So this box will probably be very flat. Draw it out. There would be 4 surfaces with the surface area of 0.25*38. Which equals 9.5. Multiply that by 4 and it's 38. Now take the bigger surfaces. They will be 38 squared, which is 1444. Multiply that by 2, because there are 2 of those surfaces, and you get 2888. To get the total you add them up: 38+2888=2926. So the answer is 2926 meters squared.
P.S: I copied this answer from the answer I gave to someone else, because they asked the same question.
Answer:
(-2, 6)
Step-by-step explanation:
you can use the substitution method:
(4, 7) Is 7 > 8 - 1? No, 7 is not greater than 7
(1, -4) Is -4 > 2 - 1? No, -4 is not greater than -1
(-2, 6) Is 6 > -4 - 1? Yes, 6 is greater than -5
(0, -8) Is -8 > -1? No
Formula of volume of a cylinder = πr²h
V = πr²(2)
32π= 2πr²
r² = 16 Divide by 2π
r = 4 Square root both sides
<em>The radius is 4) 4</em>
Answer:
Amount of sodium in a hot dog = 860 mg.
Amount of sodium in a cup of cottage cheese = 1000 mg.
Step-by-step explanation:
Let the amount of sodium in a hot dog be x mg and the amount in a cup of cottage cheese be y mg.
2x + 3y = 4720
5x + 2y = 6300
Multiply the first equation by 2 and the second by 3. We get:
4x + 6y = 9440 (a)
15x + 6y = 18900 (b)
Subtract: (b) - (a):
11x = 9460
x = 9460 / 11 = 860 mg.
To find we we substitute x = 860 in the first original equation:
2(860) + 3y = 4720
3y = 3000
y = 1000 mg.
Answer:
30=3x
so divide 30 by 3 and you'll get x
