Step-by-step explanation:
The total weight of a rock depends on its size and is proportional to its density. In this context, density is the weight per cubic inch. Let w denote the weight of the rock in pounds, s the size of the rock in cubic inches, and d the density of the rock in pounds per cubic inch. If a 48-cubic-inch rock weighs w pounds, write an equation that shows the proportional relation.
Answer:
[tex]d = \frac{w}{48}[/tex]
If [tex]\frac{1}{48} \\[/tex] is constant, say k
Then,
[tex]d = kw[/tex]
∴ 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
[tex]density (pounds/inch^{3} ) = \frac{weight(pounds)}{size (inch^{3}) }[/tex]
That is,
[tex]d = \frac{w}{s}[/tex]
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
[tex]d = \frac{w}{48}[/tex]
If [tex]\frac{1}{48} \\[/tex] is constant, say k
Then,
[tex]d = kw[/tex]
∴ d ∝ w
Hence, density is proportional to the weight OR weight is proportional to the density
The New Jersey Division of Fish and Wildlife keeps track of the beaver population in the Raritan River. They tagged 42 beavers and released them. A week later, they captured 54 beavers, including 14 tagged beavers. What is a good estimate of the beaver population in the Raritan River? There are approximately beavers in the Raritan River.
Answer:ratio is 14:54 = 42:B. Beavers = 162
Step-by-step explanation:
The ratio demonstrates how often one number is multiplied by another.
The approximate number of beavers exists 162.
What is meant by ratio?The ratio demonstrates how often one number is multiplied by another. When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage.
The relationship or comparison between two numbers in the same unit to determine how much larger one number is than the other is known as a ratio.
The 42 beavers were tagged and released by the New Jersey Division of Fish and Wildlife, which monitors the beaver population in the Raritan River. After a week, they had captured 54 beavers, 14 of which were marked. There are 54 Beavers in all, and 14 Beavers have tags.
Let the ratio be 14 : 54.
As 42 tagged beavers were released.
simplifying the above equation, we get
14 × 3 : 54 × 3
= 42 : 162
Therefore, the approximate number of beavers exists 162.

Do the binary numbers “0011” and “000011” have the same value or different values? Explain.
Using binary to decimal conversion, it is found that the numbers have the same values.
----------------------------------
0011
Converting from decimal, the number is given by:
[tex]0011 = 1\times2^0 + 1\times2^1 + 0\times2^2 + 0\times2^3 = 1 + 1 + 0 + 0 = 2[/tex]
----------------------------------
000011
Converting from decimal, the number is given by:
[tex]000011 = 1\times2^0 + 1\times2^1 + 0\times2^2 + 0\times2^3 + 0\times2^4 + 0\times2^5 = 1 + 1 + 0 + 0 + 0 + 0 = 2[/tex]
In both cases, the result of conversion is 2, thus, they have the same value.
A similar problem is given at https://brainly.com/question/7978210
To transform a binary number to a decimal number we need to multiply each of the components of the binary number by 2 to the power of the place value minus one, and sum all of that.
Based on this, we will see that 0011 and 000011 have the same value.
For example, the number 01 will be:
[tex]0*2^1 + 1*2^0 = 1[/tex]
The number 1010 will be:
[tex]1*2^3 + 0*2^2 + 1*2^1 + 0*2^0 = 1*8 + 1*2 = 10[/tex]
Now let's convert the two given numbers to decimals:
0011
[tex]0*2^3 + 0*2^2 + 1*2^1 + 1*2^0 = 3[/tex]
000011
[tex]0*2^5 + 0*2^4 + 0*2^3 + 0*2^2 + 1*2^1 + 1*2^0 = 3[/tex]
So exactly like in decimal numbers, adding zeros to the left side does not affect the value.

Josh wrote a whole number using the digits 8,4,7,2,9 and 0. Josh's number has a seven in the thousands and a 2 in the tens place. Josh's number is less then 500,000. Is Josh's number greater than 480,000?
Answer:
Step-by-step explanation:
Using the digits 8,4,7,2,9 and 0 to write a whole Number with 7 in the thousands place and 2 in the tens place :
The whole number is 6 digits long
100 thousand
10 thousand
Thousand = 7
Hundred
Tens = 2
Unit
Also the whole number is less than 500,000
Hence, number in the 100 thousand place is less Than 5,
Hence digit in the 100 thousand place = 4
Placing either 8 or 9 in the ten thousand place will mean That Josh's whole number is greater than 480,000

Today, 8 friends went out for lunch. Their total bill was $43.53, including tax and gratuity. One of them ordered only soda and needed to pay only $1.74. The
other 7 friends ordered the same daily special. How much did each of the other friends need to pay?
Answer:
5.97

Sleeping in college. A recent article in a college newspaper stated that college students get an average of 5.5 hrs of sleep each night. A student who was skeptical about this value decided to conduct a survey by randomly sampling 25 students. On average, the sampled students slept 6.25 hours per night. Identify which value represents the sample mean and which value represents the claimed population mean.
Answer:
Sample mean = 6.25 hours per night.
Population mean = 5.5 hrs of sleep each night.
Step-by-step explanation:
A sample mean is the mean of the sample collected. The 25 students surveyed by the student is the sample. The average sleep time derived from the sample is the sample mean.
A population mean is the mean of all the population. Here the population are college students. The population mean is the mean derived from studying the sleep duration of all the population - college students
