Find the value of x + y for x = 75.9 and y = 2.65.

because the square root of 4 is 2 and the square root of 9 is 3 which means 2x3=6 and 9x4=36 and the square root of 36 is 6 because 6x6=36

The decimal expansion of 1/9 is 0.1111..., which continues indefinitely. This is achieved by dividing the numerator (1) by the denominator (9). The decimal expansion of a fraction is the expression of that fraction in base 10 notation.

The decimal expansion of the fraction 1/9 is 0.1111.... This is achieved by dividing the numerator (1) by the denominator (9). The process of long division would show you that 9 doesn't go into 1, so you add a decimal point and a zero, making the dividend 10. 9 goes into 10 once, so you put a 1 in the quotient above the line. This process repeats itself due to the nature of the divisor 9 and the decimal 0.1111... continues indefinitely.

It's important to note that the decimal expansion of a fraction is an expression of that fraction in base 10 notation. In other words, it is the fraction expressed as a decimal.

For some numbers, this can be a finite number of digits long, and for others, like 1/9, it can be infinitely repeating.

Remark

You have to read this carefully to know what way to write it.

One way you could write it would be

20 * x = 18 where x is  the fraction. Now all you need do is divide.

Divide both sides by 20

20/20 * x = 18/20

[tex]\text{x = } \dfrac{18}{20}[/tex]

But you should reduce this fraction. The way to do that is to factor 18 and 20 into primes.

18: 2 * 3 * 3

20: 2 * 2 *5

Cancel out the Highest common factor or 2.

You are left with

[tex]\text{x = } \dfrac{18}{20} =\dfrac{2*3*3}{2*2*5}=\dfrac{3*3}{2*5} = \dfrac{9}{10}[/tex] <<<< Answer

★ What fraction of 20 is 18?

In questions like these, when you see the word "of", it is usually used for the denominator. In your question, it says "of 20". That means the denominator will be 20.

Here is your current fraction:

[tex]\frac{x}{20}[/tex]

After that phrase, it says "is 18". The word "of" is used for the numerator. That means the numerator is 18.

Here is your fraction:

[tex]\frac{18}{20}[/tex]

You have your complete fraction, but it can be simplified. Both numbers are even(numbers that end with 2, 4, 6, 8, or 0) and every even number is divisible by 2. You can just divide both numbers by 2.

[tex]\frac{18 \div 2}{20 \div 2} = \frac{9}{10}[/tex]

You have your simplified fraction, which is [tex]\frac{9}{10}[/tex], and it cannot be simplified any further.

Your answer is [tex]\frac{18}{20}[/tex] which becomes [tex]\frac{9}{10}[/tex] when simplified.

[tex]y = \frac{1}{3}x - 1[/tex]

Step-by-step explanation:

Let the gradient be calculated as follows:

slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

         = [tex]\frac{-7-(-3)}{6-(-6)}\\ = -\frac{1}{3}[/tex]

to find the equation passing through the point we calculate as follows:

[tex]- 3= \frac{1}{3} (-6) + b\\ -1 = b[/tex]

Therefore, the equation of the line is:

[tex]y = \frac{1}{3}x - 1[/tex]

An equation of this graphed line in slope-intercept form is [tex]y=-\frac{1}{3} x-5[/tex].

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (-7 - (-3))/(6 - (-6))

Slope (m) = -1/3.

At data point (6, -7) and a slope of -1/3, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

[tex]y-(-7)=-\frac{1}{3} (x-6)\\\\y+7=-\frac{1}{3} (x-6)\\\\y=-\frac{1}{3} x-5[/tex]

Hello...

What creates the convection current inside Earth?

A. Rising and sinking of material

Answer: A. Rising and sinking of material.

Step-by-step explanation:

Convection currents are caused by the cooling of material as it rises up, which leads to the same material to sink. This material then warms as it sinks to rise again. This is why we call them convection currents. Because they both rise, and sink, in a circular motion we call the convection current.

Hey there!

Your answer is no.

I'll give an example to prove this wrong for you.

We have one rectangle with the dimensions of 2 x 6 units and another rectangle with dimentions of 4 x 4 units.

The perimiter of the first one is 16 because the four sides added up is 16: 2 + 2 + 6 + 6 = 16

The perimiter of the second is also 16. 4 + 4 + 4 + 4 = 16

So, they both have the same perimeter, but they are not congruent because their sides are different lengths.

Given

 One warehouse had 185 tons of coal, another one had 237 tons

The first warehouse delivered 15 tons of coal to its clients daily, the second one delivered 18 tons of coal to its clients daily.

Find out in how many days will the second warehouse have 1.5 times more coal than the first one.

To proof

Let us assume that the number of days of delivered the coal = x

Take two cases

First case

As given in the question

One warehouse had  coal = 185 tons

The first warehouse delivered 15 tons of coal to its clients daily

(As first warehouse delivered 15 tons of coal to its clients daily than the total amount of coal decrease daily as days increase)

Than the equation becomes for first warehouse

= ( 185 - 15x)

( this equation represent the amount of coal left after x days)

Second case

second warehouse had  coal = 237 tons

the second one delivered 18 tons of coal to its clients daily.

(As first warehouse delivered 18 tons of coal to its clients daily than the total amount of coal decrease daily as days increase)

Than the equation becomes for the second warehouse

= ( 237 - 18x)

( this equation represent the amount of coal left after x days)

As given in the question

the second warehouse have 1.5 times more coal than the first one

Thus

( 237 -18x ) = 1.5× ( 185 - 15x)

237 - 18x = 277.5 - 22.5x

22.5x - 18x = 277.5 - 237

4.5x = 40.5

x = 9

Therefore  the second warehouse have 1.5 times more coal than the first one in 9 days.

Hence proved

Patrick initially has 600 meters of yarn. After using some to make a hat, he only has 351.1 meters of yarn left, which is not enough to make a scarf that requires 354.03 meters.

To answer this question, we have to perform a subtraction operation on the total lengths of yarn. Initially, Patrick has a 600-meter skein of yarn. After making a hat, he uses 248.9 meters of yarn. To find out how much yarn is left, we subtract the amount used from the total: 600 - 248.9 = 351.1 meters. You then need to check if 351.1 meters are enough to make a scarf that consumes 354.03 meters of yarn. In this case, we can see that Patrick does not have enough yarn left to make the scarf because 351.1 meters is less than 354.03 meters.

Step-by-step explanation:

There are a total of 18+6+32 = 56 spectators.

Out of this total number, 18 cheered for Luca; this gives us the ratio

18/56.

Both of these are even numbers.  This means we can divide both by 2:

(18÷2)/(56÷2) = 9/28

Answer:

75

Step-by-step explanation:

Number of foul shots made by the girl first time = 12

Number of shots missed by the girl first time = 8

Total number of shots played first time = 12 + 8 = 20

Let the number of foul shots made by the girl second time be x

The total number of shots played by the girl second time = 125

Let's set up a proportion,

[tex]\frac{Number of foul shots made by the girl first time}{Total number of shots played first time}[/tex] = [tex]\frac{number of foul shots made by the girl second time}{total number of shots played by the girl second time}[/tex]

=> [tex]\frac{12}{20} = \frac{x}{125}[/tex]

Flip the sides of the equation

[tex]\frac{x}{125} = \frac{12}{20}[/tex]

Multiplying both the sides by 125

[tex]\frac{x}{125}*125 = \frac{12}{20}*125[/tex]

Cancelling out the 125's on the top and bottom from the left side

x = [tex]\frac{12}{20}*125[/tex]

=> x =  [tex]\frac{1500}{20}[/tex]

=> x = 75

Number of foul shots made by the girl if she played 125 foul shots = 75

To find out how many shots the girl made, set up a proportion using the ratio of shots made to shots missed. The girl made 187 shots.

To find out how many shots the girl made, we can set up a proportion using the ratio of shots made to shots missed. The ratio is 12:8. Let's assume the number of shots made is x. We can create the proportion: 12/8 = x/125. Cross-multiplying gives us 8x = 12 * 125. Solving for x gives us x = (12 * 125) / 8. Evaluating this expression gives us x = 187.5. Since we can't have a fraction of a shot, we round down to the nearest whole number. Therefore, the girl made 187 shots.

Your answer is A. The sum of x and y is a rational number .

Answer:

A) The sum of x and y is a rational number.

Step-by-step explanation:

We will first prove that the given values of x and y are rational and then we will prove the fact that the sum of two rational numbers is a rational number.

A rational number is a number which is in the form [tex]\frac{p}{q}[/tex], where p and q are integers and q ≠ 0.

We can write - 5 as [tex]\frac{-5}{1}[/tex] and clearly 1 ≠ 0.

So, x = -5 is a rational number.

Similarly, y = -4 is also a rational number.

For the second part of the proof, consider any two rational numbers [tex]\frac{p}{q}[/tex] and [tex]\frac{r}{s}[/tex].

Now,

[tex]\frac{p}{q} +\frac{r}{s} =\frac{ps+rq}{qs}[/tex]

Since p, q, r and s are integers, ps + rq is also an integer.

Moreover, since q ≠ 0 and s ≠ 0, qs ≠ 0.

Therefore, [tex]\frac{ps+rq}{qs}[/tex] is also a rational number.

Hence, sum of two rational numbers is also a rational number.

Since x = -5 and y = -4 are rational numbers, x + y = (-5) + (-4) = -9 is also a rational number.

Answer:

the two integers are 17 and 18

Step-by-step explanation:

Let x represent the smaller integer. Then x+1 is the larger. The problem statement tells us

... 2 × larger = -15 + 3 × smaller

... 2(x+1) = -15 + 3x . . . substitute variable expressions for 'larger' and 'smaller'

... 2x +2 = 3x -15 . . . . . eliminate parentheses

... 17 = x . . . . . . . . . . . . .add 15-2x

The smaller integer is 17, so the larger is 18.

_____

Check

2×18 = 36 = 3×17 -15 = 51-15

Let's take the first number as 'x' ( This would be the smaller number )

Let's take the second number as 'x+1' ( This would be the larger number )

I have taken x and x+1 because both these numbers are consecutive.

Twice the larger number :-

... 2 ( x + 1 )

... 2x + 2

15 less than thrice the smaller number :-

... 3x - 15

The question states that these both values are equal. Hence,

... 2x + 2 = 3x - 15

... 2 + 15 = 3x - 2x

... 17 = x

The value of 'x' is 17

( The smaller number is 17 )

Larger number :-

... x + 1

... 17 + 1

... 18

Hence, the numbers are 17 and 18.
