Answer:
v = 10
Step-by-step explanation:
-10 - 6(2v-8) = -82
-10 - 12v + 48 = -82
-12v + 38 = -82
-12v = -120
v = 10
hope this helped, if you need a more in depth answer to how i did it just ask
Answer:
Hello! I hope I’m correct! :)
Step-by-step explanation:
The answer should be V = 10
First, Add 10 to both sides.
-6(2v-8) = -82+10
Next, Simplify
-6(2v-8) = -72
Than, divide both sides by -6
= -72/-6
{Note: two negatives makes a positive}
= 72/6
Simplify.
2v-8=12
Add (+) 8 to both of the sides.
2v= 12+8
Simplify 12+8 to...
2v = 20
Now, divide both sides by 2
V = 20/2
Since we have 20/2, we need to simplify (divide 20 & 2)
20 divided by 2 = 10
V = 10
Therefore the answer is v = 10Hope this helps! If you have any questions about these steps, feel free to ask! Have a nice day! :)

If a bird is flying 75 ft above the ocean's surface, and a shark is swimming at a depth of 30 ft, what is the distance between the bird and the shark?
Answer:
105 ft
Step-by-step explanation:
since the shark is swimming at a depth of 30 ft mean is -30 ft...
so the distance between the bird and the shark is

Find the inverse of f(x)= 2x+3/x-1
Answer:
[tex]\displaystyle f^{-1}(x)=\frac{3+x}{x-2}[/tex]
Step-by-step explanation:
We have the function:
[tex]\displaystyle f(x)=\frac{2x+3}{x-1}[/tex]
Find the inverse of f(x). First, we call y=f(x):
[tex]\displaystyle y=\frac{2x+3}{x-1}[/tex]
We have to solve for x. Multiply by x-1:
[tex]y(x-1)=2x+3[/tex]
Operate:
[tex]yx-y=2x+3[/tex]
Join all the x's to the left side and move the rest to the right side:
[tex]yx-2x=3+y[/tex]
Factor:
[tex]x(y-2)=3+y[/tex]
Solve for x:
[tex]\displaystyle x=\frac{3+y}{y-2}[/tex]
Interchange the variables:
[tex]\displaystyle y=\frac{3+x}{x-2}[/tex]
This is the inverse function:
[tex]\boxed{\displaystyle f^{-1}(x)=\frac{3+x}{x-2}}[/tex]

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that some college roommates want to make pancakes for their neighbors. They need 7 cups of flour but only have a 1/6 cup measuring cup.
The number of times the cup is to be used will be calculated by dividing the numbers below:-
Number = 7 / ( 1 / 6 )
Number = 7 x 6
Number = 42 times
Therefore, they have to fill the measuring cup by 42 times.

2P - 3 > P + 6
Thanks!
Answer:
P > 9
Also here is the inequality graphed.
Step-by-step explanation:
Start by subtracting P on both sides.
2P − 3 (−P ) > P + 6 (− P)
P − 3 > 6
Next you will need to add 3 to both sides.
P − 3 (+3) > 6 (+3)

A bicycle is traveling at 17 miles per hour.
How many feet will it cover in 60 seconds?
Round your answer to the nearest tenth of a foot.
Answer:
The bicycle will cover about 943.36 feet.
Step-by-step explanation:
1 mile = 5280 ft
5280 x 16 = 84480
84480 / 60 = 1408 ft per minute
40 seconds of 1 minute = .66 or .67 of a minute
1408 x .67 = 943.36

30. While making a dessert, Jane used
9/10 of a scoop of brown sugar as well
as 1/2 of a scoop of white sugar. How
much more brown sugar did Jane use?
Answer:
Jane used 2/5 of a scoop more of brown sugar than she did with white sugar.
Step-by-step explanation:
If you want to find how much more something is from something else, you subtract. So, subtract 9/10-1/2. If you want to subtract, they should both have the same denominator. So, 9/10-1/2 is the same as 9/10-5/10. 9/10-5/10 is equal to 4/10 which is simplified to 2/5.

The difference of two supplementary angles is 58 degrees. Find the measures of the angles.
Answer:
The measure of the angles are 61° and 119°
Step-by-step explanation:
Let the first angle = x°
let the second angle = y°
The sum of two supplementary angles = 180°
x° + y° = 180° ----- equation (1)
based on the given question; "the difference of two supplementary angles is 58 degrees."
x° - y° = 58° ------- equation (2)
from equation (2), x° = 58° + y°
Substitute the value of x into equation (1)
(58° + y°) + y° = 180°
58 + 2y = 180
2y = 180 -58
2y = 122
y = 122 / 2
y = 61°
The second angle is given by;
x° = 58° + y°
x = 58° + 61°
x = 119°
Thus, the measure of the angles are 61° and 119°

Consider the following game, played with three standard six-sided dice. If the player ends with all three dice showing the same number, she wins. The player starts by rolling all three dice. After this first roll, the player can select any one, two, or all of the three dice and re-roll them. After this second roll, the player can again select any of the three dice and re-roll them one final time. For the following questions, assume that the player used the following optimal strategy: if all three dice match, the player stops and winds; if two dice match, the player re-rolls the die that does not match; and if no dice match, the player re-rolls them all.
Requied:
a. Find the probability that all three dice show the same number on the first roll.
b. Find the probability that exactly two of the three dice show the same number after the first roll.
c. Find the probability that the player wins, conditioned on exactly two of the three dice showing the same number after the first roll.
Answer:
a
[tex]P(A) = \frac{1}{36}[/tex]
b
[tex]P(B) = \frac{15}{36}[/tex]
c
[tex]P(U) = \frac{11}{36}[/tex]
Step-by-step explanation:
From the question we are told that
The number of dice is [tex]n = 3[/tex]
Generally for all three dice to show the same number the second and the third dice must have the same outcome as the outcome of the first dice.
This means that the number of outcome the first die can have is 6 (6 sides), the number of outcome which the second and the third dice can have is 1 (they must match the first )
So the probability that all three dice show the same number on the first roll is mathematically represented as
[tex]P(A) = \frac{6}{6} * \frac{1}{6} * \frac{1}{6}[/tex]
=> [tex]P(A) = \frac{1}{36}[/tex]
Generally for two of the three dice show the same number after the first roll then the number of outcome for one of the dice would be is 6 , the number of outcome for another one must be 1(i.e it must match the first ) , the number of outcome for the remaining one must be 5 (i.e it can show any of the remaining 5 sides which the first and second dice are not showing )
Now the number of ways of selecting this 2 dice that show the same number from the 3 dice is mathematically represented as
[tex]N = ^3C_2[/tex]
Here C stands for combination
So
[tex]N = ^3C_2 = 6[/tex]
So the probability that exactly two of the three dice show the same number after the first roll is mathematically represented as
[tex]P(B) = N \frac{1}{6} * \frac{5}{6}[/tex]
=> [tex]P(B) = \frac{15}{36}[/tex]
Generally from the question we are told that if two dice match, the player re-rolls the die that does not match.
Now the probability that the die that did not match the first time will match the second time is
[tex]P(E ) = \frac{1}{6}[/tex]
Generally if that one die does not show the same number in the second round , the probability that it will match in the third round is
[tex]P(R) = \frac{5}{6} * \frac{1}{6} [/tex]
Generally the probability that he wins (i.e when all three are showing the same number ) and exactly two is showing the same number is mathematically represented as
[tex]P(K) = P(E)* P(B) + P(R)* P(B)[/tex]
=> [tex]P(K) = \frac{1}{6} * \frac{15}{36} + \frac{5}{6} * \frac{1}{6} * \frac{15}{36}[/tex]
=> [tex]P(K)= \frac{165}{1296}[/tex]
So the probability that the player wins, conditioned on exactly two of the three dice showing the same number after the first roll is mathematically represented as
[tex]P(U) = \frac{\frac{165}{1296}}{\frac{15}{36} }[/tex]
=> [tex]P(U) = \frac{11}{36}[/tex]

Complete question :
X: 20__25 ___30 ___35
f(x): 0.20 _0.20_0.25 _0.35
Probability that x = 30
Probaility that x less than or equal to 25
Probability that X is greater than 30
Answer:
Kindly check explanation
Step-by-step explanation:
To establish if it is a valid probability distribution :
The sum of the probabilities must be equal to 1:
Σf(x) = 0.20 + 0.20 + 0.25 + 0.35 = 1
Hence it is valid
Probability that x = 30
P(x = 30) = 0.25
Probability that x ≤ 25 :
P(x = 20) + p(x = 25)
P(x ≤ 25) = 0.20 + 0.20 = 0.40
Probability that x > 30
P(x > 30) = p(x = 35) = 0.35
