In a class of 30 students, 19 are studying French (F), 12 are studying Spanish (S) and 7 are studying both French and Spanish. H
Fiesta28 [93]

Answer: There are 14 students not taking any foreign languages.

Step-by-step explanation: Take the total number of  students and subtract it by the number of students who are taking each class. So you would get 19 for French, 12 for Spanish, and 7 for both. Then you would add those numbers up and get a total of 38. You would then do the same except subtract each total of students by 30 to find how many of the 30 are not taking each class or both. You would then get 11 for French, 18 for Spanish, and 23 for both. Add those numbers up and get 52. Then you would subtract 38 from 52 thus giving the final answer 14.

Help!!!!
joja [24]

Answer:

0.28 yr  

Step-by-step explanation:

To find the doubling time with continuous compounding, we should look at the formula:

FV = PVe^{rt}

FV = future value, and

PV = present value

If FV is twice the PV, we can calculate the doubling time, t

\begin{array}{rcl}2 & = & e^{rt}\\\ln 2 & = & rt\\t & = & \dfrac{\ln 2}{r} \\\end{array}

1. Samuel's doubling time

\begin{array}{rcl}t & = & \dfrac{\ln 2}{0.055}\\\\& = & \textbf{12.603 yr}\\\end{array}

2. Claire's doubling time

\begin{array}{rcl}t & = & \dfrac{\ln 2}{0.05625}\\\\& = & \textbf{12.323 yr}\\\end{array}

3. Samuel's doubling time vs Claire's

12.603 - 12.323 = 0.28 yr

It would take 0.28 yr longer for Samuel's money to double than Claire's.

A regular hexagon is shown below. Find the value of X
Varvara68 [4.7K]

Answer:

x=9

Step-by-step explanation:

The expression is for the interior angle of the hexagon; one interior angle is equal to (11x+21)^o.

Since an interior angle of a hexagon measures 120°, we have the equality

(11x+21)=120.

Now it is just a matter of solving for x:

11x=120-21\\\\11x=99\\\\x=\frac{99}{11} \\\\\boxed{x=9}

A construction company is analyzing which of its older projects need renovation. Building B was built two years before building
Black_prince [1.1K]

The inequality x²+6x +8 ≥ 195 represents the provided situation option (D) x²+ 6x +8 ≥ 195 is correct.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have building B was built two years before building C.

The age of C is represented by x

Age of Building B:  

b = x + 2

Building D was built two years before building B

Age of Building d= x+4

The product of the building B’s age and building D’s age is at least 195.

b×d ≥ 195

(x+ 2)(x+4) ≥ 195

After solving we get:

x²+ 6x +8 ≥ 195

Thus, the inequality x²+6x +8 ≥ 195 represents the provided situation option (D) x²+ 6x +8 ≥ 195 is correct.
