step by step

Step-by-step explanation:

where

r = radius

h= height

Area of a cylinder = 2πrh+2πr^2

Area of a cylinder = 2π8(3)+2π8^2

Area of a cylinder = 176π = 552.92

Area of a hemisphere= 3r2π

Area of a hemisphere= 3(2)2π

Area of a hemisphere= 12π = 37.699111843

Area of the cylinder in this problem

176π - 12π = 164π

The demand function for a product is modeled by p = 400 − 4x, 0 ≤ x ≤ 100, where p is the price per unit (in dollars) and x is t

lawyer [7]

Answer:

Demand is Elastic when Price > 200 ; Demand is inelastic when Price < 200

Step-by-step explanation:

p = 400 - 4x

4x = 400 - p

x = (400 - p) / 4 → x = 100 - p/4

Elasticity of demand [ P ed ] = (Δx / Δp) x (p / x)

Δx / Δp [Differentiating x w.r.t p] = 0 - 1/4 → = -1/4

P ed = <u>-1</u> x<u> p </u>

4 (400 - p)/4

= <u>-1</u> x <u> 4p </u> = -p / (400-p)

4 (400 - p)

Price Elasticity of demand : only magnitude is considered, negative sign is ignored (due to negative price demand relationship as per law of demand).

So, Ped = p / (400 - p)

Demand is Elastic when P.ed > 1

p / (400-p) > 1

p > 400 - p

p + p > 400 → 2p > 400

p > 400 / 2 → p > 200

Demand is inelastic when P.ed < 1

p / (400-p) < 1

p < 400 - p

p + p < 400 → 2p < 400

p < 400 / 2 → p < 200

The factory workers made 715 toys per day if they work five days per week how many toys well the workers make in three weeks

Furkat [3]

Is this too old? um 715 toys per day times 5 equals 3575. 3575 times 3 is <span>10725. so the workers will make 10725 toys in 3 weeks.</span>

monarch butterflies migrates when they sense daylight hours are shorter and temperature get colder.write two equivalent fraction

Tpy6a [65]

Two equivalent fractions to represent the part of the migration a monarch butterfly can complete in 1 week is $\frac{5}{25}$ or $\frac{1}{5}$ .

<h3>What is a fraction?</h3>

A fraction is a mathematical expression that shows the relationship between parts vs total. In a fraction, the part is written first and it is known as the numerator. On the other hand, the total is written below and it is known as the denominator.

<h3>How to write a fraction?</h3>

Here are the steps to write a fraction:

Find the total.
Find the part.
Write the fraction.

Based on this, in the chart, the part of the migration these butterflies can complete in a week are the squares in green, while the total is the total squares. This means the fraction for this situation is:

$\frac{5}{25}$

Moreover, you can simplify this fraction and find an equivalent one by dividing the denominator by the numerator as:

$\frac{1}{5}$
