Step-by-step explanation:
It came from nowhere. It makes no sense to add up the balance numbers. To illustrate, let's use a different example:
![\left[\begin{array}{cc}Spend&Balance\\100&400\\100&300\\100&200\\100&100\\100&0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7DSpend%26Balance%5C%5C100%26400%5C%5C100%26300%5C%5C100%26200%5C%5C100%26100%5C%5C100%260%5Cend%7Barray%7D%5Cright%5D)
Adding up the money you spent, and you get $500. Add up the balances, and you get $1000. But why would you add the balances? The 300 in the second line is included in the 400 in the first line. You can't add them together. You'd be counting the 300 twice.
Answer:
Each person will pay $ 7.20
Step-by-step explanation:
First we find the total bill
Pizza $18.60
Salad $2.50
<u>Soda $2.25</u>
Total $ 23.35
Sales Tax would be= 8 1/4% of $ 23.35 =$ 1.926= $ 1.93
Tip = 15% of $ 23.35= $ 3.5025
Total Bill paid= $ 23.35 + $ 1.93+ $3.50= $ 28.7825 or $ 28.78
Now dividing the bill among 4 persons = $ 28.78/4= $ 7.196 or $ 7.20
Paying the bill equally is better and convenient than paying alone as each person gets an equal share of pizza, salad and the soda.
Answer:
hypotenuse = 10
Step-by-step explanation:
If you can tell at first glance it is a 3,4,5 triangle (6,8,10)/2=(3,4,5). Then you know that c has to equal 5.
If not,
a^2+b^2=c^2
6^2+8^2=c^2
36+64=c^2
100=c^2
10=c
Answer:
110.5mm
Step-by-step explanation:
Formula : a = hb/2
a = 13(17)/2
221/2 = 110.5
Ok sure! Let's start with the marbles first. We have one red one blue and one green. There is a red and a blue cube. All we do is list the possible combinations of one marble and one cube. The answer would be : 1 blue marble, 1 blue cube. 1 red marble, 1 blue cube. 1 green marble, 1 blue cube. Then again but with the red cube. So in all, there are 6 possible combinations. Hope this helps. ☺️
