Answer:
Yes. They are proportional.
Step-by-step explanation:
The left side 0.777 is equal to the right side 0.777, which means that the given statement is always true.
True
you must factorize it as a difference of squares
a^2-b^2 = (a-b)(a+b),
9b^2-25 = (3b)^{2-(5)^2= (3b-5)(3b+5)
There’s no inverse for this function but d/dx is (1/((x+(pi/2))^2 +1)
Answer:
849
Step-by-step explanation:
To get the better deal, you should find the selling prices for a single tacos in both cases and compare the amounts.
In the first one, 10 tacos for $8.49
This means 1 tacos sells for $8.49/10 = $0.849
In the second one, 6 for $5.40, this means for a single tacos, the selling price is $5.40/6 =$0.9
The better deal is the first one that sells one taco for $0.849 compared to the second one that sells one tacos for $0.9
