We can Add 7 black beads to make ratio 3 : 1.
Since we can only change the number of black beads, decide how many black beads you will add based on how many white beads there are.
There are three white beads in the picture.
Total beads we will have (b meaning black)b : 3
Ratio black : white beads 3 : 1
Use the common ratio, which is a number that both sides of the original ratio multiply by to get to the new ratio.
Find common ratio by dividing total by ratio white beads: 3/1 = 3
Multiply ratio black beads by common ratio. 3 X 3 = 9
We need 9 black beads in total.
Check answer
9 : 3
Both sides divisible by 3; reduce ratio
= 3 : 1
Which is Correct ratio
Hence, There will be a total of 9 black beads, but we already have 2 black beads:
(9 total) - (2 original) = (7 to add)
Therefore , we need to add 7 black beads.

The perimeter of the shape is 51.42 cm
Calculate the value of the diameter d.
Take to be 3.142
TU
Answer:
The perimeter of a circle is equal 2 * pi * radius. So, if we let "d" be the diameter of the circle, we can use the following to solve for the radius:
Perimeter = 2 *p * radius = 51.42 cm
we can then use the relationship between the diameter and the radius to solve for the diameter:
d = 2 * radius
substitute the value of the perimeter equation into the diameter equation:
d= 2 * (51.42 cm / 2 * 3.142)
d= 33.49 cm
therefore, the diameter d is 33.49 cm

You are the pilot of an airplane delivering passengers, mail, andfood.- The plane has a total payload capacity (total weight ofpassengers and cargo) of 10,000 pounds.- Your co-pilot weighs 195 pounds.- The food weighs 500 pounds.- The mail weighs 100 pounds.- The total weigh of the 10 passengers onboard is 2000 pounds.- The total weigh of the luggage is 400 pounds.Write and solve an equation to find C, the weight capacity of morefood to carry on the plane that will not exceed the payloadcapacity. Include your weight since you are flying the plane.
The total total payload capacity is 10,000 pounds, which means that the sum of all the weight inside the plane must add up at maximum 10,000. The co-pilot weighs 195 pounds, the food weighs 500 pounds, the mail weighs 100 pounds, the total weigh of the 10 passengers onboard is 2000 pounds, the total weigh of the luggage is 400 pounds, and adding your weight since you're the pilot, that's an extra 175 pounds. Adding all those values together and subtracting from the total payload, will give to us how much we can still add without exceding the weight capacity.
\(C=10,000-(195+500+100+2000+400+175)\)Solving this expression, we have
\(\begin{gathered} C=10,000-(195+500+100+2000+400+175) \\ C=10,000-3,370 \\ C=6,630 \end{gathered}\)The plane can still carry an extra weight of 6,630 pounds.

D. If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.
Step-by-step explanation:
The zeroes of the quadratic function is x = 2.05 and x = 14.61
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
y = -6x² + 100x + 180 be equation (1)
where x = selling price of each soccer ball
y = daily profit from soccer balls
On factorizing the equation , we get
when y = 0
6x² - 100x - 180 = 0
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
x = [ 100 ± √ ( 100 )² - 4 ( 6 ) ( 180 ) ] / 12
x = [ 100 ± √ ( 10000 ) - 4320 ) ] / 12
x = [ 25 ± √355 ] / 3
So , the two values of x are x = 2.05 and x = 14.61
Hence , the zeroes of the function are 2.05 and x = 14.61

How many solutions does the system of equations below have? y=-3/4x+1/6
The solution is the point (0, 1/6) y = 1/6
Given the equation y = (-3/4)x + 1/6, which represents a linear equation, there is no "system" of equations involved since there is only one equation.
In this case, the equation is in slope-intercept form (y = mx + b),
where m represents the slope (-3/4) and b represents the y-intercept (1/6).
The slope-intercept form allows us to determine various properties of the equation.
Since there is only one equation, the solution to this equation is a single point on the Cartesian plane.
Each pair of x and y values that satisfy the equation represents a solution.
For example, if we choose x = 0, we can substitute it into the equation to find the corresponding y value:
y = (-3/4)(0) + 1/6
y = 1/6
Therefore, the solution is the point (0, 1/6).
In summary, the given equation has a unique solution, represented by a single point on the Cartesian plane.
Any value of x plugged into the equation will yield a corresponding y value, resulting in a unique point that satisfies the equation.

2x-15< -0.8 or 2x-15> 0.8 solve and write in interval notation
Answer:
Step-by-step explanation:
To solve the inequalities 2x - 15 < -0.8 and 2x - 15 > 0.8, we will solve them separately and then combine the solutions.
First, let's solve the inequality 2x - 15 < -0.8:
2x - 15 < -0.8
Add 15 to both sides:
2x < 14.2
Divide both sides by 2 (since the coefficient of x is 2 and it is positive, we don't need to flip the inequality symbol):
x < 7.1
Now, let's solve the inequality 2x - 15 > 0.8:
2x - 15 > 0.8
Add 15 to both sides:
2x > 15.8
Divide both sides by 2:
x > 7.9
So, the solutions to the inequalities are:
x < 7.1 and x > 7.9
To write these solutions in interval notation, we can express them as separate intervals and then combine them using the union symbol (∪):
Interval 1: (-∞, 7.1)
Interval 2: (7.9, +∞)
Combining these intervals, the solution in interval notation is:
(-∞, 7.1) ∪ (7.9, +∞)
What is the area of the square that measures 3.1 m on each side
The area of the square with a side length of 3.1 meters is 9.61 square meters.
To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.
Area of a square = side length × side length
Substituting the given side length into the formula:
Area = 3.1 m × 3.1 m
To perform the calculation:
Area = 9.61 m²
It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.
Remember, to find the area of any square, you simply need to multiply the length of one side by itself.

-The smallest slope on the curve is
-The curve has the smallest slope at the point
c) Find equations for the tangent lines to the curve at the points where the slope of the curve is 8.
Answer:
f(x) = x³ - 4x + 6
f'(x) = 3x² - 4
a) f'(2) = 3(2²) - 4 = 12 - 4 = 8
6 = 8(2) + b
6 = 16 + b
b = -10
y = 8x - 10
b) 3x² - 4 = 0
3x² = 4, so x = ±2/√3 = ±(2/3)√3
= ±1.1547
f(-(2/3)√3) = 9.0792
f((2/3)√3) = 2.9208
c) 3x² - 4 = 8
3x² = 12
x² = 4, so x = ±2
f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6
6 = -2(8) + b
6 = -16 + b
b = 22
y = 8x + 22
f(2) = 6
y = 8x - 10
The equation perpendicular to the tangent is y = -1/8x + 25/4
-The smallest slope on the curve is 2.92
The curve has the smallest slope at the point (1.15, 2.92)
The equations at tangent points are y = 8x + 16 and y = 8x - 16
Finding the equation perpendicular to the tangentFrom the question, we have the following parameters that can be used in our computation:
y = x³ - 4x + 6
Differentiate
So, we have
f'(x) = 3x² - 4
The point is (2, 6)
So, we have
f'(2) = 3(2)² - 4
f'(2) = 8
The slope of the perpendicular line is
Slope = -1/8
So, we have
y = -1/8(x - 2) + 6
y = -1/8x + 25/4
The smallest slope on the curveWe have
f'(x) = 3x² - 4
Set to 0
3x² - 4 = 0
Solve for x
x = √[4/3]
x = 1.15
So, we have
Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6
Smallest slope = 2.92
So, the smallest slope is 2.92 at (1.15, 2.92)
The equation of the tangent lineHere, we set f'(x) to 8
3x² - 4 = 8
Solve for x
x = ±2
Calculate y at x = ±2
y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)

P(5): Since there is only one face with a value of 5 on the die, the probability of rolling a 5 is 1/6.P(1 or 2): There are two faces with the values 1 and 2 respectively. Since these are mutually exclusive events (you can only roll one of them at a time), the probability of rolling a 1 or a 2 is 2/6, which simplifies to 1/3.P(odd number): Out of the six faces, three are odd numbers (1, 3, and 5). So, the probability of rolling an odd number is 3/6, which simplifies to 1/2.P(not 6): Since there is only one face with a value of 6, the probability of not rolling a 6 is 5/6.P(even number): Out of the six faces, three are even numbers (2, 4, and 6). So, the probability of rolling an even number is 3/6, which simplifies to 1/2.P(1, 2, 3, or 4): There are four faces with the values 1, 2, 3, and 4.
