As a fraction it would be 163/500 and it is 326 thousand
Answer:
Step-by-step explanation:
3x +2y = 13 -----------------(i)
x + 2y = 7 ----------------(ii)
Multiply the equation (ii) by (-1) and then add.
(i) 3x + 2y = 13
(ii)*(-1) <u>-x - 2y = -7 </u> {Now, add and y will be eliminated}
2x = 6
x = 6/2
x = 3
Plug in x = 3 in equation (i)
3*3 + 2y = 13
9 + 2y = 13
2y= 13 - 9
2y = 4
y = 4/2
y = 2
Answer:
4.08 inches.
Step-by-step explanation:
A cube has six sides, and each of the sides has area of , where is the length of the edge of the cube.
Thus the total surface area of the cube is
Now we are told that this surface area is 100 square inches, therefore , and now we can solve for :
Answer:
the Answer is B.
Step-by-step explanation:
Pythagorean theorem (applicable on right triangles only) says:
Where and are the two legs of the triangle and is the length of the hypotenuse [THE LONGEST SIDE].
We can square each leg on the triangle and take the sum, if that is equal to the square of the longest side, we have a right triangle. Let's check for all of these.
A.
They're not right triangle.
B.
This is a right triangle.
C.
They're not right triangle.
D.
They're not right triangle.
Only B is the right triangle
