A suit and 4 ties = 292
a suit = 200
4 ties = 292 - 200
4 ties = 92
4T = 92
4T/4 = 92/4
T = 23
Each tie costs 23 dollars
hope this helps
The total area of the field will be 320 feet²
<em><u>Explanation</u></em>
Each plot is 8×8 feet in size. That means, the length and width of each plot are both 8 feet.
<u>Formula for the area</u> is:
So, the <u>area of each plot</u> will be:
Now each worker is given a plot with the area of 64 feet² and there are total 5 workers.
So, the total area of the field will be:
U can add 6 on each side. So it’s y/10 = 10 then you can multiply by 10 by each side so y=100
Answer:
true
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
The hypotenuse is the longest side thus is (4x + 1)
The legs are 2x and (4x - 1)
Using Pythagoras' theorem, then
(4x + 1)² = (2x)² + (4x - 1)² ← expanding factors
16x² + 8x + 1 = 4x² + 16x² - 8x + 1 , that is
16x² + 8x + 1 = 20x² - 8x + 1 ( subtract 20x² - 8x + 1 from both sides )
- 4x² + 16x = 0 ( multiply through by - 1 )
4x² - 16x = 0 ← factor out 4x from each term
4x(x - 4) = 0
Equate each factor to zero and solve for x
4x = 0 ⇒ x = 0
x - 4 = 0 ⇒ x = 4
Now x > 0, thus x = 4
2x = 2(4) = 8
4x - 1 = 4(4) - 1 = 16 - 1 = 15
4x + 1 = 4(4) + 1 = 16 + 1 = 17
Thus
perimeter = 8 + 15 + 17 = 40 cm
