Answer: 30
Step-by-step explanation: when you look at the x value of 9, the y value on the best fit line would be 30
Answer:
She can make 13 flags
Step-by-step explanation:
40 5/6 divided by 3 1/8
245/6 divided by 25/8
245/6 x 8/25
Use cancellation for a more simplified result
49/6 x 8/5
49/3 x 4/5 = 196/15 = 13 1/15
She can make 13 flags
Answer:
i think it is 141.4
Step-by-step explanation:
Answer:
1)m=9ft and n=10ft
2) p=10cm and r=18cm
3) s=4mi and t=8mi
Step-by-step explanation:
1)
Finding 3rd angle:
F= 180-(90+60)
= 180-150
=30
Now using law of sines to find sides m and n
m/sinD = 5/sinF
m= sin60(5/sin30)
= 8.66
= 9
n/sinE= 5/sin30
n= sin90(5/sin30)
= 10
hence m=9ft and n=10ft
2)
Finding 3rd angle:
F= 180-(90+60)
= 180-150
=30
Now using law of sines to find sides p and r
p/sinF = 21/sinE
p= sin30(21/sin90)
= 10.5
= 10
r/sinD= 21/sin90
r= sin60(21/sin90)
= 18.18
=18
hence p=10cm and r=18cm
3)
Finding 3rd angle:
F= 180-(90+60)
= 180-150
=30
Now using law of sines to find sides s and t
s/sinF = 3√6/sinD
s= sin30(3√6/sin60)
= 4.24
= 4
t/sinE= 3√6/sinD
t= sin90(3√6/sin60)
= 8.48
= 8
hence s=4mi and t=8mi !
