Answer:
x + 12 + 16 = 100
72 fishes
Step-by-step explanation:
Given parameters:
Number of days fished = 3days
Number of fishes caught = 100 fishes
Number of fish caught on day 2 = 12fishes
Number of fish caught on day 3 = 16fishes
Unknown:
Number of fish caught on the first day = ?
Solution:
Let the number of fishes caught on the first day = x;
Total number of fishes caught = No of fish on day 1 + No of fish on day 2 + number of fish on day 3
Insert the parameters and solve;
100 = x + 12 + 16
x = 100 - 28 = 72fishes

Write the equation of a line with an x-intercept of 4 and a y-intercept of -3.
Answer:
y = [tex]\frac{3}{4}[/tex] x - 3
Step-by-step explanation:
Coordinates of x-intercept are (x, 0)
Coordinates of y-intercept are (0, y)
(0, - 3)
(4, 0)
Slope m = [tex]\frac{3}{4}[/tex]
y = [tex]\frac{3}{4}[/tex] x - 3
y = [tex]\frac{3}{4}[/tex] ( - 4) - 3 = - 6
(- 4, - 6)
y = [tex]\frac{3}{4}[/tex] ( - 16) - 3 = - 15
(- 16, - 15)
12 = [tex]\frac{3}{4}[/tex] x - 3
[tex]\frac{3}{4}[/tex] x = 15
x = 20
(20, 12)

Answer:
3. markup: $150
selling price: $300
4. markup: $19.20
selling price: $67.20
5. markup: $55
selling price: $165
6. markup: $90
selling price: $450
7. markup: $3.75
selling price: $16.25
8. markup: $7.14
selling price: $27.54
Step-by-step explanation:
To find the markup of an item you multiply the initial value of the item by the percentage it's being marked up by. To find the selling price, you add the markup to the initial value. Let's use question 3 as an example:
3. The recliner is being marked up by 100%. To find the markup, we can convert 100% into decimal form and then multiply it by the initial value 150:
100% = 1
150 * 1 = 150
The markup is 150.
To find the selling price we add the markup to the initial value:
150 + 150 = 300
The selling price is 300.
I applied this method to all of the questions.

What is the slope of(20, 8) (19, 10)
Answer:
-2
Step-by-step explanation:
8-10 = -2
20-19 = 1
-2/1 = -2
Answer:
-2
Step-by-step explanation:
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex] Where y2 is 8 and x2 is 20 and y1 is 10 and x1 is 19
So 8 - 10 = -2
And 20 - 19 = 1
-2 divided by 1
It is -2.

3z - 4 = 52 - 12
Answer:
z=44/3
Step-by-step
Subtract the numbers 52-12=40
3z-4=40
Add 4 to both sides
3z-4+4=40+4
SImplify
3z=44
Divide both sides by 3
3z/3 = 44/3
z=44/3 or decimal form= 14.66

Which inequality is true?
A. 1/2 < 1/3
B. 3/4 > 2/3
C. -1/4 < - 2/3
D. -1 > 3/4
Answer:
Option B. 3/4 > 2/3 is the correct answer.
Step-by-step explanation:
Lets look at the options one by one
A. 1/2 < 1/3
This inequality converts into 0.5<0.33 which is false.
B. 3/4 > 2/3
This simplifies to 0.75>0.666 which is true.
C. -1/4 < - 2/3
This converts to -0.25<-0.666 which makes the inequality false.
D. -1 > 3/4
This converts to -1>0.75 which makes the inequality false.
Hence,
Option B. 3/4 > 2/3 is the correct answer.
Answer:
Option C. -1/4 < - 2/3 is the correct answer.
-1/4 equals -3/12
-2/3 equals -8/12
So, it is -2/3 is greater

Answer:
The gradient of the graph below is [tex]\mathbf{\frac{3}{2} }[/tex]
Step-by-step explanation:
We need to calculate the gradient of the graph
The gradient of graph is actually slope of the graph.
The slope of graph can be calculated using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Taking any 2 points on graph i.e
(1,0) and (-1,-3)
We have [tex]x_1=1, y_1=0, x_2=-1,y_2=-3[/tex]
Putting values and finding gradient:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-3-0}{-1-1}\\Slope=\frac{-3}{-2}\\Slope=\frac{3}{2}[/tex]
So, The gradient of the graph below is [tex]\mathbf{\frac{3}{2} }[/tex]
A firm producing poultry feeds finds that the total cost C(x) in dollars of producing and selling x units is given by
C(x) - 20x+100. Management plans to charge $24 per unit for the feed. How many units must be sold for the firm to break even?
Answer:
Break-even point in units= 25
Step-by-step explanation:
Giving the following information:
Fixed cost= $100
Unitary variable cost= $20
Selling price per unit= $24
To calculate the break-even point in units, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 100 / (24 - 20)
Break-even point in units= 25

Explanation:
Plug x = 80 into the equation to get
y = 0.12x
y = 0.12*80
y = 9.60
This means the store paid $9.60 for the rope. This amount of money is leaving the store owner's wallet or bank account. We'll keep this in mind for later.
-------------------
The graph shows the equation y = 0.20x
Note how the point (1, 0.20) is on the line to help see the slope right away. This trick only works when the line goes through the origin.
You could also use the slope formula to get this. The y intercept is 0 since the line goes through the origin.
This equation and graph show that the price per foot is $0.20, or it's 20 cents per foot.
Plug in x = 80 to find how much the store will make in revenue
y = 0.20x
y = 0.20*80
y = 16
The store makes $16 in revenue when it sells 80 ft of rope.
----------------------
The cost to the store was $9.60 found in the first section. The revenue was $16 found in section 2.
So,
profit = revenue - cost
profit = 16 - 9.60
profit = 6.40 dollars
A biking track has a length of 3168 feet (ft). How long is this in miles (mi)?
First fill in the blank on the left side of the equation using one of the ratios. Then write your answer on the right side of the equation.
Answer:
0.6 miles
Step-by-step explanation:
Given that,
A biking track has a length of 3168 feet (ft).
We need to find the distance in miles.
We know that, 1 mile = 5280 foot
1 feet = (1/5280) mile
Now, we can find the distance in miles by multiplying 3168 by (1/5280).
[tex]d=3168 \times \dfrac{1}{5280}\\\\=0.6\ \text{miles}[/tex]
So, the distance covered is 0.6 miles.
The sum of two real numbers is 8 and their product is 14. What is the sum of their reciprocals?
Answer:
Step-by-step explanation:Let our two numbers be a and b . Then we can see that a+b=8 and ab=15 . Now consider
(a+b)3=a3+3a2b+3ab2+b3 by the binomial expansion. Now we have all the information to solve this, observe since a+b=8 and ab=15 . We have
(8)3=a3+3ab(a)+3ab(b)+b3
a3+b3+3ab(a)+3ab(b)=83
a3+b3+3ab(a+b)=83
a3+b3=83−3ab(a+b)
a3+b3=83−3(15)(8)=512−360=152
You can also observe that 3 and 5 fulfill those conditions so, then 33+53=27+125=152 . Which is our result.
