If a car travels 400 miles in 4 hours how fast is it going?

State B with the second-lowest population has the lowest population density. Then the correct option is B.

The process of making choice is by identifying the correct decision, gathering information, and assessing alternative solutions.

The second-lowest density for the states will be given as

[tex]\rm D_A = \dfrac{1055173}{2677} = 394.16[/tex]

[tex]\rm D_B = \dfrac{1333089}{36418} = 36.61[/tex]

[tex]\rm D_C = \dfrac{3596677}{5543} = 648.87[/tex]

[tex]\rm D_D = \dfrac{6745408}{10555} = 639.07[/tex]

Thus, state B with the second-lowest population has the lowest population density. Then the correct option is B.

The lemon should be sold 3 days from now to maximize profit, which would be $894.80.

Given that a Super Lemon currently weighs 100 kg and is increasing by 4 kg per day, and the price for Super Lemon’s is currently $8.90 per kg but is decreasing at $0.30 per day, and the cost to grow the lemon is $0.80 per day, to determine how many days from now the lemon should be sold to maximize profit and what the maximum profit will be, you should perform the following calculation:

Therefore, the lemon should be sold 3 days from now to maximize profit, which would be $894.80.

Answer:

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                      f(x) = a(x - h)² + k

the vertex is (4, -4)  ⇒   h = 4,  k = -4

so:

  f(x) = a(x - 4)² + (-4)

    f(x) = a(x - 4)² - 4

So the right answer is the first one.

Answer:

Step-by-step explanation:

3x^2 + 8x - 16 - SOMETHING = x^2 - 4

Re-arranging left and right:

SOMETHING = 3x^2 + 8x - 16 - x^2 + 4

= (3x^2 - x^2) + 8x - 16 + 4

= 2x^2 + 8x - 12

The equation that best represents the relationship between the number of loaves of bread which is denoted by b and the number of cups of bananas which is denoted by c is c = 2 1/4b.

We know that we need 11 ¼ cups of bananas are needed to make 5 loaves of bread.

We need to divide 11 ¼ to 5 which the answer is 2 ¼. The 2 ¼ represents how many cups are needed to make 1 loaf of bread.

Step-by-step explanation:

When she starts , she does a sit-up every 222 seconds.

But as she gets tired, each sit-up takes longer and longer to do.

It means, each sit-up takes more time than she did at beginning.

So, it is NOT proportional to the time.

If it is proportional, she should take constant number of sit-ups even she get tired.

The value of expression at x = - 5 and y = - 2 is,

⇒ 1/3

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ ([x/(y - 1)](-4) - [xy + (-3)]/ (-1)

Now, We can put x and y in above expression as;

⇒ ([x/(y - 1)](-4) - [xy + (-3)]/ (-1)

⇒ [- 5 / (- 2 - 1) ] (- 4) - [- 5×- 2 + (- 3)] / (- 1)

⇒ [ - 5/- 3 ] (- 4) - [10 - 3] / (- 1)

⇒ - 20/3 + 7

⇒ 1/3

Thus, The value of expression at x = - 5 and y = - 2 is,

⇒ 1/3

[tex]47 = 2(x + 3) + 3(x - 3)[/tex]

[tex]47 = 2x + 6 + 3x + - 9[/tex]

[tex]47 =(2 x + 3x) + (6 + - 9)[/tex]

[tex]47 = 5x + - 3[/tex]

[tex]47 = 5x - 3[/tex]

[tex]5x - 3 = 47[/tex]

[tex]5x = 47 + 3[/tex]

[tex]5x = 50[/tex]

[tex]x = \frac{50}{10} [/tex]

[tex]x = 10[/tex]

Let us check whether or not we have found out the correct value of x by placing 10 in the place of x .

So :-

[tex]47 = 2(10 + 3) + 3(10 - 3)[/tex]

[tex]47 = (20 + 6) + (30 - 9)[/tex]

[tex]47 = 26 + 21[/tex]

[tex]47 = 47[/tex]

As the left hand side of the equation is equal to the right hand side of the equation , we have found out the correct value of x .

Therefore , 47 = 2 ( 10 + 3 ) + 3 ( 10 - 3 ) and x = 10 .

Answer:

C

Step-by-step explanation:

A difference of squares can be factored in general as

a² - b² = (a - b)(a + b)

We are looking for 2 terms separated by a - and perfect squares on either side. The only one meeting this criteria is

25x² - 64y²

= (5x)² - (8y)²

= (5x - 8y)(5x + 8y) ← in factored form

Answer:

A

Step-by-step explanation:

It’s the opposite

Answer:

(multiply both sides by 6)

6×[tex]\frac{4h+4}{6}[/tex]-10×6=-2h×6

(simplify)

4h+4-60=-12h

4h-56=-12h

(move constant to the right side and variable to the left)

4h+12h=56

16h=56

(divide both sides by 16)

h=7/2

Answer:

mode is 16

Step-by-step explanation:

because there are 3 16s which is the most common number in this data set

Answer:

16

Step-by-step explanation:

Your mode would be 16

Your mode is 16 because the mode is the number that appears most in the data set and 16 appears 3 times in the data set.

Here is some extra answers just incase.

median=14.5

Because median is the middle number and because 13,16 are the middle numbers then you split that in middle and plus you also have to sort it least to gretest.

Mean=14.5 also because mean is the average of all the numbers in the data set.

range is 8

Range is the highest number subtracting lowest number so 19-11=8

Minimum is 11

The minimum is the lowest number and the data set so 11

maximum is 19

Maximum is the highest number in the data set.
