Underline the abstract nouns in the sentences. 1. Loyalty and patriotism are admired in citizens.
Answer:
Loyalty and patriotism are admired in citizens.
Answer:
Step-by-step explanation:
First of all, pick out the nouns.
Loyalty
Patriotism
Citizens
Now here's the thing. You can touch or smell or see or hear or feel (with your hands) concrete nouns. If you can't touch them etc., they are abstract nouns.
You can touch a citizen. If you don't believe me, go hug your mom. But how do you touch Loyalty and Patriotism? You can't. So those two nouns are your abstract nouns.

A new car is purchased for $47, 000 and over time its value depreciates by one half
every 4.5 years. What is the value of the car 23 years after it was purchased, to the
nearest hundred dollars?
Answer:
$1500
Step-by-step explanation:
you can figure it out by going in increments of 4.5 years because that is the info you have from the problem so
47000 4.5 years later is 23500
9 years = 11750
13.5y = 5875
18y = 2937.5
22.5 years later is 1468.75
22.5 years is about 23 years and to the nearest hundred dollars that is $1500 so that is the answer
Hope this helps! :)
we know the car depreciates every 4.5 years, and we also know its by one half or namely the depreciation rate is 50% of its value.

Relaciona el número con su lectura. Luego,selecciona la respuesta correcta
De acuerdo con la información presentada se puede inferir que la relación entre los números y letras es 1b, 2d, 3a, y 4c (opción a)
¿Qué es un número entero?Los números enteros son todos los números que pertenezcan a la categoría de los números naturales. Adicionalmente, se incluyen sus opuestos negativos incluyendo el número cero (0).
De acuerdo con lo anterior, debemos asociar los números con la forma correcta de escribirlos. Primero debemos tener en cuenta el número que está antes de la coma.
Por ejemplo el primer número solo puede relacionarse con las opciones B y D, debido a que estos comienzan con el 3.
Posteriormente, nos fijamos en el número que está después de la coma que en el caso del primer número sería cuatro mil ciento cinco millonésimos. Entonces el número 1, se asociaría con la letra b.
Entonces la opción 2 se debe relacionar con la opción restante que dice tres, antes de la coma, es decir, la opción d.
En cuanto a las opciones que comienzan con el 32, antes de la coma realizamos el mismo procedimiento de fijarnos en el número que está después de la coma. En el caso del número 3. tiene el número cuatrocientos un mil cinco millonésimas después de la coma, entonces sería la opción A.
Por último, la única opción que queda sería la opción C que se relaciona con el número 4.

Need help , can someone help me?
The answer is B.
Step-by-step explanation:
The min and max are 6 and 30, which is the same for all of the choices.
We need to find the median, which since there's an even number of elements we take the mean of the two elements in the middle (eg 20 and 22), which gives us 21. So the middle whisker will be on 21, so we know the answer is B or D.
Next, we need to find the upper and lower quartile. For these, we take the median again, but this time it's the median of the upper and lower halves (split by our median of 21). So, for the lower half, we have 6, 7, 9, 9, and 20. Since there's an odd number of elements this time, we just take the middle element, which is 9, so that's the lower whisker.
Then we do the same for the upper quartile. The upper half (above 21) is 22, 26, 28, 29, and 30. Since the number of elements is odd again, we just take the middle element, which is 28, so that is the upper whisker.
Plot the lower and upper whiskers and the median and you get graph B.

Answer:
our answer will be in quadrant 1 only.
Step-by-step explanation:
From the
cos−1(1) we have the side adjacent to ∠θ=1 and the side hypotenuse=2 . So this is a 30∘−60∘−90∘ triangle and θ=60∘therefore the opposite to ∠θ=√3.
Note that from the restrictions for the range of inverse circular functions cos−1x is restricted to quadrants 1 and 2 and since the argument is positive 12 our answer will be in quadrant 1 only.
The equation that can be used to find the measure of angle BAC is [tex]A = \tan^{-1}(\frac{12}5)[/tex]
To find the measure of angle BAC, we make use of the following tangent ratio
[tex]\tan(A) = \frac{12}5[/tex]
Next, we take the arc tan of both sides
[tex]\tan^{-1}(\tan(A)) = \tan^{-1}(\frac{12}5)[/tex]
So, we have:
[tex]A = \tan^{-1}(\frac{12}5)[/tex]
Hence, the equation that can be used to find the measure of angle BAC is [tex]A = \tan^{-1}(\frac{12}5)[/tex]

The last customer of the day calls telling you they purchased 96 meters of fencing to fence in a
circular area around their flagpole. They want to know how much area of concrete they'd need to
buy to cover the entire circular pad around the flagpole. Using their fence as the circumference,
calculate how much area they will need to cover with the concrete for their circular pad.
Answer:
Area = 733 m² (to the nearest meter)
Step-by-step explanation:
Formulae
Circumference of a circle = 2[tex]\pi[/tex]rArea of a circle = [tex]\pi[/tex]r²(where r is the radius of the circle)
Find the radius
circumference = 96 m
Using the circumference of a circle formula:
⇒ 2[tex]\pi[/tex]r = 96
⇒ [tex]\pi[/tex]r = 96 ÷ 2 = 48
⇒ r = 48 ÷ [tex]\pi[/tex] = 48/[tex]\pi[/tex]
Find the area
radius r = 48/[tex]\pi[/tex]
Using the area of a circle formula:
⇒ A = [tex]\pi[/tex]r²
⇒ A = [tex]\pi[/tex](48/[tex]\pi[/tex])²
⇒ A = 2304/[tex]\pi[/tex]
⇒ A = 733.3859778...
⇒ A = 733 m² (to the nearest meter)

Two trains start at he same point at the same time and simultaneously travel in opsonist direction. The speed of the first trains is 60 mph and the speed of the second train is 70 mph. How far apart will they be 3.5 hours?
Answer: 455 mph
Step-by-step explanation:
if train one is traveling one way at 60mph, then you have to multiply that by 3.5 to see how far it traveled in that amount of time.
60 x 3.5 = 210
then, you have to multiply 3.5 by 70mph, to see how far the second train has traveled in that amount of time
70 x 3.5 = 245
finally, since both trains are moving in opposite directions, you have to add up the distances together to get the final difference
210 + 245 = 455
Both the trains are in an opposite direction. after 3.5 hours they will be apart from a distance of 455.
What is speed?Speed can be calculated as the ratio of distance traveled to the time taken.
Speed x time = Distance
Two trains start at the same point at the same time and simultaneously travel in an opposite direction.
we need to find that how far apart will they be 3.5 hours.
The speed of the first train is 60 mph
Speed x time = Distance
= 60 x 3.5
= 210
The speed of the second train is 70 mph.
Speed x time = Distance
= 70 x 3.5
= 245
Since both trains are moving in opposite directions, we have to add up the distances together to get the final difference.
210 + 245 = 455
