Answer:
The number of people on each bus is 32
Step-by-step explanation:
We are given
Total number of students =267
Total number of adults =21
So,
Total number of passengers = ( Total number of students)+(Total number of adults)
now, we can plug values
Total number of passengers =267+21
Total number of passengers =288
We are given
Number of buses=9
so,
Number of passengers on each bus = (total number of passengers)/( Number of buses)
now, we can plug values
Number of passengers on each bus is
So,
The number of people on each bus is 32
Set up a proportion. 6/10 = 9/x. cross multiply so x times 6 = 6x. And 10 times 9 = 90. so 6x=90. Then 90 and 6x divided by 6. which gets you x=15. The 9 ft tall elephant will cast a 15 ft shadow.
Answer:
2 cm, 9 cm, 10 cm
Step-by-step explanation:
To know if a combination is a triangle all you have to do is see if the combinations add up to 180
(2)(9)(10)=180 therefore it is a triangle.
All the other angles do not add up to 180 so they can't be triangles!!
(4)(10)(3)
=120
(5)(6)(11)
=330
(4)(5)(7)
=140
Answer:
3/4
Step-by-step explanation:
You can simplify it by looking for what divides into both numbers. The lowest possible number is 3 because it can go into both 9 and 12.
9/3=3
12/3=4
3/4
Answer:
It takes 75 years for the investment to quadruple in value
Step-by-step explanation:
Simple Interest
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this question:
4% simple interest per year, so I = 0.04.
Quadruple:
t when T = 4P.
The interest earned is:
Now we find the time.
It takes 75 years for the investment to quadruple in value
