The measure of angles A, B , C and D°are 36°, 63°, 71° and 111° respectively

To find the measure of angles of A, B, C and D, you need to apply some of the angle geometry concepts as follows:

1. m<A

(x+24)° and A = 3x

Since alternate angles are equal, thus:

3x° = (x+24)°

3x -x = 24

2x = 24

x =24/2 = 12

Also, A = 3x = 3(12) = 36°

2. m<B

B = 10x-27 and 7x

Since corresponding angles are equal, thus:

10x -27 = 7x

10x -7x = 27

3x = 27

x = 27/3 = 9

Also, B = 10x -27 = 10(9) -27 = 90-27 = 63°

3. m<C

C = (5x+1)° and (6x-13)°

Since corresponding angles are equal, thus:

(5x+1)° =  (6x-13)°

6x -5x = 13+1

x = 14

Also, C = 5x+1  = 5(14) + 1 = 70+1 = 71°

4. m<D

(6x+3)° and D = (4x+39)°

Since alternate angles are equal, thus:

6x+3 = 4x+39

6x-4x = 39-3

2x=36

x = 36/2 =18

Also, D = 4x+39 = 4(18) + 39 = 72+39 = 111°

Therefore, the m<A = 36°, m<B = 63°, m<C = 71° and m<D =111°. Since B, A,  H and E correspond to m<A, m<B, m<C and m<D respectively, so type BAHE in the answer box

The 27.4 m² of carpet is needed for three bedrooms.

Firstly we will calculate the area of each room.

Area of bedroom a = 3.1 × 3.1

Area of bedroom a = 9.61 m²

Area of bedroom b = 2.9 × 3.2

Performing multiplication on Right Hand Side of the equation

Area of bedroom b = 9.29 m²

Area of bedroom c = 2.5 × 3.4

Area of bedroom c = 8.5 m²

Total area of all the rooms = 9.61 + 9.29 + 8.5

Performing addition on Right Hand Side of the equation

Total area of all the rooms = 27.4 m²

It was 33 degrees warm in the afternoon

From the question, we have the following parameters that can be used in our computation:

In the morning = 5 degrees above zero

Afternoon = Rise of 27 degrees

The degree of warmth in the afternoon is then calculated as

Degree of warmth = Temperature In the morning + Rise of the temperature

Substitute the known values in the above equation, so, we have the following representation

Degree of warmth = 5 + 27

Evaluate the sum

Degree of warmth = 33

Hence, the temperature is 33 degrees

The equation y = 3x +a / 2x - 5 can be expressed in terms of a and y as x = (a - 5y) / (2y-3)

Given equation y = 3x + a / 2x - 5

= y(2x - 5) = 3x + a

= 2xy - 5y = 3x + a

= 2xy - 3x = a - 5y

= x(2y-3) = a - 5y

Hence, x = (a - 5y) / (2y - 3)

First, we will move the denominator 2x-5 and multiply it by y giving us 2xy-5y. Next, we will move all the terms which contain only a and y to one side and the rest remaining to another side, giving us 2xy - 3x = a - 5y. Since we need to express the equation in terms of x we take it as common from left-hand side of the equation and the remaining part we move to the right-hand side as the denominator. Hence we get our equation in terms of a and y as x = (a - 5y) / (2y - 3).

Step-by-step explanation:

The number of atoms in standard form is 4 × 10²⁵ atoms

Standard form is number written in the form a × 10ⁿ where 1 ≤ a < 10 and n is an integer

Since there are about 40 trillion cells in the human body. and each cell consists of about 100 trillion atoms, we have that

40 trillion cells = 40 trillion × 1 cell

Also, 1 cell = 100 trillion atoms.

So, 40 trillion × 1 cell = 40 trillion × 100 trillion atoms.

Now, we know that 1 trillion = 1000 billion

So, Number of atoms =  40 trillion × 100 trillion atoms

=  40 × trillion × 100 × 1 trillion atoms.

= 40 × 1000 billion × 100 × 1000 billion atoms.

= 40 × 1000 × 100 × 1000 × 1 billion × 1 billion atoms.

We know that 1 billion = 1000000000

So,

= 40 × 1000 × 100 × 1000 × 1 billion × 1 billion atoms.

= 40 × 1000 × 100 × 1000 × 1000000000 × 1000000000 atoms

= 40000000000000000000000000

= 4 × 10000000000000000000000000

= 4 × 10²⁵ atoms
