Answer:
The ratio of 2 batches of recipe is 6:2. Which is equivalent to 3:1 because if we multiply the ratio with same number it would give us equivalent ratio.
Step-by-step explanation:
When mix 3 teaspoon of Yellow water with 1 teaspoon of red water, we get ratio as 3:1
If we use 2 batches of recipe, the ratio is multiplied twice.
That's ratio of yellow water to red water is 3*2 :1*2 , which gives 6:2
But, if we simplify the ratio, by dividing both by common factor, we would get 3:1
That's [tex]\frac{6}{2} :\frac{2}{2}[/tex] simplified to 3:1

PLEASE HELP I really need it!!! Steve deposited 2,500$ to the bank. The account has an annual simple interest rate of 4%. After 3 years how much simple interest will Steve Earn? Please Help ASAP
Answer:
$300
Step-by-step explanation:
You want to calculate the interest on $2500 at 4% interest per year after 3 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $2500.00.
r is the interest rate, 4% per year, or in decimal form, 4/100=0.04.
t is the time involved, 3....year(s) time periods.
So, t is 3....year time periods.
To find the simple interest, we multiply 2500 × 0.04 × 3 to get that:
The interest is: $300.00
Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),
or 2500.00 + 300.00 = 2800.00

240 is 75% of what number?
Answer:
320Step-by-step explanation:
Let the unknown number be x
[tex]75 \% \times x = 240 \\ \frac{75x}{100} = 240[/tex]
Cross Multiply
[tex]75x \times 1 = 100 \times 240 \\ 75x = 24000[/tex]
Divide both sides of the equation by 75
[tex] \frac{75x}{75} = \frac{24000}{75} [/tex]
Simplify
[tex]x = 320[/tex]
Answer:
320
Step-by-step explanation:
you would do [tex]\frac{75}{100}[/tex]*x=240
then you would multiply both sides by 100 and then divide both sides by 75 which woud give you x=240*[tex]\frac{100}{75}[/tex]
which would give you [tex]\frac{24000}{75}[/tex]=x
which then simplifies down to 320

Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing, what would the inequality be?
The inequality is 0.75x greater than or equal to y
Step-by-step explanation:
Given : Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing.
To find : Which inequality represents this situation?
Solution : He plays trumpet for a minimum of 45 minutes
If x is the number of days that Lionel practices then he practices for at least
hours
y is the total number of hours he spends practicing
So, the inequality form is:
i.e, 0.75x is greater than y.
A car is driving down from the top of a Colorado mountain. The elevation is 13,500 feet. Every minute of driving, the car's elevation decreases by 150 feet. Let x be the time in minutes that the car has been driving down the mountain , E(x) = -150x+13,500. Evaluate E(5), and explain the meaning of the answer in terms of the car.
Answer:
Step-by-step explanation:
Given the rate at which the car elevation decreases expressed by the function
E(x) = -150x+13,500 where x is in minutes.
To evaluate E(5), we will substitute the variable x = 5 into the function as shown;
E(5) = -150(5)+13,500.
E(5) = -750+13,500.
E(5) = 13500-750
E(5) = 12750
This means that after 5minutes, the car elevation has decreased by 12,750feet

Gepetto, a puppet maker, can produce 15 new puppets per week. He already has 25 completely finished puppets in storage. We want to write an equation to model the relationship between the number of puppets available for sale and the number of weeks. a) What is the slope of your model? (Hint: you are looking for a rate!) b) What is the y-intercept of your model? (Hint: this is also sometimes called the “starting value.”) c) Write an equation in slope-intercept form expressing the relationship between the number of puppets available for sale and the number of weeks. Make sure to define your variables! d) Use your equation to predict how many puppets would be available for sale after seven weeks. e) Use your equation to determine how many weeks it would take Gepetto to fulfill an order for 220 puppets.
Answer:
a) 15
b) 25
c) p = 15w + 25, where p is puppets and w is weeks
Step-by-step explanation:
a) Gepetto makes 15 puppets a week, so as the weeks increase by 1, puppets increases by 15, making the slope 15
b) Gepetto started out with 25 puppets. This means that when x = 0 (0 weeks), there will be 25 puppets already
c) The slope and y-intercept were incorporated into an equation in slope-intercept form.

When do you use a Vertex Form y=a(x – h)2 + k ? What information do you get from a Vertex Form?
Please tell me
y = a(x - h)² + k is the vertex form of an equation of a parabola with vertex (h,k)
We get the coordinates of the vertex of parabola from that form: (h, k)
We also know if the parabola goes up or down: a>0 or a<0
We can tell how many roots has the equation:
(a>0 and q>0) or (a<0 and q<0) ⇒ no roots
a≠0 and q=0 ⇒ one root: x₀=p
(a>0 and q<0) or (a<0 and q>0) ⇒ two roots
We can also determine the roots (if they exist):
a(x - h)² + k = 0
a(x - h)² = - k
(x - h)² = - k/a
x - h = √[-k/a] ∨ x - h = - √[-k/a]
x = √[-k/a] + h ∨ x = - √[-k/a] + h
Usually you use this form to find the equation of parabola when you have got given the vertex and some other point from that parabola.

Answer:
f(3) = -9
Step-by-step explanation:
Given that,
→ f(x) = -7x + 12
Then the value of f(3) will be,
→ f(3) = -7(3) + 12
→ f(3) = -21 + 12
→ [ f(3) = -9 ]
Hence, the value is -9.
Which graph represents a line with a slope of -2/3 and a y-intercept equal to that of the line y = 2/3x – 2?
A coordinate plane with a line starting at (negative 2, negative 4), passing through (0, negative 2) and (2, 1).
A coordinate plane with a line passing through (negative 3, 0) and (0, 2).
A coordinate plane with a line passing through (0, 2) and (2, negative 1).
A coordinate plane with a line passing through (negative 3, 0) and (0, negative 2).
Answer:
graph 1
Step-by-step explanation:
Graph using table of values
x y
2 -2/3
1 -4/3
0 -2
they are all on that graph
The graph represents a line with a slope of -2/3 and a y-intercept equal to that of the line y = 2/3x – 2 is A coordinate plane with a line passing through (negative 3, 0) and (0, negative 2).
What is slope?The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx.
What are intercepts?Using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.
According to the question
Represents a line with a slope of -2/3
i.e ,
m = -2/3
y-intercept equal to that of the line
y = [tex]\frac{2}{3}x-2[/tex]
i.e ,
at y-intercept , x = 0
y = -2
Now, Putting value in standard form of line
y = mx + c
-2 = 0 + c
c = -2
now , substituting the values of m and c in standard form of line
y = mx + c
y = [tex]\frac{-2}{3}x-2[/tex] --------- (equation of graph )
Now ,
x y
0 -2
3/2 1
3 0
Only option 4 have these points
Hence, The graph represents a line with a slope of -2/3 and a y-intercept equal to that of the line y = 2/3x – 2 is A coordinate plane with a line passing through (negative 3, 0) and (0, negative 2).

Action Video rents DVDs and VHS movies to its customers. The cost to rent d, DVD movies, is $3.50 each and the cost to rent r, VHS movies, is $2.50 each. Which of these represents the possible number of DVDs that could be rented for no more than $20?
Answer and explanation:
To determine number if DVDs that can be bought for $20, we simply check price per DVD then calculate how many $20 can buy
Number of DVDs that can be rented for no more than $20
=$20 divided by cost of each DVD $3.50
=20/3.50
=5.714
=5 DVDs
We round down because 0.714 DVD does not qualify as one DVD

B. 100 times
C. One-tenth
D. One hundredth
Answer:
A. 10 times
Step-by-step explanation:
Answer:
A. Ten times.
Step-by-step explanation:
If it was one place to the right, it would have been one-tenth, so that's gone. If it was moved twice in place of either direction, it would be hundredths, so those are also eliminated. So, It's 10 times.
