height of 4x-2 Find the surface area and volume of the box in terms of x.
help me please
Answer:
Step-by-step explanation:
Length, L = 2x + 2
Width, W = 3x
Height, H = 4x - 2
[tex]Surface\ Area = 2 (LW + WH + HL)\\\\[/tex]
[tex]= 2 ( (2x +2)(3x) + (3x)(4x -2) + (4x - 2)(2x + 2))\\\\=2(6x ^2 + 6x + 12x^2 - 6x + 8x^2 + 8x - 4x - 4)\\\\=2(26x^2 +4x -4) \ square \ units[/tex]
[tex]Volume = L \times W \times H[/tex]
[tex]= (2x+2)(3x)(4x-2)\\\\=(6x^2 + 6x)(4x-2)\\\\=24x^3 -12x^2 + 24x^2 - 12x\\\\=24x^3 +12x^2 -12x \ cubic \ units[/tex]
The product of a number decreased by 3 and the same number increased by 8 is 80.
Answer:
-13, 8
Step-by-step explanation:
(x-3)(x+8) = 80
use FOIL to eliminate parenthesis
x² +8x - 3x - 24 = 80
combine like terms
x² + 5x - 24 = 80
move the constant to the left
x² + 5x - 104 = 0
factor x and then factor -8
x(x+13) - 8(x+13) = 0 factor (x+13)
(x+13)(x-8) = 0
separate into possible cases
x + 13 = 0
x - 8 = 0
solve
x = -13
x = 8

What is the midpoint of AB?
Answer:
[tex](-4, -\frac{1}{2})[/tex]
Step-by-step explanation:
Hi there!
We are given the line segment, with the end points AB
The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).
We want to find the midpoint of the line segment AB
The midpoint formula is given as [tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are coordinates
We have two coordinates, which is what we need, but let's label their values to avoid any confusion:
[tex]x_1=-5\\y_1=-4\\x_2=-3\\y_2=3[/tex]
Now substitute those values into the formula:
[tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex]
[tex](\frac{-5+ -3}{2}, \frac{-4+ 3}{2})[/tex]
Now simplify the numerator and denominator
[tex](\frac{-8}{2}, \frac{-1}{2})[/tex]
Simplify again:
The midpoint is (-4, [tex]-\frac{1}{2}[/tex])

A 6000-seat theater has tickets for sale at $27 and $40 How many tickets should be sold at each price for a sellout performance to generate a total revenue of 5188,000?
The number of tickets for sale at $27 should be
Using a system of equation, the Number of tickets sold at $27 is - 380615
Let :
Number of $27 tickets = a Number of $40 tickets = ba + b = 6000 - - - - (1)
27a + 40b = 5188000 - - - - - (2)
From (1) :
b = 6000 - a - - - - - - (3)Put (3) in (2)
27a + 40(6000 - a) = 5188000
27a + 240000 - 40a = 5188000
-13a = 5188000 - 240000
-13a = 4948000
a = -380615

Find the value for a for which 3y - ax = 8 and 4x + 8y = 2 are perpendicular.
Step-by-step explanation:
3y+8y=11y and -ax+4x=4ax
Answer:
a = 6
Step-by-step explanation:
Perpendicular lines have slope that are negative reciprocal of each other. There product = -1
Solve both equations for y.
3y - ax = 8 4x + 8y = 2
3y = ax + 8 8y = -4x + 2
y = ax/3 + 8/3 y = -4x/8 + 2/8
y = a/3(x) + 8/3 y = -1/2(x) + 1/4
Now you know that the slope of y = -1/2(x)+ 1/4 is -1/2
and the slope of y = a/3(x) + 8/3 is a/3.
Looking for the value of "a" that will make the lines perpendicular.
You know that one line slope is -1/2 so the other line slope is 2 because the slope are negative reciprocal. Also remember that the slope is the coefficient of the x term.
Now a/3 = 2 ; a = 6

A class has 9 boys and 18 girls. The class as a whole has a GPA (grade point average of 2.96, and the boys have a GPA of 2.40. What is the GPA of the girls? (Round your answer to two
decimal places
9514 1404 393
Answer:
3.24
Step-by-step explanation:
The weighted average GPA is ...
(9(2.40) +18g)/(9+18) = 2.96
Then the girls' GPA (g) is ...
((27)(2.96)-9(2.40))/18 = g = 58.32/18 = 3.24
The GPA of the girls in the class is 3.24.
_____
Additional comment
The solution expression can be rearranged to ...
((9+18)(2.96) -(9)(2.40))/18 = g
2.96 +(9/18)(2.96 -2.40) = g
2.96 +(1/2)(0.56) = g
That is, the difference of the boys' GPA from the overall average, multiplied by the ratio of boys to girls, is the amount that must be added to the overall average to get the girls' GPA. This is arithmetic you can do in your head.
The key idea with the average is that the sum of differences from the average is zero. If 9 boys each have a GPA 0.56 units below the average, then twice as many girls will each have a GPA that is half as much above the average.
The Royals softball team played 75 games and won 55 of them what percent of the games did they lose? (part whole percent)
Answer:
27%
Step-by-step explanation:
75-55=20
75 - 100%
20 - x%
x=20*100:75=26.(6)7~27%
Answer:
They lost 29.3% of the softball games.
Step-by-step explanation:
Total number of games = 75
Number of games won = 55
Number of games lost = 75 − 55 = 22
Percentage of games lost: Number of games lost/ total games x 100%
Which means: 22/75 x 100% = 29.3%

Answer:
-2.25 + 1 1/10 = -1.15
-2.25 + 1 2/10 = -1.05
-2.25 + 1 3/10 = -0.95
-2.25 + 1 4/10 = -0.85
-2.25 + 1 5/10 = -0.75
-2.25 + 1 6/10 = -0.65
-2.25 + 1 7/10 = -0.55
-2.25 + 1 8/10 = -0.45
-2.25 + 1 9/10 = -0.35
-2.25 + 1 8/9 = -0.361111111
-2.25 + 1 7/8 = -0.375
(-2.25) + 1 6/7 = -0.392857143
(-2.25) + 1 5/6 = -0.416666667
(-2.25) + 1 4/5 = -0.45
(-2.25) + 1 3/4 = -0.5
(-2.25) + 1 2/4 = -0.75 is the same as 1 5/10 = -2.25 + 1/2 = -0.75

Ms. Knight's two cooking classes are
making a total of 30 sweet potato
pies. Each pie requires 2 % sweet
potatoes. Her first class makes 1/3 of
the total number of pies needed.
Exactly how many sweet potatoes
will her second class need in order to
make the remaining pies?
Answer:
20
Step-by-step explanation:
In class 1, they used 10 sweet potatoes.
If they need 30, in class 2, they used 20.
The second class needs 0.4 sweet potatoes to make the remaining pies.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
If Ms. Knight's two cooking classes are making a total of 30 sweet potato pies and each pie requires 2% sweet potatoes, then the total amount of sweet potatoes needed is:
30 pies x 2% sweet potatoes per pie = 0.6 sweet potatoes
Her first class makes 1/3 of the total number of pies needed, which is:
1/3 x 30 pies = 10 pies
This means that the first class used:
10 pies x 2% sweet potatoes per pie = 0.2 sweet potatoes
So, the second class needs to make the remaining pies, which is:
30 pies - 10 pies = 20 pies
The second class needs to use:
20 pies x 2% sweet potatoes per pie = 0.4 sweet potatoes.
Therefore, the second class needs 0.4 sweet potatoes to make the remaining pies.

Step-by-step explanation:
Claire bought just enough fencing to enclose either a rectangular garden or a triangular garden, as shown. The two gardens have the same perimeter. How many feet of fencing did she buy?
Answer:
124Step-by-step explanation:
Given,
Perimeter of fencing bought by Claire for rectangular garden
= 2(4x - 4 + x - 4)
= 2 ( 5x - 8 )
= 10x - 16
Perimeter of fencing bought by Claire for triangular garden
= (3x - 1) + (3x - 1) + 3x
= 3x + 3x + 3x - 1 - 1
= 9x - 2
Since,
The two gardens have same perimeter,
By the problem,
10x - 16 = 9x - 2
=> 10x - 9x = 16 - 2
=> x = 14
Hence,
Feet of fencing bought by her,
Putting value in any of the perimeters of the gardens,
10x - 16
= 10(14) - 16
= 140 - 16
= 124 feet (Ans)
