The cost of having a plumber spend h hr at your house if the plumber charges ​$30 for coming to the house and​ $x per hour for labor. The expression for the cost of the plumber coming to the house is how many dollars.

Answer:

B is your answer

Step-by-step explanation:

Why this is, is because it is parallel an all four sides while a trapezoid isn't parallel on all four sides. So that means that B is not a trapezoid.

Figure B is not a trapezoid

A trapezoid is a quadrilateral with at least one pair of parallel sides.

The non-parallel sides may have different lengths, and its angles can vary.

It combines characteristics of both triangles and parallelograms in its geometric properties.

Figure A represents a trapezoid cos it has a lone pair of parallel lines.

Figure B is not a trapezoid but a parallelogram because it has 2 pairs of parallel lines.

Answer:

A. 5/9    B. 1/6.

Step-by-step explanation:

Total possible events = 6*6 = 36.

A.  The possible combinations for the sum  being <= 6 are:

1 ,1  2,2   3,3   1,2  1,3  1,4  1,5  2,1   2,3  2,4  3,1   3,2  3,3  4,1  4,2  5,1

= 16

So Probability of Sum > 6 =  (36-16) / 36

= 20/36

= 5/9.

B.   Possible combinations where the sum is divisible by 6  are

3,3  2,4  4,2  1,5  5,1. 6,6   =   6.

So the required probability =  6/36

= 1/6.

Answer:

Step-by-step explanation:

There would be 216 outcomes because

6*6=36 outcomes so

6*6*6, or 36*6, = 216.

When 3 fair dice are rolled then there are 216 possible outcomes.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

When 2 fair dice are rolled there are 36 possible outcomes.

Now,

Since, When 2 fair dice are rolled then possible outcomes = 6 x 6 = 36

So, When 3 fair dice are rolled then possible outcomes = 6 x 6 x 6

                                                                                      = 216

Thus, When 3 fair dice are rolled then there are 216 possible outcomes.

Answer:b

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Range of the graph is the ALLOWED y-values. The y-axis is number of gallons left in tank. So, it cannot be NEGATIVE number of gallons, so 0 is the lower limit of the range.

As we can see from the axis of the graph, we see where the line cuts the y-axis, that is the upper limit of number of gallons he starts off with. The y-intercept (y-axis cutting point) is 12.

So we can say that the range is  0 ≤ y ≤ 12

Correct answer is B

Answer:

ANSWER

[tex]A. \: \: y = 5x + \frac{3}{4} [/tex]

EXPLANATION

The slope-intercept form of an equation is given by;

[tex]y = mx + c[/tex]

wherever m is the slope and c is y-value of the y-intercept.

It was given that the slope is 5.

This implies that,

[tex] m = 5[/tex]

The y-intercept is

[tex](0, \frac{3}{4})[/tex]

This means that,

[tex]c = \frac{3}{4} [/tex]

We plug in the values to obtain,

[tex]y = 5x + \frac{3}{4} [/tex]

The correct choice is A.

Answer:

Step-by-step explanation:

The first triangle is a 30-60-90 right triangle.  We have a Pythagorean triple associated with this type of triangle that is

 (x , x√3, 2x) which represent the side lengths across from the

(30°, 60°, 90°)

We have the side length across from the 30° as 14.  That means that x = 14.  In our figure, "y" is across from the 60° which means that the side length is

14√3, which has a decimal equivalency of 24.24871131; in our figure "x" is the hypotenuse which is 14(2) which is 28.

For the intents and purposes of keeping you not confused:

x = 28, y = 14√3 (or 24.24871131)

The next triangle is also a right triangle but this one is a 45-45-90.  The Pythagorean triple for that triangle is

( x , x , x√2 ) as the side lengths across from the

(45°, 45°, 90°)

We have a side length across from the 90° as 18 units long; therefore, according to our Pythagorean triple:

x√2 = 18 and

x = [tex]\frac{18}{\sqrt{2} }[/tex] and, rationalizing the denominator:

[tex]x=\frac{18\sqrt{2} }{2}[/tex] so

x = 9√2, which has a decimal equivalency of 12.72792206.

Summing up again:

x = 9√2 (or 12.72792206)

Answer:

Long diagonal: 12.12 yd

Short diagonal: 7 yd.

Step-by-step explanation:

As you can see, 4 righ triangles are formed.

The larger diagonal divides the angle ∠AFM=60° into two angles of 30° each.

Then,  choose one the triangles that has the angles of 30°. The hypotenuse will be the side lenght of 7 yards, the long diagonal (D) will be twice the adjacent side and the short diagonal (d) will be twice the opposite side.

Then:

- Long diagonal:

[tex]\frac{D}{2}=7*cos(30\°)=6.06yd\\\\D=2(\frac{D}{2})=2(6.06yd)=12.12yd[/tex]

- Short diagonal:

[tex]\frac{d}{2}=7*sin(30\°)=3.5yd\\\\d=2(\frac{d}{2})=2(3.5yd)=7yd[/tex]

Answer:

The length of diagonals are 7 yd and 12.12 yd

Step-by-step explanation:

Let the point of intersection called as 'D'

<AFD = <MFD =60/2 = 30°

Then < AFM = <AFD + <MFD

Consider the ΔAFD

The angles are 30°, 60° and 90 then sides are in the ratio

1 : √3 : 2

The two diagonals are MA and FR

MA = MD + AD = 7/2 + 7/2 = 7 yd

FR = FD + RD =  7√3/2 +  7√3/2 =  7√3 = 12.12 yd

Therefore the length of diagonals are 7 yd and 12.12 yd

Final answer:

To find the volume of the soup can, one must use the formula for the volume of a cylinder, [tex]V = (pi)r^2h[/tex]. After substituting the given measurements, the calculated volume, rounded to the nearest tenth, is approximately 673.9 cubic centimeters.

Explanation:

The student asked about the volume of a cylindrical soup can with a given radius and height. To calculate this, the formula for the volume of a cylinder, which is V = \\(pi)r^2h, is used. Here, r represents the radius of the cylinder's base, and h represents the height of the cylinder. Substituting the given values into the formula, we get [tex]V = (pi)(4.3 cm)^2(11.6 cm)[/tex]. The calculated volume will give us the amount of space inside the soup can, measured in cubic centimeters (cm^3).

Answer:

1) The expression to represent the pattern is 11 + 8n

2) The expression to represent the pattern is 80 - 9n

Step-by-step explanation:

1) * Lets study the pattern;

- 19 , 27 , 35 , 43 , ..................

∵ 27 - 19 = 8

∵ 35 - 27 = 8

∵ 43 - 35 = 8

∴ The difference is constant between each two consecutive terms

∴ It is an arithmetic sequence

* Lets take about the arithmetic sequence

- If the first term is a and the constant difference is d

∴ a1 = a , a2 = a + d , a3 = a + 2d , a4 = a+ 3d , ........

∴ an = a + (n - 1)d, where n the position of the term in the sequence

* Now we will use this rule to find the expression of our pattern

∵ a = 19 , d = 8

∴ an = 19 + (n - 1)(8) ⇒ an = 19 + 8n - 8 ⇒ an = 11 + 8n

* Lets check it;

∵ a3 = 11 + 8(3) = 11 + 24 = 35 ⇒ true

∴ The expression to represent the pattern is 11 + 8n

2) * Lets study the pattern;

- 71 , 62 , 53 , 44 , ..................

∵ 62 - 71 = -9

∵ 53 - 62 = -9

∵ 44 - 53 = -9

∴ The difference is constant between each two consecutive terms

∴ It is an arithmetic sequence

* We will use the same rule above to find the expression of the pattern

∵ a = 71 , d = -9

∴ an = 71 + (n - 1)(-9) ⇒ an = 71 + -9n + 9 ⇒ an = 80 - 9n

* Lets check it;

∵ a4 = 80 - 9(4) = 80 - 36 = 44 ⇒ true

∴ The expression to represent the pattern is 80 - 9n

x = 4.8

With angles like this these ones, the 2 lines equal the same amount. To find the length of one of the lines, you multiply the given lengths.

So, for the first angle, the line with both angles has a 4 and 6, so the length of the line is 24.

Since the lines are equal, to find the length of x you take 24 and divide it by 5, which gives you 4.8, or 24/5.

This means x = 4.8.

To double check, you can simply multiply 4 and 6, then 5 and 4.8. If the answers are the same, it is correct.

This applies to all 3 angles shown.

Hope this helps!

Answer:

basketball hoop= 10 feet high

steve=5 feet tall

hes standing 12 feet away

so  i would say 3 feet away

The distance from the top of Steve's head to the hoop is 13 feet.

Given information in the question is the height of basketball hoop is 10 feet, height of Steve 5 feet and the distance from hoop to him is 12 feet.

Therefore the distance from the top of Steve's head to the hoop is also 12 feet.

Also the distance from the top of Steve's head and the top of Hoop is (10 - 5) feet = 5 feet.

Therefore calculating the distance from top of Steve's head to the hoop by using Pythagoras Theorem -

Let the required distance is d feet .

⇒  [tex]d = \sqrt{12^{2} + 5^{2} }[/tex]

Answer:

  c. Reflect across the y-axis, translate 3 right and 2 down

Step-by-step explanation:

You want a description of the transformation of g(x) = ln(x) into f(x) = ln(3 -x) -2.

Reflection across the y-axis is the result of replacing x by -x in a function. That is, f(x) = g(-x) will reflect g(x) across the y-axis.

Translation right h units and up k units is the result of the transformation ...

  f(x) = g(x -h) +k

The given function f(x) can be written as ...

  f(x) = g(-(x -3)) -2

The first transformation is replacement of x by -x:

  f(x) = g(-x) . . . . . . . . reflection over the x-axis

The second transformation is replacement of x by x-3, and adding -2 to the function value:

  f(x) = g(-(x -3)) -2 . . . . translation of the reflected function right 3, down 2

The graph of g(x) = ln(x) is transformed to the graph of f(x) = ln(3 -x) -2 by reflection over the y axis, then translation right 3 and down 2, choice C.

First you would need to move the variable causing it to change its sign

5x=10-y

Then divide both sides by 5

X=2-1/5y

Then you are left with your answer:

x=2-1/5y
