Answer:
-1/125 is a terminating decimal. -7/60 is a repeating decimal.
Step-by-step explanation:
When you convert -1/125 into a decimal, you get −
0.008.
_
When you convert -7/60 into a decimal, you get −
0.11 6.
It looks difficult but it’s pretty easy. Just use the Ln function to bring down the powers then simplify.
1st :The angle of depression 30° = the angle of elevation (from the truck to the height of the building.
2nd :
cos 30° = (adjacent side)/(hypotenuse)
cos 30° = x/100, but cos 30°= (√3)/2
(√3)/2 = x/100 and x = (100√3)/2
and x = (50.√3) = 86.60 m
Answer:
r= 7.14 (rounded to 2 decimal places)
Step-by-step explanation:
We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.
Distributive property is a(b+c) = ab + ac
Now, the steps of solving are shown below:

Hence, value of r is 7.14 (rounded to 2 decimal places)
