Answer:

x = 50

Step-by-step explanation:

3x - 10 and 2(x + 10) are vertical angles and congruent , so

3x - 30 = 2(x + 10)

3x - 30 = 2x + 20 (  subtract 2x from both sides )

x - 30 = 20 ( add 30 to both sides )

x = 50

The first row of a theater has 16 seats. There are 3 more seats in each row thereafter. How many seats are in the 25th row/

Answers

Answer: 88

Step-by-step explanation:

Given

The first row has 16 seats

then there are 3 more seats in each row

this follows an AP with the first term [tex]a=16[/tex] and common difference [tex]d=3[/tex]

So, no of seats in the 25 th row is

[tex]\Rightarrow a_{25}=a+24d\\\Rightarrow a_{25}=16+3\times 24\\\Rightarrow a_{25}=88[/tex]

Thus, there are 88 seats in the 25 th row

The lateral area of a cylinder is 100pi in^2. If its dimensions are reduced to one-fifth their original length, what would its new area be?

Answers

Answer:

4pi in^2

Step-by-step explanation:

Lateral surface area of a cylinder = 2πrh

π = pi

r = radius

h = height

Let me illustrate with an example

A cylinder has the following dimensions

r = radius = 20  

h = height  = 10

lateral area = 2 x π x 20 x 10 = 400π

If dimensions are reduced to one-fifth their original length, new dimensions are

r = radius = 20  x 1/5 = 4

h = height  = 10 x 1/5 = 2

New lateral area = 2 x 4 x 2 x π = 16π

change in lateral area = 400π / 16π = 25

If dimensions are reduced by 1/5, lateral area would reduce by 25

100 pi / 25 = 4
