a whole is always fraction wise "1", whether is 5/5 or 4/4 or 1,000,000/1,000,000 it'd round up to "1", just 1 whole.

we know how much 3/4 of his land is, so the "whole land" will be in quarters, 4/4 or namely "1".

let's firstly convert the mixed fraction to improper fraction and then proceed.

[tex]\stackrel{mixed}{1\frac{4}{5}}\implies \cfrac{1\cdot 5+4}{5}\implies \stackrel{improper}{\cfrac{9}{5}} \\\\[-0.35em] ~\dotfill\\\\ \begin{array}{ccll} acres&whole\\ \cline{1-2} \frac{9}{5}&\frac{3}{4}\\[1em] x&\frac{4}{4} \end{array}\implies \cfrac{~~\frac{9}{5} ~~}{x}=\cfrac{~~ \frac{3}{4}~~}{\frac{4}{4}}\implies \cfrac{~~\frac{9}{5} ~~}{\frac{x}{1}}=\cfrac{~~ \frac{3}{4}~~}{1}\implies \cfrac{9}{5}\cdot \cfrac{1}{x}=\cfrac{3}{4}[/tex]

[tex]\cfrac{9}{5x}=\cfrac{3}{4}\implies 36=15x\implies \cfrac{36}{15}=x\implies \cfrac{12}{5}=x\implies 2\frac{2}{5}=x[/tex]

Answer:

#565 is the best answer I can give you

Answer:

yes

Step-by-step explanation:

The numerator of the improper fraction 2 + 17/20 (which is the decimal 2.85 written as an improper fraction) is 57.

Here, we have to convert the decimal number 2.85 to an improper fraction.

2.85 has a whole number part of 2.

The decimal part 0.85 can be written as 85/100.

85/100 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:

85 ÷ 5 = 17

100 ÷ 5 = 20

So, 85/100 simplifies to 17/20.

The whole number part is 2, and the fraction is 17/20.

So, the improper fraction is:

2 + 17/20.

To find the numerator, multiply the whole number part (2) by the denominator of the fraction (20), and then add the numerator of the fraction (17):

Numerator = (Whole number part × Denominator) + Numerator of the fraction

Numerator = (2 × 20) + 17

Numerator = 40 + 17

Numerator = 57.

So, the numerator of the improper fraction 2 + 17/20 (which is the decimal 2.85 written as an improper fraction) is 57.

The extraneous solution of the logarithmic problem [tex]\rm log_3(18x^3)-log_3(2x) = log_3 144[/tex] is -4.

A log function is a way to find how much a number must be raised in order to get the desired number.

[tex]a^c =b[/tex]

can be written as

[tex]\rm{log_ab=c[/tex]

where a is the base to which the power is to be raised,

b is the desired number that we want when power is to be raised,

c is the power that must be raised to a to get b.

Solving the function using the basic logarithmic value, we get,

[tex]\rm log_3(18x^3)-log_3(2x) = log_3 144\\\\ log_3\dfrac{(18x^3)}{(2x)} = log_3 144\\\\ log_3(9x^2)= log_3 144\\\\\text{Taking antilog}\\9x^2 = 144\\x = \sqrt{\dfrac{144}{9}}[/tex]

If we solve further we will get that the value of x can be either -4 or 4, if take the value of x as -4, in the beginning then you will get log₃(18(-4)³) as the log of negative value which is impossible.

Hence, x=-4 is an extraneous solution.

If the coordimate is reflected over y = -2, hence the resulting coordinate wil be A = (4, -2), B = (2, 3), C = (-6, 2) and D = (2, 2)

Given the coordinate of the quadrilateral shown below

A = (-2, -2)

B = (-1, 3)

C = (3, 2

D = (-1, 2)

Reflecting the coordinates over the y - axis will give:

A = (2, -2)

B = (1, 3)

C = (-3, 2)

D = (1, 2)

Step-by-step explanation:

The hypotenuse of a right triangle is the longest side. In this case, since the longest side is √117 cm, then c=√117.

Answer: B) √117

The correct answer is B) √117

Step-by-step explanation:

As seen, the figure is a right triangle. The hypotenuse is the longest side of the triangle, so the correct option is B) √117. Since the longest side is √117cm, the this means that c = √117cm

We are given with a equation of Circle and we need to find it's radius and it's equation in standard form . But , let's recall , the standard equation of a circle is [tex]{\bf (x-h)^{2}+(y-k)^{2}=r^{2}}[/tex] where (h,k) is the centre of the circle and radius is r . Proceeding further ;

[tex]{:\implies \quad \sf x^{2}+12y+22x+y^{2}-167=0}[/tex]

Collecting x terms , y terms and transposing the constant to RHS ;

[tex]{:\implies \quad \sf (x^{2}+22x)+(y^{2}+12y)=167}[/tex]

Now , as in standard equation their is a whole square , so we need to develop a whole square in LHS , for which we will use completing the square method , as coefficient of x² and y² is 1 , so adding 121 and 36 to LHS and RHS .

[tex]{:\implies \quad \sf (x^{2}+22x+121)+(y^{2}+12y+36)=167+121+36}[/tex]

[tex]{:\implies \quad \sf (x+11)^{2}+(y+6)^{2}=324\quad \qquad \{\because a^{2}+2ab+b^{2}=(a+b)^{2}\}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{\{x-(-11)\}^{2}+\{y-(-6)\}^{2}=(18)^{2}}}}[/tex]

On comparing this with the standard equation , we got our centre at (-11,-6) and radius is 18 units

Answer:

[tex]m=8[/tex]

Step-by-step explanation:

Given the following question:

[tex]10=\frac{5m}{4}[/tex]

In order to find the answer, we have to remember when we have a two-step equation like this to multiply on both sides, and then divide both sides to isolate the variable.

[tex]10=\frac{5m}{4}[/tex]
[tex]4\times10=40[/tex]
[tex]40=5m[/tex]
[tex]5m=40[/tex]
[tex]5m\div5=m[/tex]
[tex]40\div5=8[/tex]
[tex]m=8[/tex]

Hope this helps.

Ok so I don't know if it is (5m)/4 or 5(m/4) so I'll solve both

If it's (5m)/4 :

(5m)/4 = 10
5m = 10 x 4 = 40
m = 40/5 = 8

If it's 5(m/4)

5(m/4) = 10
m/4 = 10/5 = 2

m = 2 x 4 = 8

so first circumference = 2π R

now it is given that circumference - 30 cm = Diameter;

Diameter = 2πR - 30 = 2 R { diameter = 2 times Radius}

now solving equations:

2πR -2R = 30

πR - R = 15

R ( π - 1 ) = 15

R ( 22/7 - 1) = 15

R ( 15/7 ) = 15

R = 15 x 7 / 15

R = 7 cm

Answer:

7.01 cm

Step-by-step explanation:

Circumference = 2πr

=> d + 30 = 2πr

=> 2r + 30 = 2πr

=> 2r(π - 1) = 30

=> 2.14r = 15

=> r = 15/2.14

Now, the cost of plastering it's 4 walls is Rs 8000 at the rate of 50 /m². So, we can find the area of the walls of the room by dividing 8000 by 50 i.e:

➙ A = Total cost / cost per m²

➙ 8000 / 50

➙ 800 / 5

➙ 160m²

In a cuboid , there are a pair of two opposite and equal rectangular sides, and area of rectangle is given by :

So, area of 2 walls along length :

➙ 2 × 3x × h

➙ 6xh

Area of 2 walls along breadth:

➙ 2 × breadth × height

➙ 2xh

Sum of areas of these four walls will be equal to the area of the walls, that we have find earlier;
