198 cents. Let current price of bread be x cents. 9(x-44) = 7x, 9x - 396= 7x, 2x=396, or x = 198.

Answer:

198 cents or 1.98 dollars.

Step-by-step explanation:

Let x be the current price of the bread in cents,

So, the price of 7 bread = 7x cents,

If the current price of bread dropped by 44 cents,

New price of each bread = x - 44

So, the price of 9 bread = 9(x - 44)

According to the question,

7x = 9(x - 44)

7x = 9x - 396

7x - 9x = -396

-2x = -396

⇒ x = 198

Hence, the current cost of bread is 198 cents or 1.98 dollars.

On a coordinate plane, kite W X Y Z is shown. Point W is at (negative 3, 3), point X is at (2, 3), point Y is at (4, negative 4)
Aloiza [94]

The perimeter of the kite is (10 + 2√53) units if the kite and the coordinates of the kite are point W is at (-3, 3), point X is at (2, 3), point Y is at (4, -4), and point Z is at (-3, -2).

<h3>What is quadrilateral?</h3>

It is defined as the four-sided polygon in geometry having four edges and four corners. Kite is quadrilateral, in which. Two pairs of congruent sides, and it has one pair of opposite congruent angles.

The figure is missing.

On a coordinate plane, kite WXYZ is shown (please refer to the picture)

We have a kite and the coordinates of the kite are:

Point W is at (-3, 3), point X is at (2, 3), point Y is at (4, -4), and point Z is at (-3, -2).

Using the distance formula we can find the distance between coordinates:

\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Distance between W and X:

\rm WX=\sqrt{(2+3)^2+(3-3)^2}

WX = 5 units

Similarly, distance between X and Y:

XY = √53 units

YZ = √53 units

ZW = 5 units

Perimeter = sum of the all sides

Perimeter = 5 + √53 + √53 + 5

Perimeter = (10 + 2√53)  units

Thus, the perimeter of the kite is (10 + 2√53) units if the kite and the coordinates of the kite are point W is at (-3, 3), point X is at (2, 3), point Y is at (4, -4), and point Z is at (-3, -2).

Leena bought 14 yards of wire. How many inches of wire did she buy? (1 yard = 36 inches)
lawyer [7]

Answer:

504

Step-by-step explanation:

So, lets calculator this.

For each yard, there are 36 inches.

There are 14 yards.

To find the amount of inches in this 14 yards, we need to multiply 14 by 36:

14x36

=

504

So there are 504 inches of wire in 14 yards.

Answer:

<u>504</u>

Hope this helps! :)

In a box there are 21 identical pieces that have been enumerated using odd numbers from 5 to 45. How many tiles should be drawn
Orlov [11]

These are the only combinations of exactly 3 tiles that add to 33.

5,7,21

5,9,19

5,11,17

5,13,15

7,9,17

7,11,15

9,11,13

All tiles with numbers above 21 do not help you. 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45. There are 12 of them.

Every three-number combination must have one of the numbers 5, 7, or 9, so if the six numbers from 13 to 21 are picked, in addition to the 12 higher numbers mentioned above, you already picked 18 tiles, and you still have no solution. To obtain the solutions 5,7,21; 5,9,19; 7,9,17; he needs two more numbers in addition to the 18 he already has, so he needs 20 tiles in total to be guaranteed three of them add to exactly 33.

Answer: 20 tiles
