Louise owns a hot dog stand. The amount of money she collects from selling hot dogs each day can be found by using the equation y=3.5x What does 3.5 from the equation represent in the situation?

Answers

Answer:

3.5 represents the cost of each hotdog ($3.50).

Step-by-step explanation:

In y = 3.5x, the x represents the number of hotdogs and the y represents the total amount you have to pay for those hotdogs. The 3.5 represents the cost of each hotdog.

3.5 (3.50$)is how much each hotdog cost

A small pot holds 75% as much as a large pot.


If a small pot holds 36 units, how much does the large pot hold?

Answers

Answer:

63 units!!

Step-by-step explanation:

36x.75= 27

Add 27 to 36 to get the large pot.

Answer:

The large pot can hold 48 units of water.

Step-by-step explanation:

small pot holds 75% water of a large pot

small pot holds 36 units

let x be quantity of water in large pot

According to the question,

75% of x = 36 units

75/100 * x= 36

75x/100= 36

75x= 36*100

75x= 3600

x= 3600/75

x= 48 units

The large pot can hold 48 units of water.

Answers

Answer:

b = -2

Step-by-step explanation:

 

if y =mx +b then b is -2 because you’re given the points; (-2,4) and (6,b) which means that you have to solve for x1-x2/y1-y2 which will get you to -2-6/4-b which is -8/4-b and then you would want to isolate b to find the answer which means you would have to multiply both sides by -b and -8/4=-2 so that’s the answer

The sum of twice a number and 13 is 47. Find the number.

Answers

Answer: 17

Step-by-step explanation:

In this problem, the phrase "a number" can be interpreted as a variable.  In this case, let the variable be "x."

Thus, "twice a number" = "2x"

"and 13" = "+ 13"

"is 47" = "= 47"

Thus, the problem is simply 2x + 13 = 47.

Then, simply subtract 13 from both sides to get 2x = 34.

Then, simply divide both sides by 2 to get x = 17.

Because "the number" is "x," the number is 17.

Answers

Answer:

X=1.5, but I may be incorrect, hope this helps!

Step-by-step explanation:

FACTS I KNOW:

X has to be less than 2 but greater than 1

Angle B and D are 90 degrees

The complete bottom side is equal to 10

All triangle angles add up to 180 degrees

All angles in rectangles and squares are 90 degrees

All rectangles have 2 sets of 2 of the same sides.

If you take a piece of the top right you could make a rectangle

It would take about .5 of the 2

Therefore X=1.5 approximately, but I may be wrong.

20 (boys) the mean was 62% so times that by 20 it will give me 1240 marks.

After that do 30x70 so number of students times the 70% mean which gives 2100.

Now take the 2100 - 1240 = 860.

After that 860/10 = 86%

20 boys get 62 and 10 girls get 86 this all will equal to 2100.....2100/30 = 70

So the final answer is 86%

Answer:

y = -180 + 3x

Step-by-step explanation:

Because AB = AC -> ABC is a isosceles triangle -> B = C

Because AB = BD -> ABD is an isosceles triangle -> A = D -> x = D

We have ADB + ADC = 180 -> x + ADC = 180 -> ADC = 180 - x (1)

We have x = D, and BAD + ADB + ABD = 180 -> ABD = 180 - 2x but B = C -> C = 180 - 2x (2)

With (1) and (2) We have DAC + ACD + ADC = 180

-> y + 180 -2x + 180 -x = 180

-> y + 360 - 3x = 180

-> y = -180 + 3x

y=3x-180

For a function, each x term must correspond to exactly one y term. We can use the vertical line test to determine whether or not that holds true for the following 6 graphs. If each x term corresponds to exactly one y term, then any vertical line that we draw on the graph should hit the graph at only one point.

1. We can't draw a vertical line that hits the graph at more than one

point so this relation must be a function.  

2. We can draw many vertical lines that will hit the graph at more than one point. Thus, we can conclude the graph shown here is not a function.

Question 2: ARITHMETIC SEQUENCES AND SERIES
Tamara has decided to start saving for spending money for her first year of college. Her money is currently in a large suitcase under her bed, modeled by the function s(x) = 450. She is able to babysit to earn extra money and that function would be a(x) = 6(x − 2), where x is measured in hours. Explain to Tamara how she can create a function that combines the two and describe any simplification that can be done.

Question 4: GEOMETRIC SEQUENCES
Tommy has $350 of his graduation gift money saved at home, and the amount is modeled by the function h(x) = 350. He reads about a bank that has savings accounts that accrue interest according to the function s(x) = (1.04)^x−1. Explain how Tommy can combine the two functions to model the total amount of money he will have in his bank account as interest accrues after he deposits his $350. Justify your reasoning.

Answers

Answer:

Question 2: The first function represents the amount of money she'll have from her 450 under her bed.

s(x) = 450

The second function represents the amount of money she'll earn from babysitting per hour (x):

a(x) = 6(x - 2)

To figure the combined amount, we can add the two functions:

f(x) = s(x) + a(x)

f(x) = 450 + 6(x - 2)

From there, she can simplify the function by distributing, then combining the like terms to simplify:

f(x) = 450 + 6x - 12

f(x) = 438 + 6x

Answer:

f(x) = 438 + 6x

Question 4: His functions are;

h(x)=$350

s(x)=(1.04)^x-1

To find total amount of money in Tommy's account using the functions above, we substitute the first equation x=$350 in the second function.

Answer:

B) 28 inches.

Step-by-step explanation:

After 1/8 of a ribbon is thrown away, the remaining part is cut into two pieces whose lengths are in the ratio 4 : 5.

And we want to find the length of the shorter ribbon from the two remaining pieces.

We are given that 9 inches of the original ribbon was thrown away. Since this is 1/8 of the total length, we can write that:

[tex]\displaystyle \frac{1}{8}L=9[/tex]

Where L represents the total length of the ribbon.

Solve for the total length:

[tex]\displaystyle L=72\text{ inches}[/tex]

So, the original length of the ribbon was 72 inches.

Since we threw away 9 inches of it, we now only have 63 inches.

This is then cut into two pieces in a ratio of 4 : 5. Let x represent the constant. Thus:

[tex](4x)+(5x)=63[/tex]

Solve for x:

[tex]9x=63\Rightarrow x=7[/tex]

Hence, the two remaining ribbons measure 28 inches and 35 inches.

Therefore, our answer is B.
