Answer:10
Step-by-step explanation:
160cm3
2/5 - 1/4 = 8/20 - 5/20 = 3/20
(3/20)t = 24
t = 160
You literally need to apply the formula
where 
is the mass and 
is the speed
Answer:
4^y = x + 3
2^y = x + 2
Step-by-step explanation:
log_4(x + 3 ) = log_2 (2 + x )
log_4( x + 3 ) = y
log_2 (2 + x ) = y
4^y = x + 3
2^y = x + 2
Answer:
9
Step-by-step explanation:
To calculate c from the first right angle triangle,
C2 = 36 + 16
C = sqrt(52)
To calculate a from the bigger right angle triangle,
B2 + 52 = (a + 4)2
B2 - a2 = -36 + 8a
A2 + 36 = B2
Solving both by elimination,
A = 72/8
=9
