Answer:
326m²
Step-by-step explanation:
Find the area of each side and find the total sum from each individual area:
2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326
So the surface area of the prism is 326m²
 
        
             
        
        
        
Jason = 142 cm = 1.42 m
Amy = 137 cm = 1.37 m
Joseph = 1397 mm = 1.397 m
From shortest to tallest
I) Amy, Joseph, Jason
        
             
        
        
        
Since x is our unknown number, on one side of our equation we will have the "<span>Subtracting two times a number from 10", and on the other will be -3. So,
-3=10-2x</span>
        
             
        
        
        
Answer:
8/3
Step-by-step explanation:
Given that:
Cost of violin = 13200 plus VAT at 20%
Cost of violin = (100 + 20)% * 13200
Cost of violin = 1.20 * 13200 = £15,840
Instalment pay = (360 * 12) = 4320
Therefore, deposit made equals ;
Total cost - Instalment pay
£(15,840 - 4320) = £11,520
Hence, ratio of deposit made to the total Instalment payment made ;
£11520 / £4320 = 8 / 3
 
        
             
        
        
        
Answer:
The equation of parabola is given by : 
Step-by-step explanation:
Given that vertex and focus of parabola are 
Vertex: (4,-3) 
Focus:( ,-3)
,-3)
The general equation of parabola is given by.
 , When x-componet of focus and Vertex is same
, When x-componet of focus and Vertex is same  
 , When y-componet of focus and Vertex is same
, When y-componet of focus and Vertex is same 
where Vertex: (h,k)
and p is distance between vertex and focus
The distance between two points is given by :
L=
For value of p:
p=
p=
p=
p= and p=
 and p=
Since, Focus is left side of the vertex,
p= is required value
 is required value
Replacing value in general equation of parabola,
Vertex: (h,k)=(4,-3) 
p=
