pls pls help

Answer:

D= -16.8

Step-by-step explanation:

========================================================

Explanation:

Whenever you have a series of nothing but '1's like this, the base 10 equivalent is always going to be 1 less than a power of 2.

The number will be of the form [tex]2^n-1[/tex] where n is a nonnegative integer.

If you're familiar with the list of powers of 2, then you'll likely realize that 64 is a power of 2 since [tex]2^6 = 64[/tex]. One less than this is [tex]2^6-1 = 64-1 = 63[/tex]

This leads to choice A as the answer.

The other answer choices are not one less than a power of 2, so we can cross those off the list.

------------------------------

Further explanation:

Each slot in the binary number given represents a power of 2. We multiply those '1's by a power of 2 and add them up like so

1*(2^5) + 1*(2^4) + 1*(2^3) + 1*(2^2) + 1*(2^1) + 1*(2^0)

1*32 + 1*16 + 1*8 + 1*4 + 1*2 + 1*1

32 + 16 + 8 + 4 + 2 + 1

63

Summing the first n powers of 2 leads to the result [tex]2^{n}-1[/tex]

So, summing the first 6 powers of 2 leads to [tex]2^n-1 = 2^6-1 = 63[/tex]

Answer: 20/22

Step-by-step explanation:

You divide 5/14 by three and then multiply that answer by 8

Answer:

Pretty sure its false

Step-by-step explanation:

Answer: False

Step-by-step explanation:

Answer:

angles 1 and 3 are 30

angles 5, 8, 10 and 12 are all 85

angle 11 is 95

angles 9 and 6 are 30

7 and 4 are 65

Step-by-step explanation:

angle 2 is congruent to 150, so 1 and 3 are: 360 degrees -150-150=x/2 to get the angles, then cos its an isosceles triangle due to the parallel lines, 9 and 6 are congruent to 1 and three, and 11 is 95 so you do 360 degrees-95-95=x/2 to get 85, then you take the 95 that is congruent to the angle group below it, and subtract 30 cos angles 9 and 4 are equivalent to the whole angle of 11, so yea u subtract 30 and you get 65, and you match up the congruent ones lol hope this helps ik its confusing

Answer:

x = 6

Step-by-step explanation:

-(x - 8) = 2

multiply the negative

-x + 8 = 2

subtract 8 from both sides

-x = -6

x = 6

Answer:

x = 6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

-(x - 8) = 2

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 2 does indeed equal 2.

∴ x = 6 is the solution to the equation.

Answer:

Step-by-step explanation:

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Answer:

(-6, 0)

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

The solution set to the systems of equations is where the 2 lines intersect.

According to the graph, the 2 lines intersect at (-6, 0).

Therefore, our x-intercept for both graphs is our solution set to the systems of equations.

Answer:

It is (-6, 0)

Answer:The scale factor is 20.

Step-by-step explanation:

6 INCHES = 1/2 FOOT

10 FOOT TO 1/2  FOOT = 10/(1/2) = 20/1

The scale factor is 20 to 1

or, since your scale is 6 in to 10 ft

you may list the scale factor as 1 to 20

The scale factor is 20 .

To understand more, check below explanation.

Given that,

Size of the room on blue print = 6 inches

Actual size of the room = 10 feet

As we know that,

               1 feet = 12 inches

             6 inches = 1/2 feet

We have to find scale factor from 1/2 feet to 10 feet.

      [tex]\frac{10}{1/2}=\frac{10*2}{1} =20[/tex]

Hence, the scale factor is 20 .

Answer:

12 1/4

Step-by-step explanation:

You would first add the fractions which will get you 5/4. then you will add the whole numbers which will get you 11. Then there is a extra number in 5/4 so you can tranfer it to the whole number which will become... 12 and then you will be left with 12 1/4

Answer:

the correct answer is d

Answer:

4/ 5

is greater than  

25 /40

Step-by-step explanation:

Find the least common denominator or LCM of the two denominators:

LCM of 5 and 40 is 40

For the 1st fraction, since 5 × 8 = 40,

4/ 5  =  4 × 8  5 × 8  =  32/ 40

Likewise, for the 2nd fraction, since 40 × 1 = 40,

25 /40  =  25 × 1  40 × 1  =  25/ 40

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

32 /40  >  25 /40  or  4 /5  >  25 /40

Answer:

It is not true because if you multiply the denominator by 8, you will get 40 and if you also multiply the numerator by 8, you get 32 which is 32/40 which is not equal to 25/40.
