It’s not because if you rotate it a bit you will see that the straight vertical side and straight horizontal side of the triangle form an acute angle, not a 90 degree angle

Answer:

  • No

Step-by-step explanation:

You may find the slopes of the segments EG and FG, the shorter sides of the triangle EFG.

Perpendicular lines have negative-reciprocal slopes.

  • m(EG) = (-3 - 7)/(-6 - (-2)) = -10/-4 = 5/2
  • m(FG) = (-3 - (-8))/(-6 - 7) = 5/-13 = -5/13

<u>The product of the slopes should be -1:</u>

  • 5/2*(-5/13) = - 25/26 ≠ -1

So the answer is No

Answer:

The answer to your question is below

Step-by-step explanation:

1.- ∛27²  = ∛729  = ∛ 3⁶ = 3⁶/³ = 3² = 9

Find the prime factors

    729    3

    243    3

      81     3

      27     3

         9     3

         3     3

          1

2.- 64²/³ = ∛64² = ∛4096 = ∛ 2¹² = 2¹²/³ = 2⁴ = 16

3.- (∛3375)² = ∛3⁶5⁶  = 3⁶/³ 5⁶/³ = 3² 5² = 9 x 25 = 225

4.- (2744)² ¹/³ = ∛2744² = ∛7529536 = ∛2⁶7⁶ = 2⁶/³ 7⁶/³ = 2² 7² = 4 x 49 = 196

5.- 125²/³ = ∛ 15625 = 5⁶/³ = 5² = 25

6.- ∛4096² = ∛16777216 = 2²⁴/³ = 2⁸ = 256

What is the perimeter of the building foundation uncovered by the archaeologists?
ss7ja [257]

Answer:

Wall of Jericho

Step-by-step explanation:

The Wall of Jericho was a Pre-Pottery Neolithic A (PPNA) defensive or flood protection wall suggested to date to approximately 8000 BC.[1] If interpreted as an "urban fortification", the Wall of Jericho is the oldest city wall discovered by archaeologists anywhere in the world.[2] It is built of undressed stones and is located at the archaeological mound known as Tell es-Sultan, in the city of Jericho on the West Bank.

The topic of this article is the unique Neolithic-age stone wall, the earliest one of its kind. Other walls, such as contemporary house walls, or later, Bronze and Iron Age city walls, are only mentioned for the sake of context.

Question... is the commission given 10 times or 3?

If the commission is 10 then

5*(48,000 * .075) + 3*(48,000 * .05) +2*(48,000 * .035)

5*(3600) + 3*(2400) +2*(1680)

= 28560

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If the commission is 3 then (once for first five years, once for the next three,

and once for the last two

(48,000 * .075) + (48,000 * .05) +(48,000 * .035)

=7680

Answer:

Energy equals mass times the

E = mc2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
