alexdok [17]

Answer:

First figure is a hexagon

second figure is a dodecagon

third figure is a decagon

Step-by-step explanation:

We can classify each figure by how many sides it has.

the first one had 6 sides. a six sided polygon is known as a hexagon

the second one has 12 sides. a 12 sided polygon is known as a dodecagon

the third one has 10 sides. a 10 sided polygon is known as a decagon

Round #7 7) In 2018, the United States Postal Service (USPS) raised its rates for mailing letters. The new charge was $0.50 to m

Anarel [89]

We know that

• The new charge was $0.50 to mail a letter weighing up to 1 ounce, and $0.21 for each additional ounce.

Based on the given information, the expression is

$y=0.50+0.21x$

Where <em>x</em> represents additional ounces, and <em>y</em> represents a cost.

<h2>Hence, the function is</h2> $f(x)=0.21x+0.50$

Multiplying 5 and 3 does NOT tell you the total number of flash cards in the 5 piles. Which is the reason why?

erica [24]

5 * 3 does not tell you the total number of flash cards in 5 piles because you don't know how many cards are in each pile.

A decorative window is made up of a rectangle with semicircles at either end. The ratio of AD to AB is 3:2 and AB is 30 inches.

scZoUnD [109]

Answer: The required ratio will be

$84:1034$

Step-by-step explanation:

Since we have given that

Ratio of AD to AB is 3:2

Length of AB = 30 inches

So, it becomes

$2x=30\\\\x=\frac{30}{2}=15\ inches$

So, Length of AD becomes

$3x=3\times 15=45\ inches$

Now, at either end , there is a semicircle.

Radius of semicircle along AB is given by

$\frac{30}{2}=15\ inches$

So, Area of semicircle along AB and CD is given by

$2\times \frac{\pi r^2}{2}\\\\=\frac{22}{7}\times 15\times 15\\\\=\frac{4950}{7}\ in^2$

Radius of semicircle along AD is given by

$\frac{45}{2}=22.5\ inches$

Area of semicircle along AD and BC is given by

$2\times \frac{1}{2}\pi r^2\\\\=\frac{22}{7}\times \frac{45}{2}\times \frac{45}{2}\\\\=\frac{445500}{28}\ in^2$

And the combined area of the semicircles is given by

$\frac{4950}{7}+\frac{445500}{28}\\\\=\frac{465300}{28}\ in^2$

Area of rectangle is given by

$Length\times width\\\\=AD\times AB\\\\=45\times 30\\\\=1350\ in^2$

Hence, Ratio of the area of the rectangle to the combined area of the semicircles is given by

$1350:\frac{465300}{28}\\\\=1350\times 28:465300\\\\=37800:465300\\\\=84:1034$

Hence, the required ratio will be

$84:1034$
