Answer:
900
Step-by-step explanation:
Assume x brick
X*(1/9+1/10)一 10=X/5
X(19/90-1/5)=10
X*(1/90)=10
X=900

Answer:
2047
Step-by-step explanation:
We are given that
Growing rate=0.7%



Using the formula 



Initially when t=0,P=323 million
Substitute the values 


Now, substitute P=400 million





Year=2016+31=2047
Hence,In 2047 the U.S population will reach 400 million people.
 
        
             
        
        
        
Answer:
-0.111c + 1 = 0.889c = c=1
Subtract 0.889c from both sides:
−0.111c+1−0.889c=0.889c−0.889c
−c+1=0
Subtract 1 from both sides.:
−c+1−1=0−1
−c=−1
Divide both sides by -1.:
-c/1 = -1/-1
 
Therefore, your answer is c=1

Find area of one triangle
---------------------------------------------
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 9 x 11.75
Area of triangle = 52.875 ft²
---------------------------------------------
Find area of two triangles
---------------------------------------------
Area of 2 triangles = 52.875 x 2 
Area of 2 triangles = 105.75 ft²
