Answer:
If you keep adding a zero and keep getting the same number again and again. Than what you have is a repeating decimal.
Answer:
y = (1/2)x is proportional; (1/2)
Step-by-step explanation:
1. y= 1/2x Proportional; constant of proportionality is 1/2.
2. y=2x + 7 Not proportional because of the non-zero y-intercept.
3. x= y + 2 Not proportional (same a reason as for #2)
Answer:
The smaller bottle holds 12.5 ml of perfume.
====================
<h2>Given</h2>
- Two bottles of similar shape;
- Larger bottle has volume of 100 ml;
- The length of larger bottle is 10 cm;
- The length of smaller bottle is 5 cm.
<h2>To find </h2>
- The volume of smaller bottle.
<h2>Solution</h2>
Find the scale factor, the ratio of corresponding dimensions:
We know the volume is the function of three dimensions, therefore the ratio of volumes is the cube of the scale factor:
Substitute the known values and find the volume of small bottle:
The smaller bottle holds 12.5 ml of perfume.
