3/7-5/6==>
get a common denominator...18/42-35/42==>
subtract nominators...-17/42
answer=-17 over 42 or -17/24
Answer:
70%
Step-by-step explanation:
(90-27)/90
=63/90
=0.7
Changing it to percentage:
=70%
The width is 3m because 3*7 is 21m^2. Also they said the length is 4 more than the width (3+4=7)
Answer:
The first one
Step-by-step explanation:
Because it already give you the y-intercept and you can solve x by doing 4 to 7 have to add 3 and x only have to add 1. It will give you a slope 3/1, so it is 3.
y=3x+1
Step-by-step explanation:
(A) Let a triangle be formed with height of pole h, length of base b and angle of elevation 58°. (Due to lack of a figure).
Tan 58° = h / b = 1.6
(B) Let another triangle be formed with height of pole h, length of base (b + 90) and angle of elevation 36°. (Due to lack of a figure).
Tan 36° = h / (b + 90) = 0.72
(C) <u>Simplifying the two equations</u> :
1.6b = 0.72b + 64.8
b = 64.8 / 0.88 = 73.6 m
h (height of pole) = 1.6 * 73.6 = 117.76 m
