The given Angles (4x + 2) and (3x + 3) are forming linear pair, so

  • 4x + 2 + 3x + 3 = 180

  • 7x + 5 = 180

  • 7x = 180 - 5

  • 7x = 175

  • x =  \dfrac{175}{7}

  • x = 25

now, let's find Angle DCB :

  • 3x + 3

  • (3 \times 25) + 3

  • 75 + 3

  • 78 \degree

The coordinates of Point A are (6,3). Point B is a reflection of Point A across the y axis. In which Quadrant is point B located
Ksju [112]

point B is located in quadrant II (option B)

Explanation:

Point A: (6, 3) = (x, y)

reflection of point A across the y axis:

The x coordinate will be negative and the y coordinate will remain the same

reflection of point A across the y axis = (-6, 3)

Attaching the graph showing the point after reflection:

Since point B is the reflection of point A.

Hence, point B is located in quadrant II (option B)

What does a formula do in a spreadsheet program?
vekshin1
The answer is D. Think back to the quadratic formula
You would plug in values of a, b, and c to find the zeros of the equations. It would the same way in a spreadsheet program where the cells contain the a, b, and c values but you can have more values and a different equation.

Fractions: three oil tankers together contain 37 5/7 litres of oil. If two tankers have 11 3/14 litres and 12 3/7 litres of oil.
ale4655 [162]

Step-by-step explanation:

It is given that, three oil tankers together contain 37 5/7 litres of oil.

Total volume of oil is \dfrac{264}{7}\ L

If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

Oil in first tanker is \dfrac{157}{14}\ L

Oil in second tanker is \dfrac{87}{7}\ L

Oil in first and second tanker is :

\dfrac{157}{14}\ L+\dfrac{87}{7}\ L=\dfrac{331}{14}\ L

Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )

=\dfrac{264}{7}\ L-\dfrac{331}{14}\ L\\\\=\dfrac{197}{14}\ L

Hence, this is the required solution.
