Answer:

193 packets

Step-by-step explanation:

Each morning they order with a shipping fee of $10 daily.

Considering they order all 7 days of the week, so the total shipping fee for the week would be:

7 * $10 = $70

Their budget for the week is $554, out of which $70 is for shipping for the week, so remaining balance would be:

554 - 70 = $484

This 484 dollars are for coffee packets that cost $2.50 each, so the number of packets would be:

484/2.50 = 193.6

You can't order fractional packets so 193 packets is the max in this budget

Answer:

20 cups

Step-by-step explanation:

16 ounces = 1 pound

8 ounces = 1 cup

16 ounces = 2 cups

1 pound = 2 cups

10 pounds = 20 cups

Answer:

20 cups

Step-by-step explanation:

Think

1 pound is 16 oz

So each cup has 8 oz

This you have to convert the 10 pound into ounces

Which then equals 160 ounces

Now divide 160 ounces by 8 and you get..

You get 20

So, 10 pounds of apples fit into 20 cups

Answer:   (x-7)/(x-5)

The (x+1) terms divide and cancel out due to the rule that x/x = 1, when x is nonzero. In that rule, we can replace 'x' with any algebraic expression we want.

Answer:

When Sum of square of two Sides is equal to square of third side of triangle.

Step-by-step explanation:

Given:

Three side length of triangle are given we need find the which value to substitute for a, b, c in Pythagoras theorem.

First we will find the squares of all length, then we will check which two square of side are equal to square of third side as per Pythagoras theorem.

Hence the two side would according be a and b and third side will become c.

For example if length of triangle  is given as 6 cm, 8 cm and 10 cm.

We will first take square of all

[tex]6^2=36\\8^2=64\\10^2=100[/tex]

Now we can see that

[tex]36+64=100\\6^2+8^2=10^2[/tex]

Now by Pythagoras theorem.

[tex]a^2+b^2=c^2[/tex]

Hence we can say a = 6 cm, b = 8 cm, c= 10 cm  

The Pythagorean Theorem is specifically applicable to right-angled triangles and states that:

[tex]\[a^2 + b^2 = c^2\][/tex]

Theorem, follow these steps:

1. Identify the longest side: The hypotenuse  c is always the longest side in a right-angled triangle.

2. Assign the longest side to c : Among the three given side lengths, the one with the greatest value should be assigned to c .

Example

Suppose you are given three side lengths: 5, 12, and 13. To determine which lengths correspond to  a ,  b , and c :

1. Identify the longest side: Among 5, 12, and 13, the longest side is 13.

2. Assign the longest side to c : So, c = 13 .

3. Assign the remaining sides to  a  and  b: Thus,  a and  b can be 5 and 12, respectively (or vice versa).

Verify using the Pythagorean Theorem:

[tex]a^2 + b^2 = c^2[/tex]

[tex]5^2 + 12^2 = 13^2[/tex]

25 + 144 = 169

169 = 169

Since the equation holds true, the side lengths 5, 12, and 13 do indeed form a right-angled triangle, with 13 being the hypotenuse.

General Case

When given any three side lengths x ,  y , and z :

1. Determine the longest side and assign it to c .

2. The remaining two sides are a  and b

3. Check if [tex]\( a^2 + b^2 = c^2 \)[/tex] to verify if the triangle is a right-angled triangle.

By following this process, you can correctly identify the sides to substitute into the Pythagorean Theorem.

Answer:

k = -5

Step-by-step explanation:

2(7k + 1) - 5(3k + 3) = 1 - 2k + 6 + 5k

At first, we will break the parenthesis by multiplying by the adjacent number. As we know, (+) x (-) = (-) and (-) x (-) = (+) [Algebraic operation]

or, (2*7k) + (2*1) - (5*3k) - (5*3) = (1 + 6) + 5k - 2k

or, 14k + 2 - 15k - 15 = 7 + 3k

Interchanging the values, we can get,

or, 14k - 15k - 3k = 7 + 15 - 2

or, 14k - 18k = 22 - 2

or, -4k = 20

or, k = 20/(-4)

or, k = -5

Therefore, the answer is -5

Answer:

slope = - 2, y- intercept = - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 6x + 3y = - 3 into this form by subtracting 6x from both sides

3y = - 6x - 3 ( divide all terms by 3 )

y = - 2x - 1 ← in slope- intercept form

with slope m = - 2 and y- intercept c = - 1

The original width of the rectangle is 8 cm and the original length is 18 cm. These dimensions are found by setting up an equation based on the change in area when both dimensions are reduced by 2 cm.

Finding Original Dimensions of a Rectangle

Let's denote the width of the rectangle as w, and the length will then be w + 10 cm. The area of the original rectangle is w(w + 10) square centimeters. Now, by decreasing each dimension by 2 cm, the new width becomes w - 2 cm and the new length becomes (w - 2) + 10 cm = w + 8 cm. The area of the new rectangle is (w - 2)(w + 8) square centimeters.

The problem states that the area of the rectangle is decreased by 48 cm2 when the dimensions are reduced. This gives us the equation:

w(w + 10) - (w - 2)(w + 8) = 48

Expanding the terms and solving for w will provide us with the width of the original rectangle. After finding w, we can calculate the original length by adding 10 cm to the width. To solve for w, we proceed with the calculation:

[tex]w_2 + 10w - (w_2[/tex] + 6w - 16) = 48

w2 + 10w - w2 - 6w + 16 = 48

4w + 16 = 48

4w = 32

w = 8 cm.

Therefore, the original width is 8 cm and the original length is 18 cm (that is, 8 cm + 10 cm).

[tex]9c-7=7c-11\qquad\text{add 7 to both sides}\\\\9c-7+7=7c-11+7\\\\9c=7c-4\qquad\text{subtract}\ 7c\ \text{from both sides}\\\\9c-7c=7c-7c-4\\\\2c=-4\qquad\text{divide both sides by 2}\\\\\dfrac{2c}{2}=\dfrac{-4}{2}\\\\c=-2[/tex]

Answer:

2

Step-by-step explanation:

Simplifying

9c + -7 = 7c + -11

Reorder the terms:

-7 + 9c = 7c + -11

Reorder the terms:

-7 + 9c = -11 + 7c

Solving

-7 + 9c = -11 + 7c

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-7c' to each side of the equation.

-7 + 9c + -7c = -11 + 7c + -7c

Combine like terms: 9c + -7c = 2c

-7 + 2c = -11 + 7c + -7c

Combine like terms: 7c + -7c = 0

-7 + 2c = -11 + 0

-7 + 2c = -11

Add '7' to each side of the equation.

-7 + 7 + 2c = -11 + 7

Combine like terms: -7 + 7 = 0

0 + 2c = -11 + 7

2c = -11 + 7

Combine like terms: -11 + 7 = -4

2c = -4

Divide each side by '2'.

c = -2

Simplifying

c = -2

The correct equation for the booster club aiming to earn $200 per match from student and adult tickets priced at $4 and $8, respectively, is 4x + 8y = 200. This represents the sum of $4 per student ticket (x) and $8 per adult ticket (y) sold to reach the goal.

To solve the problem presented by the high school soccer booster club, we need to formulate a linear equation that represents their goal for ticket sales revenue from students and adults. The tickets are priced at $4 for students and $8 for adults. If we let x represent the number of student tickets sold and y the number of adult tickets sold, the total revenue T would be expressed as the sum of $4 per student ticket and $8 per adult ticket.

The booster club aims to earn $200 per match, which gives us the equation for their goal: 4x + 8y = 200. Here, the 4 and 8 are the prices of the tickets for students and adults, respectively, and x and y are the numbers of tickets sold. This clearly aligns with option b from the choices you've provided.

To illustrate with an example similar to your situation, a tutoring school equation of y = 3000x + 500  combines a one-time enrollment fee of $500 with a tuition of $3000 per year. In this case, y represents the total cost of attendance and x the number of years a student is enrolled.

To find the milliliters of acid in the solution, multiply the total volume of the solution by the acid percentage.

Explanation:

To find the milliliters of acid in the solution, we first need to calculate the volume of acid. We know that 13.2% of the solution is acid, so we can calculate the volume of acid by multiplying the total volume of the solution by the acid percentage:

Volume of acid = 357 mL * 0.132 = 47.124 mL

Rounding to the nearest tenth, we get:

Volume of acid = 47.1 mL

Answer:

The quantity of large frames is 7

The quantity of small frames is 13

Step-by-step explanation:

Given as :

The price of each large frames = $ 10

The price of each small frames = $ 5

The total number of both frames bought = 20

The price for both the frames = $ 135

Now,

Let the quantity of large frames = L

And The quantity of small frames = S

So , According to question

The total number of both frames bought = 20

Or, The quantity of large frames + the quantity of small frame = 135

Or, L + S = 20         ......A

And $ 10 L + $ 5 S = $ 135                         ................B

Or, $ 10× ( L + S ) = $ 10× 20

Or, $ 10 L + $ 10 S = $ 200

(  $ 10 L + $ 10 S ) - ( $ 10 L + $ 5 S ) = $ 200 - $ 135

Or , ( $ 10 L - $ 10 L ) + ( $ 10 S - $ 5 S ) = $ 65

Or, 0 + 5 S = 65

∴  S = [tex]\frac{65}{5}[/tex]

I.e S = 13

So, The quantity of small frames = S = 13

Put the Value of S in eq A

So , L + S = 20

Or, L = 20 - S

Or, L = 20 - 13

∴   L = 7

So, The quantity of large frames = L = 7

Hence The quantity of large frames is 7

And   The quantity of small frames is 13   Answer
