Why is the percent increase of 45 to 75 not equal to the percentage crease of 75 to 45 check all that apply.
nevsk [136]

Answer: B and F

Step-by-step explanation:

Since, In the first case original amount = 45

So, the increasing percentage when the original amount increases to 75,

=  \frac{75-45}{45} \times 100 = \frac{30}{45} \times 100= \frac{200}{3} %

In second case original amount = 75

So the decreasing percentage when the original amount decreases to 45,

=    \frac{75-45}{75} \times 100 = \frac{30}{75} \times 100= \frac{40}{1} %

Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because,   \frac{200}{3}\neq \frac{40}{1}

Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because, 75\neq 45

Therefore, Option B and F is correct only.

Kazeer [188]

2000 cm^2

Step-by-step explanation:

we simply round the dimensions of 50.8 cm to 50 cm and 40.6 cm to 40 cm, and we multiply 50*40 cm to get to 2000cm^2 (it is squared because this is area)

Someone help me solve this problem
katrin [286]

Same-side interior angles where a transversal crosses parallel lines are supplementary:

  • 6y +4y = 180
  • 90 +5x = 180

The solutions to these equations can probably be done in your head:

  • y = 180/(6+4) = 18
  • x = (180-90)/5 = 18

The angles at the bottom of the figure, shown as different, are actually the same: 90°.

The angles at the top of the figure, shown as the same, are actually different: 108° on the left, 72° on the right.

The three angles of a quadrilateral are 55,73,105 what is the fourth angle
-Dominant- [34]

Answer:

x = 127°

Step-by-step explanation:

Let A, B and C be the three angles of a quadrilateral such that they are 55, 73, 105 respectively.

We know that, the sum of angles of a quadrilateral is equal to 360°. Let fourth angle be x.

55+73+105+x = 360

233+x=360

x = 360-233

x = 127°

So, the fourth angle is equal to 127°.
