Sure thing!
So if we look at the function, it is an exponential, meaning that it is a number to the power of x
The graph can be described by the equation
y = a^x
If we look at the graph, one of the points on the line is (2, 16), the x value is 2 and the y value is 16
If we consider this along with the function for the graph, we can say that
16 = a^2
Just solve this for a and you’ll have your answer :)
Set up a proportion!
40 minutes / 5 holes = m minutes / 20 holes
Cross multiply.
800 = 5m
m = 160.
It will take him 160 minutes to dig 20 post holes.
Good luck Fabian!
Hope this helps
Answer:
1. 9/16 * 12/13 = 27/52
2. 7/10 * 5/28 = 1/8
Step-by-step explanation:
1.
9 / 16 * 12/13
9 * 12 = 108
16 * 13 = 208
108 / 208
Simplify:
27/52
2.
7 / 10 * 5 / 28
7 * 5 = 35
10 * 28 = 280
Simplify:
1/8
