37. The students at Norton School were asked to name their favorite type of pet. Of the 430 students surveyed, 258 said that their favorite type of per
was a dog. Suppose that only 100 students were surveyed, with similar results, about how many students would say that a dog is their favorite
type of pet?

60 students

Step-by-step explanation:

So, in the first situation 430 students were surveyed and 258 said that their favourite pet was a dog. The second situation is 100 students and x said that their favourite pet was a dog. We are solving x.

430=258

100= x

Cross multiply

So that is

430 x X= 100x258

430x=25800

Divide both sides by 430

60 students

86 cm.

Step-by-step explanation:

If we add  1 more triangle to one in the picture we that:

If we  place 6 triangles together  the perimeter will be  6 + 2 = 6

for 8 triangles the perimeter is 10 .

For 84 the perimeter will be 86 cm.
