Answer: the answer is D

Step-by-step explanation:

The length of third side of the triangle ABC cannot be D) 35.

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

Given that,

For a triangle ABC,

Length of side AB = 8 units

Length of side BC = 25 units

We have that,

The third side of the triangle will be in the range of the sum and the difference of the other two side lengths.

So side AC can be in the range,

25 - 8 < AC < 25 + 8

17 < AC < 33

Hence the length 35 cannot be possible since it does not contain in the range.

Answer:

Yes, it would be all real numbers. If a negative was more than the absolute vaule, it would be false

Step-by-step explanation:

|x-6|>-2

pos. neg.

The the absolute vaule is ALWAYS positive so like I said before if the sign was facing towards the -2 it would be false

4 |x-6| (greater than or equal to)> -8

First you have to divide 4 on both sides since its outside the absolute vaule

then you will be left with

|x-6|>-2

since the 2 is a negative, you may think that this is automatically no solution, but sadly it isn't.

since the sign says the pos. sign is greater the equation is true and "all real numbers"

Answer:4

Step-by-step explanation:

Take the denominator and set it to equal 0. We do this since the expression will be going towards 0, but never actually hitting it. This is due to you NEVER being able to divide by zero. Research about why, it's actually quite fascinating! So the entire expression would forever be chasing what ever makes the denominator equate to zero.

So, let's do that.

Set 2x-8 equal to zero.

0=2x-8

Once we do some simple math, we find that 4 is what we're looking for.

Answer:

[tex]\frac{1}{2}\times \text{Boundary of county Harding touching Adams}\times \text{Boundary of county Lincoln touching Adams}[/tex]

Step-by-step explanation:

In the figure attached, map shows the dimensions of the 5 counties in a Midwestern state.

Adams county has the triangular boundaries.

Since area of triangle is represented by the expression [tex]\frac{1}{2}(\text{Base})\times (\text{Height})[/tex]

Base represents the boundary of county Harding touching Adams = 18 mi.

Height represents the boundary of county Lincoln touching Adams = 10 mi

Therefore, expression representing the area of Adams county will be

[tex]\frac{1}{2}\times \text{Boundary of county Harding touching Adams}\times \text{Boundary of county Lincoln touching Adams}[/tex]

= [tex]\frac{1}{2}18\times 10[/tex]

Option B.

Step-by-step explanation:

The given equation is

[tex]49y-8=89[/tex]

We need to find a word problem that can represented by the given equation.

The required problem is : A water filter filters 49 ounces of water per day. The first 8 ounces of water cannot be consumed and must be dumped out. How many days will it take the water filter to produce 89 ounces of consumable water?

Let y be the number number of days it take the water filter to produce 89 ounces of consumable water.

Total water filtered in y days = 49y

The first 8 ounces of water cannot be consumed and must be dumped out.

Total consumable water filtered in y days = 49y - 8

We need to produce 89 ounces of consumable water.

[tex]49y-8=89[/tex]

Therefore, the correct option is B.

There are 10 4-seated cars at the carnival.

We are given that there are two types of cars at the carnival, one with 2 seats and one with 4 seats. We also know that there are a total of 25 cars and they can seat 70 children in total.

Let's assume the number of 2-seated cars is x and the number of 4-seated cars is y. We can set up a system of equations to represent the given information:

We can solve this system of equations using substitution or elimination method. Let's solve it using elimination method:

So, there are 10 4-seated cars at the carnival.

https://brainly.com/question/14460430

#SPJ2

The carnival ride question can be solved using a system of equations with two variables representing the number of 2-seated and 4-seated cars. After setting up and solving the equations, we find there are 10 4-seated cars and 15 2-seated cars.

To tackle this problem, we need to set up two equations based on the seats and cars information given. Let's define x as the number of 2-seated cars and y as the number of 4-seated cars. The problem states that there are a total of 25 cars, which gives us the equation:

x + y = 25

Furthermore, we know that the total number of seats across all cars is 70. Since 2-seated cars contribute 2x to the total number of seats and 4-seated cars contribute 4y, we have the second equation:

2x + 4y = 70

To solve for y, we can manipulate these equations using substitution or elimination. For this example, let's use elimination. Divide the second equation by 2 to simplify it:

x + 2y = 35

Now subtract the first equation from this simplified second equation:

y = 35 - 25

y = 10

So, there are 10 4-seated cars. To find the number of 2-seated cars (x), substitute y back into the first equation:

x + 10 = 25

x = 25 - 10

x = 15

Thus, there are 15 2-seated cars.

The correct fraction is [tex]\(\frac{456}{1000}\)[/tex].

To convert the decimal 0.456 to a fraction, one can follow these steps:

1. Write the decimal as a fraction with a denominator of 1000, since there are three digits after the decimal point. This gives us [tex]\(\frac{456}{1000}\)[/tex].

2. Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of 456 and 1000 is 8.

3. Divide both the numerator and the denominator by 8 to get the simplified fraction:

[tex]\(\frac{456 \div 8}{1000 \div 8} = \frac{57}{125}\)[/tex].

Therefore, the decimal 0.456 expressed as a simplified fraction is [tex]\(\frac{57}{125}\)[/tex].

Since Alisa wrote a comparison for set b using the ten thousands place. The strategy that she could have used is 1000¹⁰

So, Alisa's strategy for comparing numbers in Set B using the ten thousand place involves focusing on a specific digit position to simplify the comparison process.

In Set B, the numbers are 492,111 and 409,867. By looking at the ten thousand place, which is the fourth digit from the right, Alisa can break down the comparison to:

Since 2 is greater than 0, Alisa can quickly deduce that 492,111 is larger than 409,867. This strategy is based on the idea that when numbers are similar in size, comparing them digit by digit can help us easily figure out which one is bigger.

Answer:

Step-by-step explanation:

N is between points M and O

MN = x

MO = 3x - 6

NO = x + 1

The way it reads MN + NO = MO

x + x + 1 = 3x - 6

2x + 1 = 3x - 6

2x - 2x +1 = 3x -2x - 6

1 = x - 6          

1 + 6 = x

x = 7

MO = 3x - 6

MO = 3*7 - 6

MO = 21 - 6

MO = 15

The numerical length of MO, given MN = x, MO = 3x - 6, and NO = x + 1, is 15.

Given the conditions of the problem, we can create the equation MO = MN + NO based on segment addition postulate in Geometry. This implies: 3x - 6 = x + x + 1, or 3x - 6 = 2x + 1. Solving this equation for x, you get x equals 7. Substituting x = 7 into MO = 3x - 6 gives you: MO = 3(7) - 6 = 21 - 6 = 15. So, the numerical length of MO,  given MN = x, MO = 3x - 6, and NO = x + 1, is 15.

Answer:

39

Step-by-step explanation:

This weird notation just means we are going to put one equation inside the other, and then solve.

Makes more sense when you write it like this:

g ( f ( x ) )

To solve, we are going to take the 3, plug it into the f ( x )

g ( f ( 3 ) )

^ This makes it a lot easier to understand what we have to do.

----------------------------------------------------------------------------------------------------------

Ok, so now we evaluate f ( x ) at 3.

4 ( 3 ) - 2

f( x ) = 10

Then we plug it into g ( x )

4 ( 10 ) - 1

= 39

Here's how it looks in total:

4 ( 4 ( 3 ) - 2 ) - 1 = 39

-4 is your answer.

Final answer:

To evaluate the expression, divide 12 by 3, multiply by -3, find the absolute value of -8, and sum the results, obtaining -4 as the correct answer.

Explanation:

The student asked to evaluate the expression 12 ÷ 3 × (-3) + |-8|. To solve this, we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, we perform the division: 12 ÷ 3 = 4.

Next, we multiply the result by -3: 4 × (-3) = -12.

Then, we evaluate the absolute value: |-8| = 8.

Lastly, we add the results of the multiplication and the absolute value: -12 + 8 = -4.

Therefore, the correct answer is b: -4.

Answer: [tex]\dfrac{5}{7}[/tex] of an hour

Step-by-step explanation:

Given : It takes [tex]\dfrac{3}{7}[/tex] of an hour to paint [tex]\dfrac{3}{5}[/tex] of a room.

i.e. Time taken to paint [tex]\dfrac{3}{5}[/tex] of a room.= [tex]\dfrac{3}{7}[/tex] of an hour.

Using Unitary Method, we have

Time taken to paint one room.= [tex]\dfrac{3}{7}\times\dfrac{5}{3}[/tex] of an hour.

⇒Time taken to paint one room=[tex]\dfrac{5}{7}[/tex] of an hour.

Hence, it will take [tex]\dfrac{5}{7}[/tex] of an hour to paint one room.

To paint one full room, it takes approximately 5/7 of an hour based on the given information that it takes 3/7 of an hour to paint 3/5 of a room.

Given that,

It takes 3/7 of an hour to paint 3/5 of a room.

The task is to determine how long it takes to paint one full room.

To find out how long it takes to paint one full room,

First, calculate the amount of time required to paint one-fifth of a room. Since it takes 3/7 of an hour to paint 3/5 of a room,

Set up a proportion:

(3/7 hour) / (3/5 room) = (x hour) / (1 room)

By cross-multiplying, we get:

(3/7) (1 room) = (3/5) (x hour)

Simplifying further, we have:

3/7 = (3/5) * (x hour)

To isolate x, we divide both sides of the equation by (3/5):

(3/7) / (3/5) = x hour

This simplifies to:

(3/7) * (5/3) = x hour

15/21 = x hour

x = 5/7 hour

Therefore, it takes 5/7 of an hour to paint one full room.
