Answer:
15
Step-by-step explanation:
20^2 + x^2 = 25^2
= 400 + x^2 = 625
= x^2 = 225
= x = 15
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
1 Kg of carrot = 40 p
1 1/2 Kg of carrot = 40 *  = 20 * 3 = 60 p  = £ 0.60
  = 20 * 3 = 60 p  = £ 0.60
1 kg of potato = 52 p
3 kg of potato = 52 *3 = 156 p =  £1.56
1 box of tea bags = 90 p
Number of boxes for  £1.80 = 1.80 ÷ 0.90  = 2 boxes
4 packs of yogurt =  £4.80
1 pack of yogurt   = 4.80 ÷ 4 =  £1.20
Total = 0.60 + 1.56 + 1.80 +4.80 =  £ 8.76
 
        
             
        
        
        
26 = 1, 3, 9, 13 i added 4 just incase u need sum extra
        
             
        
        
        
For this you need the pythagorean theorem.
5 squared is: 25
25+25= 50
then u need the square root of 50 which is approximately= 7.07107 cm
The length of the diagonal AB is 7.07107 cm
        
             
        
        
        
Answer:
100>=500-15x
Step-by-step explanation:
He needs at least 100, so it's greater than OR equal to 100. He starts with 500 and goes down 15 each week. The x stands for the amount of weeks that are in the school year. Sorry for the terrible formatting on the greater than or equal to.
