1.Centigrams are larger than decigrams: NO
2.Hectometers are smaller than kilometers: YES
3.Dekaliters are larger than kiloliters: NO
.4.Grams are smaller than dekagrams: YES
Answer:
15 hours
Step-by-step explanation:
To solve this you start by setting up the proportion: = . This is because we want to know if 3 hours is 20 percent, then how much is 100 percent.
Next we cross multiply to get 300 = 20x
Now we can divide both sides by 20 to get 15.
To check the work we can multiply 15 by .2 and we get 3, so we know it's correct.
It is c. Hope this helps good luck my g

Step-by-step explanation:
Answer:
Range: 1 > x > 3
Step-by-step explanation:
We are given then function;
y = x³ - 6x² + 9x + 5
dy/dx = 3x² - 12x + 9
We want to find the range of values of x for which dy/dx > 0
Thus;
3x² - 12x + 9 > 0
Using quadratic formula, we have;
x = 1 and x = 3
Let's define the range;
try x = 0
3(0²) - 12(0) + 9 = 9
This is more than 0, so it is part of the solution.
Let's try x = 4
3(4²) - 12(4) + 9 = 9
This is more than 0 so it is part of the solution
Let's try x = 2
3(2²) - 12(2) + 9 = -3
This is less than 9 and so it's not part of the solution.
Thus the range of values of x for which dy/dx > 0 is;
1 > x > 3
