Answer:
(a)h(g(133))
(b)f(j(6.82))
Step-by-step explanation:
(a)Area of a circle whose circumference is 133 cm.
Since g(C) represents the radius (in cm) of a circle whose circumference is C cm.
- The radius of the circle whose circumference is 133 cm = g(133)
h(r) represents the area of a circle whose radius is r cm.
Therefore, the area of a circle whose circumference is 133 cm is:
h(g(133))
(b)Circumference of a circle whose area is
j(A) represents the radius (in cm) of a circle whose area is A .
- The radius of the circle of area = j(6.82)
f(r) represents the circumference (in cm) of a circle whose radius is r cm.
Therefore:
- Circumference, f(r) = f(j(6.82))
The circumference of a circle whose area is =f(j(6.82))
Answer:

Answer:
Step-In total, the amount of money they will need to raise is:
= 450 + 325
= $775
by-step explanation:
They have 6 weeks to raise this money so the amount they have to raise per week is at least:
= 775/6
= $130
The candy bars cost $1 each. They will therefore have to sell a minimum of 130 candy bars each week to afford the trip.
Answer:
14
Step-by-step explanation:
The two triangles are similar
KN/KL = MN/JL
12/32 = (x+1)/(3x-2) multiply the fractions
36x-24 = 32x+32 export like terms to the same side
36x-32 = 32 + 24
4x = 56 divide both sides by 4
x = 14
