You need to find the least common multiple of 8 and 6.

$8=2^3\\6=2\cdot3\\\\\text{lcm}(8,6)=2^3\cdot3=24$

Therefore, the answer is 24 days.

FCD=x+41, BCF=x+78, BCD=95. Find x

Lorico [155]

You'll set the two expressions equal to 95.
So 2x+119=95
Then 2x=-24
Finally x=-12

A 46 gram sample of a substance that is used to sterilize surgical instruments has a k-value of 0.1374. Find the substance's hal

mars1129 [50]

Answer:

$t=5.0days$

Step-by-step explanation:

Using the formula for the exponential decay that is $N=N_{0}e^{-kt}$ , we have N= $\frac{1}{2}{\times}46=23$ , $N_{0}=46$ and k=0.1374.

Thus, $N=N_{0}e^{-kt}$ becomes

$23=46{\times}e^{-0.1374t}$

$\frac{23}{46}=e^{-0.1374t}$

$\frac{1}{2}=e^{-0.1374t}$

Taking log on both sides, we get

$ln(\frac{1}{2})={-0.1374t}$

$t=\frac{ln\frac{1}{2}}{-0.1}$

$t=\frac{-0.6931}{-0.1374}$

$t=5.0days$

Express the calculation “four times as large as 124+645”

Effectus [21]

The calculation of the expression “four times as large as 124+645” end up in 1141.

<u>Step-by-step explanation:</u>

The question is asked to Express the calculation “four times as large as 124+645”.
The given statement can be written in the expression form to perform the calculations.

Here, the phrase 'four times' represents the multiplication of 4.

⇒ “four times as large as 124+645” = 4(124) + 645

So, the first step is to multiply 4 with 124.

⇒ 4 × 124

⇒ 496

The expression is now modified as “496+645"

We know that, the final result is the addition of the two numbers 496 and 645 which is calculated as

⇒ 496+645

⇒ 1141

Therefore, the calculation of the expression “four times as large as 124+645” end up in 1141.
