Answers

Answer: 36.9

Step-by-step explanation:

For this question you have to find out whether you are using Sin, Cos or Tan.

To work out which one you are using you can use SOH CAH TOA to help you.

SOH- The 'S' is for Sin, the 'O' and the 'H' is for Opposite over Hypotenuse.

CAH- The 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.

TOA- The 'T' is for Tan, the 'O' and the 'A is for Opposite over Adjacent.

As you have the Opposite (the side opposite the angle we're looking for) and the Adjacent (the side next to the angle were looking for) we would be using Tan.

So first you would have to write:

Tanθ=3/4

Then because we want Theta (θ) on it's own we would have to do the inverse to 'undo' the equation. Tan-1 is the inverse of Tan.

θ=Tan-1 3/4

To find the answer you would have to put it in your calculator.

θ=36.9

Hope this helps :)

You prepare8 scoops of dog food for 4 ​dogs, and prepare15 scoops of dog food for 6 dogs. Is there a proportional relationship between the number of scoops and the number of​ dogs?
Choose the correct answer below.

Answers

Answer:

Is there a proportional relationship between the number of scoops and the number of​ dogs?

No.

Step-by-step explanation:

A proportional relationship is something like:

y = k*x

Here y can represent the number of scoops of dog food, and x the number of dogs.

First, we know that for 4 dogs he prepares 8 scoops of dog food, then:

8 = k*4

If the relationship is proportional, then we should have a similar equation for the case of 6 dogs, where he prepares 15 scoops of dog food:

15 = k*6

So if we have the same k in both equations, then there is a proportional relationship between the number of scoops and the number of dogs.

In the first equation we have:

8 = k*4

8/4 = k

2 = k

And in the second equation we have:

15 = k*6

15/6 = k

2.5 = k

The values of k are different, so no, there isn't a proportional relationship between the number of scoops and the number of dogs.

a^2 +b^2 = c^2  where a and b are the legs and c is the hypotenuse

a^2 + (2.1)^2 = (2.9)^2

a^2 +4.41=8.41

a^2 = 8.41-4.41

a^2 =4

Take the square root of each side

a recipe calls for 5/8 cup of sugar for every 5 teaspoons of vanilla. what is the unit rate in cups per teaspoon?

a) 3 1/8
b) 1/8
c) 8
d) 8/25

Answers

Answer:

b) 1/8

Step-by-step explanation:

5/8 ÷ 5 = 1/8

The unit rate in cups per teaspoon is 1/8 cup of sugar.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

5/8 cup of sugar=5 teaspoons of vanilla.

or, 5 teaspoons of vanilla = 5/8 cup of sugar

So, 1  teaspoon of vanilla = (5/8)/5 cup of sugar

(5/8)/5 = (5/8)*(1/5)

(5/8)/5 =1/8

So, 1 teaspoon of vanilla = 1/8 cup of sugar

Hence, the unit rate in cups per teaspoon is 1/8 cup of sugar.
