Answer:
The scale in the ratio given considers the case that there are 9 sweets (2 + 3 + 4), however, to answer our question, we need to scale up the ratio, so that we can work out the share when we have 36 sweets
Step-by-step explanation:
Ratios are a way of displaying the proportional split of a value and they are very similar to fractions. In the example above, we see that for every 2 sweets Amy has, Beth gets 3 and, Colin will get 4. Like fractions, this proportion will stay the same regardless of the scale of the ratio. The scale in the ratio given considers the case that there are 9 sweets (2 + 3 + 4), however, to answer our question, we need to scale up the ratio, so that we can work out the share when we have 36 sweets. So, what scale factor do we need to get it from a total of 9 sweets to a sum of 36 sweets? We know that 9 multiplied by 4 gives us 36, therefore, we can use a scale factor of 4. Remember how whatever is done to the denominator of a fraction has to be done to the numerator? Ratios like to behave the same way, so now that we have scaled up the sum of the ratio, we need to scale up the individual values by 4 – (2x4) : 3x4 : 4x4. Once we work it out we get the new ratio 8:12:16. You can check if you’re right by adding up the new values and you will see that 8 + 12 + 16 = 36, which is the value that the 9 was initially scaled up to. So we now know that when sharing the 36 sweets, Amy will get 8 sweets, Beth will get 12 sweets and Colin will get 16.

1. Bill decided to buy six books on history instead
of four books on politics. It follows, then, that
the opportunity cost of each history book was ______
books on politics.
Answer: 2/3 books on politics
Step-by-step explanation:
The opportunity cost of something is the next best alternative that you would have taken if you did not instead go for the option that you took.
Opportunity cost here is the number of books on politics that Bill had to give up to get a single book on history.
= Number of politics books / Number of history books
= 4 / 6
= 2/3 books on politics
Bill gave up 2/3 books on politics to get a single history book.
You often go to school by bus. You have two bus systems you could take. City Bus offers a monthly pass that costs $15 and then you pay $1 per ride. Campus Transport simply charges $2.50 per ride and does not require a monthly pass. After how many rides will the total costs of the two options be the same? Write a system of equations in order to solve this problem.
Answer:
For City Bus you will need to ride 10 times for 2 months, and for Campus Transport you need to ride 16 times.
Step-by-step explanation:
$2.50 x 2 = $5.00 so you know that the number of rides needs to even in order to have a whole number. This is because there is no way the City Bus cost will ever have cents.
$2.50 x 16 = $40.00
$15 x 2 = $30
$1 x 10 = $10
$30 + $10 = $40
So (15 x 2) + (10 x 1) = 16 x 2.50

Hi! Could you help me me out and solve these two problems? "eight less than the product of seven and xxx", and "the sum of six and the product of three and d". Thank you!
Given:
The given statement are:
a. Eight less than the product of seven and x.
b. The sum of six and the product of three and d.
To find:
The expression for the given statements.
Solution:
a.
Product of 7 and x is 7×x = 7x.
Eight less than the product of seven and x is 7x - 8.
Therefore, the required expression for the statement "Eight less than the product of seven and x" is 7x-8.
b.
Product of 3 and d is 3×d = 3d.
The sum of six and the product of three and d is 6+3d.
Therefore, the required expression for the statement "The sum of six and the product of three and d" is 6+3d.

What is (15x + 7) + (-11x – 2)?
Answer:
4x + 5
Step-by-step explanation:
After solving the given equation, the value obtained for x will be equal to -5/4.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given expression in the question,
(15x + 7) + (-11x - 2)
15x + 7 -11x - 2
4x + 5
Now, solve it for x,
4x = -5
x = -5/4

Anna opened a savings account and deposited $300.00 as principal. The account earns 1%
interest, compounded annually. What is the balance after 2 years?
Answer:
$6
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1%/100 = 0.01 per year,
then, solving our equation
I = 300 × 0.01 × 2 = 6
I = $ 6.00
The simple interest accumulated
on a principal of $ 300.00
at a rate of 1% per year
for 2 years is $ 6.00.
