select three ratios and that are equivalent to 3:12
Final answer:
To find three ratios equivalent to 3:12, we simplify the ratio to 1:4 and then scale it up. The three equivalent ratios are 2:8, 3:12 (the original ratio), and 4:16.
Explanation:
To find three ratios equivalent to the ratio 3:12, we need to simplify or scale the given ratio up or down. Given that 3:12 simplifies to 1:4 (by dividing both numbers by their greatest common divisor, which is 3), any multiple of this simplified ratio will also be equivalent to 3:12.
By multiplying both terms of the ratio 1:4 by 2, we get the equivalent ratio 2:8.Multiplying both terms by 3 gives us another equivalent ratio, 3:12, which is our original ratio and shows that multiplying by a common factor yields an equivalent ratio.Lastly, multiplying both terms by 4 would give us the equivalent ratio 4:16.These three equivalent ratios show the concept of scaling a ratio up while maintaining the proportional relationship between the two quantities.

= 204
Therefore, Eliza read 204 in those 3 days.
Best of Luck!
Answer:
Part A: 204 pages
Step-by-step explanation:
Eliza reads of her book on Monday by [tex]\frac{r}{7}[/tex] pages, where r is the total number of pages in the book.
On Tuesday and Wednesday combined, she reads three times as much as she reads on Monday i.e. [tex]\frac{r}{7} * 3 = \frac{3r}{7}[/tex] pages.
So, combining Monday, Tuesday and Wednesday she reads [tex]( \frac{r}{7} + \frac{3r}{7} ) = \frac{4r}{7}[/tex] number of pages.
Part A: If Eliza's book has a total of 357 pages then combining Monday, Tuesday and Wednesday she reads [tex]\frac{4*357}{7} = 204[/tex] pages.

What number goes in the cell in row y, below 4?
Answer:
10.
Step-by-step explanation:
The formula for this table is y=x+6. plug in 4 and you get 10
Answer:
10
Step-by-step explanation:
Don't just think: 6,7,8,9, oh it must be 10.
When x is 0, y is 6. That means no matter what 6 is added to x. So if we look at when x is 2, y = 8. Lets subtract the 6 from the 8 and we get 2. So the x is not multiplied by anything.
The equation is y = x+6.
4+6=10

A student solved this problem by working backward.
Jared has some flowers. He has 6 more red flowers than yellow flowers. He has twice as many orange flowers as red flowers. He has 4 yellow flowers. How many flowers does Jared have altogether?
Student's solution:
Jared has 4 yellow flowers.
He has 6 more red than yellow flowers (4 + 6 = 10).
He has twice as many orange flowers as red flowers (10 × 2 = 20).
So Jared has 4 + 10 + 20 = 34 flowers.
Use a similar strategy to solve this problem.
Kathleen has some balloons. She has 7 more silver balloons than gold balloons. She has 3 times as many bronze balloons as silver balloons. She has 5 gold balloons.
How many balloons does Kathleen have altogether
Kathleen has 5 gold balloons, 12 silver balloons, and 36 bronze balloons. By adding the number of each type, she has a total of 53 balloons.
To determine how many balloons Kathleen has altogether, we can work backward just like the student did in the original problem. Here are the steps:
Kathleen has 5 gold balloons.She has 7 more silver balloons than gold balloons, so she has 5 + 7 = 12 silver balloons.She has 3 times as many bronze balloons as silver balloons, so she has 12 × 3 = 36 bronze balloons.Adding them all together: 5 gold + 12 silver + 36 bronze = 53 balloons.Hence, Kathleen has a total of 53 balloons.

Alliance Cannery received an order for 384 cans of food. The order can be made up of a combination of cans of fruit, which are processed at a rate of 24 cans per minute, and cans of vegetables, which are processed at a rate of 64 cans per minute.
x = number of minutes for fruit cans
y = number of minutes for vegetable cans
Which of the linear equations expresses the situation?
3x + 8y = 384
24x + 64y = 384
64x + 24y = 384
24x + 64y + 384 = 0
Answer:
24x + 64y = 384
The linear equation that expresses the situation is 24x + 64y = 384. This equation represents the number of cans of fruit (x) and cans of vegetables (y) processed at different rates. We can check the equation by plugging in values of x and y.
The linear equation that expresses the situation is 24x + 64y = 384. This equation represents the number of cans of fruit (x) processed at a rate of 24 cans per minute and the number of cans of vegetables (y) processed at a rate of 64 cans per minute. The left side of the equation represents the total number of cans processed, and the right side represents the total number of cans in the order, which is 384. We can check this equation by plugging in the values of x and y to ensure that it satisfies the condition of the order. For example, if we plug in x = 4 and y = 3, we get 24(4) + 64(3) = 384, which is true.

Hello:) For partial fractions, is
Quotient = remainder / diviser
a proper fraction?
Answer:
You can represent most things with a partial fraction, anything in the form:
[tex]\frac{f(x)}{(x+\alpha )(x-\beta )}=\frac{A}{(x+\alpha )}+\frac{B}{(x- \beta )}[/tex]
Notice how the roots of the equation from the denominator on the left hand side are used to form the denominations of fractions on the right hand side.
We can now multiply both sides by the denominator on the left hand side.
[tex]f(x)=A(x-\beta )+B(x+ \alpha )[/tex]
We can now setup 2 simultaneous equations by substituting [tex]x[/tex] for your values of [tex]-(- \beta )[/tex] and [tex]-\alpha[/tex] to make [tex]A[/tex] or [tex]B[/tex] 0, allowing you to find the other [tex]A[/tex] or [tex]B[/tex] value.
[tex]f(-\alpha ) = A(-\alpha - \beta) + 0\\f(\beta ) = 0 + B(\beta + \alpha )[/tex]
A construction crew built 1/3 miles of road in 1/6 days
What is the unit rate in miles per day?
Write your answer in the simplest form.
Answer:
2 miles per day
Step-by-step explanation:
The length of the road built is 1/3 miles, so let's call L = 1/3
The time spent to build this length is 1/6 days, so let's call D = 1/6
To find the unit rate in miles per day, that is, the speed that this length of the road was built, we just need to divide L by D (speed is distance over time). Let's call the speed S:
S = D/T
S = (1/3) / (1/6)
S = (1/3) * 6
S = 2 miles per day
The unit rate, which is the rate of distance built per day, is 2 miles per day. Calculated by dividing the total distance by the total time, multiplying 1/3 by the reciprocal of 1/6.
Explanation:This question involves the concept of unit rates. A unit rate tells us how one quantity relates to one unit of another quantity. In this case, we are asked to find the number of miles of road that can be built in one day (the unit rate).
To find the unit rate, we need to divide the total distance (1/3 miles) by the total time (1/6 days). When we divide fractions, we multiply the first fraction by the reciprocal of the second.
So, the calculation should be (1/3) ÷ (1/6) = (1/3) * (6/1) = 2.
So, the construction crew can build 2 miles of road in one day.

The equation y = 200(1.06)X models an exponential function. Determine if the
function is growth or decay and find the growth or decay rate.
Given:
The given function is
[tex]y = 200(1.06)^x[/tex]
To find whether the function is growth or decay and the growth of decay.
Formula:
The function [tex]a(1+r )^x[/tex] is said to be an exponential growth, if the value of a > 0 and r > 0
Again, the function [tex]a(1-r )^x[/tex] is said to be an exponential decay, if the value of a > 0 and 0 < r < 1.
Now,
[tex]y = 200(1.06)^x[/tex]
[tex]y = 200(1+0.06)^x[/tex]
Thus, the value of a > 0 and r > 0, then the given function is an exponential growth function.
Therefore,
The given function is an exponential growth function.

A toy store purchases small rubber balls that come in different colors in bulk from a wholesaler. The manager randomly filled the vending machine in the store with some of these balls. The machine has 30 yellow balls, 45 blue balls, and 75 pink balls. Suppose the store purchases a shipment of 2,000 rubber balls. How many balls of each color should be expected in the shipment?
Answer:
400 yellow 600 blue 1000 pink
Step-by-step explanation:
30 yellow balls, 45 blue balls, and 75 pink balls
initial sample = ratio of 2:3:5
Shipment 2000 = 2:3:5 = 400 yellow 600 blue 1000 pink
2+3 + 5 = 10 1) We add up the ratio
2000/10 = 200 2)We apply the ratio total to shipment total
and divide.
2 x 200 = 400 3)We multiply by 200
3 x 200 =600
5 x 200 = 1000
Simple as that.
Answer:
The collection of balls in the vending machine is a random sample of 150 balls. The percentage of balls of each color in the vending machine can be used as a model for the company’s shipment purchases:
P(yellow) =30/150 = 20%
P(blue) = 45/150= 30%
P(pink) =75/150 = 50%
If the store purchases 2,000 rubber balls, then about 2,000(0.2) = 400 should be yellow, 2,000(0.3) = 600 should be blue, and 2,000(0.50) = 1,000 should be pink.

What is the sum of the numbers in a data set divided by the total number of values in the data set?
A) Mean
B) Center of data
C) Range
D) Median
E) Outlier
Answer:
A) Mean
Step-by-step explanation:
The mean of a data set is one of the ways to calculate the center of tendency, center of data, or the "average".
Example of a set of data: 4, 2, 1, 6
Mean = sum of data / number of data
= (4 + 2 + 1 + 6) / 4
= 13 / 4
= 3.25
Other incorrect answers:
Range - this shows the difference between highest and lowest values in a data set.
Using our example:
highest = 6; lowest = 1
Range = highest - lowest
= 6 - 1
= 5
Median - this shows the "middle" of data if you lined them up from least to greatest, and found the number in the middle.
Using our example:
4, 2, 1, 6
1, 2, 4, 6 Reorder from least to greatest
1, 2, 4, 6 Focus on the middle
(2 + 4)/2 = 3 Find the mean of the two middle numbers
Median = 3
Outlier - this names a piece of data that is far off from what the rest of the numbers are
In our example, we have no outliers.
However, if the data was 4, 2, 1, 6, 20
Then the outlier would be 20.
