9 servings are there in 22.5 ounces of trail mix.

Given:

The weight of one serving of trail mix is 2. 5 ounces.

1 serving = 2.5 ounces

Number of servings = 22.5 ounces / 1 serving

= 22.5 / 2.5

= 225/10/25/10

= 225/25

= 9 servings.

Therefore 9 servings are there in 22.5 ounces of trail mix.

Step-by-step explanation:

simplify [tex]\sqrt{20}[/tex] and [tex]3\sqrt{50}[/tex]

 [tex]\sqrt{20}[/tex] simplifies into [tex]\sqrt{5}[/tex]

 so [tex]\sqrt{20}[/tex] =  [tex]\sqrt{4} \sqrt{5}[/tex]

we can simplify [tex]\sqrt{4[/tex] into a whole number

[tex]\sqrt{4[/tex] =2

          =   2[tex]\sqrt{5}[/tex]

   [tex]\sqrt{50[/tex] simplifies into [tex]\sqrt{2[/tex]

   so [tex]\sqrt{50[/tex] =3( [tex]\sqrt{25} \sqrt{2}[/tex])

we can simplify [tex]\sqrt{25}[/tex] into a whole number

[tex]\sqrt{25[/tex] = 5

Step-by-step explanation:

Jane made a mistake in her third step. The solution of the equation is x = - 13 / 18

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

The solve the equation to detect where Jane made the mistake in her solution.

-3(4x - 5) = 6(x + 3) + 10

open the brackets on both sides of the equation

-3(4x - 5) = 6(x + 3) + 10

- 12x + 15 = 6x + 18 + 10

- 12x + 15 = 6x + 28

subtract 6x from both sides of the equation

- 12x + 15 = 6x + 28

- 12x - 6x + 15 = 6x - 6x + 28

-18x + 15 = 28

subtract 15 from both sides of the equation

-18x + 15 = 28

-18x + 15 - 15 = 28 - 15

-18x = 13

divide both sides by - 18

x = 13 / -18

x = - 13 / 18

Therefore, jane made a mistake in her third step. She didn't add 18 and 10 together on the right side of the equation.

The input of a function that can be controlled is the independent variable while the output is the dependent variable thus "Number of hours" and "D" are independent while the amount of muscle mass is the dependent variable.

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

An input variable that we can control and manage is said to be an independent variable.

For example in function y = f(x) here we can control variable x so it will be an independent variable.

As per the given,

The number of hours we can spend so will be an independent variable.

The input D will be the independent variable.

The amount of mass muscles depends on age so it will be the dependent variable.

Hence "Number of hours" and "D" are independent while the amount of muscle mass is the dependent variable".

The length of the side AC = 9.5 units

The length of the side BC = 5.1 units

The opposite angle of AB is angle C, the opposite angle of AC is angle B and the opposite angle of BC is angle A

We know length of the line is BC which is 5.1 units which is the smallest side of the triangle. Then the opposite angle of BC will be the smallest angle in the triangle ABC

The opposite angle of the side BC is angle A, which is the smallest angle in the triangle

Answer:

Step-by-step explanation:

1a) The number of whole servings Susan can make from 4.25 pounds of flour if one serving uses ²/₃ is 6.

1b) The quantity of flour Susan has after making 6 servings is ¹/₄ pounds.

2) Garrison can drink ⁷/₈ gallons of lemonade each of the next six days.

3) The student council sold 122 bags of chips.

4) If a container can hold 3¹/₃ ounces of peanuts, 5 containers will hold 16²/₃ ounces.

5) The number of people at the football game (400) last night who were not wearing orange and black is 240.

6) The number of long sleeves in Jordan's outfits is 45.

The numbers and values can be determined using suitable mathematical operations.

The basic mathematical operations used include division, subtraction, and multiplication.

1) The total quantity of flour available = 4.25 pounds

The amount of flour required per serving = ²/₃ pounds

The number of servings from 4.25 pounds = 6³/₈ servings (4.25 ÷ ²/₃)

= 6 servings.

Quantity of flour left = ¹/₄ pounds [4 - 6(²/₃)]

2) The number of lemonades available = 5.5 gallons

The quantity Garrison took on Monday = ¹/₄ gallons (0.25)

The remaining number of gallons = 5.25 gallons (5.5 - 0.25)

The gallons for the remaining 6 days = ⁷/₈ gallons (5¹/₄ ÷ 6)

3) The total amount realized from sales = $73.20

The unit price per bag of chips = $0.60

The units sold = 122 ($73.20 ÷ $0.60)

4) The ounces of peanuts per container = 3¹/₃

The number of containers = 5

The ounces of peanuts for 5 containers = 16²/₃ ounces (3¹/₃ x 5)

5) The total number of people at the game = 400

The proportion of people wearing orange and black = ²/₅

The proportion of people not wearing orange and black = ³/₅ (1 - ²/₅)

The number of people not wearing orange and black = 240 (400 x ³/₅)

6) The total number of outfits in Jordan's closet = 200

The proportion of shirts = ³/₄

The proportion of long sleeve shirts = ³/₁₀

The number of long sleeve shirts = 45 (200 x ³/₄ x ³/₁₀)

By evaluating the function in x = 1 we get:

C(1) =  95.16

This means that the per capita consumption of all poultry in 2015 was 95.16 pounds.

Here we have the linear function:

C(x) = 2.97*x+ 92.19

We know that it models the consumption of all poultry in a country as a function of x, the number of years since 2014.

Then C(1) will be the consumption of all poultry in that country one year after 2014 (this would be on 2015).

To evaluate we just need to replace the variable x in the equation by 1, we will get:

C(1) = 2.97*1+ 92.19 = 95.16

Answer:

x = 30 degrees

y = 15 degrees

z = 150 degrees

Step-by-step explanation:

Finding x:

2x + 90 + x = 180

3x + 90 = 180

3x = 90

x = 30

x and 2y are alternate interior angles, which means that they are congruent:

x = 2y

30 = 2y

15 = y

x and z are same side interior angles, which means that they are supplementary:

x + z = 180

30 + z = 180

z = 180 - 30

z = 150

Answer: A loss of 6 dollars

Step-by-step explanation:

Step 1 is to determine how many eggs she purchased:

3 dozen eggs * 12 eggs per dozen = 36 eggs purchased

Step 2 is to find the cost of the eggs purchased using the information you gave:

(36 eggs / 6) * 10 dollars = $60 purchase price

Step 3 is to find out how many eggs broke which is calculated like this:

36 total eggs * .25 = 9 broken eggs

Step 4 is to find how much money she made from selling the remaining eggs:

(36 total eggs - 9 broken eggs) * $2 per egg = $54 resale

Step 5 is finding the profit or loss:

$54 resale price - $60 purchase price = $ -6 (aka a 6 dollar loss)
