Answer:

240

Step-by-step explanation:

Miss Jennifer is buying pencils in packs of 12, notebooks in packs of 16, and red pens in boxes of 20. She needs to have the same number of pencils, notebooks, and red pens. What is the least number of packs of each type should she buy?

So you know 12, 16, and 20 are even so you would find the LCM (Least Common Multiple) so 12 is 12, 24, 36, 48, 60, 72, 84, 96, 108, 120 so I know 20 and 12 go in 120 because 20, 40, 60, 80, 100, 120 but I know 16 is not but 12, 16, 20 is able to got toe 240 because 16 is able to and I know double of 120 is 240 and since 20 and 12 can go to 120 my answer is 240.

A farmer has 1800 m of fencing. He needs to create

NeTakaya

Answer:

67,500 m²

Step-by-step explanation:

ASSUMING the fields look like this __________________

| | |

| | | W

|_________|_________|

Let L be the length of the combined field and W be the width

2L + 3W = 1800

2L = 1800 - 3W

L = 900 - 1.5W

A = LW

A = (900 - 1.5W)W

A = 900W - 1.5W²

Area will be maximized when the derivative equals zero.

dA/dW = 900 - 3W

0 = 900 - 3W

3W = 900

W = 300 m

L = 900 - 1.5(300)

L = 450 m

A = LW = 450(300) = 135,000 m²

so each sub field is 135000/2 = 67,500 m²

15. Gwen had a painting that had a length of 5 feet and a width of 3.5 feet.

victus00 [196]

Answer:

D. 15 by 10.5

Step-by-step explanation:

If the original painting has dimensions of 5 by 3.5, and has a scale factor of 1, then if we are trying to find the dimensions of the same thing but with a scale factor of 3, then we need to multiply the dimensions by 3.

5*3 = 15

3.5*3 = 10.5

The new dimensions are 15 by 10.5.

Hope this helps. Have a nice day.
