Softa [21]

Answer:

140

Step-by-step explanation:

Given:

In the Stone Ridge apartment complex 35% of the apartments have one bedroom.

If there are 49 one bedroom apartments.

Question asked:

What is the total number of apartments at Stone ridge ?

Solution:

Let total number of apartments at Stone ridge = $x$

Now according to question:

35% of the total apartments having one bedroom = 49

$35\%\ of x = 49$

$\frac{35}{100}\times x = 49$

$\frac{35x}{100} = 49$

By cross multiplication:

$35x = 49\times100\\35x= 4900\\$

By dividing both sides by 35

$\frac{35x}{35} = \frac{4900}{35} \\x = 140$

Therefore, total number of apartments at Stone ridge is 140

Answer:

$x=\boxed{6.6}$

$\overline{\sf DE}=\boxed{13.2}\:\:\sf units$

Step-by-step explanation:

Geometric Mean Theorem - Altitude Rule

The altitude drawn from the vertex of the right angle perpendicular to the hypotenuse separates the hypotenuse into two segments. The ratio of one segment to the altitude is equal to the ratio of the altitude to the other segment:

$\sf \dfrac{segment\:1}{altitude}=\dfrac{altitude}{segment\:2}$

From inspection of the given diagram:

altitude = FD = 9
segment 1 = CD = 5
segment 2 = DE = $2x+3$

$\begin{aligned}\sf \dfrac{segment\:1}{altitude} & = \sf \dfrac{altitude}{segment\:2}\\\\\implies \dfrac{5}{9} & = \dfrac{9}{2x+3}\\\\5(2x+3) & = 81\\\\10x+15 & = 81\\\\10x & = 66\\\\ \implies x & = 6.6\end{aligned}$

Substitute the found value of x into the expression for DE:

$\begin{aligned}\sf \overline{DE} & = 2x+3\\\implies \sf \overline{DE} & = 2(6.6)+3\\& = 13.2+3\\& =16.2\:\: \sf units\end{aligned}$

How to solve 2x+5 if x equals 7

tatuchka [14]

Answer:

2(7) + 5 = 19

Step-by-step explanation:

Okay, so do it like this:

2x+5

x = 7

2(7) + 5

2(7) = 2 x 7

2 x 7 = 14

Now it's 14 + 5

14 + 5 = 19

Your answer is 2(7) + 5 = 19

Which statement best describes the use of a stimulation to predict the probability that two randomly chosen people will both hav

777dan777 [17]

Answer:

The answer is "The Last choice".

Step-by-step explanation:

Please find the complete question in the attached file.

It is the phrase that perfectly represents the usage of a simulation for an estimate of the likelihood of the birthday of 2 randomly chosen persons on a Monday.

In a week there are 7 days, so seven choices are available, and just one Monday. Therefore, it is probable that $\frac{1}{7}$ will occur on a Monday to a birthday individual.

The first person will have a probability $\frac{1}{7}$ .

The second person also has a probability $\frac{1}{7}$ .
