Answer:
If 
is constant, say k
Then,
∴ d ∝ w
Hence, weight is proportional to the density
Step-by-step explanation:
From the question,
Let w denote the weight of the rock in pounds
s denote the size of the rock in cubic inches and
d denote the density of the rock in pounds per cubic inch.
First, we will write the equation connecting w, s, and d.
We get
That is,
Now, given a 48-cubic-inch rock with weight w pounds, to show the proportional relation between the weight and the density, we will write
If is constant, say k
Then,
∴ d ∝ w
Hence, density is proportional to the weight OR weight is proportional to the density
Answer:
n = 80
Step-by-step explanation:
Plug in 80 for n to check:
17 + 80/5 = ?
17 + 16 = 33
Answer:
I think that is quadratic
How do you use a number line to solve 245-137 i thought i told a boy about that today but here it goes again you start from 0 to 245 and count back 137 and if you dont understand the concept of a number line here it goes a number line is a horizontal line going straight across with vertical lines going down hope that helps and if you still dont understand try this google a number line in images that should work your welcome!!!!!!!!!!!!!!!!!!!!!
Answer:
The percentage of the bags of the potato chips that are not cheddar-flavored is 25%. This is because there are 10 bags that are not cheddar-flavored and this divided by 40 bags, which is the total bags of the potato chips multiply by 100% gives 25%
Step-by-step explanation:
If there are 40 bags of potato chips and 30 are cheddar flavored, Then
40 - 30 = 10 bags are not cheddar flavored
Since the total bags is 40,
percentage potato chips that are not cheddar-flavored = 10/40 × 100%
= 25%
