Under very specific instructions, a jeweler made one ring for the queen and one ring for the princess. The gem on the queen's ring weighed 9/10 of a carat and the stone on the princess's ring weighed 7/10 of a carat. How much heavier was the stone on the queen's ring than the stone on the princess's?
Answer: 1/5
Step-by-step explanation:
From the question, we are informed that the gem on the queen's ring weighed 9/10 of a carat and the stone on the princess's ring weighed 7/10 of a carat.
To calculate how heavier the stone on the queen's ring was than the stone on the princess will be:
= 9/10 - 7/10
= 2/10
= 1/5
Adan works as an information technician and fitness trainer. As a technician, he earns $22 per hour. Last week he worked x hours as a technician and his friend paid him $50 for a day of fitness training. Write an expression to represent the total amount Adan earned last week.
Answer: t = 22x + 50
Step-by-step explanation:
t = total amount earned
x = hours worked
We know his friend payed $50, so that is our initial value. We don’t need hours for that one.
For his job as trainer, he earns $22 per hour but we don’t know how many hours he earned, so that is x. That is how I got the 22x.
Hope this helps! And of course, feel free to use any variables of your choice. :)

A car rental service charges a one-time fee of $19.99 in addition to $0.29 per mile drive. If the final total for renting the car is $73.93, select which equation best represents the situation. Let m represent the number of miles driven.
*Answer Choices*
19.99m + 0.29m = 73.93
19.99m + 0.29m = 73.93
(19.99 + 0.29)m = 73.93m
19.99 + 0.29m = 73.93
Answer:
Your answer is: D) 19.99+0.29m=73.93
We are trying to find the miles driven so therefore 0.29$ is per mile. So we have to see how many 0.29$ along with 19.99$ can fully add up to 73.93$

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.

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.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that April and bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars and 3 large chocolate bars. April paid $16.50 and bill paid $11.25.
We can write -
4x + 6y = 16.50 ... Eq{ 1 }
3x = 11.25 ... Eq{ 2 }
On solving the equation, we get -
{x} = 11.25/3
{x} = 3.75
Now, we can write -
4x + 6y = 16.50
4 x 3.75 + 6y = 16.50
6y = 16.5 - 15
6y = 1.5
y = 1.5/6
{y} = 0.25
Therefore, the cost of a large single chocolate is $0.25.

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 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
Which ones are equivalent?
40/1000 and 40%
6/5 and 120%
50/33 and 117%
1/8 and 12.5%
1/3 and 30%
Answer:
1/8= 0.125
To have a percentage, multiply by 100
0.125 x 100 = 12.5%

If you were to multiply 3X25, you would have a product of 75.
Explain 2 ways you could rewrite 25 and using the distributive property still obtain a product of 75.
Include one example using addition and the other example using subtraction. For example, if I were to rewrite the integer 72, I could choose (70 + 2) or (80 – 8).
An example with addition is 3x(20+5) as 20 plus 5 is still 25, and an example with subtraction is 3x(30-5), as 30 minus 5 is 25.
