Answer:
2/3
Step-by-step explanation:
h = height of the cone
Vcone = πr²h/3
H = h/2 = height of the cylinder
Vcylinder = πr²H = πr²h/2
Vcone/Vcylinder = (πr²h/3)/(πr²h/2)
= πr²h/3 x 2/πr²h
= 2/3
Answer:
2/3
Step-by-step explanation:
h = height of the cone
Vcone = πr²h/3
H = h/2 = height of the cylinder
Vcylinder = πr²H = πr²h/2
Vcone/Vcylinder = (πr²h/3)/(πr²h/2)
= πr²h/3 x 2/πr²h
= 2/3
im2 finding angles using algebra
find: m<BEC
Answer:
m<bec = 60
Step-by-step explanation:
3x +2x +x = 180 (combine like terms)
6x = 180 (divide 180 by 6 to get x alone on one side of the equation)
x = 30
BUT you're not done yet because it asked for m<bec which is 2x so you have to multiply 30(2) which is 60

6 + ( - 3 ) is ___ units from 6, in the ___ direction.
Answer:
6+(-3) is 3 units from 6 in the right direction
Step-by-step explanation:
6 + ( - 3 ) is 3 units from 6, in the right direction.
What are integers?An integer is the number zero, a positive natural number or a negative integer with a minus sign. The negative numbers are the additive inverses of the corresponding positive numbers.
Given:
6 + ( - 3 ) is ___ units from 6, in the ___ direction.
as we know that 6 +(-3) = +3 units
So, -3 is 3 units away but the direction depend on the sign between the numbers.
Then, according to the sign the direction is on right side.
Hence, 6 + ( - 3 ) is 3 units from 6, in the right direction.

Solve for c .
A(c+b)=d
answer choices are in the pic
Answer:
A(c+b)=d.
Ac+Ab=d.
Ac=d-Ab.
Divide through by A.
c=d-ab/a.
Option A.
Steps to solve:
a(c + b) = d
~Distribute
ac + ab = d
~Subtract ab to both sides
ac = d - ab
~Divide a to both sides
c = d-ab/a (Option 1)

2.) why isn’t -25 a whole number?
Which of the following equations have exactly one solution?
Choose all answers that apply:
A. −5x+12=−12x−12
B. −5x+12=5x+12
C. −5x+12=5x−5
D. −5x+12=−5x−12
Answer:
A, B, & C
Step-by-step explanation:
A: -5x +12 = -12x - 12
+12x +12x
7x + 12 = -12
-12 -12
7x = -24 [Divide both sides by 7 to get x]
x = -24/7
B: −5x + 12 = 5x + 12
-5x -5x
-10x + 12 = 12
-12 -12
-10x = 0 [Divide both sides by -10 to get x]
x = 0
C: −5x + 12 = 5x − 5
-5x -5x
-10x + 12 = -5
-12 -12
-10x = -17 [Divide both sides by -10 to get x]
x = 17 / 10
D: −5x + 12 = −5x − 12
+5x +5x
12 ≠ -12 [The statement is false, so it isn't the correct answer]

Tina and her friends want to go bowling. Family Bowling Alley charges $1 for shoes and $4 dollars per game. Knight Owl Bowling charges $2 for shoes and $3.75 per game. How many games will it take for the cost of bowling at each alley be the same?
Answer:
Number of games = 4
Step-by-step explanation:
Let the number of games = x
Family Bowling Alley charges $1 for shoes and $4 dollars per game
If x games is played
Cost= 1+4(x)
Knight Owl Bowling charges $2 for shoes and $3.75 per game.
If x games is played
Cost = 2 + 3.75(x)
When the both cost are equal
1+4(x)= 2+3.75(x)
4x-3.75x = 2-1
0.25x = 1
X= 1/0.25
X= 4
Number of games = 4

It takes a bus 6 hours to take a trip. The train takes only 4 hours to make the same trip. The train travels at a rate of speed that is 25 mph more than the speed of the bus. What is the rate of the bus and the rate of the train? State what x represents, state the equation, and then state the answer.
Answer:
x represents the trip distance.
x = 300 miles
Rate of bus = 50 mph
Rate of train = 75 mph
Step-by-step explanation:
Let the trip distance be x miles.
[tex] \because \: speed = \frac{distance}{time} \\ time \: taken \: by \: bus \: to \: complete \: \\ the \: trip \: = 6 \: hours \\ \therefore \: speed \: of \: bus = \frac{x}{6} \: mph \\ \\ time \: taken \: by \: train \: to \: complete \: \\ the \: same \: trip \: = 4 \: hours \\ \therefore \: speed \: of \: train = \frac{x}{4} \: mph \\ \\ \because \: \: speed \: of \: train \\ =speed \: of \: bus \: + 25 \: mph \\ \therefore \: \frac{x}{4} = \frac{x}{6} + 25 \\ \\ \therefore \: \frac{x}{4} - \frac{x}{6} = 25 \\ \\ \therefore \: \frac{6x - 4x}{4 \times 6} = 25 \\ \\ \therefore \: \frac{2x}{24} = 25 \\ \\\therefore \: \frac{x}{12} = 25 \\ \\ \implies \: x = 25 \times 12 \\ \implies \: x =300 \: miles \\ \\ rate \: of \: bus = \frac{x}{6} = \frac{300}{6} = 50 \: mph\\ \\ rate \: of \: train = \frac{x}{4} = \frac{300}{4} = 75 \: mph[/tex]

Answer:
[tex]F(x)=\left\{\begin{array}{cl}15(40-x)&\text{if $0<x<40$}\\0&\text{if $40\le x\le65$}\\15(x-65)&\text{if $x>65$}\end{array}\right.[/tex]
Step-by-step explanation:
(a) For x below 40, the number of miles per hour below 40 is (40-x). Then the fine for that speed is 15(40 -x).
For x between limits, the fine is zero.
For x above 65, the number of miles per hour above 65 is (x-65). Then the fine for that speed is 15(x -65).
[tex]F(x)=\left\{\begin{array}{cl}15(40-x)&\text{if $0<x<40$}\\0&\text{if $40\le x\le65$}\\15(x-65)&\text{if $x>65$}\end{array}\right.[/tex]
point w is on line segment VX. Given vx=4x, vw=3x and wx=5 determine the numerical length of vx
Answer:
Numerical length of VX = 20
Step-by-step explanation:
Given that VX is a line segment which has a point W on it.
Kindly refer to the attached diagram for the given points.
We are also given the following dimensions:
[tex]VX=4x\\VW=3x\ and \\WX=5[/tex]
To find:
Numerical length of VX = ?
Solution:
As we can clearly see from the attached diagram:
[tex]VX = VW + WX[/tex]
Putting the given values:
[tex]4x=3x+5[/tex]
Now, let us solve for [tex]x[/tex] and then will put the value of [tex]x[/tex] back to find the numerical value of VX.
[tex]\Rightarrow 4x-3x=5\\\Rightarrow x =5[/tex]
Now,
[tex]VX = 4 \times x = 4\times 5 =\bold{20}[/tex]
Therefore, numerical value of VX is 20.
the day before the day before yesterday is three days after Saturday. what day is it today?
Answer:
Friday
Step-by-step explanation:
We can use logic/equations to solve this problem.
Let's create the equation:
the day before the day before yesterday = saturday + 3 days
We can simplify the right side down.
3 days after Saturday is Tuesday.
So:
the day before the day before yesterday = Tuesday
The day before the day before yesterday is the same as 3 days before today. So:
3 days before today = Tuesday
This means that today is 3 days after Tuesday. 3 days after Tuesday is Friday, so today is a Friday.
Hope this helped!
