A square box is being cut apart and has the measurements shown below. What is the surface are each square is 3.5 inches and there 6 squares
Answer:
73.5 in^2
Step-by-step explanation:
Given data
Dimension of square= 3.5 inches
Area= 3.5^2
Area= 12.25 in^2
Number of square= 6
Hence the total area is
=12.25*6
=73.5 in^2
What is the equation of the line that passes through the point (-5, 4) and has a slope of - 3/5
Step-by-step explanation:
Using point slope form ,
=> ( x - (-5) ) m = ( y - 4)
=> x + 5 = -3/5 ( y - 4)
=> 5x + 25 = -3y + 12
=> 5x + 3y + 13 = 0

Dorothy invested $80,000. Some was invested
in high-yield bonds that earned a 10% profit,
and the rest was put into “old economy" stocks
that earned a 12% profit. How much did
Dorothy invest in high-yield bonds if her total
profit on both types of investments was
$9,200?
Answer:
The amount invested in high-yield bonds was $20,000
Step-by-step explanation:
The total amount Dorothy invested = $80,000
The amount that can be earned by investing part of the amount in high-yield bonds = 10% profit
The amount that can be earned by putting the rest of the amount into "old economy" stocks = 12% profit
Dorothy's total profit = $9,200
Let 'x' represent the amount she invested in high-yield bonds, and let 'y' represent the amount she invested in "old economy" stocks, we have;
x + y = 80,000...(1)
0.1·x + 0.12·y = 9,200...(2)
From equation (1), we get;
y = 80,000 - x
Plugging in the above value of 'y' in equation (2), gives;
0.1·x + 0.12·y = 0.1·x + 0.12 × (80,000 - x) = 9,200
0.1·x - 0.12·x + 9,600 = 9,200
-0.02·x = 9,200 - 9,600 = -400
x = -400/(-0.02) = 20,000
x = 20,000
The amount Dorothy invested in high-yield bonds, x = $20,000
(∴ y = 80,000 - x = 80,000 - 20,000 = 60,000
y = 60,000
The amount she invested in old economy stocks, y = $60,000).

Consider the following pair of equations: y = x + 4 y = −5x − 2 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
(-1, 3)
Step-by-step explanation:
to solve using substitution, you have to know the value of either x or y. in this example, they gave you the value of y already: y=x+4.
this means you can substitute the y for (x+4). if we substitute y for (x+4) in the equation y=-5x-2, we get this:
(x+4)=-5x-2
then solve for x
6x=-6
so x=-1
since we know the x value, we can solve for y
y=x+4
y=-1+4
y=3
so the final answer is (-1, 3)
Answer:
(- 1, 3 )
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
y = - 5x - 2 → (2)
Substitute y = x + 4 into (2)
x + 4 = - 5x - 2 ( add 5x to both sides )
6x + 4 = - 2 ( subtract 4 from both sides )
6x = - 6 ( divide both sides by 6 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting into (1)
y = - 1 + 4 = 3
solution is (- 1, 3 )
Which is the equation of the line through the point (−3, 8) that is perpendicular to the line y=14x+12?
Answer:
y = -1/14x + 109/14
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 14x + 12. Its slope is 14. A line perpendicular to this one will have a slope of -1/14.
Plug this value (-1/14) into your standard point-slope equation of y = mx + b.
y = -1/14x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-3, 8). Plug in the x and y values into the x and y of the standard equation.
8 = -1/14(-3) + b
To find b, multiply the slope and the input of x (-3)
8 = 3/14 + b
Now, subtract 3/14 from both sides to isolate b.
8 - 3/14 = b
112/14 - 3/14 = b
109/14 = b
Plug this into your standard equation.
y = -1/14x + 109/14
This equation is parallel/perpendicular to your given equation (y = 14x + 12) and contains point (-3, 8)
Hope this helps!

Evaluate the expression below when n = 2.4. If needed, answer as a fraction or a decimal.
12n−8
Answer:
20.8
Step-by-step explanation:
Plug in 2.4 as n in the expression, and simplify:
12n - 8
12(2.4) - 8
28.8 - 8
= 20.8
So, the answer is 20.8
Find the IQR (interquartile range).
19, 21, 18, 17, 18, 22,46
Answer:
4.
Step-by-step explanation:
Step 1: Formula.
[tex]IQR=Q3-Q1[/tex]
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 2: Explain/define.
The interquartile range is the difference between quartile 3 and quartile 1.Quartile 1 is the median of the upper half of a data set.Quartile 3 is the median of the lower half of a data set.The median is the 'middle value.'--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 3: Order/arrange.
In order to find the median, you must first put the numbers in numerical order.
19, 21, 18, 17, 18, 22, 46
↓
17, 18, 18, 19, 21, 22, 46
The lower half of the data set, not including the median of the whole data set, is 17, 18, and 18.
The upper half of the data set is 21, 22, and 46.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 4: Solve.
17, 18, 1821, 22, 36Next, we find the medians of both sets.
The median of the lower half is 18 (Q1).
The median of the upper half is 22 (Q3).
Lastly, we subtract Q3 from Q1.
[tex]22-18=4.[/tex]
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 5: Conclude.
I, therefore, believe the interquartile range of this data set is 4.

In 2002, the membership of a club totaled 5 thousand. By 2005, there were 29 thousand members of this club.
a. Write two ordered pairs of the form (x,y), where x is years after 2002 and y is membership in thousands.
b. Assume that the membership is linear between the years 2002 and 2005. Use the ordered pairs from part (a) to write an equation in slope-intercept form of the line
relating year and membership.
c. Use the linear equation from part (b) to predict membership in 2014.
Answer:
a)
(0, 5)
(3, 29)
b) y = 8x + 5
c) 101 thousand
Step-by-step explanation:
slope m = (29-5)/(3-0) = 24/3 = 8
y-intercept = (0, b) = (0, 5)
y = mx + b
y = 8x + 5
2014 - 2002 = 12
y = 8(12) +5
y = 96 + 5 = 101
