Answer:
11.42 dollars
Step-by-step explanation: since you are adding a percentage turn 20% into a decimal. if you do this you will get .2. Next, multiple .2 by 9.52 and you will get 20% of 9.52. Now add this value to 9.52 and you will get 11.42 dollars.
Answer:
Quadratic Equation:
From the standard form of a Quadratic Function, we get:
Discriminant:
From the discriminant, we conclude that the equation will have two real solutions.
State that:
By the way, solving the equation given:
2 16/99 as decimal should be:
2 + (16/99) = 2 +0.17 = 2.17
1.7-3-2.4y= 12y-11.64
-1.3-2.4y = 12y - 11.64
-2.4y = 12y - 11.64
-14.4y = -10.34
y= 10.34/14.4= 5.17/7.20 or 517/720
<u>We are given:</u>
We know that the sum of all interior angles of a Pentagon is 540°
we are given 4 out of the 5 angles
<u>Solving for x:</u>
since the sum of all 5 angles is 540°:
75 + 130 + 135 + x + 90 = 540
x + 430 = 540
x = 540 - 430
x = 110°
