Step-by-step explanation:

By understanding the proportions of each section with respect to the entire hexagon we have:  

The first row represents the proportion of each section with respect to the entire hexagon, which is shown below:

{1, 1/2, 1/3, 1/6}

The elements of the second row are obtained by mutiplying all the elements of the first row by 6:

{6, 3, 2, 1}

The elements of the third row are calculated by multiplying all the elements of the first row by 3:

{3, 3/2, 1, 1/2}

And the elements of the fourth row are determined by multiplying all the elements of the first row by 2:

The amount Aisha would pay to paint her living room is £38.50.

The first step is to determine the area of the walls that do not have doors.

Area of a wall = length x width

3 x (2.6 x 3.5) = 27.30 m²

Dimensions of the wall with the door : (2.6m - 2.2m) x (3.5 - 0.8) = 0.4m x 2.7m

Area of the wall with the door : 0.4m x 2.7m = 1.08 m²

Total area of the walls: 27.30 m² +  1.08 m² = 28.38 m²

Number of paint tins needed for the walls : 28.38 / 8 = 3.55 = 4 tins

Cost of the paint tins : (11 x 3) + (0.5 x 11) = £38.50

If Audrey leaves her car in the lot for "t" hours, she would have to pay a total of $6 + $2t for parking.

If Audrey leaves her car in the parking lot for 5 hours, she will have to pay the initial fee of $6 plus $2 for each hour she parked. For 5 hours, she will pay:

Initial fee: $6

Additional fee for 5 hours: $2 * 5 = $10

Total parking cost: $6 + $10 = $16

If Audrey leaves her car in the parking lot for "t" hours, the total parking cost can be calculated as:

Total parking cost = Initial fee + Additional fee for "t" hours

Total parking cost = $6 + $2t

The angle measures in triangle ABC are (d) m∠A = 60°, m∠B = 30°, m∠C = 90°

The side lengths are given as:

AB = 12 inches

BC = 6√3 inches

CA = 6 inches

From the list of options, the angles are 30°, 60° and 90°, respectively.

In a triangle, the angle opposite the largest side is the largest angle and vice versa.

This means that:

∠C = 90° --- opposite AB

∠A = 60° --- opposite BC

∠B = 30° --- opposite CA

Hence, the angle measures in triangle ABC are (d) m∠A = 60°, m∠B = 30°, m∠C = 90°

Answer:

a. The equation should be

4x + 3y = $11.67

8x + y = $12.89

b. The price of one can of soup and the price of one loaf of bread is $1.355 and $2.09

The calculation is as follows:

here we assume the soup be x and bread be y

So, the equations are

4x + 3y = $11.67 .........(1)

8x + y = $12.89.........(2)

Here we need to multiply by 2 in equation 1

8x + 6x = $23.34

8x + y = $12.89

5y = $10.45

y = $2.09

Now x should be

8($2.09) + y = $12.89

x = $1.355

The value of x in the given sector is determined as 7.1.

Total area of the sector = area of the shaded + area of the unshaded

Since shaded and unshaded areas are equal, the value of x is calculated as follows;

πr²θ/360 = πx²60/360 +  πx²60/360

πr²θ/360 = 2(πx²θ/360)

πr² = 2(πx²)

r² = 2x²

x² = r²/2

x² = (10²)/2

x² = 50

x = √50

x = 7.1

Answer:

168 kg oats and 252 kg corn

Step-by-step explanation:

2 equations and 2 unknowns

eq 1: x + y = 420

x is the amount of oats

y is amount of corn

eq 2: 9.4x + 3.4y = 5.8*420

solve equation 1 for x

x = 420 - y

substitute the value of x in eq 2

9.4(420-y) + 3.4y = 2436

y = 252

substitute y in eq 1

x + 252 = 420

x = 168

Solving a system of equations, we will see that Nora bought 2 apples and 6 bananas.

Let's define the variables:

We know that She buys 3 times as many bananas as apples.

y = 3*x

The total cost is $5.

x*$1 + y*$0.50 = $5

Then we have a system of equations:

y = 3*x

x*$1 + y*$0.50 = $5

Replacing the first equation into the second one we get:

x*$1 + (3x)*$0.50 = $5

Now we can solve this for x.

x*$1 + x*$1.50 = $5

x*$2.50 = $5

x = $5/$2.50 = 2

So She bought 2 apples, and:

y = 3*x = 3*2 = 6
