A jet plane, flying 120 mph faster than a propeller plane, travels 3520 miles in 3 hours less time than the propeller plane takes to fly the same distance. how fast does each plane fly?
Final answer:
The propeller plane flies at a speed of 880 mph, and the jet plane flies at a speed of 1000 mph.
Explanation:
Let the speed of the propeller plane be represented by x mph. Since the jet plane is flying 120 mph faster, its speed can be represented as x + 120 mph.
We know that the distance traveled by both planes is the same, so we can set up the equation:
x * t = (x + 120) * (t - 3)
where t is the time taken by the propeller plane.
Simplifying the equation, we get:
x * t = xt + 120t - 3x - 360
Rearranging the terms, we have:
120t - 3x = 360
Since we have two variables, we need another equation. We can use the formula for distance, which is given by:
Distance = Speed * Time
For the propeller plane, we have:
D = x * t
For the jet plane, we have:
D = (x + 120) * (t - 3)
Since the distance is the same, we can equate these two equations:
x * t = (x + 120) * (t - 3)
x * t = xt + 120t - 3x - 360
Rearranging the terms, we get:
120t - 3x = 360
Solving the system of equations, we find that x = 880 mph and x + 120 = 1000 mph.

A regular hexagon rotates counterclockwise around its center. It turns through angles greater than 0° and less or equal to 360°. At how many different angles of a hexagon map onto itself?
there are 6 sides to a hexagon
360/6 = 60 degrees
so it will map onto itself at 60, 120, 180, 240, 300 & 360
there are 6 different angles

If 1 cm = 0.394 inches, how many inches are in 1 kilometer?
Answer: There are 39400 inches in 1 kilometers.
Step-by-step explanation:
Since we have given that
1 cm = 0.394 inches
As we know that
1 m = 100 cm
1 km = 1000 m
1000 m = 100×1000=100000 cm
1 km = 100000 cm
So, it becomes,
[tex]1\ km=0.394\times 100000\\\\1\ km=39400\ inches[/tex]
Hence, there are 39400 inches in 1 kilometers.
While in europe, if you drive 113 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 41.0 mi/gal ? assume that 1euro=1.26dollars?
Answer:
[tex]\$63.04[/tex]
Step-by-step explanation:
Distance traveled in [tex]1[/tex] day = [tex]113 km[/tex]
Distance traveled in [tex]1[/tex] week = [tex]113*7 = 791 km[/tex]
Mileage of car = [tex]41.0 mi/gal = \frac{41*1.60}{3.78} = 17.35 km/liter[/tex]
Total gas consumed = [tex]\frac{791}{17.35} = 45.49liter[/tex]
Cost of [tex]1liter[/tex] gas = [tex]1.10 euros = 1.10*1.26 = \$1.386[/tex]
Money spent on gas in a week = [tex]45.49*1.386 = \$63.04[/tex]
Brandon is shopping at Old Navy during a sale. All shorts are $16 each and all t-shirts are $10 each.He has $100 to spend and would like to purchase at least 2 pairs of shorts.
a) Write a system of linear inequalities to represent
this situation, then graph.
b)Using your graph, give two possible combinations
of shorts and Brandon can buy.
Two possible solutions are (a) [tex]3[/tex] pairs of shorts and [tex]5[/tex] t-shirts
(b) [tex]4[/tex] pairs of shorts and [tex]3[/tex] t-shirts.
[tex]x=the\; number\; of shorts\\y=the\; number\; of\ t-shirt\; bought[/tex]
So equation formed is
[tex]16x+10y\leq 100[/tex]
[tex]10y\leq 100-16x\\y\leq 10-1.6x[/tex]---Eq [tex]1[/tex]
Bradon wants at least [tex]2[/tex] pair of shorts.Therefore
[tex]x\geq 2[/tex]--Eq [tex]2[/tex]
Now put,
[tex]x=3 \\y=10-1.6(3)\\y=10-4.8\\y=5\\[/tex]
Hence [tex]3[/tex] shorts and [tex]5[/tex] t-shirts
Now put,
[tex]x=4 \\y=10-1.6(4)\\y=10-6.4\\y=3\\[/tex]
Now graph the equation,

What is the common term for the set of all points with x- coordinate zero?
A. X axis
B. Y axis
C. Coordinate plane
D. Origin
Answer:
Option B is the correct answer.
Step-by-step explanation:
We have X axis, Y axis and origin in coordinate plane.
Origin is the point for which both x and y coordinate is zero.
X axis is the set of all points with y- coordinate zero.
Y axis is the set of all points with x- coordinate zero.
Here we are asked to find the common term for the set of all points with x- coordinate zero.
That is Y axis
Option B is the correct answer.

Erin is 8 years younger than twice Paula’s age. The sum of their ages is 40. How old is Erin
To solve this problem, we set up two linear equations based on the given information and solved them simultaneously. We found that Erin's age is 24 years.
Explanation:This problem is a classic example of a linear equation. We can set up two equations based on the information given:
Erin is 8 years younger than twice Paula’s age. This can be written as E = 2P - 8.The sum of their ages is 40. This can be written as E + P = 40.Upon substituting the value of E (Erin's age) from the first equation into the second, we get: 2P - 8 + P = 40. Simplifying this gives P = 16. Substituting P = 16 into the first equation, we find E = 24. Therefore, Erin is 24 years old.
