Only questions 10-12!! Help please!!
butalik [34]

Answer:

Step-by-step explanation:

10) The opposite sides of a parallelogram are equal. It means that

a + 15 = 3a + 11

3a - a = 15 - 11

2a = 4

a = 4/2 = 2

Also,

3b + 5 = b + 11

3b - b = 11 - 5

2b = 4

b = 4/2 = 2

11) The opposite angles of a parallelogram are congruent and the adjacent angles are supplementary. This means that

2x + 11 + x - 5 = 180

3x + 6 = 180

3x = 180 - 6 = 174

x = 174/3 = 58

Therefore,

2x + 11 = 2×58 + 11 = 127 degrees

The opposite angles of a parallelogram are congruent, therefore,

2y = 127

y = 127/2 = 63.5

12) The diagonals of a parallelogram bisect each other. This means that each diagonal is divided equally at the midpoint. Therefore

3y - 5 = y + 5

3y - y = 5 + 5

2y = 10

y = 10/2 = 5

Also,

z + 9 = 2z + 7

2z - z = 9 - 7

z = 2

What number is represented by point P?
likoan [24]

Answer:

0.0057

Step-by-step explanation:

  • Narrow it down.
  • The point P is between 5 * 10^-3 and and 6*10^-3
  • When you go to the bottom line, P is on the 7th division from the left.
  • Going from left to right increases P
  • P is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.
  • One of the answers is 5.7 * 10^-3
  • The other answer is .0057
  • I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.
  • If it is not correct, then 5.7 * 10^-3 is the answer.
