Create a ratio table for making lemonade with a lemon juice to water of ratio of 1:3 show how much lemon juice would be needed if u use 36 cups of water to make lemonade
There is 1 serving of lemon juice to 3 cups water. Hence why it's 1:3 ratio.
Since it's 1:3, then 2 servings to 6 cups of water, so on and so forth.
Multiply your lemon juice servings by 3 to find out how many cups of water for the table.
To find how much lemon juice for 36 cups of water, just divide 36 by 3 to get 12. 12 servings of lemon juice is just right for your 36 cups of water.
Answer: There is 12 servings of lemon juice needed for 36 cups of water.
Step-by-step explanation:
Since we have given that
Number of cups of water to make lemonade = 36
Ratio of lemon juice to water = 1 : 3
So, number of lemon juice cups be x
number of cups of water be 3x.
According to question, it becomes,
[tex]3x=36\\\\x=\dfrac{36}{3}\\\\x=12[/tex]
Hence, there is 12 servings of lemon juice needed for 36 cups of water.
what is the value of "m" equal?
First, let's convert the radical terms to exponents. Remember the following:
[tex]\sqrt[n]{x^m} = x^\frac{m}{n}[/tex]
[tex]\sqrt{x^5} = x^{\frac{5}{2}}[/tex]
[tex]\sqrt[4]{x^9} = x^{\frac{9}{4}}[/tex]
[tex]\sqrt[6]{x^5} = x^{\frac{5}{6}}[/tex]
After substituting in the values we just found, our expression looks like:
[tex]\dfrac{(x^{\frac{5}{2}})(x^{\frac{9}{4}})}{x^{\frac{5}{6}}}[/tex]
Now, remember that we can add the exponents of terms that have the same base and are being multiplied by each other. Also, remember that we can subtract the exponents of terms with the same base that are being divided by each other. This is represented as:
[tex]x^a \cdot x^b = x^{(a + b)}[/tex]
[tex]\dfrac{x^c}{x^d} = x^{(c - d)}[/tex]
Thus, we can simplify our expression even more:
[tex]\dfrac{(x^{\frac{5}{2}})(x^{\frac{9}{4}})}{x^{\frac{5}{6}}}[/tex]
[tex]\dfrac{x^{\frac{19}{4}}}{x^{\frac{5}{6}}}[/tex]
[tex]x^{\frac{47}{12}}[/tex]
Our answer is [tex]\boxed{m = \dfrac{47}{12}}[/tex].

If a die is rolled one time find these probabilities
-of getting less than 7
-Getting a number greater than or equal to 3
In probability, the outcomes of rolling a die are considered. The probability of getting a number less than 7 is 1 or 100% and the probability of rolling a number greater than or equal to 3 is 2/3 or approximately 66.67%
Explanation:This question falls under the topic of probability in Mathematics. In the case of a single die, there are 6 possible outcomes because a die has 6 faces.
For the probability of getting a number less than 7, all outcomes (1,2,3,4,5,6) are less than 7. Thus, the probability is 6 out of 6 or 1.
For the probability of getting a number that's greater than or equal to 3, the favorable outcomes are 3,4,5,6. So, there are 4 such outcomes. The probability, in this case, is 4 out of 6, which simplifies to 2/3.

A boy is X years old. His sister is twice as old he is. The sum of their age is 27, How old is the boy?
The boy is 9
9x2=18
18+9=27
In this explanation, we'll determine the age of the boy using algebraic equations based on the given information. Let's represent the boy's age as X and his sister's age as 2X.
Let's set up the equations based on the information provided:
1. The boy's age: X years
2. His sister's age: 2X years (twice as old as the boy)
3. The sum of their ages: 27 years
Using these three pieces of information, we can create an equation to find the value of X (the boy's age).
1. The first equation represents the sum of their ages:
X + 2X = 27
2. Simplify the equation by combining like terms:
3X = 27
3. Now, isolate X by dividing both sides of the equation by 3:
X = 27 / 3
4. Calculate X:
X = 9
So, the boy is 9 years old.
Let's represent the boy's age as X and his sister's age as 2X. The sum of their ages is given as 27 years.
1. We can express the sum of their ages in an equation:
X + 2X = 27
2. Combine the like terms on the left side of the equation:
3X = 27
3. To find the value of X, isolate X on one side of the equation. We do this by dividing both sides of the equation by 3:
X = 27 / 3
4. Simplify the expression:
X = 9
Thus, the boy is 9 years old, and his sister is twice as old, which makes her 18 years old (2 * 9 = 18).
The sum of their ages, 9 + 18, indeed equals 27.

find the missing part to make the sentence true 5+4= +3
a manufacturer keeps track of her monthly costs by using a cost function this assigns a total cost for a given number of manufactured items X the function is C(x)=5,000 + 1.3x
what is the reasonable domain of this function what is the cost of 2,000 items that the cost must be kept below 10,000 this month what is the greatest number of items she can manufacturer need these answers ASAP please help
Answer:
a)Domain is all positive integers.
b)C(2000)=$7600
c) For C(x)<10000, less than 3846 items should be manufactured.
Step-by-step explanation:
Given that cost function is C(x)=5000+1.3x, where x is the number of manufactured items.
a) The domain of C(x) means the range of values x can take. Since x is the number of manufactured items, it cannot be negative and fraction.
Hence domain is all positive integers.
b)To find the cost of 2000 items, we should plugin x=2000 in C(x).
That is cost of 2000 items, C(2000)=5000+1.3(2000)=5000+2600=$7600
c) We are asked to find the number of items such that cost is kept below 10,000 that is C(x)<10000
5000+1.3x<10000
Subtract 5000 from both sides
1.3x<5000
Divide with 1.3 on both sides
[tex]x<\frac{5000}{1.3}[/tex]
x<3846.2
Hence number of items must be less than 3846 for C(x)<10000
Final answer:
The reasonable domain of the cost function is x >= 0. The cost of 2,000 items that must be kept below $10,000 is $7,600. The greatest number of items that can be manufactured with a cost below $10,000 is 3,846 (rounded down).
Explanation:
The reasonable domain of the cost function is x >= 0 since the number of items manufactured cannot be negative. In other words, the function is valid for all non-negative values of x.
To find the cost of 2,000 items that must be kept below $10,000, we substitute x = 2,000 into the cost function:
C(2,000) = 5,000 + 1.3 × 2,000
Simplifying this equation, we get:
C(2,000) = 5,000 + 2,600 = $7,600
To determine the greatest number of items that can be manufactured with a cost below $10,000, we need to solve the inequality:
5,000 + 1.3x < 10,000
Simplifying this inequality, we have:
1.3x < 5,000
Dividing both sides of the inequality by 1.3, we obtain:
x < 3,846.15
The greatest number of items that can be manufactured with a cost below $10,000 is 3,846 (rounded down).

Evaluate using distributive property
16 x ( -3/8)+16 x 1/4
Final answer:
The expression 16 x (-3/8) + 16 x 1/4 is evaluated using the distributive property to get -6 + 4, which equals -2.
Explanation:
To evaluate the expression 16 x ( -3/8) + 16 x 1/4 using the distributive property, we will distribute the 16 into the terms inside the parentheses.
Here is the step-by-step process:
Multiply 16 by (-3/8): 16 × (-3/8) = -6.
Multiply 16 by 1/4: 16 × 1/4 = 4.
Add these two results together: -6 + 4 = -2.
Therefore, the evaluation of the expression 16 x ( -3/8) + 16 x 1/4 is -2.
Polygon F has an area of 36 square units. Aimar drew a scaled version of Polygon F and labeled it Polygon G. Polygon G has an area of 4 square units
Area is a squared number. We know that from the label we use when we solve problems involving area. Perimeter is a single unit label. This single unit label can also be used to find scale factor, since single unit labels are one-to-one. If the area of polygon F is 36, that means that the single unit measure was a number that was squared to get to the area. Same goes for polygon G. That means that in order to find the single unit measure of each of those we have to take the square root of the area. The square root of 36 is 6, and the square root of 4 is 2. 6:2 is the scale factor, but that can be reduced to 3:1, larger to smaller.

Mrs. whimsey's class is having a pizza party . If there are 16 student and 4 pizzas cut into 8 slices , what answer choice represents the function of one pizza each student receives
Final answer:
Each student will receive 2 slices of pizza, as there are a total of 32 slices from 4 pizzas divided among 16 students.
Explanation:
To determine the number of pizza slices each student receives, we need to calculate the total number of slices available and then divide this by the number of students. Given that there are 4 pizzas and each pizza is cut into 8 slices, we have:
Multiply the number of pizzas by the number of slices per pizza: 4 pizzas × 8 slices/pizza = 32 slices.
Divide the total number of slices by the number of students: 32 slices ÷ 16 students = 2 slices/student.
Therefore, the function that represents the number of pizza slices each student receives is 2 slices per student.

Round your answer to the nearest whole number.
A manufacturing company has the following fixed monthly costs and unit variable costs:
Rent = $2,200
Utilities = $375
Variable costs for materials and assembly = $13.25/unit
Monthly labor = $750
Given is the product is sold at $24.99 per unit
Let the number of units sold be x
Adding total cost = [tex]2200+375+750=3325[/tex]
Equation becomes:
[tex]3325+13.25x=24.99x[/tex]

... -5(y-9) = -2(x+9) . . . . add the opposite of the x-term
... y - 9 = 2/5(x +9) . . . . this is the point-slope form you want
_____
To put the equation in general form, multiply by the common denominator of any fractions, and subtract the stuff on the right side of the equal sign. Factor out any common factors of the integer coefficients and constant, and multiply by -1 if the leading coefficient is negative.*
Here, we multiply by 5 (and eliminate parentheses) to get
... 5y -45 = 2x +18
... -2x +5y -63 = 0 . . . . right side subtracted
... 2x -5y +63 = 0 . . . . . leading coefficient made positive. This is your general form.
___
* Actually, I can find no requirement that General Form have a positive leading coefficient. Nor is there a requirement that the coefficients be mutually prime. However, these are requirements for the very similar Standard Form, which has the constant on the right side of the equal sign, instead of the left. Since leading minus signs tend to get lost, IMO, it is a good idea to make the leading coefficient positive, even if it is not a requirement.
