Answer: there are 59059 lbs of gravel.
Step-by-step explanation:
In a mixture of concrete, there are four lbs of cement mix for each pound of gravel. This means that eight lbs of cement would be mixed for 2 pounds of gravel and 12 lbs of cement would be mixed for 3 pounds of gravel and 12. Therefore, the constant ratio of cement to gravel is 4:1
The total ratio is 4 + 1 = 5
If the mixture contains a total of 295295 lb of these two ingredients, then the number of pounds of gravel that are there is
1/5 × 295295 = 59059 lbs

Answer: 1)100ways and 2)90ways
Step-by-step explanation:
Given :-The 10 students who completed a special flying course are waiting to see if they will be awarded the one Distinction or the one Merit award for their efforts.
Ways can the two awards be given if the same student can receive both awards (i.e repetition is allowed)
=10×10=100ways
Ways can the two awards be given if the same student cannot receive both awards(i.e. repetition is not allowed)
=10×9=90ways
Well if you multiply 66.7 x 100 you get 6,670.0. When multiplying by numbers like 10, 100, 1,000, etc, just simply transfer the 0's. So in this case, there are 2 0's in 100, so you add 2 of the 0's behind 66.7. So when you add the 2 of the 0's you get 6,670.0 which should be your answer.
