Simplify number 64. I am a little confused.

Answers

Because 9 has a whole number square root, simplify that first to get 3/root 5.
We don't want roots in the denominator so multiply the fraction by root 5/root 5 which is equal to 1.

Solve 6x2 = 12x − 20.

Answers

If you are using the first X as a multiplication sign and the second as a variable the answer is 8/3 but if both are meant to be variables and the 2 is an exponent the answer is No real solutions
6x^2=12x-20  subtract 12x from both sides

6x^2-12x=-20  divide both sides by 6

x^2-2x=-10/3 halve the linear coefficient, square it, and add it to both sides, in this case 1

x^2-2x+1=3/3-10/3   now the left sides is a perfect square

(x-1)^2=-7/3  take the square root of both sides

x-1=±i√(7/3)  add 1 to both sides

x=1±i√(7/3)

*note that these are imaginary solutions, as the original equation is never true, or if you prefer, 6x^2-12x+20 is never equal to zero.


Which expression is equivalent to 56 + 21?
PLZ NEED HELP

Answers

Option number 4/D. If you distribute:
8 • 7 = 56. And 7 • 3 is 21.
Hope this helps :)
Hello there!

Our question is:
"Which expression is equivalent to 56 + 21?
A.) 7(49 + 14)
B.) 8(7 + 21)
C.) 8(48 + 13)
D.) 7(8 + 3)"

It appears our question wants us to answer our question with two-step expressions by applying the Distributive Property. 
The Distributive Property allows any number/variable outside a parenthesis (with no order of operation symbol between the number/variable and the parenthesis) to multiply by all numbers/variables inside the parenthesis.

For example, this is how to properly apply the Distributive Property;
2(1 + 3)
2(1) + 2(3)
2 + 6

This is NOT how to properly apply the Distributive Property;
2(1 + 3)
2 + 4

Now that we've covered the basics of what we're dealing with, let's try to solve our question using the Distributive Property on our answer choices.

A.) 7(49 + 14);
7(49) + 7(14)
343 + 98.

343 + 98 [tex] \neq [/tex] 56 + 21

B.) 8(7 + 21);
8(7) + 8(21)
56 + 126.

56 + 126 [tex] \neq [/tex] 56 + 21

C.) 8(48 + 13)
8(48) + 8(13)
384 + 104

384 + 104 [tex] \neq [/tex] 56 + 21

Now, all we are left with is D, likely making it our only correct answer, but let's test it out anyways.

D.) 7(8 + 3);
7(8) + 7(3)
56 + 21

56 + 21 = 56 + 21

Your correct answer is D.) 7(8 + 3).

I hope this helps!

The given series has six terms. What is the sum of the terms of the series? 1 + 3 + 5 + . . . + 11

Answers

The rule is +2, so first we find the other two terms.

5 + _ + _ + 11

To find them, add 2 to 5, which gives us 7, so the 4th term is 7, and then add 7 +2, which gives 9, so 9 is the 5th.

Now add all: 1 + 3 + 5 + 7 + 9 + 11 = 36

Your answer is 36.

Answer:  The required sum of the terms is 36.

Step-by-step explanation:  We are given that the following series has six terms :

1  +  3  +  5  +  . . .  +  11.

We are to find the sum of the terms of the series.

We see the following pattern in the consecutive terms of the series :

[tex]3-1=5-3= ~~.~~.~~.~~=2.[/tex]

So, the given series is an ARITHMETIC series with fist term 1 and common difference 2.

We know that

the sum of first n terms of an arithmetic series with first term a and common difference d is given by

[tex]S_n=\dfrac{n}{2}(2a+(n-1)d).[/tex]

For the given series,

first term, a = 1   and   common difference, d = 2.  

Therefore, the sum of first six terms will be

[tex]S_6=\dfrac{6}{2}(2\times 1+(6-1)\times2)=3(2+5\times2)=3(2+10)=3\times12=36.[/tex]

Thus, the required sum of the terms is 36.

Give an example of a polynomial where the ends are both facing downwards.

Answers

A polynomial where the ends are facing downwards is an even-degree polynomial with a negative leading coefficient.

An example for this is : f(x) = -x^2
where the degree is even (2) and the leading coefficient is negative (-1).
When graphing this function, you'll find both ends pointing downwards.

There are some chickens and goats on a farm. Given that the animals have a total of 50 heads and 140 legs, how many more more chicken than goats are there ?

Answers

Let the number of goats be 'x'.
Therefore, the number of chicken will be 50-x 
Total number of legs the goats will have= 4x (goats have 4 legs)
Total number of legs chickens will have= 2(50-x) (chickens have two legs).
4x + 2(50-x)=140
4x+100-2x=140
2x+100=140
2x=40
x=20.
There are 20 goats and 30 chickens.

Brad wants to buy flowers for his friend with $15. The daisies are $1 each and the roses are $3 each. He buys 3 more daisies than roses how much did the roses cost?

Answers

d + 3r = 15
d = r + 3

r + 3 + 3r = 15
4r + 3 = 15
4r = 15 - 3
4r = 12
r = 12/4
r = 3 ....he bought 3 roses, at $ 3 per rose = $ 9 <==

d = r + 3
d = 3 + 3
d = 6....he bought 6 daisies, at $ 1 per daisy = $ 6
Brad wants to buy flowers for his friend with $15. The daisies are $1 each and the roses are $3 each. He buys 3 more daisies than roses how much did the roses cost?
-daisies=x-      -roses=y-

x+y=15

the sentence how he buys 3 more daisies than roses so...
(y=x-3)
you then plug in the value of y in the equation to have only one variable...
x+ 3(x-3)=15
you then multiply 3 to the parenthesis...
x+3x-9=15
then add 9 on both sides...
4x=24
and then divide 4 on both sides...
x=6

if you plug the value of x(daisies) in the equation...
6+y=15
you subtract 6 on both sides and get...
y=9

you can also get the answer by solving for y with x...
y=3(x-3)
(x=6)
plug in x...
y=3(6-3)
y=3(3)
y=9
Answer: the roses cost $9

Find all residues (A) such that (A) is its own inverse modulo 317.

Simpler version: Find all numbers (A) that equal its own inverse modulo 317

Answers

To solve for the value of the residues A, we can use the formula:

A^2 = 1                 (mod prime)

This is only true for prime numbers. The given number which is 317 is a prime number therefore the values of the residues A are:

A = + 1, - 1

Since I believe the problem specifically states for the list of positive integers only and less than 317, a value of A = - 1 is therefore not valid. However, a value of – 1 in this case would simply be equal to:

317 – 1 = 316

 

Therefore the residue values A are 1 and 316.

Marianne buys a house for 150,000 and the value of the house increases at a rate of 1.2% per year.How much will the house be worth in 10 years .Round to the nearest dollar.

Answers

To determine the value of the house in x number of years, we need to derive an equation that would relate the value of the house, the rate of increase and the number of years. If we calculate manually, we would do as follows:

V(1) = 150000 + 150000(0.012)
V(2) = 150000 + (150000 + 150000(0.012))(0.012)
V(3) =  .............

We need to do this up to 10 years. It would be a long and tedious process. We need to simplify the expression as follows:

We factor out the initial amount of the house and simplify further what is inside the parentheses. This would give us
V(x) = 150000 (1 + 0.012)^x 

Substitute 10 to x,
V(x) = 150000 (1 + 0.012)^x10
V(10) = 169003.77

Hello! 

Let's take a look at this problem... okay so it tells us we have six consecutive even numbers...  *** this means that there are six even numbers that come after each other in order ***   ( for example:   2, 4, 6, 8...)   

since we don't know these numbers let's start off by giving them variable values....

x = 1st number
x + 2 = 2nd number     ---->  I added 2 to x cuz the next even number comes     x + 4 = 3rd number               two spots after
x + 6 = 4th number
x + 8 = 5th number
x + 10 = 6th number

now let's form an equation with all this....

(x) + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 270
6x + 30 = 270
6x = 240
x = 40

Now we plug x into the 2nd number's "equation"....

x + 2 
40 + 2
42                   <-----    That's your answer!

Hope this helps! :D

The exact answer to this question is option d that is 18/8 = 2 1/4 and 1 7/12 = 19/12

What is improper fraction and mixed number ?

An improper fraction is a fraction where the numerator is greater than or equal to the denominator. Example 9/4 , 7/2

A mixed number is a number consisting of a whole number and a proper fraction. Example 1 3/8 ,  3 1/3

FOR SOLVING THE QUESTION:

Rewriting 18/8 as a mixed number:

8/8=1 whole

So, let's see how many wholes we can get out of 18/8

18/8= (8+8+2)/8

= 8/8 +8/8 + 2/8

=1+ 1+1/4

18/8=2 1/4

Rewriting 1 7/12 as an improper fraction

1 7/12= 1+ 7/12

=12/12 + 7/12

=(12+7)/12

=19/12

Therefore, 1 7/12= 19/12

The exact answer to this question is option d that is 18/8 = 2 1/4 and 1 7/12 = 19/12

all real numbers..................

Answer:

The correct option is A.

Step-by-step explanation:

The vertex form of an absolute function is

[tex]g(x)=a|x-h|+k[/tex]

Where, (h,k) is vertex.

Domain is the set of input values.

The given function is

[tex]f(x)=3|x+4|+1[/tex]

It is the vertex from of an absolute function. Here h=-4 and k=1, so the vertex of the function is (-4,1).

These functions are defined for all real values of x. So, the domain of the given absolute function is all real numbers

Therefore the correct option is A.
