If CR = 2, RA = 3 , and BC = 10, find CS. 4 6 6 2/3 15

OlgaM077 [116]

Answer:

CS = 4

Step-by-step explanation:

From the figure below;

Triangle ABC is similar to triangle RSC

Therefore, the ratio of the corresponding sides in the two triangles is equal;

That is;

$\frac{AB}{RS}=\frac{AC}{RC}=\frac{BC}{SC}$

In this case, CR = 2 , RA = 3 and BC = 10 we are required to determine CS

But; $\frac{AC}{RC}=\frac{BC}{SC}$

AC=CR + RA

= 5

Assuming CS is y, then

$\frac{5}{2}=\frac{10}{y}$

$y=\frac{10(2)}{5} \\ = 4$

Therefore, CS is 4

The attendence at a water park varies directly as the temperature and invesely as the number of days of rain during the month. I

Margarita [4]

Let A be attendance, t the temperature and n the number of days. Then,
A $\alpha$ $\frac{t}{n}$
A=k $\frac{t}{n}$
Where k is a constant of proportionality;
If A=3200, T=88 and n=8, then k,
3200= $\frac{88k}{8}$
3200=11k
k= $\frac{3200}{11}$
Rewriting the equation and replacing the value of k,
A= $\frac{3200t}{11n}$
When t=92 and n=12
The A= $\frac{3200*92}{11*12}$
A= $\frac{294400}{132}$
A= 2231
