This answer calculates the resistance of an aluminum wire of specific dimensions. It begins by determining the cross-sectional area of the wire, then uses a formula incorporating resistivity, length, and area to calculate resistance. The final resistance of the wire is approximately 0.037 Ohms.
Explanation:To calculate the resistance of a piece of aluminum wire, we first need to figure out the cross-sectional area of the wire. As given, the diameter of the wire is 100 mils. To convert mils to cmils (circular mils), we square the diameter, thus 100^2 = 10,000 cmils is the cross-sectional area.
Next, we use the formula for resistance: R = ρL/A, where R is the resistance, ρ (Rho) is the resistivity of the material (aluminum, in this case), L is the length in feet, and A is the cross-sectional area in circular mils (cmils).
We need to convert the length from miles to feet (1 mile = 5,280 feet), so 2 miles = 10,560 feet. The resistivity of aluminum at 68°F is approximately 10.75 nanoOhms*meter, to convert this to Ohms*foot we multiply by 3.281, so ρ becomes approximately 35.28 nΩ/ft.
The resistance R can then be calculated as follows: R = ρL/A = (35.28 x 10^-9) x 10,560 / 10,000 = 0.037 Ohms, rounded to two decimal places.

Drag the correct steps into order to evaluate 42 + t/6 for t = 12.
The value of the expression for the given value of t is 44
From the question, we are to evaluate the given expression for t = 12
The given expression is
42 + t/6
To evaluate the given expression for t = 12, we will substitute 12 for t in the expression,
That is,
42 + t/6 becomes
42 + 12/6
NOTE: 12/6 = 2
Then, we get
42 + 2
= 44
Hence, the value of the expression for the given value of t is 44.

Hana rented a car for a week for $200 plus $0.25 per mile. After driving for one week, she owed the rental company $362.50.
Which equation represents the amount she paid to the rental company, and how far did Hana drive during the week?
$200 + $0.25m = $362.50; m = 650 miles
$200 + $0.50m = $250; m = 140 miles
$200 - $0.25m = $725; m = 2,250 miles
$200 - $0.25m = $362.50; m = 1,450 miles

t takes Dariya 35 seconds to download 5 songs from the Internet. How can the number of seconds it would take Dariya to download 7 songs at this rate be determined?
Answer:
The time it takes to download 7 songs is 49 seconds.
Step-by-step explanation:
It is about a division problem.
The first step is to determine how long it takes to download just one song. You must divide the total seconds by the total songs downloaded. The result would be the time required to download just one song.
[tex]\frac{35\, seconds}{5\, songs}=7\frac{seconds}{song}[/tex]
The previous value indicates that the download time is 7 seconds per song.
The second step is to determine how long it takes to download 7 songs. With the previous value in mind, you must multiply the time it takes to download one song by the 7 songs that Dariya wants to download, to obtain the total time it takes to download the 7 songs.
[tex]\frac{7\, seconds}{1\, song}\times 7\, songs=49\, seconds[/tex]
Thus, the time it takes to download 7 songs is 49 seconds.
A girl stands 160 cm tall she stands 360 cm away from a lamp post at night her shadow from the light is 90 cm long how high is the lam post
Final answer:
To find the height of the lamppost given the girl's height, distance from the lamp post, and shadow length, set up a proportion to calculate the lamp post's height.
Explanation:
A girl stands 160 cm tall and stands 360 cm away from a lamp post at night. Her shadow from the light is 90 cm long. How high is the lamppost?
Set up a proportion: Lamp post height / Girl's height = Lamp post shadow length / Girl's shadow length.
Substitute the values: Lamp post height / 160 cm = 360 cm / 90 cm.
Solve for the lamp post height: Lamp post height = (360 cm * 160 cm) / 90 cm = 640 cm.

A pair of diamond earrings has been marked up 50% and is now selling for $198.00. How much were the earrings before the mark-up?
Final answer:
The original price of the diamond earrings before a 50% markup that led to a final selling price of $198.00 was $132.00.
Explanation:
The question asks us to find the original price of the diamond earrings before a 50% markup that resulted in a final selling price of $198.00. To solve this, we use the markup formula, which is Final Price = (Original Price) × (1 + Markup Percentage). Here, the Final Price is $198.00 and the Markup Percentage is 50%, or 0.50 when expressed as a decimal.
First, we rearrange our formula to solve for the Original Price:
Original Price = Final Price ÷ (1 + Markup Percentage). Plugging in the given values, we have: Original Price = $198.00 ÷ (1 + 0.50) = $198.00 ÷ 1.50.
Doing the computation: Original Price = $132.00. Therefore, the earrings were priced at $132.00 before the 50% markup.

A bag contains 5 blue balls, 4 red balls, and 3 orange balls. If a ball is picked from the bag at random, what is the probability that it is a blue ball? Answers have been rounded to the tenths place.
Answer: Hello there!
in the bag we have:
5 blue balls, 4 red balls, and 3 orange balls.
This adds up to 5 + 4 + 3 = 12 balls in total.
If we took a ball at random, the probability tath this ball is blue is equal to the quotient between the number of blue balls and the total number of balls.
this is P = 5/12 = 0.4166
now we need to round it to the tenths place, this is the first number after the decimal point, in this case, a 4.
To round it we need to see the number that is after if it is 5 or bigger we round up, if is smaller than 5 we round down. In this case, is a 1, means that we need to round down
p = 0.4
If a ball is picked from the bag at random, the probability that the ball taken was a blue ball, is equal to p = 0.4

A pipe is 30 feet long. It needs to be cut into pieces that are each 2/3 feet long. How many pieces can be made from the pipe? Write the answer in simplest form.
To find the number of pieces, divide the length of the pipe by the length of each piece. The number of pieces that can be made is 45.
Explanation:To find the number of pieces that can be made from the pipe, we need to divide the length of the pipe by the length of each piece.
Length of each piece = 2/3 feet
Number of pieces = Length of pipe/Length of each piece = 30 feet / (2/3 feet)

The speed limit is posted in most areas, but, if not, the ___________ speed limit will be in effect.
When no specific speed limit is posted, the default speed limit applies. These defaults are set by local or state law and can vary. Drivers must adhere to these limits and drive safely for conditions.
Explanation:In most areas, when specific traffic speed limit signs are not posted, what's known as the default speed limit applies. These default speed limits are not posted on signs and instead are set by local or state law. It's important to stay aware of these limits in different areas, as they can vary. For instance, in many cities, the default speed limit is 25 mph unless otherwise posted. However, it should be noted that these default limits may not protect you from being pulled over if the police deem your speed unsafe for the current conditions. Thus, it's recommended to always drive at a speed that is appropriate for the conditions, even if you are technically within the speed limit.
