Hope this helps.
As was the case in your previous question, this problem involves setting two ratios equal to each other. We call such an equation a proportion.
16 miles = x miles
(1/2) inch 2 3/4 inches
x = (11/4) * 16 = (11/4) * 2 * 16 = 88 miles
(1/2)
Answer:
15x^2-14x-4
Step-by-step explanation:
(8x^2 * x-7x+2)+(7x^2 -7x-6)
you take out the parentheses
you add the common ones so -7x+-7x= -14x
8x^2 +7x^2 = 15x^2
and 2-6= -4
so in total it's 15x^2-14x-4
Answer:
83.96 (approximately)
Step-by-step explanation:
I am not completely sure what the problem is asking, just like the last one, but I believe that you are just supposed to take the inverse of cosine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then cosine. You use the inverse of cosine when two sides are given, but you are not given the angle.
It should look like:
, which is approximately 83.96.
Hopefully this is right, if not, please let me know. Good luck.
