Antonius the chef wants to cook several batches of lasagna and spaghetti for his restaurant. He plans to use at least 4.54.5 kil
yaroslaw [1]

Answer: No he does not meet both of his expectation by cooking 10 batches of spaghetti and 4 batches of lasagna.

Step-by-step explanation:

Since here S represents the number of batches of spaghetti and L represents the total number of lasagna.

And,  the chef planed to use at least 4.5 kilograms of pasta and more than 6.3 liters of sauce to cook spaghetti and lasagna.

Which is shown by the below inequality,

0.3S+0.65L \geq 4.5 ----------(1)

And,  0.25S+0.8L >6.3 --------(2)

By putting S = 10 and L = 4 in the  inequality (1),

0.3\times 10+0.65\times 4 \geq 4.5

⇒ 5.6\geq 4.5(true)

Thus, for the values  S = 10 and L = 4 the inequality (1) is followed.

Again By putting S = 10 and L = 4 in the  inequality (2),

0.25\times 10+0.8\times 4 >6.3

⇒ 5.7>6.3( false)

But, for the values  S = 10 and L = 4 the inequality (2) is not  followed.

Therefore, Antonius does not meet both of his expectations by cooking 10 batches of spaghetti and 4 batches of lasagna.

Given: 18x-2(3x+1)=5x-16<br> Prove: x=-2
zlopas [31]

Answer:

True

Step-by-step explanation:

Evaluate 18 x - 2 (3 x + 1) = 5 x - 16 where x = -2:

-2×18 - 2 (1 - 2×3) = -2×5 - 16

3 (-2) = -6:

-2×18 - 2 (-6 + 1) = -2×5 - 16

1 - 6 = -5:

-2×18 - 2-5 = -2×5 - 16

18 (-2) = -36:

-36 - 2 (-5) = -2×5 - 16

-2 (-5) = 10:

10 - 36 = -2×5 - 16

5 (-2) = -10:

10 - 36 = -10 - 16

10 - 36 = -26:

-26 = -10 - 16

-10 - 16 = -26:

-26 = -26

-26 is equal to -26:

Answer:  True

If a rectangle has an area of 36 square units, what could the dimensions be?
Oxana [17]

The area of a rectangle is length times width. Since a square's length is equal to its width, a square's area is equal to the length of one side times itself. So, reversed, the square root of the square's area gives the length of one side. In this case, the square root of 36 square centimeters is 6 centimeters. Again, since all four sides of a square are the same, its perimeter is equal to the length of one side times four. For a square with one side equal to 6 centimeters, the perimeter equals 24 centimeters.
