Answers

Answer 1

Hi, sorry for a late response, but here are the answers if they are still helpful?

The volume would be about 4,188.79

(if rounded and if not the answer is below and so is the work.)

Volume = 4

—— πr3

3

= 4

—— ✖️ π ✖️ 103

3

= 4188.7902047864 centimeters^3

The surface area would be about 1,256.64

(if rounded and if not the answer is below and so is the work.)

Surface Area = 4πr2

= 4 × π × 102

= 400π

= 1256.6370614359 centimeters^2

Answer 2
I believe it’s 4,188.79. I’m not sure

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

The given decimal numbers are $18.75 and $18.60.

We know that, percentage change = (Original price-New price)/Original price ×100

= (18.75-18.60)/18.75 ×100

= 0.15/18.75 ×100

= 0.008×100

Answer:

Step-by-step explanation:

You haven't given the choices but I believe the equation below could represent the area of the circle:

(pi ~ 3.14) * (18)^2

The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

Lauren has a points card for a movie theater.
She receives 60 rewards points just for signing up.
She earns 5.5 points for each visit to the movie theater.
She needs 104 points for a free movie ticket.

Write and solve an equation which can be used to determine xx, the number of visits Lauren must make to earn a free movie ticket.

Answers

Multiply points per visit x number of visits, using x for the number of visits:

5.5x

Add that to the points she already has:

5.5x + 60

This needs to equal a total of 104 points:

5.5x + 60 = 104

Now solve for x

5.5x + 60 = 104

Subtract 60 from both sides

5.5x = 44

Divide both sides by 5.5

X = 8

She needs 8 more visits

the answer is 5.5x+60=104

connor found out that 60% of 40 is the same as 25% of the number n. what is the value of n?

Answers

Answer:

96

Step-by-step explanation:

Step 1: Multiply 60% by 40

40 x .60 = 24

24 is 60 percent of 40

Step 2: If 24 was 25% of n, then we have to divide 100 by 25 to see how much we have to multiply 24 by.

100 ÷ 25 = 4

Step 3: Multiply 4 by 24

4 x 24 = 96

A mirror frame in the shape of an oval is shown below. The ends of the frame form semicircles:

192.78 inches
246.78 inches
277.56 inches
331.56 inches

please help lol

Answers

Answer:

The answer is 192.78 inches

Step-by-step explanation:

An oval is formed by a rectangle with semicircles at each end. We can visualize this easily.

The length of the rectangle is 54 inches.

The width of the rectangle is 27 inches.

The perimeter of rectangle is =  

=  

= 162 inches

And because there are two semicircles, we can combine them to form a circle. So, perimeter of a circle is called a circumference.

The width of the rectangle forms the diameter, so its half will be the radius.

r =  

The circumference is given by :  

=  inches

Now as the described oval shape is a complete figure without lines inside, we will subtract the width of both sides of the rectangle from the complete perimeter.

The complete perimeter is =  inches

The inner edge perimeter will be =  = 192.78 inches
