Where, 11.88571 represents the Coefficient of X, which is the slope, the change in direct labor hours per hour change in Indirect labor expense.

Answer:

it is a right triangle

Step-by-step explanation:

Answer:

No, it's not a right triangle

Step-by-step explanation:

Use a^2 + b^2 = c^3 to find if it's a right triangle

a^2 + b^2 = c^3

(13)^2 + ([tex]\sqrt{29}[/tex] )^2 = (14)^2

169 + 29 = 196

Answer:

Rs 300000

Step-by-step explanation:

Given that,

Length of a rectangular park, l = 150 m

Breadth, b = 100 m

We need to find the cost of fencing the park at the rate of 20 per metre. The area of a rectangle is given by :

A = lb

So,

[tex]A=150\times100\\\\A=15000\ m^2[/tex]

Cost of fencing,

[tex]C=15000\times 20\\\\C=Rs\ 300000[/tex]

So, the required cost is Rs 300000.

Step-by-step explanation:

9. Isosceles triangle

10. Right triangle

11. Equilateral triangle

12. Scalene triangle

13. Obtuse angle triangle

The perimeter of the floor in the scale drawing is 36 inches.

What is the area of the rectangle?

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

The scale of the drawing is 10 inches for 40 feet, which means that every inch in the drawing represents 4 feet in reality.

To find the perimeter of the floor in the scale drawing, we can add up the length of each side in the drawing, where every inch represents 4 feet.

The length of the floor is 40 feet, which is equal to 10 inches in the scale drawing (40/4=10). So, the length of the scale drawing is 10 inches.

The width of the floor is 32 feet, which is equal to 8 inches in the scale drawing (32/4=8). So, the width of the scale drawing is 8 inches.

Therefore, the perimeter of the floor in the scale drawing is:

P = 2(length + width)

= 2(10 + 8)

= 2(18)

= 36 inches

hence, the perimeter of the floor in the scale drawing is 36 inches.

Angle A:60

Angle B:120

AngleD:60

Angle E:60

Angle F:120

Angle G:120

Angle H:60

Step-by-step explanation:

There are supplementary angles that add up to get 180 so 120+ __=180

60 is the missing Angle of A and D and since the lines are parallel and we also have vertical angles. The angles are going to be either 120 or 60

Answer:

288

Step-by-step explanation:

If you didnt know a triangle has the area of a square/2

so basically what im saying is the area of that square/2 equals the area of the triangle

to find the area of the square you take 24 and square it

24^2=576

finally we divide that by 2

576/2=288

so the area of the triangle is 288
