Answer:There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?

Step-by-step explanation

There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?

Legs of a chicken = 2

Legs of a rabbit = 4

Total heads = 72

Total legs= 200

Let's assume that each of them has minimum 2 legs.

So 72*2 = 144 legs

Remaining legs: 200-144= 56

These remaining legs belong to rabbit because rabbit has 4 legs each.

2*Rabbits= 56

Rabbits= 56/2 = 28

Out of 72, 28 are rabbits. So there are 72-28= 44 chicken.

Distance from the tip to the middle of the turbine = Radius of the circular turbine

Radius of the circular turbine = 32 meters

Circumference of the circular turbine = distance the turbine will travel in one revolution

We know that :

[tex]\tt \: \color{hotpink}circumference \: of \: a \: circle \color{plum}= 2\pi r[/tex]

Circumference of the circular turbine :

[tex] = \tt2 \times \frac{22}{7} \times 32 [/tex]

[tex] = \tt\frac{2 \times 22}{7} \times 32[/tex]

[tex] =\tt \frac{44}{7} \times 32[/tex]

[tex] =\tt \frac{44 \times 32}{7} [/tex]

[tex] =\tt \frac{1408}{7} [/tex]

[tex]\color{plum} =\tt 201.06 \: m[/tex]

▪︎201.06 m can be roughly rounded off to 200.96.

▪︎Thus, the distance the turbine will cover in one revolution = 200.96 m

▪︎Therefore, the correct option is (A) 200.96

Step-by-step explanation:

Area of a circle: [tex]A_\circ =\pi r^2[/tex] where r is a radius of this circle

8 equal section means area of one is:  [tex]A=\dfrac{\pi r^2}{8\ }[/tex]

r = 12 mm

[tex]A=\dfrac{\pi\cdot 12^2}{8\ }=\dfrac{144\pi}{8}=18\pi[/tex]

Step-by-step explanation:

x = 1/2 Arc AB ( Relation between inscribed angle and corresponding arc)

x = 1/ 2 * 124

x = 62°

y = x ( Inscribed angles on standing on same arc are equal)

y = 62°

Answer:

p = 2

Step-by-step explanation:

Since, (2p-1,p) is a solution of the equation 9y + 12 = 10x.

Therefore, plug x = 2p - 1 & y = p in the above equation.

9p + 12 = 10(2p - 1)

9p + 12 = 20p - 10

12 + 10 = 20p - 9p

22 = 11p

p = 22/11

p = 2

Answer:

base =5   because all angles=60, so an equilateral triangle

C. x = 1.5y

This is the answer

As, 3y/2x = 1.5y/x

Students who play video games = 259°

Students who don't play video games = 360° - 259°

= 101°

Students who don't play video games = 101°/360° * 1,619

Answer: 120

Step-by-step explanation:

3+2=5

Let x be the amount of money to be shared

Paul’s share which is (3/5)x is 60+ Quinn’s share which is (2/5)x

Therefore

(3/5)x= (2/5)x + 60

(3/5)x - (2/5)x= 60

(x/5)=60

Cross multiply

x= 60*5=300

It means that Quinn’s share is (2/5)(300)= 120

The amount of money that Paul and Quinn have will be $180 and $120, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Paul and Quinn share some cash in a proportion of 3:2, Paul gets 60 a larger number than Quinn.

Let 'x' be the share of Paul and 'y' be the share of Quinn. Then the equation is given as,

x: y = 3: 2          ...1

x = y + 60         ...2

From equations 1 and 2, then we have

(y + 60) / y = 3/2

2y + 120 = 3y

y = 120

Then the value of the variable 'x' is given as,

x = 120 + 60

x = 180

The amount of money that Paul and Quinn have will be $180 and $120, respectively.

Answer:

Adults= 110

Children= 340

Step-by-step explanation:

Given data

let adults be x

and children be y

x+y= 450----------1

2x+y=680---------2

from 1

x= 450-y

put this in 2

2(450-y)=680

900-2y=680

900-680=2y

220=2y

y= 220/2

y= 110

x+110= 450

x= 450-110

x=340

Answer:

7x^4-y^3-3

Step-by-step explanation:

Answer:

the answer is x= 5 and y = 1.5

Here we have been given with two equations and we will solve them by elimination by substitution method inorder to get the value of x and y.

★ From Equation No 2 :-

>> x + 2y = 8

>> x = 8 - 2y

★ In Equation No 1 :-

Substituting here the value of x which we got above as (8 - 2y).

>> 5x - 4y = 19

>> 5 (8 - 2y) - 4y = 19

>> 40 - 10y - 4y = 19

>> 40 - 14y = 19

>> -14y = 19 - 40

>> -14y = -21

>> 14y = 21

>> y = 21 / 14

>> y = 1.5

★ Finding out value of x :-

>> x = 8 - 2y

>> x = 8 - 2 (1.5)

>> x = 8 - 2 × 1.5

>> x = 8 - 3

>> x = 5
