Answer: 12 cm
Step-by-step explanation:
The masses of the spheres are proportional to their volums, and the cube of the ratio is k^3=135/5=27 ==> k=3
The greater radius is 3*4=12 (cm)
10x10=100

3 and 4/8 for question number one
To solve this problem you must apply the proccedure shown below:
1. You have that:
- He sales 13 gold rings and 18 silver rings in 9405 euros.
<span> - The cost of the silver ring is three times the cost of the gold ring.
2. Keeping the information above on mind, you have the following system of equations:
x: the gold ring.
y: the silver ring.
x+y=</span>9405
<span> x=3y
3. Then, you have:
(3y)+y=9405
y=9405/4
y=2351.23 euros
x=3y
x=3(</span>2351.23)
<span> x=7053.75 euros
The answer is:
- Gold ring=</span>7053.75 euros
- Silver ring=2351.23 euros<span>

Answer:
887,000 is the answer.
Step-by-step explanation:
When rounding a number to the nearest thousands place, pay close attention to the value in the hundreds place. For example, given that the 2 in 200 is less than 5 in 887,200, the 7 in the thousands place will not be rounded up and the hundreds place will round down.
