The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³

Volume is the amount of space occupied by a three dimensional object or figure.

The cup has the shape of a cylinder, the volume is:

Volume = π * radius² * height

For cup A:

Volume = π * (10/2)² * 20 = 1570.8 cm³

Let each punch be 1 cm³, the number of cups needed = 1570.8 cm³ / 1 cm³ = 1571

For cup B:

Volume = π * (20/2)² * 20 = 6283 cm³

Let each punch be 1 cm³, the number of cups needed = 6283 cm³ / 1 cm³ = 6283

The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³

Answer:

-21

Step-by-step explanation:

Each of those lines is -3
If you look at the -10, it goes down 2 lines and goes to -16 meaning that if it only went down one line it would only go to -13

Showing that each line is worth -3

It goes down 2 lines from -16 (-6)

so if you go down 6 from -16 that would get you to -21

The answer is: -18

That is because, on the number line, they already have 2 numbers. They are -10 to -16. To go from -10 to -16, you subtract 2. Since the mark is the same distance away as -10 to -16 on this number line, you would subtract  2 from -16, which would be -18.

Answer:

f(2) = -3

Step-by-step explanation:

Find f(2) given f(x) = 2x^2 + 5x - 21​

Since on the left side, x is replaced by 2, on the right side, x should also be replaced by 2.

f2 = 2(2)² + 5(2) - 21

2 x 2² = 2 x 4 = 8

5 x 2 = 10

8 + 10 = 18

18 - 21 = ?

-(21 - 18 = 3)

-21 + 18 = -3

f(2) = -3

Considering the given angle and the given formula, it is found that the percentage error for an angle of 0.02 radians is of 0.0067%.

For an angle [tex]\theta[/tex], it is given by the following formula:

[tex]P = 100\frac{|\sin{\theta} - \theta|}{\sin{\theta}}[/tex]

In this problem, the angle is of [tex]\theta = 0.02[/tex], hence:

[tex]P = 100\frac{|\sin{0.02} - 0.02|}{\sin{0.02}}[/tex]

[tex]P = 0.0067[/tex]

The percentage error for an angle of 0.02 radians is of 0.0067%.

Answer:

Step-by-step explanation:

Use the formula for area of a circle

A = [tex]\pi r^{2}[/tex]

The diameter is 8ft, if there was only a line from the middle to the edge of the circle, then it would be radius

The radius is half the diameter so divide 8 by two and you get the radius

Plug in the radius into the formula

A = [tex](4ft)^{2} \pi[/tex]

the parenthesis indicate you aren't only squaring the ft, but also the 4

4ft * 4ft = 16[tex]ft^{2}[/tex]

(remember you are also multiplying the unit, in this case feet)

A = [tex]16ft^{2} \pi[/tex]

there aren't parenthesis here, meaning you aren't squaring the 16

A = 50.24[tex]ft^{2}[/tex]

Sam eats the melon in 0.2 minutes.

John eats the melon in 2.2 minutes.

x - y = 2 equation 1

x + y = 2.4 equation 2

Where:

x = minutes John eats the melon

y = minutes Sam eats the melon

Add equation 1 and equation 2 together

2x = 4.4

Divide both sides by 2

x = 2.2

Substitute for x in equation 1

2.2 - y = 2

y = 2.2  2

y = 0.2 minutes

Answer:

x=2

Step-by-step explanation: 1.2x-5.2=-2.4x+2. First, you add 2.4x to 1.2x to get x isolated. So now it's 3.6x-5.2=2. Then add 5.2 to 2 to isolate x. Now you have 3.6x=7.2 now you divide 7.2 by 3.6 to get x=2.

Answer:

x=2

Step-by-step explanation:

1.2x-5.2=-2.4x+2

multiply 10

12x-52=-24x+20

refine and add 52

12x=-24x+72

add 24x

36x=72

Let's imagine all the tickets were for children.

The fees collected would've been 342 x 1.25 = $427.5

That is 1337 - 427.5 = $909.5 less than the actual fees.

Everytime we switch 1 children ticket to an adult ticket, the gap goes down 6.60 - 1.25 = 5.35

For example, if 341 tickets were children tickets, and 1 is adult, the gap go from 909.5 to 904.15.

We do this until the gap becomes 0... So, there are 909.5 : 5.35 = 170 adult tickets

And there are 342 - 170 = 172 children tickets


Recheck : 172 x 1.25 + 170 x 6.6 = 215 + 1122 = 1337.
