Answer:

Step-by-step explanation:

28) Perimeter = 10 + 2 + (10 -2) + 3 + (8-2) + 1 + 8 + (1+3+2)

                       = 10 + 2 +  8 + 3 + 6 + 1 + 8 + 6

                        = 44 cm

29) Area = Area of upper block + area of middle block + area of the down block

= (10 * 2) + (2*3) + (1*8)

= 20 + 6 + 8

= 34 cm²

Card sort rational numbers: order from least to greatest. NOTE: (I need the correct answer for an assignment.)
makvit [3.9K]

Answer:

-23 < -22 3/8 < -31/3 < -7.7 < -7 < -6 < -3 < -8/3 < -2.5 < -1 < -1/4 < 0 < 9/8 < 2 < 3 < 5 < 8 < 10 < 11 < 15 < 22 < 23

Showing Work

Using the given inputs:

10 15 8 23 11 5 3 22 2 -1 -3 -7.7 -23 -22 3/8 -7 -8/3 -1/4 9/8 -31/3 -6 -2.5 0

Rewriting these inputs as decimals:

10 15 8 23 11 5 3 22 2 -1 -3 -7.7 -23 -22 3/8 -7 -8/3 -1/4 9/8 -31/3 -6 -2.5 0

10 15 8 23 11 5 3 22 2 -1 -3 -7.7 -23 -22.375 -7 -2.666667 -0.25 1.125 -10.333333 -6 -2.5 0

Sorting this table by decimal values in order from least to greatest:

-23   -22 3/8   -31/3   -7.7   -7   -6   -3   -8/3   -2.5   -1   -1/4   0   9/8   2   3   5   8   10   11   15   22   23

-23 < -22.375 < -10.333333 < -7.7 < -7 < -6 < -3 < -2.666667 < -2.5 < -1 < -0.25 < 0 < 1.125 < 2 < 3 < 5 < 8 < 10 < 11 < 15 < 22 < 23

Therefore, the sorted inputs in order from least to greatest is:

-23 < -22 3/8 < -31/3 < -7.7 < -7 < -6 < -3 < -8/3 < -2.5 < -1 < -1/4 < 0 < 9/8 < 2 < 3 < 5 < 8 < 10 < 11 < 15 < 22 < 23

Find the slant height x of the pyramid shown, to the nearest tenth.<br> 5 mm<br> 9 mm<br> 9 mm
MArishka [77]

The slant height of the pyramid can be calculated using Pythagoras theorem. Therefore, the slant height is 6.7 mm

<h3>How to find slant height of a pyramid?</h3>

The slant height x, can be found using Pythagoras theorem,

Therefore,

c² = a² + b²

where

  • c = hypotenuse
  • a and b are other two legs.

Therefore,

x² = 4.5² + 5²

x² = 20.25 + 25

x² = 45.25

x = √45.25

x = 6.72681202354

x = 6.7 mm
