She completed 65% so she has 35% more to go. ( 100% - 65% = 35%)

Multiply the length of the race by the percentage left:

40 x 0.35 = 14

She has 14 miles left.

the cost of fencing a circular field at the rate of Rs 12. per metre is Rs 2640 . find the radius of the field

Answers

Radius = 35 m 

Step-by-step explanation:Given:

Cost of fencing circular field is Rs 2640 at rate of Rs 12 per metre.

To Find:

What is the radius of the circular field ?

Solution:

 Let the radius of circular field be r metre.

Here , if we'll divide the total cost by per metre cost of fencing then we'll get circumference of the circular field.

★ Circumference = Total cost/Cost per metre ★

➯ Circumference = 2640/12

➯ 220 m

As we know that , formula of circumference is

★ Circumference = 2πr ★

⟹ 220 = 2 × 22/7 × r⟹ 220 = 44/7 × r⟹ 220 × 7/44 = r⟹ 20 × 7/4 = r⟹ 5 × 7 = r⟹ 35 = r

Hence, the radius of circular field is 35 metre.

Answer:

Solution given:

total cost =Rs 2640

rate=Rs 12/metre

We have

circumference of circle =[tex] \frac{total cost}{rate} = \frac{2640}{12} [/tex]

2πr=220m

r=[tex] \frac{220}{2π} [/tex]=35.01

r=35m(approximately)

the radius of the field is 35m.

Given:

length of rectangle = 4 units

Height of rectangle = 2x + 6 units

To find:

Not given, so I will find area and perimeter of rectangle. If you want the length of the diagonal of the rectangle, please ask me.

Steps:

Perimeter of rectangle = 2(L + B)

                                      = 2( 4 + 2x + 6 )

                                      = 2( 10 + 2x )

                                      = 2 * 10 + 2 * 2x

                                      = 20 + 4x units

Area of rectangle = L * B

                             = 4 * (2x + 6)

                             = 4 * 2x + 4 * 6

                             = 8x + 24 units²

Therefore, the perimeter of the rectangle is 20 + 4x units, and the area of the rectangle is 8x + 24 units².

Answer:

  C.  26

Step-by-step explanation:

The two marked angles are "vertical angles." They are congruent.

  x +20 = 3x +8 . . . . . congruent angles have the same measure

  12 = 2x . . . . . . . . . subtract x+8 from both sides

  6 = x . . . . . . . . . divide by 2

  ∠PTQ = (x+20)° = (6+20)° = 26°

Answer:

Solutions given:

we have

<RTS=PTQ[vertically opposite angle are equal]

so

3x+8=x+20°

3x-x=20-8

2x=12

x=12/2=6

x=6

m<PTQ=6+20=26°

A store sells gas and containers. One customer buys 2 containers and 8 gallons of gas for $38.06. Another customer

buys 1 container and 3 gallons of gas for $15.76.

Enter the price ,in dollars, of 1 container

Answers

Answer:

$5.95

Step-by-step explanation:

Given :

Let containers = c ;Gallon of gas = g

2c + 8g = 38.06 - - - (1)

c + 3g = 15.76 - - - - (2)

From (2) :

c = 15.76 - 3g

2(15.76 - 3g) + 8g = 38.06

31.52 - 6g + 8g = 38.06

2g = 6.54

g = 6.54 / 2

g = 3.27

Recall :

c = 15.76 - 3g

c = 15.76 - 3(3.27)

c = 5.95

The lateral area of a cylinder is 100pi in^2. If its dimensions are reduced to one-fifth their original length, what would its new area be?

Answers

Answer:

4pi in^2

Step-by-step explanation:

Lateral surface area of a cylinder = 2πrh

π = pi

r = radius

h = height

Let me illustrate with an example

A cylinder has the following dimensions

r = radius = 20  

h = height  = 10

lateral area = 2 x π x 20 x 10 = 400π

If dimensions are reduced to one-fifth their original length, new dimensions are

r = radius = 20  x 1/5 = 4

h = height  = 10 x 1/5 = 2

New lateral area = 2 x 4 x 2 x π = 16π

change in lateral area = 400π / 16π = 25

If dimensions are reduced by 1/5, lateral area would reduce by 25

100 pi / 25 = 4

Answers

Answer:

Amount of paper need = 140 cm²

Step-by-step explanation:

Given:

Length of rectangular prism = 5 cm

Width of rectangular prism = 5 cm

Height of rectangular prism = 4 cm

Base of triangular side = 5cm

Height of triangular side = 6 cm

Find:

Amount of paper need

Computation:

Amount of paper need = Curved surface area of rectangular prism +  Curved surface area of square pyramid

Amount of paper need = 2h(l + b) + 4[Area of triangle]

Amount of paper need = 2h(l + b) + 4[(1/2)(b)(h)]

Amount of paper need = (2)(4)(5 + 5) + 2[(5)(6)]

Amount of paper need = (8)(10) + 2[30]

Amount of paper need = 80 + 60

Amount of paper need = 140 cm²

The function g(x) = x2 is transformed to obtain function h:

Which statement describes how the graph of h is different from the graph of g?

A.
The graph of h is the graph of g vertically shifted down 1 unit.
B.
The graph of h is the graph of g vertically shifted up 1 unit.
C.
The graph of h is the graph of g horizontally shifted right 1 unit.
D.
The graph of h is the graph of g horizontally shifted left 1 unit.

Answers

Answer:

the answer is D

Step-by-step explanation:

The graph of h is the graph of g horizontally shifted left 1 unit.

Given that,

The function [tex]\rm g(x) = x^2[/tex]is transformed to obtain function h:

h(x) = g(x) + 1.

We have to determine,

Which statement describes how the graph of h is different from the graph of g?

According to the question,

The first transformation is vertical transformation.

This type of transformation shifts the graph up or down relative to the parent graph.

The graph will shift up if we add a positive constant to each y- coordinate whereas the graph will shift down if we add a negative constant.

This type of transformation shifts the left or right relative to the parent graph.

This takes place when we add or subtract coordinates from the x-axis before the function is applied.  

The h(x) is horizontally shifted left 1 unit

The equation is,

[tex]\rm h(x) = g(x)-1[/tex]

The h(x) is horizontally shifted left 1 unit,

The equation is,

[tex]\rm h(x) = g(x)+1[/tex]

Hence, The graph of h is the graph of g horizontally shifted left 1 unit.
