Answer:

In order to be called a 'rational' number, a number must be the quotient that results when one non-zero integer is divided by another. An irrational number can be written as a decimal, but not as a fraction. Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed.

Answer:

For no. 1:

One of the equations say that y=-7x

So plug in -7x to the other equation as y so you equation would be

-7x= -6x-7

And then, just solve for the variable:

*add -6x to both sides*:

-x= -7

*multiply both by negative one to get a positive variable*

FOR NUMBER 1, THE ANSWER IS:

x=7

Y=-7

For no. 2:

-y=x and your other equation is 3x+5y=20

Plug in x as -y:

-3y+5y=20

*simplify*

2y=20

*divide by 2 on each side to get 1 variable alone*

Y=10

FOR NUMBER 2, THE ANSWER IS:

x=-y

Y=10

Answer:

Step-by-step explanation:

(0 - 2)/(4 - 5)= -2/-1= 2

y - 2 = 2(x - 5)

y - 2 = 2x - 10

y = 2x - 8

Answer:

x=3.33333333

Step-by-step explanation:

Answer:

x = 10/3

Step-by-step explanation:

Divide the coefficient of x (3) on both sides, 3x/3 = 10/3 - then divide the three and the three to get 1 (which stays as x) and then divide ten by three or just leave it as an improper fraction (this all depends on what your teacher's preference) and then you will get the final answer of x = 10/3 or x = 3.3.

Answer:

Step-by-step explanation:

because its squared 5 but 5 regular is almost 4 if u look at bottom theres 4 so x is 5

Answer:

6370 is the answer Hope this helps.

Answer:

6.37 x 10^3 in standard form is: 6370x

Step-by-step explanation:

step 1. let's call the amount of money A, the initial amount A¡, the rate r, and the time t.

step 2. A = A¡e^(rt) (continuously compounding equation)

step 3. A = 125000e^((.0475)(15))

step 4. A = $254,885.32

The value of the account after 15 years will be $254885.

In theory, continuously compounded interest means that an account balance is constantly earning interest and reinvesting that interest so that it, too, earns interest.p explanation.

In finance and economics, interest is the payment of an amount above the repayment of the principal sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or depositor.

Given that you invest $125,000 in an account that earns 4.75% annually for 15 years of the time.

The compound interest will be calculated as:-

[tex]P(t) = P_o\times e^{rt}\\P(t) = 1250000\times e^{0.0475\times 15}[/tex]

P(t) = $254885

Hence, the value of the account after 15 years will be $254885.

Step-by-step explanation:

10 quarters= $2.5 which is 25 dimes

10 nickels= $0.5 which is 5 dimes

10 dimes= $100

100+25+5= 130 dimes = $13

Answer:

a. x=-7 b. -8 hope this helps with the rest of them.

Step-by-step explanation:

a you -28 divided by 4 to simplify x

b. this is a little harder because 6 is a double negative. when it has 2 minus signs that makes it a positive. we have to put 6 on the other side of the equal sign. so we have to minus 6 to put it on the other side. This is because on the left its positive so to put it on the right it has to be a negative. -6 plus -2 = -8. so x is = to -8

14 is the answer

Step-by-step explanation:

Given : the difference between 8 forty-sevens and 7 forty-seven.

To find : Solve it.

Solution : We have given a statement

Difference between 8 forty-sevens and 7 forty-seven.

8 forty-sevens mean 847

7 forty-seven mean 747

Difference between them is

847 - 747 = 100.

Therefore,100.

Farmer need 750.5 feet fencing for his triangular field.

"Triangle is  two dimensional geometrical shape with three sides and three vertices. Sum of all the angles of a triangle is equals to 180°.

Formula used

Cosine rule

As per the diagram,

cosθ = (b² +c² -a²) / 2bc

cos 70° = 0.3420

According to the question,

Let AB = c , AC = b  are given sides of measure 120 feet and 325 feet respectively.

and BC = a

Angle between given sides be θ = 70°

Substitute the value in the formula we get,

cos70° = [ (325)² +(120)² - a²] / 2(120)(325)

⇒ 0.3420 = [ 120025 - a²] / 78000

⇒ 120025 -a² = 26676

⇒ a² = 93349

⇒ a = 305.5

Total fencing required for  triangular field = AB + BC +CA

                                                                      = 120 + 325 + 305.5

                                                                      = 750.5 feet

Hence, farmer need 750.5 feet fencing for his triangular field.

First what I did was take out the 5 dollars. So I did 25 minus 5.

25 - 5 = 20

Next, I divide the left over 20 dollars by 1.25 to see how many tokens Marco could buy.

20 / 1.25 = 16

Which i came up with 16. So Marco can buy 16 tokens and still have enough money to use to buy lunch.
