Jason: 5/7
Sara: 4/5
Think of it this way: if the total track is a mile, and Jason runs 5/7 of it, he has run 5/7 of a mile. Then Sara runs 4/5 OF 5/7, with "of" meaning "times," so she runs 4/5 x 5/7, which gives you 20/35, which simplifies to 4/7. You can also think of Sara's distance as 80 percent of Jason's. If she runs "80 percent of the sevenths that Jason ran," that means she ran 4 out of his 5 sevenths.
Answer:
98°
142°
83°
97°
Step-by-step explanation:
m(arc)JL = 2 × 49° = 98°
m(arc)MJ = 360° - 120° - 98° = 142°
m<KJM = (120° + 46°)/2 = 83°
m<KLM = (360° - 120° - 46°)/2 = 97°
Answer:
I think its 46, hope this helps!!!
Answer:
20:5
Step-by-step explanation:
find how many parts (5)
25/5=5 (1 part)
5*4=20
5*1=5
First, find R angle at TRS = 180-(10x+13)
then you know that total angles of a triangle is 180 so
TRS+RST+STR
180-(10x+13) + 8x+1 + 34 = 180
180-10x-13+8x+1+34 = 180
-13+1+34 = 10x-8x
22 = 2x
then x = 11
