Perimeter = 4×
Where x = 5/7
4* 5/7
p= 20/7
The answer will be a mixed fraction
p= 2 6/7 units
Hope that helps!
Answer:
5√10, answer C
Step-by-step explanation:
You can use Pythagoras for this.
calculate the distance between the x coordinates (Δx), which is done by taking the biggest number and subtracting the the coordinates from each other. Aka 2 - - 3 = 2 + 3 = 5
Δy = 5 - - 10 = 15
then a^2 + b^2 = c^2 gives
5^2 + 15^2 = 250
c = √250
Then you still have to simplify. This is done by extracting the root out which results in an integer (a whole number), which is in this case 25.
√250 = √25 * √10 = 5√10, so answer C
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. ... Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.
The answer is D, like fractions are two fractions that have the same denominator.
