Answer:
the area of rectangle A is 133.33 sq cm
Step-by-step explanation:
let us suppose area of rectangle A be x....hence we get ,
3:5=80/x
or,3/5=80/x
or,3x=80*5
or,x=400/3
x=133.3.3
2 11/12 is your answer because
3-2=1+1=2
and 4/12 - 3/12 = 1/12 + 10/12 = 11/12.
Answer:
Dont use long words, keep your questions short,
Step-by-step explanation:
The angle of elevation<span> of an object as seen by an observer is the </span>angle<span> between the horizontal and the line from the object to the observer's eye (the line of sight). since you did give the horizontal distance between amy and the hoop, so let us represent it as x.
so the angle of elevation = tan^-1 ( (8 - 5.9) / x)
angle elevation = tan^-1 ( 2.1 / x )</span>
Answer:
(- 1, 9 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 6 → (1)
y = 9 → (2)
Substitute y = 9 into (1) and solve for x
9 = - 3x + 6 ( subtract 6 from both sides )
3 = - 3x ( divide both sides by - 3 )
- 1 = x
Solution is (- 1, 9 )
