7 because it is whole number
Answer:
r = 6 3/23
Step-by-step explanation:
-128+138r=718
add 128 to each side
-128+128+138r=718+128
138r = 846
divide each side by 138
138r/138 = 846/138
r = 846/138
divide top and bottom by 2
r = 423/69
divide top and bottom by 3
r = 141/23
change this to a mixed number
r = 6 3/23
If 5/3% of some number is 4.75, then 1/3% of that number would be 4.75/5. Then multiply that answer by 3 to get 3/3=1% of the number, and finally multiply by 100 to get 100%.
Answer:
14.29cm
Step-by-step explanation:
Height of the building=10cm
Angle of depression=60°
We are therefore asked to find the distance from the stone to the
the foot of the building;Therefore we use Tan ratio which is opp/adj;
Let the distance from the stone to the foot of the building be x;
10/x=Tan60°
10/x=1.7/1
We then cross multiply to get 1.7x=10
x=10/1.7
=10*10/1.7*10
=100/17
=14.29cm.
