as you already know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

Answer:
<h2>The product is 0.68</h2>
Step-by-step explanation:
A product means we are multiplying. we are multiplying 0.34 and 0.02 which is 0.68
It would help if you find common denominator... 12
so 1/3 times 4 both the numerator and denominator
4/12
and 3/4 times by 3 both the numerator and denominator
9/12
the recipe calls for 4/12 cup of oil and you have 9/12
two batches would be 8/12 cups of oil, you have 9/12 that is just enough for the recipe for two batches...
now to simplify it again, 1/3 + 1/3 = 2/3 and 2/3 is less than 3/4
the answer would be the upper right
Answer:
150°
Step-by-step explanation:
to find the individual angle of a REGULAR dodecagon (which means that all sides are equal), you'd use the equation I(individual angle)= (n-2)×180/n
N is number of sides. The number of sides on a dodecagon is 12. So, substitute N for 12
I= (12-2)×180/12 which simplifies to 10×180/12
10×180= 1800
1800/12 = 150
so, an individual interior angle of a dodecagon is 150°
