The rubber track for a toy digger goes around four circular wheels of diameter 8 cm, as shown. (b) Calculate the length of the rubber track that goes around the four wheels. Give your answer correct to one decimal place.

Answers

Answer 1

Answer:

73.1 cm

Step-by-step explanation:

In the drawing, the rubber track is in black and the wheels are in light gray.

As we can see in the figure, the rubber track will have a length of two halfs of a circunference of radius 8 cm plus six diameters of 8 cm. So the total length is:

Length of rubber track = pi * 8 + 6 * 8 = 25.13 + 48 = 73.133 cm

Rounding to one decimal place, we have that the length is 73.1 cm

Answer 2

This question is incomplete because it lacks the diagram of the 4 circular wheels.

Find attached to this answer the appropriate diagram

Answer:

100.5cm

Step-by-step explanation:

The formula to be used in this calculation is the circumference of a circle.

The circumference of a circle can be defined as the actual length of a circle when it is stretch out(opened up) or the distance around a circle.

The formula for the circumference of a circle is given as 2πr where r = radius of the circle

Or πD where D = Diameter of the circle

In the question, we are given the diameter of the circle = 8cm

So we use the Formula

= πD

The length of the rubber track around one wheel is

= π × 8cm = 25.132741229cm

From the attached diagram, we can see we have 4 wheels.

The length of the rubber track that goes around the four wheels is calculated as

4 × 25.132741229cm = 100.53096491cm.

Approximately to one decimal place = 100.5cm

Therefore, the length of the rubber track that goes around the four wheels to one decimal place is 100.5cm

Answers

Answer:

The team lost 25 games and won 57.

Step-by-step explanation:

I am going to say what:

w is the number of games won.

As the problem states, l is the number of games lost.

The team won 7 more than twice as many games as it lost.

This means that [tex]w = 2l + 7[/tex]

A baseball team played 82 games.

This means that:

X=1-y, 6x+5y=11 using substitution method

Answers

Answer:

x=6 y=-5

Step-by-step explanation:

6x+5y=11

X=1-y

6x=6(1-y)

6x=6-6y

6-6y+5y=11

6-y=11

y=-5

x=1-y

x=1-(-5)

x=6

so,

x=6

y=-5

Answer:

[tex]y = ( - 5) \\ x = 6[/tex]

Step-by-step explanation:

[tex]x = 1 - y \\ 6x + 5y = 11 \\ \\ \\ 6(1 - y) + 5y = 11 \\ 6 - 6y + 5y = 11 \\ - 6y + 5y = 11 - 6 \\ - y = 5 \\ y = - 5[/tex]

[tex]x = 1 - y \\ x = 1 - ( - 5) \\ x = 1 + 5 \\ x = 6[/tex]

Let's check whether the answer is correct.

[tex]6x + 5y = 11 \\ 6 \times 6 + 5 \times ( - 5) = 11 \\ 36 - 25 = 11 \\ 11 = 11[/tex]

Answers

Answer:

(-6,-2)

Step-by-step explanation:

Hello! Lets get started!

By looking at this problem, we see that both equations equal 2. This makes this problem much easier!

While there are a few methods you could solve this, I will use substitution. First, I need to find what x is in terms of y!

There are many different ways you could do this, here are two:

-x = 2-2y ==> x = -2+2y

-x + 2y = -3x + 8y ==> 2x = 6y ==> x = 3y

For this problem, I am going to use the second answer, x = 3y, as it is simpler!

We need to substitute 3y in for x in either equation; I am going to use the first equation, -x + 2y = 2.

-3y + 2y = 2

-y = 2

y = -2

Now, lets solve for x!

-x + 2(-2) = 2

-x - 4 = 2

-x = 6

x = -6

After plugging the answers into both equations, we see that they are in fact true!

Therefor, our final answer is (-6, -2)

Which bank has the highest possible overdraft fee? Bank Account Terms and Conditions Bank A has a 0 dollar overdraft fee if link with savings account of 40 dollars per overdraft, Bank B has a 35 dollar overdraft fee, bank C has a 25 dollar overdraft fee, and bank D has a 25 dollar overdraft fee.
a.Bank A b. Bank B c.Bank C d.Bank D

Answers

Bank A has the highest possible overdraft fee.

An overdraft fee is charged when a payment or withdrawal from your bank account exceeds the available balance and your bank covers the transaction as part of an overdraft protection service. But in addition to covering the transaction, the bank or credit union then applies the fee.

What happens if you have an overdraft fee?

If you don't bring your balance above zero, the bank may close your account and transfer an unpaid balance to a collection agency. Another form of overdraft protection that banks may offer is an automatic transfer from a linked account to cover a purchase if you don't have enough money in checking.

What are the solutions of the equation (x – 3)2 + 2(x – 3) -8 = 0? Use u substitution to solve.
x = -5 and x = 1
x = -1 and x = 5
x= -1 and x = -7
x = 1 and x = 7

Answers

Answer:

x = -1 and x = 5

Step-by-step explanation:

What are the solutions of the equation (x – 3)² + 2(x – 3) -8 = 0? Use u substitution to solve.

(x – 3)² + 2(x – 3) -8 = 0   -------------------------------------------------------(1)

To solve this problem, we will follow the steps below;

let u = x-3

we will replace x-3 by u in the given equation:

(x – 3)² + 2(x – 3) -8 = 0  

u² + 2u -8 = 0  ----------------------------------------------------------- --------------(2)

We will now solve the above quadratic equation

find two numbers such that its product gives -8 and its sum gives 2

The two numbers are 4 and -2

That is; 4×-2 = -8    and 4+(-2) = 2

we will replace 2u by (4u -2u)  in equation (2)

u² + 2u -8 = 0

u² + 4u - 2u -8 = 0

u(u+4) -2(u+4) = 0

(u+4)(u-2) = 0

Either  u + 4 = 0

            u = -4

or

u-2 = 0

u = 2

Either u = -4    or u = 2

But  u = x-3

x = u +3

when u = -4

x = u + 3

x = -4 + 3

x=-1

when u = 2

x = u + 3

x = 2 + 3

x=5

Therefore, x = -1  and  x =5

Nadia drew a design for a copper wire sculpture as shown above.She plans to make a wire frame that includes the perimeter of the square and the circumference of the circle.She has 5 feet of copper wire.Does she have enough wire for the sculpture?

Answers

Answer:

She does not have enough wire.

Step-by-step explanation:

The complete question included a design for her sculpture. It is a circle inscribe in a square and the length of the square is 9 inches. The picture above describe the design.

She has in possession a 5 ft of copper to construct a circle inscribe in a square.

The square is 9 inch length.

Perimeter of the square = 4L

where

L = length

Perimeter of the square = 4 × 9

Perimeter of the square = 36 inches

Circumference of a circle = 2πr

r = diameter/2 = 9/2 = 4.5 inches

Circumference of a circle = 2 × π × 4.5

Circumference of a circle = 2 × 4.5 × 3.14

Circumference of a circle = 9 × 3.14

Circumference of a circle = 28.26 inches.

The sculpture will consume 36 inches for the square and 28.26 inches for the circle. The total length for the sculpture will be 36 + 28.26 = 64.26 inches.

She has 5 ft copper for the sculpture . Let us covert the inches to ft to know if the copper wire is enough.

12 inches = 1 foot

64.26 inches = ?

cross multiply

wire required for the sculpture = 64.26/12

wire required for the sculpture = 5.355 ft

She does not have enough wire.

Answer:

No she does not have enough

[tex]t+0.07t=t(1+0.07)=t(1.07)=1.07t[/tex]

There are a couple of  equivalent expressions to the function [tex]t+0.07t[/tex]. For example:

[tex]t+0.07t[/tex]

Factor:

[tex]t+0.07t=t(1+0.07)[/tex]

If you add the terms inside the parentheses:

[tex]t(1+0.07)=t(1.07)[/tex]

Find the area of each sector. Photo attached

Answers

Answer:

Area of sector: 48π in^2; Option D

Step-by-step explanation:

~ We can see that the bolded portion of the circle must be the the sector that we need to compute the area of... ~

Let us plan out this problem. If we were to find the area of the circle provided a radius of 12 inches, we could create a proportionality between the degree of the sector, and the degree of the circle ( 360 ) and the area of the sector and the area of the circle.

1. To calculate the area of this circle, let us apply the formula πr^2, such that r is 12 inches ( and let us keep π in terms of π ) ⇒ π * ( 12 )^2 ⇒ 144 * π ⇒ Area of Circle: 144π

2. Let us see this as a proportionality:

Degree of sector/ Degree of circle = Area of sector/ Area of circle

3. Now let us say x ⇒ Area of the sector. Substitute values into this formula, and solve for x through algebra:

120 / 360 = x / 144π,

120 * 144π = 360 * x,

17,280π = 360 * x,

x = 17,280π / 360,

Area of sector: 48π in^2
