Because even though 'a' and 'b' are rational, and their squares are
also rational, that doesn't guarantee that the sum of their squares
has a rational square root.
Examples:
1 and 2
Sum of squares = 5
√5 is irrational
2 and 3
Sum of squares = 13
√13 is irrational
4 and 5
Sum of squares is 41
√41 is irrational
'c' is rational only when 'a', 'b', and 'c' form a . . . . . wait for it . . . . .
a 'Pythagorean triple'.
Examples:
3 and 4
Sum of squares is 25
√25 = 5 is rational yay
5 and 12
Sum of squares is 169
√169 = 13 is rational yay
Answer:
percent decrease is 30%
Step-by-step explanation:
Step one:
given data
Cost of scooter= $15.50
selling price= $10.75
Step two:
%decrease = Cost price-selling price/cost price
%decrease = (15.5-10.75/15.5)*100
%decrease =( 4.75/15.75)*100
%decrease = 0.30*100
%decrease =30%
therefore the percent decrease is 30%
it will take Dominic 48 minutes to go 12 miles because it took him 4 minutes every mile so you just multiply 4 times 12
The equation is 2(3x-2)=5
10+12p is the answer to that IXL problem
