The dimensions that could be the dimensions of a unit cube are:
A. 1 ft by 1 ft by 1 ftD. 1 mm by 1 mm by 1 mmA unit cube is a cube with side lengths of 1 unit, where the unit can be any length (such as inches, feet, centimeters, etc.). Therefore, to be the dimensions of a unit cube, all three side lengths must be equal to 1 unit.
Let's go through the options:
A. 1 ft by 1 ft by 1 ft: This represents a cube where all sides are 1 foot long. Since each side is 1 unit, this is a unit cube. (Correct)
B. 1 in by 2 in by 1 in: One of the side lengths is not 1 unit. Therefore, this cannot be the dimensions of a unit cube. (Incorrect)

A civil engineer is making a scale model of a highway on ramp. The length is 4 inches. The actual length on the ramp is 500ft. Ik scale model is 1/125 but how many times as long as the actual on ramp is the model?
Answers
Answer:
1500 Time the multiple of model scale is the actual length of the ramp.
Step-by-step explanation:
Given:
Actual length of ramp is 500ft
Modelling scale is 1/125.
To Find:
how many times as long as the actual on ramp is the model.
Solution:
Actual length is 500 ft
When Civil engineer is modelling the ramp on model then it is about 1/125 of the actual length present at that site.
So
=500*1/125
=4 inches
So on model scale engineer took inches as a unit for scale.
Actual length is 500 ft and model length is 4 inches
So 1 ft corresponds to 12 inches hence 500*12=6000 inches
6000 inches corresponds to 4 inches on model scale
i.e it is about 1500 time multiple of the model scale.
To find out how many times longer the actual on-ramp is than the model, we can use the following steps:
1. **Convert the model length to the same unit as the actual on-ramp:** Since the model's length is given in inches and the actual length is given in feet, we need to convert one of the measurements to the other unit so that they are comparable. Here, we will convert the model's length into feet. There are 12 inches in 1 foot, so to convert inches to feet, we divide by 12.
Model length in feet = Model length in inches / 12
Model length in feet = 4 inches / 12 inches per foot
Model length in feet = 1/3 foot
2. **Compare the actual length to the model length:** Once both lengths are in the same unit, we divide the actual on-ramp length by the model length to find out how many times longer the actual on-ramp is.
Times longer = Actual length / Model length
Times longer = 500 feet / (1/3 foot)
3. **Solve the division:** Now we solve the division by multiplying the actual length by the reciprocal of the model length.
Times longer = 500 feet * (3/1)
Times longer = 1500
So, the actual on-ramp is 1500 times longer than the model.
As for the mention of a scale of 1/125, this doesn't come into play in this specific comparison, as we are only comparing lengths. However, if we want to double-check the work, we can ensure that the scale is consistent with our findings.
Given a scale of 1/125, it means that 1 unit on the model represents 125 units in reality. If our model is 4 inches, that would mean:
Actual length at this scale = Model length * Scale factor
Actual length at this scale = 4 inches * 125
Actual length at this scale = 500 inches
Now, to convert this into feet:
Actual length at this scale in feet = 500 inches / 12 inches per foot
Actual length at this scale in feet = 41.6667 feet (approximately)
Now, this is not the actual length we've been given for the on-ramp (which is 500 feet), so it seems there might be some confusion with the scale provided. The scale factor is not needed when directly comparing the model's length to the actual on-ramp's length, as long as we convert into the same units for a fair comparison.

Answer:
1525.7 square meters, approximately.Step-by-step explanation:
Notice that the radius is 28 meters, and the angle of the orange sector is 137°. However, the angle of the blue sector is:
360° - 137° = 223°
The area of a circular sector is
[tex]A=\frac{\pi r^{2} \alpha}{360\°}[/tex]
Replacing given values, we have
[tex]A=\frac{(3.14)(28)^{2} (223\°)}{360\° }=\frac{548972.48}{360} \approx 1525[/tex]
Therefore, the right answer is the second choice.
Answer:
B. 1,525.7 square meters
Correct graph:
The correct graph is attached below.
Source:
Previous question that can be found at chegg
Step-by-step explanation:
Let's recall that the formula of the area of a sector of a circle is:
Area = π * r² * (C/360 ), where:
r is the radius of the circle of which the sector is part
C is the central angle in degrees
Replacing with the values provided, we have:
r = 28 meters
C = 360 - 137 = 223 (We're being asked about the blue sector area not the orange sector area)
Area = π * 28² * (223/360 )
Area = 3.1416 * 784 * 0.6194
Area = 1,525.7 m²
The correct answer is B. 1,525.7 m²

If people blink about 13 times per minute, how many times do they blink in 7 hours?
Answers
Answer:
Step-by-step explanation:
1 hour=60 min
7 hours=60×7=420 min
number of blink=420×13=5460
Final answer:
To calculate the number of times a person will blink in 7 hours at a rate of 13 blinks per minute, you multiply 13 by the total number of minutes in 7 hours (420) to get 5,460 blinks.
Explanation:
If people blink about 13 times per minute, we can calculate how many times they blink in 7 hours by multiplying the number of blinks per minute by the number of minutes in 7 hours. First, let's find out how many minutes are in 7 hours:
7 hours x 60 minutes per hour = 420 minutes
Now, we'll multiply the number of minutes by the number of blinks per minute:
420 minutes x 13 blinks per minute = 5,460 blinks
Therefore, a person will blink 5,460 times in 7 hours. This is a simple arithmetic multiplication problem that provides us with the total number of blinks over a given period.
Salim had a flock of 300 chickens 15%
Answers
Answer:
what is the question
Step-by-step explanation:
Salim has a flock of 300 chickens, and 15% of them are infected with a virus. He plans to take a Simple Random Sample (SRS) of 7 chickens to test for the virus.
Salim has a flock of 300 chickens, and 15% of them are infected with a virus. This means there are 45 infected chickens in the flock. To test for the virus, Salim plans to take a Simple Random Sample (SRS) of 7 chickens from the entire flock.
A Simple Random Sample involves selecting a subset of individuals from a larger population in such a way that each individual has an equal chance of being selected. This ensures that the sample is representative of the entire population.
Salim's decision to take a sample of 7 chickens is based on the practical constraints of time, resources, and cost. Testing all 300 chickens would be time-consuming and expensive. By taking a smaller sample, Salim can still obtain valuable information about the prevalence of the virus in his flock while minimizing costs and resources.
However, it's important to note that the accuracy of the sample depends on how well it represents the entire population. To ensure the sample is truly random and representative, Salim should use a random selection method, such as drawing names from a hat or using a random number generator.
Once Salim selects his sample, he can conduct tests to determine the presence of the virus in these chickens. The results of these tests will provide valuable insights into the overall prevalence of the virus in his flock, helping him make informed decisions about disease management and control.
The complete question is:
Salim had a flock of 300 chickens 15% of which are infected with a virus he plans on taking a SRS of 7 chickens to test for the virus.
The price of a gallon of milk at a particular convenience store has been recorded over the course of 10 weeks. At the end of the third week, the price $3.38 and at the end of the eighth week the price is $3.55. The price has been observed to increase exponentially.
Answers
Given:
The price of milk at the end of the third week = $3.38.
The price of milk at the end of the eighth week = $3.55.
To find:
The approximate increase in price of milk per week and the cost of milk at the end of the tenth week.
Solution:
To determine the increase in the price per week, we divide the difference in price over n number of weeks by n.
Here we know the prices of milk at the end of the third and the eighth week. There are 5 weeks between these two.
The approximate increase in the price of milk [tex]= \frac{3.55-3.38}{5} = \frac{0.17}{5} = 0.034.[/tex]
So there is an increase of $0.034 per week.
To determine the price at the end of the tenth week, we add the increase in price over two weeks to the price at the end of the eighth week.
The price of milk at the end of the eighth week = $3.55.
The increase in price over two weeks [tex]=2(0.034) = 0.068.[/tex]
The price of the milk at the end of the tenth week [tex]= 3.55+0.068=3.618.[/tex]
Rounding this off to the nearest cent, we get the price of milk at the end of the tenth week is $3.62.

Explanation:
When using more than one adjective, there is an order that should be followed (option D). In English grammar, adjectives are typically arranged in a specific order when they are used together before a noun. The general sequence is opinion, size, age, shape, color, origin, material, and purpose. Following this adjective order helps sentences sound natural to native speakers and makes the description clearer and easier to understand. For example, you might describe a sweater as a 'beautiful, small, old, red woolen sweater' to adhere to the standard adjective order.

The initial investment is $10,600, and the growth rate of the investment is 3.85%.
Answers
Answer:
The correct option is option (D)
The initial investment is $10,600 and the growth rate of the investment is 3.85%.
Step-by-step explanation:
The formula of compound interest:
[tex]A=P(1+r)^n[/tex]
A= Total amount after n years
P= Initial value of deposit
r= rate of interest compound annually
n= time is in year
Given expression is
[tex]A=10,600(1.0385)^x[/tex]
[tex]A=10,600(1+0.0385)^x[/tex]
Now we compare the given expression with the compound interest formula
So,
P= 10,600
r=0.0385 =3.85%
So, the initial investment is $10,600 and the growth rate of the investment is 3.85%.
