Answers

Answer 1

Answer:

-26 + 4/5d

Step-by-step explanation:

-2/5 ( 15 - 2d + 50)

= -2/5 ( 65 - 2d)

= -2/5 * 65 - (-2/5) * 2d

= -26 - (-4/5d)

= -26 + 4/5d

Answer:

  (b)  x = 6; ...

Step-by-step explanation:

The products of the segment lengths for each chord are the same:

  FA×FB = FC×FD

  FA×3 = 2×9

  FA = 18/3 = 6

  x = 6

__

AB = FA +FB = 6 + 3 = 9

CD = FC +FD = 2 +9 = 11

__

  (x, AB, CD) = (6, 9, 11)

3n + 8 = 53
I don’t understand how to find the n

Answers

Answer:

n=15

Step-by-step explanation:

subtract 8 from both sides to get 3n=45

divide both sides by 3 to solve for n to get n=15

Answer:

n = 15

Step-by-step explanation:

3n + 8 = 53

the first step we are going to do is combine the like terms by moving the constant (8) to the right and subtracting

3n = 45

next step, we are going to isolate the n by dividing by 3 on both sides of the equation

3n divided by 3 is just n and 45 divided by 3 is 15, so we have our answer

Answer:

0.38m

Step-by-step explanation:

1 1/4 m= 1.25m

1.25-0.87m

=0.38m

Answer:

the snake grows 0.38m

Step-by-step explanation:

To find out how much the snake grows you need to find the differences between the length of the snake after and the length before, this means you do:

the grow = the length of the snake after - the length of the snake before

= [tex]1\frac{1}{4}[/tex] - 0.87

= 1.25 - 0.87

= 0.38m

so the snake grows 0.38m

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

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.

4a - 3b + 5 = 5

Step-by-step explanation:

Express the ratios in fractional form

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

4a - 3b = 0

Asif would pay $2400 for a jacket if the price was reduced by 40% what is the the original price of the jacket

Answers

Answer:  $4,000

Step-by-step explanation:

If the price of the jacket is reduced by 40%, it ends up being $2,400.

Assuming the original price is x, the expression will be:

x - (40% * x) = 2,400

x - 0.4x = 2,400

0.6x = 2,400

x = 2,400 / 0.6

x = $4,000

Find the values of x and y that make the quadrilateral a parallelogram.

Answers

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

What is parallelogram and its properties?

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
