The formula for the area A of a triangle is A=(1/2)bh, where b is the length of the base and h is the height. Rearrange the form

zalisa [80]

Answer:

$b=\dfrac{2A}{h}$

Step-by-step explanation:

The formula for the area of a triangle is given by :

$A=\dfrac{1}{2}bh$ ...(1)

Where b is the length of the base and h is the height.

We need to find the value of b from the above formula.

Cross multiplying equation (1) we get :

$2A=bh$

Now dividing both sides by h. So,

$\dfrac{2A}{h}=\dfrac{bh}{h}\\\\b=\dfrac{2A}{h}$

So, the correct option is (D) i.e. $\dfrac{2A}{h}$ .

A wooden crate in the shape of a cube has a volume of 1

ladessa [460]

ANSWER

B. 8

EXPLANATION

Volume of wooden crate is

$\frac{1}{27} {ft}^{3}$

The cubic blocks have side length,

$l = \frac{1}{6} ft$

The volume of each cubic blocks is,

$v = {l}^{3}$

$= ( \frac{1}{6} )^{3} = \frac{1}{216}$

Number of blocks that can go into the crate is,

$= \frac{ \frac{1}{27} }{ \frac{1}{216} }$

$= \frac{1}{27} \times \frac{216}{1}$

$= 8 \: blocks$
