College student makes decorative Styrofoam Lions and Husky's which she sells each year. Each one uses 8 oz of Styrofoam and takes 35 minutes to make. Each husky uses 12 oz of Styrofoam and takes 20 minutes to me. Furthermore, each line brings in a profit of $2.50 while each husky brings in a profit of $3. If she only has 3840 ounces of Styrofoam to work with and has 9650 minutes, how many of each animal should she make in order to maximize profits? What is the maximum profit possible?
Answer:
She should make 122 Styrofoam lions and 268 Styrofoam Husky's
The maximum profit, she makes is $1109
Step-by-step explanation:
The given information are;
The volume required to make each lion = 8 oz
The time it takes to make each lion = 35 minutes
The amount of profit each lion brings = $2.50
The volume required to make each Husky = 12 oz
The time it takes to make each Husky = 20 minutes
The amount of profit each Husky brings = $3
Let the number of lion Styrofoam cups she makes = x
Let the number of Husky Styrofoam cups she makes = y
Therefore, we have;
x × 35 + y × 20 = 9650..........(1)
x × 8 + y × 12 = 3840.............(2)
Dividing equation (2) by 8 and making x the subject, we get;
x × 8/8 + y × 12/8 = 3840/8
x + 4/3·y = 480
x = 480 - 4/3·y
Substituting the value of x in equation (1) gives;
(480 - 4/3·y) × 35 + y × 20 = 9650
16800 - 80/3·y = 9650
y = 268.125
x = 480 - 4/3·y = 480 - 4/3×268.125 = 122.5
Therefore, she can make 122 Styrofoam lions and 268 Styrofoam Husky's
The maximum profit, she makes is therefore given by the following equation;
The maximum profit = 122 × 2.5 + 268 × 3 = $1109.

True or false: When you multiply or divide an inequality by a negative, you flip the inequality sign
Plz tell me
Answer:
[tex]\boxed {\tt True}[/tex]
Step-by-step explanation:
This is true. Whenever you divide or multiply an inequality by a negative number, you must flip the inequality sign.
Here is an example:
[tex]-9x>27[/tex]
We have to divide both sides of the inequality by -9. Since it is a negative number, flip the inequality sign.
[tex]\frac{-9x}{-9} <\frac{27}{-9}[/tex]
[tex]x<\frac{27}{-9}[/tex]
[tex]x<-3[/tex]
So, it is true that you must flip the inequality sign when multiplying or dividing by a negative number.
Answer:
true
Step-by-step explanation:

Taylor multiplied 8.25 x 104 and 0.4 x 104 and got 8.65 x 104
Explain Taylor's mistake and give the correct answer. (1 pt. for the explanation and 1 pt. for the correct answer.)
Answer:
Taylor added. The correct answer is 3.3*10^8
Step-by-step explanation:
Taylor haven't consider the exponents properties and multiplication was also incorrect.
What are exponents?Exponent refers to how many times a number multiplied by itself.
Given:
8.25 x [tex]10^{4}[/tex] and 0.4 x [tex]10^{4}[/tex]
Now, multiplying by considering exponents as
a^m * a^n = a^( m+ n)
So,
=8.25 * 0.4 * [tex](10) ^{4+4}[/tex]
= 3.3 * [tex]10^8[/tex]
Hence, Taylor haven't consider the exponents properties and multiplication was also incorrect.

A family of five went out to dinner at HogTastic Pit BBQ. They all ordered the buffet and drink at $12.80 each. They left a 15% gratuity for the waitress on the after-tax bill. Based on a tax rate of 7.5%, they ended up paying a total of $ for dinner.
Answer:
$79.12
Step-by-step explanation:
Given the following :
Cost per order = $12.80
Number of people = 5
Gratuity left for waitress = 15%
Tax rate = 7.5%
Total bill before tax:
$12.80 * 5 = $64
Bill after tax:
$64 * (1 + 7.5%)
64 - 4.8
= $68.80
Final amount paid:
After tax bill + (after tax bill * Gratuity rate)
$68.80 + (68.80 * 15%)
= $79.12

A dad has three sons. He shares an amount of $30,000 among his three sons. One son deposited his amount in a bank that provides him interest at the rate of 7%. The second son deposited his sum in a mutual fund that gave him returns at a rate of 8%. The third son invested his in another bank that provided him an interest rate of 6%. The second sons share is 1000 more than that of the third son. The total interest that they got was $2110. Calculate each person's share if the first sons share is equal the second son and the third son put together.
Answer:
First son receives $15000
Second son receives $8000
Third son receives $7000.
Step-by-step explanation:
Let first son receive $x and deposit it at 7%
Second son receive $y and deposit in 8%
Third son receive $z and deposit in 6%
Now, let's set up equation using the given information.
The second son share is 1000 more than the third son.
So, we can set up equation as
y= 1000+z
First son share is equal the second son and the third son put together.
So, x=y+z
And we can set up equation for total 30000 as
x+y+z=30000
Plug in y as 1000+z and x as y+z
We get third equation as
y+z+1000+z+z=30000
Plug in again y as 1000+z
It gives,
1000+z+z+1000+z+z=30000
Combine like terms,
2000+4z=30000
Subtract both sides 2000
4z=28000
Divide both sides by 4
z=7000
Now, plug in z as 7000 into y=1000+z to get y =8000
Now, x =y+z plug in the y and z values
x= 8000+7000=15000
Let's check with interest,
15000(7%)+8000(8%)+7000(6%)=2110
1050+640+420= 2110
2110=2110.

a. Assuming that the number of users continues to triple each year, for the next three years, determine the number of users in 2006, 2007, and 2008.
How many users were there in 2006?
Answer:
9 million
Step-by-step explanation:
3 million × 3 = 9 millionI hope this helps!
The number of users in 2006, 2007, and 2008 will be 9 million, 27 million, and 51 million respectively.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
It is given that, the approximate number of users has tripled each year and in 2005 there were 3 million users of social media.
The number of users in 2006 = 3 × number of users in 2005]
The number of users in 2006 = 3 × 3 million
The number of users in 2006 = 9 million
The number of users in 2007 = 3 × number of users in 2006
The number of users in 2007 = 3 × 9 million
The number of users in 2007 = 27 million
Thus, the number of users in 2006, 2007, and 2008 will be 9 million, 27 million, and 51 million respectively.

A technician is launching an aerial firework from a tower. The height of the firework is measured in feet and the time is measured in seconds. A function that models the fireworks vertical distance with no respect to time,x, is f(x)=-16x^+96x+112 What information does this form of equation give about the firework
Answer:
The equation gives only the total vertical distance traveled by the firework or maximum height reached by the firework
Step-by-step explanation:
Given;
A function that models the fireworks vertical distance with no respect to time,x, as;
f(x)=-16x^+96x+112
The equation gives only the total vertical distance traveled by the firework, it does not account for the position of the firework at a particular time.
Thus, with the given function we can only estimate the maximum height reached by the firework.
