(the three numbers is the same number)
Answer:
The numbers are -14,-13 and -12
Step-by-step explanation:
The correct question is
Find three consecutive integers such that the sum of the first, twice the second and three times the third is -76. What is the number?
Let
x ----> the first consecutive integer
x+1 ---> the second consecutive integer
x+2 ---> the third consecutive integer
we have that
[tex]x+2(x+1)+3(x+2)=-76[/tex]
solve for x
apply distributive property
[tex]x+2x+2+3x+6=-76[/tex]
Combine like terms
[tex]6x+8=-76[/tex]
subtract 8 both sides
[tex]6x=-76-8[/tex]
[tex]6x=-84[/tex]
Divide by 6 both sides
[tex]x=-14[/tex]
so
[tex]x+1=-14+1=-13[/tex]
[tex]x+2=-14+2=-12[/tex]
therefore
The numbers are -14,-13 and -12

Hope this helps :) -Zach
Step-by-step explanation:
To determine the fraction of total interest owed on a loan after the fifth month of a 12-month loan, calculate the numerator by adding the interest paid in each of the first five months, and the denominator by summing the interest amounts for all twelve months. Divide the numerator by the denominator to get the fraction (to the nearest tenth).
Explanation:To determine the fraction of total interest paid after the fifth month of a 12-month loan, we can use the Rule of 78. This rule states that the majority of the interest on a loan is paid in the early months of the term.
The formula for the Rule of 78 is:
(n + 5)(n + 4)(n + 3)(n + 2)(n + 1) / (n × (n + 1) × (n + 2) × (n + 3) × (n + 4))
where 'n' represents the number of payments remaining.
In this case, we have 7 payments remaining after the fifth month. Plugging this value into the formula, we get:
(7 + 5)(7 + 4)(7 + 3)(7 + 2)(7 + 1) / (7 × (7 + 1) × (7 + 2) × (7 + 3) × (7 + 4)) = 0.505
Therefore, after the fifth month of a 12-month loan, approximately 50.5% of the total interest has been paid.

Rashid has been purchasing bonds from a company that has recently gotten poor ratings for its ability to pay Its vendors. As a resu
Increased risk, the bond's interest rate has increased. What type of risk does Rashid face as an Investor?
A
taxability risk
• B.
Inflationary risk
C.
currency risk
D.
credit risk
Answer:
The answer is letter D, credit risk.
Step-by-step explanation:
A bond is considered to be a contract between two occurring parties. It allows companies to borrow money from people (investors). These investors purchase the bond and are given a certain interest for a particular period of time. The rate varies according to the economic situation or the company's standing. This affects the supply and demand for the bond.
Remember that the price of the bond and the interest rate are indirectly proportional. This means that as the price of the bond increases, the interest rate decreases and vice-versa.
In the situation above, Rashid is facing a credit risk as an investor. He has been purchasing bonds from a company that has recently gotten a poor rating. This means that the company is not performing well. This can affect the amount of money (including the interest) that will be paid back to Rashid. There is a chance that some of the amount of money he invested will not be returned to him. It was also mentioned that the bond's interest rate has increased. This means that the bond prices will decrease and thus the number of bond investors will also decrease. The issuer of the bond in this situation can have a hard time paying the investor back.

Karachi earns $5 for each umbrella that he
sells and $3.50 for each rain poncho that he
sells. He earned $190 last week selling
ponchos and umbrellas.
Write an equation to represent the number
of umbrellas (u) and ponchos (p) he sold last
week.
The equation to represent the number of umbrellas (u) and ponchos (p) he sold last week is 5u + 3.5p = 190
Solution:
Given that Karachi earns $5 for each umbrella that he sells and $3.50 for each rain poncho that he sells
Thus we can say,
Amount earned from 1 umbrella = $ 5
Amount earned from 1 rain poncho = $ 3.50
To find: equation to represent the number of umbrellas (u) and ponchos (p) he sold last week.
Let "u" be the number of umbrellas sold
Let "p" be the number of ponchos sold
He earned $190 last week selling ponchos and umbrellas
Thus we can frame a equation as,
number of umbrellas sold x Amount earned from 1 umbrella + number of ponchos sold x Amount earned from 1 rain poncho = $ 190
[tex]u \times 5 + p \times 3.50 = 190\\\\5u + 3.5p = 190[/tex]
Thus the equation to represent the number of umbrellas (u) and ponchos (p) he sold last week is found
To represent the number of umbrellas (u) and ponchos (p) sold by Karachi last week, the equation is 5u + 3.50p = 190.
Explanation:To represent the number of umbrellas (u) and ponchos (p) sold by Karachi last week, we can set up an equation based on the given information:
5u + 3.50p = 190
This equation represents the earnings from selling umbrellas (at $5 each) and rain ponchos (at $3.50 each) totaling $190. We can use this equation to find the values of u and p.

jamal's age is 3 more than 3 times Mike's age. Mike's age is 17 years less than Jamals agee. What is the sum of the ages of Mike and Jamal?
Jamal's age is 24
Mikes age is 7
so their ages together would equal 31
Answer:
The sum of the ages of Mike and Jamal is 31
Step-by-step explanation:
First we need to translate the questions into mathematical equation and then solve.
Let x be Jamal's age and y be Mike's age.
"Jamal's age is 3 more than 3 times Mike's age" can be written mathematically as;
x =3 + 3y ---------------------------------------------------------------(1)
"Mike's age is 17 years less than Jamal's age" can be written mathematically as ;
y = x - 17 -----------------------------------------------------------------(2)
Substitute equation (1) into equation (2)
y = 3 + 3y - 17
y = 3y - 14
subtract 3y from both-side of the equation
y - 3y = 3y - 3y - 14
-2y = -14
Divide both-side of the equation by -2
[tex]\frac{-2y}{-2}[/tex] = [tex]\frac{-14}{-2}[/tex]
y = 7
Mike is 7 years old
Substitute y = 7 into equation (1)
x = 3 + 3y
= 3 + 3(7)
= 3+21
=24
Jamal is 24 years old
The sum of their ages is = x + y = 24 + 7 = 31
Therefore, The sum of the ages of Mike and Jamal is 31

Astronaut that weighs 180 pounds at what distance from the center earth the astronaut weigh 1 pound.
Answer:
The height of the astronaut from the center of the Earth is 85865 km.
Step-by-step explanation:
It is assumed that the astronaut will be going towards space, so we have to find out that at what height from the center of the earth would the value of g will be [tex]\frac{g}{180}[/tex].
The weight of astronaut on the surface of Earth 180 pounds.
g=9.81 [tex]m/s^{2}[/tex]
Required value of g'=[tex]\frac{g}{180}[/tex]
g'=[tex]\frac{gR^{2} }{h^{2} }[/tex]
where R=Radius of the Earth
h=Height of the point from the center of the earth
[tex]\frac{g}{180} = \frac{gR^{2} }{h^{2} } \\\\h^{2} =180R^{2} \\h=\sqrt{180} R\\[/tex]
h=13.42
The value of R is approximately 6400 km.
So, h=85865 km.
The astronaut would need to be approximately 85,552 kilometers from the center of the Earth to weigh 1 pound.
Newton's law of universal gravitation is given by the formula:
[tex]F = G \frac{m_1 m_2}{r^2}[/tex]
Where:
[tex]F[/tex] is the gravitational force,[tex]G[/tex] is the gravitational constant [tex](6.674 \times 10^{-11} \text{Nm}^2/\text{kg}^2)[/tex],[tex]m_1[/tex] is the mass of the first object (the astronaut),[tex]m_2[/tex] is the mass of the second object (Earth),[tex]r[/tex] is the distance between the centers of the two objects.On Earth's surface, the weight of the astronaut is the gravitational force exerted by the Earth. This can also be expressed as:
[tex]Weight = m_1 \cdot g[/tex]
Where [tex]g[/tex] is the acceleration due to gravity (approximately [tex]9.8 \text{m/s}^2[/tex]).
Given that the astronaut weighs 180 pounds on Earth, we use the following relation to find the new distance where the astronaut's weight would be 1 pound:
[tex]180 \text{ pounds} \div r^2 = 1 \text{ pound}[/tex]
[tex]r^2 = 180[/tex]
[tex]r = \sqrt{180}[/tex]
However, we need this distance in terms of the Earth's radius [tex]( R_E )[/tex]. The Earth's radius is approximately 6,371 km.
Let's form the ratio:
[tex]\left( \frac{d}{R_E} \right)^2 = 180[/tex]
[tex]\frac{d}{R_E} = \sqrt{180} \approx 13.42[/tex]
Thus, the astronaut would need to be approximately 13.42 times the Earth's radius away from the center of the Earth to weigh 1 pound.
To convert this to an actual distance:
[tex]d = 13.42 \cdot R_E[/tex]
[tex]d \approx 13.42 \cdot 6371 \text{ km} \approx 85,552 \text{ km}[/tex]
Decide whether the two events are disjoint and tell why or why not:
• randomly drawing a jack from a standard deck of cards
• randomly drawing an ace from a standard deck of cards
Disjoint, because the events can occur at the same time.
Not disjoint, because the events can occur at the same time.
Not disjoint, because the events cannot occur at the same time.
Disjoint, because the events cannot occur at the same time.
Answer:
Disjoint, because the events cannot occur at the same time.
Step-by-step explanation:
disjoint events are mutually exclusive events.
if a and b are two events then a intersection b will be 0 . they cannot occur at the same time.
here in the given problem let the event A be randomly drawing a jack from a standard deckn of card and evnt B be randomly drawing an ace from a standard deck of card.
since in a same card jack and ace cannot occur they are disjoint events.
therefore randomly drawing a jack from a standard deck of cards and randomly drawing an ace from a standard deck of cards are disjoint events because the events cannot occur at the same time.
The two events are disjoint because a card from a standard deck cannot be both a jack and an ace at the same time. That is, these events cannot occur simultaneously.
Explanation:In the given scenario, the two events - randomly drawing a jack from a standard deck of cards and randomly drawing an ace from a standard deck of cards - are disjoint. This is because these are separate and distinct events which cannot occur simultaneously. In terms of probability theory, two events are considered disjoint if the occurrence of one event excludes the possibility of the occurrence of the other event. In a standard deck of cards, a card cannot be both a jack and an ace at the same time.

Percentage of adults who felt fully engaged with their mortgage provider: 22%
Confidence level: 95%
1. Population: All adults who have a mortgage provider.
2. Sample size: 1,627 adults.
3. Margin of error:
To calculate the margin error,
The sample size (n) and the confidence level.
Given that, the confidence level = 95%,
The margin error can be calculated using the formula:
The Margin of Error [tex]= Z \sqrt{(p (1-p) / n)}[/tex]
Assume a conservative estimation for p = 0.5 (since we don't have the sample proportion), and using a Z-value of 1.96 for a 95% confidence level,
The margin error would be:
The margin of error is,
[tex]1.96\sqrt{(0.5 (1-0.5) / 1627)} \approx 0.02[/tex]
Therefore, the 95% margin error is approximately 0.02.
4. 95% Confidence Interval:
Without the sample proportion, we cannot provide a specific confidence interval.
Assume a conservative estimate of p = 0.5,
Calculate the interval using the formula:
Confidence Interval = Sample Proportion ± Margin of Error
Given that,
The sample proportion is 0.22
The margin error is 0.016,
The 95% of the confidence interval is,
0.22 ± 0.016 = 0.24 or 0.2

A diagram of a concrete patio is shown, where each small square represents one square meter. Find the total area of the concrete patio.
Answer:
C
Step-by-step explanation:
The red bordered area is the patio. We need to find its area.
We will consider
If this was a square, full red square. Then we find the area of the square.
After that, we will subtract the white part that is not there to create the patio shape.
Hence,
Area of Patio = Area of Square - Area of White Portion
So,
Area of Square is Side * Side
If we look at the coordinates, x goes from 5 to 15, so side is 15 - 5 = 10
also, y goes from 5 to 15, so same, that is 10
Area of Square = 10 * 10 = 100
Now, the small white portion is also a square with length 5 (looking at coordinates),
So,
Area of White Portion = 5 * 5 = 25
Hence,
Area of Patio = 100 - 25 = 75 sq. meters
Correct answer is C
How can you use the point-slope form of a line when only given two points?
Answer:
If we already have two points of the line, we can find its slope ([tex]m[/tex]), its intersection with the y-axis ([tex]b[/tex]), hence its point-slope form equation in the following way:
Let's call Point 1: [tex](x_{1},y_{1})[/tex] and Point 2: [tex](x_{2},y_{2})[/tex]
The Slope equation is:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Now, the equation of the line in its point-slope form is:
[tex]y=mx+b[/tex]
And we can find the intersection with the y-axis ([tex]b[/tex]) by evaluating the equation with any of the two given points and then isolating [tex]b[/tex].
The perimeter of a rectangle is 74 cm. The length of a rectangle is 5cm less than twice the width. Find the dimensions of the rectangle.
The width of the rectangle is 14 cm and the length is 23 cm.
Explanation:Let's assume the width of the rectangle is x cm. According to the question, the length is 5 cm less than twice the width, so the length would be 2x - 5 cm. The perimeter of a rectangle is calculated by adding up the lengths of all its sides. In this case, the perimeter is given as 74 cm, so the equation becomes:
2(x + 2x - 5) = 74
Simplifying the equation, we get:
6x - 10 = 74
Adding 10 to both sides:
6x = 84
Dividing both sides by 6:
x = 14
So the width of the rectangle is 14 cm, and the length is 2(14) - 5 = 23 cm.

Answer:
f(6) = - 4 is incorrect.
Step-by-step explanation:
In the given table the values of x and corresponding values of f(x) are given.
The ordered pairs are (-4,6), (-2,3), (0,-1) and (2,-4).
Now, we have to determine the function y = f(x) from any two of the given ordered pair.
The equation of the function is
[tex]\frac{y - 6}{6 - 3} = \frac{x - (- 4)}{- 4 - (- 2)}[/tex]
⇒ -2(y - 6) = 3(x + 4)
⇒ 2y + 3x = 0 ........... (1)
Now, putting x = 6 in the above equation (1), we get y = - 9
Therefore, f(6) = - 9
Hence, f(6) = - 4 is incorrect. (Answer)
