Firstly, since it is given that Xavier doesn't wait at all, in order for them to meet, Yolanda must arrive before Xavier. This in mathematical terms can be expressed as

$Y \leq X$

Secondly, Yolanda will wait for only 45 minutes, So Xavier must arrive before that, i.e

$X \leq Y+45$

Combining both conditions, we obtain

$Y \leq X \leq Y+45$

If $f(x)$ and $g(y)$ be the density functions for Xavier and Yolanda respectively, the probability of meeting is given by,

$\int_{0}^{10} \int_{y}^{y+45} f(x)g(y)dxdy$ .

The lenngths of the sides of the triangle are in the extended ratio 8:9:10. The primeter of the triangle is 108 cm.What are the

hjlf

Answer:

Side known in ratio as 8: 32

Side known in ratio as 9: 36

Side known in ration as 10: 40

Step-by-step explanation:

We can add all the numbers in the ration to form the sum of all the sides, or also equal to perimeter. 8+9+10 equals 27.

So we can write 27x=108

x=4. Multiply 4 to 8, then 9, then 10. You get 32, 36, 40

Hope this helped, Have a Great Day!!

I'm thinking its 7 cm because there is a side the same length right above it.
