The required value of y is 2645 / 77 when x = 77.
Step-by-step explanation:
1. Let's check the information given to answer:
if y varies inversely as x, and y = 23 when x = 115. Find y when x=77
2. What is y when x = 77?
As the statement "y varies inversely as x" translates into y = k/x
If we let y = 23 and x = 115, the constant of variation becomes
23 = k ÷ 115
k = 23 × 115
k = 2645
Thus the specification equation is y = 2645 ÷ x . Now, letting x = 77, we obtain
y = 2645 ÷ x
y = 2645 ÷ 77
<u>So, The required value of y = 2645 / 77 when x = 77</u>

Answer:
-2 < AC < 8
Step-by-step explanation:
The last side has to be less than the sum of the other 2 sides, or less than 8. The only answer choice with this is the 3rd one.
Answer:
Let the width of the garden =x meter
Then length=(x+4) meter
Half perimeter =36 m
So perimeter of garden =(2×36)=72 meters
According to the question
⇒2(l+b)=72
⇒2(x+x+4)=72
⇒2x+2x+4=74⇒4x=64⇒x=16 meters
Hence,the width of the garden =16 meters
The length of the garden =(16+4)=20 meters
I hate parabolas. i can't remember the equation. sorry.
The value of the game will be $ 0.08. Then the correct option is B.
<h3>What is probability?</h3>
Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
A game is played by rolling a fair six-sided die once.
If the die lands on a 1 the player win $8 otherwise the player loses $1.50.
Then the value of the game will be
The probability of success will be
p = 1/6
The probability of failure will be
p = 5/6
Then the value of the game will be
Value of game = 8p - 1.5q
Value of game = 8 x 1/6 - 1.5 x 5/6
Value of game = 1.3333 - 1.25
Value of game = 0.08333
Value of game ≅ $ 0.08
