Suppose astronomers built a 50-meter telescope. how much greater would its light-collecting area be than that of the 10-meter ke

drek231 [11]

Answer: Its light-collecting area would be 25 times greater than that of the 10-meter keck telescope.

Step-by-step explanation:

1. To solve this problem you must apply the formula for calculate the area of a circle, which is shown below:

$A=r^{2}\pi$

Where<em> r</em> is the radius of the circle.

2. The diameter of a circle is:

$D=\frac{r}{2}$

Where <em>r</em> is the radius of the circle.

3. Therefore, keeping this on mind, you have that the light-collecting area of a 50-meter keck telescope is:

$A_1=(\frac{50m}{2})^{2}\pi=1963,49m^{2}$

4. And the light-collecting area of a 10-meter keck telescope is:

$A_2=(\frac{10m}{2})^{2}\pi=78.53m^{2}$

5. Divide $A_1$ by $A_2$ , then:

$\frac{1963.49m^{2}}{78.53m^{2}}=25$

6. Therefore, its light-collecting area would be 25 times greater than that of the 10-meter keck telescope.

He coordinates below represent two linear equations.

fiasKO [112]

$\hbox{Line 1:}\\
m=\frac{5-4}{-3-0}\\
m=\frac{1}{-3}\\
m=-\frac{1}{3}\\\\
\hbox{Line 2:}\\
m=\frac{4-2}{0-6}\\
m=\frac{2}{-6}\\
m=-\frac{1}{3}$

Both lines have the same slope, which means they are parallel. They also pass through the same point $(0,4)$ . This means they're overlapping so there is infinitely many solutions.<span />

A theater company charges $9.50 per ticket for people of all age groups. If c represents the total number of children who bought

vlada-n [284]

C= number of children tickets
a= number of adult tickets

In the equation, $9.50 per ticket must be multiplied by each c and a in order to calculate the total.

($9.50 * c) + ($9.50 * a)

since each term has $9.50 in it, we can pull out the common $9.50 in each

$9.50(c + a)

this expression now means that we must multiply $9.50 by c and then multiply $9.50 by a (using the distributive property)

ANSWER: $9.50(c + a) - the second choice down

Hope this helps! :)
