Perpendicular lines have opposite reciprocal slopes.
y = 1/4x - 10 is our original equation.
If we flip the slope and change the sign, we get -4
The answer is -4
Rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal
compare ratios of lengths and widths
rectangles A and B
k =
=
← ratio of lengths
k =
=
← ratio of widths
scale factors are equivalent, hence rectangle A is a scaled copy of B
rectangles C and B
k =
=
← ratio of lengths
k =
=
← ratio of width
scale factors (k ) are not equal, hence C is not a scaled copy of B
rectangles A and C
k =
=
← ratio of lengths
k =
← ratio of widths
the scale factors are not equal hence A is not a scaled copy of C
Answer:
4.5
Step-by-step explanation:
7 1/2 X 6 = 45.
Then you just add the decimal point to get 4.5.
Step-by-step explanation:
y of o but you dont have to use y
Answer:
11.8 m
Step-by-step explanation:
Volume = pi×r²×h
95 = pi×1.6²×h
h = 95/(pi×1.6²)
h = 11.8122809326
h = 11.8 m (nearest tenth)
