Answer:
Step-by-step explanation:
Area of a triangle is A = height x base / 2
So plug in what you know.
42 = (14 x b)/2 get rid of the 2 by multiplying both sides by 2 which gives:
84 = 14 x b get rid of the 14 by dividing both sides by 14
b = 84/14
b=6 cm
Answer:
36 + 16 √3
Explanation!
You would first need to simply the radical by breaking the radicand up into a product of known factors!
So the answer would be 36 + 16 √3
If you want decimal form here you go! :)

Hope this helps you out!
Answer:
v=52.5
Step-by-step explanation:
the angle is right so both of the sides should equal 90 degrees
90-(minus)37.5 is 52.5
Answer:0.666666666666 or 2/3
Step-by-step explanation:
What you are doing here is actually pretty simple, since you have a variable (t) and you have its value (8/9) all that you have to do is place the value where your variables is in the equation. 8/9 x 3/4 = 0.666666666666 or 2/3! what you would do to get the final answer is multiply across, so, 3x8 =24 and 4x9 = 36, so far you're at 24/36 which you'd need to simplify to get 2/3!
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.
