Direct relationship
It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)
Answer: 25 hours
Step-by-step explanation:
Let r = rate, t = time
From 1st sentence,
5r x 12 = 3
60r = 3
r = 3/60 = 1/20
From the next,
4r x t = 5
4 x 1/20 x t = 5
4/20t = 5 = 25
Radius = √(7-(-1))² + (8-(-7))² = √8²+15² = √289 = 17
Let the point be (-15,y)
(-15-(-7))² + (y-(-1))² = 17²
⇒ -8² + (y+1)² = 17²
⇒ 64 + (y+1)² = 289
⇒ (y+1)² = 289 - 64 = 225
⇒ y+1 = +15 or -15
⇒ y = +15-1 or -15-1
⇒ y = 14 or -16
T<span>h</span>us, the point can be either (-15,14) or (-15,-16)
Answer:
864
Step-by-step explanation:
You need to divide 480 by 10. Then multiply the answer which is 48 miles per day. Then take the 48 times 8 for the next 8 days. Then add the answer of that which is 384 and add it to 480.
Hope this helps.
