Answer:
The spacecraft would weigh 500 kilograms on Titan.
Step-by-step explanation:
An object that weighs 105 pounds on Earth would weigh 15 pounds on Titan.
This means that the weighs on Titan are 105/15 = 7 times less than the weighs on Earth.
How much would a spacecraft that weighs 3500 kilograms on Earth weigh on Titan?
3500/7 = 500 kilograms
The spacecraft would weigh 500 kilograms on Titan.

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.
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%.

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

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

The area of triangle ABC is 4 root 2. Work out the value of x
Answer:
x ≈ 2.4
Step-by-step explanation:
Area of the triangle = 1/2 absin theta
Find the diagram of the triangle attached
a = 2x-3
b =x+2
theta = 45°
Substitute and find x
4√2 = 1/2(2x-3)(x+2)sin45
8/√2 = (2x-3)(x+2)(1/√2)
8 = (2x-3)(x+2)
Expand
8 = 2x²+4x-3x-6
2x²+x-6-8=0
2x²+x-14 = 0
x = -1±√1²-4(14)(2)/2(2)
x = -1±√1+112/4
x = -1±√113/4
x = -1+10.63/4
x = 9.63/4
x = 2.4
The value of x is 3.075.
Given that,
The area of the triangle is [tex]4\sqrt{2}[/tex] square meter,
and [tex]\theta[/tex] is 45 degrees.
The one side of the triangle is (2x-3) and the other side of the triangle is (x+2).
We have to determine
The value of x.
According to the question
The area of the triangle is determined by the following formula,
[tex]\rm Area \ of \ triangle = \dfrac{1}{2} sin\theta[/tex]
Substitute all the values in the formula
[tex]\rm Area \ of \ triangle = \dfrac{1}{2} absin\theta\\\\4\sqrt{2} = \dfrac{1}{2} (2x-3)(x+2) sin45\\\\2\times4\sqrt{2} = (2x^2+4x-3x-6)\dfrac{1}{\sqrt{2} }\\\\\sqrt{2} \times8\sqrt{2} = (2x^2+x-6)\\\\8\times2 = (2x^2+x-6)\\\\16 = 2x^2+x-6\\\\2x^2+x-6-16=0\\\\2x^2+x-22=0\\\\x = \dfrac{-b\pm\sqrt{b^2-4ac} }{2a}\\\\x = \dfrac{-1\pm\sqrt{(-1)^2-4\times2\times(-22)} }{2\times2}\\\\x = \dfrac{-1\pm \sqrt{177} }{4}\\\\x = \dfrac{-`1\pm13.30 }{4}\\\\[/tex]
[tex]\rm x = \dfrac{-1+13.30}{4} \ and \ x = \dfrac{-1-13.30}{4} \\\\x = \dfrac{12.30}{4} \ and \ x= \dfrac{-14.30}{4}\\\\x = 3.075 \ and \ x = -3.575[/tex]
The value of x can not be negative so the value of x is 3.075.
Hence, The required value of x is 3.075.

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.)

Sara has 2 pounds of chicken. She uses 5 ounces of chicken while cooking. How can you determine the mass of chicken that she has left?
Answer: 27 ounces of chicken.
Step-by-step explanation:
Sara has 2 pounds of chicken.
She uses 5 ounces of chicken.
So now, she has:
(2 pounds - 5 ounces ) of chicken.
To perform this subtraction, we first need to write bot quantities in the same units.
First, we know that:
1 pound = 16 ounces.
Then we can rewrite 2 pounds, this is equal to 2 times 16 ounces.
2 pounds = 2*16 ounces = 32 ounces.
Then initially she has 32 ounces, and she uses 5 ounces.
Now she has:
(32 ounces - 5 ounces) = 27 ounces of chicken
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?

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
Paul says the slope of the line is zero

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.
