(1/2)^x=2^-x could anyone tell me why​

Answer: C. 75

Concept:

Here, we need to know the idea of quadrilaterals in a circle.

The opposite angles of quadrilaterals in a circle (cyclic quadrilaterals) are supplementary, meaning they add up to 180°

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

Given information

The opposite angle of b = 105°

Given expression

b + opposite angle of b = 180°

Substitute values into the expression

b + 105 = 180

Subtract 105 on both sides

b + 105 - 105 = 180 - 105

b = 75°

Hope this helps!! :)

Answer:

24

Brainliest, please!

Step-by-step explanation:

68 + (5t - 8) = 180

5t + 60 = 180

5t = 120

t = 24

Answer:

24

Step-by-step explanation:

5t-8 and 68 are the angles of a straight line so their addition will be180°.

5t-8 + 68 = 180

5t + 60 = 180

5t = 180-60

5t = 120

t= 120/5

t= 24

Answer:

-135, -134, -133

Step-by-step explanation:

Hi there!

Let x be equal to the first integer in the set of three consecutive integers.

Let x+1 and x+2 be the consecutive integers.

We're given that they have a sum of -402.

We can construct an equation:

[tex](x)+(x+1)+(x+2)=-402[/tex]

Combine like terms:

[tex]x+x+1+x+2=-402\\x+x+x+1+2=-402\\3x+3=-402\\3x=-405\\x=-135[/tex]

Therefore the first integer is -135.

The next two consecutive integers after -135 is -134 and -133.

Therefore, the three consecutive integers are -135, -134 and -133.

Answer:

[tex]\frac{17}{25}[/tex]

Step-by-step explanation:

So because it is a repeating decimal we have to round it off first. We can round it to the nearest hundredth making it 0.68. This then becomes [tex]\frac{68}{100}[/tex] as a fraction which can be reduced to its lowest terms by dividing both the numerator and denominator by 4 and then it becomes [tex]\frac{17}{25}[/tex].

Answer:

280/8 = 35 "sets"

35*3 = 105 Constance

35*5 = 175 vowels

Step-by-step explanation:

There are 105 consonants and 175 vowels in a paragraph.

Vowels (such as a, e, I o, and u) and consonants combine to form words (the rest of the alphabet). The letter "y" is a little odd since it can function as a vowel or a consonant depending on the context. Spelling will be made easier for you if you understand how vowels and consonants combine to form words and sounds.

a speaking sound made by people when their teeth, tongue, or lips obstruct the breath from leaving their mouths. grammar. Except for the English vowels a, e, I o, and u, a consonant is a letter that represents a sound made in this way.

Given:
The ratio of vowels to Constance to a paragraph is 3:5 there are 280 letters in the paragraph.

First to find the number of sets in the paragraph as

[tex]\frac{280}{3+5} = \frac{280}{8} = 35[/tex]

Therefore, there are 35 sets in the paragraph.

So, 35 x 3 = 105 are consonants and

      35 x 5 = 175 are vowels.

Answer:

d) 1/5

Step-by-step explanation:

5(x + 1) - 8 = 5x(2-4)

5x+5-8 = 5x(-2)

5x-3=-10x

15x = 3

x = 1/5

Answer:

Step-by-step explanation:

5(x + 1) - 8 = 5x(2-4)

=> 5x + 5 - 8 = 10x - 20x

=> 5x + 20x - 10x = 8 - 5

Hi there!

We've given with the base area and height. We know the formula for base area

Base area = πr²

154 = 22/7 × r²

154 × 7/22 = r²

49 = r²

√49 = r

7 = r

Now

TSA = 2πr(h + r)

TSA = 2 × 22/7 × 7(7 + 20)

TSA = 44(27)

TSA = 1188 cm²

Answer:

175 miles

Step-by-step explanation:

Hillary has travelled

320 + 350 = 670 miles

in the first two weeks.

Therefore, Hillary starts with 670 miles and needs to add a certain number of miles "x" to get 845 in total.

670 + x = 845

And if we subtract 670 from both sides:

x = 845 - 670 = 175

175 miles

2x - 3(x + 5) = -10

2x - 3x - 15 = -10

2x - 3x = -10 + 15

-x = 5 / : (-1)

x = -5 ← the end
