Answer:
4.1, 2.21, 0.25,0.042
Step-by-step explanation:
you have to add a 0 onto the first one because it will bring it to be equal to most of the others
Let h be the numbers of hours, f be the one-time fee and c the cost charged. The equation is

Since you pay $15 per four, plus the fee. We can solve this equation for the fee:

If we plug c=195 and h=9, we have

<em>Hello there, and thank you for asking your question here on brainly.
<u>Answer: The three different types of angles are an acute angle, which is an angle that is an angle that measures from 1</u></em>° <em><u>to 89°. A right angle, that specifically measures to 90</u></em>°. <em><u>Finally, an obtuse angle that measures from 91° to 179°. An angle that also measures 180° is a straight line, and is called a straight angle.

Answer:
D) 57.5°
Step-by-step explanation:
As the question is not complete. So, let's suppose it is a right angle triangle then, we can apply Pythagoras theorem to calculate the hypotenuse or the third side.
Pythagoras Theorem =
=
a = 7 and b = 11
= 49
= 121
Plugging in the values, we will get:
= 49 + 121
= 170
c = 
To calculate the unknown angle B, we can use law of sine.
Law of sine =
=
=
So,
= 
= 
Sin90 = 1
sinB = 
B =
(
)
B = 57.5°
