Set this up as a proportion.
400/15 = x/6
Solve for x.
I just hope to help! :)
Answer: If the radius is 23 then the answer is 1661.9 (WHEN ROUNDED & WITHOUT). If the radius is 11.5 the answer is 415.5 (WHEN ROUNDED)
Step-by-step explanation:
The formula for the area of a circle is: radius x radius x pi/3.14
Answer:
Step-by-step explanation:
Step 3:
Let LM = x
OK = KP = 12 units [Radii of circle K]
LN = LP = 8 units [Radii of circle L]
Therefore, KL = KP + PL
KL = 12 + 8
= 20 units
Step 4:
Since, ΔKOM and ΔLNM are the similar triangles,
By the property of two similar triangles, corresponding sides of these similar triangles will be proportional.
12x = 8(x + 20) [By cross multiplication]
12x = 8x + 160
12x - 8x = 160
4x = 160
x = 40
Step-by-step explanation:
25)
(x + 96) + (x + 96) = 180° (interior angles)
2x + 192 = 180°
2x = 180° - 192°
2x = - 12°
x = - 12°/2
x = - 6°
Therefore
x + 96 = - 6+96 = 90°
26)
(20x + 5) + (24 x - 1) = 180° (interior angles)
44x + 4 = 180°
44x = 180° - 4°
44x = 176°
x = 176°/44
x = 4°
Therefore
20x + 5 = 20*4+5 = 80+4 =84°
27)
6x = 5x + 10 (corresponding angles)
6x - 5x = 10
x = 10
Therefore
6x = 6* 10 = 60°
28)
(x + 109) + (x + 89) = 180° (interior angles)
2x + 198 = 180°
2x = 180° - 198°
2x = - 18°
x = - 18°/2
x = - 9°
Therefore
x + 89 = - 9+96 = 87°
Answer:
b(4) = -8
Step-by-step explanation:
We are to find the 4th term.
n = 4
b(n) = 1(-2)ⁿ⁻¹
b(4) = 1(-2)⁴⁻¹
b(4) = 1(-2)³
b(4) = 1(-8)
b(4) = -8
