Answer:
Step-by-step explanation:
1. 882/24 = 36.75 or 37 crates of milk
2. 3712 x 6 = 1902 yoghurts were sold
3. 94291 - 63512 = 30779
4. 91429 is greater by (91429-42929) = 48500.
10. 7 hours 55 mins
1 month and 3 days or 33 days.
Next bus would pass at 8:15am
It is a combination because the order in which the toppings are used does not change the result.
The formula of combination is C 17,3 = 17!/(3!14!) = 17x16x15/(3x2) = 17x8x5 = 680 different ways.
Well, the 89c bulb lasts twice as much, but costs less than twice as much. So, it's a better option. Here are two other ways to figure this out:
1) After 2000 hours, you will have used two 60c bulbs (each of them lasted 1000 hours). So, you will have spend 1.2 dollars. On the other hand, in the same 2000 hours, you would have needed only one 89c buls (which would have lasted the whole 2000 hours).
2) You can compute the dollars-per-hour ratio: spending 60c for 1000 hours means that you pay
dollars per hour. Similarly, the other bulb costs
dollars per hour, which is less.
What is that supposed to be 70, 7 or 700
Answer:
x = 3
y = 2
Step-by-step explanation:
<u>GIVEN :-</u>
- PQ = 2y + 3
- QR = 4y + 1
- RS = y + 5
- PS = 4x - 3
<u>TO FIND :-</u>
- The values of x & y for which PQRS will be a parallelogram
<u>FACTS TO KNOW BEFORE SOLVING :-</u>
In a parallelogram , pair of opposite sides are always equal in length.
<u>SOLUTION :-</u>
PQRS will be a parallelogram only when :-
1) Assume that PQ = RS.
∴ For y = 2 , PQ = RS.
2) Now, assume that PS = QR.
(Put y = 2 in the equation)
∴ For x = 3 , PS = QR.
<u>CONCLUSION :-</u>
For x = 3 & y = 2 , PQRS is a parallelogram.
