The ratio of boys to girls in ms. zombo's class is 33 to 22. in mr. stolarski's class it is 55 to 33. if there are 15 students in ms. zombo's class and 32 students in mr. stolarski's class, what is the ratio of boys to girls in the combined classes?
For combined classes of Ms. Zombo's and Mr. Stolarski's, the number of boys and girls are determined based on their respective ratios and total number of students. The combined ratio of boys to girls is 29:18.
Explanation:The question asks for the combined ratio of boys to girls in both Ms. Zombo's and Mr. Stolarski's classes. Firstly, identify the number of boys and girls in each class based on the given ratio and total students. In Ms.Zombo's class, the ratio of boys to girls is 33:22, and there are total 15 students. So, the number of boys is (33/(33+22))*15= 9 boys and 6 girls. Similarly, in Mr.Stolarski's class the ratio is 55:33, there are 32 students, so there are (55/(55+33))*32 =20 boys and 12 girls.
Next step is to combine the classes. The total number of boys from both classes is 9 (from Ms. Zombo's class) + 20 (from Mr.Stolarski's class) = 29 boys. The total number of girls is 6 (from Ms. Zombo's class) + 12 (from Mr.Stolarski's class) =18 girls.
Therefore, the combined ratio of boys to girls from both classes is 29:18.

Find the value of x that makes m ∥ n
Answer:
The value of x that makes m || n is x = 20
Step-by-step explanation:
Given a line that is intersected by another two lines (for example line ''m'' and line ''n'' like in the exercise) one of the conditions that makes m || n is that the alternate interior angles must be congruent. Understanding that congruent means the same.
In the exercise, one pair of alternate interior angles are (2x+20)° and 3x°.
We need this two angles to be congruent ⇒ [tex]3x=2x+20[/tex]
Solving this for ''x'' :
[tex]3x=2x+20\\3x-2x=20\\x=20[/tex]
The value of x that makes 3x° congruent to 2x+20° (that makes the alternate interior angles congruents) is x = 20
Answer:
20
Step-by-step explanation:
Theorem:
If two lines are cut by a transversal such that alternate interior angles are congruent, then the lines are parallel.
Lines m and n are cut by a transversal.
Angles 3x and 2x + 20 are alternate interior angles.
For lines m and n to be parallel, angles 3x and 2x + 20 must be congruent, so their measures must be equal.
3x = 2x + 20
x = 20
Answer: 20

What is a security deposit?
Sheila purchased ski equipment for $513 using a six-month deferred payment plan. The interest rate after the introductory period is 18.39%. A down payment of $125 is required as well as a minimum monthly payment of $65. What is the balance at the beginning of the seventh month if only the minimum payment is made during the introductory period?
$65 * 6 = $390 total monthly payments made
The downpayment made is $125, so the total balance at the end is:
balance = $513 – ($125 + $390)
balance = - $2
There is an excess of 2 dollars at the end.
Sheila's balance at the beginning of the seventh month will be approximately $393.95 after considering the deferred payment and applying the interest rate.
To determine the balance at the beginning of the seventh month, follow these steps:
Calculate the initial loan amount: Sheila purchased equipment worth $513 minus a down payment of $125, leaving a balance of $388.Introductory period payments: Over six months, Sheila makes the minimum payment of $65 each month. Therefore, total payments during the introductory period are $65 x 6 = $390.Balance at end of introductory period: Since the deferred payment plan means these monthly payments were applied directly to the purchasing price rather than reducing the balance with interest-free monthly payments, the balance remains $388.Interest application: After the introductory period, interest accrues on the balance of $388 at an annual rate of 18.39%. This translates to a monthly interest rate of 18.39% / 12 ≈ 1.5325%.Calculating the new balance: Applying one month of interest on the balance, $388 increases by 1.5325% or $388 x 0.015325 ≈ $5.95. Therefore, the balance at the beginning of the seventh month is $388 + $5.95 ≈ $393.95.So, Sheila’s balance at the beginning of the seventh month is approximately $393.95.
Which of the following statements does not describe the structure of an atom?
An atom has a small, dense center called the nucleus.
Inside the nucleus of an atom are protons and electrons.
Protons are positively charged sub-atomic particles.
Electrons are negatively charged sub-atomic particles.
Final answer:
The incorrect statement is that the nucleus of an atom contains protons and electrons; actually, the nucleus contains protons and neutrons, with electrons orbiting around it.
Explanation:
The statement that does not correctly describe the structure of an atom is 'Inside the nucleus of an atom are protons and electrons'. This statement is incorrect because the nucleus of an atom actually contains protons and neutrons, not electrons. Electrons are negatively charged sub-atomic particles that orbit around the nucleus. The nucleus itself is a small, dense center that is positively charged due to the presence of protons, which are positively charged. Neutrons, which have no electric charge, are also found within the nucleus.
Further expanding on atomic structure, the nucleus is very tiny compared to the rest of the atom, which is mostly empty space. The electrons residing in this space are in perpetual motion, creating a cloud-like region around the nucleus. Despite their small mass compared to protons and neutrons, the number of electrons equals the number of protons in a neutral atom, balancing the charge.

The cost of a classified ad is based on a daily rate plus a flat service fee. One day cost $3.50 and four days cost $800 write and solve a linear equation to find the cost of a 7-day ad.
x= 11
hope this helped :)
The linear equation that gives the cost in dollars, y, in terms of the number of days the ad appears, x is: y = $1.50x + $2.00
The cost of a 7-day ad is $12.50.
Let, the daily rate is "d" dollars and the flat service fee is "f" dollars.
We are given two pieces of information:
One day costs $3.50.
Four days cost $8.00.
Using this information, we can set up two equations:
For one day: d + f = $3.50
For four days: 4d + f = $8.00
Now, we need to solve this system of linear equations to find the values of "d" and "f."
Subtract Equation 1 from Equation 2 to eliminate "f":
(4d + f) - (d + f) = $8.00 - $3.50
3d = $4.50
Now, divide both sides by 3 to solve for "d":
d = $4.50 / 3
d = $1.50
Now that we have the value of "d," we can find the value of "f" by substituting "d" into Equation 1:
d + f = $3.50
$1.50 + f = $3.50
Now, subtract $1.50 from both sides to solve for "f":
f = $3.50 - $1.50
f = $2.00
So, the daily rate (d) is $1.50, and the flat service fee (f) is $2.00.
We get, a linear equation that gives the cost in dollars, y, in terms of the number of days the ad appears, x is: y = $1.50x + $2.00
Now, to find the cost of a 7-day ad, we can use the daily rate and multiply it by the number of days (7):
Cost of a 7-day ad = 7 * $1.50 + $2.00
Cost of a 7-day ad = $10.50+ $2.00 = $12.50
The cost of a 7-day ad is $12.50.

Part C: Alligators and crocodiles equal: Solve [tex]\(20 \times (1 + 0.25)^t = 25 + 10t\).[/tex]
Part A:
Let's define the functions to represent the number of alligators and crocodiles in the swamp over the years.
For alligators:
[tex]\[A(t) = A_0 \times (1 + r)^t\][/tex]
Where:
[tex]- \(A(t)\) is the number of alligators in the swamp after \(t\) years.\\- \(A_0\) is the initial number of alligators (20 in this case).\\- \(r\) is the growth rate per year (25% or 0.25).\\- \(t\) is the number of years.[/tex]
For crocodiles:
[tex]\[C(t) = C_0 + n \times t\][/tex]
Where:
[tex]- \(C(t)\) is the number of crocodiles in the swamp after \(t\) years.\\- \(C_0\) is the initial number of crocodiles (25 in this case).\\- \(n\) is the number of new crocodiles joining each year (10 in this case).\\- \(t\) is the number of years.[/tex]
Part B:
To find the number of alligators after 4 years, we use the formula:
[tex]\[A(4) = 20 \times (1 + 0.25)^4\][/tex]
To find the number of crocodiles after 4 years, we use the formula:
[tex]\[C(4) = 25 + 10 \times 4\][/tex]
Part C:
To find when the number of alligators and crocodiles are the same, we set [tex]\(A(t) = C(t)\) and solve for \(t\).[/tex]
[tex]\[20 \times (1 + 0.25)^t = 25 + 10 \times t\][/tex]
This equation can be solved numerically to find the value of \(t\) when the number of alligators and crocodiles are the same.
