Answer:
R = 8,228,571.43 (Approx)
Step-by-step explanation:
Given:
R = x²/y
x = 4.8 x 10⁵
y = 2.8 x 10⁴
Find:
Value of R
Computation:
R = x²/y
R = (4.8 x 10⁵)²/ (2.8 x 10⁴)
R = 23.04 x 10¹⁰ / (2.8 x 10⁴)
R = 8.22857.. x 10⁶
R = 8,228,571.43 (Approx)
 
        
             
        
        
        
Answer:
B
Step-by-step explanation:
We can divide using the calculator by entering in 59, 584 first followed by 14 before the division sign.
We can also perform long division:
        __<u>4256_</u>____
  14  |   59, 584
         <u>  -56__</u>__
               35
            <u>   -28____</u>
                78
              <u> -70_</u>___
                  84
              <u>   -84_</u>___
                    0
 
        
             
        
        
        
Answer:
Step-by-step explanation:
5 3/4 + 2 1/2
Add the whole numbers first 
5 + 2
Add the fractions next
3/4 + 1/2 = 3/4 + 2/4 = 5/4 = 1 and 1/4
The total is
7 + 1 1/4 = 8 1/4
 
        
             
        
        
        
Step-by-step explanation:
In triangle,
 <u> XYZ</u>  <u>PYZ</u>
 XZ = PZ = 12cm
 XY = PY = 5cm
 YZ = YZ (Common side)
<em><u>Hence</u></em><em><u>,</u></em>
As three sides of the two triangles are equal so,
<em><u>Triangle XYZ is congruent to Triangle PYZ by SAS congruence condition </u></em>
