Answer:

$\overline {AT} = 6$ is the correct answer.

Step-by-step explanation:

$\overline {TR}$ bisects $\overline {AC}$ at $R$ , so, $\overline {AT}=\overline{TC}$

Sandra's printer can print 5 pages in 2/3 of a minute (40s). Show different ways to determine how many pages her printer can pri

Ne4ueva [31]

Answer:

$7\frac{1}{2}$ pages

Step-by-step explanation:

Method 1: Working with minutes

Let us assume that, Sandra's printer can print x pages in 1 minute.

Then we can write the equation:

$x:1=5:\frac{2}{3}$

We can rewrite the ratios as a fraction.

$\frac{x}{1}=\frac{5}{\frac{2}{3}}$

This simplifies to

$x=\frac{15}{2}$

$x=7\frac{1}{2}$

Method 2: Working with seconds

If 5 pages corresponds to 40 seconds, then we can write: $5:40$

Let y corresponds to 60 seconds (1 minutes).

Then:

$y:60=5:40$

We rewrite as fraction:

$\frac{y}{60}=\frac{5}{40}$

Multiply both sides by:

$y=\frac{5}{40}\times 60$

$y=\frac{300}{40}$

$y=\frac{15}{2}$

$y=7\frac{1}{2}$

if a duck is quacking upside down and I drive my car into the refrigerator then why is there an octopus on my ceiling?

Amanda [17]

Since the ducks quack in the reverse position of upright is louder than normal, it obstructs your driving causing you to drive into a refrigerator. the octopus had always been there

the sequence {a_n} is defined by a_1= 1 and a_(n+1) = 1/2( a_n+ (4/a_n) ) for >=1. Assuming that {a_n} converges, find its li

katen-ka-za [31]

$a_{n+1}=\dfrac{a_n+\frac4{a_n}}2$

Assuming convergence of the sequence, we have $a_n\to L$ for some limit $L$ as $n\to\infty$ . This also means $a_{n+1}\to L$ . So in the above equation, we can substitute and solve for $L$ :

$L=\dfrac{L+\frac4L}2$

$\implies2L^2=L^2+4$

$\implies L^2=4\implies L=\pm2$

The limit can only be one of these values; otherwise, the sequence would be divergent. To decide which one is correct, we can observe that the sequence is strictly positive. So $L=2$ .
