4.41 because .409 rounds up to .41,
Answer:
perimeter = 45 in.
area = 123.5 in.^2
Step-by-step explanation:
I assume this is a rectangle.
L = 13 in.
W = 9.5 in.
perimeter = 2(L + W) = 2(13 in. + 9.5 in.) = 2(22.5 in.) = 45 in.
area = LW = 13 in. * 9.5 in. = 123.5 in.^2
Answer:
A = 1.5 π in² ≈ 4.7 in²
Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 3² × 
= 9π ×
= 1.5π in²
≈ 4.7 in² ( to the nearest tenth )
<span>erry starts rowing at 2 pm from the west end of the lake, and Tao starts rowing from the east end of the lake at 2:05 pm.
------
Terry DATA:
rate = 60 meter/min ; time = x min ; distance = r*t = 60x meters
-----
Tao DATA:
rate = 40 meter/min ; time = x-5 min ; distance = r*t = 40(x-5) meters
--------------------------
If they always row directly towards each other at what time will the two meet?
------
Equation:
dist + dist = 2000 meters
60x + 40(x-5) = 2000
20x = 1800
x = 90 minutes
