To find the value of Coach Velez's total bill, first we must figure out how much the total of all of the ice cream sundaes were.
To do this, we must multiply the number of sundaes (8) by the cost of each sundae ($5.35).
8 * 5.35 = $42.80
However, Coach Velez also left a tip of 15%. To find out how much Coach Velez tipped, we have to multiply his regular bill ($42.80) times the amount he is tipping (15% or 0.15)
$42.80 * 0.15 = $6.42
Finally, we just have to add the bill ($42.80) and the tip ($6.42) together to find Coach Velez's total amount.
$42.80 + $6.42 = $49.22
Coach Velez spent $49.22 in all.
5/7m=-55
1.) First of all they are multiplying so you do the opposite. In this case you divide 5/7 by both sides.
-55divided 5/7
Changes to
-55/1 x 7/5. See if you can cross cancel in this case you can. The -55 changes to a -11 and the 5 changes into a 1
Reminder: Remember when you divided by fractions you change the sign to a multiplication sign and then flip the next fraction over.
2.) After dividing you should get -77/1 or if you didn't cross cancel then you would get -385/5.
3.) If you get -385/5 then you would have to do 385 divided 5 and you would get -77.
4.) Checking your answer is 5/7•-77=-55.
5/7•-77 changes to 5/7•-77/1 and you can cross cancel it where the -77 changes to a -11 and 7 changes to a 1.
5.) You should get -55. If you didn't cross cancel then you would have gotten -385/77
6.) If got -385/77 then you would do -385 divided by 77. Your then should get -55.
7.) Look to see if the answer you got when you checked matches the answer in the problem. -55=-55
8.) Your answer is -77
Answer:
10 ways
Step-by-step explanation:
Step one:
given data
we have 3 passengers to be formed from 5
so the expression for the combination is given as
Cn, r)= n!/r!(n-r)!
substitute
C(5, 3)= 5!/3!(5-3)!
C(5, 3)= 5!/3!(2)!
C(5, 3)= 5*4*3/3!(2)!
C(5, 3)= 5*4*/2*1
C(5, 3)= 20/2
C(5, 3)=10 ways
