Answer:

Answer:

x

Step-by-step explanation:

[tex]g^2 (x)=\frac{2\left(\frac{2x}{x-2} \right)}{\frac{2x}{x-2}-2} \\ \\ =\frac{4x}{2x-2(x-2)} \\ \\ =\frac{4x}{4} \\ \\ =x[/tex]

In the experiment, the solubility of B is high than the solubility of A.

This is because the mass of undissolved substance of substance A is more than Substance B at every temperature.

The amount of a substance that dissolves in a specific amount of solvent is known as its solubility. Higher solubility results from more solute dissolution, while lower solubility results from less solute dissolution.

Regarding the observations made, at any temperature, the mass of the undissolved material of substance A is greater than that of substance B. This suggests that less solute dissolves in the amount of solvent provided.

Therefore, because of this, substance B is more soluble than substance A.

The answer is 11500000 Square Meters

Answer:

11,500,000

Step-by-step explanation:

To convert 1150 hectares to square meters, we need to multiply it by 10,000. Therefore, 1150 hectares is equal to 11,500,000 square meters. It is important to note that one hectare is equal to 10,000 square meters. So, 1150 hectares is equivalent to 11,500,000 square meters or 11,500,000 square meters. This conversion is useful when measuring large areas of land, such as agricultural fields, forests, and parks.

In mathematics and statistics, the arithmetic mean or arithmetic average, or just the mean or the average, is the sum of a collection of numbers divided by the count of numbers in the collection

An arithmetic average is the sum of a series of numbers divided by the count of that series of numbers. If you were asked to find the class (arithmetic) average of test scores, you would simply add up all the test scores of the students and then divide that sum by the number of students.

The arithmetic mean or mean is the simplest way to calculate the average for the given set of numbers. It is classified into two different types, namely simple arithmetic mean and weighted arithmetic mean.

Answer:

old price was $170; new price is $159.12

Step-by-step explanation:

1) Formula given:

Selling price = original cost + mark up value

2) Old price = original cost + 25% (original cost)

Old price = $136 + 35% ($136) = $136 + 0.25×$136 = $136 + 34 = $170

3) New price = original cost + 17% (original cost)

= $136 + 17% ($136) = $136 + 0.17×$136 = $136 + $23.12 = $159.12

The Expanded form of 3×1=3 is 3

The Expanded form of 250 is 200+50+0

Expanded form is nothing more than a method for rewriting a number such that the digit values are included. A place value exists for each number. It calculates that digit's value based on where it is in the number. As we move from left to right in a number, a digit's value rises. In comparison to the digits on the right, the ones on the left have a lower place value. The position of the number is used to calculate each number's value. We can comprehend the place value notations if we read them from right to left.

250=200(hundreds place)+50(tens place)+0(ones place)

Therefore, the Expanded form of 250 is 200+50+0.

In Mathematics, there are different types of transformation and these include the following:

A translation can be defined as a type of transformation which moves every point of the object in the same direction, as well as for the same distance.

By using the given translation rule: (x, y) → (x + 1, y - 1), we have:

N(-1, -1) → N'(-1 + 1, -1 - 1) = N'(0, -2).

F(3, 3) → F'(3 + 1, 3 - 1) = F'(4, 2).

Q(3, -1) → Q'(3 + 1, -1 - 1) = Q'(4, -2).

The probability of getting an offspring pea that is green is 0.967 and the value is not close to 3/4.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

It is given that:

In a genetics experiment on peas, one sample of offspring contained 383 green peas and 13 yellow peas.

The probability of getting an offspring pea that is green = 383/(383+13)

= 383/396

= 0.967

= 0.75

Thus, the probability of getting an offspring pea that is green is 0.967 and the value is not close to 3/4.

The coordinates of the point 7/10 of the way from A to B is (2.4, 4.2)

On the coordinate plane, we have the following coordinates

A = (-3, -8)

B = (11, 6)

The point 7/10 can be represented using the following ratio

m : n = 7 : 3

The coordinates of the point 7/10 of the way from A to B is calculated as

Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)

This gives

Point = 1/(7 + 3) * (3 * 11 + 3 * -3, 11 * 6 + 3 * -8)

Evaluate

Point = 1/10 * (24, 42)

This gives

Point = (2.4, 4.2)

Hence, the coordinates of the point 7/10 of the way from A to B is (2.4, 4.2)

Answer:

x < 12

Step-by-step explanation:

So 8 times the sum of a number and 26 is less than 304. To find the number, lets write a equation where the "number" is x.
8 times the sum of a number and 26 can be written as 8 * x+26, however since the sum of x and 26 are being multiplied, we write this as 8(x+26). Since 8 times the sum of a number and 26 is less than 304, we set 8(x+26) to < 304. This gives us our equation:

8(x+26) < 304

Lets start to solve for x by dividing by 8, giving us:

x+26 < 38

Now lets isolate x by subtracting 26 from both sides, which gives us our answer:

x < 12

So x is less than 12.

Yes, they are equivalent, because one is just a reduced version of the other. Since they are equally balanced when reduced, they are equivalent ratios.

Answer:

Yes, It is equivalent.

Step-by-step explanation:

To convert [tex]\frac{10}{16}[/tex] , so the denominator is 16, multiply the numerator and denominator by 1.

[tex]\frac{5*2}{8*2}[/tex] vs [tex]\frac{10*1}{16*1}[/tex]

The speed of the commuter train in kilometre per hour is 30.59 kilometres per hour

The given parameters are

Distance = 26 kilometres

Time = 51 minutes

Convert the number of minutes to hour

So, we have

Time = 51/60 hour

The speed of the commuter train in kilometre per hour is calculated as

Speed = Distance/Time

So, we have

Speed = 26 kilometres/(51/60 hour)

Evaluate the quotient

Speed = 30.59 kilometres per hour

To find the LCD of (5/6, 3/8) we need to find the Least Common Multiple (LCM), which in this case is (6, 8). So we want to find the values of the numerical part of each term. We need to select the largest one, which in this case is 8

Then multiply them together to get the current total. In this case, the current total is 48

Current Total =  48

Multiply the numeric part of the denominators together.

Current Total = 8 + 8 = 16

Again, multiply the numeric part of the denominators together.

Current Total = 16 + 8 = 24

Check each value in the numerical part of each term against the current total. Since the current total is evenly divisible, return it. That is the least common denominator of the numerical part of the fraction.

So the Lowest Common Denominator (LCD) is 24
