with the formula: A=bh (area equals base times height)

The base of this shape is 4, we multiply this by the height which is four.

Four times four equals 16

So that's the answer, 16.

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:

x = 9

Step-by-step explanation:

1: Make an equation

[tex]180 = 54 + 6x + 8 + 180 - (11x + 17)[/tex]

2: factor the -1

[tex]180 = 54 + 6x + 8 + 180 -11x - 17[/tex]

2: move x to one side

[tex]11x - 6x = 54 + 8 + 180 - 17 - 180[/tex]

3: simplify

[tex]5x = 45[/tex]

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.

Answer:

y=x-2

Step-by-step explanation:

set up in y1-y2/x1-x2

2 - (-2)/4 - 0

4/4 = 1

so x=1 and the y intercept is -2

so the answer is C

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 :

What we have to calculate :

Performing Calculations :

Here we have been given with two equations,

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.

Answer:

The sales tax is equal to 5.6%

Step-by-step explanation:

To solve first we have to subtract the item's cost before sales tax from the total due. 91.08 - 86.25 = 4.83.

Next we take the amount we payed as tax and divide it by the pre-tax price. 4.83/86.25 = 0.056

Lastly we take 0.056 and convert it to a percentage. This can be accomplished by moving the decimal sign to 2 times to the left or multiplying the tax rate by 100.

The sales tax percentage is equal to 5.6%

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

Answer:

168.75

Step-by-step explanation:

135.00 + 25% is 168.75

168.75 - 25% is 135.00

= 48cm²

To work out the area you must firstly multiply 8 by 12.

1) 8 x 12 = 96

Now you have to divide it by 2.

2) 96 / 2 = 48

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

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]

In this problem:

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.

You already have the answer. It is "One type of proof is a two-column proof. It contains statements and reasons in columns. Another type is a paragraph proof, in which statements and reasons are written in words. A third type is a flowchart proof, which uses a diagram to show the steps of a proof." which looks correct to me.
