Answer: -5/6

Step-by-step explanation: 53/6= 8 5/6 -5/6=8

Answer:

9/12 or 2/3

Step-by-step explanation:

Make both fractions have the same denominator by finding their least common multiple

1x12 = 12                1x3 = 3

2x6 = 12                3x1 = 3

3x4 = 12

4x3 = 12

6x2 = 12

12x1 = 12

In which case it would be 12.

1/3 would be 4/12

5/12 + 4/12 = 9/12

which is also 2/3 if your teacher wants the simplest answer

Answer:

1/8

Step-by-step explanation:

On a die, if you want an even number, the probability will be 1/2. However, the probability on 3 dices is 1/2 x 1/2 x 1/2.

=> 1/2 x 1/2 x 1/2

=> 1/2³

=> 1/8

Therefore, 1/8 is the answer.

Answer: 6 pounds

Step-by-step explanation:

If 1 pound of raw spaghetti makes 5 cups of cooked spaghetti, then we can set up a proportion:

1 pound raw spaghetti : 5 cups cooked spaghetti = x pounds raw spaghetti : 30 cups cooked spaghetti

To solve for x, we can cross-multiply and simplify:

1 * 30 = 5 * x

30 = 5x

x = 6

Therefore, 6 pounds of raw spaghetti noodles would be needed to make 30 cups of cooked noodles.

The correct symbolic expression for a is option C) \(\frac{ma_{1} +F}{m}\)

A symbolic expression, also known as a mathematical expression, is a combination of numbers, variables, and mathematical operators (such as +, -, *, /) that can be evaluated to produce a numerical result.

Symbolic expressions can also contain functions, constants, and mathematical operations like logarithms, trigonometric functions, etc. They can be used to model physical phenomena or to solve mathematical problems.

A logarithmic function is a mathematical function that expresses the power (or exponent) to which a fixed number (the base) must be raised to produce a given value.

It is typically written in the form "logb(x)" where b is the base and x is the value being evaluated. The most common base used is 10 (common logarithm) or e (natural logarithm)

These expressions can be used to represent mathematical concepts, relationships, or equations.

The time he start shopping is 2 : 00 PM

From the question, we have the following parameters that can be used in our computation:

Time spent = 25 minutes

Time he left the store = 2 : 25PM

Using the above as a guide, we have the following:

Time he started = Time he left the store - Time spent

substitute the known values in the above equation, so, we have the following representation

Time he started = 2 : 25PM - 25 minutes

Evaluate

Time he started = 2 : 00 PM

Hence, the time he start shopping is 2 : 00 PM

the figure show, the length between P and T and the length between T and Q, are equal.

so we can say PT=TQ

PT= 3x+2 and TQ=5x-6

so we can replace:

3x+2=5x-6

now we solve

2+6=5x-3x

8=2x

8/2=x=4

and finally, to find PT we replace x by 4

PT=3*4+2=14

So the answer is: PT=14

The values of the coordinates x and y is P ( 6 , 3 )

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( x , y )

Let the second point be Q ( 0 , 0 )

Now , the slope of the line is m₁ = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m₁ = y / x

m₁ = 1/2

So , y/x = 1/2

And , x = 2y

Now , the third point is R ( 7 , 5 )

m₂ = ( 5 - y ) / ( 7 - x )

m₂ = 2

On simplifying , we get

( 5 - y ) / ( 7 - x ) = 2

Multiply by ( 7 - x ) , we get

5 - y = 14 - 2x

Adding 2x and subtracting 5 on both sides , we get

2x - y = 9

Substitute the value of x from m₁ , we get

2 ( 2y ) - y = 0

3y = 9

Divide by 3 on both sides , we get

y = 3

And , the value of x = 6

Hence , the coordinate of the point P is P ( 6 , 3 )

The cost increases $80 per 1 foot increase in side length.

EXPLANATION

If 'x' represents the side length of the fence, its coefficient represents how much each foot of that length costs.

Then 500 is the up-front of the project. If they build a fence with a side length of 5 feet or 500 feet, the cost will be at least $500 - then we'll have to add the cost to each foot of fence.

Using percentages we know that 62% or 62 students out of 100 students prefer biology.

In mathematics, a value or ratio that can be expressed as a fraction of 100 is known as a percentage.

When determining a percentage of a number, we should first divide it by 100 before multiplying the result by 100.

Thus, the proportion refers to a component per 100.

The word percent denotes a percentage of 100. It is represented by the symbol "%."

So, according to the given situation:

34 females enjoy biology

Do boys enjoy biology?

It is 34%≤

Then,

27% favor chemistry

10% favor physics.

The calculation would be:

27 + 11 = 38

100 - 38 = 62

Therefore, using percentages we know that 62% or 62 students out of 100 students prefer biology.

The input of the experiment is the amount of dose of the drug and the output is the growth rate of the cancerous tumor.

Given information:

A medical researcher is using rats to do an experimental test to determine the appropriate dosage for a new cancer drug.

Each rat will be given a different dosage of the drug.

The oncologist will then measure the growth rate of the cancerous tumor.

Now, in the experiment, the oncologist tries to study or calculate the growth rate of a cancerous tumor. So, the output that he/she will get will be the growth rate of the cancerous tumor.

The experiment is done on the rate by giving them a dosage of the drug. The dosage can vary based on the study criterion. So, the amount of dosage of the drug should be the input of the experiment.

Therefore, the input of the experiment is the amount of dose of the drug and the output is the growth rate of the cancerous tumor.

Step-by-step explanation:

There is a proportion you need to write down to solve it but i don’t know how to write it on here!

The length of the third side is 2√34 + 6.

We can use the triangle inequality theorem to solve this problem. According to the theorem, the sum of any two sides of a triangle must be greater than the length of the third side.

Let x be the length of the third side. Then we have:

2√34 + 6 > x

Subtracting 6 from both sides, we get:

2√34 > x - 6

Adding 6 to both sides, we get:

x < 2√34 + 6

Therefore, the length of the third side must be less than 2√34 + 6.

To find the exact length of the third side, we need to check if the triangle inequality is satisfied for an equality. In other words, we need to check if:

2√34 + 6 = x

If this is true, then the given sides can form a triangle.

Simplifying the equation, we get:

x = 2√34 + 6

The exact length is 2√34 + 6 if the triangle inequality is satisfied for an equality.
