Answer:
9/15=3/5
so 3/5 is equivalent fraction of the 9/15
Let's call the two numbers a and b. So we know that the difference of the two numbers is 36:
a - b = 36
And we know that their sum is 286:
a + b = 286
We can use either of these equations to solve for one of the variables in terms of the other variable. Let's use the first and solve for a:
a - b = 36
a = 36 + b
Now we plug this into the other equation and solve for b there:
(36 + b) + b = 286
36 + 2b = 286
2b = 250
b = 125
In the equation f(n) = 2n - 7
f(11) = 15
No. A cube is a 3D figure and polygon is a 2D one.
a) Area of rhombus = ½ * (diagonal1)*(diagonal 2)
Let diagonal (D2 )= longer diagonal = 15 and diagonal (D1) = shorter diagonal
90 = ½ (D1)*15
90 = 7.5 D1
Now divide both side by 7.5
90/7.5 = d1
D1= 12 units.
b) Area of rhombus = ½ * (diagonal1)*(diagonal 2)
Let the ratio be ![x](https://tex.z-dn.net/?f=%20x%20)
Diagonal 1= ![2x](https://tex.z-dn.net/?f=%202x%20)
Diagonal 2= ![3x](https://tex.z-dn.net/?f=%203x%20)
147 = ½ * ![(2x)*(3x)](https://tex.z-dn.net/?f=%20%282x%29%2A%283x%29%20)
Multiply both side by 2
294 = ![(2x)*(3x)](https://tex.z-dn.net/?f=%20%282x%29%2A%283x%29%20)
294 = 6![x^2](https://tex.z-dn.net/?f=%20x%5E2%20)
Divide both side by 6
294/6 = 6
/6
49 = ![x^2](https://tex.z-dn.net/?f=%20x%5E2%20)
= 7 unit
