a skydiver jumps out from the plane at 10,000 feet above the ground. the skydiver decends at a rate of 175 feet per seconds. how high in the air is the skydiver when he opens his parachute after 25 seconds?
Answer:
5625 feet
I hope it's helps you
Answer:
5625 feets
Step-by-step explanation:
Rate(feet/seconds) = height(feets)/time(seconds)
175 = x/25
x = 4375
After the skydiver opens his parachute the height reduces
Initial height – reduced height
10000 – 4375
= 5625 feets
Complete the statements to find the measurements of ∠a and ∠b .
Find the measurement of ∠a.
m∠a +
°=180°
m∠a =
°
Find the measurement of ∠b.
m∠b +
° +
° =180°
m∠b =
°
Answer:
Step-by-step explanation:
We know that a straight angle is equal to 180°. Therefore, 120°+(a)=180°
We can solve for (a) by subtracting 120 from 180, which is 60.
180-120=60
m∠a+120°=180°
m∠a=60°
We know that the sum of all angles in a triangle is 180°.
Therefore, (a)+60°+(b)=180°
We know that (a) is equal to 60°, so our new equation is:
60°+60°+b=180°
60+60=120
180-120=60
m∠b+60°+60°=180°
m∠b=60°

Answer:
The probability is not 4/12 for the red marble, but 4/11
Step-by-step explanation:
Francisco calculated to probability of drawing a yellow marble correctly, but since he isn't replacing it, the amount of marbles in the bag is not 12, but 11. Since there are 4 red marbles, the probability is 4/11

Answer:
1: Tip, $2.23
2: Tax, $0.74
3: Total, $17.87
4: Split, $5.95
Step-by-step explanation:
To find the tip, you must multiply the tip percentage by the bill, (which has not been taxed yet). The tip is 15%, which is equivalent to 0.15. The tip multiplied by the bill (0.15×14.90) equals $2.23.
To find the tax, you do the same as you did with the tip. The tax is 5%, which equals 0.05. The tax multiplied by the bill, (0.05×14.90) equals $0.74. The total cost is the bill, tip, and tax added together, (14.90+2.23+0.74) equals $17.87. To find out how much each person will pay equally, you must divide the total bill by the amount of people, (17.87÷3) which equals $5.95.

I learned how to find the area of a triangle with 2 numbers (0.5*b*h), but how do you find the area with 4 numbers?
Answer:
area =12
Step-by-step explanation: you don't need to use all 4 numbers just used the base which is 8 then times it with 3 which gives you 24 then divided it by 2 which gives you 12.
Answer:
Area=12
Step-by-step explanation:
You take the height which is 3 and multiply it by the base which is 8. Then you get 24 and divide it by 2 which gives you 12.

To the nearest hundredth, what is the surface area that will be painted?
Answer:
6.5in
Step-by-step explanation:
find the area of the shaded regions
fine the surface area of the square
A = 2×2
A = 4
find the area of the triangle
A = 1/2bh
A = 1/2×2×2.5
A = 2.5
add the areas
2.5+4 = 6.5
Skye made a deposit of $625 into an account that earns 4% simple interest for 6 years. How much did Skye earn in interest at the end of 6 years?
Answer:
She will earn 150$
Step-by-step explanation:
4% = 0.04
0.04 x $625 = 25
Now we divide 25 by the number of years, which is 6.
6 x 25 = 150$
Therefore, Skye earns 150$ from interest over the course of 6 years.
You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.
The probability of spinning an odd number, not flipping heads, then not spinning a 6 is
__
Using it's concept, it is found that the probability of spinning an odd number, not flipping heads, then not spinning a 6 is:
[tex]p = \frac{20}{81} = 24.69\%[/tex]
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
There are 5 odd numbers in the spinner, out of 9, hence the probability of spinner an odd number is 5/9.The coin is fair, hence the probability of flipping tails = not heads is of 1/2.Out of the 9 numbers in the spinner, only one is six, hence the probability of not spinning a 6 is of 8/9.Then, the probability of the compound event is:
[tex]p = \frac{5}{9} \times \frac{1}{2} \times \frac{8}{9} = \frac{20}{81} = 24.69\%[/tex]

Answer: A is yes. B is no, C is yes
Step-by-step explanation: The reason A is yes, is because the terms are 27b, 12b and 4 because they are separated. The reason B is no, is because the like terms are 27b and 12b because their variables are alike. The reason C is yes, is because 27b+12b=39b+4 is an équation simplified.

Function 1: None of the Above
Function 2: Quadratic
Function 3: Linear
Step-by-step explanation:
Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.
Function 2: It has a vertex-(6,32)
Function 3: The y-axis goes up at a constant rate of 6.

Help please show work too
Answer:
B
Step-by-step explanation:
I am not sure what your teacher wants but I guess you can say the following:
at n = 1, the cost is 4 dollars.
at n = 2, the cost is 8 dollars.
This trend is the same where the cost increases by 4 as n increases by 1. This means the C = 4n. We can check this by plugging values into the equation.
For the first row, C = 4, n = 1, and so the equation satisfies it. For the second row in the table, C = 8, n = 2, and so the equation works again. The other data points also agree using the equation.

You can find X in an equation by doing the opposite operation from both sides. For example, let"s do 5x=25. Since there is multiplication, we can use division to isolate the variable. You would divide both sides by the coifeiccent to get x=5.

Step-by-step explanation:
The system of equations needed to solve the given equations is . Thus, the correct graph is the top-right graph. Its plotted below.
How to find the system of equations needed to solve an equation?
An equation usually consists of equality of two mathematical expressions. Let it be
�
=
�
A=B . If we take them to be equal to third variable, then:
�

A=B=C type of equation is obtained.
We can then take it as system of two equations as:
�

=
�
A=C
B=C
Solution to this system will give us the solution to the considered equation
What is a solution to a system of equations?
For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs.
For the given case, we are given that:

Thus, the solutions are those two points that are intersections of those two curves.
