Answer: the rate at which its altitude is changing is -47 ft/s
Step-by-step explanation:
Given that;
ds/dt = 45 mph = 45 × 5280/3600 = 66 ft/sec
no we have to determine dx/dt
so
cos∅ = dx/dt / ds/dt
cos45° = dx/dt / 66
dx/dt = 0.7071 × 66
dx/dt = 46.6686 ≈ 47 ft/s ( as altitude is decreasing, its negative - )
so the rate at which its altitude is changing is -47 ft/s

Rewrite in simplest terms: -2(3g-8g+8)-9g−2(3g−8g+8)−9g
Answer: 2g - 32
Step-by-step explanation:
-2 (3g - 8g + 8) - 9g - 2 (3g - 8g + 8) - 9g
First step is to use the distributive property to distribute 2.
The expression is now:
-6g + 16g - 16 - 9g - 6g + 16g - 16 - 9g
Now you put the like terms together..
-6g + 16g - 9g - 6g + 16g - 9g -16 - 16
All that is left to do is combine them!
(-6g + 16g - 9g - 6g + 16g - 9g) + (-16 - 16)
2g + (-32)
2g - 32
Hope that helped!

A store owner paid $15 for a book. She marked up the price of the book by 40% to determine its selling price.
A.) What is the selling price, in dollars, of the book?
B.) A customer buys a different book that has an original selling price of $38. The book is discounted 25%. The customer must pay a 6% sales tax on the discounted price of the book. What is the total amount, in dollars, the customer pays for the discounted book?
Answer:
First, find 75% of 38. Then multiply that number by 1.06. That should give you the answer. Your welcome if your still confused just answer back!

If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy with blue eyes, what is the probability that a fraternal twin will transmit the blue eye allele to his or her offspring
Answer:
50 percent
Step-by-step explanation:
It is given that one of the parent with a dominant trait have brown eyes and the other parent with a recessive trait has blue eyes. They produce a twin boy with eyes that is blue in color. So the probability of the fraternal twin to transmit his allele of blue eye to his or her offspring is 50 percent.
And also the probability of the offspring to pass the allele on to his or her offspring is 50 %.
The product rule is used : 0.5 x 0.5 = 0.25 or 25%.

my teacher would like you to solve this using fraction ex:(345/x=727/2355) (just a heads up!!) please help :)
Answer:
84
Step-by-step explanation: (edited)
52% problems are pointless i.e. 48% are NOT pointless.
Recall that 1% = 1/100.
Therefore 48% = 48/100 = 12/25.
Let x be the number of problems that are not pointless.
x/175 = 12/25
x = 84
Answer:
84
Step-by-step explanation:
According to the question
175×48%
175×48/100
7×48/4
7×12
84

Explain answer
Will give braisnlt
Answer:
There are no solutions
Step-by-step explanation:
No intersections or points that apply for the equations.
Any intersection between both lines is a solution. As these lines are parallel they have no solution. If they met at any point, 90 degree or not, there is solution, the solution will be a point. If they are on the same line, hitting all the same points, the solutions are infinite.

SOMEONE PLEASE HELP!!! THIS IS MY LAST QUESTION!!!
Answer:
The answer to the question provided is 30.
Step-by-step explanation:
[tex] \frac{18}{27} = \frac{20}{x} \\ \\ \frac{540}{18} = \frac{18x}{18} \\ \\30 = x[/tex]
Happy to help!
=====================================================
Explanation:
Due to the parallel lines, we have two similar triangles. So the sides are proportional.
18/27 = 20/x
2/3 = 20/x
2x = 3*20
2x = 60 .... cross multiply
x = 60/2
x = 30
---------------
Another way you can approach it is to say
18/(18+27) = 20/(20+x)
18/45 = 20/(20+x)
2/5 = 20/(20+x)
2(20+x) = 5*20
40+2x = 100
2x = 100-40
2x = 60
x = 60/2
x = 30
If 4 movie tickets cost $28, how much would it cost to buy 9 movie tickets
Answer:
$63
Step-by-step explanation:
First, divide 28 by 4 to get 7
Now we know that one ticket cost $7.
Do 7 times 9 to get 63
9 tickets costs $63
9 movie tickets would cost $63.
Since 4 movie tickets cost $28, you can divide 28 by 4 to get 7. From here, you can multiply 7 by 9 to get 63.

Answer:
Problem 1: No
Problem 2: Yes
Step-by-step explanation:
Problem 1:
{(-2, 1), (-2, 3), (0, -3), (1, 4), (3, 1)}
This relation is not a function because there are two y-values, 1 and 3, related to one x-value, -2.
Thus, for a relation to be a function, every x-value must be related to exactly 1 y-value.
Problem 2:
{(0, 2), (3, 4), (-3, -2), (2, 4)}
In this relation, each x-value (domain) has exactly one y-value (range) that it is related to. Therefore, this is a function.
Find the x-Intercept and the y-Intercept of the line below. Click on "None" if applicable.
None
Answer: X-intercept is (2,0)
Y-intercept is (0,-2)
Step-by-step explanation:
Answer:
X-intercept is (2,0)
Y-intercept is (0,-2)
Step-by-step explanation:
The x intercept is the point at which the line hits the x-axis
in this picture, you can see that the given line hit the x-axis at (2,0)
The y intercept is the point at which the line hits the y-axis
so in this case you can see the the line hits the y-axis at (0,-2)
Bonus: if a line is horizontal it will not have an x intercept, and if a line is vertical, it will not have ay intercept
