Answer:
C
Step-by-step explanation:
So the area of a circle is πr²
if the diameter of the sign 30 in then the radius is 15 in
Now Area of Circle = π(15 in)²
= 706.86
Thus by estimation the best answer is OPTION C
Answer: b
7(b-1)/b less than or equal to 0
Step-by-step explanation:
The total cost of rice and beans bought by Gabriel is 6b + 4r.
The simplified expression of the final cost is 4b + 3r.
<h3>What is simplification?</h3>
Simplification can be defined as a process of replacing a mathematical expression by the cancellation of common factors, regrouping of terms in the same variable to get the more simple form of the given expression.
Given that
6b + 4r represents the total cost of the rice and beans Gabriel bought.
He returns 2 bags of beans and 1 bag of rice.
This can be written as,

Then, the total number of bags of rice and beans is given as,

When we simplify the above equation, we get,

Hence we can conclude that the expression for rice and beans after the return is (4b+3r).

That question is asking for the time so your answer will specifically be in hours. And I'm not sure if you divide or you multiply but I'm pretty sure the correct answer is dividing because tomorrow so cancel the miles they will be left with hours. I don't know if that makes sense to you but it kind of makes sense to me somehow.
