After finding the fish you would like to take home to cook, you discover it cost $2 to wrap the fish and $4.50 per pound. Another vendor is selling another fish for a flat rate of $5 per pound. Set up an equation to determine how many pounds of fish would result in the same cost. Then, solve the equation.
Answers
Equation: 2 + 4.50x = 5x
Step by step
We know one vendor charges $2 + $4.50/#
We know one vendor charges $5/#
X = unknown # pound
Our equation will be separated by = sign because we are looking for when the price will equal
2 + 4.50x = 5x
Subtract 4.50x from both sides to isolate the variable
2 = .50x
Divide both sides by .50 to solve for x
X = 4 # fish
Substitute your x value (4) for x in your equation
4.50x4 + 2 = 5x4

Inequality expressionsInequalities are expressions that are not equated by an equal sign. Given the expression below:
3(8 – 4x) < 6(x – 5)
Expand to have:
3(8) - 3(4x) < 6x - 6(5)
24 - 12x < 6x - 30
Collect like terms
-12x - 6x < -30 - 24
-18x < -54
Divide both sides by -18
-18x/-18 < -54/-18
x < 54/18

Both statements can be included in the exact numbers category.
Maple provides two kinds of numbers: exact and inexact. If you do arithmetic with exact numbers (and they aren't too large) the answer that you get back is exactly right. If you do arithmetic with inexact numbers (and they aren't too large or too small) the answer may have a small amount of roundoff error. Although we'll treat this distinction at length in future lessons, it is convenient to take a preliminary look right now.

Acme widgets had an order to process 250 widgets. The first unit required 200 minutes to assemble. Before starting, the company estimated the amount of time it would require to assemble all 250 widgets if they learned at an 85% rate. After assembling all 250 widgets, acme realized they had learned at an 80% rate. How much time less than their estimate did acme take? you should be able to compute the answer within plus or minus 2 hours.
Answers
91.2 hours less was taken to assemble the parts of the widgets by estimation.
Firstly, we will find out the range:
Using the cumulative unit table to determine the range, we get that-
Range = 88.83 - 61.47
Range = 27.36
Secondly, we will calculate the minutes requires to assemble the widgets.
Number of minutes = 27.36 × 200 minutes
Number of minutes = 5472minutes
Now, we have to calculate how much time less than their estimate did acme take:
Time = 5472 / 60
Time = 91.2
Therefore, we get that, 91.2 hours less was taken to assemble the parts of the widgets by estimation.

Find the measure of the longest angle
Answers
The largest angle of the given triangle is 105 degrees. If its measure of other two angles are (6x +17) degrees and (5x + 14) degrees.
According to the given question.
We have, the measure of the angles of a triangle are 105 degrees,
(6x +17) degrees, (5x + 14) degrees.
As we know that the sum of the angles of a triangle is always 180 degrees.
Therefore, we can say that
105 + (6x +17) + (5x + 14) = 180
⇒ 105 + 6x + 17 + 5x + 14 = 180
⇒ 136 + 11x = 180 (adding the like terms)
⇒ 11x = 180 -136
⇒ 11x = 44
⇒ x = 44/11
⇒ x = 4 degrees.
So, (6x +17) degrees = 6(4) + 17 = 24 + 17 = 41 degrees
and, (5x + 14) degrees = 5(4) + 14 = 20 + 14 = 34 degrees
Hence, the largest angle of the given triangle is 105 degrees. If its measure of other two angles are (6x +17) degrees and (5x + 14) degrees.

f) cents
g) Cents 102.9 convert to Dollars 1.029
h) Cents 98.9 convert to Dollars 0.989
i) $56.60
j) $54.40
Step-by-step explanation:
e) is correct. The discount is 4¢ per litre
f) It should be cents, not dollars
g) Without a voucher, the cost of fuel is 102.9¢ = $102.9/100= $1.029
h) Since the discount is 4¢ per litre, the price of fuel comes down froom 102.9 - 4 = 98.9¢ = 98.9/100 $ = $0.989
i) 55L at undiscounted price = 55 x $1.029 = $56.595 rounded up to $56.60
j) With a voucher, there is a discounted price of $0.989 per litre. So for 55L, discounted price with voucher = 55 x 0.989 = $54.395 = $54.40 rounded to the nearest cent
the density of a certain material is such that it weighs 3 grams per fluid ounce of volume. express this density in ounces per liter. round your answer to the nearest hundredth.
Answers
The density in ounces per liter is 3.57826 rounding off = 3.58
Density of a substance can be defined as a relationship between the mass and the volume of that substance.
[tex]Density=\frac{Mass}{Volume}[/tex]
For Example if a metal have a mass 0f 7gm and volume as [tex]5cm^{3}[/tex]
[tex]Density=\frac{7}{5} = 1.4g/cm^{3}[/tex]
we know that 1 gram/fluid ounce of volume = 1.19275 ounces/liter
1 gm/fluid ounce =1.19275 ounces/liter
3 gm/fluid ounce = 3*1.19275 ounces/liter
So 3 gm/fluid ounce = 3.57826 ounces/liter
On rounding it to nearest hundredth we get 3.58 ounces/liter
Therefore the density of the material which weighs 3 gm/fluid ounce in ounces/liter is 3.58.

What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to make b the subject of the equation?The equation is given as
p = 1/2ab^2 + c
Subtract c from both sides of the equation
So, we have
1/2ab^2 = p - c
Multiply through by 2
ab^2 = 2(p -c)
Divide by a
b^2 = 2(p -c)/a
Take the square root of both sides
