Boarding Kennel Problem

In a boarding kennel, dogs number 12 more than 2 times the number of cats. If there are 75 animals, how many cats are boarded?

Step 4: Set up strategy sentences. Use them to set up and solve mathematical equations.

•The number of cats plus the number of dogs is 75.

•The number of dogs is 12 more than 2 times the number of cats.

If c is the number of cats, how do we express the number of dogs?

A. 2c - 12

B. 2(c + 12)

C. 2c+12

Answer:

  C. 2c+12

Step-by-step explanation:

"12 more than 2 times the number of cats" means "12 + 2c", where c is the number of cats.

To get 2 times, we multiply by 2. To get 12 more, we add 12.

This means Square root (^1/2). this is kind of hard to read. anyways. 32^(1/2) separates into 4^(1/2) and 8^(1/2), which further separates into 4^(1/2) and 2^(1/2), root 4 becomes 2, their are two root 4's, so you get 2 x 2, and you are left with 2^(1/2) now why go to all this trouble. because now you can multiply the 4 you created (2x2) times, the 7... giving you 28*2^(1/2) now subtract it from the the other one with root 2. -5*2^(1/2), giving you 23*2^(1/2)-...idk what that last bit is. if its a odd number then this is the end of the problem, if you can get it to root 2. then do that and simplify.

Answer:

3/5 or 0.6

Step-by-step explanation:

Here, given the value of tan theta , we want to find the value of sine theta

Mathematically;

tan theta = 0pposite/adjacent

Sine theta = opposite/hypotenuse

Firstly we need the length of the hypotenuse

This can be obtained using the Pythagoras’ theorem which states that the square of the hypotenuse equals sum of the squares of the two other sides.

Let’s call the hypotenuse h

h^2 = 3^2 + 4^2

h^2 = 9 + 16

h^2 = 25

h = √(25)

h = 5

Now from the tan theta, we know that the opposite is 3

Thus, the value of the sine theta = 3/5 or simply 0.6

The mean of a population being sampled is 64, and the standard deviation is 6. If the sample size is 50, the standard error of t
Serjik [45]
Given:
mean = 64
standard deviation = 6
sample size = 50

Standard error of the sample mean = standard deviation / √sample size

Standard error = 6 / √50 = 6/7.07 =<span> 0.85</span>
