Answer 1

Answer:

area = 1539√3 in²

Step-by-step explanation:

three hexagons and one triangle:

each of the three hexagons are composed of 6 equilateral triangles just like the center triangle.

So you have 19 equilateral triangles with each side being 18 inches long.

The height (h) of a triangle will be:

h² = 18² - 9² = 324 - 81 = 243

h = √243

h = 9√3

area of one triangle = 1/2bh = (1/2)(18)(9√3) = 81√3

81√3(19 triangles) = 1539√3 in²

What is the measure of arc PQ

Answers

Answer:

x = 15

arc PQ = 110°

ΔPQR is an acute triangle

Step-by-step explanation:

(6x) + (8x-10) + (10x+10) = 360°

combine like terms:

24x = 360°

x = 15

arc PQ = 8(15) - 10° = 110°

Answer:

x=15

measure of arc PQ is 110 degrees

Step-by-step explanation:

Hello There!

Remember the circumference of a circle is 360 degrees

So to find x we use the equation

360=8x-10+6x+10x+10

now we solve for x

combine like terms

-10+10 cancels out

8x+6x+10x=24x

now we have

24x=360

divide each side by 24

24x/24=x

360/24=15

we´re left with x = 15

Now lets find the measure of arc PQ

to do so we plug in 15 into x for 8(15)-10

8*15=120

120-10=110

so the measure of arc PQ is 110

a long distance phone charge of $1.40 for 10 min or 4.50 for 45 min. which is better

Answers

Answer: $4.50 for 45min is better.

Step-by-step explanation:

The fee per min for phone charge of $1.40 for 10 min: 1.40/10 = $0.14/min

The fee per min for phone charge of $4.50 for 45 min: 4.50/45 = $0.1/min

$0.14/ min > $0.1/min

4.50 for 45min is better.
