AD : AB = 12:18
12:18 = 2:3
Answer:
7 units
Step-by-step explanation:
Given that :
house is at (−4, 10). Her school is at (−4, 3)
House location = (-4, 10)
School location = (-4, 3)
Distance from house to school (d) :
Distance between two points :
x = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
x1 = - 4 ; y1 = 10 ; x2 = - 4 ; y2 = 3
d = sqrt[(-4 - (-4))^2 + (3 - 10)^2]
d = sqrt[(-4 + 4)^2 + (-7)^2]
d = sqrt(0 + (-7)^2)
d = sqrt(49)
d = 7 units
Answer:
if you want to build bridges the Pythagorean theoum is what many people use.
For this case we have that by definition:
Where,
- <em>s: speed
</em>
- <em>d: distance
</em>
- <em>t: time
</em>
Therefore, we have then:
Thus, replacing values we have:
Answer:
An expression that calculates the speed in meters per second of an object that travels to distance of 40 m every 10 s is:
Option C.
