So multiply 2 x 1.10 = 2.20
                   3 x 95  = 2.85
                   5 x 2.15 = 10.75
Now add all that up    15.80 divide 15.80 by 5 to get 3 dollars and 16 cents(thats how much everyone pays)

or if your going to include tracy to the 5 people which would make 6 it would be 2.63333333333 so round that up to either 2.60 or 2.63

Find m angle ABC <br> I really need the answer to this
damaskus [11]
To find <ABC, the first thing you would need to do is to find angle DBA and the value of x

As <DBE is a right angle, <DBE is on the same straight line as well,meaning that it would be 90° , a right angle as well.

It also mean that the total sum of the angles unknown would be 90°

To find x,we need to set up an equation:
(2x+14)+ (x+7) = 90
3x+21 = 90
3x = 69
x = 23

Thus,<ABC would be
(23)+7
=30°

Hope it helps!

Solve for x. Please help quick, it’s my last question for my test
Sladkaya [172]

Answer:

x = 9

Step-by-step explanation:

84 + (7x + 5) + (180 - (17x-1)) = 180

84 + 7x + 5 + (181 - 17x) = 180

270 + (-10x) = 180

90 = 10x

x = 9

Is the function even or odd?
sweet [91]

Answer:

f(\theta)=\cos(\theta) is an even function.

Step-by-step explanation:

Recall when it means when a function is even or odd. An even function has the following property:

f(-x)=f(x)

And an odd function has the following property:

f(-x)=-f(x)

So, let's test some values for cos(x).

Let's use π/3:

f(\pi/3)=\cos(\pi/3)

From the unit circle, was can see that this is 1/2 (refer to the x-coordinate).

Now, let's find -π/3. This is the same as 5π/3. Thus:

f(-\pi/3)=\cos(-\pi/3)

And again from the unit circle, we can see that this is 1/2.

Therefore, despite the negative, the function outputs the same value.

Cosine is an even function.

Notes:

Cosine is an even function and sine is an odd function. It's helpful to remember these as they can help you solve some trig problems!
