Answer:
4/6
Step-by-step explanation:
a number which means "x" or u can name any variable u want
so the product of a number and four means
X×4
the increased by one or plus one
X×4+1
is at least 7
X(4)+1=7
4x+1=7
4x=7-1
4x=6
x=4/6
i guess so
lemme know if I'm right
Answer:
i) pi×4500 cm³
ii) pi×600 cm²
iii) 14 liters
Step-by-step explanation:
in general : the diameter is 30 cm, the radius is half of that (15 cm)
i)
the volume of a cylinder is base area times height.
Vc = pi×r²×h = pi×15²×20 = pi×225×20 = pi×4500 cm³
ii)
similar to volume, the side "mantle" area of the cylinder is the circumference of the base area times height.
surface area of the cylinder mantle is
Scm = 2×pi×r×h = 2×pi×15×20 = pi×30×20 = pi×600 cm²
iii)
for this we need now to do the multiplication with pi and then convert the cm³ to liters.
1 liter = a cube of 10 cm side length = 10×10×10 = 1000 cm³
pi×4500 = 14137.17 cm³ = 14.13717 liters or rounded 14 liters
Answer:
C. (0,b)
Step-by-step explanation:
Answer:
x=1 or x=16
Step-by-step explanation:
3/4x = 12 or 0.75x = 12
3/4x/3/4 = 12/3/4 or 0.75x/0.75 = 12/0.75
x=12/1 / 3/4
x= 4/4
x = 1 or x = 16
Plug all the point into your calculator. Not sure if you need it y=mx+b but the R for that is r= -1
