Determine the percent of change? original: 50 new: 150.

Reptile [31]

Hi there! The percentage of change is 200%

We can find the percentage of change using the following formula:
$\frac{new-original}{original} \times 100$

When we fill in this formula, we get the following:
$\frac{150-50}{50} \times 100 = \frac{100}{50} \times 100 = 2 \times 100 = 200$

Therefore, the percentage of change is 200%

Which of the following statements must be true about this diagram? Check

Dmitry_Shevchenko [17]

Hey There!!

By looking at the diagram:

m3 = 180-m4

sum of the angles = m1 + m2 + m3 = 180 degrees

substituting the value of m3:

m1 + m2 + ( 180 - m4 ) = 180

m4= 180 - m3

m1 + m2 + (180 - m4) - (180-m4) = 180 - (180-m4)

Hence:

m1 + m2 = m4

so the right answers after concluding from the above calculations is:

A. m1 + m2 = m4

C.m4 is greater than m2

D. m4 is greater than m1
