Find the supplement and complement of θ=3π/5.

Answers

Answer 1
Answer: we shall convert first the angle in radians to degrees for convenience. The conversion is equal to 108 degrees. In this case, this is a second quadrant angle. The supplement angel is 180 - 108 equal to 72 degrees which is equal to 2 pi/5 . The complement is the same as the supplement

What is (7/12)/(5/9)? In simplest form..

Answers

(7)/(12) / (5)/(9) =

Change the division to multiplication through the reciprocal of the number being divided. 

(7)/(5) * (9)/(5) =  (21)/(20)

As mixed number:

1 (1)/(20)
7/12 times 5/9 equals 35/108. It is automatically in simplest form.

What is 1/10 + 1/4 + 1/5+2/15? A.41/60 B 6/41 C 11/12 D 1/7

Answers

an easy common denominator is 60 bc 15*4=60 and everything else can equal 60 too so: 
6/60+ 15/60+ 12/60+ 8/60 = 41/60 (you only add the numerator numbers) usually you would reduce the end result too but 41 is a prime number so you cant 
1/10 + 1/4 + 1/5 + 2/15.

LCM of 10, 4, 5, and 15 = 60

1/10 = 6/60        1/4 = 15/60      1/5 = 12/60    2/15 = 8/60

= 6/60 + 15/60 + 12/60 + 4/60 = (6 + 15 + 12 + 8) / 60 = 41/60

What is the value of this expression 210/7-18+4*6-20
A)112
B)76
C)28
D)16

Answers

Following the MDAS rule, where it is necessary to do multiplication or division processes first (whichever of the 2 is encounter first in the equation) before proceeding to addition and subtraction, the expression can be solved, and is done as follows:

210/7 - 18 + 4*6 - 20

Doing division and multiplication first:
30 - 18 + 24 - 20

Simplifying:
16

Therefore the answer among the choices is D.
D) 16
(210)/(7) -18+4*6-20
=30-18+24-20
=30+24-(18+20)
=54-38
=16

Matthew had the following times in two races:3.032 minutes and 3.023 minutes .Use >,<,or = to make the sentence true

Answers

3.032 > 3.023
3.032 is greater because instead of the 2 in 3.023, there is a greater value in the second number, 3.

Hope this helps :)
3.032 > 3.023 because 32 is bigger than 23.
