A local fish market is selling fish and lobsters by the pound. The fish, f, costs $4.25 a pound, while the lobster, l, costs $9.00 a pound. The fish market sells 25.5 pounds and makes $196.25. How many pounds of fish and pounds of lobster did the market sell?
9514 1404 393
Answer:
7 pounds of fish18.5 pounds of lobsterStep-by-step explanation:
Let x represent the number of pounds of lobster sold. Then 25.5-x is the number of pounds of fish. The total money made is ...
4.25(25.5-x) +9.00x = 196.25
4.75x + 108.375 = 196.25 . . . . . simplify
4.75x = 87.875 . . . . . . . . . . . subtract 108.375
x = 18.5 . . . . . . . . . . . . . . . divide by 4.75
The market sold 7 pounds of fish and 18.5 pounds of lobster.
You estimate that the length of your
classroom is 20 feet. The actual length is 25
feet. Find the percent of error.
Answer:
The percent error is 20%.
Step-by-step explanation:
The general formula is to subtract the actual value from the estimated value, take the absolute value of the difference, divide that answer by the actual value, then multiply it by 100.
So, 20 (estimated) minus 25 (actual) is -5. The absolute value of -5 would be 5, since absolute value is always positive. Divide 5 by the actual value, 25, and you get 0.2. Multiply 0.2 by 100 to get a percent value, and the answer will amount to 20%. Hope this helps.

How can you apply the information you learn in your math courses in your daily life? How will it benefit you in the future?
Math can help you if you ever wanna build a desk in the future;)
Maths can be used in the day-to-day shopping at home groceries and vegetables etc.
What is maths?Numbers, formulae, and related structures, shapes, and the spaces in which they are contained, as well as quantities and their variations, are all covered in the field of mathematics.
An example of daily life is if you are going to the market to purchase fruits the cost of 1 kg of apple is 200rs but you want to buy 30 rs apple only. Then the amount in kg for the 30rs apple will be calculated by using maths.
200rs apple = 1 kg
1 rs apple = 1 / 200 kg
30 rs apple = ( 1 x 30 ) / 200
30 rs apple = 0.15 kg or 150 grams
In this way, you will get the exact amount of apple for 30 rupees amount by using mathematics
Therefore, maths can be used in the day-to-day shopping at home groceries and vegetables, etc.

A contractor purchases 5 dozen pairs of padded work gloves for 71.40 he incorrectly calculates the unit price as 14.28 per Pair for the expense report . What is the correct unit price ? What is the error?
Answer:
0%
Step-by-step explanation:
Step one:
given data
A contractor purchases 5 dozen pairs of padded work gloves for $71.40
the unit price will be
total number of gloves
5 pairs
unit cost per glove
=71.40/5
=$14.28 per glove
The estimated cost per pair is
$14.28 per pair
The error is
%Error= real price -estimated /estimated*100
%Error= 14.28-14.28/14.28*100

Find the perimeter and area of this shape
Answer:
Area: 38.48u² Perimeter: 24.995u
Step-by-step explanation:
This is a quarter of a circle. You can use the formula to find the area of a full circle and then divide it by 4 to find the area of a quarter circle.
The radius is 7. So..
A = πr²/4 = π × 7²/4
= π × 49/4
= 12.25π
≈ 38.48u²
You have to find the circumference of the full circle in order to find the perimeter of this shape. The circumference is πd.
To find the diameter of a circle you multiply the radius by 2.
7 × 2 = 14
P = π14
≈ 43.98
Then, you divide that number by 4 because the arc (the curved part) is a quarter of the circumference.
43. 98 ÷ 4 = 10.995 - This is the length of the arc.
Now you add all the measurements:
7 + 7 + 10.995 = 24.995u

[tex]We\ are\ given\ that:\\AB\ is\ a\ Line\ Segment\ that\ has\ Points\ A\ and\ B,\ that\ are\ it's\ two\ End-Points.\\Now,\\Point\ C\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AC\ and\ CB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:2.\\\\Point\ E\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AE\ and\ EB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:3.\\\\Point\ D\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AD\ and\ DB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:4.\\\\[/tex]
[tex]Now,\\For\ Point\ C,\\Total\ no.\ of\ parts=1+2=3\\Length\ of\ AC=\frac{1}{3}x\\Length\ of\ CB=\frac{2}{3}x\\\\For\ Point\ E,\\Total\ no.\ of\ parts=1+3=4\\Length\ of\ AE=\frac{1}{4}x\\Length\ of\ EB=\frac{3}{4}x\\\\For\ Point\ D,\\Total\ no.\ of\ parts=1+4=5\\Length\ of\ AD=\frac{1}{5}x\\Length\ of\ DB=\frac{4}{5}x\\[/tex]

If a original image is 2 inches and a scale drawing is 3.5 inches what is the scale factor?
Answer:
Step-by-step explanation:To find the scale factor of an original and a scale drawing, set up a ratio of the original length and the length of the drawing. Then simplify the ratio. A scale factor may be expressed by the ratio or by a positive number.A scale factor expresses the relationship between two lengths. It can be expressed as a ratio or a positive number. Let's look at some examples. If the original image is 4 inches, and the scale drawing is 8 inches, we can say that the scale factor is 4:8, but we must simplify that ratio, making it 1:2. We can also write the scale factor as a number by dividing 8 by 4 for a scale factor of 2.
That example is pretty straightforward, but let's look at something a bit more complicated. Let's say we have an original image that is 4 inches and a scale drawing that is 9.5 inches, and we want to find the scale factor. We cannot write the ratio 4:9.5, because ratios do not allow decimals or fractions. We must simplify the ratio. This involves getting rid of the decimal. To do this, we multiply 9.5 by 2 and get 19. What we do to one element of the ratio, we must do to the other, so we multiply 4 by 2 for 8. Our ratio looks like this: 8:19. Because 19 is a prime number, we cannot simplify further. This scale factor of 8:19, then, tells us that for every 8 inches in the original, the scale drawing will have 19 inches. We can also express the scale factor as 2.375 (19 divided by 8).
We'll try one more example. We have an original image that is 1.25 inches and a scale drawing that is 4 inches. Again, we cannot write a ratio with decimals, so we can't leave our scale factor as 1.25:4. We must simplify. This time, we must get rid of the decimal by multiplying each side by 4, so we have 5:16. We cannot simplify this ratio any further, but we can express it by the number 3.2 (16 divided by 5).

[tex]\huge\boxed{\tt{x = 11 , y = 1}}[/tex]
Step-by-step explanation:
x + y = 12 -------------------------(1)
2x + 5y = 27 --------------------(2)
Multiply (1) by 2
2(x+y) = 12 * 2
2x + 2y = 24 --------------------(3)
Subtract (3) from (2)
2x + 5y - ( 2x + 2y ) = 27 - 24
2x + 5y - 2x - 2y = 3
5y - 2y = 3
3y = 3
Divide 3 to both sides
y = 1
Put y = 1 in (1)
x + 1 = 12
x = 12 - 1
x = 11
So,
x = 11 , y = 1

This graph shows the relationship between the pounds of cheese bought at a deli and the total cost, in dollars, for the cheese. Identify the constant of proportionality represented in the graph.
Answer:
y = 4x
Step-by-step explanation:
formula is y=kx, where k is factor of proportionality
Looking at the graph where y and x meet...
2/0.5 = 4 so 2 = 4(0.5)
Therefore, 4 is k (constant)
4=4(1)
6=4(1.5)
10=4(2.5)
and so on...
