Answer:

You can always compare to cost together but the big thing to look for is that you could be spending less for more on a product or the other way around, spending more for less product. you always want to go with the product that you are spending less money to get more product out of it.

Step-by-step explanation:

for example, say you are buying a pack of pencils, there is a pack of

10 pencils for 5 dollars

and

50 pencils for 10 dollarsthan

you would want to buy the second pack of pencils because you are getting each pencil for 50 cents rather than 2 dollars for each pencil in the first pack.

You have 100 feet of fencing and decide to make a rectangular garden. What is the largest area enclosed

k0ka [10]

Answer:

625 ft^2

Step-by-step explanation:

Given

$P = 100$ --- perimeter

Required

The largest area

The perimeter is calculated as:

$P = 2 * ( L + W)$

So, we have:

$2 * ( L + W) = 100$

Divide both sides by 2

$L + W = 50$

Make L the subject

$L = 50 - W$

The area is calculated as:

$A= L * W$

Substitute $L = 50 - W$

$A= (50 - W) * W$

Open bracket

$A = 50W - W^2$

Differentiate with respect to W

$A' = 50 -2W$

Set to 0; to get the maximum value of W

$50 - 2W = 0$

Collect like terms

$-2W = -50$

Divide by -2

$W = 25$

So, the maximum area is:

$A = 50W - W^2$

$A = 50 * 25 - 25^2$

$A = 1250 - 625$

$A = 625$

Find the area of the rhombus in m squared

Nataly [62]

Answer:

$\boxed{\bold{100 \ m^2}}$

Step By Step Explanation:

Area Of Rhombus: $\bold{\frac{pq}{2} }$

Identify 'p'

5 + 5 = 10

p = 10

Identify 'q'

10 + 10 = 20

q = 20

$\bold{10 \ \cdot\ \ 20 \ = \ 200}$

$\bold{200 \ \div \ 2 \ = \ 100}$

➤ $\boxed{\bold{Mordancy}}$

How many trucks carried only late variety?

murzikaleks [220]

9514 1404 393

Answer:

late only: 15
extra-late only: 24
one type: 43
total trucks: 105

Step-by-step explanation:

It works well when making a Venn diagram to start in the middle (6 carried all three), then work out.

For example, if 10 carried early and extra-late, then only 10-6 = 4 of those trucks carried just early and extra-late.

Similarly, if 30 carried early and late, and 4 more carried only early and extra-late, then 38-30-4 = 4 carried only early. In the attached, the "only" numbers for a single type are circled, to differentiate them from the "total" numbers for that type.

a) 15 trucks carried only late

b) 24 trucks carried only extra late

c) 4+15+24 = 43 trucks carried only one type

d) 38+67+56 -30-28-10 +6 +6 = 105 trucks in all went out
