We should choose mug 1 having volume of  71.24 inch³ ,with diameter 5.5 inches and height 3 inches holds the most !

<u>Step-by-step explanation:</u>

We have 2 mugs, One has a base that is 5.5 inches in diameter and a height of 3 inches. The other has a base of 4.5 inches in diameter and a height of 4 inches. Basically, mugs are cylinders so we will consider 2 cylinders .

To find which one holds the most we are supposed to find volume of both ,the one with maximum volume holds the most.

<u>Part 1: </u>

volume of cylinder 1 (V_{1})= πr₁²h₁ ,

r₁ = radius of cylinder ⇒ \frac{\text {diameter}}{2}=\frac{5.5}{2}=2.75 \text { inches }

h₁ = height of cylinder ⇒  3 inches

∴ V_{1} = πr₁²h₁

⇒ 3.14×( 2.75 )²×3 ⇒ 71.24 inch³

<u>Part 2:</u>

volume of cylinder 2 ( V_{2} )= πr₂²h₂

r₂ = radius of cylinder ⇒ \frac{\text {diameter}}{2}=\frac{4.5}{2}=2.25 \text { inches }

h₂ = height of cylinder ⇒  4 inches

∴ V_{2} = πr₂²h₂

⇒ 3.14×( 2.25 )²×4 ⇒ 63.59 inch³

∵ V_{1} ( 71.24 inch³ ) > V_{2} ( 63.59 inch³ ), mug 1 with diameter 5.5 inches and height 3 inches holds the most.

In his first year, a math teacher earned $32,000. Each successive year, he
Ivan

Answer:

Step-by-step explanation:

Each successive year, he

earned a 5% raise. It means that the salary is increasing in geometric progression. The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence(amount earned in the first year).

r represents the common ratio.

n represents the number of terms(years).

From the information given,

a = $32,000

r = 1 + 5/100 = 1.05

n = 20 years

The amount earned in his 20th year, T20 is

T20 = 32000 × 1.05^(20 - 1)

T20 = 32000 × 1.05^(19)

T20 = $80862.4

To determine the his total

earnings over the 20-year period, we would apply the formula for determining the sum of n terms, Sn of a geometric sequence which is expressed as

Sn = (ar^n - 1)/(r - 1)

Therefore, the sum of the first 20 terms, S20 is

S20 = (32000 × 1.05^(20) - 1)/1.05 - 1

S20 = (32000 × 1.653)/0.05

S20 = $1057920

1/4, because you disregard the repeating 25s and round, and 25 x 4 is one hundred, so simplified it's 1/4.

In a class of 40 students, 5 like neither Nokia nor
STatiana [176]

Answer:

<em><u>The number of students that like only Nokia </u></em>

<h2>= 30</h2>

Step-by-step explanation:

consider N the number of students who like Nokia → N=?

               T the number of students who like Techno → T=35

Statement 1: In a class of 40 students, 5 like neither Nokia nor Techno

we can translate it like this: 35 student like Nokia or Techno

we can note it like this : T∪N= 35

Statement 2: 30 like Techno and Nokia

we can note it : T∩N = 30

using a rule concerning the number of element of a set :

T∪N = N + T - T∩N

then

35 = N + 35 - 30

⇒ N - 30 = 0

⇒ N = 30
