On a particular Saturday, 60% of the visitors to an art museum were students. If 144 visited the museum, how many total visitors

Bad White [126]

Answer:

240 visitors

Step-by-step explanation:

We are given the following in the question:

Percentage of visitors that are student to art museum = 60%

Total number of students to museum = 144

We have to find the total number of visitors to the museum.

Let x be the total number of visitors to the museum.

Thus, we can write the equation:

$60\%\times x = 144\\\\\dfrac{60}{100}\times x = 144\\\\\Rightarrow x = 144\times \dfrac{100}{60}\\\\\Rightarrow x = 240$

Thus, there were 240 visitors to the art museum on that day.

Water flows into a tank according to the rate F(t) = t+6/1+t, and at the same time empties out at the rate E(t) = ln(t+2)/t+1, w

Bas_tet [7]

Answer:

12.29minutes

Step-by-step explanation:

The net flow rate = flow in - flow out = F(t) - E(t) = t+6/1+t - ln(t+2)/t+1 = [(t + 6) - ln(t+2)]/(t+1)

So, the amount of water present in the tank at time, t is A = net flow rate × time = [(t + 6) - ln(t+2)]/(t+1) × t = t[(t + 6) - ln(t+2)]/(t+1)

At t = 10 minutes,

A = t[(t + 6) - ln(t+2)]/(t+1)

A = 10[(10 + 6) - ln(10+2)]/(10+1)

A = 10[16 - ln12]/11

A = 10[16 - 2.485]/11

A = 10[13.515]/11

A = 135.15/11

A = 12.29 minutes

I need helpWith this problemFor my grandson. I did get some help but need more. Thank you!

Step 1:

Percent is part of 100.

Step 2

First part:

60 units split into 80% and 20%

$\begin{gathered} 80\text{ \% of 60 units = }\frac{80}{100}\text{ }\times60\text{ = 48} \\ 20\text{ \% = 12} \end{gathered}$

Second part

12 units = 40 %

$\begin{gathered} 40\text{ \% = 12 units } \\ 60\text{ \% = }\frac{60\times12}{40}\text{ = 18 units} \end{gathered}$

Third part

30 % = 18 units

$\begin{gathered} 30\text{ \% = 18 units} \\ 70\text{ \% = }\frac{18\text{ }\times\text{ 70}}{30}\text{ = 42 units} \end{gathered}$

Fourth part

75 % = 42 units

$\begin{gathered} 75\text{ \% = 42 units} \\ 25\text{ \% = }\frac{25\text{ }\times\text{ 42}}{75}\text{ = 14 units} \end{gathered}$

Final answer

14 + 42 = 56 units

The length of the bottom diagram = 56 units
