Answer:
6 8 10
Step-by-step explanation:
This is a simple explanation from online but basically the ratio between the numbers can add up. Any multiple of 3,4,5 triangles work.
You can set up an equation.
Let x = measure of the length.
Width: 2/3x
Length: x
From the question, we know that the perimeter is 70 and based on our prior knowledge, we know that for a rectangle, the perimeter is equal to 2 times the length added to two times the width.
2(2/3x + x) = 70
4/3x + 2x = 70
10/3x = 70
x = 21
So the length is 21 meters.
And since the width is 2/3 the length, 2/3 x 21 is 14.
So the width is 14 meters.
And if you add 21 + 21 + 14 + 14, it will equal 70 meters.
Now let's find the area.
21 x 14 = 294 square meters.
Answer:
The answer is 9.
Step-by-step explanation:
6x - 2 < 5x + 7
6x - 5x < 7 + 2
x < 9
Answer:
The value of X is 62 degrees
Step-by-step explanation:
The arc length L of a circle is given by formula:
L= 2(pi)(r)X / 360 (1)
where pi = 3.14, r is the radius of the circle and X the angle that produces the arc. You want the angle X so we can simplify X in equation (1)
360L=2(pi)(r)X
360L/2(pi)(r)= X
X = 360L/2(pi)(r)
We replace the radius r=9cm the arc L = 9.7 cm and pi and obtain
X = 360* (9.7 cm)/ 2(3.14)*(9cm) = 3492/56.52 = 61.78
That rounded to nearest degree is 62 degrees.
