Use the diagram attached below. Find the straight distance between the zoo and movie theater.
Vesnalui [34]

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:

p^2=a^2+b^2-2abcosP

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:

p^2=a^2+b^2-2abcosP\\p^2=6^2 + 8^2 - 2(6)(8)Cos(86)\\p^2=36+64-96Cos(86)\\p^2=100-96Cos(86)\\p^2=93.3033\\p=\sqrt{93.3033}\\p=9.66

The distance would be around 9.66 blocks

A middle school has a speech club with a total of 18 students. The ratio of girls to boys is 4:5. How many girls are in the spee
Fantom [35]
The ratio is 4:5
so girls=4x
and boys=5x
(because you don't know how many boys or girls there are)
then the equation would be
4x+5x=18
9x=18
so x=2
 then 2 times 4 which equals 8
and 2 times 5 which equals 10

so there are 8 girls and 10 boys
