Answer:

See Below.

Step-by-step explanation:

Paragraph Proof:

We are given that ∠1 ≅ ∠4. ∠1 and ∠4 are alternate exterior angles. Since they are congruent, by the Alternate Exterior Angles Converse, the two lines being cut by the transversal must be parallel. Then by the Alternate Interior Angles Theorem, ∠3 ≅ ∠2.

2-Column Proof

 Statements                                               Reasons:

1) \angle 1\cong \angle 4                                                    Given

2) \text{The two lines are parallel}                        Alternate Exterior Angles Converse

3) \angle 3\cong \angle 2                                                  Alternate Interior Angles Theorem

I would write a flowchart as well, but unfortunately, I never learned it that way.

The manager of a grocery store wants to determine the average amount of money spent at his store as it compares to the average d
andrey2020 [161]
For the manager's grocery store, the average mean to the nearest cent is 37.6 while the competitor's store has an average of 48.53. However, the store that has a mean that better represents its data is the first store, the manager's store, because the values are more close to the mean as compared to the other store which has extreme values far from the mean or scattered from the mean.

A mason's assistant's rate of pay is $0.95 per cubic foot of earth moved. he digs a trench 2.5 ft. wide by 2 ft. deep by 150 ft.
Romashka [77]
Well well if he gets paid. $0.95 per ft^3 this equates to:
pay = $0.95 * volume

because the volume is the amount of ft^3

a trench shape would be considered rectangular. The the volume of rectangle is :
volume = length * width * height

so:
v = 2.5 ft * 2 ft * 150 ft
v = 750 ft^3

so:
pay = 0.95 $/ft^3 * 750 ft^3

p = $712.50
