Francisco uses 12 ounces of milk for every 18 ounces of fruit in his smoothie recipe, Nia uses 8 ounces of milk for every 12 ounces of fruit in her smoothie recipe. Who would use more milk if they each use 6 ounces of fruit?

Answers

Answer: there both equal

Step-by-step explanation: first we have to find the unit rate of both. Francisco unit rate for his recipe is 12/18=6/9=2/3 so the unit rate is 2/3

Nia uses 8/12=4/6=2/3 so the both will have the same if they use 6 ounces

Final answer:

Both Francisco and Nia use a proportional amount of milk in their smoothies; thus, they would both use 4 ounces of milk for 6 ounces of fruit.

Explanation:

To determine who would use more milk if they each use 6 ounces of fruit, we need to compare Francisco's and Nia's milk-to-fruit ratios. Francisco uses 12 ounces of milk for every 18 ounces of fruit, and Nia uses 8 ounces of milk for every 12 ounces of fruit. To find how much milk they would use for 6 ounces of fruit, we can set up a proportion for each and solve for the amount of milk.

For Francisco:
12 ounces of milk / 18 ounces of fruit = x ounces of milk / 6 ounces of fruit.
Using cross-multiplication, we get:
18x = 12 × 6.
Dividing both sides by 18 gives us:
x = (12 × 6) / 18 = 4 ounces of milk.

For Nia:
8 ounces of milk / 12 ounces of fruit = y ounces of milk / 6 ounces of fruit.
Using cross-multiplication, we get:
12y = 8 × 6.
Dividing both sides by 12 gives us:
y = (8 × 6) / 12 = 4 ounces of milk.

Therefore, both Francisco and Nia would use 4 ounces of milk for 6 ounces of fruit in their smoothie recipes.

The distance around the pool is 43.96 m.

Solution:

The distance across the circle is diameter.

The distance around the circle is circumference.

The value of π = 3.14

Diameter of the circle = 14 m

Circumference of the circle = πd

                                              = 3.14 × 14 m

Circumference of the circle = 43.96 m

The distance around the pool is 43.96 m.

Step-by-step explanation:

Step 1:  Distribute

To distribute means to break the parenthesis apart.  To make two different combinations.

3(13 + 5)

(3 * 13) + (3 * 5)

Step 2:  Multiply it out

54

Answer:  54 or as an expression (3 * 13) + (3 * 5)

Answer: 39 + 15

Step-by-step explanation: 3(13 + 5) can be simplified by distributing the 3 through both terms that are inside the parentheses.

So we have 3(13) + 3(5) which simplifies to 39 + 15 or 54.

So 3(13) + 3(5) is an equivalent.

30% of number A is 10 more than 20% of number B. 30% of number B is 35 more than 20% of number A. Find the numbers A and B.


PLEASE PLEASE DUE TODAY!!!

Answers

Final answer:

To solve for A and B, we translated the word problem into two algebraic equations and then solved the system of equations step-by-step to find that A equals 200 and B equals 250.

Explanation:

We are given two equations based on the relationship between 30% of number A and 20% of number B, and vice versa. Let's translate the words into algebraic expressions where A and B represent the numbers we need to find:

0.30A = 0.20B + 10 (Equation 1)

0.30B = 0.20A + 35 (Equation 2)

Now let's solve this system of equations step-by-step:

Multiply both sides of Equation 1 by 10 to clear out decimals: 3A = 2B + 100.

Multiply both sides of Equation 2 by 10 as well: 3B = 2A + 350.

Rearrange Equation 1 to get A on its own: A = (2B + 100) / 3.

Substitute the expression for A from step 3 into Equation 2: 3B = 2((2B + 100) / 3) + 350.

Multiply through by 3 to clear the fraction: 9B = 4B + 200 + 1050.

Simplify to find B: 5B = 1250, so B = 250.

Substitute B back into the equation from step 3 to find A: A = (2(250) + 100) / 3, so A = 200.

Therefore, the numbers we are looking for are A = 200 and B = 250.

Solve The Expression :

Step-by-step explanation:

Step 1:  To combine like terms means to add the same variable numbers together.

-6x + 5 - 4x < 45

-10x + 5 < 45

Step 2:  Subtract 5 from both sides

-10x + 5 - 5 < 45 - 5

-10x < 40

Step 3:  Divide both sides by -10

-10x / -10 < 40 / -10

Since you divided by a negative, you need to reverse/flip the sign.

x > -4

Answer:  x > -4

Steps to solve:

-6x + 5 – 4x < 45

~Combine Like Terms

(-6x - 4x) + 5 < 45

~Simplify

-10x + 5 < 45

~Subtract 5 to both sides

-10x + 5 - 5 < 45 - 5

~Simplify

-10x < 40

~Divide -10 to both sides and switch the symbol since we're dividing a negative number

-10x/-10 > 40 / -10

two friends bought a $14 pizza. Each person bought their own drink. The total cost of the food can be represented by the expression $2x + $14. What expression represents the cost of food for one person

Answers

We can just divide 2x+14 by 2 to get the cost of one person, as the equation represents the total costs of two people.

So the equation is x+7, but it may be x+14 because you can’t split the pizza.

I hope this helps!

The expression representing the cost of food for one person is $x + $7.

For the expression that represents the cost of food for one person if two friends bought a $14 pizza, and each person bought their own drink at $2x (where x is the number of drinks).

To find the cost for one person, we start with the total cost expression $2x + $14. Since there are two friends, we divide this total cost by 2. The expression for the cost of food for one person is $x + $7. This represents the individual cost of one person's drink at $2x, divided by 2, plus half of the pizza cost, which is $14 divided by 2, resulting in $7.

Hank wins
Marvin wins

Answers

Answer: Aly , Marvin, Hank

Step-by-step explanation:

Aly has the lowest with 20, Marvin has 30, and hank has 50. it says least to mostly likely to win

Final answer:

The question pertains to probabilities. It has been determined that the most probable event is either Hank winning or Marvin winning, and it's least likely for Aly to win.

Explanation:

The question is regarding the probability of three individuals, Marvin Martian, Aly Alien, and Hank Human, finding a hidden spaceship first. We know the probabilities of Marvin and Aly finding it first but the probability of Hank finding it is not given.

However, from the properties of probability, we know that the sum of the probabilities for all possible outcomes is 1. Therefore, if we add the probabilities of Marvin and Aly finding the spaceship first, we get 0.30(30%) + 0.2(20%) = 0.5(50%). We then subtract this from 1 to get Hank's probability, which is, therefore, 1 - 0.5 = 0.5(50%).

So, in order from least to most likely: Aly wins (0.2 or 20%), then Hank and Marvin are equally likely to win (0.5 or 50% each).

If (6,39) and (-5,-49) are two anchor pint find the equation of the line

Answers

Answer:

[tex]y =8x+9[/tex]

Step-by-step explanation:

The points are (6,39) and (-5,-49)

We need to find the equation of this line.

The slope is given by:

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

[tex]m = \frac{ - 49 - 39}{ - 5 - 6} [/tex]

[tex]m = \frac{ - 88}{ - 11} [/tex]

[tex]m = 8[/tex]

We use the formula:

[tex]y-y_1=m(x-x_1)[/tex]

We substitute the point (6,39) and m=8 to get:

[tex]y - 39 = 8(x - 6)[/tex]

We expand to obtain:

[tex]y - 39=8x-48[/tex]

[tex]y =8x-48 + 39[/tex]

[tex]y =8x + 9[/tex]

To find the equation of the line passing through two points, we can use the point-slope form of a linear equation:

[tex]\[y - y_1 = m(x - x_1)\][/tex]

Where:

- [tex]\( (x_1, y_1) \)[/tex] is one point on the line.

- [tex]\( m \)[/tex] is the slope of the line.

First, let's find the slope (\(m\)) using the two given points:

[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]

Given points:

[tex]\( (x_1, y_1) = (6, 39) \)\( (x_2, y_2) = (-5, -49) \)\[ m = \frac{-49 - 39}{-5 - 6} \]\[ m = \frac{-88}{-11} \]\[ m = 8 \][/tex]

Now, we have the slope (\(m\)). We can choose either of the two given points and plug them into the point-slope form. Let's use \( (6, 39) \):

[tex]\[ y - 39 = 8(x - 6) \][/tex]

Now, we can simplify this equation to get it into slope-intercept form (\(y = mx + b\)):

[tex]\[ y - 39 = 8x - 48 \]\[ y = 8x - 48 + 39 \]\[ y = 8x - 9 \][/tex]

So, the equation of the line passing through the points (6, 39) and (-5, -49) is [tex]\( y = 8x - 9 \).[/tex]

3. Given the function f(x)=x^2+3x-2
What is the average rate of change for the function from 2 to 6? Show your work.

Answers

Question 1

The given system of equations is:

[tex]y = {x}^{2} + 5x + 6 \\ y = 3x + 6[/tex]

Equate the two equations:

[tex] {x}^{2} + 5x + 6 = 3x + 6[/tex]

Rewrite in standard form:

[tex] {x}^{2} + 5x - 3x + 6 - 6 = 0[/tex]

[tex] {x}^{2} + 2x = 0[/tex]

[tex]x(x + 2) = 0[/tex]

[tex]x = 0 \: or \: x = - 2[/tex]

When we put x=0, in y=3x +6, we get:

[tex]y = 3(0) + 6 = 6[/tex]

One solution is (0,6)

When we put x=-2, into y=3x+6, we get:

[tex]y = 3( - 2) + 6 = 0[/tex]

Another solution is (-2,0)

The solutions are; (0,6) and (-2,0)

Question 2:

The function is

[tex]f(x) = {x}^{6} - {x}^{4} [/tex]

Let us put x=-x,

[tex]f( - x) = {( - x)}^{6} - {( - x)}^{4} [/tex]

This gives:

[tex]f( - x) = {x}^{6} - {x}^{4} [/tex]

We can observe that:

[tex]f(x) = f( - x)[/tex]

This is the property of an even function.

Question 3:

The given function is

[tex]f(x) = {x}^{2} + 3x - 2[/tex]

The average rate of change of f(x) from x=a to x=b is given as:

[tex] \frac{f(b) - f(a)}{b - a} [/tex]

This is the slope of the secant line connecting the two points on f(x)

From x=2 to x=6, the average rate of change

[tex] = \frac{f(6) - f(2)}{6 - 2} \\ = \frac{ {6}^{2} + 3 \times 6 - 2 - {2}^{2} - 3 \times 2 + 2 }{4} \\ = \frac{36 + 18 - 4 - 6}{4} \\ = \frac{44}{4} \\ = 11[/tex]

The average rate of change is 11
