Answer:

length = 11 yard

width =  5 yard

Step-by-step explanation:

Area of a rectangle = L W

where A = 55 yard

           L = 3W - 4

find: Length

        width

solution:

A = L W

55 = (3W - 4) W

55 = 3W² - 4W

3W² - 4W - 55 = 0

use quadratic equation to solve for W:

W = - (-4) ± √(-4)² - 4(3)-55

                    2(3)

W = 5,  W = -11/3

substitute W=5 to equation L = 3W - 4 to solve for L

L = 3W - 4

L = 3(5) - 4

L = 15 - 4

L = 11

therefore, the dimensions of a rectangle:

length = 11 yard

width =  5 yard

Answer:

Step-by-step explanation:

This is because when calculating the slope of given points, we must use this simple formula:

(simplified version)

The actual formula is

1. Find the difference of the x axis'

ANSWER: The difference of the x axis should be 11-(-5)= 16

2. Find the difference of the y axis'

ANSWER: The difference of the y axis should be 2-(6)= -4

3.  Substitute these new values into the formula Δy/Δx

ANSWER: You should get -4/16 which is -0.25

4. Your answer will be -0.25

Answer:

33.34%.

Step-by-step explanation:

Given that,

The actual price of the shirt = $36

Price on sale = $24

We need to find the percent of the decrease. The formula for the percentage is given by :

[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]

Putting all the values,

[tex]\%=\dfrac{24-36}{36}\times 100\\\\=33.34\%[/tex]

So, the percentage decrease in the price of the shirt is 33.34%.

Answer:

5(3x+4)=23

5*3=15 5*4=20

15x+20=23

      -20=-20

15x=3

divide by 15 from both sides

x=0.2

Step-by-step explanation:

Answer:

5(3x+4)=23

5*3=15 5*4=20

15x+20=23

     -20=-20

15x=3

divide by 15 from both sides

x=0.2

Explanation: In a fraction, the number of equal parts being described is the numerator (from Latin: numerātor, "counter" or "numberer"), and the type or variety of the parts is the denominator (from Latin: dēnōminātor, "thing that names or designates"). As an example, the fraction 8/5

amounts to eight parts, each of which is of the type named "fifth". In terms of division, the numerator corresponds to the dividend, and the denominator corresponds to the divisor.

Informally, the numerator and denominator may be distinguished by placement alone, but in formal contexts they are usually separated by a fraction bar. The fraction bar may be horizontal (as in 1/3), oblique (as in 2/5), or diagonal (as in 4⁄9). These marks are respectively known as the horizontal bar; the virgule, slash (US), or stroke (UK); and the fraction bar, solidus, or fraction slash. In typography, fractions stacked vertically are also known as "en" or "nut fractions", and diagonal ones as "em" or "mutton fractions", based on whether a fraction with a single-digit numerator and denominator occupies the proportion of a narrow en square, or a wider em square. In traditional typefounding, a piece of type bearing a complete fraction (e.g. 1/2) was known as a "case fraction", while those representing only part of fraction were called "piece fractions".

Answer:

$537.60

Step-by-step explanation:

Xochitl has saved $201.60.

Yamka has saved 2/3 the amount Xochitl saved.

The amount Yamka has saved us calculated as:

2/3 × $201.60

= $134.40

Zack has saved 1.5 times the amount Yamka saved.

The amount Zack has saved is

1.5 × $134.40

= $201.60

How much have they saved all together?

This is calculated as:

$201.60 + $134.40 + $201.60

= $537.60

Step-by-step explanation:

17 /21=.809

The function is odd, since

f(-x) = (-x)³ + (-x)

… = (-1)³ x³ - x

… = -x³ - x

… = -(x³ + x)

… = - f(x)

so the answer is B.

Answer:

width = 1.77845 ft

length = 7.1138 ft

height = 5.691 ft

total cost = $759.09

Step-by-step explanation:

volume = length x width x height

length = 4 width

base of the rectangle = 4 x 1 w = 4w²

72 (volume) = 4w²h

18 = w²h

f(c) = (2 x 4w² x $10) + (2 x wh x $5) + (2 x 4wh x $5)

f(c) = 80w² + 10wh + 40wh

f(c) = 80w² + 50wh

since we need only 1 variable (width), we have to substitute h:

h = 18/w²

f(c) = 80w² + 50w(18/w²) = 80w² + 900/w

f'(c) = 160w + 900/w²

0 = (160w³ + 900)/w²

0 = 160w³ + 900

0 = 20(8w³ + 45)

0 = 8w³ + 45

8w³ = -45

w³ = -45/8

w = ∛-45/8 = -1.77845 and 1.77845

since w cannot be negative, then it must be 1.77845

-8 + 7 = -1

so the answer would be:

-xy or -1xy

Answer:

-xy

Step-by-step explanation:

Add -8xy and 7xy= -xy

Answer:

x = 30°

Step-by-step explanation:

Since m and n are perpendicular, then

y + 70° = 90° ( subtract 70° from both sides )

y = 20°

thus 40 + y = 40° + 20° = 60°

Then

x + 60° = 90° ( subtract 60° from both sides )

x = 30°

Answer:

Ms. Cohen can buy 12 poxes of crayons.

Step-by-step explanation:

Ms. Cohen can buy 12 boxes of crayons with the rest of her money. In the question it states she only wants to buy 1 poster not more than one so if she buys 1 poster that's

30-5-25

and than you can just count up by 2 till you get the closest to 25

25-24=1$

24/2 = 12

Hope this helps.

The number of boxes of crayons that can be bought is needed.

The number of boxes that can be bought at most is 12.

Let [tex]x[/tex] be the number of boxes of crayons

Total amount of money = $30

Cost of one box = $2

Cost of poster = $5

The linear inequality will be

[tex]2x+5\leq 30\\\Rightarrow x\leq\dfrac{30-5}{2}\\\Rightarrow x\leq 12.5[/tex]
