What is the circumference of a circle with a radius of 14? Use 3.14 for Pi.

Answer:

b. 36 years

Step-by-step explanation:

Today

Nirmala = x years

Rahul = 3x years

In 13 years

Nirmala = 3x + 13 years

Rahul = 2(x+13) - 1

3x + 13 = 2(x+13) - 1

3x + 13 = 2x + 26 - 1

3x + 13 = 2x + 25

3x - 2x = 25 - 13

x = 12

Nirmala = x years

= 12 years

Rahul = 3x years

= 3(12)

= 36 years

The age of Rahul today is 36 years

Step-by-step explanation:

a)

Unit Price = Cost/Volume

= 9/5

= $1.8/Kg for the 5Kg

4.5/2

= $2.25/Kg for the 2Kg

b)

($2.25-$1.8) per kg

= $0.45

The required solution to the system of equations is (x, y) = (-2, 4). Option B is correct.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
To solve this system of equations, we can set the two expressions for y equal to each other, since they both represent the same value of y,

x + 6 = -0.5x + 3

Simplifying and solving for x, we get:

1.5x = -3

x = -2

Now that we have the value of x, we can substitute it into one of the original equations to find the value of y. Using the first equation, we have,

y = x + 6

y = -2 + 6

y = 4

Therefore, the solution to the system of equations is (x, y) = (-2, 4).

Solution :-

As per provided information in the given question, we have been given that the Radius of a cylinder is 4.4 meters. The height of a cylinder is 5 meters. We have been asked to find the volume of a cylinder.

To calculate the volume of a cylinder, we will apply the formula below :-

[tex] \bigstar \: \: \: \boxed{ \sf{ \: \: Volume_{(Cylinder)} = \pi r^2 h \: \: }}[/tex]

Substitute the given values into the above formula and solve for Volume :-

Answer:

$3.50

Step-by-step explanation:

Given that the  cost of 3 pencils and 2 markers is $1.30. Let the cost of  a pencil be $p and that of a marker be $m then

3p + 2m = 1.30

Also, the cost of 2 pencils and 3 markers is $1.20 will result

2p + 3m = 1.20

Solve both simultaneously

3p + 2m = 1.30

2p + 3m = 1.20

multiply the first by 2 and the second by 3

6p + 4m = 2.60

6p + 9m = 3.60

subtract the second from the first

4m - 9m = 2.60 - 3.60

-5m = -1

Divide both sides by -5

m = 0.20

substitute into equation 1

3p + 2(0.2) = 1.30

3p + 0.4 = 1.30

3p = 1.30 - 0.40

3p = 0.90

Divide both sides by 3

p = 0.30

The total cost of 7 pencils and 7 markers

= 0.30 * 7 + 0.20 * 7

= 2.10 + 1.40

= $3.50

Given:

Height of the cylinder = 21 ft

Dimeter of the cylinder = 10 ft

To find:

The volume of the cylinder.

Solution:

We have,

Dimeter of the cylinder = 10 ft

So, radius is half of diameter, i.e., 5 ft.

Volume of the cylinder is

[tex]V=\pi r^2h[/tex]

Where, r is the radius and h is the height.

Putting [tex]\pi=3.14[/tex], r=5 and h=21, we get

[tex]V=(3.14)(5)^2(21)[/tex]

[tex]V=(3.14)(25)(21)[/tex]

[tex]V=1648.5[/tex]

Therefore, the volume of the cylinder is 1648.5 cubic ft.

Answer: 1/4

Step-by-step explanation:

If you add the equations:

12a + 3b = 1

-2a + 7b = 0

------------------- (you get):

10a + 10b = 1 (divide by 10)

a + b = 1/2 (divide by 2 since average of two numbers is their sum divided by 2)

(a + b) / 2 = 1/4

Answer: 0.05

Step-by-step explanation:

1. 12a+3b=1

a= (1-3b)/12

2. 7b-2a=0

7b-2((1-3b)/12)

b=1/45

a=(1-3b)/12=(1-3(1/45))/12=7/90

Lastly: (7/90+1/45)/2=0.05

It's 87 feet I got the answer right

The  height of the tree is estimated as 87 ft.

The height of the tree can be estimated using trigonometric ratios. Therefore,

tan 44° = opposite / adjacent

tan 44° = h / 90

h = 90 tan 44°

h = 90 × 0.9656887748

h = 86.9119897326

h ≈ 87 ft

Therefore, the  height of the tree is estimated as 87 ft.
