Answer: 5 years

Step-by-step explanation:

Given : A town predicts that its population will double in $\dfrac{e^{\ln10}}{2\ln_e}$ years.

We know that $e^{\ln x}= x$

and the natural log of e = $\ln_e=1$

Then , the expression $\dfrac{e^{\ln10}}{2\ln_e}$ will becomes

$\dfrac{10}{2}=5$

Hence, The population of the town will be double in 5 years.

3. Formulate 900 lbs of a 35% CP ration using Soybean Meal (46% CP) and Oats (12% CP). How many pounds of soybean meal will be u

Anarel [89]

Answer:

The amount of Soyabean = 608.82 pounds.

The amount of Oats = 900-608.82 = 291.18 pounds.

Step-by-step explanation:

Given that the Soybean Meal has 46% CP and Oats has 12% CP.

The total amount of ration is 900 lbs of 35% CP.

Let x pounds of Soyabean has been used, so,

the amount of Oats = 900-x lbs.

The CP amount in 900 lbs mixture will be equal to the sum of CP amounts in x lbs Soyabean and 900-x lbs Oats, i.e

35% of 900 = 46% of x + 12% of (900-x)

$\Rightarrow \frac{35}{100}\times 900=\frac{46}{100}\times x+\frac{12}{100}\times (900-x)$

$\Rightarrow 35\times 900 = 46x + 12\times 900 - 12 x$

$\Rightarrow 34x= 900(35-12)$

$\Rightarrow x = (900\times 23)/34$

$\Rightarrow x = 608.82$ lbs.

So, the amount of Soyabean = 608.82 pounds.

The amount of Oats = 900-608.82 = 291.18 pounds.

Sedbober [7]

Answer: 1. $456\div2 =228$ 2. $538\div7=76.85$

Step-by-step explanation:

The given division problems :

$1.\ 456\div2$

$2.\ 538\div7$

By long division (see the attachment)

1. Divisor= 2

Dividend =456

Quotient = 228

Remainder =0

So, $456\div2 =228$

2. Divisor= 7

Dividend = 538

Quotient =76.85

so, $538\div7=76.85$

Please help asap 25 pts + brainliest to right/best answer

MakcuM [25]

Answer:

C is the answer.

Step-by-step explanation:

We know that the quadratic equations has to have the x² sign in the equation, so this is a quadratic term. 6x² is the quadratic term because of the x². That means the answer cannot be the second or last choice. The equation doesn't contain the value -12x², so the first answer choice cannot be right. This leaves the third answer choice.
