Answer:
it will take 1.4 hours for the two trains to be 294 miles apart
Step-by-step explanation:
Let t be the time taken for each train
The westbound train travels at 95 miles per hour.
Speed of westbound train = 95
time = t
Distance = speed * time = 95 t
The eastbound train travels at 115 miles per hour
Speed of eastbound train = 115
time = t
Distance = speed * time = 115 t
both trains are 294 miles apart means the distance between both trains are 294 miles
So we add the distance of both trains and set it equal to 294
95t + 115t = 294
210 t =294
t = 1.4
So, it will take 1.4 hours for the two trains to be 294 miles apart
we are given that ,
The combined area of two squares is 17 square meters.
Area of square=
Let the side length of smaller square be x
The size of the larger Square are four times as long as the size of the smaller square
So Area of larger square=
The combined Area is 17 square meter.
Hence the smaller square has the side length=
So the larger square has side length=
Answer:
The y= -28x+4 function is changing more quickly because the -28 of x is the bigger number meaning it is the bigger slope.
Step-by-step explanation:
hopefully that helps, if not let me know of the option you have that I can select from to fully answer the question.
So remember that the pythagorean theorem is a^2+b^2=c^2
c=18
legnth is 3 more than width
l=3+w
a=3+b
subsitute
(3+b)^2+b^2=18^2
expand
9+6b+b^2+b^2=324
subbtract 9 from both sides
6b+2b^2=313
subtract 313 from both sides
2b^2+6b-313=0
factor
use quadratic formula and get
b=11.1
subsitute
a=3+b
a=3+11.1
a=14.1
answer is 14.1 ft by 11.1 ft
