Answer:
m= -5
Step-by-step explanation:
This is very simple.
Basically, the formula for a slope intersect form is this:
y= mx+b
Where y is the y value, x is the x value, b is the y intercept, and m is the slope.
Because m is -5 in this equation, that means the slope is -5.
Percentage left = 100-(12+25) = 63%
63% = (60+210+108)
63% = 378
1% = 378/63 = 6
no. of students biking = 25% * 6
= 150 students
Divide 60 by 3 okay .......
Answer:
A = 7,241.2454026112 square mm.
or exact : A = 2,304.96*π sq mm
Step-by-step explanation:
Cylinder formula: A = π* r^2 + 2 *π * r* h + π*r^2
is the surface area.
d = 2r = 39.2 mm
h = 39.2 mm
r = 19.6 mm
A = π* r^2 + 2 *π * r* h + π*r^2
A = 2* π* (19.6)^2 + 2π (19.6)*(39.2)
A = 2,413.748467537 + 4,827.496935
A = 7,241.2454026112 square mm.
or
A = 2*pi* (768.32 + 384.16)
A = 2*1,152.48* pi
A = 2,304.96*π sq mm
