Answer: 65.94
Step-by-step explanation:
Find the area of the middle circle.
3.14 x 2² = 12.56
Pretend the white area doesn't exist and find the area of the shaded region.
3.14 x 5² = 78.5
Then subtract.
78.5 - 12.56 = 65.94
Answer:
(-4,-1)
Step-by-step explanation:
Assuming the graph is the one shown in the attachment.
The forward sloping line has a slope of 1 and a y-intercept of 3.
The equation of this line is y=x+3
The horizontal line has a slope of 0 and y-intercept of -1.
It's equation is y=-1
The two lines intersect at (-4,-1)
Answer: a. 3.4t (miles)
b. 2.125 miles
c. t = 1.6 hours
Step-by-step explanation:
A) We will use the relation:
Distance = Speed × Time
Distance= 3.4 × t
= 3.4t (miles)
B) If t= 5/8
Distance d= 3.4 × 5/8
= 3.4 × 0.625
= 2.125 miles.
C) If the distance d= 5.44,
Time will be:
d= 3.4t, and we know that d=5.44
Therefore, 5.44 = 3.4t
t = 5.44/3.4
t = 1.6 hours
