Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.
Answers
We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:
0.80D = 0.24L
We are also given that the mass of the lion is 105 kg more than the mass of the dog:
L = D + 105
We can use these two equations to find the values of D and L.
Substituting the value of L from the second equation into the first equation:
0.80D = 0.24(D + 105)
Now, let's solve for D:
0.80D = 0.24D + 0.24(105)
0.80D - 0.24D = 25.2
0.56D = 25.2
D = 25.2 / 0.56
D ≈ 45
Now that we have the value of D, we can find the value of L by substituting it back into the second equation:
L = 45 + 105
L = 150
Therefore, the total mass of the dog and the lion is:
D + L = 45 + 150 = 195 kg
So, the total mass of the dog and the lion is 195 kg.

On a coordinate plane, a triangle has points R (negative 1, 3), S (3, negative 2), and T (1, negative 4). Which reflection will produce an image of ΔRST with a vertex at (2, –3)? a reflection of ΔRST across the x-axis a reflection of ΔRST across the y-axis a reflection of ΔRST across the line y = x a reflection of ΔRST across the line y = –x
Answers
Answer:
a reflection of ΔRST across the line y = –x
Step-by-step explanation:
A reflection across the line y = –x transforms point (x, y) into (-y, -x)
After reflecting ΔRST across the line y = –x we get:
R (-1, 3) -> (-3, 1)
S (3,-2) -> (2, -3)
T (1, -4) -> (4, -1)
where S is at the desired vertex

Is -4/5 rational or irrational
Answers
Answer: Rational
Step-by-step explanation:
The number -0.8 is rational if it is an integer or decimal
A rational number is a number that can be represented as a/b where a and b are integers and b is not equal to 0.
Since -0.8 is an integer or decimal from above, -0.8 is also a rational
An irrational number is a number that cannot be expressed as a ratio between two integers and is not an imaginary number.
Answer:
It is a rational number
Step-by-step explanation:
An irrational is a number that repeats in a sequence or not.
It is a number that never stops. ex. pi, 2/3.
-4 divided by 5 is -0.8 which is a rational number

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get

Describe a simulation that you can use to model this situation. The simulation should be different from the one in part C.
Space used (includes formatting): 0 / 15000
Answers
Answer: all awnsers below
Step-by-step explanation:
1. Define the number of coin flips to be simulated (e.g., 1,000 flips).
2. Initialize two counters, `headsCount` and `tailsCount`, to keep track of the number of heads and tails, respectively.
3. Repeat the following steps for the specified number of coin flips:
a. Generate a random number between 0 and 1.
b. If the generated number is less than 0.5, increment `headsCount` by 1. Otherwise, increment `tailsCount` by 1.
4. Calculate the experimental probabilities by dividing `headsCount` and `tailsCount` by the total number of coin flips.
5. Compare the experimental probabilities with the theoretical probability (0.5 for a fair coin).
6. Repeat the simulation multiple times (e.g., 100 times) and calculate the average difference between the experimental and theoretical probabilities to evaluate the simulation's accuracy.
By running this simulation multiple times, we can assess how closely the experimental probabilities match the theoretical probability on average. This simulation provides a different approach compared to the previous one and can be used to model the situation with more flexibility and accuracy.

3/4 is .75 gallon. To find how many pumpkins he can paint, divide .75÷ .03 = 25 pumpkins.
Step-by-step explanation:
To convert fractions to decimals, divide the numerator by the denominator. 7/8 = .875
To convert a decimal to a fraction, use the digits as the numerator and make the denominator a power of 10 with one place more than the numerator. Then reduce or simply. Examples:

A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
