A store sells six cupcakes for $7. How much do 18 cupcakes cost?

Answers

Answer:

21 cupcakes

Step-by-step explanation:

6 = $7

A solid is formed by adjoining two hemispheres to the ends of a right circular cylinder. The total volume of the solid is 14 cubic centimeters. Find the radius of the cylinder that produces the minimum surface area. (Round your answer to two decimal places.)

Answers

Answer:

Step-by-step explanation:

V = 4πR³/3 + πR²h

h = (V - 4πR³/3) / πR²

A =  4πR² + 2πRh

A =  4πR² + 2πR((V - 4πR³/3) / πR²)

A =  4πR² + 2((V - 4πR³/3) / R)

A =  4πR² + 2V/ R - (8πR³/3) / R

A =  4πR² + 2(14)/ R - 8πR²/3

A =  (4π - 8π/3)R² + 28/R

A =  (4π/3)R² + 28/R

dA/dR = (8π/3)R - 28/R²

       0 = (8π/3)R - 28/R²

28/R² = (8π/3)R

     R³ = 28(3 / 8π)

      R = 1.49513...

      R = 1.50 cm

which makes the cylinder height 0.00 cm. The figure is a sphere.

Alright I’ll go in order

Well first things first I’m gonna make the numbers in order first to make life easier

22, 36, 39, 39, 40, 40, 41, 42, 45, 46, 46, 49

#1: Is asking for the median of the data

The median is basically the center of the data in order

In this case the middle number here is 40 and 41, we jsut find the average between those 2 to find it. 40+41= 81 81/2= 40.5

Median :40.5

#2: Is asking for the mode

The mode is the number that comes up or repeats the most.

in this case it’s 39, 40, and 46

Mode: 39, 40, 46

#3: Is asking for the mean

The mean is basically the average, you add up all the given numbers and divide it by the amount of numbers there are. In this case it goes something like

22+36+39+39+40+40+41+42+45+46+46+49

you would get 446

Now theres 12 numbered so we divide that by 12

446/12 you’d get 37 1/6 as ther average or 37.166666666666…

#4: Is asking for the range

You just find the difference ebetween the greatest number and llowest number. In this case it’s 49-22 so you got 27

Range: 27

I think you can figur the rest out on your own!

Answer:

  D. choosing first second-, and third-place winners in a cooking contest​

Step-by-step explanation:

His old house was 21.45 miles from the office. He moves to a new apartment which is just 3.65 miles from the office.

Since it asks for the distance he reduced to the office, we would do

21.45 - 3.65 = 17.8 miles

In 1912, Alfred Wegener proposed the theory of continental drift, stating that all the continents were once joined together and slowly moved apart. However, his theory was not widely accepted in his time.
