The first blank is 24, because 80% of 30 is 24.

The second blank is 6. There are 6 left to find because 100% - 80% = 20% and 20% of 30 is 6.

Hope this helped! ♡

There are 30 treasures.

80% are found:
80% of 30 = 0.8 x 30 = 24
Bella found 24 of them

30 - 24 = 6
There are 6 more left to find

Are all quadrilaterals parallelograms?

kondor19780726 [428]

Answer:

No, but all parallelograms are quadrilaterals.

Step-by-step explanation:

Take a trapezoid, for example. A trapezoid is a quadrilateral because it has 4 sides, but it does not contain 2 sets of parallel sides thus making it not a parallelogram.

In the interval 0 degrees < x < 360 degrees, find the values of x for which tan x = 2.7475. Give your answers to the neare

Answer:

<em>Thus, the values of x are 70° and 250°</em>

Step-by-step explanation:

<u>Trigonometric Functions</u>

The tangent is defined as:

$\displaystyle \tan\theta=\frac{\sin\theta}{\cos\theta}$

Given a value for the tangent, there are two angles with the same tangent, one of them being $\theta$ and the other $\theta$ +180°.

We are given:

$\tan x=2.7475$

The angle is the inverse tangent:

$x=arctan (2.7475)$

Using a scientific calculator, we find the first angle:

x=70°

The second angle is found adding 180°:

x=70°+180°=250°

Thus, the values of x are 70° and 250°

Explain how solving -4t < 32 is different from solving 4t <-32.

Thanks for the question!

When you multiply or divide both sides of an inequality, you flip the sign. "Flip," meaning greater than becomes less than and less that becomes greater than.

Hope this helps!
