Answer:
180.
Step-by-step explanation: Divide 5 and the $60 and it would give you 12 . So we know that each pizza cost $12, so multiply the 15 pizzas and the 12 dollars. Thus the answer, 180 . Hope this helped lol.
Answer:
Step-by-step explanation:
I don't know where you are in your class, or even what chapter you are in, but I solved this using a right triangle.
We don't need to know the angles, just the sides.
c is the hypotenuse, the line at a tilt
b is the adjacent line, directly below c
a is the opposite line
c = 13
a= 12
b = ?
In order to find b, we use the Pythagorean Theorem, , but we need to rearrange the problem to where we are solving for b instead of c,
So, b = 17.69
Now, we need to evaluate each of the trig. functions:
So, there is your answers, hope that is what you are looking for.
On a graph, go up 7 units and to the right 2 units from the origin
Answer:
A. the angle of <ABC of 80° has a bisector BD because it goes through and makes 2 equal shapes out of angle <ABC.
Answer:
Conjecture : 2xy / ( x + y ) ≤ √xy
Step-by-step explanation:
Harmonic mean of x and y = 2xy/( x + y )
<u>Formulate a conjecture about their relative sizes </u>
we will achieve this by computing harmonic and geometric means
Geometric mean = √xy
harmonic mean = 2xy/( x + y )
Conjecture : 2xy / ( x + y ) ≤ √xy
attached below is the proof
