For 9, the only thing similar IS the slope of the hypotenuse because the triangles are along the same line. Unless they're asking for the equation of the line, then that's just using the point slope equation which is:

y = - x + 5

For 10, just multiply 4 and 5 by 4 to get 16 and 20. Then multiply 16 and 20 to get 320.

There are 870 boys and 800 girls in a school

Answer:

1060

Step-by-step explanation:

Given:

No. of boys = 870

No. of girls = 800

Probability that a boy chosen studies Spanish = $\dfrac{2}{3}$

Probability that a girl chosen studies Spanish = $\dfrac{3}{5}$

the number of boys in the school who study Spanish :

$\dfrac{2}{3}\times 870=290\times 2=580$

the number of girls in the school who study Spanish :

$\dfrac{3}{5}\times 800 \\=3\times 160\\\\=480$

Therefore, total number of students who study Spanish would be :

480+580=1060
