Answer: 166
Step-by-step explanation:
Number of trophies = 3
Total Legos required for all trophies = 324
Number of Legos for largest trophy(A) = 220
Number of Legos for smallest trophy(B) = 135
Number of Legos required for final trophy(C) 
=? 
Total Legos = [Number of Legos for largest trophy(A) + Number of Legos for smallest trophy(B) + Number of Legos required for final trophy(C)] 
324 = 220 +135 + C
324 = 355 + C 
324 - 355 = C
-31 = C
135 + 31 = 166
 
        
                    
             
        
        
        
The answer is d because 4+8=12 and they are 4 units away from eachother:)

Given, PQ⊥PS,PQ∥SR,∠SQR=28 
∘
 ,∠QRT=65 
∘
 
According to the question,
x+∠SQR=∠QRT (Alternate angles as QR is transversal.)
⇒x+28 
∘
 =65 
∘
 
⇒x=37 
∘
 
Also ∠QSR=x
⇒∠QSR=37 
∘
 
Also ∠QRS+∠QRT=180 
∘
 (Linear pair)
⇒∠QRS+65 
∘
 =180 
∘
 
⇒∠QRS=115 
∘
 
Now, ∠P+∠Q+∠R+∠S=360 
∘
 (Sum of the angles in a quadrilateral.)
⇒90

Answer:
The answer to this question can be defined as follows:
In option 1, She buys 4 memory cards.
In option 2, The cost of memory is $40  
Step-by-step explanation:
Given:
Available space is = 105 GB
required space = 1000 GB  
256 GB memory cost $10.
Find needed memory:
=  1000 GB - 105 GB
= 895 GB 
∴ the available memory is 256 GB.
∵ 256 × 4 = 1024  GB 
The total memory she have = 1024 + 105 = 1129 GB
And  she needs to buy 4 memory cards.
The cost of the four memory cards is= 4 ×10 =  $40.
