Answer:

1. 64 cm²

2. 240 yard²

3. 85.13 cm²

4. 193.36 m²

Step-by-step explanation:

Ques 1: We are given two rectangle with dimensions,

Length = 12 cm, Width = 4.5 cm and Length = 5 cm, Width = 2 cm.

As, we know, Area of a rectangle = Length × Width

So, we have,

Area of 1st rectangle = 12 × 4.5 = 54 cm²

Area of 2nd rectangle = 5 × 2 = 10 cm²

Thus, the total area of the figure = 54 + 10 = 64 cm²

Ques 2: We are given a triangle and a rectangle with dimensions,

Triangle: Base = 24-12 = 12 yd and Height = 8 yd

As, Area of a triangle = (1)/(2) (Base * Height)

i.e. Area of the triangle =  (1)/(2) (12* 8)

i.e. Area of the triangle =  (1)/(2)* 96

i.e. Area of the triangle = 48 yard²

Rectangle: Length = 24 yd, Width = 8 yd

As, we know, Area of a rectangle = Length × Width

i.e. Area of a rectangle = 24 × 8 = 192 yard²

So, the total area of the figure = 48 + 192 = 240 yard².

Ques 3: We are given a triangle and a semi-circle with dimensions,

Triangle: Base = 8 cm and Height = 15 cm

As, Area of a triangle = (1)/(2) (Base * Height)

i.e. Area of the triangle =  (1)/(2) (8* 15)

i.e. Area of the triangle =  (1)/(2)* 120

i.e. Area of the triangle = 60 cm²

Semi-circle: Diameter = 8 cm implies Radius = 4 cm.

So, Area of the semi-circle = (\pi r^(2))/(2)

i.e. Area of the semi-circle = (\pi 4^(2))/(2)

i.e. Area of the semi-circle = (16\pi)/(2)

i.e. Area of the semi-circle = (50.26)/(2)

i.e. Area of the semi-circle = 25.13 cm²

Thus, the total area of the figure = 60 + 25.13 = 85.13 cm²

Ques 4: We are given a rectangle and a semi-circle of dimensions,

Rectangle: Length = 15 m, Width = 7 m.

As, we know, Area of a rectangle = Length × Width

i.e. Area of a rectangle = 15 × 7 = 105 m²

Semi-circle: Diameter = 15 m implies Radius = (15)/(2) = 7.5 m

So, Area of the semi-circle = (\pi r^(2))/(2)

i.e. Area of the semi-circle = (\pi (7.5)^(2))/(2)

i.e. Area of the semi-circle = (176.72)/(2)

i.e. Area of the semi-circle = 88.36 m²

Thus, the total area of the figure = 105 + 88.36 = 193.36 m²

Which of the following equations is equivalent to the equation 6x – y = 1?A. y = 6x – 1
B. y = 6x + 1
C. y = -6x + 1
D. y = -6x – 1

Answers

The expression into an equivalent form would be;  A. y = 6x – 1

What are equivalent expressions?

Those expressions that might look different but their simplified forms are the same expressions are called equivalentexpressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to the expression into an equivalent form.

This expression could also be given as

6x – y = 1

Now, we know that:

6x – y = 1

6x = y + 1

y = 6x - 1

Hence, the required expression into an equivalent form 6x – y = 1 would be;  y = 6x - 1
