Answer:
23 miles per hour. This is their speed.
Answer:
approximately 8.5
Step-by-step explanation:
So you can use the distance formula: which is derived from the Pythagorean theorem because normally x2-x1 would kind of give the distance length between x2 and x1 except sometimes it would be negative which wouldn't make much sense right? but it doesn't matter because it's being squared so the value ultimately becomes positive, and the same thing goes for the y-value. the distance between x2 - x1 really represents the base and y2-y1 represents the height and then adding them together gives the hypotenuse squared which is why you take the square root over the entire thing to find the distance, since the hypotenuse is the shortest distance between two points
Now all you have to do is plug the values in to get
Answer: 2 yards
Step-by-step explanation: there are 36 inches in a yard so divide 72 by 36 to get 2 which is the answer to the question

Step-by-step explanation:
in a rect.
b:l=1:4
let,
"x" & "4x"
perimeter=20cm
thus,
2(l+b)=20
x+4x=20/2
5x=10
x=10/5
x=2
also
4x=4×2
=8
also ,area=
l×b
=8×2
=16
thus,area=16
2:4 3:6 4:8
Any ratio equals 1:2 as long as you can divide the first number by itself to get 1 and the second number with the 1st number.
Example
2:4
Divide the first number by 2 and you get 1
Divide the second number by 2 and you get 2
So the ratio equals 1:2
