Answer: 30

Step-by-step explanation:

If we were to draw diagonal BD, then we would create two congruent triangles, and we could find the area of each using the formula [tex]A=\frac{1}{2} ab \sin C[/tex].

However, since there are two triangles, we can double this, giving us [tex]A=ab \sin C[/tex].

So, the area is [tex]A=(10)(6)(\sin 30^{\circ})=\boxed{30}[/tex]

Answer:

¥4630.50

Step-by-step explanation:

Compound Interest Formula

[tex]\large \text{$ \sf A=P(1+\frac{r}{n})^{nt} $}[/tex]

where:

Given:

Substitute the given values into the formula and solve for A:

[tex]\implies \sf A=4000\left(1+\dfrac{0.1}{2}\right)^{2 \times 1.5}[/tex]

[tex]\implies \sf A=4000\left(1.05\right)^{3}[/tex]

[tex]\implies \sf A=4630.50[/tex]

Answer:

¥4630.50

Step-by-step explanation:

Here,

ATQ, as well,the interest is payable in half-yearly.

We know that,

[tex] \boxed{\rm \: A = P \bigg(1+ \cfrac{ \cfrac{r}{2} }{100} \bigg) {}^{2n} }[/tex]

Substitute the values

[tex]A = 4000 \bigg(1 + \cfrac{5}{100} \bigg) {}^{2 \times \frac{3}{2} } [/tex]

Now solve.

[tex]A = 4000 * (21/20)^3[/tex]

[tex] \implies \: A = 4000 \times \cfrac{21}{20} \times \cfrac{21}{20} \times \cfrac{21}{20} = \cfrac{21 \times 21 \times 21}{2} [/tex]

[tex] \implies \: A = \: \yen \: 4630.50[/tex]

Hence,the sum of ¥ 4000 will be amounted to ¥4630.50 in 1 1/2 years.

[tex] \rule{225pt}{2pt}[/tex]

This question arises:Why we used that formula?

Reason:

The compound interest is calculated half-yearly, the formula changes a little.In this case for r we write r/2 and for n we write 2n because a rate of r% per annum is r/2% half-yearly and n years = 2n half year So this is the reason.

Step-by-step explanation:

the area of a circle is

pi × r²

r is the radius (= half of the diameter) of the circle.

radius in our car is 12/2 = 6 yd

and we are to use 3.14 as pi.

so we get as area

3.14 × 6² = 3.14 × 36 = 113.04 yd²

Answer:

b= -18

Step-by-step explanation:

x=3, y= -6, m=4

y=mx+b

-6 = 4 x 3 + b    Solve for b

-6 = 12 + b

-6-12 = b

b= -18

Answer:

b = -18

Step-by-step explanation:

    Slope = m = 4

Plugin the value of slope in the above equation.

    y = 4x + b

Now, the line passes through the point (3 , -6). Substitute x and y coordinates in the above equation.

     -6 = 4*3 + b

     -6 = 12 + b

      b = -6 - 12

      b = -18

Answer:

3.5 meter is the answer.

Answer:

3.5 Meters

Step-by-step explanation:

5 Meters is equivalent to 5000 millimeters

1 day = 300mm

5 days = (300*5)

= 1500 mm

= 5000 mm - 1500 mm

Yarn left = 3500 mm

= 3.5 Meters

A cylinder is a three-dimensional structure formed by two parallel circular bases. The lateral and the total surface area of the cylinder are 113.1 yd² and 169.7 yd².

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centers overlap each other to form a right cylinder.

Lateral area of the cylinder = Area of the curved surface

                                             = 2πR × H

                                             = 2 × π × 3yd × 6yd

                                             = 36π yd²

                                             = 113.0973 yd² ≈ 113.1 yd²

The total surface area of the cylinder

         = Area of the two bases + Area of the curved surface

         = 2(π × 3²) + 113.0973 yd²

         = 56.54866 yd² + 113.0973 yd²

         = 169.6459 yd² ≈ 169.7yd²

Hence, the lateral and the total surface area of the cylinder are 113.1 yd² and 169.7 yd².

1.The temperature will be, T2= 169.8 K

2. The volume if the temperature is 318 K is 0.170 L

Charles's law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.

Given: V1= 250 ml=0.25L

V2=150 ml= 0.15 L

T1= 10 °C=283 K, T2=?

Now using Charles law

V1/T1=V2/T2

0.25/283=0.15/T2

T2= 169.8 K

2. T1= 20 °C= 293 K

    V1= 160 cm³

     T2= 318 K

Step-by-step explanation:

If the value of the angle θ is 77.32°. Then the value of cos 2θ will be the negative 0.90.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The trigonometric equation is given below.

tan θ = 40/9

tan θ = 4.444

Then the angle θ will be

θ = tan⁻¹(4.444)

θ = 77.32°

Then the value of cos 2θ will be

cos 2θ = cos (2 x 77.32°)

cos 2θ = cos 154.64°

cos 2θ = - 0.9036

cos 2θ ≅ - 0.90
