9x1/10+6x1/100+4x1/1,000 how can this measurement be written as a decimal

1 answer:

8 0

The above equation can be written as
$\frac{9}{10} + \frac{6}{100} + \frac{4}{1000}$
Then make all the denominators the same
$\frac{900}{1000} + \frac{60}{1000} + \frac{4}{1000} = \frac{964}{1000}$
964/1000 = 0.964

What is m∠PTR? a. 12 b. 40 c. 50 d. 140 HELP!!!

Answer:

m<PTR = 140°

Step-by-step explanation:

First, find the value of x. To find the value of x, derive an equation which you'd use in solving for x.

m<PTQ = (x + 28)°

m<RTS = (2x + 16)°

m<PTQ = m<RTS (vertical opposite angles are congruent)

Therefore:

x + 28 = 2x + 16

Solve for x. Combine like terms

28 - 16 = 2x - x

12 = x

x = 12

Find m<PTQ

m<PTQ = (x + 28)

plug in the value of x

m<PTQ = 12 + 28 = 40°

m<PTR + m<PTQ = 180° (supplementary angles)

m<PTR + 40° = 180° (substitution)

m<PTR = 180 - 40 (subtracting 40 from each side)

m<PTR = 140°

Not all of the student body would have responded therefore her conclusion was incorrect, could be changed to be right by saying 90% of people who responded to a survey said the school colours should be changed.
