Answer:
If `r` and `R` and the respective radii of the smaller and the bigger semi-circles then the area of the shaded portion in the given figure is: (FIGURE) `pir^2\ s qdotu n i t s` (b) `piR^2-pir^2\ s qdotu n i t s` (c) `piR^2+pir^2\ s qdotu n i t s` (d) `piR^2\ s qdotu n i t s`

Answer:
41 and 77
Step-by-step explanation:
x: his age the first time he went to space
y: his age the second time he went to space
the second time he went to space he was 5 years younger than twice the age when he went his first time, then:
y = 2x - 5
the sum of both ages is 118, then:
x + y = 118
If you replace y = 2x - 5 in x + y =118:
x + 2x - 5 = 118
3x = 123
x = 41
replacing x:
41 + y = 118
y = 118 - 41
y = 77
so when he was 77, he was 5 years younger than twice 41 ( 41*2 = 82 => 82 - 5 =77)
Porque menos por menos es más es una regla
Si multiplicas (-6)(-3) La respuesta es 18 es positivo porque se cumple la regla de menos por menos es más
REPASA
MENOS POR MENOS = MÁS
MÁS POR MÁS = MÁS
MAS POR MENOS = MENOS
MENOS POR MAS = MENOS
Answer:
If you meant for 1/2 and 3/4 to be simplified, then they are already in their reduced forms.
