The model represents that 4 divided by 1/3 is 12.
Keep in mind that dividing fractions is the same is multiplying by the reciprocal. The reciprocal of 1/3 is 3/1, or just 3.
The image shows a 4 being divided into 4 groups of 3. When you count the boxes, you can see that there are 12. This means that whatever equation you do, you will want your answer to be 12.
As we stated above, 4 divided by 1/3 is really just 4*3, which equals 12. This confirms that the correct answer is B.
Let the number of dimes = xLet the number of quarters = y You know that each dime is worth $0.10You know that each quarter is worth $0.25 Using the variables above, we can write two equations that represents the total number of coins and total amount. x + y = 47 eq10.10x + 0.25y = 8 eq2 You can use the substitution/elimination method to solve for x and y.<span>3/6/2017 </span>| Michael J.<span>

Answer:
The two options yield the same price at 25 days.
Step-by-step explanation:
With the information provided, you can say that the option A would be equal to option B, which would be:
225-1x=250-2x, where x is the number of days that the item does not sell
Now, you can solve for x:
-1x+2x=250-225
x=25
According to this, the answer is that the two options yield the same price at 25 days.
Answer:
GROWTH
Step-by-step explanation:
Given the Exponential function;
A=10*
As we can see in the given function above:
the base number is 1.01 which is greater than 1 hence the quantity increases,
slowly at first and then very rapidly over its domain. The rate of growth becomes faster as time passes.
The growth "rate" (r) is determined as b = 1 + r.
In this situation, the rate growth is = 1.01 -1 = 0.01
Hope it will find you well.
