Here,
let the longer piece be y and shorter piece be x
now,
according to the question,
x+y=19 .............................equation (1)
y=4+2x ...............................equation (2)
from equation 1
x+y=19
x+4+2x=19 substituting the value of y from equation 2
3x=19-4
x=(19-4)/3
x=5
now
substituting value of x in equation (2)
y=4+2(5)
y=4+10
y=14
so , the longer piece is 14 foot and the shorter piece is 5 foot
Answer:
Cassava = ⅓ or 33.333%
Maize = ⅔x⅔ = 44.444%
total so far =77.777%
Remaining vegetable area =(100–77.777%) = 22.222%
If remaining area vegetables = 22.222% = 10 acres
Maize = ⅔x⅔ = 44.444% or 20 acres
Cassava = ⅓ or 33.333% or 15 acres
Total land area = 45 acres.
Step-by-step explanation:
1 =25 times 1+8=33
2=25 times 2+8=58
3=25 times 3+8=83
4=25 times 4+8=108
5=25 times 5+8=133
B
10= 25times 10+8=258
C
233=25 times x+8
233=25x+8
233-8=25x
225=25x
225/25=25x/25
9=x
there are 9 classes.
how does it feel? ti isnt cool to mess others up.
Answer: 2. It is likely that a confounding variable could be a contributing explanation for the difference between these two groups.
3. This is an observational study, not an experiment.
Step-by-step explanation:
Based on the information given, the statement that's true include:
• It is likely that a confounding variable could be a contributing explanation for the difference between these two groups.
• This is an observational study, not an experiment.
It is an observational study as the researcher observed just observed the scenarios without him trying to change the people that are being exposed to it or controlling it.
Therefore, the correct options are II and III only.
