A bottle fruit juice holds 1.89L. If shakira bought almost 6L of fruit juice, how many bottles did she buy

anyanavicka [17]

Since the question is asking how many bottles Shakira bought that was ALMOST 6L, she bought about 3 bottles.

6.00 / 1.89= 3.17460317= 3.175
Liters/ Bottle of Juice Amount

To check your work, multiply 3.175 by 1.89, you’d get 6.00075, about 6L.

The question is asking ALMOST, so it can’t be exact, so uyour answer would instead be 3.
3• 1.89=5.67L

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric

Murrr4er [49]

Answer:

$A = 781250\,m^{2}$ , $x = 625\,m$ , $y = 1250\,m$

Step-by-step explanation:

The perimeter covered by the electric fence in meters is:

$2\cdot x + y = 2500$

The area of the rectangle is:

$A = x\cdot y$

$A = x \cdot (2500-2\cdot x)$

Let differentiate the previous equation and equates to zero:

$2500-4\cdot x = 0$

The critical point is:

$x = 625\,m$

By the Second Derivative Text, it is proved that critical point lead to a maximum:

$\frac{d^{2}A}{dx^{2}} = -4$

The other side of the rectangle is:

$y = 1250\,m$

The largest area than can be enclosed is:

$A = (625\,m)\cdot (1250\,m)$

$A = 781250\,m^{2}$

The dimensions of the triangle are:

$x = 625\,m$

$y = 1250\,m$

There were 30 cookies in a jar. Eileen divided the cookies into 12 equal shares. How many cookies were there in each share?

Sedbober [7]

The answer is 2.5 cookies also known as 2 and 1/2 Because 12 can go into 30, twice , which gives us 24 and 30-24= 6 so we put a decimal point to the right of 2 and we put a 0 and bring the zero down to make 60. 12 goes into 60, 5 times so the answer is 2 1/2 or 2.5
