Answer:
y = 10
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
Answer:
the answer is 3
Step-by-step explanation:
First change the whole number (3) to quaters or fraction
3x 
= 
Now, add
+ = 
Since, we have the same common denominator
now divide
14÷4 =3.5 = 3
Therefore, there are 3 of 3/4 with a remainder of in 3 .
The experimental units in this experiment are the 10 plants in group 2.
The experimental unit is a term used in science to refer to an individual or group of objects that are initially equivalent and then undergo experimental processes.
According to the above, the experimental unit of this experiment is the group 2 of plants because these are the plants that are going to be put into experimentation with a new fertilizer.
Then, the answer is D, because it refers to the experimental unit corresponding to this experiment.

Answer:
breadth = 12
length = 36
Step-by-step explanation:
let the breadth be 'x'
length = 3x
p = 2l + 2b
96 = 2(3x) + 2(x)
x = 12
