8 tenths is equal to 8/10, what is equal to 0,8. You can calculate the distance by multiplying 0,8 with the 1,6 mile course. That gives you 1,28 miles. Doing that for Sheila’s 9 tenth (0,9) gives you 1,44 miles. That means she swam 1,44-1,28 = 0,16 miles more than Simon.
Answer:
<em>Addison worked 5 hours</em>
Step-by-step explanation:
<u>Proportions
</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
The relationship between the number of kilograms of dough Addison prepares (y) is proportional to the number of hours he works on it (x).
Knowing he prepared y=30 kilograms of dough after t=3 hours, we substitute in the function:
30 = 3k
Solving for k:
k = 30/3 = 10
The relationship is:
y = 10x
If he prepared y=50 kg of dough, then:
50 = 10x
Solving for x
x = 50/10 = 5
Addison worked 5 hours
OK so the factor of 10 is 1 times 10 and 5 times 2
The first digit in will be in the hundreds place.
