Theo bought two hot dogs and two sodas for $4.00. At the same concession stand, Vicky bought three hot dogs and a soda for $4.50. What is the price of a hot dog at the concession stand?
Answers
Soda @ $3.00
If Theo bought two hot dogs and two sodas for $4.00. At the same concession stand, Vicky bought three hot dogs and a soda for $4.50. Then $1.125 is the price of a hot dog at the concession stand
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Theo bought two hot dogs and two sodas for $4.00.
Let hot dogs denoted by H
Soda denoted by S
2H+2S=4...(1)
Vicky bought three hot dogs and a soda for $4.50
3H+S=4.50..(2)
Multiply (2) with 2
6H+2S=9..(3)
Now subtract 3 from 1
2H+2S-6H-2S=4.50-9
-4H=-4.5
H=1.125
Now plug in H value in 2
3(1.125)+S=4.5
3.375+S=4.5
S=4.5-3.375
S=1.125
Hence $1.125 is the price of a hot dog at the concession stand

Find the value of X. If your answer is not an integer, leave it in simplest radical form. The diagram is not drawn to scale. Please show steps.
Answers
Tan(α)=Opposite leg/Adjacent leg
The angle α is 60°, so the opposite leg is "x" and the adjacent leg is 5.
2. When you substitue these values, you have:
Tan(α)=Opposite leg/Adjacent leg
Tan(60°)=x/5
x=(5)(Tan(60°)
x=5√3
Then, the answer is: The value of "x" is 5√3

It is described in the problem statement as "a cost for every one-tenth of a mile traveled." It is described in the table header as "Mileage Cost in Dollars."
The only value in the "Mileage Cost in Dollars" column is 1, which corresponds to a distance of 1/10 mile. So, it appears the numerical value of "the other cost" is $1 for each tenth-mile traveled.

The problem statement does not make clear whether the desired answer is the description of the other cost, or its numerical value.

The surface area of a square pyramid is 136 square inches. The base length is 4 inches. What is the slant height?
Answers
The side length of the base is 4. Find the surface area of the base only by squaring the side length - 4² - which is 16. The surface area of the base is 16 in².
The surface area of the entire pyramid can be found using this equation:
[tex]SA = B + \frac{1}{2} nbl[/tex]
Where:
- SA is the surface area (136 square inches)
- B is the area of the base (16 square inches)
- n is the number of triangles (4, because it's a square pyramid)
- b is the base length (4 inches)
- l is the slant length
Note that we have many parts of this equation, and all we need is the slant length. So, let's format the equation with what we have:
[tex]136 = 16 + \frac{1}{2} * 4 * 4 * l[/tex]
So then we want to solve for l, the slant height. So, start by subtracting 16 from each side. This would give us:
[tex]120 = \frac{1}{2} * 4 * 4 * l[/tex]
Now, multiply both sides by 2 to get rid of the fraction:
[tex]240 = 4 * 4 * l[/tex]
Finally, divide both sides by four, twice (divide by 16):
[tex]15 = l[/tex]
So, we know that the slant height of this pyramid is 15 inches.
This is an ADDMATHS QUESTION so I'm not sure if anyone can help me but please try to ㅠ ㅠ: Find the equation of the normal to the curve y=ln(2x^2 - 7) at the point where the curve crosses the positive x-axis. Give your answer in the form ax+by+c=0 , where a, b and c are integers.
Answers
We find the positive zero-crossing at x=2, and the slope of the curve at that point to be 8. Thus the line will have slope -1/8 and can be written as
.. x +8y -2 = 0
First, take the derivative of the equation given:
[tex]y = ln(2x^2-7)[/tex]
[tex]y' = \frac{4x}{2x^2-7} [/tex]
At 2, the function has a derivative of 8 (just plug in 2 to y'). So, the perpendicular to that has to have the slope -1/8 because of the negative-inverse rule. We have this until now:
[tex]y = -\frac{1}{8}x -2[/tex]
Now, we have to get a 0 on the right side, so, just get everything on the other side, and you are done.
There were n signers of the Declaration of Independence. The youngest was Edward Rutledge, who was x years old. The oldest was Benjamin Franklin, who was y years old. X is 25% of 104, 7 is 10% of y, and n is 80% of y. Y is what percent of (n+y-x)?
Answers
Y= 7/.10 Y=70
N= .8 x 70 N=56
n+y-x 56+70-26=100
70/100 = .7 or 70%
The answer is: Y is 70% of (n+y-x)
Answer:
70%
Step-by-step explanation:
First we calculate X using the following formula:
X = 25/100 * 104
X = 0.25 * 104
X = 26
Then we calculate Y using the following formula:
7 = 10/100 * Y
7 = 0.1 * Y
7/0.1 = Y
Y = 70
Then we calculate N as per the formula below:
N = 80/100 * Y
N = 0.8 * 70
N = 56
Finally using the formula mentioned in question we derive Y what percent of N + Y - X:
= Y/ (N + Y - X) * 100
= 70/ (56 + 70 - 26) * 100
= 70/100 * 100
= 70%

Rick discounts a 100-day note for $25,000 at 13%. The effective rate of interest to the nearest hundredth percent is
A. 13.48%.
B. 13.03%.
C. 13.02%.
D. 13.49%.
Answers
= 25,000 x 0.13 x (100/365)
= 902.78
This will be deducted from the principal amount, which is 25,000.
= 24,097
Last, we plug our values in to the effective rate formula for interest:
[tex] \frac{Interest}{Proceeds x Time of Note} [/tex]
902.78/6693.6722
= 13.487066
After rounding, we come to our final answer, which is D, 13.49%.

Find the percent markup from wholesale cost to selling price.
Answers
Answer:
$650 - $200 = $450
$200 = p × $450
p = 20/45 = 4/9 = about 44%
The percent markup is about 44%.
To find the percent markup from wholesale cost to selling price, calculate the difference between the selling price and the wholesale cost, divide that difference by the wholesale cost, and multiply by 100.
Explanation:To find the percent markup from wholesale cost to selling price, you need to calculate the difference between the selling price and the wholesale cost, and then divide that difference by the wholesale cost. Finally, multiply the result by 100 to get the percent markup.
For example, if the wholesale cost is $50 and the selling price is $75, the difference is $25. Dividing $25 by $50 gives you 0.5, and multiplying by 100 gives you a 50% markup.
