Rise over run is y over x. 9/5 is 1.8 you have x=20 i plugged in all numbers and when i plugged in 36 i got 1.8 so im sure the answer is D)36

Answer:

The answer of the question is D) 36

Step-by-step explanation:

It is stated that y is directly proportional to the variable x. Therefore, the function equation can be written as below:

f(x)=9*x/5

When x=5, function gives y=9. When x = 20 function is going to be as following:

f(20)=9*20/5=36

Correct answer is D) 36

Suppose an isosceles triangle ABC has A = 45° and b = c = 4. What is the length of a2? A.22.63
weeeeeb [17]

Since b = c, the angles B and C also equal

 so you get
180 - 45 = 135
135/2 = =67.5 for each angle

now we know 2 sides and all 3 angles, use the law of sines to find a

b/sin B = a/sin A

4/(sin 67.5) = a/(sin 45)

a = 4(sin 45)/(sin 67.5)

a^2 = (4(sin 45)/(sin 67.5))^2

a^2 = 9.37

 Answer is C

Answer:

188 legs

Step-by-step explanation:

A game of legs!!

In this question, we are asked to calculate the number of legs of animals present in the question.

Let’s first identify the individual brands of animals present. We have ;

4 dogs, 7 bees, 5 cockroaches, 8 spiders, 3 deers, 4 boars and 2 antlers.

A dog has 4 legs; this means total number of legs contributed by the dogs to the pool will be 4 * 4 = 16 legs

A bee has six legs; total number of bees legs is thus 7 * 6 = 42 legs

A cockroach has 6 legs; total number of cockroaches legs is 6 * 5 = 30 legs

8 spiders have a total of 8 * 8 = 64 legs

3 deers, 4 boars and 2 antlers have 4 legs each making a total of 9 * 4 = 36 legs

The total number of legs present is thus; 36 + 64 + 30 + 42 + 16 = 188 legs
