If the number of pounds of chicken is represented by c, then the number of the pounds of beef is 12 - c. The equation that best represent the given conditions above based on the total amount that Jenny spent is,
1.9c + 4.3(12 - c) = 34.8
The answer is letter D.
Let x = one of the side lengths of the base.
Then area of the base = x². So volume of the base = x²h.
That gives us x²h = 20. Solving for x, we get x = √(20/h²).
Glass is needed to cover the sides of the aquarium. There are 4 sides and 1 base. Area of a side = hx = h√(20/h²). Area of the base = x² = 20/h. Total area of glass = h√(20/h²) + 20/h. So the cost for glass = 8 * [h√(20/h²) + 20/h] = 8 h√(20/h²) + 160/h.
Metal frame is needed along the edges of the sides. There are 4 edges on the top, 4 edges in the bottom and 4 vertical edges. So the total length of metal frame = 4x + 4x + 4h = 8 √(20/h²) + 4h. Then the cost for metal frame = 7 * [8 √(20/h²) + 4h] = 56 √(20/h²) + 28h.
So the total cost = 8 h√(20/h²) + 160/h + 56 √(20/h²) + 28h
1.)x+5;x=3
(3) + 5
8
2.)7x;x=-5
7(-5)
35
3.)y=1-2x;x=9
y = 1 - 2(9)
y = 1 - 18
y = -17
4.)y=3x+2;x=0.5
y = 3(0.5) + 2
y = 1.5 + 2
y = 3.5
5.)y=2x^3;x=3
y = 2(3^3)
y = 2(3)(3)(3)
y = 2(27)
y = 54
<span>6.)y=x/2+9;x=-12
y = (-12)/2 + 9
y = -6 + 9
y = -3</span>
well what i got was:
the exact form: 233/28
decimal form: 7.96428571...
mixed number form: 7 27/28
not sure if this is right at all but i hope it helps at least a little
Answer:
According to the graph about <u>5 percent</u> of households in Africa owns a computer in 2008.
2013 about 1/3 of all households in <u>Asia</u> had a computer.
The number of households with a computer is <u>increasing</u> in all regions overtime.
