The quotient of 25 and 5 increased by 3
Answer: 8
Step-by-step explanation: Based on the given conditions, formulate 25/5+3 Reduce the sum or difference: to 8 therefore the answer is 8
Answer:
down below
Step-by-step explanation:
The quotient means the total amount that comes from dividing two things. In this case, the problem is asking for 25 and 5 to be divided. 25 divided by 5 is 5. You can check this by multiplying 5 and 5 to get 25. So, you know it's right. Now, take 5 and add 3 to it. 5 + 3 = 8. So, the answer is 8.

William and Debra Pierce are celebrating their 20th anniversary by having a reception at a local reception hall. They have budgeted $2000 for their reception. If the reception hall charges a $70 cleanup fee plus $30 per person, find the greatest number of people that they may invite and still stay within their budget.
Answer:
The answer is 64 people.
Step-by-step explanation:
If they invite 64 people and all of them show up you multiply that by 30 you get 1,920 add 70 to that and you get 1,990. The reason that 64 is the maximum is because if it were 65 it would go over their budget and if it were below 64 then we wouldn't be getting the greatest number possible.

There are red, yellow, blue and green counters in a bag. The probability of picking red is 0.25. The probability of picking yellow is 0.15. The probability of picking blue is 0.2. Work out the probability of picking green? *
Answer:
The probability of picking a green is 0.4
Step-by-step explanation:
Mathematically, when we talk of the highest possibility an event can have, we have the answer as 1
Hence, when we add up all the probabilities, it is expected that we arrive at a value equal to 1
Thus, the probability of selecting each individual colors add up to 1
since we have the probability of three colors, the probability of the fourth will be the sum of the others subtracted from 1
we have the probability of picking a green as;
1 - 0.25 - 0.15 - 0.2 = 0.4

Christopher has set up a lemonade stand outside his house and sells small cups and large cups of lemonade. Each small cup holds 10 ounces of lemonade and each large cup hold 20 ounces of lemonade. Christopher used 800 ounces of lemonade and sold twice as many small cups as large cups. Graphically solve a system of equations in order to determine the number of small cups sold, x , x, and the number of large cups sold, y y.
Christopher sold 20 cups of large 20-ounce cups of lemonade
outside his house.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, Christopher has set up a lemonade stand outside his house and sells small cups and large cups of lemonade.
Small cups sold is x and the number of large cups sold is y.
Each small cup holds 10 ounces of lemonade and each large cup holds 20 ounces of lemonade and he sold 800 ounces.
Therefore,
10x + 20y = 800...(i)
He also sold twice as many small cups as large cups.
Therefore,
2y = x...(ii)
10(2y) + 20y = 800.
20y + 20y = 800.
40y = 800.
y = 20.
So, He sold 20 cups of large lemonade.

On solving the provided question, we can have that by unitary method the answer will be total salary = 4 * 2340 = $ 9360
What is unitary method ?
The unit technique is an approach to problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. The unit method, to put it simply, is used to extract a single unit value from a supplied multiple. For instance, 40 pens would cost 400 rupees, or the price of one pen. The process for doing this may be standardized. a single country. anything that has an identity element. (mathematics, algebra) (Linear algebra, mathematical analysis, mathematics of matrices or operators) Its adjoint and reciprocal are equivalent.

What type of graph is absolute value?
On [0,∞] the function grows, whereas on [-∞, 0], it shrinks. f has absolute minimum value is 0, and it also has the same relative minimum value (0,0).
What does an absolute value graph look like?On the graph, you are able to see a "open circle" at it when x< 0. (0, 0).
This is due to the fact that, as we've previously demonstrated, the points at y = x approaching (0, 0) as the x-values approach 0.Since x needs strictly be less than zero on only this stretch, the open circle being drawn in its place.When x ≥ 0, a point in (0, 0) is plugged in, thus "plugging" the hole shown by either open circle.Therefore, we get:On [0,∞] the function grows, whereas on [-∞, 0], it shrinks. Function f absolute minimum value is 0, and it also has the same relative minimum value (0,0).F has absolute minimum value is 0, and it also has the same relative minimum value (0, 0). F's highest relative value is zero.There consequently no absolute maximum value of f due to the graph's infinitely high y values.

If you simplify(x^3/x/x)^3, what power rules do you need to simplify it? a. Addition Rule and Power of a Power Rule b. Subtraction rule and Power of a Power. c. Division Rule and Power of a Power Rule d. Power of a Product Rule and Power of a Power Rule e. None of these choices
Answer:
. c. Division Rule and Power of a Power Rule
Step-by-step explanation:
(x^3/x/x)^3
=(x³/x/x)³
First we need to solve the brackets. Anything written in the fraction form a/b/c can be written as a*c/b.
Similarly (x³/x/x)³ can be written as (x*x³/x)³
Solving further the x can be cancelled by x leaving x³ behind.
(x³)³
Now applying the Power of a Power Rule
x³*³= x⁹
First the division rule and then the power rule is applied.

What is the solution for 3x 2y 5?
The solution for 3x 2y 5 is x = 0 and y = -2.5
The solution for 3x 2y 5 can be found by first rewriting the equation in standard form, which is ax + by = c. In this case, the standard form would be 3x + 2y = -5.
Next, we can calculate the value of y in terms of x by using the following formula:
y = (c - ax) / b
Substituting in the values, we get:
y = (-5 - 3x) / 2
Now, we can substitute this expression for y into the original equation to solve for x:
3x + 2((-5 - 3x) / 2) = -5
3x + (-5 - 3x) = -5
6x + -5 = -5
6x = 0
x = 0
Finally, substituting x = 0 into the expression for y, we get:
y = (-5 - 3(0)) / 2
y = (-5 - 0) / 2
y = -5 / 2
y = -2.5
The solution for 3x 2y 5 is x = 0 and y = -2.5
