Answer:
6 Nickels
42 Dimes
Step-by-step explanation:
There are 48 coins in total (nickels and dimes). Let the number of nickels be "n" and the number of dimes be "d". So we can write:
n + d = 48
or
n = 48 - d
In dollars, we know nickels are worth 0.05 and dimes are worth 0.10. In total there is $4.50, so we can write:
0.05n + 0.10d = 4.50
Now replacing first equation [n = 48 - d] into 2nd, we get and equation in "d" and solve for d first:
So, there are 42 dimes.
We know from before, n = 48 - d, so
n = 48 - 42 = 6
There are 6 nickels
Answer:
60%.
Step-by-step explanation:
We are asked to find the present occupancy rate of a 555-bed facility that only has 333 inmates booked.
The total number of beds is 555 and 333 beds are occupied by inmates. So we will find out 333 is what percent of 555.
Upon dividing 333 by 555 we will get,
Therefore, present occupancy rate is 60%.
Answer:

Step-by-step explanation:
Given: Sphere A and Sphere B are similar.
The volumes of A and B are 17 
and 136
The diameter of B is 6 cm.
To find: diameter of A
Solution:
Let R denotes radius of sphere A and r denotes radius of sphere B.
Radius of sphere A= R
Diameter of sphere B = 6 cm
So, radius of sphere B (r) = 
Volume of sphere is 
Volume of sphere A = 
Put r = 3 cm
Diameter of sphere A = 2 × Diameter
= 2 × 1.5
=3 cm
