We take each number as x = 2x 3x 4x
(2x)³+(3x)³+(4x)³=33957
8x³+27x³+64x³=33957
99x³=33957
x³=33957÷99
=∛343
x=7
2x=2×7=14
3x=3×7=21
4x=4×7=28
=the three numbers are 14,21,28
Answer:
spinner green or blue
Step-by-step explanation:
Flipping a coin is 1/2 probability
Rolling a die and getting a number less than 4 is 1/2 probability
spinner green or blue is (4/6) = 2/3
Marbles is 1/2
Answer:
31√3
Step-by-step explanation:
48√3 + 45/√3 since the base is same we can add the terms up 93√3
➡ 93/√3 × √3/√3 = 93√3/3 ➡ 31√3
The variable Z is directly proportional to X
Z = kX (Where k is the constant of proportionality)
To find k
54 = k3
k = 54/3
k = 18
now find new Z
Z = 18X
Z = 18(12)
Z = 216
Generic exponential growth model: y = Ao[1+r]^t
In this case: r = 3.5% = 0.035
y = 2Ao .....[the double of the initial value]
Then: 2Ao =Ao (1 + 0.035)^t
(1.035)^t =2
Take logarithm to both sides
t ln(1.035) = ln(2)
t = ln(2) / ln(1.035) = 0.693 / 0.0344 = 20.15
Answer: 20.15 hours.
