Answer:
$1.1
Step-by-step explanation:
First take if 110% is equals to $1.21 what about 100%
1.21×100=121÷110= $1.1

Step-by-step explanation:
Answer:
<h3><X = 63</h3>
Step-by-step explanation:
USing SOH CAH TOA
sin theta = opposite/hypotenuse
sin <X = WV/VX
sin <X = 8/9
<X = arcsin(8/9)
<X = arcsin(0.8889)
<X = 62.7 degrees
Hence the value of x is approximately 63degrees
Answer:
Step-by-step explanation:
Perimeter = 20.56mm
Given the perimeter, find the diameter
= 20.56
D = 20.56 ÷
D = 6.54 mm
Perimeter of the Semicircle = half the circle arc + the straight line (Diameter)
Semicircle = 0.5(20.56) + 6.54cm
Semicircle = 16.83mm
Here the base angle given is 51°.
The side opposite to 51° is y
The hypotenuse is given as 12.
The trigonometric ratio associating opposite & hypotenuse is sin
We know sin = Opposite/ Hypotenuse
Substituting the values of angle , opposite & hypotenuse
We have
y/12 = sin 51°
Multiplying both sides by 12 we get
y=12 × sin 51°
y = 9.326
Rounding to the nearest hundredths we get
y = 9.33
