Answer:

The answer to your question is: y = 8x

Step-by-step explanation:

As both lines are parallels, then the slope is the same.

From the line given, get the slope

m = 8

Point (0, 0)

(y - y1) = m(x - x1)

(y - 0) = 8(x - 0)

y = 8x

Jocelyn Angelica bought a dress marked, "Sale Price is 18% Off." The cashier told her she saved $23. How much was the price of t

agasfer [191]

Answer:

$28.05

Step-by-step explanation:

Since the sale price is 18% off, this means we pay 100-18 = 82% of the original price. 82% = 82/100 = 0.82; using x as the original price, we can set up the equation

0.82x = 23

Divide both sides by 0.82:

0.82x/0.82 = 23/0.82

x = 28.05

A farmer wishes to enclose a rectangular pasture with 1200 ft of fence. He needs to divide this rectangle into two smaller recta

Minchanka [31]

Answer: $60,000 ft^2$

Step-by-step explanation:

Given

total of 1200 ft of fence is available

Suppose rectangular pasture has following dimension as shown in figure.

total perimeter

$P=4a+3b$

$1200=4a+3b$

$4a=1200-3b$

$a=300-\frac{3}{4}b$

Area of rectangle is

$A=2a\times b$

$A=2(300-\frac{3}{4}b)b$

$A=2[300 b-\frac{3}{4}b^2]$

For maximum area, differentiate A w.r.t b

$\frac{\mathrm{d} A}{\mathrm{d} b}=300-\frac{3}{2}b=0$

$300=\frac{3}{2}b$

$b=200 ft$

so $a=300-150=150\ ft$

so area is

$A=2\times 150\times 200$

$A=60,000 ft^2$
