Eleven digits for toll calls became standard in all of North America by the end of 1994 to allow introduction of "interchangeable NPA codes" – area codes that did not have a 0 or 1 as the middle digit and could therefore be confused with the central office code – after January 1, 1995.

There are 28 red pens and 84 black pens in a bag.
Write down the ratio of the number of red pens to the number of black pens.
Give your ratio in its simplest form.
Answer:
1/3
Step-by-step explanation:
The ratio can be written as a fraction. This would be 28/84. You simplify ratios just like how you simplify a fraction. 28x3 is actually 84, so the answer in simplest form is 1/3.
Hope this helps and have a great day!! []~(^▽^)~*
The ratio of the number of red pens to the number of black pens in simplest form is, 1 : 3.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
There are 28 red pens and 84 black pens in a bag.
Here, Number of red pens = 28
And, Number of black pens = 84
Hence, The ratio of the number of red pens to the number of black pens is,
⇒ Number of red pens : Number of black pens
⇒ 28 : 84
⇒ 28/84
⇒ 14 / 42
⇒ 1 / 3
⇒ 1 : 3

Simba Travel Agency arranges trips for climbing Mount Kilimanjaro. For each trip, they charge an initial fee of $100 in addition to a constant fee for each vertical meter climbed. For instance, the total fee for climbing to the Shira Volcanic Cone, which is 3000 meters above the base of the mountain, is $400
Let y represent the total fee (in dollars) of a trip where they climbed xxx vertical meters.
Complete the equation for the relationship between the total fee and vertical distance.
Answer:
Step-by-step explanation:
The formula is F(d) = 100+0.10d.
We must find the cost per meter to write the function. We know that the cost to climb a 3000 meter mountain was 400:
400=100+3000(x)
Subtract 100 from each side:
400-100 = 100+3000x-100
300 = 3000x
Divide both sides by 3000:
300/3000 = 3000x/3000
0.10 = x
This is the cost per meter. Using this, we have the formula
F(d) = 100+0.10(d)
Answer:
T(x) = 0.1x + 100Step-by-step explanation:
Total fee is $400Initial one off fee is $100Fee for each meter = xConsidering all the given and the vertical distance of 3000 m we get below equation
400 = 100 + 3000xSolving, we find the fee for each meter:
400 -100 = 3000x300 = 3000xx = 300/3000x = 0.1 dollar per meterSo the equation for total fee including climbing x meters is:
T(x) = 0.1x + 100Find the slope of the line

On a blueprint, an architect drew a 12 inch line to represent the length of a 30-foot room. If the line that represents the width of the room is 8 inches long, how wide is the actual room?
Answer:
20 ft
Step-by-step explanation:
30 ft/ 12 inches= 2.5ft/in x 8 in= 20 ft
I hope this helps and good luck!
The line which represents the width of the room equal to 8 inches long on a blueprint, by the architect, has the size of the room 20 foot.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
On a blueprint, an architect drew a 12-inch line to represent the length of a 30-foot room. Thus, the scale factor of foot to inch is,
[tex]k=\dfrac{30}{12}[/tex]
Let suppose the line that represents the width of the room is 8 inches long, has the size of room in foot is x. Thus,
[tex]k=\dfrac{8}{x}\\\dfrac{12}{30}=\dfrac{8}{x}\\x=\dfrac{30\times8}{12}\\x=20[/tex]
Thus, the line which represents the width of the room equal to 8 inches long on a blueprint, by the architect, has the size of the room 20 foot.

What is Pythagoras theorem?The Pythagoras theorem states that if a triangle is right-angled, then the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Formula of Pythagoras theorem
Hypotenuse² = Perpendicular² + Base²
According to the question
A plane flies 35 km in the direction N 30° W,
and then flies 60 km in the direction N 60° E
i.e
When we plot its figure
we will observe it will form a right angled triangle
with perpendicular = 35 km , Base = 60 km
and Hypotenuse = distance form original location to current location
Now,
By using the formula of Pythagoras theorem
Hypotenuse² = Perpendicular² + Base²
Hypotenuse² = 35² + 60²
Hypotenuse² = 4825
Hypotenuse = 69.46 km
Hence, the distance of the plane from its original location is 69.46 km.

In arithmetic, variables look like letters.
Step-by-step explanation:
As we know that Mathematical arithmetic deals with numbers and certain properties with them.
Some of the main properties between numbers are as follows:
AdditionSubtractionMultiplicationDivisionVariables do not remain constant, so we basically assign a number to a variable with an equal operator denoted by '='.
For example, let us assume a variable x being equal to 7. so it can written as:

Let suppose the value of the variable x=7 changes to x=10, then the new value will be:

Step 1: To find the gallons of gas needed to make 1mile
The car uses 15 gallons of gas to make 200 miles.
from this we get,
gallons of gas needed to make 1mile = 15/200 =3/40
Step 2: To find the gallons of gas needed to make 320 miles
Therefore, the gallons of gas needed to make 320 miles = 320 x(3/40) = 24 gallons of gas
