Answer:

1,000 feet

Step-by-step explanation:

From point Q to point R, the x values change by 20 units while the y values stay the same. This side of the polygon has a length of 20

From point R to point S, the y values change by 30 units while the x values stay the same. This side of the polygon has a length of 30

From point S to point T, the x values change by 20 units while the y values stay the same. This side of the polygon has a length of 20

From point T to point Q, the y values change by 30 units while the x values stay the same. This side of the polygon has a length of 30

The total perimeter is 20 + 30 + 20 + 30 = 100 units, each unit represents 10 feet, so the total perimeter is 100(10) = 1,000 feet

Answer:

100 feet

Step-by-step explanation:

side lengths:

y2-y1 = /-10-10/ = 20 units

x2-x1= /20-(-10)/ = 30 units

20+20+30+30 = 100

Find the area of the rhombus

Neporo4naja [7]

Answer:

60 u²

Step-by-step explanation:

Finding second diagonal :-

d' = √{ 17² - 8²}
d' = √{ 289 - 64 }
d' = √{ 225 }
d' = 15 u

Using formula :-

A = 1/2 * d * d'
A = 1/2 * 15 * 8
A = 15 * 4 u²
A = 60 u²

At a profit of 8% a shopkeeper sold a calculator for Rs 1382.40.If he wants to increase his profit by 2%, at what price should h

MAVERICK [17]

Answer: New Price = Rs. 1408

Step-by-step explanation: Selling Price = Rs 1,382.4

Profit = 8%

Increased Profit = 10% (we'll discuss that later)

Costing Price:

Let CP be x

x = 1382.4 - 0.08x

=> x+0.08x = 1382.4

=> 1.08 x = 1382.4

Dividing both sides by 1.08

=> x = Rs 1280

So, the cost price is Rs 1280

Now, Let's discuss about the increased Profit:

Profit %age = 10%

Profit = Profit %age * CP / 100

Profit = 12800/100

Profit = Rs. 128

New Price:

New Price = CP + Profit

New Price = 1280+128

New Price = Rs. 1408
