Answer:

82 units

Step-by-step explanation:

There are multiple ways to go about solving this problem (solving by calculating the areas of the individual, smaller shapes), but I recommend solving it by first calculating the area of the entire figure (96 units - 12 * 8 - length * width ((formula for the area of a rectangle)) and then subtracting the area of the missing part from this value.Assume the opposite sides are equal in value (see picture for work) and subtract the given values (4 and 5) from 8 and 12 to get the measurements to find the triangle (the missing part).You get 7 and 4 and now you use the formula for the area of a triangle to get the area. (7*4)/2, which gives you 14 units.Subtract 14 (area of missing value) from 96 (area of total value) to get your final answer, 82 units!

Decide whether there is enough information to prove that a∥b. If so, state the theorem you would use.

Answers

Answer: C) Yes, Alternate Exterior Angles Converse

The two red angles are on the outside of the lines a and b, so they are considered exterior. They alternate on either side of the transversal line. So we consider those red angles to be alternate exterior angles. We'll use the alternate exterior angles converse to prove the lines parallel. That converse states: "If alternate exterior angles are congruent, then the lines are parallel".

Solve. Express your answer as a mixed number. 5 feet= ______ yards Solve. I need an explanation on how to put it as a mixed number and how to solve it.

Answers

Answer: 5 feet= __5/3 0r 1 2/3____ yards

Step-by-step explanation:

Step 11 yard = 3 feet

3 feet = 1 yard

5 feet = 5feet  x 1 yard/ 3feet

= 5/3yards  

Step 2  To convert 5/3 yards   to a mixed fraction,

1. We first Divide the numerator, 5  by the denominator, 3 giving us  a whole number and a remainder

5/3 = 1 remainder 2

2.then we write the whole number and put the remainder 2 above the denominator 3 giving us

5/3 = 1 2/3

such that when you multiply the mixed fraction 3 x 1  and add 2 it gives back the improper fraction of 5/3
