Answer:

$0.70 per letter, $1.50 flat fee

Step-by-step explanation:

x+18y=14.1 -> x=-18y+14.1

x+35y=26

|

\/

(-18y+14.1)+35y=26 -> 17y=11.9 -> y=0.7

|

\/

x+35(0.7)=26 -> x+24.5=26 -> x=1.5

|

\/

y=0.7

x=1.5

Hope this helps. :)

The post office charges $0.70 to send one letter, and there is a flat fee of $1.50.

To find the cost of sending one letter, we need to determine the flat fee charged by the post office.

Let's denote the flat fee as 'F' and the cost per letter as 'C'.

From the given information, we can set up the following equations:

Equation 1: F + 35C = 26

Equation 2: F + 18C = 14.10

We can solve this system of equations to find the values of F and C.

First, we subtract Equation 2 from Equation 1 to eliminate F:

(F + 35C) - (F + 18C) = 26 - 14.10

17C = 11.90

Now, we divide both sides of the equation by 17 to solve for C:

C = 11.90 / 17

C ≈ 0.70

Therefore, the cost to send one letter (C) is approximately $0.70.

To find the flat fee (F), we can substitute the value of C into either Equation 1 or Equation 2. Let's use Equation 1:

F + 35(0.70) = 26

F + 24.50 = 26

F = 26 - 24.50

F = 1.50

Therefore, the flat fee (F) charged by the post office is $1.50.

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Answer: g>12(the first one)

Step-by-step explanation:

The reason it is g>12 because It said Sean has already written 12 and he needs to write more. So g has to be greater than 12. You would graph it like you would click on 12, and click on 12 again to make it a open circle and then you would press the arrow on the right.

Step-by-step explanation:

factoring , using square roots , completing the square and the quadratic formular

Answer:

See below.

Step-by-step explanation:

The four main ways to solve a quadratic equation are:

1) Factoring, 2) Completing the Square, 3) Graphing, and 4) Quadratic Formula.

Each method has it's own pros and cons.

1) Factoring. You should factor when the given equation is easily factor-able or already factored. For instance:

\(0=x^2-4x-12\\0=(x+7)(x-1)\)

These problems are easily factored so factoring is preferred here. However, factoring will not always work.

2) Completing the Square. You complete the square if you are able to complete the perfect square trinomial with only integers. For instance:

\(x^2-2x-7=0\\(x^2-2x+1)-7-1=0\\(x-2)^2-8=0\)

However, you wound't use completing the square if:

\(x^2-3x+2=0\\(x^2-3x+9/4)+2-9/4=0\)

The perfect square trinomial includes fractions so you would use alternative methods here (and factoring works here!).

Despite the complexity of completing the square, if done correctly, it works every time. However, sometimes, it can be time-consuming.

3) Graphing. Graphing (if on paper) is time-consuming. You would only use graphing when you only need an approximation. Unless directed to, you probably won't need to use graphing.

However, if you have a graphing calculator, graphing the equation can allow you to check your answer. So, graphing won't get you precise answer, but it will allow you to check your answer is necessary.

4) Quadratic Formula. Use the quadratic formula if the equation isn't factor-able and completing the square is too tedious. For instance:

\(4.1x^2-3x-7=0\\\)

This doesn't seem factor-able and completing the square will take a while. Graphing won't get the exact answer, so the quadratic formula is the only avenue left.

The quadratic method, like completing the square, will always work.

Only con is that you need to memorize the formula.

Answer:

14.5 degrees

Step-by-step explanation:

The total amount of degrees in a triangle is 180

67.5+55=122.5 degrees

That means that there would be 57.5 (180-122.5) degrees left for the measure of angle 3x+14.

3x+14=57.5

-14     -14

3x=43.5

x=14.5

Answer:

Since this is an equilateral triangle, the two angles at he bottom are equal. 55-14= 41, and 41/3= 13 2/3, so x=13.6 repeating.

Step-by-step explanation:

1. The hidden question is "What was the high temperature four days earlier?"

2. To find the high temperature four days earlier, we need to subtract 14.2 from the record high temperature of 39°C:

39 - 14.2 = 24.8°C

3. The main question is "How much higher was the record temperature than the high temperature four days earlier?"

4. To find the difference between the record temperature and the high temperature four days earlier, we need to subtract 24.8 from 39:

39 - 24.8 = 14.2°C

So, the record temperature was 14.2°C higher than the high temperature four days earlier.

Answer:

(x, y) = (4, 11).

Step-by-step explanation:

We have two equations:

3(y-2x) = 9

x - 4 = 0

From equation 2, we have x = 4. We can substitute this value into equation 1 and solve for y:

3(y-2x) = 9

3(y-2(4)) = 9 (substitute x = 4)

3(y-8) = 9

3y - 24 = 9

3y = 33

y = 11

Therefore, the solution to the system of equations is (x, y) = (4, 11).

He forgot to flip the second fraction.

Step-by-step explanation:

He has:

−8/9 ÷ 9/8 = −8/9 × 9/8 = −72/72 = −1

He made a mistake. When you change a division to a multiplication, you must use the reciprocal of the second fraction. You have to flipt the second fraction. He did not flip it.

This is correct:

−8/9 ÷ 9/8 = −8/9 × 8/9 = −64/81

Answer:

Hello

Step-by-step explanation:

You can take away the decimals

for example 0.33 x 0.7

do 33 x 7

which is 231

the 0.33 has 2 decimal spaces because there are 2 digits after the point

0.7  has 1 decimal place because there is 1 digit after the point.

so in total, there is 3 decimal

because you do 2 + 1

3

from the left, you count backwards and add the decimal point

the final answer should be 0.231

   3/4 % of 801 would be this answer divided by 100 .... = 6

Answer:

The point-slope form of the equation of a line is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. In this case, we have a point (-1,-2) and a slope of 3. Substituting these values into the equation, we get:

y - (-2) = 3(x - (-1))

Simplifying this equation, we get:

y + 2 = 3(x + 1)

So, the equation for the linear function whose graph contains the point (-1,-2) and has a slope of 3 is y + 2 = 3(x + 1).

Answer:

845 miles

Step-by-step explanation:

First let us find the speed ( rate ) using the below formula.

\(\sf Speed=\frac{Distance \:\:travellled}{Time\:\:Taken}\)

\(\sf Speed=\frac{585 \:miles}{9 \:h}\)

\(\sf Speed=65\:miles\: per\: hour\)

They also said that, at the same speed he traveled for 13 hours.

So, now we have to find the distance.

For that, you can use the same formula by making the distance as the subject.

Let us find it now.

\(\sf Distance \:\:travellled=Speed\:*\:Time\:\:Taken\\\\\sf Distance \:\:travellled=65\:*\:13\\\\\sf Distance \:\:travellled=845 \:miles\)

Answer: Your welcome!

Step-by-step explanation:

The answer is 1/36. To solve this, the first step is to simplify the expression by using the power rule for multiplication: (4^0 * 3^2)^-2 = (3^2)^-2. The next step is to use the power rule for division: (3^2)^-2 = 3^(-2 * 2) = 3^-4. Finally, we can use the power rule for negative powers: 3^-4 = 1/3^4 = 1/81 = 1/36.
