Answer:
Step-by-step explanation:
Angle BOA = length of arc/radius
=8.4/8
= 1.05 radians
= 1.05*180/pi
= 60.16°
= 60°
Angle AOC = 45°
Angle BAC = 60.16 + 45
= 105.16°
Arc BAC = radius * angle (degrees) * pi /180
= 8 × 105.16 × (3.14159/180)
= 14.683 cm
= 14.7 cm
Answer:
part 7 = 15cm
Step-by-step explanation:
A)
d =240/a
B) 2 loads of gravel
Step-by-step explanation:
Step 1:
Given one load of gravel is 240 ft2.
We have depth = 240/area
Hence the inverse variation model is d =240/a
Step 2 :
The length and breadth of the playground is 40 ft and 24 ft
The depth of the playground is 6 in = 6/12 ft
Hence the volume of the given playground is 40 * 24 * 6/12 = 480 cu ft.
There is 240 ft2 of gravel in one load
So we need 480 cu ft of gravel = 480/240 = 2 loads of gravel.

A Number squared decreased by ten
We will do this with steps:-
Step 1 - "A number ". So, Let's say any number be x
Step 2 - "A number squared". Our number x is squared i.e. x²
Step 3 - "A number squared" ( i.e. x² ) is decreased by ten
x² - 10
This is your answer.
Hope this helps you :)
