Answer:

Compare the cost for the each (smallest) unit.

Step-by-step explanation:

You can calculate the cost per unit

For example :

20 ounces of water of brand A cost 1.50

30 ounces of water of brand A cost 2

20 ounces of water cost 1.50/20 = 0.075 dollar per ounce

30 ounces of water cost 2/30 = 0.0677 dollar per ounce

In circle O, the measure of ∠ROW is 110°. What is the measure of arc RAW?

Tanya [424]

Answer:

250°

Step-by-step explanation:

We know that a circle has a total of 360°.

Now we know that ∠ROW is 110° and that Arc RAW has the same End points as ∠ROW.

We can safely assume that arc RAW will be the difference of ∠ROW and 360°.

So we then get:

360° - 110° = 250°

This means that Arc RAW will be 250°

Given:

$m\angle B=90^\circ, m\angle D=90^\circ, AB=6, BD=4, BC=2, DE=x$ .

To find:

The value of x.

Solution:

In triangles ABC and ADE,

$\angle B\cong \angle D$ (Right angles)

$\angle A\cong \angle A$ (Common angles)

$\Delta ABC\sim \Delta ADE$ (AA property of similarity)

We know that the corresponding sides of similar triangles are proportional. So,

$\dfrac{AB}{AD}=\dfrac{BC}{DE}$

$\dfrac{6}{(6+4)}=\dfrac{2}{x}$

$\dfrac{6}{10}=\dfrac{2}{x}$

$\dfrac{3}{5}=\dfrac{2}{x}$

On cross multiplication, we get

$3\times x=5\times 2$

$3x=10$

$x=\dfrac{10}{3}$

Therefore, the value of x is $\dfrac{10}{3}$ units.
