77.5 answer

Step-by-step explanation:

The Planet Diner, being halfway between Lutherville and Otisburg, is 115 miles away from Clark.

To answer this question, we need to find out how far the Planet Diner is from Clark. Given that the Planet Diner is halfway between Lutherville and Otis burg, it is about half of the distance from Otis burg to Lutherville, which is 155 miles - 75 miles = 80 miles.

So, the distance from Lutherville to the Planet Diner is 80 miles / 2 = 40 miles. Since Lutherville is 75 miles away from Clark, the distance from Clark to the Planet Diner would be 75 miles + 40 miles = 115 miles.

Answer:

There is no solution.

0^-1 = 1/0

You can't divide by 0; therefore, there is no solution because the solution is undefined.

Zero to the power of negative one can be rewritten as one over zero. This fraction is technically equal to infinity, though it is also undefined.

First we need to simplify:

(-2x^2-4x+13 + (12x^2+2x-25) to get (−2x+12x​​ )+(−4x+2x)+(13−25).

Now we need to subtract them.

We are allowed to subtract like terms only that has same variable with same exponent.

[tex](5x^2+3)-(2x^2+4x-12)[/tex]

[tex]=5x^2+3-2x^2-4x+12[/tex]

[tex]=5x^2-2x^2-4x+3+12[/tex]

[tex]=(5-2)x^2-4x+(3+12)[/tex]

[tex]=(3)x^2-4x+(15)[/tex]

[tex]=3x^2-4x+15[/tex]

Hence final answer is [tex]3x^2-4x+15[/tex]

Answer:

(5x² + 3) - ( 2x² + 4x - 12) = 3x² - 4x + 15

Step-by-step explanation:

The given expression is

(5x² + 3) - ( 2x² + 4x - 12)

To find the subtraction result

(5x² + 3) - ( 2x² + 4x - 12) = 5x² + 3 - 2x² - 4x + 12

= 5x² - 2x² - 4x + 3 + 12

= 3x² - 4x + 15

Therefore the correct answer is

(5x² + 3) - ( 2x² + 4x - 12) = 3x² - 4x + 15

[tex]\$77,000[/tex] and the graph would fall at a slower rate to the right

Step-by-step explanation:

we have

[tex]y=Ao(0.79)^{x}[/tex]

Observing the graph

The initial value Ao of the truck is equal to the y-coordinate of the y-intercept of the graph

so

[tex]Ao=\$77,000[/tex]

If the depreciation rate was 15% per year, the new formula would be

[tex]y=Ao(1-0.15)^{x}[/tex]

[tex]y=Ao(0.85)^{x}[/tex]

[tex]y=77,000(0.85)^{x}[/tex] ----> the graph would fall at a slower rate to the right

= x³ + 3x² - 46

The diameter of circle is  288.84 units

As we know

Circumference of circle = 2*pi*r

where r is radius of the circle

Arranging the equation

C = 2 π r

r = C / 2 π

r = 907.46 / 2 π

r= 144.42

Since Diameter is double of radius so diameter is 2 x 144.42 = 288.84 units

Answer:

The correct answer option is C. 73.75.

Step-by-step explanation:

We are to perform division where 29.5 is the dividend while 0.4 is the divisor.

To make this division somehow easier, we can multiply both the dividend and the divisor by 10 to avoid the decimals.

So multiplying both the values with 10, we get:

[tex] \frac { 295 } { 4 } [/tex]

Now dividing 295 by 4, we get a quotient of 73.75.

X = number of correct answers

Y = number of incorrect answers

School A has 174 points and school B has 102 points.

A = 174

B = 102

School A has the same number of correct and incorrect answers during the final round.

A = 174 + 10X - 6Y

School B gives no incorrect answers and the same number of correct answers as school A.

B = 102 + 10X

The contest ends with the two schools tied.

Score = 174 + 10X - 6Y = 102 + 10X

174 + 10X - 6Y = 102 + 10X

Answer:

The solutions to the equation are -3,-2,2

Step-by-step explanation:

x^3+3x^2=4x+12

Subtract 4x +12 from each side

x^3+3x^2-4x-12=4x+12-4x-12

x^3+3x^2-4x-12=0

I will use factoring by grouping

x^3+3x^2     -4x-12=0

I will factor out x^2 from the first group and -4 from the second group

x^2 (x+3) -4(x+3) =0

Now we can factor out (x+3)

(x+3) (x^2-4) =0

We can use the zero product principle since the right hand side is equal to 0

x+3 =0            x^2-4 =0

x+3-3=0-3        x^2 -4+4=0+4

x=-3                    x^2=4

                           Take the square root of each side

                            sqrt(x^2) = sqrt(4)

                                      x=±2

The solutions to the equation are -3,-2,2

Answer:

Step-by-step explanation: the answer is true

The given statement is true. Both functions and relations can be represented by mapping diagrams is true statement.

Mapping diagrams: A mapping diagram is a visual representation that shows the relationship between the elements of a domain and the corresponding elements in a co-domain or range.

Functions: A function is a specific type of relation where each element in the domain is mapped to exactly one element in the co-domain. In a mapping diagram for a function, each element in the domain is represented by an arrow pointing to its corresponding element in the co-domain.

Representing functions with mapping diagrams: To represent a function using a mapping diagram, follow these steps:

Identify the elements in the domain and co-domain of the function.

Draw a set of arrows from each element in the domain to its corresponding element in the co-domain.

Make sure that each element in the domain has only one arrow pointing to it from the co-domain, indicating the one-to-one mapping characteristic of functions.

Relations: A is a more general concept that describes any set of ordered pairs consisting of elements from a domain and co-domain. A relation can have multiple outputs for a single input, unlike a function.

Representing relations with mapping diagrams: To represent a relation using a mapping diagram, follow these steps:

Identify the elements in the domain and co-domain of the relation.

Draw arrows from each element in the domain to all the corresponding elements in the co-domain, representing the multiple outputs or mappings.

In summary, mapping diagrams can be used to represent both functions and relations. Functions have a one-to-one mapping, whereas relations can have multiple mappings for a single input. Mapping diagrams provide a visual way to understand and represent the relationships between the elements of a domain and co-domain.

Therefore, the given statement is true. Both functions and relations can be represented by mapping diagrams is true statement.

Answer: 113.0973  [tex]in^{2}[/tex]

Step-by-step explanation:

If the diameter of the circle is 12", then the radius is 6" (half the diameter), and the area "A" is (approximately) 3.14 * 6^2 or about 113.04 sq. in. The calculation is approximate because 3.14 is a rounded value for pi. But the correct answer is 113.0973 not 113.04 because it's giving you the answer compared to SQUARE, but we need the answer in Inches. So that was just an example.

Saturday = [tex]3\dfrac{2}{3}[/tex]

Sunday = [tex]1\dfrac{4}{5}[/tex]

Now we actually have two different fractions with different denominators.

We can solve this first by converting the mixed numbers into improper fractions.

[tex]3\dfrac{2}{3}=\dfrac{9+2}{3}[/tex]

[tex]3\dfrac{2}{3}=\dfrac{11}{3}[/tex]

Now how did I do that?

First we take the denominator and multiply it to our whole number, then add the product to the numerator.

Let's proceed to the next mixed fraction.

[tex]1\dfrac{4}{5}=\dfrac{5+4}{5}[/tex]

[tex]1\dfrac{4}{5}=\dfrac{9}{5}[/tex]

We are then left with:

[tex]\dfrac{11}{3}-\dfrac{9}{5}[/tex]

Since we cannot subtract them directly because they have different denominators, we need to find the LCD of both denominators.

[tex](\dfrac{5}{5}) \dfrac{11}{3}-\dfrac{9}{5}(\dfrac{3}{3})[/tex]

[tex]\dfrac{55}{15}-\dfrac{27}{15}[/tex]

Now that they have similar denominators, we can then proceed to subtract them to each other.

To add the fractions of cheese Alana bought (3/8 and 1/4), you cannot use fractions with a common denominator, for instance, 6/16 and 4/16.

The question asked by the student is about adding fractions, and in the context given, the fractions represent pounds of cheese Alana bought. The two fractions in question are 3/8 and 1/4. To find out the total amount of cheese Alana bought, you need to add these fractions. Given that the two fractions have different denominators, you cannot use any pair of fractions with a common denominator to find the total. Hence, a pair of fractions like 6/16 and 4/16 (these fractions are equivalent to 3/8 and 1/4) cannot be used to determine the total cheese Alana bought.

The fractions cannot be used to find the total weight of cheese if they do not have a common denominator. For example, 1/3 and 1/5 cannot be used to find the total weight of cheese because their LCM is 15, and neither fraction can be converted to have a denominator of 15.

To determine which pair of fractions cannot be used to find the total weight of cheese, we need to consider the concept of least common multiples (LCM). The LCM is the smallest positive integer that is a multiple of both denominators.

In this case, the denominators of the two fractions are 8 and 4. The LCM of 8 and 4 is 8.

If we can convert both fractions to have the same denominator of 8, then we can add the numerators to find the total weight of cheese. However, if the fractions cannot be converted to have the same denominator of 8, then we cannot use them to find the total weight of cheese.

Let's convert the first fraction, 3/8, to have a denominator of 8. We can do this by multiplying the numerator and denominator by 1:

3/8 * 1/1 = 3/8

Now let's convert the second fraction, 1/4, to have a denominator of 8. We can do this by multiplying the numerator and denominator by 2:

1/4 * 2/2 = 2/8

Since we were able to convert both fractions to have the same denominator of 8, we can use them to find the total weight of cheese. The total weight of cheese is 3/8 + 2/8 = 5/8.

Therefore, the pair of fractions that cannot be used to find the total weight of cheese is any pair that does not have a common denominator. For example, the fractions 1/3 and 1/5 cannot be used to find the total weight of cheese because their LCM is 15, and neither fraction can be converted to have a denominator of 15.
