True or false: Every kite is a rhombus, but not every rhombus is a kite.

horsena [70]

This is false. Kites can be shaped in many different ways so not all kites are rhombuses. Also, even the kites that look like rhombuses may not be rhombuses. Most kites have 2 pairs of sides with the same length. But, in order to be a rhombus all the sides have to be the same length but not all sides are the same length on a typical kite.

0.8% of 150 is what numbers and how do you write the equation with a variable in it.

Tanzania [10]

Answer:

1.2

Step-by-step explanation:

1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: $\frac{0.8}{100} * 150 = x$

2. Now, let's solve for x!

$\frac{0.8}{100} * 150 = (0.008)(150)$
$(0.008)(150) = \frac{6}{5}$
$\frac{6}{5} = 1\frac{1}{5}$
$1\frac{1}{5} = 1.2$
$1.2$

Therefore, 0.8% of 150 is 1.2!
