When you do the second step it is 40 so you add one zero from the 7200 and thats where you got the zero
Answer:
comparison groups
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
1/3 - 2/5 = x/15
Make denominators equal.
5/15 - 6/15 = x/15
Cancel the denominators.
5 - 6 = x
-1 = x
Answer:
39
Step-by-step explanation:
Let a and b represent the first and second digits, respectively.
... a = b -6 . . . . . . the first digit is 6 less than the second
... a + b = 12 . . . . .the sum of digits is 12 (an even number)
Using the expression in the first equation, we can substitute for a in the second equation:
... (b -6) +b = 12
... 2b = 18 . . . . . . add 6, simplify
... b = 9 . . . . . . . . .divide by 2
... a = 9 -6 = 3 . . . . from the first equation
The number is 39.
Answer:
The area of rhombus = 24
Step-by-step explanation:
The area of rhombus = base times height
For the given rhombus :
Height = The length of DP
Base = the length of any side of the rhombus as AB
The length ot two point (x₁ , y₁) and (x₂ , y₂) =
From the given figure:
D = (-5,-2) , P = (-3.8 , 1.6) , A = (1,0) , B = (7 , -2)
DP =
= √14.4
AB =
= √40
So,
<u>The area of rhombus = √14.4 * √40 = √576 = 24</u>
