A children's roller coaster ride travels along 3,300 feet of track at an average rate of 15
Olenka [21]

Answer:

150 seconds

Step-by-step explanation:

Remember that

1\ mile=5,280\ feet

To convert miles to feet multiply by 5,280

1\ hour=3,600\ seconds

To convert hours to seconds, multiply by 3,600

step 1

Convert the average rate of miles per hour to feet per second

15\frac{mi}{h}=15(\frac{5,280}{3,600})=22\frac{ft}{sec}

step 2

Find out how many seconds does the ride take to travel this length of track

we know that

The length of the track is 3,300 ft

so

Divide the total length of the track by the speed

\frac{3,300}{22}= 150\ sec

A regular hexagon has an apothem measuring 14 cm and an approximate perimeter of 96 cm.
WINSTONCH [101]
Given:
hexagon
apothem of the hexagon: 14 cm
perimeter of the hexagon: 96 cm

Area of the hexagon = [(3√3) / 2] a²     ; where a is the measure of the side

hexagon has 6 sides.

Perimeter = 6a
96 cm = 6a
96 cm / 6 = a
16 = a

We can also use the area of a triangle to approximate the area of the hexagon. There are 6 triangles in the hexagon .

Area of a triangle = (height * base) / 2
A = (14 cm * 16 cm) / 2
A = 224 / 2 
A = 112 cm²

112 cm²  * 6 triangles = 672 cm²
