What is 2/15 closest to 0, 1/2, 2
Brums [2.3K]
0 < 2/15 < 1/2 < 2

Each number is decimal form:
0 = 0.00
2/15 = 0.13(repeating 3)
1/2 = 0.50
2 = 2.00

How far from each number closet to 2/15:
0.13 - 0 = 0.13
0.50 - 0.13 = 0.37

Find the shaded area of the figure. Please help would really appreciate it
Alisiya [41]
<h3>Answer:  120 square cm</h3>

==========================================================

Work Shown:

Let,

  • A = area of unshaded rectangle (the 6 by 10 rectangle)
  • B = area of the unshaded triangle (that has the "8 cm" inside it)
  • C = area of parallelogram
  • D = shaded area = C - (A+B) = C - A - B

We can see that A = 60 since the rectangle has base 10 and height 6, so 10*6 = 60.

The upper horizontal part of the parallelogram is 10+8 = 18 cm long. This means the bottom horizontal part of the parallelogram is the same length. The bottom portion shows 9 cm until we reach the triangle. This means that 18-9 = 9 cm is the base of the unshaded triangle (that has the "8 cm" inside it).

That triangle has area of 0.5*base*height = 0.5*9*8 = 36 square cm. So B = 36

The parallelogram has base 18 cm and height 12 cm, so it has area of 18*12 = 216. This means C = 216

We can then finally compute the value of D

D = C - A - B

D = 216 - 60 - 36

D = 120 square cm

A large concrete mixing machine can mix a certain amount of concede in 12 hours, while a smallet one can mix
Andrews [41]

Answer:

[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1

(5/60 + 3/60)x = 1

(8/60)x = 1 we can reduce 8/60 by dividing out a 4

(2/15)x = 1 x both sides by 15/2

x = 15/2

x = 7 1/2 or 7.5 hours
