Decimal Form:
0.92387953
exact form (\sqrt(2+2\sqrt(2)))/(2)
Answer:
a)4
Step-by-step explanation:
(a+b)²=43 eqn 1
(a²+b²)=35 eqn 2
solving eqn 2 by putting the value of (a+b)² by eqn 1
- (a+b)²-2ab=35
- 43-2ab=35
- -2ab=35-43
- ab= -8/-2
- ab =4

Answer:
y=-2/3x-6
Step-by-step explanation:
y=mx+b
m=-2/3
y-y=m(x-x1)
y-(-1)=-2/3(x-(-6))
y+1=-2/3x-4
-1 -1
y=-2/3x-5
They have to ride 3/8 more of the way there. 3/5 miles is 3/8 of the way there, so they need to ride 3/5 of a mile more.
Original ratio: 3 + 8 = 11
240/11 = 21.818
3 x 21.818 = 65.5
11 x 21.818 = 174.5
New ratio: 3 + 2 = 5
240/5 = 48
3 x 48 = 144
2 x 48 = 96
Number of stamps bought = new amount - original amount:
144-65.5 = 78.5
Round to nearest whole number = 79 stamps bought
