Answer:
50 minutes
Step-by-step explanation:
10 / 0.2 = 50
It takes 5 minutes for the snail to travel 1 inch, multiply that by 10 and we get 50 minutes.
Answer:
gloves cost $5
hats cost $4
Step-by-step explanation:
four pairs of gloves and four hats for $36.00
4g + 4h = 36
three pairs of gloves and four hats for $31.00
3g + 4h = 31
-------------------------
Subtract the second equation from the first
4g + 4h = 36
-( 3g + 4h = 31 )
––––––––––––
g = 5
gloves cost $5
substitute for g = 5 into either equation
4(5) + 4h = 36
20 + 4h = 36
Subtract 20 from both sides
4h = 16
Divide both sides by 4
h = 4
hats cost $4
Answer:
Step-by-step explanation:
The typical equation for the area of a circle is 
. Since the answer choices are in terms of <em>d</em>, the diameter of the circle, you will need to find <em>r</em> in terms of <em>d</em>.
To find <em>r</em> in terms of <em>d</em>, you know that the diameter of a circle is two times its radius. As an equation, this is
, or solving for <em>r</em>,
.
Now that you have an equation for <em>r</em> in terms of <em>d, </em>you can substitute <em>r</em> with 
from the original equation.
Answer:
The height of the actual picture frame
Step-by-step explanation:
I know this because the height of the picture frame depends on the height of the picture.
Answer: c) increase
Step-by-step explanation:
- A sample is a finite subset of the entire population on which research statistical test regarding his/ her objective .
As the sample size increases it comes closer to the population size, and so converge to a better result of researcher's analysis.
It means the size of the sample is proportional to the power of their statistical tests.
∴ As the size of the sample increases the power of statistical test increases.
Hence, If a research team increases the sample size for a study, the power of their statistical tests will <u>increases</u>.
Therefore , the correct answer is : c) increase
