Answer:

length 21yd

width 15yd

Step-by-step explanation:

Actually it does factor

x(x+6)=315

x²+6x=315

x² +6x - 315 = 0

(x+21)(x-15) = 0

x= -21. discard as can’t have a negative distance

x=15

So dimensions are 15 and 21

Answer:

c. y + 1 = -⅕(x - 2)

Step-by-step explanation:

To write the equation in point-slope form, we need to know the slope (m) and coordinates of a point the line passes through.

The equation would be in the form of y - b = m(x - a).

(a, b) = (2, -1)

Since the line is perpendicular to y = 5x + 3, the slope will be the negative reciprocal of 5 which is -⅕

m = -⅕.

Substitute a = 2, b = -1, and m = -⅕ into y - b = m(x - a).

Thus:

y - (-1) = -⅕(x - 2)

y + 1 = -⅕(x - 2)

Answer:

n = 19.

Step-by-step explanation:

If there are x guinea pigs then there are 3/2 x and 2/3 x rats.

So n = x + 3/2 x + 2/3 x

n = 19x / 6

19x = 6n

Let x = 6 , then n = 19*6 / 6 = 19.

Now n and x must be whole numbers so x is 6 and n = 19 are the smallest possible values.

w=15

Step-by-step explanation:

The way I found the answer is dividing 120 by 8 which equaled 15 and I made sure it was correct as I multiplied 8 by 15 and the answer was 120.

Answer:

7.5 OR 8 (Depending on whether you are rounding or not)

Step-by-step explanation:

30 x 4 = 120 oz

120 oz to pounds is 7.5 but if you are rounding then its 8.

Answer:

Thanksgiving, median = 17

New year's eve, median = 8

Thanksgiving, IQR = 12

New year's eve, IQR = 10

THANKSGIVING has greater variability

Step-by-step explanation:

The median value of a box plot is the line which lies in the middle of the box :

From the plot, the best estimate :

Thanksgiving, median = 17

New year's eve, median = 8

THE Interquartile range, IQR is the difference between the upper quartile and lower quartile values, Q3 - Q1 ;

Lower quartile = the starting point of the box

Upper quartile = the endpoint of the box

From the plot ; Best estimate :

Thanksgiving :

Q1 = 12 ; Q3 = 24

IQR = Q3 - Q1 = 24 - 12 = 12

New year's eve :

Q1 = 5 ; Q3 = 15

IQR = Q3 - Q1 = 15 - 5 = 10

Thanksgiving :

Range = Maximum - Minimum

Range = (29 - 5) = 24

New year's eve:

Range = Maximum - Minimum

Range = 22 - 3 = 19

Hence, Thanksgiving has greater variability

Answer:

Move all terms containing x to the left side of the equation.

−5x+5=25

Move all terms not containing x to the right side of the equation.

−5x=20

Divide each term by −5 and simplify.

x=−4

Step-by-step explanation:

Answer:

[tex]15x + 5 = -10x + 25[/tex]

[tex]15x+5-5=-10x+25-5[/tex]

[tex]15x=-10x+20[/tex]

[tex]15x+10x=-10x+20+10x[/tex]

Answer:

81 degrees

Step-by-step explanation:

Applying the inscribed angle theorem, the measure of ∠EAB is: 81°.

The inscribed angle theorem states that an intercepted arc measure is always twice the measure of the inscribed angle in a circle.

Given the following:

We would therefore have the following:

1/2(ADB) = m∠EAB

Substitute

1/2(162) = m∠EAB

m∠EAB = 81°

Therefore, applying the inscribed angle theorem, the measure of ∠EAB is: 81°.

Answer:

nose de ecuaciones sorry :c

Step-by-step explanation:

An exponential equation is characterized by an initial value "a" and a rate "b". Because Jerald is investigating a depreciation, the rate "b" will be less than 1.

The exponential equation is [tex]y = 12500(0.86)^x[/tex] and the depreciated amount in 2010 is approximately 2379

I've added the missing data as an attachment.

An exponential equation is represented as:

[tex]y = ab^x[/tex]

Where:

[tex]a \to[/tex] the first term

[tex]b \to[/tex] rate

[tex]x \to[/tex] years after 1999

[tex]y \to[/tex] depreciated value

When [tex]x = 0\ \&\ y=12500[/tex]

The equation [tex]y = ab^x[/tex] is:

[tex]12500 = ab^0[/tex]

[tex]12500 = a*1[/tex]

[tex]12500 = a[/tex]

[tex]a =12500[/tex]

When [tex]x = 1\, \&\ y = 10750[/tex]

The equation [tex]y = ab^x[/tex] is:

[tex]10750 = ab^1[/tex]

[tex]10750 = ab[/tex]

Substitute [tex]a =12500[/tex]

[tex]10750 = 12500 \times b[/tex]

Solve for b

[tex]b =\frac{10750 }{12500}[/tex]

[tex]b =0.86[/tex]

So, the equation is:

[tex]y = ab^x[/tex]

[tex]y = 12500(0.86)^x[/tex]

To calculate the depreciated value in 2010, we first solve for x in 2010

[tex]x = 2010 - 1999[/tex]

[tex]x = 11[/tex]

So, the depreciated value (y) is:

[tex]y = 12500(0.86)^x[/tex]

[tex]y = 12500 \times 0.86^{11}[/tex]

[tex]y = 2379[/tex]

Answer:

$90

Step-by-step explanation:

The shoes now cost 130% of the original cost

The original cost is 100%

Take the new amount and divide it by 130:

117/130 = .90

Then multiply that number by 100 to get the original percent

.90 x 100 = $90

To check, multiply $90 by 130% or 1.30 to make sure that a 30% increase makes the product $117

$90 x 1.30 = $117

(a) The amount financed is $22,000.

(b) Total amount of monthly payments is $31,500.

(c) Amount of the finance charge is $9,500.

Down payment is the amount which has to be paid at the beginning of a transaction while buying a house or a car.

Given that,

Purchase price of the car = $27,000.00

Down payment = $5,000.00

Number of monthly payments = 60

Amount of monthly payment = $525

(a) Amount financed = Purchase price - Down payment

                                  = $27,000.00 - $5,000.00

                                  = $22,000

(b) Total amount of monthly payments = 60 × $525

                                                                = $31,500

(c) Amount of the finance charge = $31,500 - $22,000

                                                       = $9,500

Hence the amount financed is $22,000.
