Step-by-step explanation:
the answer explains it if you showed us the graphs we would be able to answer it for you
Step-by-step explanation:
Answer:
5:21
Step-by-step explanation:
To express the pairs in the same unit, 3 weeks has to be converted to days
7 days = 1 week
3 weeks = 3 x 7 = 21 days
the ratio can now be expressed as :
5 : 21
5:21 is already in its simplest form
Answer:
The proportionality constant is 2/5
Step-by-step explanation:
Here, we want to get the proportionality constant
Let us view the two points as being points on a line
The constant of proportionality will be the slope of the line that connects the two points
Mathematically, we can use the formula for the slope of a line
We have this as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (20,8)
(x2,y2)= (25,10)
m = (10-8)/(25-20) = 2/5
Answer:
75%
Step-by-step explanation:
- To know the answer, you should take into account that, 70 equals 1,75 times 40.
- This is because
.
- Then, if 70 equals 1,75 times 40, it is 0,75 = 75% greater than 40.
