Answer: point b
Step-by-step explanation:
eatch mark on the line is 0.1, b is right behind the 8.6 mark in the middle making it 8.65
Answer:
x = days he reads for 4.5 hours = 1 day
y = days he reads for 3.5 hours = 6 days
Step-by-step explanation:
Let
x = days he reads for 4.5 hours
y = days he reads for 3.5 hours
x + y = 7 (1)
4.5x + 3.5y = 25.5 (2)
From (1)
x = 7 - y
Substitute x = 7 - y into (2)
4.5x + 3.5y = 25.5 (2)
4.5(7 - y) + 3.5y = 25.5
31.5 - 4.5y + 3.5y = 25.5
- 4.5y + 3.5y = 25.5 - 31.5
-y = -6
y = 6
Substitute y = 6 into (1)
x + y = 7 (1)
x + 6 = 7
x = 7 - 6
x = 1
x = days he reads for 4.5 hours = 1 day
y = days he reads for 3.5 hours = 6 days
Answer:

Answer:
Step-by-step explanation:
Answer:
Q1: 48ft
Q2: 14.6
Step-by-step explanation:
Question 1:
Since the two triangles are similar (Angle - Side - Angle):
30/x = 50/80
x= 30(80/50)
=48
Question 2:
sin(55deg) = 12/x
12/sin(55) = x
x=14.6 (3 s.f.)
