(3,7)

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

since x>100, then 19-20x and 20-19x would obviously be negative and x-10 would be positive.

Therefore we have (20x-19)-(19x-20)-(x-10) = 20x-19-19x+20-x+10 = 11

Answer:

Length of the Rectangle is to be considered as the circumference of the resulting cylinder and the width of the rectangle should be considered as the height of the cylinder only then we get the maximum volume of the cylinder which is 47.77[tex]in^3[/tex]

Step-by-step explanation:

The given dimensions are

Width of the rectangle is  6inches.

Length of the rectangle 10inches.

Now we need to choose in what orientation we need to use the length and the width of the rectangle so that it can be rolled into a rectangle and we get the maximum volume of the resulting cylinder.

so lets consider two cases

CASE-1: width of the rectangle is to be rolled as the circumference of the cylinder and length of the rectangle is to used as the height of the cylinder

 2*pi*r = 6

      r = [tex]\frac{6}{2pi}[/tex]

      r = [tex]\frac{3}{pi}[/tex] Inch

and the height = 10inch.

Volume of the resultant cylinder will be

   = [tex]pi*r^2*h[/tex]

   = [tex]pi*(\frac{3}{pi} )^2*10[/tex]

   = [tex]\frac{9}{pi}*10[/tex]

   = [tex]\frac{90}{pi}[/tex] = 28.662 [tex]in^3[/tex]

CASE-2: When the length of the rectangle is to used as the circumference of the resultant cylinder and the width of the cylinder is used as the height of the cylinder.

2*pi*r= 10

         r =  [tex]\frac{5}{pi}[/tex]

and the height of the cylinder is 6 inch

Now the volume of the cylinder will be

 Volume= [tex]pi*r^2*h[/tex]

              = [tex]pi*(\frac{5}{pi} )^2*6[/tex]

              = [tex]\frac{25}{pi}*6[/tex]

              = [tex]\frac{150}{pi}[/tex] = 47.77[tex]in^3[/tex]

Clearly we have the second case in which the resulting Cylinder will have the maximum volume.

Therefore the CASE-2 will provide the maximum Volume of 47.77[tex]in^3[/tex] to the resulting cylinder in which the length of the rectangle is to be considered as the circumference of the Cylinder and the width of the rectangle is to be considered as the height of the cylinder.

Step-by-step explanation:

v² - 11v + 18 = 0 ← in standard form

(v - 2)(v - 9) = 0 ← in factored form

Equate each factor to zero and solve for v

v - 2 = 0 ⇒ v = 2

v - 9 = 0 ⇒ v = 9

solutions are v = 2, v = 9

(14)

5x² - 12x + 7 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 7 = 35 and sum = - 12

The factors are - 5 and - 7

Use these factors to split the x- term

5x² - 5x - 7x + 7 = 0 ( factor the first/second and third/fourth terms )

5x(x - 1) - 7(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(5x - 7) = 0

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

5x - 7 = 0 ⇒ 5x = 7 ⇒ x = [tex]\frac{7}{5}[/tex]

solutions are x = 1, x = [tex]\frac{7}{5}[/tex]

Hope this helps!:)

Answer:

11a

Step-by-step explanation:

You can combine like terms. Since they both have a after the number, you can just think of it as an addition problem. 6+5= 11. 6a+5a=11a.

Answer:

Step-by-step explanation:

Given;

Total people surveyed = 1700 people

Total number of people that owned car = 425 people;

Percentage of people satisfied are those that owned car = 425/1700 * 100

Percentage of people satisfied = 42500/1700

Percentage of people satisfied = 25%

Hence 25% of the people surveyed were satisfied with the​ car

Answer:

1.

1) The area of the sector is 168.8π mi²

2) The area of the sector is 529.9 mi²

2.

1) The area of the sector is 42.3π in²

2) The area of the sector is 132.7 in²

Step-by-step explanation:

The formula of the area of a sector in a circle is A = [tex]\frac{x}{360}[/tex] × π r², where

1.

∵ The central angle subtended by the arc of the circle is 270°

∴ x = 270°

∵ The radius of the circle is 15 mi.

∴ r = 15

→ Substitute them in the formula of the area above

∵ A = [tex]\frac{270}{360}[/tex] × π (15)²

∴ A = 168.75π mi²

→ Round it to the nearest tenth

∴ A = 168.8π mi²

1) The area of the sector is 168.8π mi²

∵ π = 3.14

∴ A = 168.75 × 3.14

∴ A = 529.875 mi²

→ Round it to the nearest tenth

∴ A = 529.9 mi²

2) The area of the sector is 529.9 mi²

2.

∵ The central angle subtended by the arc of the circle is 90°

∴ x = 90°

∵ The radius of the circle is 13 in

∴ r = 13

→ Substitute them in the formula of the area above

∵ A = [tex]\frac{90}{360}[/tex] × π (13)²

∴ A = 42.25π in²

→ Round it to the nearest tenth

∴ A = 42.3π in²

1) The area of the sector is 42.3π in²

∵ π = 3.14

∴ A = 42.25 × 3.14

∴ A = 132.665 in²

→ Round it to the nearest tenth

∴ A = 132.7 in²

2) The area of the sector is 132.7 in²

Answer: 3/64

Step-by-step explanation:

Dividing by 8 is the same thing as multiplying by the reciprocal (just flip the fraction). Since 8/1 is the same things as 8, here, the reciprocal is 1/8. So just multiply 3/8 by 1/8. You should get 3/64. Hope this helps!

Answer:

a)5/7

b)12/8 or 1 4/2 or 1/2

c)1/6

Step-by-step explanation:

Answer:

y=4/5x+2

Hi! first things first, you want to find the slope. you do that by taking both y values, in this case they are 2 and -6.

then, you need to identify the two 2 x values, 5 and -5.

next, follow this formula: Y2-Y1/X2-X1. y value#2 is -6, and y value#1 is 2. subtract those numbers, to end up with -8. this will go on top of the fraction.  x value#2 is -5, x value#1 is 5. subtract (=-10) and put it on the bottom of the fraction.

now you have your slope! we now have y= -8/-10, or simplified is 4/5.

Now we find the y intercept. to do that, you want to pick a set of points. i'm going to be using (5, 2) because it will be the easiest.

lastly, set up the equation to find the y int: y- y1= m (x- x1)

y- 2= 4/5 (x- 5) = 2

Answer: I am fairly sure the answer is 56

Step-by-step explanation:

If the credentials to this question match with mine, your answer should be 56. I am sorry if this is wrong.

Answer:

y-3

Choose a point, any is fine. (I chose point c)

Count how many spaces it to get from point C to where point C' is on the x axis. (It already gave it to us. its 8)

Then count how many spaces it takes to get to C' on the y axis. (In this case you are counting down because A'B'C' is beneath ABC.)

I am extremely terrible at explaining things but hope this helps.

Answer:

Y = 1/3x + 6

Step-by-step explanation:

You are trying to find the b in y=mx + b so you plug in the information you have

7=1/3 (3) + b

1/3 *3 = 1

7 = 1 +b

-1 - 1

6=b

So Y = 1/3x + 6

Answer:

2 batches

Step-by-step explanation:

A cookie factory uses 1 1/3 barrels of oatmeal in each batch of cookies

The factory used 2 2/3 barrels of oatmeal yesterday

Therefore the batches of cookies that were made yesterday can be calculated as follows

1 batch= 1 1/3 barrels

x = 2 2/3 barrels

Cross multiply

4/3 x = 8/3

x= 8/3 ÷ 4/3

x = 8/3 × 3/4

x= 2

Hence 2 batches will be produced
