Answer:
22 groups of ten
Step-by-step explanation:
121 plus 116 = 237
237 - 9 = 228
lets split 228 into parts
200
20
8
there are 20 groups of ten in 200
2 groups of ten in 20
and 8 has 0 it is a remainder
20 groups plus 2 groups = 22
22 groups of ten
this probobly isn't the easiest way but I don't know how but this is my thought process.
Answer:
A
Step-by-step explanation:
equivalent because each are 1:2
The wavefunction for a particle in a one-dimension box is a well-known problem, which has as a solution:
Ψ(x) = √(2/l) sin (nπx/l)
When the box has three dimensions, the general solution is simply the multiplication of the solutions for each dimension, therefore:
Ψ(x) = K · sin (n_x·π·x / l) · sin (n_y·π·y / l) · sin <span>(n_z·π·z / l)</span>
1) you do 144× 12 since you want to know how much all kids pay so its 1728 dollars.
2) they want 2 section a, 3 section b, and 2 section c, and sincc you want to know total you multiply number of tickets bought by cost per ticket, so its 2(10)+3(20)+2(30)=180 total cost.
3) sine they have 350 dollars yoy subtract cost of the ps4 from the amount they have and you get, 350-234=116 dollars remaining.
4) since they make 15 per lawn you write 15x, x representing number of lawns cut, and you set that equal to 225, so its 15x=225 then you divide 15 on both sides to get x= 15 lawns they need to cut.
5) you just divide 2/4 since they ate two of four slices and you get .5 then convert that to a decimal by moving decimal point 2 spaces over to get 50%.
6) Just add up all the costs of each song, so you get .99+1.19+1.5+.99 = 4.67 dollars as total cost.
7) since 60 min is in an hour and you have 30 min left over it would be 1hr and 30 min.
8) since its Monday through Friday which is only 5 days you multiply that by 4 weeks to get 20 days then you multiply by 30 since they study 30 min on each of those days, so you get 20×30 which is 600min of studying, but since it want is in hours divide 600 by 60 to get 10hrs of study.
Answer:
In 20 days he will waste 20 * 1/2 = 10 rotis . They have consumed 110 rotis in 20 days , so they have taken 110 + 10 = 120 rotis. (10 are wasted). Rosa ate x rotis and Varun ate 2x rotis . So x + 2x = 120 ⇒ 3x = 120 ⇒ x = 120/3 ⇒ x = 40
Varun ate 80 (2x) and Rosa ate 40 (x)
