(4*3^22+7*3^21)*57 divided by (19*27^4)^2

Answers

Answer 1
Answer: (4*3²²  + 7*3²¹)*57    ÷        (19*27⁴)²

(4*3²²  + 7*3²¹)*57        Factorize out 3²¹

3²¹(4*3  + 7)* 57

3²¹(12  + 7)* 57

3²¹(19)* 57.      But 57 = 19 *3

3²¹(19)*(19*3)

3²¹ *3*(19)* 19.

= 3²² 19²


Bottom:
(19*27⁴)² = 19² * 27⁴ˣ²

19² * 27⁸ 

19² * (3³)⁸

19² * 3³ˣ⁸

=19² * 3²⁴          

(3²² *19²) ÷ (19² * 3²⁴)    Applying law of indices of multiplication and division

= 3²²⁻²⁴ 19²⁻²

= 3⁻² 19⁰          19⁰ = 1

=  3⁻² * 1.   

=   3⁻² = 1/3²   

= 1/9

What is the missing value from the table

Answers

Answer:12

Step-by-step explanation:In the table you can see that the numbers given under Y

Are in a pattern counting by sixes so if you do 6×3 you get 18 for missing the second one so we do 6×2 which equals 12 and that is the answer.
The answer is going to be 12.

Which expression is equivalent to 3x + 14 + 3x + 10?A. 4 ( x + 6 )

Thank You Very MUCH!!!

Answers

The required expression is equivalent to 6(x + 4). Option D is correct.

What is simplification?

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve. For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property.

Here,
Combine like terms by adding the coefficients of the x-terms and the constants:

3x + 14 + 3x + 10 = 6x + 24

Therefore, the expression is equivalent to 6(x + 4).

So,

3x + 14 + 3x + 10

Let's put the placeholders together to make it simpler.

3x + 3x + 14 + 10

Collect Like Terms
6x + 24

This is simplified.

Option D, when multiplied, gives 6x + 24.  So that is the correct option.

The number of chips of different colors in Gail's bag is shown below:3 blue chips
4 pink chips
8 white chips
Gail takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Gail takes out a white chip in both draws?
A.(8)/(15)+(7)/(14)=(217)/(210)
B.(8)/(15)×(7)/(14)=(56)/(210)
C.(8)/(15)+(8)/(15)=(16)/(15)
D.(8)/(15)×(8)/(15)=(64)/(225)

Answers

Answer:

(8)/(15) * (8)/(15)=(64)/(225)

Step-by-step explanation:

Given : 3 blue chips

            4 pink chips

            8 white chips

To Find:  What is the probability that Gail takes out a white chip in both draws with replacement?

Solution:

Blue chips  =3

Pink chips  =4

White chips =8

Total chips = 3+4+8 =15

Now Probability of getting white chip on first draw = \frac{\text{Number of white chips }}{\text{Total no. of chips}}

                                                                                   = (8)/(15)  

Now ,She replaces the chip and then takes out another chip from the bag.

So, Probability of getting white chip on second draw = (8)/(15)  

Probability of getting white chip in both draws = (8)/(15) * (8)/(15)=(64)/(225)

Hence the probability that Gail takes out a white chip in both draws is (8)/(15) * (8)/(15)=(64)/(225)

Thus Option D is correct.
most likely the probability is D because my mom said it is d i dont know how she got it

slope=rise/run

easy
if we imagine a graph in our head
we see that the graph goes down, negative slope
it goes down 4 units and to right 6, so 4/6=2/3 but it is negative so -2/3

other way is
(y2-y1)/(x2-x1)=(0-4)/(6-0)=-4/6=-2/3
