I hope this helps you, I haven't done this for quite some time. Sorry it took me just now to find your question.

Given parameter:

Diameter of the ferris wheel  = 80m

Unknown:

Distance covered in one complete rotation = ?

Solution:

One complete rotation will sweep through the circumference of the wheel.

So,

  One complete rotation = Circumference of circle  = 2 [tex]\pi[/tex] r

Where r is the radius;

         Radius here is [tex]\frac{80}{2}[/tex]  = 40m

So circumference = 2 x [tex]\pi[/tex] x 40 = 80[tex]\pi[/tex]

The distance the wheel sweeps through will be 80π m

Answer:

The answer is x = -35

Hello.

To answer this question, follow the order of operations.

10-7(3+2)7²

10-7·5·7²

10-7·5·49

10-35·49

10-1715

-1705

Step-by-step explanation:

[tex]\tt{10-7(3+2)7^2}[/tex]

[tex]\tt{10-7(3+2)\times 49}[/tex] ____(as 7² is 49)

[tex]\tt{10-7 \times 5\times 49}[/tex]

As we know, Multiply first,

[tex]\tt{10-7 \times 5\times 49}[/tex]

[tex]\tt{10-1715}[/tex]

[tex]\tt{-1705}[/tex]

Answer:

The answer is 2(3)+6

Step-by-step explanation:

The perenthesis means multiplication so you would first do 2 times three which is 6 and then 6+6=12 and the first expresion is 2(a+3) a=3 to solve that you would do whats in the perenthesis 3+3 which equals 6 and then the 6 in the perenthesis means mulitplication. so then you would do 2 times 6 and get 12. so the 3rd one is the answer.

Answer:

1/5

Step-by-step explanation:

5 = 1/5

6= 1/6

1/6= 6/1 (or just 6)

5/6= 6/5

Do you see the pattern?

Every number has a reciprocal except for 0. There is nothing you can multiply by 0 to create a product of 1, so it has no reciprocal.

Answer:

1/5.

Step-by-step explanation:

When referring to a reciprocal, it basically means taking the numerator and the denominator and flipping them.

For example, take 4/5. The reciprocal of 4/5 would be 5/4.

Now, take 5. As a fraction, it would look like 5/1. If you were to flip it, it would be 1/5.

Therefore, the reciprocal of 5 is 1/5.

Answer:

The correct option is;

B) C(A(x))

Step-by-step explanation:

The given information are;

The cost to install the floor per square foot = $9

The area of the room is given by the function A(x) = x²

The function for the cost per square foot = C(A) = 9·A

We note that the total cost to install the wood floor = (The cost to install the floor per square foot) × (The area of the room)

∴ The total cost to install the wood floor = $9 × x²

Given that A(x) = x², we have;

The total cost to install the wood floor = $9 × A(x)

Also, given that C(A) = 9·A, we have;

C(A(x)) = 9·A(x)

Therefore;

The total cost to install the wood floor in dollar amount can be given by the function, C(A(x)) = 9·A(x)

math

Answer:

8x+161

Step-by-step explanation:

Let, total number of T-shirts are x.

Number of blue T-shirts = (2/3)x = 2x/3 .

Number of blue shirts on sale = (3/5)(2x/3) = 2x/5 .

Number of medium sized blue shirts on sale = (1/5)(2x/5) = 2x/25 .

Fraction of the​ shop's T-shirts are blue​ T-shirts that are on sale and are size​ medium = [tex]\dfrac{2x/25}{x}[/tex]= 2/25 . ( Number of medium sized blue shirts on sale divided by total number of T-shirts )

Hence, this is the required solution.

Hello,

odd + odd gives even

odd + even gives odd

so odd + odd + even + odd = even + even + odd = even + odd = odd

So the sum is a odd number

thanks

The sum of three odd numbers is odd and that added to an even number results in an odd number.

An even number raised to the even or odd power is even and an odd number raised to the power of even or odd is always an odd number.

We know the sum of two even numbers is even, the sum of two odd numbers is also even and the sum of an odd and even number is odd and vice versa.

Given four numbers first two numbers are odd so their sum is even.

The next two numbers are even and odd so their sum is odd, Now the sum of even and odd is odd.

Answer:

Step-by-step explanation:

Teacher bought $21 worth of stickers and cardstock for his class.

Cost of stickers = $1.50 per sheet

Cost of 's' sheets = $1.5s

Cost of cardstock = $3.50 per pack

Cost of 'c' packs = $3.5c

Equation representing the relationship between sheet of stickers and packs of cardstocks will be,

1.5s + 3.5c = 21

3.5c = -1.5s + 21

1). [tex]c=-\frac{3}{7}x+6[/tex]

   y-intercept of the line → (0, 6)

   x-intercept of the line → (14, 0)

   Therefore, equation of the line represents the line on the graph.

2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.

   Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.

Answer: c

Step-by-step explanation:

A full circle is 360 degrees so half way would be 180 and since theyre parallel you know that you can use the 55 degrees up top to use in ur equation to find cfe

180-55=125

Can't be 45 because the angle on the other side is smaller than cfe and its 55 degrees and cfe has to be wider than 90 degrees because a right angle is 90 degrees and this angle noticeable goes past 90

Can't be 180 because the whole thing equals 180
