He played a total of 20 games with 2 lost,4 win and 14 draw matches.

Given that

Yashwant participated in a chess league,

Outcomes of the chess game can be win or loss or draw.

And Yashwant has lost 10% of the games he played.

Let us think that Yashwant has played 'x' number of games in this chess league.

That means Yashwant has lost [tex]\frac{x}{10}[/tex] number if games in the chess league.

And they also given that he just lost total of 2 games only;

That implies

[tex]\frac{x}{10} =2\\x=20[/tex];

That gives us value of x, which is the total number of games played by Yashwant in chess league.

They gave that number of wins is double the number of losses;

That gives us 2×2(Number of games Yashwant lost)=4 is number of games Yashwant won in the chess league.

As Total=Wins+ Loss+ Draw;

[tex]20=4+2+Draw\\Draw=14[/tex]

That means Yashwant has won 4, lost 2, Drawn 14 games in the league.

He played a total of 20 games with 2 lost,4 win and 14 draw matches.

the perimeter of a triangle is 49 feet. The triangle's one side is seven feet shorter than its other. the length of each side , Second side: 16 feet, First side: 9 feet,Third side: 12 feet

To find the length of each side of the triangle, we need to start by looking at the perimeter, which is 49 feet.

Perimeter = 49 feet

Second side = 49 - 4 = 45 feet

First side = 45 - 7 = 38 feet

Third side = 45 + 4 = 49 feet

We know that the third side is 4 feet shorter than the second side, so we can subtract 4 feet from the perimeter to find the length of the second side, which is 16 feet. Then, we know that the first side is 7 feet shorter than the second side, so if we subtract 7 feet from the second side we can find the length of the first side, which is 9 feet. Finally, to find the length of the third side, we add 4 feet to the second side, which gives us 12 feet. Therefore, the length of each side of the triangle is 9 feet, 16 feet, and 12 feet.

Answer:

The answer is the standard form equation for a hyperbola with center at the origin, vertices at (1, 0) and (-1, 0), and foci at (5, 0) and (-5, 0), which is:

x^2 - \frac{y^2}{5} = 1

This equation describes the shape of the hyperbola and allows you to determine the location and size of the hyperbola on a coordinate plane.

Step-by-step explanation:

The standard form equation for a hyperbola with center at the origin, vertices at (1, 0) and (-1, 0), and foci at (5, 0) and (-5, 0) is given by:

$$\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1$$

where $a$ and $b$ are the lengths of the semi-major and semi-minor axes, respectively. In this case, the distance between the vertices is 2, so the semi-major axis is 1 and the semi-minor axis is $\sqrt{5}$. Therefore, the equation of the hyperbola is:

$$\frac{x^2}{1^2} - \frac{y^2}{\sqrt{5}^2} = 1$$

which simplifies to:

x^2 - \frac{y^2}{5} = 1

The answer is yes, it is possible to have the sum of square roots equal the square root of the sum of the radicands.

A square root of a number is a value that, when multiplied by itself, gives the number.

Given that, is it possible √a+√b = √a+b

Yes, it is possible to have the sum of square roots equal the square root of the sum of the radicands.

If either a or b equals zero, then the sums would be the same.

Since the square root of 0 is ±0, adding it to a given radical would not change the radical. Also, adding zero to the radicand would not change its value.

Hence, it is possible to have the sum of square roots equal the square root of the sum of the radicands.

A t-test cannot cover more than one group. This has to do with the underlying method used to calculate the test value.

Explain about t-test?

The t-test is designed to compare the means of two populations based on the means of the two samples. (any sample from either population).

The most important observation is that the t-test computes the difference between two sample means.

If you have trouble understanding 'variance', you can use the word standard deviation from the previous text to get your points.

In other words, there is more than one difference between the groups, but we want one measure of Total Difference Between Groups. The t-test cannot do that.

So the procedure for groups of three or more is: Run ANOVA first. As a second step, if you have reason to believe that differences exist (based on this test), you can use the t-test to determine where those differences lie.

Let Q be the number of quarters and N be the number of nickels that Hugo has. We are given that Hugo has 4 * N quarters and that the total number of quarters and nickels is worth 840 cents. Since each quarter is worth 25 cents and each nickel is worth 5 cents, the total number of quarters is worth 25 * Q cents and the total number of nickels is worth 5 * N cents. Therefore, the total number of quarters and nickels is worth 25 * Q + 5 * N cents. Since the total number of quarters and nickels is worth 840 cents, we can set up the following equation to represent this information:

25 * Q + 5 * N = 840

We are also given that Hugo has 4 * N quarters, so we can set up the following equation to represent this information:

Q = 4 * N

We can solve this system of equations to find the number of quarters and nickels that Hugo has. Substituting the value of Q in the second equation into the first equation, we get the following:

25 * (4 * N) + 5 * N = 840

Distributing the 25 on the left side of the equation, we get the following:

100 * N + 5 * N = 840

Combining like terms, we get the following:

105 * N = 840

Dividing both sides of the equation by 105, we get the following:

N = 8

Substituting the value of N into the second equation, we get the following:

Q = 4 * 8

Solving for Q, we get the following:

Q = 32

Therefore, Hugo has 8 nickels and 32 quarters.

Answer:

32 quarters

8 nickels

Step-by-step explanation:

Information:

Define the variables:

If Hugo has 4 times as many quarters as nickels:

[tex]\implies x=4y[/tex]

If the combined value of quarters and nickels is 840 cents:

[tex]\implies 25x+5y=840[/tex]

Substitute the first equation into the second equation and solve for y:

[tex]\implies 25(4y)+5y=840[/tex]

[tex]\implies100y+5y=840[/tex]

[tex]\implies 105y=840[/tex]

[tex]\implies y=8[/tex]

Substitute the found value of y into the first equation and solve for x:

[tex]\implies x=4(8)[/tex]

[tex]\implies x=32[/tex]

Therefore, Hugo has:

Answer:

y = -9x + 31

Step-by-step explanation:

We can find the slope of the second line using the formula

[tex]m_{2}=-\frac{1}{m_{1} }[/tex], where m2 is the slope of the second line and m1 is the slope of the first.

Thus, since 1/9 is the slope of the first line, we have

[tex]m_{2}=-\frac{1}{(1/9)} \\m_{2}=-9[/tex]

Since the slope intercept form is y = mx + b, where b is the y-intercept, we need to it in the second line by plugging in (3, 4) for x and y and -9 for m:

[tex]4=-9(3)+b\\4=-27+b\\31=b[/tex]

Answer:

  -25/(12π) ft/min ≈ -0.663 ft/min

Step-by-step explanation:

You want the rate of change of height of the salt in a cone with height 5 ft and diameter 4 ft, filled 3 ft up from the vertex, and decreasing in volume at the rate of 3 cubic feet per minute.

The rate of change of height is the rate of change of volume, divided by the surface area.

The given cone dimensions tell you the radius is 2/5 of the height of the cone, so the radius of the surface when it is filled to a depth of 3 ft is ...

  r = (2/5)(3 ft) = 1.2 ft

The area of the surface is the area of a circle with this radius:

  A = πr² = π(1.2 ft)² = 1.44π ft²

Then the rate of change of height is ...

  h' = V'/A

  h' = (-3 ft³/min)/(1.44π ft²) = -25/(12π) ft/min ≈ -0.663 ft/min

The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.

Comparing two integers that each stand for a component of a whole results in a proportion. In essence, a percentage declares that two fractions are equal, regardless of the difference in amount. For instance, the ratio of half of 10 marbles to half of 50 marbles is 10.

a) The total amount of money they share is $70

b) The amount Moira gets is $21, while the amount Non gets is 3 : 7

A ratio is a quantitative expression that specifies the number of times a value is contained within another value.

The ratio by which Moira and Non share the money = 3 : 7

The amount Non gets = 28 + The amount Moira gets

Let x represent the amount Moira gets, therefore;

The amount Non gets = 28 + x

The specified ratio indicates;

[tex]\dfrac{x}{28 + x} = \dfrac{3}{7}[/tex]

7·x = 3 × (28 + x)

7·x = 84 + 3·x

7·x - 3·x = 84

4·x = 84

x = 84 ÷ 4 = 21

x = 21

The total amount of money = The amount Moira gets + The amount Non gets

Therefore; The total amount of money = x + 28 + x = 2·x + 28

2·x + 28 = 2 × 21 + 28 = 70
