Gabrielle is 10 years younger than Mikhail. The sum of their ages is 74. What is Mikhail's age?

The inverse function of the given is [tex]y^-1[/tex]= [tex]\frac{x}{2}[/tex]-4 .

What is inverse function?

The domain of the original function becomes the range of the inverse function, and the range of the given function becomes the domain of the inverse function. The inverse function is denoted by the notation f-1 in relation to the original function f. Swapping (x, y) with (y, x) with reference to the line y = x yields the graph of the inverse function. Only when f is both a one-one and an onto function does it have an inverse, indicated by the symbol f-1. Keep in mind that f-1 is NOT f's inverse. The domain value of x is given by combining the function f and the reciprocal function f-1.

Here the given function is,

=> y = 2x+8

Now interchange x and y then

=> x=2y+8

Now simplify the expression with respect to y then,

=> x-8=2y

=> y = [tex]\frac{x}{2}[/tex]-4

=>[tex]y^-1[/tex]= [tex]\frac{x}{2}[/tex]-4

Hence inverse function is [tex]y^-1[/tex]= [tex]\frac{x}{2}[/tex]-4 .

Yes line TV is also parallel to line QS according to transverse property

According to the transitive property, all the quantities are equal to each other if two quantities are equal to the third quantity.

When the term equal is replace by parallel it suits the case at hand hence transitive property of parallel lines is introduced

When attempting to demonstrate that several parallel lines have congruent properties, the transitive property of parallel lines can be used to create a link between numerous equal quantities.

Therefore, it can be interpreted as: if line TV || line ZX and line ZX || line QS then line TV || line ZX

The radius of the basket ball having volume 452.1 cubic inches is 4.76 inches.

What is the volume?

Volume is the 3 dimentional occupied space by any object. It is measured in SI units [tex]\textnormal{m}^3[/tex] and other derived units like [tex]\textnormal{in}^3[/tex].

All properties of a spherical shape is defined by its radius. The shape of a basketball is spherical hence, the formula of the volume is given by the followin expression:

[tex]V=\frac{4}{3}\pi r^3[/tex]

Here, V is the volume of the basket ball and r is the radius of the basket ball.

Rearrange the above equation for [tex]r[/tex].

[tex]3V=4\pi r^3\\\frac{3V}{4\pi}= r^3[/tex]

[tex]r=[\frac{3V}{4\pi}]^{1/3}[/tex]

Substitute values.

[tex]V=[\frac{3(452.1 \ \textnormal{cubic inches})}{4\pi}]^{1/3}\\=4.76 \ \text{inches}[/tex]

The measures of those two angles are 35° and 50°.

It's important to note that the sum of angles on a quadrilateral is 360°. In this case, two angles of a quadrilateral measure 260° and 15º.

The remaining angles will be:

= 360° - (260° + 15°)

= 85°

Since the other two angles are in a ratio of 7:10, the measure will be:

= 7 / (7 + 10) × 85°

= 7/15 × 85°

= 35°

Also, 10/17 × 85°

Total cost  to tile the kitchen =$273.78

Let the width of kitchen = w

The length of the kitchen is nine feet shorter than three times its width, w  = 3 w-9    equation-----1

The perimeter of the kitchen is six times the width = 6 w

= 2(length+width) =6 w    equation----2

from equation 1 and 2

= 2(3 w-9+w) = 6 w

= 6 w-18+2 w = 6 w

   2 w = 18

   w = 9

Length = 3 w-9

length  = 3×9-9

length  = 18

Area of kitchen = length×width

                          = 18×9

                          = 162 square foot

Cost of tiles per square = $1.69

Total cost  to tile the kitchen = Area of kitchen × cost of tiles per square

                                                = 162×$1.69

                                                =$273.78

If the tiles cost $1.69 a square foot, the total cost to the tiles of the kitchen is $273.28.

According to the question:

Let the width be = x

Then, the length of the rectangular kitchen is L = 3x - 9

The perimeter is = 6x

It is given that the cost of the tile = $1.69 a square foot.

Then the total costs of tiles the kitchen is :

The Perimeter of the rectangle =  2(L + b)

The Perimeter of the rectangle =  2(3x - 9 + x)

The Perimeter of the rectangle =  2(4x-9)

We know that, according to the question,

the perimeter of the kitchen is six times the width = perimeter of rectangle

⇒ 6x = 8x - 18

⇒ - 2x = - 18

⇒ x = 18/2

⇒ x = 9

Thus, the width = x = 9 feet

Putting the value of x = 9

then, The length = 3x - 9 = 3(9) - 9

the length = 27 - 9

the length = 18 feet

Therefore, as we know that,

Area = Length × Width

Area = (18 × 9) feet  

Area =   162 square feet.

Now,

Cost of a Tile = $1.69 per sq. ft.

Thus,

Total Cost of tile = $1.69 × 162

Total Cost of tile =  $273.28

Probability that a continuous random variable (x) will take on a value between 34 and 35 is 1/8

Uniform distribution is a type of probability distribution which consists constant probability.

It is also known as Rectangular distribution and

denoted by U( x,y ) .

let X be a continuous random variable then

X ~ U( x,y) where x is maximum value and y is minimum value .

Probability density function of uniform distribution is f(X) = 1/(b-a) , where

b---> maximum value , a---> minimum value

we have provided the interval of uniform distribution as 30 to 38 i.e b = 38 , a = 30

then , f( X) = 1/ (38-30) = 1/8

Probability that X will take on value between c and d is

P ( c ≤X≤ d ) =( d -c )/ (b-a )

Answer:

24 and 41 inches.

Step-by-step explanation:

Let the lengths of the two pieces be a and b.

The total length of the two-piece should be the length of the original board.

Therefore:

a + b = 65

One piece, say b, is 7 inches shorter than twice the length of the other, a.

Therefore, we can write the following equation:

b = 2a - 7

The “2a” represents the twice, and the “-7” represents the 7 shorter inches.

We now have a system of equations:

a + b = 65

b = 2a - 7

We can solve using substitution. Substitute the second equation with the first. Hence:

a + (2a - 7) = 65

Combine like terms:

3a - 7 = 65

Add 7 to both sides:

3a = 72

Divide both sides by 3:

a = 24

So, the shorter piece is 24 inches.

Then, we can use our second equation again:

b = 2a - 7

Since we now know a substitute 24 for a and evaluate. Hence:

b = 2(24) - 7

  = 48 - 7

  = 41

Therefore, the length of the other two pieces is 24 and 41 inches.
