Can 7 cm 5 cm and 3 cm form a triangle?

Answer:

Step-by-step explanation:

its closed to 1/2 as 12/24

The values of x = 14 and y = 6.

Triangles that resemble one another but may not be exactly the same size are said to be similar triangles. When two objects have the same shape but different sizes, they can be said to be similar. 

If ΔABC and ΔPQR are two similar triangles

=> AB/PQ = BC/QR = AC/PR

Here we have

ΔFGH and ΔIJH are two similar triangles

FG/IJ = GH/JH = FH/HI  

From the given data,

6/3 = 12/y = x/7    

Take 6/3 = x/7      

Do cross multiplication

=> 3x = 42

=> x = 14  

Take 6/3 = 12/y  

Do cross multiplication

=> 6/3 = 12/y  

=> 6y = 36

=> y = 6  

Therefore,

The values of x = 14 and y = 6.

The distance from the home plate to the 2nd base will be 127.27 ft.

What is Pythagoras theorem?

The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC2 = AB2 + AC2 in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.

Now using the Pythagoras theorem we can find out the length of the other wall

b²=h²-p²

The distance from home plate to the 2nd base will be

b²=h²-p²

h² = b²+p²

h² = 2*90²

h² = 2*90²

h² = 2*8100

h² = 16200

h = 127.27

Answer:

The expression p + 0.08p can be interpreted as "p plus 8% of p". Mathematically, this expression is equal to 1.08p, which is the same as saying "p multiplied by 1.08".

The given number 0.02 can be written in exponential form as [tex]2 \times 10^{-2}[/tex] , because to express small number in exponential form power of 10 notation is used .

To write the number 0.02 to exponential form ,

the first step is to move the decimal point to right until it is after the first non zero digit.

In this number we move the decimal point to move two spaces to right.

So , the number becomes ; [tex]\frac{2}{100}[/tex] ;

Now , we multiply the number 2 we created by 10 having exponent of -2. we know that , Whenever decimal point moves to right, the exponent of 10 will be a negative exponent.

The number after the decimal point is always equal number of spaces  decimal point moves.

So , the final exponential form of 0.02 is [tex]2 \times 10^{-2}[/tex] .

Answer:

325 adults and 612 students entered the school play

Step-by-step explanation:

1st equation: x is the number of adults and y the number of students.

2nd equation: Students times what they payed + adults times what they payed:

1st:          x + y = 937

2nd:       2x + 0.75y = 1109

x = 937 - y

Now let's replace x for (937 - y) in the 2nd equation, to find out the value of y:
2(937 - y) + 0.75y = 1109

1874 - 2y + 0.75y = 1109

1874 - 1.25y = 1109

-1.25y = 1109 - 1874

-1.25y = -765 (multiply -1)

1.25y = 765

y = 765 / 1.25

y = 612

Now that we found the y value, let's replace it in the 1st equation to find out the value of x:

x + 612 = 937

x = 937 - 612

x =  325

If you want to double check it, you can replace both in the 2nd equation, to make sure:
2 * 325 + 0.75 * 612 = 1109

650 + 459 = 1109  (checked)

The formula for finding the area of a triangle with an unknown height is: Area = (Base * Height) / 2. This formula uses the base length of the triangle, multiplied by the height of the triangle, then divided by 2. To use this formula, start by determining the base length of the triangle. This is the length of any one side of the triangle. Once the base is determined, use the formula to calculate the area. In the formula, the base is multiplied by the height of the triangle. Since the height is unknown, use the Pythagorean Theorem to calculate it. The Pythagorean Theorem states that the square of the hypotenuse (the longest side of the triangle) is equal to the sum of the squares of the other two sides. Once the hypotenuse is known, the height can be found by using the formula (Height = Hypotenuse - Base) / 2.

You can conclude that it took you less time on Tuesday to run to and from the playground than it did on Monday.

Distance is defined as the product of speed and time.

To compare the times it took to go to and from the playground each day, you need to calculate the total time for each day.

On Monday, it took 22 minutes to run to the playground and 25 minutes to run back home, for a total time of 47 minutes.

On Tuesday, you ran the entire 4 1/2 miles at a constant speed of 6 1/4 miles per hour, so you can use the formula:

distance / speed = time.

In this case, 4.5 miles / 6.25 mph = 0.72 hours or 43.2 minutes.

In mathematics, a transformation refers to a function or a mapping that takes an input and produces an output. The input and output can be geometric shapes, vectors, or functions, and the transformation can change their position, size, or shape. Examples of transformations include translation, rotation, scaling, and reflection. In physics and engineering, transformation also refer to mathematical operations used to change a system's variables from one set of coordinates to another set of coordinates.

Scaling refers to the process of enlarging or reducing an object in size, either uniformly or non-uniformly. In mathematics, scaling is often represented by a scaling factor, which is a number used to multiply the coordinates of the object. Scaling can be applied to geometric shapes, vectors, and functions, and it can be done in one or multiple dimensions. Uniform scaling means that the object is scaled by the same factor in all dimensions. Non-uniform scaling means that the object is scaled by different factors in different dimensions.

From the linear function that is represented by the table, we can conclude that the slope is -2, and the y-intercept is 12.

The linear function is an equation for a line that can be written by finding the slope between two points on that line, then finding the y-intercept by using the slope-intercept equation: y=mx+b, where b represents the y value of the y-intercept point.

Now we take a look at the following data:

X     Y

–3   18

0    12

3     6

6     0

We want to know the slope by picking two out of four given points, let's say we pick the first two points:

y - y₀ = m (x - x₀)

(18 - 12) = m (-3 - 0)

6 = m * -3

m = 6 / -3

m = -2

Thus the slope is -2.

Now we substitute the slope value to one of the points, let's say we pick the first point:

(x₀, y₀) = (-3, 18)

y - y₀ = m (x - x₀)

y - 18 = -2 (x - (-3))

y = -2x - 6 + 18

y = -2x + 12
