Answer:

D, or 190080

Step-by-step explanation:

First, we can convert 3 miles into feet. 5280*3 is equal to 15840. Then, we need to convert to inches. 15840*12 is 190080, or choice D.

Can someone tell me if my answer to this problem is correct, please? And if it isn't how do you solve it?

Mrac [35]

Answer:

Height of tree= 13.8m

Step-by-step explanation:

When finding the value of a in your working, I suggest to leave the answer to 5 significant figures so that your final answer is more accurate. The value of a should be 26.048m to 5 s.f.

Then multiplying 26.048 with sin 32° would give you 13.8m too when rounded off to 3 significant figures :)

I have attached my working too.

Sonny substituted 5 for x in the proportion 16/x=48/15 and cross multiplied to get 240=240. Why is this?

Mashutka [201]

Because 16/5 and 48/15 are equivalent fractions
