the correct question is
<span>Two cones have a radius of 2 cm. The height of one cone is 8 cm. The other cone is
1/4 that height. Which of these statements is NOT true?
</span>
the statements in the attached figurewe know that
r=2 cm
h1=8 cm
h2=(1/4)*8=2 cm
[Volume of cone 1]=(π*r²*h)/3--------> (π*2²*8)/3= 33.49 cm³
[Volume of cone 2]=(π*r²*h)/3--------> (π*2²*2)/3---------> 8π/3= 8.37 cm³
<span>Statements A)
</span><span>The volume of the smaller cone is (1/4)(1/3π • 2 • 2 • 8) cm3---------> is true
</span>
Statements B)
<span>The volume of the smaller cone is (1/3)(4π • 2) cm3.-----------> is true
</span>
Statements C)
The volume of the smaller cone is (8/3)π cm3. -----------> is true
Statements D)
The volume of the smaller cone cannot be determined because its height is unknown-----------> is not true
the answer is the Statements D)The volume of the smaller cone cannot be determined because its height is unknown-----------> is not true

Answer:
the that minimizes the function is (80, 50) for which C = 9050
Step-by-step explanation:
(0, 160). (55, 70). (80, 50). (170, 0)..... available pairs missing out in the question
Step 1: to get the pair that minimizes the objective function C = 60x + 85y, we plug in each pair and work out the minimum value of C.
(0, 160): C = (60*0) + (85*160) = 13600
(55, 70): C = (60*55 + (85*70) = 9250
(80, 50): C = (60*80) + (85*50) = 9050
(170, 0): C = (60*170) + (85*0) = 10200
Hence the minimum value of C occur at (80, 50)
Answer:
8
Step-by-step explanation:
6^7 : 6^6 = 6^(7-6) = 6^1 = 6
3^3 : 3^4 = 3^(3-4) = 3^-1 = 1/3
6* 1/3 = 2
2^3 = 8
Answer:
51
Step-by-step explanation:
Given parameters:
Number of heads = 30 heads
Number of legs = 84 legs
Unknown:
Number of chickens and pigs = ?
Solution:
Since a chicken has one head, the number of chicken is the same as the number of heads;
Number of chicken = 30
A pig has 4 legs,
Number of pigs = = 21pigs
Total number of pigs and chickens = 30chickens + 21 pigs = 51
