Answer:

  2 liters

Step-by-step explanation:

The applicable proportion can be written ...

   amount/percentage = 1260 mL/63% = x/100%

  2000 mL = x = 2 liters

The full carton held 2 liters of milk.

Here's the solution :

perimeter of equilateral triangle = 3 × x = 3x

perimeter of square = 4 × (x + 10)

now, according to above statement :

permission (square) = 3 × perimeter (triangle)

that is :

therefore, side of triangle = 8 cm

Answer:

Let the side of the equilateral triangle = x

so the side of the square =  x+10

The perimeter of the triangle = 3x

and the perimeter of the square = 4(x+10)

condition : the perimeter of the square is 3 times the perimeter of the triangle.

so, 4(x+10) =  3*(3x)

f ' (0) exists if the limit,

[tex]\displaystyle \lim_{h\to0}\frac{f(0+h)-f(0)}h[/tex]

exists, and f ' (0) has the value of this limit.

In order for this limit to exist, both limits from either side of h = 0 must exist.

Suppose h < 0. Then 0 + h is also negative, so by definition of f(x) we have

f (0 + h) = ((0 + h) + 1)² = h ² + 2h + 1

Then in the limit, if h is approaching 0, it must be from below or from the left:

[tex]\displaystyle \lim_{h\to0^-}\frac{f(0+h)-f(0)}{h} = \lim_{h\to0^-}\frac{(h^2+2h+1)-1}{h} = \lim_{h\to0^-}(h+2) = 2[/tex]

Now suppose h > 0, so that 0 + h is positive and h approaches 0 from above or from the right. Then

f (0 + h) = 2 (0 + h) + 1 = 2h + 1

and

[tex]\displaystyle \lim_{h\to0^+}\frac{f(0+h)-f(0)}h = \lim_{h\to0^+}\frac{(2h+1)-1}{h} = \lim_{h\to0^+}2 = 2[/tex]

Both one-sided limits match, so f ' (0) = 2.

Answer:

$7.10

Step-by-step explanation:

1 bar = $1.29

10 bars = 10 x $1.29 = $12.90

Change received = $20 - $12.90 = $7.10

Answer:

7.1

Step-by-step explanation:

1 twix bar = $1.29

10 twix bar = $12.9

change = 20 - 12.9

= $7.1

The question is an illustration of inequalities.

The inequality that represents Lashonda's amount of exercise is: [tex]\mathbf{t \ge 50}[/tex]

The given parameter is:

[tex]\mathbf{Minutes = At\ least\ 50}[/tex]

In inequality, at least means greater than or equal to.

So, the above equation becomes:

[tex]\mathbf{Minutes \ge 50}[/tex]

From the question, we understand that the number of minutes should be represented with t.

So, we have:

[tex]\mathbf{t \ge 50}[/tex]

Hence, the inequality is: [tex]\mathbf{t \ge 50}[/tex]

Answer:

D) 35 sq ft

Step-by-step explanation:

The options are:

A) 24 sq ft      B) 70 sq ft      C) 12 sq ft      D) 35 sq ft

So, when calculating the area of a regular rectangle or square, you need to multiply the base by the height (area=base*height)

So it is as simple as 7 multiplied by 5 which is 35 (7*5=35), so the answer is D) 35 square feet.

Answer:

you would use 3/4 of a gallon per room, so you would multiply 3/4 x 4., which equals 3 gallons

Step-by-step explanation:

Given [tex]\frac{x*x^{-2} }{x^{13}}[/tex]

= [tex]\frac{x*x^{-2} }{x^{13}} = \frac{x^{-1} }{x^{13}}[/tex]

According to the Negative Exponent Rule, [tex]a^{-n} = \frac{1}{a^{n}}[/tex]

Therefore, [tex]\frac{x^{-1} }{x^{13}} = \frac{1}{x^{1}*x^{13}} = \frac{1}{x^{13+1}}= \frac{1}{x^{14}}[/tex]

In other words,  [tex]x^{-1}[/tex] became positive because of the Negative Exponent Rule. Once you bring [tex]x^{-1}[/tex] down towards the denominator, you're essentially removing its negativity and turning its exponent into a positive value. Once that takes place, then you could apply the Product Rule of Exponents onto the exponents in the denominator, where it states, [tex]a^{m}a^{n} = a^{m+n}[/tex].
