You just have to multiply the percentage by the amount:
(150/100)×$63 
1.5×$63= $94.50
If you aren't allowed a calculator, then just find half of $63 (the 0.5 of the fraction) and add it to $63 (the 1. of the fraction).
$63÷2= $31.5
$63+$31.5= $94.50
        
                    
             
        
        
        
Answer:
Total area = 237.09 cm²
Step-by-step explanation:
Given question is incomplete; here is the complete question.
Field book of an agricultural land is given in the figure. It is divided into 4 plots. Plot I is a right triangle, plot II is an equilateral triangle, plot III is a rectangle and plot IV is a trapezium, Find the area of each plot and the total area of the field. ( use √3 =1.73)
From the figure attached,
Area of the right triangle I = 
Area of ΔADC = 
                         = 
                         = 
                         = 
                         = 
                         = 30 cm²
Area of equilateral triangle II = 
Area of equilateral triangle II = 
                                                 = 
                                                 = 73.0925
                                                 ≈ 73.09 cm²
Area of rectangle III = Length × width
                                  = CF × CD
                                  = 7 × 5
                                  = 35 cm²
Area of trapezium EFGH = 
Since, GH = GJ + JK + KH
17 = 
12 = 
144 = (81 - x²) + (225 - x²) + 2
144 - 306 = -2x² + 
-81 = -x² + 
(x² - 81)² = (81 - x²)(225 - x²)
x⁴ + 6561 - 162x² = 18225 - 306x² + x⁴
144x² - 11664 = 0
x² = 81
x = 9 cm
Now area of plot IV = 
                                 = 99 cm²
Total Area of the land = 30 + 73.09 + 35 + 99
                                     = 237.09 cm²
 
        
             
        
        
        
1 ft = 12 inches
(1 ft)^3 = (12 inches)^3
1 cubic foot = 1728 cubic inches
You'll multiply by the conversion factor (1278 in^3)/(1 ft^3) to convert from cubic feet to cubic inches. Notice how the cubic feet ft^3 unit is at the bottom of the conversion fraction, so that the cubic feet units cancel.
Answer: A) multiply by 1728
        
             
        
        
        
Answer:
Option B is correct

Step-by-step explanation:
Given that:
 and
 and  are supplementary.
 are supplementary.
prove that: 
It is given that:
 and
 and  are supplementary.
 are supplementary.
By definition of supplementary
⇒ .....[1]
            .....[1]
From the figure, you can see that:
 and
 and  are also supplementary.
 are also supplementary.
⇒ .....[2]
            .....[2]
By [1] and [2] we have;
⇒
Simplify:

Since ∠2 and ∠3 are corresponding angles.
Corresponding angles states when the two lines are parallel, then Corresponding Angles are equal and vice versa.
by definition we have;
 proved!
