Let's use the given information to set up equations to solve for the ages of the family members.
We know that the mean age of the family is 23 years, so we can write:
(sum of ages) / 7 = 23
sum of ages = 161
We also know that the median age is 16 years, which means that the ages of the family members can be arranged in order from smallest to largest, and the middle age (or the average of the two middle ages, if there are an even number of ages) is 16. We can use this information to set up an equation:
(3rd smallest age + 4th smallest age) / 2 = 16
3rd smallest age + 4th smallest age = 32
Next, we know that the range of the ages is 35 years, which means that the difference between the largest age and the smallest age is 35. We can use this information to set up another equation:
largest age - smallest age = 35
Finally, we know that the modes (the most common ages) are 12 years and 45 years. This means that there are two family members whose ages are 12 years and two family members whose ages are 45 years. We can use this information to set up two more equations:
number of 12-year-olds + number of 45-year-olds = 4
12 x number of 12-year-olds + 45 x number of 45-year-olds = sum of ages
We now have five equations and five unknowns (the ages of the seven family members). We can solve for these unknowns using algebra. One possible set of ages that satisfies all of the equations is:
2, 2, 12, 16, 20, 45, 64
(Note that the ages do not have to be integers, but this particular set of ages happens to be integers and satisfies all of the given conditions.)

On the first day of school, Ms. Dubacek gave her third-grade students
6 new spelling words to learn. On each day of school after that, she gave the students 3 new spelling words. How many new spelling words had she given the students by the end of the 21st day of school?
Answer: 126 Spelling Words
Step-by-step explanation: I got that because you had to multiply 6 by 21 and you get 126.Answer:
Step-by-step explanation:
On the first day, Ms. Dubacek gave 6 new spelling words.
On each subsequent day, she gave an additional 3 new spelling words.
Therefore, on the second day of school, she gave a total of 6 + 3 = 9 new spelling words.
On the third day of school, she gave a total of 6 + 3 + 3 = 12 new spelling words.
We can see a pattern emerging here: on each day, she gives 6 more words than the previous day.
So on the 21st day of school, she will have given a total of:
6 + (9 + 12 + 15 + ... + 60)
To find the sum of this arithmetic series, we can use the formula:
S = n/2 * (a + l)
where:
S = the sum of the series
n = the number of terms in the series
a = the first term in the series
l = the last term in the series
In this case, we have:
n = 19 (since we're counting from the second day of school to the 21st day)
a = 9 (since that was the total number of spelling words given on the second day)
l = 60 (since that will be the total number of spelling words given on the 21st day)
So, plugging in these values, we get:
S = 19/2 * (9 + 60) = 19/2 * 69 = 655.5
Therefore, by the end of the 21st day of school, Ms. Dubacek will have given her students a total of 6 + 655.5 = 661.5 new spelling words (rounded to the nearest whole number, this is 662).

Answer:
Rectangle pyramid
What is a rectangle pyramid ?
A rectangular pyramid is a pyramid, which has a rectangular-shaped base. If we look at the bottom view of this pyramid, it looks like a rectangle. Hence, the base has two parallel sides equal.
A pyramid crowns at a point on top of the base, which is known as the apex. A rectangular pyramid can be a right pyramid or oblique pyramid. If it is a right rectangular pyramid, then the apex lies right over the center of the base and if it is an oblique rectangular pyramid, the apex is not directly over the center of the base, but at some angle from the center.
Apart from the rectangular pyramid, there are other types of pyramids based on the shape of their bases, such as:

What is the probability that at least one of a pair of fair 6-sided dice shows the number 2, given that the sum of the dice is 4?
Therefore, the probability that at least one of the dice shows the number 2, given that the sum of the dice is 4, is 1 - (1/5) = 4/5, or 0.8, which is the probability that at least one of the two dice is a 2.
What are instances and probability?It is founded on the likelihood that something will occur. The rationale for probability is the central tenet of theoretical probability. For instance, there is a 12% chance that a coin will land on its head when flipped.
There are five possible ways to obtain a sum of 4 with two 6-sided dice: {(1,3),(2,2),(3,1),(2,1),(1,2)}.
Out of these five possible outcomes, there is only one outcome where neither of the dice show a 2, which is {(1,3)}.
Therefore, the probability that at least one of the dice shows the number 2, given that the sum of the dice is 4, is 1 - (1/5) = 4/5, or 0.8, which is the probability that at least one of the two dice is a 2.

Ray is purchasing a laptop that is on sale for 25% off. He knows the function that represents the sale price of his laptop is c(p) = 0. 75p, where p is the original price of the laptop. He also knows he has to pay 8% sales tax on the laptop. The price of the laptop with tax is f(c) = 1. 08c, where c is the sale price of the laptop. Determine the composite function that can be used to calculate the final price of ray's laptop.
Answer:
the final price of Ray's laptop is 89.1% of the original price.
Step-by-step explanation:
To find the composite function that can be used to calculate the final price of Ray's laptop, we need to find the composition of the two functions given:
f(c) = 1.08c (function for calculating the price of the laptop with tax)
c(p) = 0.75p (function for calculating the sale price of the laptop)
We can find the composite function f(c(p)) by substituting c(p) into the formula for f(c):
f(c(p)) = 1.08c(p)
Substituting c(p) with 0.75p, we get:
f(c(p)) = 1.08(0.75p)
Simplifying, we get:
f(c(p)) = 0.81p
Therefore, the composite function that can be used to calculate the final price of Ray's laptop is f(c(p)) = 0.81p.
This means that to find the final price of the laptop, we need to take the original price, multiply it by 0.75 to get the sale price, and then multiply the sale price by 1.08 to add the sales tax. In other words, the final price is:
final price = f(c(p)) = 0.81p = 1.08(0.75p)
final price = 0.81p + 0.081p
final price = 0.891p
Therefore, the final price of Ray's laptop is 89.1% of the original price.

(The elevation gain shown for the Old Cabin is the elevation gained between the start of the trail and the Old Cabin.) Point of Interest Elevation gain (in ft) Old Cabin −32.78 Ruby Falls 8634 Thunder Gorge −14725 High Point Vista 346.47 What is a hiker’s elevation above sea level (in feet) upon reaching High Point Vista?
Answer:
Step-by-step explanation:
To find the hiker's elevation above sea level upon reaching High Point Vista, we need to add up the elevation gain from the start of the trail to High Point Vista. We can use the table to do this:
Elevation gain from start to Old Cabin: -32.78 ft (negative because the hiker loses elevation)
Elevation gain from Old Cabin to Ruby Falls: 8634 ft
Elevation gain from Ruby Falls to Thunder Gorge: -14725 ft (negative because the hiker loses elevation)
Elevation gain from Thunder Gorge to High Point Vista: 346.47 ft
To find the hiker's elevation above sea level at High Point Vista, we add up these elevation gains:
179 ft (start) - 32.78 ft + 8634 ft - 14725 ft + 346.47 ft = -5668.31 ft
The negative value means that the hiker is below sea level at High Point Vista, which is not possible. Therefore, there must be an error in the elevation gain listed for one of the points of interest. It's possible that the elevation gain for Ruby Falls is incorrect, as it seems unlikely that the hiker would gain more than 8000 ft in elevation between Old Cabin and Ruby Falls. Without more information, it's difficult to say for sure where the error lies.

If 10% of a number is 12 and 35%% of the same number is 42, find 25%% of that number.
42 is not the answer
Answer:25% of the number is 30
Step-by-step explanation:
Let's call the number we're looking for "x". We can use the information given in the problem to set up two equations:
10% of x is 12:
0.1x = 12
35% of x is 42:
0.35x = 42
Now we can solve for x:
0.1x = 12
x = 120
0.35x = 42
x = 120
We get the same value for x from both equations, which confirms that our solution is correct. Now that we know x = 120, we can find 25% of that number:
25% of 120 = 0.25 x 120 = 30
Therefore, 25% of the number is 30.

If your parents are buying a house for $187,500. their realized income be before each month is $5250.
How to find the realized income?Loan amount = $187,500 - (187,500 * 20%)
Loan amount = $ 150,000
Monthly rate = 4.65% / 12 = 0.3875%
Interest rate for the first month is:
Interest rate = $ 150,000 * 0.3875% = $ 581.25.
Loan repayment =$ 1,575 - $ 581.25 = $ 993.75.
Amount parents owe = $ 150,000 - $ 993.75 = $149,006.25
Second month Loan = $ 1,575 - ($149,006.25 * 0.3875%) = $ 997.60
Second month ending amount owe = ( $149,006.25 - $997.60)
Second month ending amount owe = $ 148,008.65
A monthly loan payment that is not more than 30% of monthly income will be used to find the realized income.
Realized income = $ 1,575/30% = $ 5,250
Therefore the realized income is $5250

To determine the number of sides in both envelopes combined, we add these values: 16 + 14 = 30.
Therefore, the combined number of sides in both envelopes is 30.
Step-by-step explanation:
1. Is A'B'C'D' a translation, rotation, or reflection of ABCD? Explain how you can tell. (2 points)
2. Is A"B"C"D" a translation, rotation, or reflection of A'B'C'D'? Explain. (2 points)
3. Suppose the measure of ∠B is 89°. Which other angles must measure 89°? How do you know? (3 points)
4. What is the perimeter of A"B"C"D"? Explain how you found the perimeter. (3 points)
Answer:
Step-by-step explanation: OK so is A'B'C'D' a translation, rotation, or reflection of ABCD? OK so A'B'C'D' is a rotation i believe because like you i'm on the same thing. Is A"B"C"D" a translation, rotation, or reflection of A'B'C'D'? OK so A"B"C"D" is a reflection i believe i'm not really sure on that one. Suppose the measure of angle B is 89°. Which other angle must be 89°? OK so angle A, angle C, and angle B. But I really don't get what you trying to ask? Hope I kind of helped, like i said im in 8th grade and it is kind of hard for me too.
A spinner is divided into six equal parts numbered 1, 2, 3, 4, 5, and 6. In a repeated experiment, Ryan spun the spinner twice. The theoretical probability of both spins being even numbers is 9 over 36.
If the experiment is repeated 100 times, predict the number of times both spins will be even numbers.
25
36
50
100
The number of times both spins will be even numbers is 25.
What is probability?The probability of an occurrence is a figure that represents how likely it is that the event will take place. It is represented by a number between 0 and 1.
It is given that the spinner is spun twice.
The theoretical probability of both spins being even numbers is = [tex]\frac{9}{36}[/tex]
When the experiment is repeated 100 times, the number of times both spins come out to an even number = [tex]\frac{9*100}{36}[/tex]
= [tex]25[/tex]
Therefore, the number of times both spins will be even numbers is 25.

A vehicle is running at a constant speed of 60 miles per hour on a highway. When it started, it had 10 gallons of gasoline in its cylinder. The vehicle travels 30 miles on each gallon of gasoline. Ignore the initial acceleration at the start and final deceleration when the vehicle runs out of gasoline and comes to halt. The amount of gasoline in the vehicle can be modeled as a linear function G(t)=10−2t, where t is time, in hours. How much gas is consumed in the first 3 hours?
1, 3 gallons
2, 4 gallons
3, 6 gallons
7, gallons
The quantity of gas that was consumed in the first 3 hours is; 6 gallons.
What quantity of gas is used in the first 3 hours?As evident in the task content;
Speed refers to the magnitude of the velocity or the rate distance is traversed in a given time.
the speed of the vehicle = 60 miles per hour
the quantity of gasoline = 10 gallons.
Since G (t) = 10 - 2t
When t = 3
G (3) = 10 - 2(3)
G(3) = 4 gallons
Ultimately, the quantity of gas consumed in the first 3 hours is;
10 gallons - 4 gallons
= 6 gallons.
