Answer:
The two equations are:
x+y=60
x=3y, where
x is Tripp's weight
y is Rico's weight
Step-by-step explanation:
Given that the information says that together the two dogs weigh 60 pounds, you can write the first equation that would indicate that the result of adding up the weight of the dogs is equal to 60, which can be expressed as:
x+y=60, where
x is Tripp's weight
y is Rico's weight
Also, the statement indicates that Tripp weighs 3 times more than Rico and you can expressed this with the following equation that indicates that Tripp's weight is equal to multiplying Rico's weight for 3:
x=3y
According to this, the two equations are:
x+y=60
x=3y, where
x is Tripp's weight
y is Rico's weight

What is an equation of the line that passes through the points of (0,-4) and (-4,6)
Answer:
y = -5/2x - 4
Step-by-step explanation:
(0,-4) and (-4,6)
Slope:
m=(y2-y1)/(x2-x1)
m=(6+4)/(-4-0)
m=10/-4
m= -5/2
Slope-intercept:
y - y1 = m(x - x1)
y + 4 = -5/2(x - 0)
y + 4 = -5/2x
y = -5/2x - 4
Ellie purchased 7 shirts that were originally priced at $15.50

What was the total cost of the 7 shirts after she received both her discounts? Write your
answer to the Hundredths Place, DO NOT USE A $ Sign)
The total cost for 7 shirts was type your answer
dollars.
Answer:
10.85
Step-by-step explanation:
Answer:
11.16
Step-by-step explanation:
20% of $15.50 is $3.10 and 15.50 - 3.10 is 12.40
10% of 12.40 is 1.24 12.40 - 1.24 = 11.16 meaning that the total cost was 11.16 at the end

Anne Kates house is 20c. She had just made a fresh cup of tea (100c). Five minutes after she made her mad scientist nephew came in,stuck a thermometer in the cup and announced that the tea was now only 70c Write the possible equation with asymptotes
Answer:
The possible equation is; T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]
The horizontal asymptotes is Lim(t → ∞), T → 20°C
The vertical asymptote is Lim(t → 0) T → 100°C
Step-by-step explanation:
The given parameters are;
The temperature of the house = 20°C
The initial temperature of the tea = 100°C
The temperature of the tea after 5 minutes = 70°C
From Newton's law of cooling, is given as follows;
[tex]T(t) = T_s + (T_0 - T_s) \cdot e^{k \cdot t}[/tex]
[tex]\dfrac{dT}{dt} = -k(T - T_a)[/tex]
Where;
T(t) = The temperature after time, t =
[tex]T_s[/tex] =The room temperature = 20°C
T₀ = The initial temperature of the tea = 100°C
k = Constant
T(5) = 70°C, therefore, we have;
[tex]70 = 20 + (100 - 20) \cdot e^{k \cdot 5}[/tex]
50/80 = [tex]e^{k \cdot 5}[/tex]
5·k = ㏑(5/8)
k = ㏑(5/8)/5 ≈ -0.094
Therefore, the possible equation is given as follows;
T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]
The asymptotes are Lim(t → ∞), T → 20°C and Lim(t → 0) T → 100°C

What is an Absolute value function?An absolute value function is a function that gives positive value for a number or variable. It has a V shaped graph, it is also called as a modulus function.
The absolute function is y = | -x +7| +-4
The v shaped curve has a vertex and it can be determined by following method.
The value of the x coordinate is determined by equating the modulus to 0, the point at which the modulus is zero.
-x +7 = 0
Adding -7 to both sides.
-x = -7
x = 7
The value of y at this point is the y coordinate of the vertex.
y = 0 +4
y = 4
(x,y) = ( 7,4)

Steve is playing a carnival game. He wants to win a prize, but he thinks he has about a 20% chance of winning. He uses the expression 0.2t to calculate the number of games he will need to play in order to win a prize.
If he plays the game 12 times, about how many times can he expect to win?
Answer:50%
Step-by-step explanation:
Steve's expected times of winning in 12 trials is about 2 times.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
The winning chance of Steve is 20% or 0.2.
We know, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory.
Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.
Therefore, If he plays the game 12 times the number of times he is expected to win is,
= 12×0.2.
= 2.4 Or 2 times.
