Answer 1
Answer:

let's firstly convert all the mixed fractions to improper fractions and then sum them up.

\bf \stackrel{mixed}{4(1)/(12)}\implies \cfrac{4\cdot 12+1}{12}\implies \stackrel{improper}{\cfrac{49}{12}}~\hfill \stackrel{mixed}{2(1)/(4)}\implies \cfrac{2\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{9}{4}} \n\n\n \stackrel{mixed}{3(2)/(3)}\implies \cfrac{3\cdot 3+2}{3}\stackrel{improper}{\cfrac{11}{3}} \n\n[-0.35em] ~\dotfill

\bf \cfrac{49}{12}+\cfrac{9}{4}+\cfrac{11}{3}\implies \stackrel{\textit{using an LCD of 12}}{\cfrac{(1)49+(3)9+(4)11}{12}}\implies \cfrac{49+27+44}{12}\implies \cfrac{120}{12}\implies 10

Answer 2
Answer: You add the base and to sides which will equal 10 5/12

Using Victoria's simulation, what is the probability of pulling a blue marble and the coin landing tails up?
540/2500
48/50
38/50
360/2500

Answers

Answer: (540)/(2500)

Step-by-step explanation:

Formula:

\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}

Using Victoria's simulation :

Total number of outcomes = Total number of times marbles rolled x Total number of times coin flipped

= 50 x 50 =2500

Favorable outcomes = Total number of times pulling a blue marble and the coin landing tails up

= Number of times blue marble rolled x Number of times coin flipped to tail

= 18 x 30=540

Now, the  the probability of pulling a blue marble and the coin landing tails up will be :-

=(540)/(2500)

Answer:

C. 540/2500

Step-by-step explanation:

18 times 30=540

50 times 50= 2500

PLEASE HELP!! Angelo and Jimmy went shopping. Angelo had a. dollars in his wallet. He spent 1/3 of that money on new jeans. Jimmy had j. dollars in his wallet. He spent 1/2 of that money on a new jacket. Jimmy had more money left than Angelo. Which expression shows the difference between the amounts of money, in dollars, that each boy had left.

Answers

Okay, so Angelo had a dollars and spent 1/3 of that. So he spent 1/3a

Then, the amount he has left can be denoted as: (a - 1/3a)


Jimmy had j dollars and spent 1/2 of it:

So the amount he has left can be denoted as (j - 1/2j)


Since jimmy had more money left, you would subtract the amount angelo has from the amount that jimmy has left.

So: (j - 1/2j) - (a - 1/3a).
