In this question, the trail is 2940 miles long and Manfred is already hiking the 3/7 of the trail. You are asked how many miles he has a hike. Then to find it you just need to multiply the trail length with the ratio of hike/total trail. The calculation would be:

2940 miles * 3/7 = 1260 miles

Answer:

C. $Cos(28) = \frac{15}{17}$

Step-by-step explanation:

Recall: SOHCAHTOA

Thus,

$Cos(\theta) = \frac{Adjacent}{Hypotenuse}$

Reference angle = 28°

Adjacent = 15

Hypotenuse = 17

Plug in the values

$Cos(28) = \frac{15}{17}$

If D varies directly with t and D is 105 when t is 3, find D when t is 8.

Jet001 [13]

D varies directly with t means
d=kt

105=3k
divide both sids by 3
35=k

d=35t
when t=8
d=35(8)
d=280

Answer: 50 Books

Step-by-step explanation:

B = number of books in Ruben's collection BEFORE he bought new ones.

So 6 books were bought which increased his collection by 12%.

12% as a decimal would be 0.12..then we add the variable which represents the number of books, 0.12B.

So then we know 0.12=6

*We need to isolate the variable* So we would divide 0.12 on both sides. 0.12/0.12 and 0.12/6 which is 50.

Hope this helps! :)
