find the surface area of a cylinder with height of 8 feet and base diameter of 6 feet
Answer:
[tex]66\pi[/tex] ft²
Step-by-step explanation:
First find the area of the rectangle surrounding the cylinder.
Since the base diameter is 6 feet, the circumference [tex]=\pi d=6\pi[/tex].
Since the height is 8 feet, the area of the rectangle is [tex]6\pi\times8[/tex] or [tex]48\pi[/tex]
Now the area of the base circle [tex]=\pi r^2 = \pi\times\frac{1}{4}d^2=9\pi[/tex]
There are 2 base circles, so [tex]9\pi\times2=18\pi[/tex]
Surface area = [tex]18\pi+48\pi=66\pi[/tex] ft²

a history book weights 24 oz more than a math book. the marh book is 75% the weight of the history book. how much does each book weight
The weight of the math and the history book are 72 and 96 ounces respectively.
How to find the weight of a book?A history book weights 24 oz more than a math book.
Therefore,
let
x = weight of math book
weight of history book = 24 + x
The math book is 75% the weight of the history book.
Therefore,
math book weight = 75 / 100 (24 + x)
x = 75 / 100 (24 + x)
x = 1800 + 75x / 100
100x = 1800 + 75x
100x - 75x = 1800
25x = 1800
x = 1800 / 25
x = 72
Therefore,
weight of math book = 72 ounces
weight of history book = 72 + 24 = 96 ounces.

Use the table to the right to answer the following question.
Compare the energy released by fission of 1 kilogram of element B to that released by burning 1 kilogram of element A.
Fission of 1 kg of element B releases 2941 times as much energy as burning 1 kg of element A
How to compare the energy released?The given parameters are:
Energy A = 5.1 * 10^7
Energy B = 1.5 * 10^11
The amount of energy B in proportion to energy A is calculated as
Proportion = Energy B/Energy A
So, we have:
Proportion = (1.5 * 10^11)/(5.1 * 10^7)
Divide 1.5 by 5.1
Proportion = 0.2941 * 10^11/10^7
Divide 10^11 by 10^7
Proportion = 0.2941 * 10^4
Evaluate
Proportion = 2941
Hence, fission of 1 kg of element B releases 2941 times as much energy as burning 1 kg of element A

Deepak is choosing a password for his phone using letters from the alphabet, A-Z. The password must be four letters long, and he can repeat letters. How many different passwords can he create?
Answer: 26 × 4
Step-by-step explanation: There are 26 letters in the alphabet lettered A through Z.
Deepak is given the choice of picking a four letter password of his liking, using any four letters. Since the letters he uses can be repeated, it is 26 * 4 possibilities, since there are 26 different possibilities of letters from the alphabet he could choose, for 4 times. Also, since letters can be repeated, 26 stays the same. If letters could not be repeated, it would be 26 * 25 * 24 * 23.
Answer:
B. 26⁴
Step-by-step explanation:
If the password is 4 letters long and he can repeat letters then:
1st letter: any one of the 26 letters from the alphabet2nd letter: any one of the 26 letters from the alphabet3rd letter: any one of the 26 letters from the alphabet4th letter: any one of the 26 letters from the alphabetTherefore, to find the total number of passwords he can create, simply multiply the number of permutations for each letter of his password:

A company in its first year of business produced 150 training manuals for a total cost of $2.350. The following
year, the company produced 50 more manuals at a cost of $ 1,450. Use this information to find a linear equation
that gives the total cost of producing training manuals from the number of manuals produced.
Answer:
y = 9x +1000
Step-by-step explanation:
The relation for the total cost of manuals based on the number produced will be the sum of a base cost and a variable cost. The variable cost is the product of the cost per manual and the number of manuals.
Cost per manualThe cost per manual can be found by looking at the increase in cost relative to the increase in the number of manuals produced:
cost per manual = (increase in cost)/(increase in production)
= ($2350 -1450)/(150 -50) = $900/100 = $9
Base costThe base cost will be added to the product of the cost per manual and the number of manuals. For the 2nd year purchase, this is ...
$1450 = base cost + (50 manuals)×($9/manual)
$1450 = base cost + $450
base cost = $1450 -450 = $1000
EquationThe equation for the cost in dollars (y) of producing x manuals can now be described by ...
y = (cost per manual)x +(base cost)
y = 9x +1000
You want to buy a $33,000 car. The company is offering a 3% interest rate for 36 months (3 years). What will your monthly payments be?
Answer:
$959.68
Step-by-step explanation:
The loan amortization formula can be used to find the payment amount.
FormulaA = P(r/n)/(1 -(1 +r/n)^(-nt))
A = payment amount; P = principal borrowed; r = annual interest rate; t = number of years; n = payments per year (and number of times interest is compounded per year).
ApplicationFor a principal amount of $33,000 at an interest rate of 3%, the 36 monthly payments will be ...
A = $33000(0.03/12)/(1 -(1 +0.03/12)^(-12·3)) ≈ $959.68
The monthly payments will be $959.68.

The question was incomplete. Below you will find the missing content.
Use the system of equations and graphs below to complete the sentence.

The graph that correctly represents the given system of equations is a graph ( ), and the solution to the system is ( , ).
The correct option will be Option B: Graph B and the solution of the given system of equations will be (3,-1).
Given the first equation is x-2y=5
in this equation of line, the x-coordinate is:
x-(2.0)=5

in this equation of line, the y-coordinate is:
0- 2y=5
⇒y= -5/2
The y-coordinate will be (0,-5/2).
So the first line equation has x-coordinate (5,0) and y-coordinate (0,-5/2).
Similarly,
Given the second equation is 3x+15y=-6
in this equation of line, the x-coordinate is:
3x+(15.0)=-6
⇒ x=6/3=2
The x-coordinate will be (2,0).
in this equation of line, the y-coordinate is:
(3.0)+15y=-6
⇒y= -6/15= -2/5
The y-coordinate will be (0,-2/5).
So the second line equation has x-coordinate (2,0) and y-coordinate (0,-2/5).
Equation-1: x - 2y = 5
⇒x =2y+5
putting the value of x in equation-2
3x + 15y = -6
⇒ 3(2y+5)+15y=-6
⇒6y+15+15y=-6
⇒21y=-6-15=-21
⇒y=-21/21=-1
putting the value of y in equation of x
x= 2(-1)+5= -2+5= 3
The solution of system of equations will be (3,-1)
Checking all the options
In option B one line has x-coordinate (5,0) and y-coordinate (0,-5/2) and another line has x-coordinate (2,0) and y-coordinate (0,-2/5).
And the point of intersection of two lines is (3,-1).
