278 - 156 = 122
Hannah did not collect money from 122 of the houses in her neighborhood.
Answer:
Step-by-step explanation:
DISTANCE FORMULA
D=(SQRT(X2-X1)^2+(Y2-Y1)^2)
SQRT(1-(-1))^2+(3-(-1)^2)
SQRT((2)^2+(4)^2)
SQRT(4+16)
SQRT(20)
2SQRT(5)
Answer:
The distance r is
Step-by-step explanation:
we know that
Applying the Pythagoras Theorem
where
c is the hypotenuse
a,b are the legs
In this problem we have
substitute and solve for r
Answer:
a) 0.4
b) 0.07
c) 3
e) 1.23
f) 0.19
I) 3.3 = 3.300
j) 5.64
Step-by-step explanation:
0.4 = 4/10
0.07 = 7/100
0.603 = 603/1000
0.64 = 0.64000000
