A cylinder-shaped drainage pipe 66 in. long measures 25.12 in. around.


What is the volume of the drainage pipe?

Answers

Answer:

Step-by-step explanation:

25.12 inches around means diameter. So radius = 12.56 inches

   volume  [tex]= \pi r^2 \times h =\pi \times 12.56^2 \times 66 = 32709.44 \ in^3[/tex]

Answer:

The volume of the drained pipe is 32692.11 in ³.

Step-by-step explanation:

Given :-

Diameter of drainage pipe = 25.12 in

So, radius , r = 25.12 in = 12.56 in

Height of drainage pipe, h = 66 in.

To Find :-

Volume of the drainage pipe

Solution :-

We know that,

Volume of cylinder = π × r ² × h

substitute the values

Volume of pipe = 3.14 × (12.56 in)² × 66 in

simplify

Volume of pipe =3.14 ×157.7536 in² × 66in

multiplying ✖ the values

Volume of the pipe = 32,692.11 in ³

Therefore, the volume of the drained pipe is 32692.11 in ³.

Answers

The increasing order of maximum number of extrema they could have is;

y = 3x² + 5y = x³ + 21x + 2y = x⁴ − 17x² + 72y = x5 + 4x³ − 5xy = x6 − 6x3 + 5x

What is the maximum number of extrema they could have in increasing order?

The extrema of a polynomial is otherwise termed it's "turning point(s)". It follows that a polynomial with a degree n would have (n-1) number of turning points. It therefore follows on this basis that the arrangement of the polynomial equations in increasing order of possible extrema they could have is;

y = 3x² + 5

y = x³ + 21x + 2

y = x⁴ − 17x² + 72

y = x5 + 4x³ − 5x

y = x6 − 6x3 + 5x

Answer:x=3, x=18, x=29, x=30, x=27

Step-by-step explanation: for problems like the first one, the angles add up to 180 since it’s just a straight line.

The second problem is a right angle so 90°. It gives you 2x and 3x. Part + part =whole so you have 5x=90 then just solve.

Angles across from each other are the same so just 145=5x then solve.

In the applet above right triangle XYZ is drawn with a 23 degrees angle. for the right triangles with an angle of 23 degrees the ratio of the leg adjacent the 23 degrees angle compared to the hypotenuse is 0.92 if the leg adjacent to the 23 degrees angle has a length of 46 units, what is the length of the hypotenuse ?

Answers

Answer:

50 ( nearest whole number)

Step-by-step explanation:

Given from the question :

Ratio of Adjacent to hypotenus = 0.92

Length of Adjacent leg = 46 units

From trigonometry :

Ratio of adjacent to hypotenus is the cosine of the angle :

Hence,

Cos 23 = adjacent / hypotenus

Cos 23 = 46 / hypotenus

0.9205048 = 46/ hypotenus

Hypotenus = 46 / 0.9205048

Hypotenus = 49.97

A potential difference of 35v is applied across the ends of a resistance of 3 ohms. How much current will flow in the resistance?

Answers

Answer:

11.67 Amperes

Step-by-step explanation:

From Ohm's law,

Ohm's law which state that a current

which flow through a conductor at a distance between two points is proportional directly to the voltage which is flowing across the two points.

I= V/R

Where

I= Current

V= potential difference =35v

R= resistance = 3 ohms

Then substitute the values we have

I = 35 / 3

I= 11.67 Amperes

The inequalities h > 42 and h < 60 represents the height requirements for an amusement park ride, where h represents the person's height in inches. Write a description that can be placed on a sign to clearly explain the rules as to who can ride the ride. You may wan to include some examples.

Answers

If h > 42 and h < 60, where h is in inches, then we can say 42 < h < 60.

This translates to "the person's height must be between 42 inches and 60 inches, excluding both endpoints".

So for example, if someone is h = 50 inches, then they can go on the ride. This is because 42 < 50 < 60 is true. I've simply replaced h with 50.

On the other hand, something like 42 < 70 < 60 is false, meaning that h = 70 isn't allowed as they are too tall.

The person cannot have a height of h = 42, and they can't have a height of h = 60 either since we're leaving the endpoints out.

As a final example, if the person is h = 40 inches, then they can't ride either because 42 < 40 < 60 is false. They are too short in this case.

What is the slope-intercept equation of the line below? A.y=2x+3 B.y=-2x-3 C.y=2x-3 D.y=-2x+3

Answers

Answer:

C.

Step-by-step explanation:

First, lets find the y-intercept. The y-intercept where the line passes through the y-axis. In this case, it is -3.

Now, to find the slope, lets find the next non-decimal point(that way it is easier on us). That would be (1,-1). Now, to get to this point from the y-intercept, we have to go left 1 unit, and up 2 units. So, the change in y over change in x = 2/1 or 2. Now, using this information, we can form the equation:

y = 2x + -3. or y = 2x - 3.

-8 < x< 3

Step-by-step explanation:

|2x+5| <11

there are two solutions, one positive and one negative ( remember to flip the inequality for the negative)

2x+5 <11  and   2x+5 > -11

Subtract 5 from each side

2x+5-5 < 11-5 and    2x+5-5 > -11-5

2x< 6           and           2x>-16

Divide by 2

2x/2 <6/2        and       2x/2 >-16/2

x <3                  and             x>-8

-8 < x< 3

Answer:

second option

Step-by-step explanation:

find angle c

angle a + angle c = 110 degree (sum of two interior opposite angle is equal to the exterior angle formed )

70 + angle c = 110

angle c = 110 - 70

angle c = 40 degree

find angle b

angle a + angle b + angle c = 180 degree (sum of interior angle of a triangle)

70 + angle b + 40 = 180

angle b + 110 = 180

angle b = 180 - 110

angle b = 70 degree

when two sides are equal the triangle can be named as isosceles triangle.

Answer:

option B

Step-by-step explanation:

∠ABD + ∠ABC = 180°            [ straight line angle ]

110° + ∠ABC = 180°

∠ABC = 180 - 110 = 70°

option A : False

Option B : True,

      Since two angles are same, the given triangle is isosceles.

option C : False

        Nothing mentioned about the sides in the figure. Though it is isosceles

      it does not mention anything about sides.

            If two angles of a triangle are congruent,

          then the sides opposite those angles are congruent.

          That is , AC = BC

Option D : False, Because only B satisfies.

Answer:

Step-by-step explanation:

I would have thought the answer would be whole numbers...

using top line....

5x-5y + 7x-15 = 180 (that is a line)

12x - 5y = 195

using bottom line

4x+ 4y +2x+ y = 180

6x + 5y =180

~~~~~~~~~~~~~~~~~~

12x - 5y = 195

6x + 5y =180

(fives cancel)

18x = 375

x = 20.83

y= 11

Answer:

x=125/6

y=11

Step-by-step explanation:

Same side interior angles have a sum of 180 if the transversal passes through a pair of parallel lines.

So we have the following two equations:

7x-15+5x-5y=180

4x+4y+2x+y=180

Let's simply(combine like terms):

12x-5y-15=180

6x+5y=180

Add 15 on both sides for first equation:

12x-5y=195

6x+5y=180

Equations are set up so we can use linear combination or elimination (adding equations together to eliminate y):

18x=375

Divide both sides by 18:

x=375/18

Simplify (reduce fraction):

x=375/18 ÷3/3=125/6

Now let's go back and find y using either equation:

6x+5y=180 with x=125/6

6(125/6)+5y=180

125+5y=180

5y=180-125

5y=55

y=11

x=125/6 and y=11
