Answer:
y =8
Step-by-step explanation:
1/2y+2/5=4 2/5
Subtract 2/5 from each side
1/2y+2/5-2/5=4 2/5-2/5
1/2 y = 4
Multiply each side by 2
1/2y *2 = 4*2
y = 8
The error is that 9 shouldnt be written as nine it should be written as 3x3 or 3^2. So the answer should be 2^3 x 3^2 because 9 can be divided into even more prime factors of 72.
Answer:
V=250.3cm³
Step-by-step explanation:
V=1/3 × π x 5.4² cm x 8.2cm
V= 1/3 x π x 5.4² cm x 8.2cm
V= 1/3 x π x 29.16 cm x 8.2cm
V=250.39cm³
V=250.3cm³
Answer:
-1
Step-by-step explanation:
Rewrite i 14 as ( i 4 ) 3 × i 2 . If i = √ − 1 , then i 2 = − 1 .
From here ( i 2 ) 2 = ( − 1 ) 2 , so i 4 = 1 . If i 4 = 1 ,
then we can say that: i 14 = ( 1 ) 3 × i 2 = i 2 = − 1
