Two farmers each have triangular plots of land in the diagram below with approximate values shown for lengths in feet

Ray Of Light [21]

Answer:

a) Plots are similar
b) x= 5577 feet

Step-by-step explanation:

Refer to attached

<h3>Question</h3>

a) Are the plots of land similar?
b) Find to the exact value of x and rounded to the nearest tenth?

<h3>Solution</h3>

The small triangle have missing angle of 180° - (52° + 58°) = 70°

This is indicating both triangles have same 3 angle measures.

Since all angles are same, the triangles are similar.

Corresponding sides, against corresponding angles are:

6180 and 8240
x and 7436

As per property of similarity, the ratio of corresponding sides is same

6180/8240 = x/7436
x = 6180*7436/8240
x = 5577 feet

Evaluate when a = 8 and b = 4.

ab^2
a−b

ab² = (8)(4)² = 8*16= 128

a - b = 8 - 4 = 4

A and B are partner in a business .A contribution RS 20000 and B rs 30000 a however acts as a manager the understanding being th

Vesna [10]

Answer:

Rs 1,650

Step-by-step explanation:

The given contribution are;

A contributes Rs 20,000, and B contributes Rs 30,000

The percentage of the profit A receives as manager = 25%

The amount of the profit divided in the ratio of their contribution = The remaining profit (75%)

The amount B gets = Rs1,350

The amount A gets = required

The ratio of their contribution at which the remaining profit is shared = 20,000:30,000 = 2:3

Where, out of 5 parts of 75% of the profits, B gets 3, while A gets 2

Let P represent the profit, we have;

B's share = 3/5× 0.75 × P = 1,350

∴ P = (5 × 1,350/3)/0.75 = 3,000

A gets 25% of the profits and 2/5 of the 75% remaining profit

∴ The amount A gets = 0.25×3000 + (2/5)×0.75×3000 = 1,650

Or simply put;

A gets the remainder of the profit which is Rs 3,000 - Rs 1,350 = Rs 1,650

- 3 + 3x = 2x – 13 I have to use more characters...

DENIUS [597]

- 3 + 3x = 2x – 13

Bring -3 to the right side of the equation by adding 3 to both sides

(- 3 + 3) + 3x = 2x – 13 + 3

0 + 3x = 2x - 10

3x = 2x - 10

Bring 2x to the other side by subtracting 2x to both sides

3x - 2x = 2x - 2x - 10

x = -10

Check:

-3 + 3(-10) = 2(-10) - 13

-3 + (-30) = -20 - 13

-33 = -33

Hope this helped!
