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.

Solve - 3/5 divided by 9/10. Put your answer in simplest form.
Answer:
2/3
Step-by-step explanation:
Heres how I got 2/3
So first what we need to do is we need to figure out what 3/5 divided by 9/10 is.
So what we are going to do is we are going to do a method that my teachers toaught to me called Pemdas.
So we are going to line up 3/5 and 9/10 right next to eachother.
Then we are going to miltiply the top number of the first fraction by the bottom number of the first fraction and that will be our numerator or in other words first number in our next fraction. So that would end up being 30 because 3x10=30. So our next fraction would start with 30 so it would be 30/x because we dont have a denominator yet or in other words bottom number for our fraction.
So now what we need to do is multiply the bottom number of our first fraction by the top number of our second fraction and that will be 45 because 5 times 9 is 45. So our ansewer WOULD be 30/45 but they asked for it in the simplest form so we need to do that.
So what we need to do is start dividing the fraction 30/45 to make it the smalest fraction we can but keep in mind if you cant make this into another fraction than 30/45 is your ansewer because it is you simplest form. So what we are going to do is take 30/45 and start seeing if we can divide both of these numbers by a smaller number. So I know that 30 can be divided by 5 and so can 45 so after I divide 30 and 45 by 5 it would give me 6/9 as a fraction but wait you can divide 6/9 by 3 and if we divide 6 by 3 it would give us 2 and if we divide 9 by 3 it would give us 3 so our ansewer would end up being 2/3 and 2/3 cant be divided by anything so that IS YOUR ANSEWER 2/3. Have a wonderful day everyone!

A sample of a radioactive isotope had an initial mass of 690 mg in the
year 1997 and decays exponentially over time. A measurement in the
year 2001 found that the sample's mass had decayed to 390 mg. What
would be the expected mass of the sample in the year 2011, to the
nearest whole number?
Answer:
its 94 on deltamath just did it
Step-by-step explanation:
Let t=0 represent the year 1997
Starting Value: 690
Write function:
y=690(b)^t
Now find the b-value:
y=390 when t=4 (2001−1997)
390=690(b)^4
390/690=690(b)^4/690
0.56521739=b^4
(0.56521739)^1/4=(b^4)^1/4
0.86706944=b
Write Complete Function:
y=690(0.86706944)^t
Find value in 2011 (use t=14):
y=690(0.86706944)^14
y=93.67062063
y≈94

A bookstore costs $90 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point for this bookstore?
A. n = 12
B. n = 18
C. n = 15
D. n = 16
Answer:
Total Cost in a day is . Profit function is . And the revenue function is . In a day, bookstore must sell at least 15 books, because of 6n-90=0, in order to make profit.
Step-by-step explanation:
-90
The break-even point for this bookstore is 15, i.e. correct answer is,
C. n = 15.
Here, we have,
given that,
A bookstore costs $90 a day to keep open,
and it spends $12 for each book that it sells.
If each book sells for $18,
now, we know that,
Breakeven quantity = fixed cost / price – variable cost per unit
now, we have,
$90 / (18 - 12)
=$90 / $6
= 15
so, n = 15
Hence, The break-even point for this bookstore is 15, i.e. correct answer is, C. n = 15.

Which function shown below has the greater rate of change? Explain. (Be sure to include the
rate of change for each in your explanation).
Answer:
Function 1 has a greater rate of change.
Step-by-step explanation:
Function 1 has a rate of change of 3 because 3x is the slope of the line.
Function 2 has a rate of change of 1.5, because when you use rise/run, you get a slope of 3/2.
Function 3 has a rate of change of 2. You use the formula (y2 - y1) / (x2 - x1) to find the slope. I used (0,0) and (1,2). When you plug in 2 for y2, 1 for x2, and 0 for y1 and 0 for x1, you get (2-0) / (1-0) which is 2/1. That equals a slope of 2.

Light travels at approximately 186,000 miles per second. How is 186,000 written in scientific notation?
Answer:1.86*10^5
Step-by-step explanation:
Scientific notation is simple. First you place a decimal after the first numerical digit. Then for every digit after the decimal you would multiply by 10 to get back to the standard form. Instead of constantly multiplying by 10 you will raise the exponent.
The theater sells two types of tickets: adult tickets for $17 and child tickets for $14.
Last night, the theater sold a total of 238 tickets for a total of $3554. How many adult tickets did the theater sell last night?
Answer:
74 adult tickets
Step-by-step explanation:
Create a system of equations where a is the number of adult tickets and c is the number of child tickets:
a + c = 238
17a + 14c = 3554
Solve by elimination by multiplying the top equation by -14:
-14a - 14c = -3332
17a + 14c = 3554
Add these together, and solve for a:
3a = 222
a = 74
So, 74 adult tickets were sold last night

Monika is in charge of ordering pens for an upcoming convention. Pens
come in boxes of 6 and boxes of 8 and Monika needs at least 720 pens.
Which inequality describes this situation?
x = number of boxes of 6 pens
y = number of boxes of 8 pens
The inequality describing this situation is: 6x + 8y ≥ 720
Recall:
A situation can be described using Inequality.Inequality equation involves variables and inequality signs.Given:
number of boxes containing 6 pens = xnumber of boxes containing 8 pens = yGiven that Monika needs at least 720 pens, it means that total number of pens in boxes containing 6 and 8 pens respectively must be equal to or greater than 720.

What is the surface area of a cereal box with a height of 10 inches, a width of 4 ½ inches, and a length of 7 inches?
Answer:
Surface area of a box = 293 inches ²
Step-by-step explanation:
Surface area of a box = 2(lw + lh + hw)
Where,
l = length = 7 inches
w =width = 4 1/2 inches
h = height = 10 inches
Surface area of a box = 2(lw + lh + hw)
= 2(7*4.5 + 7*10 + 10*4.5)
= 2(31.5 + 70 + 45)
= 2(146.5)
= 293 inches ²
Surface area of a box = 293 inches ²
