Theo wants to use a cookie recipe that makes 36 cookies but he wants to reduce the number of cookies to 24. If the recipe specifies using 4.5 cups of flour, how much flour should he use?
Answers
Answer:
3 cups
Step-by-step explanation:
[tex]36 : 24 = 4.5 : x[/tex]
where [tex]x[/tex] is the amount of flour he should use
Therefore,
[tex]\frac{36}{24} = \frac{4.5}{x}[/tex]
Cross multiply: [tex]36x = 4.5 \times 24[/tex]
[tex]\implies 36x = 108[/tex]
Divide both sides by 36: [tex]x = 108 \div 36 = 3[/tex]
Therefore, he should use 3 cups of flour

What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
To find the equation of a line given two points, we can use the point-slope form of the equation of a line:
[tex]y - y_1 = m(x - x_1)[/tex]
where m is the slope of the line and (x_1, y_1) are the coordinates of one of the points on the line.
Given the coordinates (0, 0) and (-4, 8), we can find the slope of the line:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
= (8 - 0) / (-4 - 0)
= -2
Now that we have the slope of the line, we can choose one of the points to plug into the point-slope form.
Let's use (0, 0):
[tex]y - y_1 = m(x - x_1)\\y - 0 = -2(x - 0)\\y = -2x[/tex]
Therefore,
The equation of the line that passes through points (0, 0) and (-4, 8) is
y = -2x.

Answers
Polynomials consist of both indeterminates and coefficients. The polynomial that is been represented by the algebra tiles is 2x²-4x -6.
What are polynomials?A polynomial consists of both indeterminates and coefficients and involves mathematical operations such as addition, subtraction, multiplication, and division.
In order to find the polynomial that is been represented by the tiles, we will simply, calculate the number of tiles for each variable,
As we can see in the image,
Number of tiles labeled as x² = 2
Number of tiles labeled as -x = 4
Number of tiles labeled '-' = 6
therefore, the polynomial can be written as 2x²-4x -6.
Hence, the polynomial that is been represented by the algebra tiles is 2x²-4x -6.

Answer:
equation: y = -3x + 10
Step-by-step explanation:
y = -3x + 11
comparing the formula, y = mx + b
We can determine the slope is -3 and y-intercept is 11.
if the line passes (2,4)
use the formula:
y - y1 = m(x - x1)

A pool manager balances the pH level of a pool. The price of a bucket of chlorine tablets is $90, and the price of a pH test kit is $11. The manager uses a coupon that applies a 40% discount to the total cost of the two items. How much money does the pool manager pay for each item?
Answers
Answer:
The pool manager pay for each item is $60.6.
Step-by-step explanation:
Given:
A pool manager balances the ph level of a pool.
The price of a bucket of chlorine tablets is $90, and the price of a ph test kit is $11.
The manager uses a coupon that applies a 40% discount to the total cost of the two items.
Now, to find the money the pool manager pay for each item.
The price of a bucket of chlorine tablets is = $90.
The price of a ph test kit = $11.
So, to get the total price of both items we add both prices:
Total cost of two items = $101.
As, given a coupon that applies a 40% discount to the total cost of the two items.
Now, to get the total cost by applying discount:
Thus, the pool manager pay = $60.6.
Therefore, the pool manager pay for each item is $60.6.

a 65 foot ladder is leaning against a well. Its lower end is 25 feet away from the wall. How much farther away will it be if upper end is moved down 8 feet?
Answers
=====================================================
Explanation:
Check out the diagrams below.
We'll start with the left diagram (marked "before") which is a right triangle with the horizontal leg of 25 feet and hypotenuse 65 feet.
Use the pythagorean theorem to find the vertical side x.
a^2 + b^2 = c^2
25^2 + x^2 = 65^2
625 + x^2 = 4225
x^2 = 4225 - 625
x^2 = 3600
x = sqrt(3600)
x = 60
The top of the ladder is 60 feet high when placed against the wall in this configuration.
------------------
If the upper end is moved down 8 feet, then x-8 = 60-8 = 52 feet is the new height of the ladder. Refer to the "after" in the diagram below.
Like earlier, we'll use the pythagorean theorem to find the missing side.
a^2 + b^2 = c^2
y^2 + 52^2 = 65^2
y^2 + 2704 = 4225
y^2 = 4225 - 2704
y^2 = 1521
y = sqrt(1521)
y = 39
The horizontal distance from the ladder base to the wall is now 39 feet.
Earlier it was 25 feet, so it has increased by 39-25 = 14 feet.
Last Saturday, Ben and Dominic set up a lemonade stand to help their grandmother use

day, the boys had sold 21 pitchers of lemonade. If each pitcher held 9 cups, how many
lemons did Ben and Dominic use?
Answers
Answer:
378 Lemons
Step-by-step explanation:
Because you use 2 lemons for every cup, you first need to find how many lemons per pitcher by multiplying 9 by 2 to get 18, so 18 lemons per pitcher, then multiply that by 21 because that's the total amount of pitchers to get 378 lemons

Two poles meet at the top of the teepee. The angle at which they meet is equal to twice the complement of the angles that the poles form with the ground. What is the measure of the angle at which the two poles meet at the top of the teepee
Answers
The measure of the angle at which the poles meet at the top of the tepee is 180 degrees
Complementary anglesComplementary angles are angles which sum is equals to 90 degrees. Two angles complement each other when there sum is 90 degrees.
The two poles meet at the top of the tepee.
The angle at which they meet is equals to twice the complement of the angles that the poles form with the ground. Therefore,
Complement of the angles that the poles form on the ground = 90°
Then the measure of the angle at which the poles meet at the top of the tepee is as follows:

Step-by-step explanation:
To solve the equation 6 x 27 x 28 x 23 x 3, you can follow these steps:
Start by multiplying the first two numbers: 6 x 27 = 162.
Then multiply the result by the next number: 162 x 28 = 4536.
Continue multiplying by the next number: 4536 x 23 = 104328.
Finally, multiply by the last number: 104328 x 3 = 312984.
The final result is 312984

Step-by-step explanation:
Area of a rectangle = width x heightArea of a triangle = 1/2 x base x heightArea of the rectangle = 11 x 18 = 198 cm²
Area of the triangle = 1/2 x (18 - 7) x (15 - 11) = 22 cm²
Therefore, area of the polygon = 198 + 22 = 220 cm²
Answer:
220 is The Correct Answer
Letter Choice (A)
Step-by-step explanation:
HERE'S MY PROOF AND MY RESEARCH
Area of a rectangle = width x height
Area of a triangle = 1/2 x base x height
Area of the rectangle = 11 x 18 = 198 cm²
Area of the triangle = 1/2 x (18 - 7) x (15 - 11) = 22 cm²
