7 hours Serenity worked if she made a total of $262. 50.
How do you calculate total hours in a number?
To find the total hours, subtract the time the employee clocked in from when they clocked out.
We can start by using the following equation to find the total number of hours Serenity worked:
Total Earnings = (Hourly Wage) * (Number of Hours) + (Tips)
In this case, we know that Serenity's total earnings were $262.50, she earned $12.50 per hour and made $175 in tips on Saturday. So we can substitute these values into the equation:
$262.50 = ($12.50) * (Number of Hours) + $175
To find the number of hours, we can subtract the tips from the total earnings and divide by the hourly wage:
Number of Hours = ($262.50 - $175) / $12.50
= $87.50 / $12.50
= 7
So Serenity worked 7 hours on Saturday.
Hence, 7 hours Serenity worked if she made a total of $262. 50.

Sharon and Sue are making muffins. Sharon uses 3 cups of milk, and Sue uses 1 pint of milk. Who uses the greater amount of milk? Explain.
answer:
Sharon used more milk because 3 cups equal 1.5 (one and a half) pints.
Detailed answer:
1 cup equals 0.5 pints or half of a pint. So if you take 0.5 and multiply it by 3 you get 1.5 and that is the amount of pints that Sharon uses but Sue uses 1 pint or 2 cups. so 1.5 pints is grater than 1 pint by 0.5

Equations with three variables that are linear. Ax + by + cz = r is referred to as a linear equation in three variables.
what is linear equation ?A linear equation is one that has the form y=mx+b in algebra. It's usual to refer to the previous clause as a "linear equation with two variables" because y and x are variables. The two-variable linear equations known as bivariate linear equations. There are several instances of linear equations: 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. It is referred to as being linear when an equation has the form y=mx+b, where m stands for the slope and b for the y-intercept.

Solve by substitution.
6x +Зу = 15
x – 2y = 10
Answer:
y=5 , x= 20
Step-by-step explanation:
6x + 3y = 15
x - 2y = 10
make x subject of the formula in equation two
therefore x = 10 - 2y
substitute the value of x in equation one
6 ( 10 - 2y) + 3y = 15
60 - 12y + 3y = 15
-9y = -45
y = 5 and x = 20
Answer:
{x,y} = {4,-9}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = -6x + 15
// Plug this in for variable y in equation [2]
[2] -7x - 2•(-6x+15) = -10
[2] 5x = 20
// Solve equation [2] for the variable x
[2] 5x = 20
[2] x = 4
// By now we know this much :
x = 4
y = -6x+15
// Use the x value to solve for y
y = -6(4)+15 = -9
Solution :
{x,y} = {4,-9}

13. The number of pictures your printer
can print are shown in the table. Find
the rate in pictures per minute.
Minutes 2 4 6
8
Pictures 16 32 48 64
15.
16
Answer: The table shows the number of pictures that a printer can print at different intervals of time (measured in minutes). To find the rate in pictures per minute, we need to divide the number of pictures printed by the number of minutes it took to print them.
For example, at 2 minutes the printer printed 16 pictures. The rate of pictures printed per minute is 16 pictures / 2 minutes = 8 pictures/minute.
Similarly, at 4 minutes the printer printed 32 pictures. The rate of pictures printed per minute is 32 pictures / 4 minutes = 8 pictures/minute
And, at 6 minutes the printer printed 48 pictures. The rate of pictures printed per minute is 48 pictures / 6 minutes = 8 pictures/minute.
And, at 8 minutes the printer printed 64 pictures. The rate of pictures printed per minute is 64 pictures / 8 minutes = 8 pictures/minute.
From this it can be seen that the printer has a constant rate of 8 pictures per minute, independent of the number of minutes, it is producing 8 pictures/min.
The value 15 is not related to the table, so it's not the rate, and 16 is not the rate either, it is the number of pictures printed at 8 minutes.

3. During Their football season, the Kickerton Kangaroos had a combined total of 16 fumbles. each of the 8 players had the same amount of fumbles. how many fumbles did each player have?
4. If you multiply me by 7, then subtract 2, and then divide by 6, you get 9. what number am I?
Answer:
1. 22
2. 7*3=21
3. 2
4. 8
Step-by-step explanation: (I am not sure what level math you are as you put HS but I used simple algebra in my answers)
1. Using algebra I put the missing variable as x.
"add 5 to me" is x+5.
"divide by 9, you get 3"
[tex]\frac{x+5}{9}[/tex] = 3
Begin solving by multiplying 9 to the 3 on the other side
x+5 = 27
Subtract 5 to get x by itself
x = 22
2. An equivalent multiplication sentence can be found using algebra.
21 ÷ 7 = 3 can be rewritten as [tex]\frac{21}{7} =3[/tex]
Using algebra we know if we multiply 7 onto both sides we end up with
7*3=21
3.

I would draw this out. You have 8 players and 16 fumbles to allocate to them. You can draw tallies and allocate them to each player. You'll find that the first time they all have the equal amount is when they all have 1 fumble. The next time they all have an equal amount they'll have 2 per and all 16 will be used.

Last week, a dairy farm produced n kg of cheese.
The dairy farm also produced 30 kg more yoghurt than cheese and 4 times
as much ice cream as cheese.
The dairy farm produced more kilograms of ice cream than yoghurt last
week.
Write and solve an inequality to work out the possible values of n.
Answer:
The dairy farm produced 30 + n kg of yoghurt, where n is the number of kilograms of cheese produced.
The dairy farm also produced 4n kg of ice cream, where n is the number of kilograms of cheese produced.
Since the dairy farm produced more kilograms of ice cream than yoghurt, we can write the following inequality:
4n > 30 + n
Subtracting n from both sides gives us:
3n > 30
Dividing both sides by 3 gives us:
n > 10
Therefore, the possible values of n are any value greater than 10, such as 11, 12, 13, 14, and so on.

Answer:

Step-by-step explanation:
z + 9 < 24
z + 9 - 9 < 24 - 9
z < 15
Answer:
z < 15
Step-by-step explanation:
To solve for z, you need to isolate it on one side of the equal sign, or in this case, the < sign.
If you subtract 9 from the left side of the equation, z will be alone. But whatever you do to one side you have to do to the other. So subtract 9 from 24 as well and you get z < 15

The exponential function that represents the population is y = a*3^x.
What is exponential function?
The formula for exponential functions is y = ab^x, where b is the constant ratio and a is the starting point. Observe that as the value of x increases by a constant amount, the value of y increases by a common ratio by looking at a table of ordered pairs. All exponential functions share this trait.
We have to find the exponential function for the given table.
Since,
Exponential function = ab^x
where,
a is the starting point
b is the common ratio.
Here,
Common ratio = 24/8 = 72/24 = 216/72 = 648/216 = 3
So, the function becomes,
Exponential function = y = a*3^x
Hence, the exponential function that represents the population is

Solve your equation using trail and improvement. A number plus ten times its square root is is equal to one thousand
Answer:
[tex]x \approx 729[/tex]
Step-by-step explanation:
Given
Let the number be x
So:
[tex]x + 10\sqrt x = 1000[/tex]
Required
Using trial and improvement, find x
This implies that we keep guessing the values of x until we get a value that match the equation.
Let
[tex]x = 625[/tex]
So, we have:
[tex]x + 10\sqrt x = 1000[/tex]
[tex]625 + 10 *\sqrt{625}[/tex]
Take the square root of 625
[tex]625 + 10 *\sqrt{625} = 625 + 10 *25[/tex]
[tex]625 + 10 *\sqrt{625} = 625 + 250[/tex]
[tex]625 + 10 *\sqrt{625} = 875[/tex]
Let
[tex]x = 729[/tex]
So, we have:
[tex]x + 10\sqrt x = 1000[/tex]
[tex]729 + 10 * \sqrt{729}[/tex]
Take the square root of 729
[tex]729 + 10 * \sqrt{729} = 729 + 10 * 27[/tex]
[tex]729 + 10 * \sqrt{729} = 729 + 270[/tex]
[tex]729 + 10 * \sqrt{729} = 999[/tex]
At this point, we can conclude that x is approximately 729 because
[tex]999 \approx 1000[/tex]

324002.4/477 to get the scale ratio. Which is 679.25:1
I am halfway through the problem and notice I should have converted mm to ft and not the other way around. It gives the same answer it just takes an extra step.
188*679.25=127699mm for one side.
Convert that back to ft and you get 418.959 which would just be 419 ft
Answer:

Step-by-step explanation:
convert ft to mm: 1063 ft ≈ 324002.4 mm (I just used g00gle)
324002.4/477 ≈ 679.25, the real Eiffel tower is ≈ 679.25 times larger
188 x 679.25 = 127699 mm
convert mm to ft: 127699 mm ≈ 418.96 ft ≈ 419 ft
