Answer:
see explanation
Step-by-step explanation:
given that V is directly proportional to u and inversely proportional to f , then the equation relating them is
V = 
← k is the constant of proportion
(a)
to find k use the condition when u = 1 and f = 3 , V = 
, then
= 
( cross- multiply )
6k = 3 ( divide both sides by 6 )
k = 
= 
V = 
← equation of proportion
(b)
when f = 4 and V = 1 
= 
, then
= 
= 
( cross- multiply )
4u = 40 ( divide both sides by 4 )
u = 10
Answer:
thw answer is c if you count the blocks
The answer will be 32 + 12
Answer:
C
Step-by-step explanation:
ok so sam started with 0 and got -9 then he got 12 then the next known number is -8 so those three numbers together are -5 and the end result was -1 so -1 minus -5 is -4 therefore the anser is C

Answer:
AB = 4
∠E = 30°
Step-by-step explanation:
Side AD is 4 times the length of corresponding side EH, so we expect side AB to be 4 times the length of side EF.
AB = 4·EF = 4·1
AB = 4
__
Angle E will have the same measure as corresponding angle A.
angle E = 30°
