On average,ea rectangular garden ha an area of 144 meter square. During a redesign of the garden center, the dimension of the re
aksik [14]

Answer:

New dimensions are; Width = 12m and Length = 12m

Step-by-step explanation:

Let length of rectangle be L

Let width be W

Area of rectangle has a formula;

Area = Length x Width = LW

We are given the area = 144 m²

So,

LW = 144 - - - (eq1)

Now, we are told that width is doubled and length is decreased by 12m but area remains the same.

Thus, we have;

Width as 2W and Length as L - 12.

Area = 2W(L - 12)

So,

2W(L - 12) = 144 - - - (eq2)

Equating eq 1 and 2,we have;

LW = 2W(L - 12)

W will cancel out to give;

L = 2(L - 12)

L = 2L - 24

2L - L = 24

L = 24m

From equation 1, LW = 144

Thus; W = 144/L = 144/24

W = 6m

So new design of rectangle now has a dimension of;

Width = 2W = 2 × 6 = 12m

Length = L - 12 = 24 - 12 = 12m

So, new dimensions are; Width = 12m and Length = 12m

A pet store has 6 cats 6,5,9,11,11,10 find the mean weight of these cats
aliina [53]

Answer:

8.7

Step-by-step explanation:

To find the mean first you have to add up all the weight of the cats which is:6+5+9+11+11+10= 52

After, you have to divide the total weight by the number of cats there are

which is: 52/ 6=8.66666666667

Since, this is a really long number you would normally round the number to the nearest tenth which is 8.7
