Answer:
Copy's area is 16 times bigger then triangle area.
Step-by-step explanation:
Given:
Area of copy = 72 unit²
Find:
How bigger copy compared to triangle
Computation:
Area of triangle = [1/2][base][height]
Area of triangle = [1/2][3][3]
Area of triangle = 4.5 unit²
So.
Area of copy / Area of triangle
72 / 4.5
16
So,
Copy's area is 16 times bigger then triangle area.
Answer:
Part 1) 300 miles
Part 2) 420 miles
Part 3) 600 miles
Step-by-step explanation:
we have
where
d(x) is the distance in miles
x is the time in hours
Part 1) How many miles will he have traveled after 3 more hours?
we know that
To find the distance, substitute the value of x in the function
so
For x=3 hours
For x=3, d(x)=300
That means -----> After 3 hours Carlos has traveled 300 miles at a constant speed of 60 mph
Part 2) How many miles will he have traveled after 5 more hours?
we know that
To find the distance, substitute the value of x in the function
so
For x=5 hours
For x=5, d(x)=420
That means -----> After 5 hours Carlos has traveled 420 miles at a constant speed of 60 mph
Part 3) How many miles will he have traveled after 8 more hours?
we know that
To find the distance, substitute the value of x in the function
so
For x=8 hours
For x=8, d(x)=600
That means -----> After 8 hours Carlos has traveled 600 miles at a constant speed of 60 mph
