Answer:
p - 3000 = 16000
Step-by-step explanation:
none of the options given are correct
The correct equation representing the situation is p - 3000 = 16000, where p is the original price of the car.The correct answer is option D
To determine the correct equation that describes the given situation, we need to understand the relationship between the original price of the car and its discounted price.
Let p represent the original price of the car.
The problem states that the original price was reduced by $3,000, resulting in a discounted price of $16,000.
This relationship can be represented by the equation:
p - 3000 = 16000
Rearranging this equation, we find:
p = 16000 + 3000
Therefore, the best equation that represents the situation is:
p - 3000 = 16000
The correct answer is option D
Prince is 6n years old. jordan is (3n + 10) years older than prince
a) find jordans age
b) find the total age of prince and jordan
c) kimberly is 9 yrs younger than prince. find kimberlys age
d) find the total age of three people
e) if n = 4 find the total age of the 3 people
Answer:
a) 9n + 10 years.
b) 13n + 10 years.
c) 6n - 9 years
d) 19n + 1 years.
e) 77 years.
Step-by-step explanation:
a) Prince is 6n years old. Jordan's age is (3n + 10) years more than Prince.
So, Jordan's age is (6n + 3n + 10) = 9n + 10 years.
b) The total age of Prince and Jordan will be (6n + 9n + 10) = 13n + 10 years.
c) Kimberly's age is 9 years less than Prince.
So, the age of Kimberly will be 6n - 9 years.
d) The total age of the three people will be (6n - 9 + 13n + 10) = 19n + 1 years.
e) If n = 4, then total age of three people will be 19(4) + 1 = 77 years. (Answer)
a developer wants to develop 5 acres of land. Each lot in the develope is to be 1/12 of an acre. How many lots will the land developer have in the 5 acres?
Final answer:
The land developer can create 60 lots of 1/12 acre each from a 5-acre parcel of land.
Explanation:
The student's question asks how many lots of 1/12 acre each can be created from a 5-acre parcel of land. To find the answer, divide the total acres available (5 acres) by the size of each lot (1/12 acre). Using division for fractions, we invert the divisor and multiply:
5 ÷ (1/12) = 5 × (12/1) = 60
Therefore, the land developer will be able to create 60 lots from the 5 acres.
An angle measures 18 more than the angle of its complementary what is the measure of each angle
Answer:
71
Step-by-step explanation:
Complementary angles have measures that add to 90°.
ABC and CBD are complementary angles.
Since the angles are complementary, their measures must add to 90°. Set up an equation and solve for n.
n + 18° = 90°
n + 18° − 18° = 90° − 18°
n = 72°
The measure of the complementary angle is 72°.

Sharmaine works 30 hours at an exclusive restaurant. She earns
$3.50 per hour plus tips. In one week, she earned $1,250.00 in tips. What was Sharmaine’s total income?
Answer:
Sharmaine had an income of US$ 1,355 that week.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Hours per week Sharmaine works at an exclusive restaurant = 30
Salary of Sharmaine = US$ 3.50 per hour + tips
Tips of the week = US$ 1,250
2. What was Sharmaine’s total income?
Total income = Tips + Rate per hour
Total income = 1,250 + (3.5 * 30)
Total income = 1,250 + 105
Total income = 1,355
Sharmaine earned $105.00 from her hourly job and $1,250.00 in tips, making her total income $1,355.00 for the week.
Explanation:The student asked about Sharmaine's total income for a week. Sharmaine earns an hourly wage plus tips at a restaurant. To calculate her total income, we need to add her earnings from her hourly rate to her earnings from tips.
First, we determine her earnings from her hourly wage. She works 30 hours at $3.50 per hour. So, her income from her hourly wage is 30 hours × $3.50/hour = $105.00.
Next, we add her earnings from tips. Sharmaine earned $1,250.00 in tips for the week.
Her total income for the week is her hourly earnings plus her tips: $105.00 (hourly earnings) + $1,250.00 (tips) = $1,355.00.
Therefore, Sharmaine's total income for that week is $1,355.00.

Name two number that are not integers but that are opposite. Explain how you know
Answer:
Decimals, fractions and mixed units are not integers.
Step-by-step explanation:
Final answer:
Opposite non-integer numbers are pairs like 1/2 and -1/2 or 3.5 and -3.5. These pairs are not integers due to their fractional parts, yet they add up to zero, confirming they are opposites.
Explanation:
When we refer to numbers that are not integers but are opposites, we are seeking pairs of numbers whose sum is zero. Integers are whole numbers such as -1, 0, and 1, which do not include fractions or decimals. On the other hand, rational numbers are ratios of integers like 2/1 or 3/4, and these can be non-integers.
Consider the rational numbers 1/2 and -1/2; these are opposite numbers because they add up to zero. Similarly, another pair could be 3.5 (which is the same as 7/2) and -3.5 (or -7/2). These numbers are not integers because they have fractional parts, yet they are opposites because their sum is zero.
In both cases, these pairs demonstrate the mathematical property that when a number is added to its opposite, the result is always zero, which is a fundamental aspect of additive inverses. This is how we can verify that 1/2 and -1/2, as well as 3.5 and -3.5, are non-integer opposites.

A shoreline is eroding at rate of 2 5/18 feet each year at this rate,how many feet will the shoreline erode in 8 years
The shoreline will erode approximately 22 7/9 feet in 8 years.
Explanation:To find the total erosion over 8 years, we can use the given rate of erosion per year. The rate is 2 5/18 feet each year, and to calculate the total erosion over 8 years, we can multiply this rate by the number of years.
[tex]\[ \text{Rate of erosion per year} = 2 \frac{5}{18} \text{ feet} \][/tex]
[tex]\[ \text{Total erosion over 8 years} = \text{Rate of erosion per year} \times \text{Number of years} \][/tex]
[tex]\[ \text{Total erosion} = 2 \frac{5}{18} \times 8 \][/tex]
To perform this calculation, first convert the mixed number into an improper fraction:
[tex]\[ \text{Total erosion} = \frac{41}{18} \times 8 \][/tex]
Multiply the numerators and denominators:
[tex]\[ \text{Total erosion} = \frac{328}{18} \][/tex]
Now, simplify the fraction:
[tex]\[ \text{Total erosion} = 18 \frac{2}{18} \][/tex]
Thus, the shoreline will erode approximately[tex]\(18 \frac{2}{18}\) feet in 8 years, which simplifies to \(18 \frac{1}{9}\) or \(22 \frac{7}{9}\) feet.[/tex]

Answer:
Hey, Dalilah. I hope I'm not too late, but the answer is (3,5).
Step-by-step explanation:
You have to use the equation that includes the x value of 3.
4x+1 only includes x values that are less than 3.
2x-1 includes x values that are greater than or equal to 3.
I plugged 3 into both of these equations (4x+1; x < 3 & 2x-1; x ≥ 3) in order to see which equation would've been true.
4(3)+1 = 13; 13 < 3 [False] 13 isn't less than 3 -- and 2(3)-1 = 5; 5 ≥ 3 [True] 5 is greater than or equal to 3.
Since the equation 2(3)-1; 5≥3 is true, you should use this equation. I used Demos in order to graph Y=2(3)-1. At the bottom of that I put x=3, and it showed me (3,5).

The statement is not reversible.
A reversible statement is one where the implication goes both ways. In simpler terms, if the statement is true, its converse (reversing the hypothesis and conclusion) must also be true, and vice versa.
The statement is: "If (x=3) then (x²=9)". The converse, "If (x² = 9) then (x = 3)" is not always true. For example, if x = -3, then x² is also 9.
A biconditional statement is true if and only if both the statement and its converse are true. Because the converse of the original statement is not always true, the biconditional statement " (x = 3) if and only if (x² = 9)" is also not true.
Julie and her brother go to Atlanta to ride the SkyView Ferris wheel. It measures 200 feet in diameter.
A)I want to know the distance around the Ferris Wheel. Would I use Circumference or Area?
B)What is the formula needed to solve this problem?Look in your notes!
C)What is the distance traveled in one rotation? Explain how you used the formula to solve the problem.
The distance around the wheel is 628 feet and distance traveled in one rotation is equal to 628 feet
Solution:
Julie and her brother go to Atlanta to ride the SkyView Ferris wheel.
It measures 200 feet in diameter
Diameter = 200 feet
We know that diameter is twice of radius
[tex]diameter = 2 \times radius\\\\200 = 2 \times radius\\\\radius = \frac{200}{2}\\\\radius = 100[/tex]
Thus radius of wheel is 100 feet
The distance around the ferris wheel is the circumference of wheel
Since, wheel is of circular shape, we can use circumference of circle formula
The circumference of circle is given as:
[tex]C = 2 \pi r[/tex]
Where "r" is the radius and [tex]\pi[/tex] is a constant equal to 3.14
Substitute r = 100 we get,
[tex]C = 2 \times 3.14 \times 100 = 628[/tex]
Thus distance around the wheel is 628 feet
Distance traveled in one rotation = circumference of wheel
The distance traveled in one rotation is equal to 628 feet
The stadium has a form of a rectangle with two semicircles attached to the short sides. The long side of a rectangle is 2 times longer than the short one. Construct the expression for the area of the stadium in terms of x, where x denotes a shorter side of the rectangle
Answer: [tex]2x^2+\frac{\pi x^2}{4}[/tex]
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:
[tex]A_r=lw[/tex]
Where "l" is the lenght and "w" is the width.
The area of a semi-circle can be found with this formula:
[tex]A_{sc}=\frac{\pi r^2}{2}[/tex]
Where "r" is the radius.
Let be "x" the shorter side of the rectangle (which is also the diameter of the semi-circle).
Based on the information given in the exercise, you know that:
[tex]w=x\\\\l=2x[/tex]
Since the radius is half the diameter:
[tex]r=\frac{x}{2}[/tex]
Observe the figure attached, which shows the stadium.
The area of the stadium is the sum of the areas of the semi-cirlcles and the rectangle.
Therefore, you can construct the following expression for the area of the stadium is terms of "x":
[tex](2x)(x)+\frac{\pi (\frac{x}{2})^2}{2}+\frac{\pi (\frac{x}{2})^2}{2}[/tex]
Simplifying it, you get:
[tex](2x)(x)+\frac{\frac{\pi x^2}{4}}{2}+\frac{\frac{\pi x^2}{4}}{2}=2x^2+\frac{\pi x^2}{4}[/tex]
The expression for the area of the stadium in terms of x is 2x^2 + πx^2/4.
Explanation:The area of the stadium can be calculated by first finding the area of the rectangle and then adding the areas of the two semicircles. The long side of the rectangle is 2 times longer than the short side, so the dimensions of the rectangle are x for the short side and 2x for the long side. Therefore, the area of the rectangle is A = x * 2x = 2x^2. The formula for the area of a semicircle is A = πr^2/2, where r is the radius of the semicircle. In this case, the radius is x/2 since it is half of the short side of the rectangle. So, the area of one semicircle is π(x/2)^2/2 = πx^2/8. Since there are two semicircles, the total area of the semicircles is 2 * (πx^2/8) = πx^2/4.
Adding the area of the rectangle and the area of the semicircles, we get the expression for the total area of the stadium: A = 2x^2 + πx^2/4.

sasha cuts four idenetical circles from a square piece of black poster board as shown what is the left over board use 3.14 for pi
Answer:
therefore the left over board is 0.216[tex]a^{2}[/tex] where 'a' is length of a side of the black poster board.
Step-by-step explanation:
i) Sasha cuts 4 identical circles from a square piece of black poster.
ii) let each side of the square piece be a.
iii) let us divide the square piece into four equal square parts from which the four identical circles will be cut
iv) therefore the side of each smaller square will be [tex]\frac{a}{2}[/tex].
v) therefore the diameter of each identical circle will be [tex]\frac{a}{2}[/tex]
vi) therefore the radius if each of the four identical circles will be [tex]\frac{1}{2} \times \frac{a}{2} = \frac{a}{4}[/tex]
vii) the area of each of the four identical circles will be = [tex]\pi \times (\frac{a}{4} )^{2} = 3.14 \times (\frac{a}{4}) ^{2} = \frac{3.14a^{2}}{16} = 0.196a^{2}[/tex]
vii) the area of each of the four smaller squares = [tex]\frac{a}{2} \times \frac{a}{2} = \frac{a^{2} }{4} = 0.25a^{2}[/tex]
viii) therefore the area left over from each of the four smaller squares
= 0.25[tex]a^{2}[/tex] - [tex]0.196a^{2}[/tex] = 0.054[tex]a^{2}[/tex]
ix) therefore the left over board is given by 4 [tex]\times[/tex] 0.054[tex]a^{2}[/tex] = 0.216[tex]a^{2}[/tex] where a is length of a side of the black poster board.
6.50 is 25% of what number?
Answer:
26
Step-by-step explanation:
25% is 1/4 so 6.50+6.5+6.50+6.50= 26
Answer: 26
Step-by-step explanation: Reading through the problem we have "6.50 is" that's 6.50 =, "25%" 25/100, "of" times, "what number" x.
I changed 25% to 25/100 because "percent" means over 100.
Reducing the 25/100 to 1/4, we have 6.50 = [tex]\frac{1x}{4}[/tex].
Multiplying both sides by 4 to get rid of the fraction, we have 26 = x.
So 6.50 is 25% of 26.
