If you have 36 ft of fencing, what are the bases and side lengths of the different parallelograms you could enclose with the fen

serious [3.7K]

Answer:

$(l,w) = (1,17)$

$(l,w) = (2,16)$

$(l,w) = (3,15)$

---

$(l,w) = (9,9)$

Step-by-step explanation:

Given

$P = 36ft$ --- perimeter

$l \to length$

$w \to width$

Required

Possible dimension of different parallelogram

The perimeter is calculated as:

$P=2(l+w)\\\\\\$

So,we have:

$2(l+w)=36$

Divide by 2

$l + w = 18$

Since l and w must be positive integers, the possible dimensions are:

$(l,w) = (1,17)$

$(l,w) = (2,16)$

$(l,w) = (3,15)$

---

$(l,w) = (9,9)$

One kind of hard candy sells for $.89 per kilogram another sells for $1.10 per kilogram how many kilograms of each kind a need t

Furkat [3]

Answer:

20kg of $0.89 candy

10kg of $1.10 candy

Step-by-step explanation:

Candy 1 = 0.89 per kg

Candy 2 = 1.10 per kg

Total kilogram, kg = 30

Let candy 1 = x ; candy 2 = (30 - x) ;

0.89x + 1.10(30 - x) = 0.96(30)

0.89x + 33 - 1.10x = 28.8

0.89x - 1.10x = 28.8 - 33

-0.21x = - 4.2

x = 4.2 / 0.21

x = 20

20kg of $0.89 candy

(30 - x) = (30 - 20) = 10kg

10kg of $1.10 candy

An office supply store recently sold a black printer ink cartridge for $17.99 and a color printer ink cartridge for $20.99. At t

UNO [17]

Answer:

40 black ink cartridges and 19 colored ink cartridges

Step-by-step explanation:

Let $b$ represent the number of black printer ink cartridges sold. Let $c$ represent the number of color printer ink cartridges sold.

Set up a system of equations:

$\displaystyle\\\begin{cases}b+c=59\\17.99b+20.99c=1,118.41\end{cases}$

$b+c=59\implies b=59-c$

Substitute:

$\displaystyle\\17.99(59-c)+20.99c=1,118.41\\\implies c=\boxed{19}$

$\implies b+19=59\implies b=\boxed{40}$

⇒ 40 black ink cartridges, 19 colored ink cartridges (ans)
