1) Answer is A (True). 5.7 can be written as fraction in which both numbers are whole finite numbers.
2) Answer is True. Explanation is same as for the previous question.
3) √24 is between 4 and 5. √16=4 and √25 is 5, therefore answer is D)
4) Answer is √136. 11²=121 and 12²=144 and the question doesn't include equal scenario which would look like "more or equal than 11 but less or equal than 12".
K = -6 because the four was multiplied to -2 on other side then the equation would be k - 2 = -8 then I add the two so that the k would be equal to -6
Can I plz have the crown
Answer: 1120
Step-by-step explanation:
Given: Size of the population in the study = 1200
Also they revealed that 12 out of every 180 frogs in the population have spots on their back.
Thus we have fraction
Hence, of total frogs have spots.
Now,
Therefore, 80 out of 1200 frogs in the population have spots.
Thus, the number of frogs in the population do not have spots = 1200-80=1120
Alrighty
squaer base so length=width, nice
v=lwh
but in this case, l=w, so replace l with w
V=w²h
and volume is 32000
32000=w²h
the amount of materials is the surface area
note that there is no top
so
SA=LW+2H(L+W)
L=W so
SA=W²+2H(2W)
SA=W²+4HW
alrighty
we gots
SA=W²+4HW and
32000=W²H
we want to minimize the square foottage
get rid of one of the variables
32000=W²H
solve for H
32000/W²=H
subsitute
SA=W²+4WH
SA=W²+4W(32000/W²)
SA=W²+128000/W
take derivitive to find the minimum
dSA/dW=2W-128000/W²
where does it equal 0?
0=2W-1280000/W²
128000/W²=2W
128000=2W³
64000=W³
40=W
so sub back
32000/W²=H
32000/(40)²=H
32000/(1600)=H
20=H
the box is 20cm height and the width and length are 40cm
