Mathematics
1 answer:
melomori [17]2 years ago
5 0

Answer:

D

The absolute value of a number is the actual distance of the number from zero. So, it is always a positive number. No negative value.

A) I -4.5I = 4.5    TRUE

B) I 0I  < I -45I   TRUE  

Reason: 0 < 45

C) I 45 I > 0         TRUE

D) I4.5 I > I - 45 I     FALSE

Reason: 4.5is not greater than 45

Triangle EFG in which segment EF measures 3 units and segment FG measures 5 units
Softa [21]

Answer:

Yes

Step-by-step explanation:

It can be 6 units. The rule relating to the sides of the triangle is that you should be able to add two sides and get a length that is longer than the third side. You usually add the lower two numbers because it basically says that it will work for all sides but, if you're still in doubt you just have to compare the numbers.

For Example

3+5 is greater than 6

5+6 is greater than 3

6+3 is greater than 5.

All of these makes sense so 6 can be a possible answer.

100 POINTS PLEASE HELP ME 100 POINTS (make fullscreen)
Anit [1.1K]

Answer:

  • 1) 64, 2) 6, 3) 26, 4) 33

Step-by-step explanation:

<h3>#1</h3>

<u>Sum of interior angles is 180</u>

  • 70 + 46 + x = 180
  • 116 + x = 180
  • x = 64
<h3>#2</h3>

<u>Sum of interior angles is 180</u>

  • 84 + 7x + 1 + 9x - 1 = 84
  • 16x + 84 = 180
  • 16x = 96
  • x = 6
<h3>#3</h3>

<u>Vertical angles are same, the sum of remaining angles is same for both triangles:</u>

  • 35 + 25 = 34 + x
  • 60 = 34 + x
  • x = 60 - 34
  • x = 26
<h3>#4</h3>

<u>Exterior angle is same as the sum of non-adjacent interior angles:</u>

  • 5x - 7 + 6x + 3 = 84
  • 11x - 4 = 84
  • 11x = 88
  • x = 8
  • m∠G = 5x - 7 = 5*8 - 7 = 40 - 7 = 33

If log(base4)x=2.5 and log(base Y)125=-3/2, find the numerical value of x/y, in simplest form.
Naya [18.7K]
X = (2^2)^(2.5) 
<span>x = 2^(2 * 2.5) </span>
<span>x = 2^5 </span>
<span>x = 32 
</span>y^(-3/2) = 125 
<span>y^(-3) = 125^2 </span>
<span>y^(-3) = (5^3)^2 </span>
<span>y^(-3) = (5^2)^3 </span>
<span>y^(-3) = 25^3 </span>
<span>y = 25^(-1) </span>
<span>y = 1/25 </span>
