A=2πrh+2B solve for b
Answer:
b = [tex]\frac{A-2\pi rh}{2}[/tex]
Step-by-step explanation:
Given
A = 2πrh + 2b ( subtract 2πrh from both sides )
A - 2πrh = 2b ( divide both sides by 2 )
[tex]\frac{A-2\pi rh}{2}[/tex] = b

14, Melanie began with 14 books.
Step-by-step explanation:
If we think the answer is 14, and she gets rid of half she has 7 left. If she buys 7 more she has 14 again. So the answer is 14 not 7, so sorry!
If you want I can try again with a different example.

Additive Inverse Property
0 = 5c +
what is the missing number?
Answer:
Hi there!
Your answer is:
-5c
The full equation is:
0= 5c + (-5c)
Step-by-step explanation:
The additive inverse is whatever two numbers, when added, equal 0. We have a positive 5c here. To get rid of 5c, we must subtract 5c from 5c
I hope this helps!
Answer:
(-5c)
Explained,
0 = 5c + (-5c)
0 = 5c - 5c
= 0

A man sold two computers for Rs. 24,000 each. On one
he gained 20% and on the other, he lost 20%. Find his gain
or loss percentage of his whole transaction.
Answered
Sale price of first computer = Rs 24000
gain = 20%
So cost of first computer = 100/120 x 24000 = Rs 20,000
Sale price of second computer = Rs 24000
Loss 20%
So cost of second computer = 100/80 x 24000 = Rs 30,000
Total cost = Rs 50,000
Total sale value = Rs 48000
Loss = Rs 2000
Loss % = 2000/50000 x100= 4 % LOSS ANSWER

4, 2, 1
d.
-4, 2, -1
Answer:
the answer is d.
Step-by-step explanation:
each variable is being divided by negative two.

2/-2 = -1
If Ivy makes $50 each week mowing lawns. She estimates that she will
have to spend $120 this summer of gas for the mower. If Ivy wants to
earn $480 this summer, how many weeks must she work?
Answer:
12 weeks
Step-by-step explanation:
The equation is 50*x-120=480
We have to find out what x equals
50*12=600
600-120=480

O nas
On=0
Answer:
[tex]n=\frac{189}{104}[/tex]
Step-by-step explanation:
7−2(8n−3)=4(n−2)(22)
Step 1: Simplify both sides of the equation.
7−2(8n−3)=4(n−2)(22)
7+(−2)(8n)+(−2)(−3)=88n+−176(Distribute)
7+−16n+6=88n+−176
(−16n)+(7+6)=88n−176(Combine Like Terms)
−16n+13=88n−176
−16n+13=88n−176
Step 2: Subtract 88n from both sides.
−16n+13−88n=88n−176−88n
−104n+13=−176
Step 3: Subtract 13 from both sides.
−104n+13−13=−176−13
−104n=−189
Step 4: Divide both sides by -104.
[tex]-\frac{104n}{104} =-\frac{189}{104} \\n=\frac{189}{104}[/tex]
Answer:

Ray UW is the angle bisector of Angle VUT. If the measure of Angle VUW = (4x + 6)° and the measure of Angle WUT = (6x – 10)°, what is the measure of Angle WUT?
Hello! :)
Answer:
[tex]\huge\boxed{38^{\circ}}[/tex]
--------------------------------------------------------------------------
An angle bisector divides an angle in half, therefore:
m∠VUW ≅ m∠WUT
Set the expressions equal to each other:
4x + 6 = 6x - 10
Subtract 4x from both sides:
6 = 2x - 10
Add 10 to both sides:
16 = 2x
Divide 2 from both sides:
x = 8.
Substitute in the value of "x" into the equation for ∠WUT:
6(8) - 10 = 48 - 10 = 38°.
Factor completely 5x^2-5x - 100.

The yearbook club has 5 members returning from last year. They set up a booth in the cafeteria to recruit more members, and an average of 3 new members sign up each day. Which best describes why the graph relating the total number of members on the yearbook club, m, and the number of days the booth is set up, d, will be continuous or discrete?
The graph will be continuous because an end day for the booth being set up is not given in the description.
The graph will be continuous because there can be any number of people signing up each day since we are only given the average.
The graph will be discrete because some day the number of available people to sign up for the club will run out.
The graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
The correct option is the graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
What is Discrete Random Variable?Discrete random variables are defined as the variable which takes only finite number of distinct values in the data set.
These variables are usually countable.
Continuous random variables are those which take infinitely many values in the data set.
These include all set of real numbers.
Here the situation is the recruitment of members for the yearbook club.
The members coming for sign up will only in the form of numbers like 0, 1, 2, 3, ........
There is nothing like partial person coming for the sign up.
And there will be only finite number of members each day because booth is set up only once in each day.
Hence the graph of total number of members on the yearbook club, m, and the number of days the booth is set up, d, will be discrete.

What is the domain of the function
Answer:
A domain is the possible x-values in a ordered pair or an input value in a table
Step-by-step explanation:
I learned this by reading a lesson about it.
Also, here are some additional tips given from me to any of you when writing a domain or range!
When you write a domain or range:
1. List the numbers separated by commas instead of braces (if it is listed in braces and not in a table or ordered pair)
2. List the value(s) from least to greatest
Note: Duplicate numbers listed in an table or braces should only be listed once.

What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The distance between two coordinates (x₁,y₁) and (x₂,y₂) are given by
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
