A- 998.8×997.7=996502.76
B- 998.84×997.73=996572.6332
C- 998.843×997.731=996576.6252
D - 999×998=997002
So D is the answer
        
             
        
        
        
The volume is (area of cross-section) x (length) . 
-- The cross-section is a triangle.  The area of a triangle is
Area = (1/2) (base) (height) .
In this one, the base is 9/4 m and the height is 3-1/3 m .
Area = (1/2) (9/4 m) (3-1/3 m)
Area = (1/2) (9/4) (10/3)
Area = 90/24 m² .
-- Volume = (area of cross-section) x (length)
Volume = (90/24 m²) x (7-1/3 m)
Volume = (90/24) x (22/3) m³
Volume = (1,980 / 72) m³
<em>Volume = 27.5 m³  </em>
 
        
             
        
        
        
Answer:
Step-by-step explanation:
If m∠A + m∠B = m∠B + m∠C, subtract  m∠B from both sides  [ subtraction property of equality ].
We get that m∠A  = m∠C     and by the  symmetric property of equality,  m∠C = m∠A
 
        
             
        
        
        
Answer:(-2, 2)
Step-by-step explanation:
7q² - 28 = 0
Add 28 to bothside
7q² - 28 + 28 = 0+ 28
7q² = 28
Divide bothside by 7
7q² / 7 = 28/7
q² = 4
Take the square root of bothside
√q² = ±√4
q = ± 2
q = -2 or q =2
q = (-2, 2)
 
        
             
        
        
        
Answer:
x = 9b/C
Step-by-step explanation:
Cx – 4b = 5b
Add 4b to each side
Cx – 4b+4b = 5b+4b
Cx = 9b
Divide by C
Cx/C = 9b/C
x = 9b/C
