Answer:

18.00$

Step-by-step explanation:

Answer:

$18.00

Step-by-step explanation:

Thus, a product that normally costs $20 with a 10 percent discount will cost you $18.00, and you saved $2.00.  You can also calculate how much you save by simply moving the period in 10.00 percent two spaces to the left, and then multiply the result by $20 as follows: $20 x .10 = $2.00 savings.  Furthermore, you can get the final price by simply deducting .10 from 1 and multiplying it by $20 as follows: (1 - .10) x $20 = $18.00 final price.

x = 0,-1,-2,1,2

y = -3,-5,-7,-1,1

(0,-3)

(-1,-5)

(-2,-7)

(1,-1)

(2,1)

Step-by-step explanation:

y = 2x - 3

x = 0,-1,-2,1,2

y = ?,?,?,?,?

x = 0

y = 2x - 3

y = 2(0) - 3

y = 0 - 3

y = -3

x = -1

y = 2x - 3

y = 2(-1) - 3

y = -2 - 3

y = -5

x = -2

y = 2x - 3

y = 2(-2) - 3

y = -4 - 3

y = -7

x = 1

y = 2x - 3

y = 2(1) - 3

y = 2 - 3

y = -1

x = 2

y = 2x - 3

y = 2(2) - 3

y = 4 - 3

y = 1

Check:

x = 0,-1,-2,1,2

y = -3,-5,-7,-1,1

(0,-3)

(-1,-5)

Step-by-step explanation:

Size of Interior angle = 180° - 360°/n, where n is the number of sides of the regular polygon.

We have 180° - 360°/n = 160°.

=> 360°/n = 20°, n = 18.

Therefore it is a 18-sided regular polygon.

Answer:

[tex]\huge\boxed{m\angle P = 94\textdegree}[/tex]

Step-by-step explanation:

In order to answer this question, we need to note a couple of things about the angle relationships in a pentagon.

Since we know the sum of all of the angles will be 540, we can create an addition statement to find out the value of x.

[tex]132 + (4x-10) + (5x-11) + 128 + (4x+2)=540[/tex]

Let's solve for x.

Now that we know the value of x, we can substitute it into the expression for point P ([tex]4x+2[/tex]) to find it's value.

Therefore, the angle of measure P is 94°.

The dog has been dieting for 19 weeks.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

According to the given problem,

Starting weight of the dog = 89.5 pounds

Halfway weight of the dog = 80 pounds

Weight the dog loses per week = 0.5 pounds

Weight loss = (89.5 - 80) pounds

                    = 9.5 pounds

If the dog loses 0.5 pounds in 1 week,

Then the dog will lose 9.5 pounds in (9.5 × 2) weeks

⇒ The dog will lose 9.5 pounds in 19 weeks.

Hence, we can conclude that the dog has week dieting for 19 weeks and lost 9.5 pounds.

Answer:

25%

Step-by-step explanation:

Given that,

The cost price of a cow, CP = $200

Gain = $50

We need to find the gain percentage of the cost price.

SP = CP + gain

= 50 + 200

= $250

[tex]\text{Gain}\%=\dfrac{\text{Gain}}{CP}\times 100\\\\=\dfrac{50}{200}\times 100\\\\=25\%[/tex]

So, the gain percent is 25%.
