Answer:
0 miles
Explanation:
Step 1) -----> 5 miles west
Step 2) <----- 5 miles east
So in conclusion I think that the man came back to where he started.
Compass:
N
W E
S
Answer:
15 miles.
Step-by-step explanation:
5 + 10 = 15
5 represents the fact that he walked 5 miles east, and then if he were to walk from there towards the west, that would be 10 miles because if its 5 miles from his starting point to the east, then it would be double from the east to the west so if you add 5 miles and 10 miles, you should get a total of 15 miles.
I hope this helps you :D
Traditionally, the earth's surface has been modeled as a sphere, but the World Geodetic System of 1984 (WGS-84) uses an ellipsoid as a more accurate model. It places the center of the earth at the origin and the north pole on the positive z-axis. The distance from the center to the poles is 6356.523 km and the distance to a point on the equator is 6378.137 km.
A) Find an equation of the earth's surface as used by WGS-84.
B) Curves of equal latitude are traces in the planes z = k. What is the shape of these curves?
C) Meridians (curves of equal longitude) are traces in planes of the form y=mx. What is the shape of these meridians?

Step-by-step explanation:
y = (x – 6)2 - 4
Find the inverse
Answer:
y = (x + 16)/2
Step-by-step explanation:
y = (x - 6)2 - 4 Switch the x and y variables
x = (y - 6)2 - 4 Solve the (y - 6)2
x = 2y - 12 - 4 Combine like terms
x = 2y - 16 Isolate the y variable
x + 16 = 2y
y = (x + 16)/2 <----- This is your answer

A series of books is published at 4-year intervals. When the fifth book is issued, the sum of the publication’s years will be 10,020. When was the first books published?
Answer:
The first book was published in 1816.
Step-by-step explanation:
A series of books is published at 4-year intervals.
This means that:
The first book is published at year x.
The second book is published at year x + 4.
The third book is published at year x + 4 + 4 = x + 8
The fourth book is published at year x + 8 + 4 = x + 12
The fifth book is published at year x + 12 + 4 = x + 16
When the fifth book is issued, the sum of the publication’s years will be 10,020.
This means that:
[tex]x + x + 4 + x + 8 + x + 12 + x + 16 = 10020[/tex]
[tex]5x + 40 = 10020[/tex]
When was the first books published?
This is x. So
[tex]5x + 40 = 10020[/tex]
[tex]5x = 9080[/tex]
[tex]x = \frac{9080}{5}[/tex]
[tex]x = 1816[/tex]
The first book was published in 1816.
125% • n=45..............
Answer:
125% = 1.25 x 45 = 56.25
Step-by-step explanation:
First 125% as a decimal is 1.25 and the . means multiply if n=45 so 1.25 x 45 = 56.25
121/2% in to a fraction
9514 1404 393
Answer:
1/8
Step-by-step explanation:
You can replace % with /100 to make it a fraction.
12 1/2% = (12 1/2)/100 = (25/2)/100 = 25/200 = 1/8
__
Or, you can reduce the decimal fraction.
12.5% = 12.5/100 = 0.125 = 125/1000 = 1/8
3x - 2(6 - x) = 7x + 2(5 + x) - 6
What is the answer
Answer:
x= -4
Step-by-step explanation:
Answer: x = -4
Step-by-step explanation:
first, we remove the parentheses.
3x - 12 + 2x = 7x + 10 + 2x - 6
then, we cancel equal terms.
3x - 12 = 7x + 10 - 6
then, we calculate.
3x - 12 = 7x + 4
next, we move the terms.
3x - 7x = 4 + 12
then, we collect like terms and calculate.
-4x = 16
finally, we divide both sides.
x = -4

Answer:
1,5
Step-by-step explanation:
Answer:
1.5 minutes
Step-by-step explanation:
If he swims 10 laps in 15 minutes, then the answer can be found with the ratio 15 : 10. Simplifying the ratio, it becomes 1.5 : 1, or 1.5 minutes per 1 lap

Answer:
357.1573 (If you don't round)
Step-by-step explanation:
To find area of a rectangle is to multiply length by width, which in this situation would be 15 by 16.6, which is equal to 249. Next, we need to add this to the area of the semicircle. The area of a semicircle is equal to 1/2 * pi * radius^2 (Because a semicircle is half a circle and a circle's area is pi * radius^2). The radius is equal to half the diameter, which in this case is 16.6. 16.6/2 = 8.3, so the radius is 8.3. If we plug this into the equation, we get that 108.1573 is the area of the circle (If you use 3.14 as pi). 108.1573 + 249 is equal to 357.1573.

Answer:
The solution for the system of equations is (2, 4). This means that for February, both the number of imports and the number of exports was 4.
Step-by-step explanation:
Again, remember that the solutions for a system, in this case two charts, are where the outputs (exports) are the same.
We can see that the exports for both f(x) and g(x) are the same for the month of February (second month).
This means that the solution to our system of equations is (2, 4).
So, the solution means that for the second month February, the number of imports was equivalent to the number of exports: both are 4.
(And lastly, out of the four months given, only February had the same number of imports and exports.)

Step-by-step explanation:
what is the value of 0.48
Answer: 48% 48/100
depends on what you are asking for
Step-by-step explanation:
Answer:
Simplified: (48÷4)(100÷4) = 1225 when reduced to the simplest form. Fraction: 48/100, in simplest form, is 12/25. Percentage: 48%.
Step-by-step explanation:
What percent of 40 is 14?
First translate the question into an equation.
"What percent" means x/100, "of 40" means times 40, "is 14" equals 14.
So we have (x)(40) = 14 or 40x = 14.
Dividing both sides by 40, we find that x = 0.35.
Now, we want to write our answer as a percent.
So we move the decimal 2 places to the right and we have 35%.
Paul says the slope of the line is zero
Phoebe says the slope of the line is undefined
A. Paul
B. Phoebe
Why did you use that answer?
Answer:
B. Phoebe
Step-by-step explanation:
Let's find the slope of the line that passes through (12, 5) and (12, 9).
Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{9 - 5}{12 - 12} = \frac{4}{0} [/tex] = undefined.
14 can't be divided by zero. Therefore, it is concluded that the slope of the line is undefined.
Therefore, Phoebe is correct.
2. Identify the Formula for finding the nth term of an Arithmetic Sequence, where A(n) is the nth term of an Arithmetic Sequence, is the first term, n is the term number and d is the common
difference
A(n) = 2 - 1 + (n - 1)d
A(n) = a + (n - 1)d
A(n) = a + (n)(d - 1)
O A(n) = a + (n + 1)d
Answer:
A(n) = a + (n - 1)d is the correct formula for an arithmetic sequence.

10. Sarah finances $549,000 with a 30/6 balloon mortgage at 5.35%. How much will she pay for principal and interest over the life of the loan? (3 points)
$715,175.04
O $713,297.14
O $717,393.12
O $719,607.40
Answer:
$717,393.12
Step-by-step explanation:
The 30/6 balloon mortgage means that she would make monthly payments for the first six years, while the balance outstanding after 6 years is paid by making one large payment.
The 30 implies that monthly payment should be computed on the basis it is a 30-year mortgage.
Loan amount=monthly payment*(1-(1+r)^-n/r
loan amount=$549,000
monthly payment=the unknown
r=monthly interest rate=5.35%/12=0.004458333
n=number of monthly payments in 30 years=30*12=360
549000=monthly payment*(1-(1+0.004458333)^-360/0.004458333
549000=monthly payment*(1-0.201607475)/0.004458333
549000=monthly payment*0.798392525/0.004458333
monthly payment=549000*0.004458333/0.798392525=$ 3,065.69
Total monthly payments for6 years=$ 3,065.69*12*6=$220,729.68
The ballon payment is the present value of monthly payments for 24 years remaining
Financial calculator:
N=288(24*12)
PMT=3065,69(monthly payment)
I/Y=5.35/12(monthly interest rate)
FV=0(balance after payments is nil)
CPT PV=$496,663.41
Total payments=$496,663.41 +$220,729.68=$717,393.09

Step-by-step explanation:
Jack was 14 years older than Priscilla. Together their ages totaled 158 years. What were their ages?
Answer:
Jack's age: 86, Priscilla's age: 72
Step-by-step explanation:
Priscilla's age can be called x, which makes Jack's x + 14. We know that their added ages total 158 years which means that x + x + 14 = 158, which means that 2x + 14 = 158. We can then solve this by subtracting 14 on both sides and getting 2x = 144. We can divide on both sides to get that x = 72. Since Priscilla's age is x and Jack's is x + 14, we already know Priscilla's age and we need to find Jacks by adding 14 to 72. 72 + 14 = 86, so Jack's age is 86.
Answer:
Jack is 86 years old,
and Priscilla is 72 years old
Step-by-step explanation:
j = Jack
p = Priscilla
j - 14 = p $\Rightarrow$ j = p+14
j+p = 158
By subsituting the value of j ( first equation) into the second equation, we get:
p+14+p = 158
2p+14 = 158
2p = 144
p = 72.
So, j = 86
