The area of a trapezoid is calculated using the formula below, where A is the area of the trapezoid, b1 and b2 are the bases of

MA_775_DIABLO [31]

2(\frac{Area}{h} ) - b1 = b2

Step-by-step explanation:

The formula for calculating the area of a trapezoid is the following.

Area = \frac{b1+b2}{2} * h

What we are asked to find is the formula for finding b2. We can do this by rearranging the Area formula and getting b2 by itself on one side.

Area = \frac{b1+b2}{2} * h

\frac{Area}{h} = \frac{b1+b2}{2} .....divide h on both sides

2(\frac{Area}{h}) = b1+b2 .... multiply 2 on both sides

2(\frac{Area}{h} ) - b1 = b2 ....subtract b1 on both sides

Now we have b2 by itself on one side and the formula is rewritten to solve for b2.

The sides of two regular octagons are 3 in. And 6 in. respectively. Find the ratio of their perimeters and their areas

photoshop1234 [79]

The ratio of their perimeters is $\frac{1}{2}$ and the ratio of their areas is $\frac{1}{4}$

Step-by-step explanation:

A regular n-side polygon has

n equal sides
n equal angles
The measure of each interior angle = $\frac{(n-2).180}{n}$
Its perimeter = n × a, where a is the length of its side

<em>V.I.Note: all regular polygons have same number of sides are similar, because their interior angles are equal in measures and their sides are proportion</em>

<em />

∵ There are to regular octagons

- Regular octagon has 8 equal sides and 8 equal angles

∴ The two octagon are similar

∵ Their sides are 3 inches and 6 inches

∴ The constant ratio between their sides = $\frac{3}{6}$

- Divide the two terms of the ratio by 3 to simplify it

∴ The constant ratio between their sides = $\frac{1}{2}$

In similar figures <em>the ratio between their perimeters is equal to the constant ratio between their sides</em>, and <em>the ratio between their areas is equal to square the constant ratio between their sides</em>

∵ The two octagons are similar

∵ The constant ratio between their sides = $\frac{1}{2}$

∵ The ratio between their perimeters = the constant ratio between

their sides

∴ The ratio between their perimeters = $\frac{1}{2}$

∵ The ratio between their areas = (constant ratio)²

∴ The ratio between their areas = $(\frac{1}{2})^{2}=\frac{1}{4}$

The ratio of their perimeters is $\frac{1}{2}$ and the ratio of their areas is $\frac{1}{4}$

Laura paddles in her canoe at a speed of 5 mph for 5 miles. She then hops on her windsurfer and sails for 12 miles at a speed of

Inessa05 [86]

Laura paddles in her canoe at a speed of 5 mph for 5 miles.

As we know that

$\text{Distance=Speed*Time}\\ \\ Time=\frac{Distance}{Speed} \\$

Substitute the values we get

$Time=\frac{5m}{5mph}=1hr.......(i)\\$

Laura hops on her windsurfer and sails for 12 miles at a speed of 6 mph.

Again using the above formula we can write

$Time=\frac{12m}{6mph}=2hr.......(ii)\\$

Hence from equation (i) and (ii), we can say total time of travel $=1hr+2hr=3hr\\$

A granite monument has a volume of 25,365.4 cm3. The density of granite is 2.7 g/cm3. Use this information to calculate the mass

Vaselesa [24]

Answer:

<h3>The answer is 68,486.58 g</h3>

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of granite monument =

25,365.4 cm³

density = 2.7 g/cm³

The mass of the granite monument is

mass = 25,365.4 × 2.7

We have the final answer as

Hope this helps you
