The value of q in the given equation is 0.

This is a problem from an algebraic equation, we can solve this problem by following a few steps.

The given equation is,

8(q-2) = 44+5(2q-12)

Let's simplify the equation.

8(q-2) = 44+5(2q-12)

Or, 8q- 16= 44+ 10q- 60

Now, we have to organize the equation.

8q- 10q= 44- 60+ 16

Or, -2q = 0

Or, q = 0/2        ( dividing both side by 2 )

Or, q = 0

The size of the tank would be suggested to hold 40 small fish is 48 gallons. (Solved using ratios)

What is a ratio?

A ratio in mathematics illustrates how many times one number contains another. For example, if a dish of fruit contains seven apples and six lemons, the apple-to-lemon ratio is seven to six. Similarly, the proportion of lemons to oranges is 6:7, while the proportion of oranges to overall fruit is 8:14. (or 4:7). A ratio can be defined by providing both constituent integers, which are written as "a to b" or "a:b," or by providing only the value of their quotient a/b. Equal quotients result in equal ratios. A and B are frequently referred to as ratio words, with A being the antecedent and B being the consequent.

This can be solved using ratios

size of tank = 40x6/5 = 48 gallon

Answer:

Step-by-step explanation:

Answer:

6.75m^2

Step-by-step explanation:

The shape is made up of a trapezoid on top and a rectangle on the bottom.

The rectangle's area is easier, so first:

Area_rectangle

= length × width

= 2.5 × .5

= 1.25 m^2

For area of a trapezoid, you need three measures: both bases and the height.

One base is 3m. The other base is the top side of the rectangle, so it is 2.5m.

The height is

2.5 - .5

because the height of the trapezoid is not including the rectangle, so take away .5

Trapezoid's height is 2.5 - .5 is 2.

Area_trapezoid

= 1/2 (base+base)height

= 1/2 (3+2.5)2

=5.5

Area_total

= Trapezoid+rectangle

= 5.5 + 1.25

=6.75m^2

The total area is 6.75square meters.

Answer:

Area = 6.75 meter square.

2-cup carton of milk = $0.56

2-quart carton of milk for $3.76​

i) 2-cup carton of milk = $0.56

1 cup =

Here, 1 cup carton of milk is $0.28

ii) 2-quart carton of milk = $3.76​

Given that 1 quart = 4 cups

2 quart = 4 * 2 = 8 cups

Thus

1 cup =

Here, a cup carton of milk is $0.47

$0.28 is less than $0.47, therefore the better buy would be 2-cup carton of milk for $0.56.

Therefore, the best buy would be 2-cup carton of milk for $0.56, because it is cheaper.

The phrase "six more than nine times n is twenty" as an equation will be;  (6+9)n=20

An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

The phrase "six more than nine times n is twenty" as an equation will be;

Since we are multiplying n by the addition of 6 and 9, we put 6 and 9 in parenthesis with the n on the outside which is equal to 20.

Then 6 + 9 goes inside the parenthesis.

Therefore, it will be;

The correct answer is The complete price (minus returns) is due within 30 days, or a 2 percent discount for payments made within 10 days.

2. Net Sales are Going Up.

Explanation:

1. The breakdown of a company's sales discounts with terms 2/10, n/30 is as follows:

The % discount is represented by 2,

You must pay the business within 10 days to be eligible for the discount.

If you were unable to pay the corporation within the first 10 days, you would have had n/30 days to do so. You are not eligible for the discount if you pay during this time frame after the first 10 days.

Consequently, the parameters of the sales discount mentioned above are a 2 percent discount for payment within 10 days, or the full amount (less returns) due within 30 days.

2. As goods are returned and risk must be managed, sales returns and sales allowances have the impact of lowering the net sales total. Therefore, if they decrease, net sales increase.

A decrease in the credit card company's discount also causes a rise in sales because it increases the amount made per sale or transaction and decreases the amount the company must provide in discounts.

The greatest number of bags that can be filled using all the candy is 9.

The greatest number of bags that can be filled using all the candy can be determined by calculating the greatest common factor (GCF).

The greatest common factor of two or more numbers is a term used in mathematics that can be described as the greatest number among all the common factors of these numbers. If x and y are two numbers, GCF is the largest number that divides both x and y without leaving any remainder.

As there are 36 chocolate bars and 81 caramel bars, therefore we determine the GCF of 36 and 81;

The common factors of 36 and 81 are found to be: 1, 3 and 9

Hence the greatest common factor (GCF) out of these is 9.
