EVERYONE PLZ PLZ PLZ ANSWER THIS QUESTION

Answer:

[tex]Let~the~percentage~decrease~be~equal~to~y.\\Then,\\0.85x = x-\frac{y}{100}(x)\\or, 0.85x = x-0.01xy\\or, 0.85x = x(1-0.01y)\\or, 0.85 = 1-0.01y\\or, 0.01y = 1-0.85 = 0.15\\or, y =15\\So, ~the~decrease~of~the~price~is~15%.[/tex]

Alternative method:

[tex]Percentage~decrease = \frac{Initial~Rate-Final~rate}{Initial~Rate}(100) \\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\frac{1-0.85}{1}(100) = 0.15(100)=15[/tex]

Answer:

thr percent decrease is 15%

Step-by-step explanation:

you get 1.00 which represent beginning price u subtract the current price 1.00-0.85 you get0.15 which is 15%

Step-by-step explanation:

Multiply top equation by 3 and bottom by 2

6p+9q=-12

6p+10q=-14

Do bottom - top

(6p+10q)-(6p+9q)= (-14) - (-12)

q = -2

6p + 9(-2)=-12 = 6p=18

6p=18-12=6

Answer:

  180 days

Step-by-step explanation:

The formulas for the volume of a cone and a cylinder are ...

  V = πr²h . . . . . volume of a cone

  V = (1/3)πr²h . . . . . volume of a cylinder

Comparing these formulas, you can see that the 6' high cone at the top will have the same volume as a cylinder of the same radius that is 2' high. So, we can simplify the problem to finding the volume of a cylinder that is 66+2 = 68' high.

  V = π(12 ft)²(68 ft) = 9792π ft³ ≈ 30752.5 ft³

When the corn is used at the rate of 170 ft³/day, it will last ...

  (30752.5 ft³)/(170 ft³/day) ≈ 180.96 days

The corn will last 180 days.

_____

Additional comment

In scenarios like this, it is inappropriate to round up. There will be about 162 ft³ of corn left after 180 days, which is not enough for an additional day.

Answer:

c= -6

Step-by-step explanation:

Step-by-step explanation:

The values of x and y that make the quadrilateral a parallelogram are x=3 and y=1.

A parallelogram is a four-sided flat shape with opposite sides that are parallel and equal in length.

Properties are:-

Opposite sides if parallelogram are equal.

The consecutive angles of a parallelogram are supplementary (their sum is 180 degrees).

The diagonals of a parallelogram bisect each other (they intersect at their midpoint).

The slope of the line between the points (4x+6, 4y-3) and (7x-3, 3y+1) is:

slope = (3y+1 - 4y+3) / (7x-3 - 4x-6)

= (-y + 4) / (3x-9)

The slope of the line between the points (7x-3, 3y+1) and (3y+1, 4y-3) is:

slope = (4y-3 - 3y-1) / (3y+1 - 7x+3)

= (y-4) / (7x-3 - 3y-1)

= (y-4) / (7x-3 - 3y-1)

Setting these two slopes equal to each other, we have:

(-y + 4) / (3x-9) = (y-4) / (7x-3 - 3y-1)

Simplifying this equation, we get:

(7x-3 - 3y-1)(-y+4) = (3x-9)(y-4)

-7xy + 28x + 3y^2 - 13y - 7 = 3xy - 12x - 9y + 36

Rearranging and simplifying, we get:

3x + 2y = 11 ... (1)

Similarly, we can find the slope of the line between the points (4x+6, 4y-3) and (3y+1, 4y-3) and the slope of the line between the points (7x-3, 3y+1) and (4x+6, 4y-3) and set them equal to each other. We get another equation:

4x - 3y = 9 ... (2)

We now have two equations with two variables. Solving for x and y, we get:

x = 3

y = 1

B. z < 6 because 6 + 2 = 8 but z + 2 < 8.

Answer:

C. (x, x2 − 3x − 28) for all real numbers

Function graphs are graphs of solution equations for y! In this instance, f(x) = x² -3x -28 is the graph.

⇒f(x) = x² − 3x − 28

Solving equation:

⇒f(x) = x² − 3x − 28

⇒f(x) = x² − (7−4)x − 28

⇒f(x) = x² − 7x+4x − 28

⇒f(x) = x(x −7) +4(x −7)

⇒f(x) = (x −7) (x+4)

Answer:

4a - 3b + 5 = 5

Step-by-step explanation:

Express the ratios in fractional form

[tex]\frac{a}{3}[/tex] = [tex]\frac{b}{4}[/tex] ( cross- multiply )

4a = 3b ( subtract 3b from both sides )

4a - 3b = 0
