An 18-pound bag of dog food is $27. What is the constant of proportionality that relates cost in dollars, y, to the number of pounds of dog food, x ?

30% is the answer........

Answer:

Option C 30%

Step-by-step explanation:

let x%of 50 is 15

X/100×50=15

50x/100=15

X/2=15

X=30

So option C. (30%) is correct

Answer:

Step-by-step explanation:

Step one:

given

original price= $60

discount =20% of 60

discount = 20/100*60

discount = 0.2*60

discount = $12

selling price= 60-12= $48

Added price= 10% off $48

Added price= 10/100 *48

Added price= 0.1 *48

Added price= $4.8

new price= 4.8-48=$43.2

the new price of the jacket is $43.2

1. The jacket is now 40% off its original price

40/100*60=$24-----False

2. The jacket now costs $48.00-----False

3.  The jacket is now 72% of its original price= 72/100*60=$43.2----True

4. The jacket now costs $43.20------True

Answer:

Total area of board = 36x² + 324 + 216x

Step-by-step explanation:

Given:

Side of square = x + 3

Total number of square = 6 x 6 = 36

Area of each square = Side x Side

Area of each square = (x + 3)²

Area of each square = x² + 9 + 6x

Total area of board = 36[Area of each square]

Total area of board = 36[x² + 9 + 6x]

Total area of board = 36x² + 324 + 216x

Answer: y = 6x-4

Step-by-step explanation:

The formula for slope-intercept is y=mx+b so all you have to do is plug in the slope which is m and plug in the y intercept which would be b

Answer:

The Pythagorean theorem is widely used in everyday life. one of them in the carpentry sector. the craftsman ensures that the corners of the building foundation really right angled by using a triangle with a combination of side sizes 60 cm, 80 cm, and 100 cm.

Step-by-step explanation:

How to do the Pythagorean Theorem

KNOW: the height of the triangle is 5 cm and the slope of the triangle is 13

searching for: base of triangle , X

Answer:

X² = a² - b²

X² = 13² - 5²

X² = 169 - 25

X = 144

X. =√144

X =12

that's how to find the result of the Pythagorean Theorem

73%  of the model is shaded,  146/200 is the equivalent ratio.0.73 is the equivalent decimal and 146/200 is the equivalent fraction

A fraction represents a part of a whole.

Given,

A grid model with 100 squares. 73 squares are shaded.

We need to find percent of the model is shaded

As there are 100 grids with 73 shaded.

73%  of the model is shaded

Now let us find equivalent ratio of 73/100

Multiply numerator and denominator 2

73/100×2/2

146/200

146/200 is the equivalent ratio.

73/100=0.73 is the equivalent decimal.

146/200 is the equivalent fraction.

Hence,73%  of the model is shaded,  146/200 is the equivalent ratio.0.73 is the equivalent decimal and 146/200 is the equivalent fraction.

Answer:

b)15.75 and 2.9432

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

The mean of a binomial distribution is:

[tex]\mu[/tex] = np

And the standard deviation is

[tex]\sigma[/tex] =  √(npq)

where,

n = 35,

p = 0.45,

and q = 1 - 045 =  0.55

Now mean is

= 35 × 0.45

= 15.75

And, the standard deviation is  

= √(35 × 0.45 × 0.55)

= 2.9432

Hence, the correct option is B.

Answer:

x = 36.27

Step-by-step explanation:

By using the steps to find sin θ backwards, we can find x, the hypotenuse.

sin θ = [tex]\frac{opposite}{hypotenuse}[/tex] or side [tex]\frac{a}{c}[/tex] (as seen in my example picture).

We already know the value for sin (α), which is 32° because its given. The opposite side (a) is 20 and the hypotenuse side (c) is x which are both also given.

So the equation now looks like:

sin 32° = [tex]\frac{20}{x}[/tex]

Don't solve for the sin 32 yet! First, we have to isolate the variable.

To get rid of the x in the denominator you have to multiply both sides by x:

( sin 32 ) · x = ( [tex]\frac{20}{x}[/tex] ) · x

( sin 32 ) x = 20

Then, you have to divide both sides by sin 32 to get x by itself:

(( sin 32 ) x ) ÷ ( sin 32 ) = 20 ÷ ( sin 32 )

x = 20 ÷ ( sin 32 )

Lastly, you have to use a calculator to find 20 ÷ ( sin 32 ), and it should give you 36.2695543766.

The question asks you to round to 2 decimal places so:

x = 36.27

Answer:

x = ± 6i

Step-by-step explanation:

Given

x² + 27 = - 9 ( subtract 27 from both sides )

x² = - 36 ( negative value indicates the solutions are complex )

Take the square root of both sides

x = ± [tex]\sqrt{-36}[/tex] = ± 6i
