Step-by-step explanation:

Step one:

given

Price

[tex]P= -20x^2+1800x[/tex]

where P is the maximum profit

           x is the price of one shirt

Step two:

To rewrite the expression let us first divide through by 20

[tex]P= \frac{-20x^2}{20} +\frac{1800x }{20}\\\\P=-x^2+90x[/tex]

Factoring x out we have

[tex]P=-x^2+90x\\\\P=x(-x+90)[/tex]

Hence the rewritten expression equation for the price is

P=x(-x+90)

Answer:

g = 5c

5*c = g

g/5 = c

Step-by-step explanation:

g = grandfather

c = carl

Answer:

The age of Carl's grandfather is a composite number.

Carl's age is a factor of the age of his grandfather.

The number 5 is a factor of the age of Carl's grandfather.

Step-by-step explanation:

If two bags of bird seed are used to fill these three bird feeders, then we can say that;

2 bags of bird seed = 3 bird feeders

To know the amount of bird seed that each feeder use, we will say;

x bags of bird seed = 1 bird feeder

Equating both postulates and solving

2 bags of bird seed = 3 bird feeders

x bags of bird seed = 1 bird feeder

Cross multiply

3 * x = 2 * 1

3x = 2

subtract 2 from both sides

3x - 2 = 2-2

3x - 2 = 0

Hence model that represents the situation us 3x - 2 = 0 where x is the number of bird seed that each feeder use.

Next is to solve for x;

3x - 2 = 0

3x = 2

x = 2/3

Hence each feeder used 2/3 bird seed

Answer:

The rule is

x + y ≤ 10

Step-by-step explanation:

Here, we want to write a rule that can help get solutions for the individual work hours

The number of hours for car wash is x while the number of hours for mowing lawns is y

Since he cannot work more than 10 hours, he can still work less than 10 hours

What we just have is that the addition of both working hours must not be over 10

So the rule to write is;

x + y ≤ 10

Answer:

184in

Step-by-step explanation:

Since the scale for the statue is 3 inches to 100 feet, we can say 3:100 as a ratio.

To find approximately 305 feet you must divide 305 by 100.

100 can go into 300 evenly 3 times. Since the ratio is 3:100 you should multiply how many times the 100ft fit into the 300ft and the 3in (3 x 3) which is about 9in.

One way we can do this is to divide the hight of the Statue by the model height:

305ft 20in = 15.25ft 1in or 184in (12in per foot).

And so for every inch of the model, it represents 15.25 feet.

For 305 it would be

Answer:

You can fill 11 containers.

Step-by-step explanation:

This problem is asking you to divide 24.75 pounds among 2.25 pound holding containers.

So all you must do is divide 2.25 by 24.75. This leaves us with a quotient of 11.

Step-by-step explanation:

5(2) +2(3) = 10 +6 =16

3(2) + 2(3) = 12

Answer:

X represents the value you can multiply with the slope to get the answer.

y = 0.007x

  = 0.007(6)

  = 0.042

Therefore, 0.042 inches of rain falls in 6 minutes.

Step-by-step explanation:

The circumference of the circle is 105 in to the nearest tenth.

The circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.

The circumference of the circle = 2πr

We are given that the radius of a circle is 16.7 in.

We need to determine the circumference to the nearest tenth.

Radius r = 16.7

Then circumference of the circle = 2πr

= 2 x 3.14 x 16.7

= 104.87

Therefore, the circumference of the circle is 105.

#SPJ2

Answer: 20

Step-by-step explanation:

From the question, to make the punch recipe, the following are needed:

Ginger Ale - 40%

Orange Juice - 25%

Pineapple juice - 20%

Sorbet - 15%

Since we are told that Elise doesn't like sorbit, so she omits that ingredient and adds 5 percent to each of the other ingredients. The the new percent will be:

Ginger Ale - 40% + 5% = 45%

Orange Juice - 25% + 5% = 30%

Pineapple juice - 20% + 5% = 25%

Sorbet - 15% - 15% = 0

To get the total cups of punch that'll be used, let it be represented by y. Therefore,

30% of y = 6

30/100 × y = 6

0.3 × y = 6

0.3y = 6

y = 6/0.3

y = 20

Therefore, she'll have 20 cups of punch.

Answer: (-1.5, 2) and (-1.5, -3.5)

Step-by-step explanation:

The distance between two points (a, b) and (c, d) is:

D = √( (a - c)^2 + (b - d)^2)

A simpler case, is when we have two points where one of the components is the same for both of them, like:

(a, b) and (a, c)

Then the distance will be:

D = √( (a - a)^2 + (b - c)^2 ) = Ib - cI

Then we need to look for points that have an equal component, and the difference between the other two components is exactly 5.5

The solution will be:

(-1.5, 2) and (-1.5, -3.5)

Where the x-component is the same in both of them, then the distance will be:

D = I2 - (-3.5)I  = I2 + 3.5I = 5.5
