I need help with no.7

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

Answer:

(-4(x-2))/((x+2)|(x-4)|)

Step-by-step explanation:

You were so close. I stared at your problem for a

long time when you first posted it. I used a graphing utility to experiment. Your denominator was perfect for getting the vertical asymptotes in the right place. The y-intercept worked. The x-intercept was exactly right. I couldn't get the far right piece of the curve to reflect down in the fourth quadrant.

Hours later...suddenly BAM! ABSOLUTE VALUE pops into my head.

I always thought the numerator should be negative, so that middle portion of the curve that looks like a cubic would start "up to the left" and end "down to the right" But those left and right curves should be like mirror images of each other sort of. So I tried the absolute value and it worked! Good luck with your work. Hope this helps a little.

Answer:

378 Lemons

Step-by-step explanation:

Answer:

Y=-2X

Step-by-step explanation:

The equation of the line that passes through points (0, 0) and (-4, 8) is

y = -2x.

Option F is the correct answer.

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.

Answer:

A = 220 cm²

Step-by-step explanation:

Area 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

Therefore, area of the polygon = 198 + 22 = 220 cm²

=====================================================

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.

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.

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)

y - 4 = -3(x - 2)

y = -3x + 6 +4

y = -3x + 10

​

Factor 4−x^2

1/x−2  +  4/(x−2)(−x−2)

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x−2 and (x−2)(−x−2) is (x−2)(−x−2).

Multiply :  1/x−2 TIMES −x−2/−x−2

−x−2/(x−2)(−x−2)  +  4/(x−2)(−x−2)

​Since  −x−2/(x−2)(−x−2) and  4/(x−2)(−x−2)  have the same denominator, add them by adding their numerators.

−x−2+4​/(x−2)(−x−2)

Combine like terms in −x−2+4.

−x+2/(x−2)(−x−2)

Extract the negative sign in −x+2.

−(x−2)/(x−2)(−x−2)

Cancel out x−2 in both numerator and denominator.

Polynomials consist of both indeterminates and coefficients. The polynomial that is been represented by the algebra tiles is 2x²-4x -6.

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.

It can be deduced from the multiplication that the minimum number of water stations for this race will be 28.

Your information isn't complete as the figures aren't provided. Therefore, an overview will be given.

In this case, let's assume that there are 14 routes and that there will be a water station at the beginning and end of the routes.

From the scenario, if the racers are to run through all the routes, the number of water stations will be the value of 14 multiplied by 2. This will be:
