Answer with Step-by-step explanation:
We are given that:
tanA = 0.45
tanA=
=
⇒ =0.45
⇒ =
⇒ =
⇒ AC= 20
Hence, by pythagoras theorem
AB²=AC²+BC²
AB²=20²+9²
AB²=481
⇒ AB=21.9 units
Hence, the approximate length of AB is:
22 units

Step-by-step explanation:
Distance can be found using this formula:
Where (x₁, y₁) and (x₂, y₂) are the points.
We are given the points O (-3, -2) and P(-3,4). Therefore,
Substitute the values into the formula.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
Solve inside the parentheses first.
- (-3--3)= -3+3=0
- (4--2)= 4+2=6
Solve the exponents.
- (0)²= 0*0=0
- (6)²= 6*6=36
Add.
Take the square root.
The distance is 6.
Answer:
39%
Step-by-step explanation:
It is given that 35 apartments have balconies in them.
While 55 apartments do not have balconies in them.
Total number of balconies is the sum of the apartments. i.e. 35 + 55
= 90 apartments
Therefore for the survey when an apartment is randomly selected, the percentage of the probability of the apartment to have a balcony can be found out by dividing 35 by 90 and then multiply by 100.
i.e.
= 0.38888888
Multiplying by 100, we get
= 0.388888 x 100
= 38.8888 %
= 39 %
