The student-to-faculty ratio at a small collage is 17:3. The total number of students and faculty is 740. How many faculty membe

kozerog [31]

There are 111 faculty members at the college and 629 students at the college.

Step-by-step explanation:

Given,

The student to faculty ratio = 17:3

Total number of 740.

Let,

x be the original number.

Number of students = 17x

Number of faculty = 3x

Number of students + Number of faculty = 740

$17x+3x=740\\20x=740$

Dividing both sides by 20

$\frac{20x}{20}=\frac{740}{20}\\x=37$

Number of students = 17x = 17*37 = 629

Number of faculty = 3x = 3*37 = 111

There are 111 faculty members at the college and 629 students at the college.

Select all TRUE statements : A - Dilation always increase the length of shapes or line segments. B- Dilations of an angle are co

timurjin [86]

Hi!

A is FALSE - If you shrink a shape, it is not increased a shape, yet it is still dilating.

B is TRUE - When you dilate an angle, you're really just shortening or lengthening the sides, but the angle isn't changing.

C is FALSE - Explained above.

D is FALSE - Two triangles that are congruent are exactly the same, therefore if you dilate a triangle, you are changing the size so they are not the same.

E is TRUE - Similar shapes are always the same except for their size. When you dilate a shape, you only change the size, therefore they are equal in every other way and they are similar.

Figure out the two- step equation please i NEED HELLLP! -5c - 15 = -35

mariarad [96]

Answer:

c=4

Step-by-step explanation:

-5c - 15 = -35

Add 15 to each side

-5c - 15+15 = -35+15

-5c = -20

Divide each side by -5

-5c/-5 = -20/-5

c = 4

Determine whether the series is absolutely convergent 1-(1*3/3! (1*3*5/5!-（3*5*7）

DENIUS [597]

It's not clear what your series is, so I'm going to take a wild guess on what it is you mean:

$1-\dfrac{1\times3}{3!}+\dfrac{1\times3\times5}{5!}-\dfrac{1\times3\times5\times7}{7!}+\cdots$
$=\displaystyle\sum_{n=1}^\infty\frac{(-1)^{n-1}}{(2n-1)!}\prod_{k=1}^n(2k-1)$

For the sum to be absolute convergent, the sum of the absolute value of the summand must converge, so you are really examining the convergence of

$\displaystyle\sum_{n=1}^\infty\frac1{(2n-1)!}\prod_{k=1}^n(2k-1)$

This is easily checked with the ratio test:

$\displaystyle\lim_{n\to\infty}\left|\frac{\displaystyle\dfrac1{(2(n+1)-1)!}\prod_{k=1}^{n+1}(2k-1)}{\displaystyle\dfrac1{(2n-1)!}\prod_{k=1}^n(2k-1)}\right|=\lim_{n\to\infty}\left|\frac{\dfrac{1\times3\times5\times\cdots\times(2n-1)\times(2n+1)}{(2n+1)!}}{\dfrac{1\times3\times5\times\cdots\times(2n-1)}{(2n-1)!}}\right|$
$\displaystyle=\lim_{n\to\infty}\left|\frac{\dfrac{2n+1}{(2n+1)(2n)}}{\dfrac11}\right|=\lim_{n\to\infty}\dfrac1{2n}=0$

Since $\sum|a_n|$ converges by the ratio test, the series $\sum a_n$ converges absolutely.
