Answer:

Rajan = 436.36 rupees and Kamal = 363.63 rupees

Step-by-step explanation:

Total ratio = 11/30

Amount to be shared = 800

Rajan = Individual ratio / Total ratio x the total amount to be shared

1/5 ÷11/30 × 800 = 436.36

Kamal = 1/6 ÷ 11/30 × 800 = 363.63

#5 The MAC is 4 centimeters. Find the circumference of B. Round your answer to the hundredths.
bixtya [17]

Answer:

C ≈ 11.71 cm

Step-by-step explanation:

using the ratio arc  AC : circumference C = angle at centre of sector : 360°

\frac{AC}{C} = \frac{123}{360} , that is

\frac{4}{C} = \frac{123}{360} ( cross- multiply )

123 × C = 4 × 360 = 1440 ( divide both sides by 123 )

C = \frac{1440}{123} ≈ 11.71 cm ( to the nearest hundredth )

For the following question, find the area of the triangle. give the answer to the nearest tenth. The drawing may not be to scale
Alina [70]

Answer:

Option A

10.5 m²

Step-by-step explanation:

The area of a triangle is half the product of its base by its height.

A = 0.5bh

Where b is the base and h is the height.

In this triangle b = 6.1 m.

The height of this triangle is a line perpendicular to its base that goes to the vertex opposite the base.

We do not know this length. But this line h divides the triangle into two rectangular triangles.

So for these two triangles the angle that is opposite to the height h is: 47 °

Therefore we know that senx is defined as:

senx =\frac{opposite side}{hypotenuse}

Where:

Opposite side = h

hypotenuse = 4.7 m

x = 47

Sin(47) = \frac{h}{4.7}\\\\h = (sin47)(4.7)\\\\h = 3.437

Finally, the area is:

A = 0.5(3.437)(6.1)\\\\A = 10.5m^2

The value of x from the given expression is 5/6

<h3>Expansion of equation</h3>

Given the expression to expand expressed as:

15 = 3/5(6x + 20)

We are to determine the value of x

15(5) = 3(6x + 20)

Expand

75 = 18x +60

Collect like terms

18x = 75 - 60

18x = 15

x = 15/18

x = 5/6

Hence the value of x from the given expression is 5/6
