Step-by-step explanation:
Primero tienes que encontrar el número que te encuentres con 5 y con el mismo número lo haces con 7.
1st problem:
Use the Pythagorean theorem:
a^2+b^2=c^2
49+361=c^2
c^2=410
c=20.24
The answer is 20m
2nd problem:
First calculate the height using the Pythagorean theorem:
a^2+b^2=c^2
20^2+b^2=625 (i got 20 {radius} by half-ing the base edge length)
400+b^2=625
b^2=225
b=15
Next, solve for the volume:
V=a^2*h/3
V=40^2*15/3
V=1600*5
V=8000
The answer is the second choice or B.
total cost = membership +cost per class* number of classes
y = 275+5*x
Choice C
0.1875 you must divide 3 by 16 the numerator by the denominator
