A=4-3b
subtract 4 from both sides
a-4=-3b
divide by -3 for both sides
(a-4)/-3 = b
For question one, you would need to use the formula pi r ^2. So first you have 4.5, which is your radius(stands for r). Then you square it, which is 20.25. Then, you multiply 20.25 with pi. Then for circumference, you do 2 x pi x the radius which is 4.5. So for area, you get 63.62. Then for circumference you get 28.27.
For question 2, it is basically the same steps but instead you a diameter, not a radius. To get the radius, divide by 2, which the radius will be 6. Then from there, the radius is 6, and you solve the question.
Answer:
40.00
Step-by-step explanation:
una sandia 10.00
un banano 2.00
un aguacate 3.00 (porque una docena equivale 12 artículos; 36/12 es 3)
una sandía 10.00
una docena de bananos 12(2.00) = 24.00
dos aguacates 2(3.00) = 6.00
10.00 +24.00 +6.00
=40.00
Answer:
permeant
Step-by-step explanation:
Stroking with one pole of a permanent magnet works because it aligns the atoms in the nail to line up in the same polar direction, giving the nail a north and a south magnetic pole.
