Drops of yellow pigment is 8.
A ratio is a comparison of two identical values that makes it simple to compare them. This is how a fraction with a numerator and denominator comparison is expressed. Depending on the ratio formula employed in various parts of mathematical computation, the definitions of the numerator and denominator may change.
For a certain shade of green, y = yellow and b = blue, where y/b = 2/3.
How many yellow drips are needed if there are 12 drops of blue,
y/b = 2/3 = x/12
= 2 × 12 = 3 × x
= 24 = 3x
= 24/3 = x
= x = 8
If you have 12 droplets of blue, you will need 8 drops of yellow.
y/b = 2/3
y = 2/3 × b
Substituting the value b = 12
y = 2/3 × 12
y = 24/3 = 8

Determine whether each series is arithmetic or geometric. Then evaluate the finite series for the specified term number. 2+6+18+ . . . . . . ; n=6
The given series is a geometric series. The sum of its first 6 terms is 728.
To determine whether the series is an arithmetic or geometric one, we need to check how the consecutive terms relate to each other.
If it is an arithmetic series, then:
a(n) = a(n-1) + d
where d is the common difference.
If it is a geometric series, then:
a(n) = a(n-1) . r
where r is the common ratio.
The given series is:
2+6+18+ . . . .
and the number of terms is 6.
In the given series:
a(1) = 2
a(2) = 6
a(3) = 18
Notice that
a(2)/a(1) = 6/2 = 3
a(3)/a(2) = 18/6 = 3
Since the ratio of consecutive terms are constant, then the given series is a geometric series. Furthermore, its ratio, r = 3
Sum formula for the first n term of a geometric series is:
S(n) = a(1) . (rⁿ -1)/(r -1)
Substitute n = 6, a(1) = 2, and r = 3
S(6) = 2 . (3⁶ - 1)/(3 - 1)
S(6) = 2. 364
= 728
We can also evaluate the sum directly. Write all the terms until n = 6.
a(4) = 18 . 3 = 54
a(5) = 54 . 3 = 162
a(6) = 162 . 3 = 486
Hence, the series is:
2+6+18+54+162+486 = 728

A. 54pi inches
B. 216pi inches
C. 6pi inches
D. 24pi inches
E. None of the above
The area of one of the slices is 54π square inches
What is the area of one of the slices?The given parameters are
Diameter = 36 inches
Number of slices = 6
The pie represents take the shape of a circle
And the area (A) of a circle using the diameter (d) is
A= π(d/2)^2
Multiply the above area by 1/6 to get the area of a slice of the pie
So, we have
Area = 1/6 * π(d/2)^2
This means that the area of one of the slices is calculated by
Area = 1/6 * π(d/2)^2
Where
d represents the diameter of the pie i.e. d = 36 inches

You call your parents to explain your issue with having a smashed phone and your parents travel at 0 meters in 2.5 hours. How fast did your parents rush to get here?
After calling the parents, and explaining them the issue of smashed phone, they travelled at a speed of 2.223 m/s = 8.0028 km/hr
As per the question statement, we are given that we call our parents to explain our issue with having a smashed phone and your parents travel at 20000 meters in 2.5 hours. We are supposed to find out that how fast did the parents rush to get here. Basically we have to find their speed of travelling.
Before solving the question, we must be aware that what is speed.
[tex]speed = \frac{distance}{time}[/tex]
and distance and time should be in SI units.
Given distance = 20,000 meters
Given time = 2.5 hours
[tex]1 hour = 60 min\\2.5 hour = 2.5*60\\2.5 hour = 150 min[/tex]
[tex]1 min = 60 sec\\150 min = 150*60 sec\\150 min= 9000 sec[/tex]
Therefore given time = 9000 sec
Therefore speed = [tex]\frac{distance}{time} = \frac{20000}{9000}[/tex]
Speed= 2.223 m/sec
Hence they travelled at a speed of 2.223 meters per second
2.223 m/s = 8.0028 km/hr

landscaping and earned a total of $134. Write a system of equations that could be used to determine the number of hours Aisha worked babysitting last week and the number of hours she worked landscaping last week.
The number of hours Aisha worked babysitting and landscaping last week is 7.9 hours and 9.9 hours respectively.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have been given that Aisha is working two summer jobs, making $7 per hour babysitting and $8 per hour landscaping
Let the number of hours babysitting would be x
And the number of hours landscaping would be y
Last week Aisha worked 2 more hours babysitting than hours landscaping and earned a total of $134.
y = x + 2
7x + 8y = 134
Substitute the value of y = x + 2 in the equation,
7x + 8(x + 2) = 134
7x + 8x + 16 = 134
15x = 134 - 16
15x = 118
x = 118/15
x = 7.9
Substitute the value of x = 7.9 in the equation y = x + 2 ,
y = 7.9 + 2
y = 9.9
Therefore, the number of hours Aisha worked babysitting and landscaping last week is 7.9 hours and 9.9 hours respectively

Answer:
(x,y)=(10,8)
Step-by-step explanation:
Let x be hours worked babysitting and y be hours worked landscaping.
We would have our first equation, 7x+8y=134.
Knowing that she worked 2 more hours babysitting than landscaping, we can determine and replace the x variable as: x=y+2
7(y+2)+8y=134
Use the distributive property to multiply 7 by y+2.
7y+14+8y=134
Combine 7y and 8y to get 15y.
15y+14=134
Subtract 14 from both sides.
15y=134−14
Subtract 14 from 134 to get 120.
15y=120
Divide both sides by 15.
y=120/15
Divide 120 by 15 to get 8.
y=8
and since she worked 2 more hours babysitting, x=10.
Let's replace our values in the original equation:
7x+8y=134
7(10)+8(8)=134.
70+64=134.
Therefore, we can conclude that Aisha worked 10 hours babysitting and 8 hours landscaping last week.

Betsy has a bag with three mint sticks eight jelly treats and nine fruit tart chews if she eats one piece every three minutes what is the probability her first two pieces will be a fruit tart chew and a jelly treat
If Betsy has a bag with three mint sticks, eight jelly treats, and nine fruit tart chews and she eats one piece every three minutes, the probability her first two pieces will be a fruit tart chew and a jelly treat is 18.9%.
The probability of her first two pieces being a fruit tart chew and a jelly treat can be calculated as follows,
First, we divide the expected outcomes by the total possible outcomes.
Total possible outcomes = 3(mint sticks) + 8(jelly treats) + 9(fruit tart chews) = 20
Hence,
Probability for fruit tart chew: 9 ÷ 20
Probability for jelly treat: 8 ÷ 19 (as one possibility is considered to be fruit tart chew)
The probability of her first two pieces to be fruit tart chew and jelly treat can be determined by multiplying the probability for fruit tart chew with the probability for jelly treat,
Probability = (9/20)(8/19)
Probability = 72/380 = 0.189
Converting into percentage,
Probability = 0.189 × 100 = 18.9%
Hence, the probability that her first two pieces will be a fruit tart chew and a jelly treat is equal to 18.9%.

What is completing the square?
Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial .
To solve ax²+bx+c=0 by completing the square:
1. Transform the equation so that the constant term, c , is alone on the right side.
2. If a , the leading coefficient (the coefficient of the x² term), is not equal to 1 , divide both sides by a .
3. Add the square of half the coefficient of the x -term, to both sides of the equation.
4. Factor the left side as the square of a binomial.
5. Take the square root of both sides. (Remember: (x+q)²=r is equivalent to x+q= ±√ r.)
6. Solve for x .
According to the question

The rate of interest is 0.26%
Given,
The amount borrowed by Fred to start a new e-commerce business = $13100.
Time of investment = 13 years.
Interest for the money = $3916.90

P = Principal amount
R = Rate of interest
I = Interest
T = Time period
Here,
P = 13100
I = 3916.90

Write the equation of the line in slope-intercept form.
3y+9=-6x
The equation of the line in slope-intercept form is y = (-2)x + (-3) .
The equation of a line in slope-intercept form can be written as follows,
y = mx + c equation 1
m in the above equation represents slope of the line and c represents the intercept.
The given equation is 3y + 9 = -6x .
To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as
3y + 9 = -6x
3y = -6x - 9
