Answer: 1 bulb
Step-by-step explanation:
Using the proportion of flawed bulbs in the first scenario, you can get the number of flawed bulbs in the other bath.
First scenario total bulbs = 2 + 36 = 38
Proportion of flawed bulbs = 2/38 = 1/19
In a batch of 19, the flawed bulbs are;
= 1/19 * 19
= 1 bulb
Answer:
5
Step-by-step explanation:
The number of elements in set A is 5.
We can solve this problem by the rule of three.
1000 protons=10³ protons
1 proton------------------2.53*10⁻³⁷g
10³ protons---------- x
x=(10³ protons * 2.53*10⁻³⁷) / 1 proton=2.53*10⁻³⁷⁺³ protons=
=2.53*10⁻³⁴ protons
answer: 2.53*10⁻³⁴ protons
I believe this question logically tells us to find the value of w. The two equations are already equated. Since there is 1 unknown and 1 equation, the system is solvable. The solution is as follows:
5/(6w+21) = -1/3(2w - 9)
5/(6w+21) = -1/(6w - 27)
Cross multiplying the terms:
5(6w - 27) = -1(6w +21)
30w - 135 = -6w - 21
30w + 6w = -21 + 135 = 114
36w = 114
w = 114/36
w = 19/6 or 3.167
