Suppose two automobiles leave from the same point at the same time. If one travels north at 60 miles per hour and the other travels east at 45 miles per hour, how fast will the distance between them be changing after three hours?
Answer:
225milesStep-by-step explanation:
velocity is the change in displacement with respect to time
Speed Δv = Δd/t
Δd = tΔv
Δv is the change in speed
t is the time taken 3 hours
Substitute the given parameters into the formula;
Using the pythagoras theorem to get the change in velocity
v² = 60²+45²
v² = 3600+2025
v² = 5625
v = √5625
v = 75miles/hour
Substitute the gotten values inti the formula;
Δd = tΔv
Δd = 3*(75)
Δd = 225miles
The distance between them be changing by 225miles after 3 hours

A rectangle and square have the same area.
The rectangle has length 12x and width 3x.
Find the length of each side of the square.
(20 points)
Answer:
12x*3x=36x^2
squarelength=[tex]\sqrt{36x^2}[/tex]=6x
Step-by-step explanation:
Length of each side of a square is equals to 6x.
What is rectangle?
" A rectangle is a two dimensional shape whose opposite sides are parallel and congruent to each other. Each of the interior angle is of measure 90°."
What is square?" A square is a parallelogram whose all sides are congruent to each other. Each of the interior angle is of measure 90°."
Formula used
Area of rectangle = length × width
Area of square = (side)²
According to the question,
length of a rectangle = 12x
width of a rectangle = 3x
Substitute the value in the formula we have,
Area of rectangle = 12x × 6x
= 36x²
As per the question,
Area of rectangle = Area of square
Therefore ,
Area of square = 36x²
⇒ (side)² = 36x²
⇒ side = 6x
Hence, length of each side of a square is equals to 6x.

Aisha took the train spoklane to seattle. the distance is 250 miles and the trip took 3.5 hours. wha was the speed of the train
Answer:
I believe the answer is 72.88 Miles Per Hour (MPH).
Step-by-step explanation:
If the distance being traveled is 250 miles and the time it took was 3.5 hours, then you should divide the 250 miles by the 3.5 hours it took to get there. By dividing 250 by 3.5, you can get 72.88, which should be the answer.

The revenue in dollars of a company that produces video game systems can be modeled by the expression 5X squared 2+ 2X -80 the cost in dollars of producing video game system can be modeled by 5X squared two minus X +100 where X is the number of video game sold if profit is the difference between revenue and cost what expression represents the prophet
Answer:
required expression for profit = 3x - 180
the profit by selling 1000 units will be $ 2820
Step-by-step explanation:
Given,
Revenue = 5x² + 2x -80
cost = 5x² - x + 100
Hence profit = Revenue - cost
=> profit = 5x² + 2x -80 - (5x² - x + 100)
=> profit = 5x² + 2x -80 - 5x² + x - 100
=> profit = 3x - 180
which is the required expression for profit.
number of video games sold = 1000
=> x = 1000
hence,
profit = 3x - 180
= 3000 - 180
= $ 2820
hence the profit by selling 1000 units will be $ 2820

Answer:
[tex]x=5^o[/tex]
[tex]m\angle EBD=50^o[/tex]
Step-by-step explanation:
First case: angleEBD = 86 degrees, and angleDBC = 7 x + 8
Since BD bisects angleEBC, then angleDBC = 86/2 degrees = 43 degrees
then 43 = 7 x + 8
solving for "x":
43 - 8 = 7 x
35 = 7 x
dividing both sides by 7:
x = 5 degrees
Second case: angleEBD = 5 x + 20 and angleDBC = 7 x + 8
Since both angles must be of the same measure because BC is the bisector, then we can write the equation:
5 x + 20 = 7 x + 8
solve for x:
20 = 7 x - 5 x + 8
20 - 8 = 2 x
12 = 2 x
x = 6 degrees
now use x = 6 degrees to find angle EBD:
angleEBD = 5 (6) + 20 = 30 + 20 = 50 degrees.

Do i do it like -4x-4 and so on or just 4x4. And so on
Answer:
as cheecks
Step-by-step explanation:
Answer:
you should multiply 4 by -5, 5 times, so 4 times -5 = -20 then multiply by -5 = 100 then multiply y -5 = -500 then multiply by -5 = 2,500 then multiply by -5 equals = -12,500
or just 4 times -5 = -20 because I don't know how they teach you.
So if you will expand it it will be eaither-12,500 or -20, it's how they teach you.
