Answer: The estimated 15% tip would be $4.50.

Step-by-step explanation: Basically, first you will need to round the bill amount, $31.51 to the nearest ten dollars. 31.51 rounded to the nearest ten dollars is $30. Next, you will need to find the estimated tip amount. To do this multiply $30 by the tip 15%. Before you can find the tip amount, you will need to covert 15% to a decimal. To convert 15% to a decimal, divide 15 by 100 to get 0.15. Now, you can multiply 30 by 0.15 to get 4.50. So, $4.50 would be the tip if $31.51 was rounded to the nearest ten dollars.

umka2103 [35]
The volume of a rectangular prism is equal to length*width*height. In this case, we have V = 243 and H = 3.
243 = LW(3), so LW = 81, where L & W are whole numbers greater than 1. There are only 3 possible pairs of values for this: 27*3, 9*9, and 3*27 (we cannot use 1*81 or 81*1, since we need dimensions > 1).
Part A. This could be true if Length = 9 in and Width = 9 in, as 9*9 = 81.
Part B. The claim could be false if Length = 27 in and Width = 3 in, as 27*3 = 81, but 27 is not equal to 3.
*Note that the width cannot be longer than the length.

Joe has fraction 5 over 6 pound of bird seed. He needs fraction 1 over 3 pound to feed the birds daily. Which of the rectangle m
Semenov [28]

Since Joe has 5/6 pounds left and he only needs 1/3 pounds each day to feed the birds, therefore the number of remaining day’s worth of seed is:

days = (5/6) / (1/3) = 2.5

The remaining seed can run up to 2 and half days. This also means that after 2 days, he is remained with ½ of 1/3 pound. ½ of 1/3 pound is equivalent to 1/6 pound. Therefore the correct rectangle model to use is:

<span>Rectangle model divided into 3 equal sections, two sections are labeled one-third and one section is labeled one-sixth, equaling two and one-half days.</span>
