Find the difference 4 1/3 - 2 2/3
Eduardwww [97]

Answer:

1 2/3

Step-by-step explanation:

convert to improper fraction:

13/3 - 8/3

then solve:

13/3 - 8/3 = 5/3

convert back to a mixed number (unless your not supposed to, if that is the case then "5/3" is your answer):

"1 2/3" is "5/3" as a mixed number.

so your answer (as a mixed number) is:

"1 2/3"

Find the missing side length. Leave your answer as a radical in the simplest form
seraphim [82]

9514 1404 393

Answer:

  x = y = 12

Step-by-step explanation:

A right triangle with a 45° angle is an isosceles right triangle. That means the legs are both the same length. The side ratios of such a triangle are ...

  1 : 1 : √2

Multiplying these ratios by 12 gives ...

  12 : 12 : 12√2 = x : y : 12√2

The side lengths x and y are both 12 units.

What is the area of the poster board that she has left
steposvetlana [31]
Find the area of the parallelogram, find the area of the triangle, then subtract the triangle's area from the area of the parallelogram.

Area of Parallelogram:
A= base * height
A= 20 in * 10 in
A= 200 in^2

Area of Triangle:
A= 1/2 base * height
A= 1/2 (10 in)(9 in)
A= 1/2 (90)
A= 45 in ^2

Area of Poster Left:
subtract the difference
A= Parallelogram Area - Triangle Area
A= 200 in^2 - 45 in^2
A= 155 in^2

ANSWER: 155 in^2 is the area of the poster board she has left.

Hope this helps! :)
