Answer:
129.9 kPa
Step-by-step explanation:
The relationship between temperature T, volume V and pressure P is given by the ideal gas equation which is given as
K = PV/T where K is a constant such that were there is a change of temperature T₁, volume V₁ and pressure P₁ to  temperature T₂, volume V₂ and pressure P₂ then the relationship may be given
P₁V₁/T₁ = P₂V₂/T₂
where T is measured in ⁰K
T₁ = -50 + 273
= 223 ⁰K
T₂ = 102 + 273
= 379 ⁰K
5 × 107/223  = P₂ × 7/379
P₂ = 129.9 kPa
 
        
             
        
        
        
Answer:
37
Step-by-step explanation:
Using order of operations, multiplication is done before addition.
given
7 + 5 × 6 ← perform multiplication
= 7 + 30 ← do the addition
= 37
 
        
                    
             
        
        
        
Answer:
10 m
Step-by-step explanation:
If we draw the diagonal of the rectangle, we form a right triangle where the diagonal is the hypotenuse and the legs are 6 and 8.
This is a well-known Pythagorean triple, which gives the diagonal to be 10 m.
 
        
             
        
        
        
Answer:
   5·7
Step-by-step explanation:
From your knowledge of multiplication tables, you know that ...
   5×7 = 35
Both 5 and 7 are prime numbers, so that is the prime factorization.
