Answer:
It will take the police car 3.5 hours to travel a distance of 175 miles traveling at a rate of 50 miles/hour.
Step-by-step explanation:
If a car is traveling at a constant speed of 50 miles/hour and we wish to know how long it will take it to travel a distance of 175 miles, we will use this formula
d = r*t
Where d is the distance traveled in miles
r is the rate of speed in miles/ hour, and
t is the time in hours
d in this case is 175 miles and r is 50 miles/hour, plugging this in, we have
175 miles = (50 miles/hour) * t Divide both sides by 50 miles/hour
Our miles unit will cancel out, leaving us with
3.5 hours = t
Answer:
13.4
Step-by-step explanation:
1/3 * 3x + 5.2y

Answer:
(A) 15 centimeters
Step-by-step explanation:
A midsegment of a triangle is always 2 things:
Half the size of the bottom of the triangle (in this case AC)
Parallel to the bottom of the triangle.
Since ABC is an equilateral triangle, we know that EVERY side is 30cm, including AC.
So the midsegment of ABC, LM, must be 15 cm.
Hope this helped!
Answer: 4
Step-by-step explanation:
Set them equal to each other since they're both equal to y
3x-5=.5x +5
add 5 to both sides
3x=.5x+10
subtract .5x from both sides
2.5x=10
divide both sides by 2.5
x= 4
Answer: The first machine would cost $420
and the second machine would cost $432
you should buy the first machine
Step-by-step explanation:If you get a 30% discount, then you are paying 70% of the selling price.
Machine 1: 600(.70) = 420
Machine 2: A 10% discount means you pay 90%
600(.90) = 540 But now you get a 20% discount on that amount, which means you would pay 80%
So, 540(.80) = 432
