After school Rayah skateboards at a constant rate from her house to her friend's house 1.8 miles away. It takes her 12 minutes to get there. Which 2 variable equation represents this situation?
Answer:
Step-by-step explanation:
Given that:
Distance to friends's house = 1.8 miles
Time taken = 12 minutes
Since the rate is constant :
The rate Is related to distance and time :
The two variable equation which represents the equation is :
Speed = Distance / time
A new motorcycle has a value of $8000 every year is value decreased by $500 which function can be used to find why the value of motorcycle in X years?
The function for the value of the motorcycle after x years are;
y = 8000 - 500x
y = -500x + 8000
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have given that new motorcycle has a value of $8,000. Every year its value decreases by $500.
Now, we have y = amount of the motorcycle
x = number of years
The function for the value of the motorcycle after x years.
y = 8000 - 500x
y = -500x + 8000
Thus,
y = 8000 - 500x
y = -500x + 8000

a. x= 20
b. x = 30
c. x = 60
d. x = 120
Answer:
Step-by-step explanation:
∠5 + ∠4 = 180°
4x° + 2x° = 180°
6x° = 180°
x = 30
Which is an example of a quadratic function whose axis of symmetry is to the right of the y-axis?
A. y=-x2 - 2x + 1
Answer:
a.
Step-by-step explanation:
imagine a graph that you see, the x-axis has to be positive for it to be on the right side of the y-axis so the value of the y axis can be positive or negative and then you substitute for a positive number, in this case, into the x axis and then you would solve for every answer choice to see if it's right or not if it is accurate.
What does 1/4 equal for a fraction
Answer: 0.25 as a decimal
Answer:
0.25
Step-by-step explanation:
You can think of fractions as smaller increments of money.
2/4=0.5
3/4=0.75
Bob has a dollar bill. He uses 1/4 of it to buy a coupon.
Imagine this happening:
1$
Uses 1/4
So... Let's look at what I've given you.
2/4=0.5
3/4=0.75
Well, let's stretch some things a liiiiitle bit.
Bob has a dollar bill blah blah...
We get to 1/4.
Le's make that 2/4.
2/4 is 0.5
So... By stretching the truth
We can infer that
If we put 1/4 back
(Oh no now the word problem creators are mad at me ;) lol)
Anyways, we can infer that by putting 1/4 back
That since 3/4 is 0.75
Then what's connected to 0.5 and 0.75?
The answer, my friend,
Is 0.25

A water tank already contains 56 gallons of water in Baxter begins to fill it. water flows into the tank at a rate of 8 gallons per minute. write a linear equation to model this situation. Find the volume of the water in the sink 5 minutes after Baxter begins filling the tank.
Answer:
Equation: y = 8x + 56
After 5 minutes, the volume of the water was 96 gallons
Step-by-step explanation:
Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.
Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.
There are already 56 gallons of water in the tank, so b will be 56.
Plug in these values into the equation:
y = 8x + 56
So, the linear equation is y = 8x + 56
Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:
y = 8x + 56
y = 8(5) + 56
y = 40 + 56
y = 96
So, after 5 minutes, the volume of the water was 96 gallons

How many times 0.25 can be
subtracted from 5 ?
Answer:
once
Step-by-step explanation:
The solution of the subtraction operation is equal to 4.75 .
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS - Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We need to Subtract 0.25 subtracted from 5
We know that 0.25 x 20 = 5
so, the subtraction is;
5 - 0.25 = 4.75
The answer is 4.75 .

multiple choice pls help
Answer:
x = 28.9
Step-by-step explanation:
tan = [tex]\frac{opposite}{adjacent}[/tex]
⇒ tan 48 = [tex]\frac{26}{x}[/tex]
(tan of 48 is 1.11)
⇒ 1.11 = [tex]\frac{26}{x}[/tex]
multiply 26 on both sides
⇒ 1.11 x 26 = [tex]\frac{26}{x}[/tex] x 26
⇒ 28.86 = x
round to the nearest tenth
⇒ 28.86 = 28.9
