Answer:

  387,420,489

Step-by-step explanation:

The order of operations tells you that exponential terms must be evaluated first, before multiplication:

  (9^-3)(9^12) = (1/729)(282,429,536,481) = 387,420,489

__

The rules of exponents tell you that this can be simplified before it is evaluated.

  (9^-3)(9^12) = 9^(-3+12) = 9^9 = 387,420,489

Three friends recorded, in different units, the lengths of the hopscotch paths they made.
ivann1987 [24]

From the options given, Dustin's hopscotch path was the longest in comparison to the other two friends.

<h3>How to find out who had the longest path?</h3>
  • Make sure all distances use the same units.
  • If necessary convert the distances.
  • Compare the distances.

Based on this, let's make sure all distances are in feet.

  • Cassey: 94 feet

  • Jasmin: 1100 in or 91.66 feet
  • Each inch is equivalent to 0.0833
  • 1100 x 0.0833 = 91.66

  • Dustin: 32 yards or 96 feet
  • 1 yard = 3 feet
  • 32 x 2 = 96 feet

Based on this, the person with the longest path is Dustin.

17.

x = -2 is not a solution of -1 < x < 5 because -2 < -1 (-1 < -2 < 5 FALSE).

18.

m = 5 is a solution of 5 ≤ m because 5 ≤ 5 ( 5 ≤ m → m ≥ 5 greater than 5 or equal 5, 5 is equal 5)

19.

k = 10 is not solution of 2k - 3 < 1 because:

put the value of k to the inequality:

2(10) - 3 < 1

20 - 3 < 1

17 < 1 FALSE

A triangle has angle measurements of 56°, 54°, and 70°. What kind of triangle is it?
alexira [117]

Answer:

Right, I am an idiot so i might be wrong

Step-by-step explanation:

Every triangle has three angles which sum to 180 degrees.

There are three types of triangles based on the measures of its angles.

Right Triangle - Has one 90 degree angle

Acute Triangle - All angles less than 90 degrees

Obtuse Triangle - One angle greater than 90 degrees

In this example we are given 2 angles and must find the measure of the 3rd.

a + 56 + 34 = 180

a + 90 = 180

a = 90

Therefore, it is a Right Triangle.
