Find 65% of 300 kilometers.

Answer:13

Step-by-step explanation:

The expression that represents the perimeter of the rectangle is: 8/3w + 10 units

Perimeter of rectangle = 2(length + width).

Let the width be represented as variable w

Width = w

Length of the rectangle = 1/3w + 5 units

Thus, substitute the values into the formula

Perimeter of the rectangle = 2(1/3w + 5 + w)

Simplify

Perimeter of the rectangle = 2(4/3w + 5)

Perimeter of the rectangle = 8/3w + 10 units

Therefore, the expression that represents the perimeter of the rectangle is: 8/3w + 10 units

Based on the formulas given for PR and QR, the length of PR is 19.8 units.

The shape that is given is an equilateral triangle. This allows us to know that all the sides of the shape are equal.

This means that PR and QR are the same:

PR = QR

Equate both formulas as:

2n + 9 = 7n - 18

You can then solve for the value of n:

7n - 2n = 18 + 9

5n = 27

n = 5.4

The length of PR can then be solved by using substitution:

= 2n + 9

= 2 (5.4) + 9

= 19.8 units

yes, if the value of the coin is 1 dollar, then it will exceed the million dollars within 28 days.

It will depend on the original value of the coin, value that we don't know, so I will assume that the value of the coin is $1.

If this coin doubles each day, then the day zero its value is $1.

After one day its value is 2*$1 = $2

After another day its value is 2*$2 = $4

And so on, this is modeled by the exponential equation:

y = $1*(2)^x

Where y is the total value and x is the number of days.

After 28 days (this means we use x = 28) the value will be:

y = $1*(2)^28 = $268,435,456

That is a lot more than one million dollars.

So yes, if the value of the coin is 1 dollar, then it will exceed the million dollars within 28 days.

Answer:

x=1 y=3

Step-by-step explanation:

Hello!

So, this says to use the substitution method. The substitution method is where you set one equation equal to one of the letters, and then put that whole equation in the other equation.

So->

3x-y=0

if we move the y to the other side we have:

3x=y

then we have our second equation:

2x+y=5

Now, we don't know what NUMBER y is yet, but we do know that it is equal to 3x. Thus, we can put it into the equation like this.

2x+(3x)=5

Then, we can add like terms and get:

5x=5

Dividing each term by five, we get

x=1

We could have also done this be solving for x in the equations and then substituting that in instead of y.

Now that we have x, we can easily put it into the equations and solve for y.

3x-y=0

3(1)-y=0

3=y

So now we know that x is equal to 1 and y is equal to 3.

Answer:

  A.) P(t) = 130t +3330

  B.) P(16) = 5410

Step-by-step explanation:

Given the ordered pairs (t, P(t)) = (2, 3590) and (9, 4500), you want a linear model that describes the relation. You also want the value of P(16).

We can write the formula for P(t) starting with the point-slope equation for P in terms of t. To do that, we need the slope:

  m = (P2 -P1)/(t2 -t1)

  m = (4500 -3590)/(9 -2) = 910/7 = 130

The point-slope equation will be ...

  P -P1 = m(t -t1)

  P -3590 = 130(t -2)

Solving for P, we find ...

  P = 130t -260 +3590 . . . . . eliminate parentheses, add 3590

  P(t) = 130t +3330

The value of P(16) will be ...

  P(16) = 130(16) +3330 = 2080 +3330 = 5410

The moose population is predicted to be 5410 in 2006.

Additional comment

The value of t is years since 1990, so the relevant values are ...

  1992: t = 1992 -1990 = 2

  1999: t = 1999 -1990 = 9

  2006: t = 2006 -1990 = 16

Values of moose population by  linear model A.) P(t) = 130t +3330  B.) P(16) = 5410

What does the term "linear model" mean?

Given the ordered pairs (t, P(t)) = (2, 3590) and (9, 4500), you want a linear model that describes the relation. You also want the value of P(16).

A.) Linear model

We can write the formula for P(t) starting with the point-slope equation for P in terms of t. To do that, we need the slope:

 m = (P2 -P1)/(t2 -t1)

 m = (4500 -3590)/(9 -2) = 910/7 = 130

The point-slope equation will be

 P -P1 = m(t -t1)

 P -3590 = 130(t -2)

Solving for P, we find

 P = 130t -260 +3590 . . . . . eliminate parentheses, add 3590

 P(t) = 130t +3330

B.) Prediction

The value of P(16) will be

 P(16) = 130(16) +3330 = 2080 +3330 = 5410

The moose population is predicted to be 5410 in 2006.

(B) The value of t is years since 1990, so the relevant values are

 1992: t = 1992 -1990 = 2

the mid point of the points C and D is M = ( 4 , - 1 / 2 ).

We are given the coordinates of the point:

D ( 7 , 5 )

We need to find the mid point M for it.

Here, we have:

x₁ = 1

x₂ = 7

y₁ = - 6

y₂ = 5

We know that the formula for mid point is given by:

M = ( x₁ + x₂ / 2, y₁ + y₂ / 2 )

Substituting the values, we get that:

M = ( 1 + 7 / 2 , - 6 + 5 / 2 )

M = ( 8 / 2 , - 1 / 2 )

Savings account is a basic account type that lets you deposit money safely with a bank. It ensures safety and access to your money whenever you need. You can withdraw your funds, either digitally or in person, at any point in time.

Having a savings account is a liquid investment, so you have the ease of using your funds any time for transactions. A savings account also earns decent returns;

A savings account is like a virtual locker that safeguards your money and pays a certain amount of interest. As opposed to a fixed deposit (FD), you can use the money in your savings account whenever you need. A savings account also has other uses.

With your savings bank account, you make transactions, receive payments, pay your credit bills, and make investments. You can also pay for utilities such as electricity bills, ration, mobile phone recharges, and shopping. A savings account safeguards your money from theft and misplacement and reduces the stress that comes with carrying too much cash.

how to calculate saving

If the daily amount is Rs 3 lakhs and the interest rate on the savings account is 4% per year, the computation will be Interest on a monthly basis = Daily Balance * (Number of days) *Interest / (Days in the year)3 lakhs * 30 * (4/100) / 365 = Rs 986 per month in interest Daily

balance: 3 lakh

Number of days: 30

Interest: 4%

Days in the year: 365
