Complementary angles together form a 90 degree angle. I don’t understand the question to well, but if two angles are next to each other and one of them is ten degrees, the other angle would be 80 is Together they form a right angle. Does my explain make sense? Sorry I hope this helps
Answer:
-19.68
Step-by-step explanation:
(0.2 + (-5) × (4.1)
-4.8 × (4.1)
-19.68
30% = .3
.3(24.40a + 14.50c)
24.40 = cost of adult ticket
14.50 = cost of child ticket
a = # of adult tickets sold
c = # of child tickets sold
.3 * 24.40a + .3 * 14.50c
answer: 7.32a + 4.35c
It equal to 24 because you have to multiply or divide first then you can add or subtract
The formula for a cone is given as:
<span>V = π r^2 h / 3 --->
1</span>
Where,
V = volume of the cone
r = radius of the circle base of the cone
h = is the perpendicular length from the center of the
base of the cone to the tip at the top
It was given that:
h = d
but d = 2 r, therefore:
h = 2 r
Substituting this to equation 1:
<span>V = π r^2 (2 r) / 3 </span>
V = 2 π r^3 / 3
Since r = x, the answer from the choices is:
<span>2πx3</span>
