The area of a triangle is,A=1/2 bh, b=base and h=Heights.
Bingel [31]

Answer:

16

Step-by-step explanation:

To solve this equation you need to do the opposite to factor everything out. Since the 6 is being multiplied you need to divide it by 6 and whatever you do to one side you do to the other:

48=1/2b(6)

6÷6=1

48÷6=8

8=1/2b

Multiplying by 1/2 is the same as dividing by 2. So what we want to do is multiply by 2:

8=1/2b

1/2×2=1

8×2=16

16=b meaning you base is 16

To check your answer you can put 16 in as b

48=1/2(16)6

48=1/2(96)

Remember multiplying by 1/2 is the same as dividing by 2:

48=48

Which expression is equivalent to the radical expression shown below when it is simplified?
babymother [125]

Answer:

\sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}

Step-by-step explanation:

We need to solve the expression

\sqrt{\frac{3}{64} }

We know that \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}

and 64 = 8*8

Solving we get

=\frac{\sqrt{3}}{\sqrt{64}}\\=\frac{\sqrt{3}}{\sqrt{8*8}}\\=\frac{\sqrt{3}}{\sqrt{8^2}}\\=\frac{\sqrt{3}}{8}

So \sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}

In the right triangle shown, the third side can be represented by the expression
Westkost [7]

The third side can be represented by D) x = \sqrt{z^{2} } -y^{2} .

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.

In the given triangle, the hypotenuse is the side that is represented by z. Another side on the triangle is represented by the value y.

Step 2:

Assume the other side of the triangle measures x units.

So according to the Pythagorean theorem,

z^{2}  = x^{2} +y^{2} , x^{2} = z^{2} - y^{2} .

x = \sqrt{z^{2} } -y^{2} which is option D.
