Answer:
420 calories.
Step-by-step explanation:
Jamie burned 480 calories on Monday. Then, she burned 7/8 of 480 calories.
480 * 7/8 = 420.
So, Jamie burned 420 calories on Tuesday. Dang gurl, that is a lot! xD
Hope this helps :D

Answer
62
5.3
65
5.8
2.5
Step-by-step explanation:
FOr the first one we have the opposite and adjacent side, so we'll use TOA
let x= angle
tan(x)=4.7/2.5
x=61.99 or 62
2.) for this one we can just use pathagoryeous thereom
2.5²+4.7²=c²
28.34=c²
c=5.323
3.) For this one we know that the angles in a traingle must add to 180
let x= missing angle
25+90+x=180
x=65
4.) For this one we have the adjacent side but need the hypotonouse
we will therefore use CAH
cos(25)=5.3/x
5.3/(cos(25))=x
x=5.8
5.) For this one we will just use the pathagoryeous to solve for the missing side
a²+5.3²=5.8²
a²=6.107
a=2.5
50% is just half of the price. you could also times the original price by 1/2 and get the same answer.
