The cardboard box below is used by a company to package new laptops of the company plans to increase the length of the Box by 2in what is the minimum amount of extra cardboard needed to construct a new box The dimensions of the box is 5 in high 16 in in width and 20 in in length
A. 84in^2
B. 116in^2
C.132in^2
D.160in^2
The minimum amount of extra cardboard needed to construct a new box is : 84in².
What is the minimum amount of extra cardboard needed?First step
Surface area=2(16) (5) in²+ 2(20in) (5in) + 2(16in) (20in)
Surface area=1000in²
Second step
Surface area if the length increase by 2 inches
Surface area=2(16) (5) + 2(20+2) (5in) + 2(16in) (20+2)
Surface area=1084in²
Third step
Surface area=1084in²-1000in²
Surface area=84in²
Therefore the minimum amount of extra cardboard needed to construct a new box is : 84in².

Susan can maximum spend $30.95 on dog food and the inequality to manage her bill is 150C + 30D ≤ 3250.
What is inequality?The idea of inequality, which is the state of not being equal, especially with regard to status, rights, and opportunities, is at the core of social justice theories. However, because it frequently has diverse meanings to different people, it is prone to misunderstanding in public discourse. However, some distinctions are shared.
Given, Susan is required to buy pet food for her local pet shelter. She buys food for both dogs and cats, but the dog food costs twice what the cat food costs. She needs to feed 150 cats and 30 dogs. Her budget is $3250
Let the price of cat food be C and the price of dog food be D.
Since the price of both cants is exceed 3250. Thus,
inequality shows their relationship is
150C + 30D ≤ 3250
Also given, the price of dog food is twice the price of cat food
C = D/2
150D/2 + 30D ≤ 3250
105D ≤ 3250
D ≤ 3250/105
D ≤ 30.95
Therefore, The most Susan can spend on dog food is $30.95, and the inequality to handle her bill is 150C + 30D ≤ 3250.

30 pts ! The height of the Ferris wheel in feet can be represented by the function 50 cos (π/15(x-10))+52 with time in x seconds. When does the height of 80 feet occur on the interval 0
The time that the height of 80 feet occur on the interval 0 is 4.662 seconds.
Given:
50 cos (π/15(x-10))+52
Height=80 feet
Time= x second
Hence:
height (h)= 50 cos [pie(x - 10 )/15 ] + 52
80 = 50 cos [pie( x - 10 )/15 ]+ 52
Collect like terms
80 - 52 = 50 cos [ pie( x - 10 )/15 ]
28 = 50 cos [ pie( x - 10 )/15 ]
cos [pie( x - 10 )/15 ] = 28/50
cos [ pie( x - 10 )/15 ] =56
cos [pie( x - 10 )/15 ]= cos ( 56 )
cos [ pie( x - 10 )/15 )]= cos ( 0.3111 pie )
Hence:
pie( x - 10 )/15 = 0.3111
( x - 10 )/15 = 0.3111
x - 10 = 15 × 0.3111
x - 10 = 4.662
x = 10 + 4.662
x = 14.662 seconds
Therefore the correct option is C.

A grocery chain runs a prize game by giving each customer a ticket that may win a prize when the box is scratched off. Printed on the ticket is a dollar value ($500, $100, $25) or the statement "This ticket is not a winner." Monetary prizes can be redeemed for groceries at the store. Below is the probability distribution of the amount won on a randomly selected ticket. Which of the following are the mean and standard deviation, respectively, of the winnings? * 2 points Captionless Image $156.25 $53.85 $15.00, $2900.00 $15.00, $26.93 $15.00, $53.85 $156.25, $26.93
Answer:
[tex]Mean = \$15[/tex]
[tex]Standard\ Deviation = \$53.85[/tex]
Step-by-step explanation:
Given
See attachment for probability distribution
Required
Determine the mean and the standard deviation
The mean of the distribution is:
[tex]Mean = E(x)[/tex]
and
[tex]E(x) = \sum x * P(x)[/tex]
So, we have:
[tex]Mean = \$500 * 0.01 + \$100 * 0.05 + \$25 * 0.20 + \$0 * 0.74[/tex]
[tex]Mean = \$5 + \$5 + \$5 + \$0[/tex]
[tex]Mean = \$15[/tex]
So:
[tex]E(x) = 15.00[/tex]
The standard deviation of the distribution is:
[tex]S = \sqrt{Var(x)}[/tex]
Where:
[tex]Var(x) = E(x^2) - (E(x))^2[/tex]
[tex]E(x^2) = \sum x^2 * P(x)[/tex]
So, we have:
[tex]E(x^2) = 500^2 * 0.01 + 100^2 * 0.05 + 25^2 * 0.20 +0^2 * 0.74[/tex]
[tex]E(x^2) = 2500 + 500 + 125 +0[/tex]
[tex]E(x^2) = 3125[/tex]
So:
[tex]Var(x) = E(x^2) - (E(x))^2[/tex]
Where
[tex]E(x^2) = 3125[/tex]
[tex]E(x) = 15.00[/tex]
[tex]Var(x) = 3125 - 15^2[/tex]
[tex]Var(x) = 3125 - 225[/tex]
[tex]Var(x) = 2900[/tex]
Recall that:
[tex]S =\sqrt{Var(x)[/tex]
[tex]S =\sqrt{2900[/tex]
[tex]S =53.85[/tex]

Equations of ellipse
[tex]\frac{(x-h)^{2} }{a^{2} } +\frac{(y-k)^{2} }{b^{2} } =1[/tex] (for horizontal major axis ,a>b)
[tex]\frac{(x-h)^{2} }{b^{2} } +\frac{(y-k)^{2} }{b^{2} }=1[/tex] ( for vertical major axis, b>a))
Where, (h, k) is the center of ellipse.
What is major axis of an ellipse?The major axis of an ellipse is its longest diameter(a line that runs through the center and both foci, with ends at the two most widely separated points on perimeter).
Formula for calculating the length of major axislength of major axis = 2a (where a is the length of semi major axis)
What is minor axis of an ellipse?The minor axis of an ellipse is the line that contains the shorter of the two line segments about which the ellipse is symmetrical.
Formula for calculating the length of minor axislength of minor axis = 2b (where b is the length of semi minor axis)
According to the given question

A) [tex](4x^{2} +32x)+(25y^{2} -250y)+589=0[/tex]
[tex]4(x^{2} +8x)+25(y^{2} -10y)+589=0[/tex]
[tex]4(x^{2} +8x+b^{2} )-4b^{2} +25(y^{2} -10y+b^{2} )-25b^{2} +589=0[/tex]
[tex]4(x^{2} +8x+4^{2})-4(4^{2})+25(y^{2} -10y+b^{2} )-25(5^{2} ) +589=0[/tex]
[tex]4(x+4)^{2}+25((y-5)^{2} )-100=0[/tex]
[tex]4(x+4)^{2} +25(y-5)^{2} =100[/tex]
dividing both the sides by 100
[tex]4\frac{(x+4)^{2} }{100} +25\frac{(y-5)^{2} }{100} =1[/tex]
[tex]\frac{(x+4)^{2} }{25} +\frac{(y-5)^{2} }{4} =1[/tex]
[tex]\frac{(x+4)^{2} }{5^{2} } +\frac{((y-5)^{2} }{2^{2} }=1[/tex]
here, h=-4 and k=5
major axis =2a=2×5=10
minor axis=2b=2×2=4
⇒ the length of major axis is not twice the length of minor axis.

minor axis :2b=4
⇒ the length of major axis is not the twice of minor axis.

Answer:
85 hours
Step-by-step explanation:
Number of hours per day = 13 hours
Number of days = 6
Number of hours worked for 6 days = 6 days × 13 hours
= 78 hours
then he worked 7 hours
Total Number of hours worked = Number of hours worked for 6 days + 7 hours
= 78 hours + 7 hours
= 85 hours
Total Number of hours worked = 85 hours
Need some assistance yall look at picture :) Algebra 2 type vibe
Answer:
It is C.
III is saying that the two functions are inverse functions. If two functions, f(x) and g(x) are inverse, then f(g(x)) = x and g(f(x)) = x. Therefore, we see that if III is true, then I and II should also be true. Now, all we have to prove is that f(x) and g(x) are inverse functions. As we said before, if two functions are inverse, then f(g(x)) = x and g(f(x)) = x.
f(g(x)) = 3([tex]\sqrt[3]{\frac{x-2}{3} }[/tex])^3 + 2
f(g(x)) = 3[(x-2)/3]+2
f(g(x)) = x-2 + 2
f(g(x)) = x
Therefore, we have proved that f(g(x)) = x, and so f(x) and g(x) are inverse functions, and so all of I, II, and III are true. Thus, the answer is C.
fyi, we didn't have to do g(f(x)) because if f(g(x)) = x, then so will g(f(x)).
