First convert 6 feet to inches.
12x6=72
Then write a proportion!
8/72=4/x
Cross multiply!
72x4=8 x x
288=8x
Divide by 8 on both sides.
x=36 inches. or 3 feet
Answer is 3 feet or 36 inches
Given:
Principal = 2,500
rate = 3.5%
term = 6 years
Simple interest = Pricipal x rate x term
S.I. = 2500 x 3.5% x 6
= 87.50 x 6
S.I. = 525.00 CHOICE C.
Suzanne will earn an interest of $87.50 per year and a total of $525 interest at the end of 6 years.
Answer:
x = -5
Step-by-step explanation:
You are often told to start a problem like this by clearing fractions. Multiply the equation by the least common denominator of the fractions. Here, that value is 6.
4x -3 = 2 +5x . . . . multiply the equation by 6
-5 = x . . . . . . . . . . . add -2-4x to both sides
The solution is x = -5.
_____
If you're comfortable with arithmetic using fractions, you can "cut to the chase." Subtract 2/3x+1/3 from both sides:
(2/3x -1/2) -(2/3x +1/3) = (1/3 +5/6x) -(2/3x +1/3)
-1/2 -1/3 = 5/6x -2/3x . . . . simplify a little
-5/6 = 1/6x . . . . . . . . . . . . .simplify more
-5 = x . . . . . . multiply by 6
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
Answer:
B - 16466
C - 13362
total value - 35170
Step-by-step explanation:
to find B add 11124 to 5342 (11124+5342=16466)
to find C subtract 3104 from 16466 (16466-3104=13362)
total value - add them all together
