Which of the following is a unit of density?
Cubic meters
Square meters
Liters per cubic gram
Kilograms per cubic centimeter
The unit of density is:
Kilograms per cubic centimeter.
Step-by-step explanation:We know that the density of a substance is defined as the ratio of the mass of a substance to it's volume.
i.e.
[tex]\text{Density}=\dfrac{\text{Mass}}{\text{Volume}}[/tex]
Now, we know that the standard unit of the mass of a substance is: Kilograms(kg)
and the standard unit for a volume is: cubic centimeters(cm³)
Hence, we will get the unit for density as:
Kilograms per cubic centimeter

Find the taylor polynomial of degree three for the function x^0.2 about the point a=7. (your answers should include the variable x when appropriate.)
The function graphed shows the total cost for a taxi cab ride for x miles.
Select from the drop-down menus to correctly identify the taxi cab ride information provided by the graph.
The slope is _____ . 5, 3, 2.5, or 0.2
The slope represents __________. the total cost of the taxi ride, the total number of miles traveled, the cost per mile traveled, or the initial cost of the ride
1. To find for the value of the slope, we need to have the graph. But you forgot to include the graph in your question. So I will just help you find for it.
In the graph, find for any two pairs of x and y. Then use the equation:
m = (y2 – y1) / (x2 – x1)
where m is the slope, y2 is the 2nd y, y1 is the 1st y, x2 is the x of the 2nd y, x1 is the x of the 1st y
2. Actually the slope m represents the:
the cost per mile traveled
Answer:
The correct answer to this the slope is 2.5. And the slope represents the cost per miles traveled

Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet. Kerrie estimated correctly by rounding up. She has enough tile. The exact area is 104.5 square feet. Kerrie did not estimate correctly by rounding up. She does not have enough tile. The exact area is 104.5 square feet. Kerrie did not estimate correctly by rounding down. She does not have enough tile. The exact area is 104.5 square feet.
Kitchen = 11.3 * 9.25 = 104.525 square feet
Kerrie did not estimate correctly by rounding down. She does not have enough tile. The exact area is 104.5 square feet.
Kerrie did not estimate correctly by rounding down. She does not have enough tile. The exact area is 104.5 square feet.
What is an expression?
The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Kerrie is tiling the floor of a kitchen. The kitchen floor measures 11.3 feet by 9.25 feet. She orders enough tiles for 99 square feet.
Kitchen = 11.3 x 9.25 = 104.525 square feet
Therefore, Kerrie did not estimate correctly by rounding down. She does not have enough tile. The exact area is 104.5 square feet.

jessie uses 20 liters of gasoline to travel 200kilometers, how many liters of gasoline will he use on a trip of 700 kilometer?
Answer: He will use 70 liters of gasoline on a trip of 700 kilometer.
Step-by-step explanation:
Given : Jessie uses 20 liters of gasoline to travel 200 kilometers.
We assume that the rate of consumption of gasoline is contant.
By UNITARY METHOD, the amount of gasoline required for 1 kilometer distance = [tex]\dfrac{20}{200}=\dfrac{1}{10}[/tex] liter
Now, the amount of gasoline required for 700 kilometer distance = [tex]700\times\dfrac{1}{10}=70[/tex] liters
Hence, He will use 70 liters of gasoline on a trip of 700 kilometer.
To calculate how many liters of gasoline Jessie will use for a 700 km trip, the fuel efficiency is first determined to be 10 km/L from the given data. Using this information, it is found that Jessie will need 70 liters of gasoline for the 700 km trip.
Jessie uses 20 liters of gasoline to travel 200 kilometers. To determine how much gasoline Jessie will use on a trip of 700 kilometers, we first need to find the fuel efficiency of the vehicle. By dividing the distance traveled by the amount of gasoline used, we get the fuel consumption rate:
Fuel efficiency = Distance / Gasoline
Fuel efficiency = 200 km / 20 L
Fuel efficiency = 10 km/L
Now we know that the vehicle uses one liter of gasoline to travel 10 kilometers. To find out how many liters are needed for a 700 km trip, we apply the following:
Gasoline needed = Trip distance / Fuel efficiency
Gasoline needed = 700 km / (10 km/L)
Gasoline needed = 70 liters
Therefore, Jessie will use 70 liters of gasoline to travel 700 kilometers.

If p is true and q is false, the p -> q is always, sometimes, never true.
When p is false and q is true, then p or q is always, sometimes, never true.
If p is true and ~ q is false, then p -> ~ q is always, sometimes, never false.
If p is true and q is true, then ~ p -> ~ q is always, sometimes, never true.
If p -> q is true and q is true, then p always, sometimes, never is
1. If p is true and q is false, the p -> q is never true.
2. When p is false and q is true, then p or q is always true.
3. If p is true and ~ q is false, then p -> ~ q is never false.
4. If p is true and q is true, then ~ p -> ~ q is always true.
5. If p -> q is true and q is true, then p is always true.
Further Explanation:
The logic gates are used here.
Here, the symbol -> is for implication. Implication p-> q means that if p is true then q must be true.
So let us look at all the questions one by one.
1. If p is true and q is false, the p -> q is always, sometimes, never true.
p -> q
true -> false
The true should imply true so the given statement will never be true.
2. When p is false and q is true, then p or q is always, sometimes, never true.
false or true
We know that in or gate even if one input is true, the whole output is true. So this statement will be always true given p is false and q is true.
3. If p is true and ~ q is false, then p -> ~ q is always, sometimes, never false.
This translates to:
true -> true
So it will never be false.
4. If p is true and q is true, then ~ p -> ~ q is always, sometimes, never true.
This translates to:
false -> false
This will always be true.
5. If p -> q is true and q is true, then p is always, sometimes, never true.
If p->q is true and q is true then p will always be true. "Implies to" states that in p->q, in order for q to be true p has to be true. So p will always be true.

A triangle has sides of length 5 cm and 11 cm. What can you say about the length of the third side?
Final answer:
The length of the third side of the triangle must be greater than 6 cm and less than 16 cm, as per the triangle inequality theorem.
Explanation:
According to the triangle inequality theorem, the length of any side of a triangle must be less than the sum of the other two sides and greater than the difference between them. Therefore, the third side of a triangle with sides of length 5 cm and 11 cm must be longer than 6 cm (11 cm - 5 cm) and shorter than 16 cm (11 cm + 5 cm). To clarify, for any triangle with sides a, b, and c, where c is the longest side, the following must always be true: a + b > c and |a - b| < c.
