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

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.

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
