1. 8*14= 112

2. 12*6= 72

3. 112- 72= 40

Answer:

-1/1

Step-by-step explanation:

The slope of a line is always the rise over run where rise is up or down(y axis) and the run is side to side(x-axis). Then, if the line is going up, your answer will be negative. So, using the points given, you can tell that the line is moving 2 units down while also moving 2 units to the left. Another way to calculate this is y2-y1 over(/) x2-x1, the y equals your y coordinates, x equals your x coordinants,d the 1 and 2 represent which points. Whichever point you use, you have to use the same coordinants fr the same value. For example, if you took the points (-2,0) and (0,-2) and you used (0,-2) as your second value, you can enter those into the formula.

(-2)-(0) / (0)-(-2) = -2 / 2

the denominater is a possitive two because, when you subtract a negative number, that number becomes positive and you now add it due to the distributive property. 0-(1)(-2) = -2 x -1 = 2

Answer:

The result of this dilation is an enlargement. The scale factor is 3.

Step-by-step explanation:

The original figure has coordinates (0,0), (1,0), (2,0), (2,1), and (1,1). The dilated figure has coordinates (0,0), (3,0), (6,0), (6,3), and (3,3). Notice that the distances between corresponding points in the original and dilated figures are all multiples of 3. This means that the dilation has a scale factor of 3.

In general, a dilation is an enlargement if the scale factor is greater than 1, a reduction if the scale factor is less than 1, and a congruent image if the scale factor is equal to 1.

Answer:4/5

Step-by-step explanation:

80% means 80/100 in fraction. We have to simplify the fraction by 80÷20 and 100÷20 = 4/5

So the answer is 4/5.

Answer:

Step-by-step 80 percent is 80\100 so

For the first one (4\5) 5x20=100 and 4x20=80 which is 80\100

so it should be 4\5

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Answer:

Base = 18  Height = 4 (this is an example)

Step-by-step explanation:

Given that the triangle has an area of 36 square feet, and that the triangle area formula is A=1/2bh (b being the base, and h being the height), we can fill in the formula to get the dimensions.

To find the given numbers, we need to find what numbers are divisible to by 2 to get 36. For instance using the formula A=1/2bh, we can plug in the factors that make up 72 (if you divided it by two you will get 36). Example of this is 18x4, so we can plug it into the equation to prove it through factor trees (feel free to reach out if you have a question about those). Plugging 18 and 4 will give 18x4 divided by 2 = 36.

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Step-by-step explanation:because they just look alike

Step-by-step explanation:

1. Find the GCD (or HCF) of numerator and denominator

GCD of 423 and 16 is 1.

2. Divide both the numerator and denominator by the GCD

423 ÷ 1= 323

16 ÷ 1=16

3. Reduced fraction:

423

16

Therefore, 423/16 simplified to lowest terms is 423/16.

Answer: 423/16

Step-by-step explanation:

To be able to simplify 423/16, we need to find their greatest common factor (GCF). This is much easier to do using the smaller number, as it has less factors most of the time.

The factors of 16 are: 1, 2, 4, 8, 16.

If 423 shares one of these factors, we can simplify 423/16.

Since 2, 4, 8, and 16 are even numbers and 423 is odd, we already know that those are not factors of 423.

So, the only factor of 16 left that 423 shares is 1. If you divide 423/1 and 16/1, the fraction still is 423/16. This means that 423/16 is already in its simplest form.

If you want to find the decimal form of 423/16, it is 26.4375. 16 x 26 = 416. 416 + 16 = 432, which is greater than 423.
This means that 16 goes into 423 twenty-six times before it cannot fully go into it anymore.

No the given relation is not a function because for one input we are getting two different values of output which negates the definition of the function.

A relation is said to be a function when each and every element of domain has a unique and distinct image means we will get only one output per input.So

Hence the given relation is not a function.

The given relation is not a function because for each input (x-value), there is not exactly one output (y-value).

In a function, each input (x-value) should have only one corresponding output (y-value). However, in this relation, the input value of 1 has two different output values: -2 and 3. Therefore, it violates the definition of a function.

To illustrate this, let's look at the points (-2, 0), (1, -2), and (1, 3). The x-value of 1 appears twice in the relation, but it has two different y-values associated with it. This means that for the input value of 1, there is not exactly one output value, which is why the given relation is not a function.

In conclusion, the relation is not a function because for each input there is not exactly one output.

Answer:

A.  x  ≥ 4

Step-by-step explanation:

When circle closed we use  ≥ to show an equal quantity stop

When circle closed at the lowest inequality we show a less than or equal to inequality ≤

When circle open we just apply the same > to show a larger quantity stop

when circle open we just apply the lowest inequality <

so < and  ≤  is lowest numbers compared.

and  > and ≥ is higher numbers compared.

Junior says the product of 25 x 10 is 250.  Junior's answer is correct.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given problem is;

25 × 10 = ?

Since, 1 × 10 = 10

2 × 10 = 20,

3 × 10 = 30,

4 × 10 = 40

When we observe this sequence,

It is found that, when we multiply a number by 10 we obtain the resultant number by putting 0 in the ones place of the given number.

That is,

25 × 10 = 250

Therefore, Junior's answer is correct.
