Answer:
Both ate 52 degrees
Step-by-step explanation:
You can find the measure of angle 5 by subtracting 128 from 180, which equals 52. From there you can deduct that angles 3 and 1 are congruent to 5, making them both 52 degrees.
Answer:
<h3>3/20*200</h3>
=5*3
=15%
the percentage of the number is 15%
Answer:
The answer would be 12.571428571 units or 12.57units.
Remark
The easiest way to do this is to find the radius of both spheres . That gives you the scale factor. The answer to the next two parts might surprise you.
Step one
Find the volume of the small sphere.
V = 4/3 pi r^3
V = 250 yards^3
pi = 3.14
r = ???
Sub and solve
250 = 4/3 pi * r^3 Multiply both sides by 3/4 to get rid of the fraction on the right.
250 * 3/4 = pi * r^3
187.5 = pi r^3 Divide by pi
187.5 / pi = r^3
59.71 = r^3 Take the cube root of both sides.
cube root (59.71) = cube root(r^3)
r = 3.91
Step 2
find the radius of the large sphere.
I'm just going to give you the answer. Follow the above steps to confirm it.
V = 686 cubic yards
pi = 3.14
r = ??
r = cube root (514.5/3.14)
r = 5.472
Step 3
Find the ratio
r_large/r_small = 5.472/3.91 = 1.3995
I'm going to leave the Area calculations to you
The area ratios should come to 1.96 (about)
The volume ratios should come to 1:2.74
Responder:
462 assentos
Explicação passo a passo:
Dado que :
Número da linha = 12; Número de assentos por fila = 16
Número de linhas = 15; número de assentos por fila = 18
Número total de assentos para as 12 filas:
12 * 16 = 192 assentos
Número total de assentos para as 18 filas:
15 * 18 = 270 assentos
Número total de assentos:
(192 + 270) = 462 assentos
