How many Great Balls could you purchase for $3,000 if each one costs $600?
Answers
Answer: 5 for 600 each
There are 50 great balls.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Cost of 1 great ball = $600
Total amount = $3000
So, number of Great balls
= 3000 / 600
= 50
hence, there are 50 great balls.

if alpha and beta are zeroes of x2-3x+q. what is the value of q, if 2 alpha+3 beta=15
Answers
The value of q is -27.
Recall Vieta's Formulas, which state that for a quadratic equation \(ax^2\) + bx + c = 0 with zeroes alpha and beta, the sum of the zeroes is equal to -b/a, and the product of the zeroes is equal to c/a.
In our equation \(x^2\) - 3x + q, the sum of the zeroes alpha and beta is -(-3)/1 = 3.
We are given that 2 alpha + 3 beta = 15. Substitute alpha = (15 - 3 beta)/2 into the equation.
Replace the value of alpha in the sum of zeroes equation: (15 - 3 beta)/2 + beta = 3.
Simplify the equation by multiplying both sides by 2: 15 - 3 beta + 2 beta = 6.
Combine like terms: 15 - beta = 6.
Subtract 15 from both sides: -beta = -9.
Multiply both sides by -1 to solve for beta: beta = 9.
Substitute the value of beta into the sum of zeroes equation: alpha = (15 - 3 * 9)/2 = -3.
Since we have the values of alpha and beta, we can find q using the product of the zeroes formula: q = alpha * beta = -3 * 9 = -27.

alice has 24 apples. in how many ways can she share them with becky and chris so that each of the people has at least 2 apples?
Answers
Assuming Alice has 2 apples, there are 19 ways to split the rest of the apples with Becky and Chris.
The total number of ways to split 24 apples between the three friends is equal to 19 + 18 + 17 + 16 + 15 + ...……+ 2 + 1 = 20 x ( 19 / 2 ) = 190
Alice can share them with Becky and Chris in a variety of ways, as long as each person has at least 2 apples. For example, Alice could give Becky 8 apples and Chris 16 apples, or she could give Becky 10 apples and Chris 14 apples. As long as each person has at least 2 apples, there are many ways for Alice to share her apples.To split the apples, we employ the Ball-and-urn method, also referred to as "Sticks and Stones" or "Stars and Bars."
Hence there are 19 different ways she can share them with becky and chris so that each of the people has at least 2 apples.

The precision of the investigation and the recovery of the products can both be impacted by experimental mistakes. The stock solution could be diluted by the student using an inaccurate volume measurement, leading to a higher concentration over desired. For instance, the student might pipette their stock solution before dilution and accidentally add extra volume.

That being said we can use this equation to solve for x
108 = 3x + 5 + 2x + 3
step 1 combine like terms
3x + 2x = 5x
3 + 5 = 8
now we have 108 = 5x + 8
step 2 subtract 8 from each side
108 - 8 = 100
8 - 8 cancels out
now we have 100 = 5x
step 3 divide each side by 5
100/5=20
5x/5=x
we're left with x = 20
Now we want to find the value of angle B
Knowing the value of x all we have to do is plug in 20 into x for (2x+3)
2(20)+3=angle b
2*20=40
40+3=43
so we can conclude that angle b = 43

Hilaria borrowed $8,000 from her grandfather to pay for college. Four years later, she paid him back the $8,000, plus $1,600 interest. What was the rate of simple interest (as a percent)?
Answers
The rate of simple interest is 0.05, which is equivalent to 5% when expressed as a percentage.
To calculate the rate of simple interest, we can use the formula:
Interest = Principal * Rate * Time
Given that Hilaria borrowed $8,000 and paid back $1,600 in interest after four years, we can set up the equation:
$1,600 = $8,000 * Rate * 4
Divide both sides of the equation by $8,000 * 4
$1,600 / ($8,000 * 4) = Rate
Simplifying the equation: 0.05 = Rate

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.

Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A.
Part C: If the rate at which the candle burned was 0.4 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values.
Will mark Brainlist!!!
Answers
Answer: PART A.
y= remaining height of candle
x= rate the candle burns down in inches per hour
8= original height of candle
the function would be y=8- 0.5x because the candle starts at a height of 8 feet and loses half an inch per hour.
You can use this function to create ordered pairs by putting in number at x which indicates the time:
x=1
y=8- (.5×1)= 7.5
(1, 7.5)
you can then do this for other numbers and get:
(2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)
PART B.
This equation is a function because all of the x-values had different y-values as seen in the coordinates (1, 7.5) (2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)
PART C.
If the rate was 0.4 inches an hour, it would still be a function because the rate is the only thing that changed making the new function y= 8- 0.4x.This equation would make coordinates of (0,8) (1, 7.6) (2, 7.2) (3, 6.8) and so on with each x value creating a different y value.

The graph that represents z and -2z is as shown below.
What is complex number?"The number of the form a + ib where a, b are real numbers and \(i=\sqrt{-1}\)"
What is real part of a complex number?"For a complex number x + iy, 'x' represents the real part."
What is imaginary part of a complex number?"For a complex number x + iy, 'iy' represents the imaginary part of complex number."
For given question,
We have been given a complex number z = -2 + 2i
The real part of the complex number is -2 and imaginary part is 2i
The coordinates would be (-2, 2)
This number lies in the second quadrant.
Now, consider the complex number -2z
⇒ -2z = -2(-2 + 2i)
⇒ -2z = 4 - 4i
The real part of complex number -2z is 4 and the imaginary part is -4i.
The coordinates of the complex number 4 - 4i would be (4, -4)
Therefore, the graph that represents z and -2z is as shown below.

a man left 1/2 of his money to his first son 3/8 to his second son, the rest 80,000 to his third son.how much did he he leave to his second son
Answers
As per the given conditions in the question, the amount of money that the second son was left with by the man is 2,40,000.
How do you add two fractions with different denominators?To add two fractions with different denominators, you must first find a common denominator. A common denominator is a number that is divisible by both denominators of the fractions. Once you have a common denominator, you can add the numerators of the fractions together and place the sum over the common denominator. Then simplify the fraction if possible.
What is the reciprocal of a fraction?The reciprocal of a fraction is another fraction whose numerator and denominator are flipped. For example, the reciprocal of the fraction 2/3 is 3/2. The product of a fraction and its reciprocal is always equal to 1. To find the reciprocal of a fraction, simply swap the numerator and denominator.
Considering the conditions given in the question,let us suppose that the third son was left with x part of the money,
so we can use the equation,
part of money left for fist son + part of money left for second son + part of money left for third son = total part of money
or, 1/2 + 3/8 + x = 1
therefore, x = 1/8
Also we know that the third son was left 80,000 ,
so 1/8 of total money = 80,000
therefore, total money = 80000 * 8 =6,40,000
Now the amount left for the second son is , 3/8 of total money
which is equal to , 3/8 of 6,40,000 = 2,40,000
