Let's assume the original speed with or without, is around 82 miles, within 2 hours.

So in this case, it'd be half the miles, half the hours!

If all movies took the same time to download (unlikely), you could download (5 1/4) / (1 2/5) movies

= (21/4) / (7/5) = (21/4)*(5/7) = 15/4 = 3 3/4 movies.

If it takes 1 2 5 hours to download 1 movie, then in 5 1 4 hours, you will download 4 movies.

-56mi in 4 minutes is (56mi/4) in 1 minutes = 14mi/minute.

Therefore, the submarine was 14 miles below sea level after 1 minute.

Answer:

The submarine's depth relative to sea level after the first minute is -14 miles.

Step-by-step explanation:

Consider the provided information.

Starting at sea level, a submarine descended at a constant rate to a depth of −56 mile relative to sea level in 4 minutes.

This can be written as:

[tex]-56\ miles=4\ minutes[/tex]

To find the submarine's depth relative to sea level after the first minute, divide both the sides by 4.

[tex]\frac{-56}{4}\ miles=\frac{4}{4}\ minutes[/tex]

[tex]-14\ miles=1\ minutes[/tex]

Hence, the submarine's depth relative to sea level after the first minute is -14 miles.

B) The consumer pays less per item.

If a bag of chips cost .15, but if 20 bags cost $2, you are saving $1.

Hope I helped!

Good Luck!

Answer:

B.) The consumer pays less per item

Step-by-step explanation:

If you buy items in bulk, you will pay a higher total price but a lower price per item. For instance, buying a package of four rolls of paper towels will usually be cheaper than buying one roll four times.

(gog)(-3) basically means g(g(-3)).

g(-3) = (-3)^2 - 3(-3) - 6

perimeter = 4m + 3

the perimeter is the sum of the 3 sides of the triangle, thus

perimeter = 3m + 4 - m + 2m - 1 = 4m + 3

Answer: 4m + 3

Step-by-step explanation:

This is because the perimeter of a triangle is the same as adding all of its sides.

3m+(4-m)+(2m-1)

Group like terms:

(3m-m+2m) + (4-1)

Then combine like terms to get your final answer of:

4m + 3

Hi, here is the solution...

The Fibonacci series  1, 1, 2, 3, 5, 8, 13, 21, 34...

3rd number = Sum of the first two numbers.

2 = 1 + 1

4th number = Sum of the two numbers before it

That is, 3 = 2 + 1

5th number is 5.

5 = 3 + 2 (Sum of the two numbers before 5).

6th number is 8

8 = 5 + 3

7th number is 13

13 = 8 + 5

8th number is 21

21 = 13 + 8

Therefore, the conjecture is " Each number in the series is The Sum of Two Numbers Before it."

Hope you understand the concept.

Answer:

The value that optimizes this inequality is x = 1, since it represents the vertex of the parabola. Therefore, $ 0.25 is the price that must be discounted to maximize revenues

With x = 1 the value of the new income will be = $ 1983.75

Step-by-step explanation:

Revenue with the current sale price is:

6 * 330 = $ 1980

Let's call x the number of times the price of a sandwich decreases, that is, if x = 1 then the price of the sandwich decreases by $ 0.25

Then, the price would be:

Price = (6-0.25x)

Then, if the price is decreased by a factor of x, then the number of sandwiches sold will increase by a factor of 15x. Therefore the number of clients will be:

Sale = (330 + 15x)

Now we need an equation for income. The income will be equal to the sale price, for the number of sandwiches sold

Income = price * sale

Income = (6-0.25x) (330 + 15x)

In order for this restaurant pricing model to be profitable, the revenues with the new sale price must be greater than the revenues with the sale price of $ 6. So:

New income> current income.

[tex](6-0.25x) * (330 + 15x)> 330 * 6\\ (6-0.25x) * (330 + 15x)> 1980[/tex]

The left side of the inequality represents a parabola:

[tex]-3,750x ^ 2 + 7.5x + 1980> 1980[/tex]

The value that optimizes this inequality is x = 1, since it represents the vertex of the parabola. Therefore, $ 0.25 is the price that must be discounted to maximize revenues

The attached image shows the region that satisfies the proposed inequality and the vertex of the parabola:

[tex]x = \frac{-b}{2a}[/tex]

With x = 1 the value of the new income will be = $ 1983.75

Hello.

The answer is: 24

length=3*width, this can be written as 3w

area=27 sq cm

Formula for the area of a rectangle=27 (area)= 3w (length) * w (width)

27=3w^2

then divide both sides by 3: 9=w^2

take the square root of both sides to get: w=3

Now that we know what the width is, we can substitute that and find the length: 3w= 3*3=24

None of them are equivalent to 0.3, unless it's 0.3 with a bar over the 3, in which case the answer is 1/3.

Solution:

Convert all the numbers to decimal form;

1/3 = 0.3 (where 3 is recurring)

33/100 = 0.33

5/6 = 0.83 (where 3 is recurring)

2/3 = 0.6 (where 6 is recurring)

The correct choice is  1/3 since its the only choice that don't give a limitation on rounding up the decimal value to 1 decimal place.

Answer:

dont listen to answer above me, its supposed to be in slope intercept form, so it is y=4/3x-1/3

and so we have (4,5)

substitute it in and you will have

y=4/3x+b

5=4/3(4)-b

which is

5=16/3-b

b is equal to 1/3

so thats the y int

so the equation will be

y=4/3x-1/3

The equation of the proposed bike path would take a similar form to the railroad track (y = mx + c) but adjusted to pass through the point (4,5). Without knowing the slope or y-intercept of the original line (railroad tracks), we cannot provide a specific equation for the bike path.

This Mathematical question pertains to the concept of linear equations in coordinate geometry. The problem involves finding the equation of a line that is parallel to the given railroad tracks and denoted as a two-dimensional path. We don't have information on the slope or y-intercept of the railroad tracks in the question, so for the time being, let's assume that the equation of the railroad track line is y = mx + c where m is slope and c is y-intercept.

Any line parallel to y = mx + c will have the same slope 'm'. The given point (4,5) on the new bike path. Hence the equation of the new bike path will be y - 5 = m*(x - 4). We are unable to provide a specific equation without more details about the railroad tracks line.

35/5= 7

so,

4*7 = 28                          1*7= 7

The answer is  28:7

To share $35 in the ratio 4:1, Person 1 will receive $28 and Person 2 will receive $7.

To share $35 in the ratio 4:1, we first need to find the total number of parts in the ratio by adding the two numbers together: 4 + 1 = 5. Next, we divide the total amount of money ($35) by the total number of parts (5) to find the value of each part: $35 / 5 = $7. Now, we can multiply the value of each part by the corresponding ratio values to find the amount of money each person will receive:

Therefore, in the ratio 4:1, Person 1 will receive $28 and Person 2 will receive $7.

27 x $42 = $1,134

The logic of a conditional statement ('if-then') is followed here. Given 'If Kyle is from Texas, then he is a football fan' and 'Kyle is from Texas', we can validly conclude 'Kyle is a football fan'.

The statement 'if Kyle is from Texas then he is a football fan' is known as a conditional statement in logic. Conditional statements have an 'if' part (the hypothesis) and a 'then' part (the conclusion). In this case, the hypothesis is 'Kyle is from Texas' and the conclusion is 'he is a football fan'. The statement 'Kyle is from Texas' confirms the hypothesis. Therefore, following the logic of the conditional statement, we can conclude that 'Kyle is a football fan'. This conclusion is based on the given condition, in real life, of course, being from Texas doesn't automatically make someone a football fan, but within the confines of this logic, it does.

The correct answer is A) as the x values go to positive infinity, then the graph goes to negative infinity.

We can tell this by looking at the graph values as x goes up. You'll notice, as we get higher and higher, the graph disappears down. This means it is heading towards negative infinity for the rest of the graph.

The statement  which is true about the end behavior of the graphed function is:

We know that the end behavior of the function is the value where it approaches when x tends to plus infinity and minus infinity.

 From the graph of the function we see that the graph first decreases continuously and then it increases and again it decreases to minus infinity.

Also,

when x → -∞ we see that  f(x) → ∞

and when  x → ∞ then f(x) → -∞

As the function has opposite behavior in both the directions this means that the function is odd.

At x=0 the value of function is: -2
