Answer:
6%
Step-by-step explanation:
Since the volume of the cylinder V = πr²h where r = radius of cylinder and h = height of cylinder and h = 2r, we have that r = h/2.
Substituting r into v, we have
V = πr²h
V = π(h/2)²h
V = πh³/4
Now let ΔV be the error in the volume and Δh be the error in the height.
Since h is raised to the power of 3,
ΔV/V = 3Δh/h
multiplying both sides by 100, we have
ΔV/V × 100 = 3Δh/h × 100
So, we have
ΔV/V × 100 = 3 × Δh/h × 100
since Δh/h × 100 = percentage error in height = 2%, and ΔV/V × 100 = percentage error in volume,
ΔV/V × 100 = 3 × 2% = 6%
So, the percentage error in volume is 6 %
A radio station gave away 192 tickets to a concert. They gave away 5 times as many tickets to listeners as they gave to employees. How many tickets did they give away to employees?
Answer:
Tickets to workers= 32
Step-by-step explanation:
Giving the following information:
Total tickets= 192
They gave away 5 times as many tickets to listeners as they gave to employees.
We will use the rule of 3:
6/6=192
5/6= ? = 192*(5/6) = 160
They gave 160 tickets to listeners.
Tickets to workers= 192 - 160= 32
Prove:
32*5= 160

Which system of equations has no solution?
5 x + 5 y = 10 and 2 x + 2 y = 4
3 x minus 6 y = 4 and negative 4 x + 8 y = 7
6 x + 2 y = 6 and 7 x + 3 y = 9
3 x minus 4 y = 16 and 2 x + 3 y = 5
The equation which has no solutions is 5 x + 5 y = 10 and 2 x + 2 y = 4
What is equation?
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
As,
5 x + 5 y = 10 and 2 x + 2 y = 4
a1= 5, b1= 5, c1 = -10
a2= 2, b2= 2, c2 = -4
Now, a1/ a2 = 5/2
b1/ b2= 5/2
c1/ c2= -10/-4 = 5/2
Hence, a1/a2= b1/b2= c1/c2
So, the pair of equation has no solution.

Johathan purchases 10 traveler's checks in denominations of $20, $50, and $100, totaling $370.He has twice as many $20 checks as $50 checks. How many of each denomination of traveler's checks does he have?
Answer:
Six 20$ bills, Three 50$ bills, One $100 bill
Step-by-step explanation:
6x20=120
3x50=150
1x100=100
120+150+100=370
and there are twice as many 20$ checks than 50$ checks
find the value of x and y. if (x+y,1) =(2,2x-y)
Answer:
x=1/3. y=3/2
Step-by-step explanation:
x+y=2. =>equation 1
2x-y = 1. => equation 2
equation 1 + equation 2,
x+y+(2x-y) = 2-1
x+y+2x-y = 1
3x = 1
x=1/3
plug in value of x in equation 1,
1/2 + y = 2
y= 2 - 1/2
y = 3/2

moderate negative association
Answer:
perfect positive association.
Step-by-step explanation:
A perfect positive association means that a relationship appears to exist between two variables, and that relationship is positive 100% of the time. In statistics, a perfect positive association is represented by the value +1.00, while a 0.00 indicates no association

the perimeter of the given equilateral triangle is 42 cm find s if it's side length is (3s+2) cm
Answer:
14cm
Step-by-step explanation:
Given parameters:
perimeter of the triangle = 42cm
length of side = (3s + 2)cm
Unknown:
Find the length of each side = ?
Solution:
The perimeter of a body is the sum of all its sides.
In this problem, we have been given an equilateral triangle. For such a triangle, all the sides are equal. So the perimeter is the sum of all the three sides;
(3s + 2) + (3s + 2) + (3s + 2) = 42
9s + 6 = 42
9s = 42 - 6
9s = 36
s = 4;
The length of its sides = 3s + 2
= 3(4) + 2
= 12 + 2
= 14cm
Oliver has of a gallon of water. He pours all of the water into 6 containers. If he pours the same amount of water into each container, how many gallons of water does Oliver pour into each container?
Answer:
I believe it is 1/3 of a gallon
Step-by-step explanation:
because he pours it into 6 containers (which make each container hold 1/6 of a gallon)
then he pours the same amount again which will make it 2/6 of a gallon and 2/6 simplified is 1/3

Determine the average rate of change over left curly bracket negative 4 less or equal than x less or equal than 4 bold right curly bracket. Do NOT simplify.
Answer:
{-4≤ x≤ 4}
The average rate of change would be 1 for f(x) = x.
Step-by-step explanation:
Suppose we have a range a≤x≤b, then the average rate of change can be calculated by =f(b) - f(a)/b-a
The given range lies from -4 to 4 as {-4≤ x≤ 4}
The range of this is from -4 to 4.It includes all the numbers ranging from -4 to 4.
The average rate of change of the function is calculated by
= f(4) - f(-4)/4-(-4)
Suppose f(x)= x then f(4)= 4 and f(-4)= -4
Then
4- (-4)/ 4- (-4)
= 8/8= 1
So the average rate of change would be 1.
