What is 7 devided by 245 and show work

agasfer [191]

1. Set up the long division.

245/7

2. Calculate 700 ÷ 245, which is 2 with a remainder of 210.

0.02245/7.4.902.10

3. Bring down 0, so that 2100 is large enough to be divided by 245.

0.02245|/.4.902.100

4. Calculate 2100 ÷ 245, which is 8 with a remainder of 140.

0.028245|/.4.902.1001.960140

5. Bring down 0, so that 1400 is large enough to be divided by 245.

0.028245/7.4.902.1001.9601400
6. Calculate 1400 ÷ 245, which is 5 with a remainder of 175.

0.0285245|7.4.902.1001.96014001225175

7. Therefore, 7 divided by 245 approximately equals 0.0285
7÷245≈0.0285

8. Simplify

Figure ABCD is reflected across the x-axis. What are the coordinates of A' , B' , C' , and D' ? Enter your answer in each box.

stealth61 [152]

Answer:

The coordinates of ABCD after the reflection across the x-axis would become:

A'(2, -3)

B'(5, -5)

C'(7, -3)

D'(5, -2)

Step-by-step explanation:

The rule of reflection implies that when we reflect a point, let say P(x, y), is reflected across the x-axis:

x-coordinate of the point does not change, but

y-coordinate of the point changes its sign

In other words:

The point P(x, y) after reflection across x-axis would be P'(x, -y)

P(x, y) → P'(x, -y)

Given the diagram, the points of the figure ABCD after the reflection across the x-axis would be as follows:

P(x, y) → P'(x, -y)

A(2, 3) → A'(2, -3)

B(5, 5) → B'(5, -5)

C(7, 3) → C'(7, -3)

D(5, 2) → D'(5, -2)

Therefore, the coordinates of ABCD after the reflection across the x-axis would become:

A'(2, -3)

B'(5, -5)

C'(7, -3)

D'(5, -2)

The area of a rectangle is (x4 4x3 3x2 – 4x – 4), and the length of the rectangle is (x3 5x2 8x 4). if area = length × width, wh

viva [34]

Answer:

Area = x4 + 4x3 + 3x2 - 4x - 4

Length = x3 +5x2 + 8x + 4

Width = Area / Length.

Performing long division with polynomial.

x4 + 4x3 + 3x2 - 4x - 4 / x3 + 5x2 + 8x + 4 = x-1

Width = x-1
