1b. 6.4*10^7 +0.54*10^7 = 6.94*10^7 . . . . square miles
.. yes, we can find the same answer this way
2. The ratio of areas is 6.4*10^7/(5.4*10^6) ≈ 11.85
The Pacific Ocean is about 12 times the size of the Arctic Ocean.
The difference of areas is 6.4*10^7 -0.54*10^7 = 5.86*10^7
The Pacific Ocean is 5.86*10^7 square miles larger than the Arctic Ocean.

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.

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

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%.

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:

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%

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.
