Answers

Answer 1

Answer:

See answers below

Step-by-step explanation:

Entire outer circle area = pi r^2   = pi 18^2 =  324 pi cm^2

   if you subtract the small unshaded circle you get 299 pi

    324 pi  - smaller circle = 299 pi

      smaller circle = 25 pi  cm^2

of colored beads six times. If the length of
one pattern measures three fourths of an
inch in length, what is the total length of
the bracelet Sofia made?

Answers

Answer:

11.424cm

Step-by-step explanation:

3/4 of an inch = length of one pattern.

3/4 = 0.75 ( 1.905cm)

1.905 x 6 = 11.424cm

The total length of the bracelet Sofia made is 11.424 centimetres.

30. Tina went to batting cages with $20. She rented a bat for $3. 25 and

paid $3 for each round. What was the greatest number of rounds Tina

could have played?

Answers

Answer:

5

Step-by-step explanation:

Tina started with $20, but had to spend $3.25 on the bat.

$20-$3.25 = $16.75, which is all she has left for rounds.

Each round costs $3.00

$16.75 divided by $3.00 comes out to 5.58 rounds, but since she can't play 1/2 a round, that means she could only play 5 rounds

5 rounds X $3.00 per round comes to $15.00

Answers

You first need to rearrange your equation to make it equal one variable. So I isolated x which gives me x=-1(y^2-4). You then put the X equation into the first equation. Which gives (-y^2+4)^2-y^2=16. The answer when you solve for y is 0. You then substitute y in the second equation. Which gives 0=-x+4 then solve for x. The answer being x=4 and y=0

1000x+27x+5.5=9236



​

Answers

Answer:

x = 8.98782862707

Step-by-step explanation:

Base on the given we can infer that we are solving for x:

Given equation:

1000x+27x+5.5=9236

Combine similar terms

1027x + 5.5 = 9236

Subtract both side by 5.5

1027x + 5.5 = 9236

             -5.5      -5.5

-------------------------------------

1027x = 9230.5

Now divide both sides by 1027x

9230.5 / 1027

x = 8.98782862707

What is a rectangular prism?

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangle surface.

What is a cylinder?

A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

A square prism has a height of 12 inches and a base with an area of 30 square inches.

A cylinder is inscribed inside the prism.

The volume of the square prism will be

[tex]V_{square} =Base[/tex] [tex]area*Height[/tex]

[tex]V_{square}=30*12[/tex]

[tex]V_{square} =360[/tex] [tex]in^3[/tex]

The volume of the cylinder will be

[tex]V_{cylinder}=\pi r^2h[/tex]

The radius of the base circle of the cylinder will be

[tex]r=\frac{\sqrt[]{30}}{2}[/tex]

[tex]r=2.7386[/tex]

Then volume will be

[tex]V_{cylinder}=\pi *(2.7368)^2*12[/tex]

[tex]V_{cylinder}=282.74[/tex] [tex]in^3[/tex]

The volume of the cylinder (282.74 in.³) is less than the volume of the square prism (360 in.³). Then the correct option is C.
