Step-by-step explanation:
(6+r)^2 = 81 + r^2
36 + 12r+ r^2 = 81 + r^2
12r = 81-36 = 45
r = 15/4 = 3.75
Answer:
86%
Step-by-step explanation:
A percentage is a number or a ratio expressed as a fraction over 100. For example, 50% in fraction form is known as 50/100. 45% is known as 45/100.
Lets say the fraction was 43/50. We already know that a percentage is a number expressed as a fraction over 100, in order to convert this fraction into a percentage, we would have to multiply the denominator by a certain number in order to make it 100.
43/50 = x/100
If we multiply 50 × 2 = 100, so now we have to do the same for the numerator, and also multiply it by 2.
43 × 2 = 86
50 × 2 = 100
Now we know that the fraction is 86/100, now in order to convert it into percantage form, it would just be 86%

Answer:
The distance would be around 9.66 blocks
Step-by-step explanation:
If you draw a straight line from zoo to movie theater, we have a triangle.
The given angle is 86 degrees, the two sides adjacent to it are 6 and 8 and we want to find the side opposite (let it be "p") to the given angle.
We will use cosine rule to find this. The rule is:
Where
a and b are the two adjacent sides to the given angle
a = 6
b = 8
p is what we are looking for
P is the angle given
So, substituting and finding the value:
The distance would be around 9.66 blocks
