Answer:
1/4
Step-by-step explanation:
Answer: y=-6
Step-by-step explanation:
y = -4 when x = 1
find y when x = 3
y=-4 x=1
y=-5 x=2
y=-6 x=3
im not sure if this is right so I’m sorry
Answer : The grain of sand is 50 times greater than the phytoplankton.
Step-by-step explanation :
As we are given that:
Size of phytoplankton = 2 × 10⁻⁶ in
Size of sand grain = 1 × 10⁻⁴ in
Now we have to determine how many times longer the grain of sand is than the phytoplankton.
We are dividing the sand grain size by the phytoplankton size.
This can be done by equating it as follows:


Therefore, the grain of sand is 50 times greater than the phytoplankton.
Answers:
x = 19/2 = 9.5
y = 44/3 = 14.667
The decimal value of y is approximate

The triangles are similar. So the corresponding sides form a proportion
KM/KJ = LN/LJ
(x-2)/5 = 12/8
8(x-2) = 5*12
8x-16 = 60
8x = 60+16
8x = 76
x = 76/8
x = 19/2
x = 9.5
Similarly,
MN/KL = LN/LJ
22/y = 12/8
22*8 = 12y
12y = 176
y = 176/12
y = 44/3
y = 14.667 (value is approximate)
