Simplest way to do this:
number of books= 120
percentage represented by 120= 100%
increase current percent by 55%= 155%
: . 55% increase = original number of books * (155%)
= 120 * (155/100)
= 186
Answer:
<1=83
<2=97
<3= 83 (given)
<4=97
<5=83
<6=97
<7=83
<8=97
Step-by-step explanation:
They give you the angle for 3 which is 83, so from there all you have to do is find the equivalent angles which are angle 1,5,7. Then for angles 2,4,6,8 you subtract 83 from 180 and you get 97.
Answer:
Step-by-step explanation:
Since the pile of sand is conical, we would apply the formula for determining the volume of a cone which is expressed as
Volume = 1/3 × πr²h
Where
r represents the radius of the cone.
h represents the vertical height of the cone.
π is a constant whose value is 3.14
From the information given,
Diameter = 18 feet
Radius = Diameter/2 = 18/2
Radius = 9 feet
Height = 10 feet
Therefore,
Volume = 1/3 × 3.14 × 9² × 10
Volume = 1/3 × 3.14 × 81 × 10
Volume = 847.8 ft³

Step-by-step explanation:
Answer:
m < ANM = 36 degrees.
AM = 9.40 cm to the nearest hundredth.
Perimeter = 94.05 cm to the nearest hundredth.
Step-by-step explanation:
As we have a regular pentagon:
m < ANB = 360 / 5
= 72 degrees
So m < ANM = 1/2 * 72
= 36 degrees.
In the triangle ANM, AN = 16 so
sin 36 = Am / 16
AM = 16 sin36
= 9.4045 cm.
AB = 2 * AM = 18.809 cm
So as all sides are equal:
Perimeter = 5 * 18.809
= 94.05 cm.
