What i got was that 2/5 is greater 1/10 but it can also be 4/10>1/10 or 2/5>1/10
Answer:
-5.50
Step-by-step explanation:
it’s -5.5. You just subtract -0.25 on the side where it’s negative and add 0.25 for the side that’s positive.
Suppose that Eldi has x years old now :
x + 4 = 3 × ( x - 10 )
x + 4 = 3x - 30
Add both sides 30
x + 4 + 30 = 3x - 30 + 30
x + 34 = 3x
Subtract both sides x
x - x + 34 = 3x - x
34 = 2x
2x = 34
Divide both sides by 2
2x ÷ 2 =34 ÷ 2
x = 17
_____________________________
Thus Eldi is 17 .
Surface Area of a Cone = (pi)*(radius)*(radius) + (pi)*(radius)*(length)
radius = 5
length = 10
SA = 25pi + 50pi = 75pi or about 235.619
