The speed of the plane is 420 miles per hour and the speed of the wind is 10 miles per hour.
Answer:
I only know English, so that's perfect :P
Step-by-step explanation:
I'm going to guess... that "Herman" is really "headwind" and that this jet is flying into ( headwind) and with ( tailwind) the same wind... so the same velocity wind ( note I used the physics term velocity for the speed of the wind b/c the wind also has to have a direction... and we are saying it's direction and it's speed are constant)
so take the difference of the two distances... 1290 - 1230 = 60
we now know... that the difference in distance traveled is 60 miles, so 1/2 of that is what's gained or lost , by a tailwind or a headwind, so 30 miles is gained or last flying into the wind or with the wind.
also this is in 3 hours , how convenient, 30 / 3 = 10
the wind is 10 MPH
there fore.... the jet could fly 1260 miles in 3 hours with out any wind or
d = rt where d= distance , r= rate ( think speed) and t = time ( of course [ofc] )
1260 = r * 3 hours
420 = r
the jets speed is 420 MPH

Eric's employer pays him a monthly salary of $1400, plus a commission of $75 for
every fish tank that he sells. Nancy's employer does not pay her a salary. Instead, they
offer her a commission of $250 for every fish tank that she sells.
How many fish tanks would they each need to sell so that they bring in exactly the
same amount of money per month?
Answer:
8
Step-by-step explanation:
Eric's salary: y=75x+1400
Nancy's salary: y=250x.

What is the greatest common factor of 18 and 50
Answer:2
Step-by-step explanation:
18 divided by 2 equals 9
and for 50 it’s 15 because 50 divided by 2 is 15 so it’s 2
The greatest common factor of 18 and 50 is 2.
What is the Greatest Common Factor (GCF)?Greatest Common Factor is defined as the greatest number that is a factor of both numbers when two numbers are involved.
A number that divides into another number completely is said to be a factor.
To put it another way, any two integers that multiply to produce a result are factors of the result.
We have to determine the greatest common factor of 18 and 50
The prime factorization of 18 is
⇒ 2 x 3 x 3 = 18.
The prime factorization of 50 is
⇒ 2 x 5 x 5 = 50.
The occurrence of common prime factors of 18 and 50 is 2.
So the greatest common factor of 18 and 27 = 2.
Therefore, the greatest common factor of 18 and 50 is 2.

The admission fee at an amusement park is 1.5 dollars for children and 4 dollars for adults. On a certain
day 369 people entered the park, and the admission fees collected totaled 1016 dollars. How many
children and how many adults were admitted?
Answer:
184 children and 185 adults!
Step-by-step explanation:
So let's suppose there are x children who entered the park that day, then there will be (369-x) adults who entered the park that day.
So we have an equation!
1.5x+4(369-x)=1016
1.5x+1476-4x=1016
Then we swivel things around a bit.
1476-1016=4x-1.5x
2.5x=460
x=184
There are 184 children in that park that day! Wow, that's a lot of people, next we calculate the number of adults:
369-184
=185
OK, 184 children and 185 adults!

If a triangle has side lengths of 12,24 and 8 what is the hypotenuse side?
Answer:
24.
Step-by-step explanation:
The hypotenuse of a triangle is simply the slanted side of a triangle and it is always the longest side of any triangle.
Mathematically, the hypotenuse of a triangle is calculated using the Pythagorean theorem;
C² = A² + B²
Where;
C is the hypotenuse i.e the longest side.
A is the opposite side of the triangle.
B is the adjacent side of the triangle.

Two lines, M and N, are represented by the following equations:
Line M: y = x + 3
Line N: y = −2x + 6
Which of the following options shows the solution to the system of equations and explains why?
(1, 4), because the point does not lie on any axis
(1, 4), because one of the lines passes through this point
(1, 4), because both lines pass through this point
(1, 4), because the point lies between the two axes
Answer:
Third answer shown
Step-by-step explanation:
Since each equation has a right side equal to the same thing, y, those right sides must be equal to each other.
x + 3 = -2x + 6
Add 2x to both sides. 2x 2x
3x + 3 = 0 + 6
3x + 3 = 6
Subtract 3 on both sides. -3 -3
3x = 3
Divide both sides by 3. x = 1
Now, let's see what y must be if x equals 1.
Line M: y = x + 3 --> y = 1 + 3 --> y = 4
Line N: y = -2x +6 --> y = -2(1) +6 --> y = -2 + 6 --> y = 4, confirmed
So the ordered pair (x, y) that satisfies both equations is (1, 4)
*** This means that if you graphed both lines on an xy-coordinate plane, the point (1,4) would be the point where the two lines intersect.
That is the third answer shown.

In 2010 an item costs $9.00. The price increases by 1.5% each year. How much will it be in 2030?
Answer:11.7
Step-by-step explanation:
1. Recognize variables. Starting price is 9, it’s increasing by 1.5% each year, the question asks for the price in 20 years.
2. Convert percentage to decimal. Most calculators won’t understand multiplying by percentages, and instead will understand multiplying by decimals. A decimal is something we can easily work with. It is more commonly taught to work with decimals as well. With that said 1.5% equals .015. (The number in the ones place in the percentage is always in the hundredths place when converted to a decimal, the tens to the tenths, the hundreds in the percentage to the ones place in the decimal, the hundredths in the percentage to the ten thousandths in the decimal. Basically, every individual number [the 5 in 1.5] moves two spaces to the right when going from percentage to decimal form, likewise two to the left going from decimal to percentage form. 23%=.23, 104%=1.04, 0.5%=.05, 1.234%=.01234)
3. Make your equation
20(9*(.015))+9
+9 is your starting point
9*(.015) gives you the amount the price increases per year
20 is multiplied then to that increased price for the next 20 years
4. Crunch em numbers
PEMDAS
The cost of the item in 2030 is $10.449.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation
We have,
Cost of an item = $9
The item increases per year = 1.5%
Now,
The equation for the cost of the item after x years.
= 9[tex](100 + 1.5)^x[/tex]
Now,
There are 10 years from 2010 to 2030.
So,
x = 10
= 9 [tex](1 + 0.015)^{10}[/tex]
= 9 x [tex]1.015^{10}[/tex]
= 9 x 1.161
= 10.449
Thus,
The item will cost $10.449 in 2030.
