Vertical angles are equal
3x - 3 = 6(x - 10)
3x - 3 = 6x - 60
3x = 57
x = 19
Answer
x = 19
Answer:
y=5
Step-by-step explanation:
y = 0,1 × 10 × 5 = 5
I hope I answered correctly
The volume of a cube is given by;
(One length side of the cube)³ - remember all sides of a cube are the same, just like how both sides of a square are the same. This is essentially the area of the square at the base, multiplied by the height of the cube.
Hence why we that that, for example 4³, is "4 cubed"
So we know that;
volume = (side length)³
Alternatively we could say that;
Side length = ∛volume
(we have just found the cube root of both sides here, remember we can do what we like to an equation, as long as we do the same to both sides!)
Because we cubed side length to get volume, side length must be the cubic root of the volume, the ∛.
We know that the volume is 1000 cubic feet, so;
Side length = ∛1000
∛1000 = 10
So one side length is 10 feet.
since we know those two triangles are similar then we can use proportions.
Answer:
A) 7 meters
Step-by-step explanation:
As you know the length of the rectangle you would first multiply the length of 35 by 2, which gives you 70. This is because the perimeter is the sum of all the lengths and that a rectangle has 2 sets of different identical lines. Then you would minus 70 from 84, which gives you 14. This is because you are now finding out the sum of the set of widths. Then you would divide 14 by 2 to find the width, which gives you 7 meters.
1) Multiply 35 by 2.
2) Minus 70 from 84.
3) Divide 14 by 2.
