The quotient of -18 and the sum of -2 and d: - 18 / (d - 2)

answer

  - 18
---------
  d - 2
Answer 2
Final answer:

The quotient of -18 and the sum of -2 and d can be represented mathematically as -18 ÷ (d - 2), where we subtract 2 from d and then divide -18 by that result.

Explanation:

The quotient of -18 and the sum of -2 and d refers to dividing -18 by the result of adding -2 to d (which we can represent as d - 2 because adding a negative number is equivalent to subtracting). Mathematically, we can express this as -18 ÷ (d - 2).

To perform this operation, we first need to know the value of d. Once we have that, we subtract 2 from it, and then divide -18 by that result.

For example, if d was 4, we would perform the operation as follows:  4 - 2 gives us 2, then -18 ÷ 2 gives us -9. So, the quotient of -18 and the sum of -2 and 4 (d being 4) is -9.

Twice the number n is no less than 10 units from -1

Answers

Final answer:

The mathematical equation 'Twice the number n is no less than 10 units from -1' can be solved as two inequalities, yielding a solution of n ≤ -5.5 or n >= 4.5.

Explanation:

This is a math problem asking about the absolute value inequality of an equation. The question states 'Twice the number n is no less than 10 units from -1'. This can be written as |2n + 1| >= 10. To solve it, we'll divide it into two inequalities: 2n + 1 >= 10 and -2n - 1 >= 10. Solving the first inequality yields n >= 4.5, and solving the second inequality yields n <= -5.5. Thus, the solution to the equation is n ≤ -5.5 or n >= 4.5.

The measure of the vertex angle in an isosceles triangle is six less than four time the measure of the base angle. find the measure of the vertex angle

Answers

An isosceles triangle is a special type of triangle that has two equal sides. Consequently, the two base angles are also equal. Since the interior angles of a triangle should sum up to 180°, the general equation should be

180° = 2*Base angle + Vertex angle

Let the base angle be x. Thus, the vertex angle is equal to
Vertex angle = 4x - 6
Substituting,
180 = 2x + 4x - 6
x = 31°

Vertex angle = 4(31°) - 6 
Vertex angle = 118°

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

12-17x —————— • 4x = 0 • 4x 4x

Now, on the left hand side, the  4x  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :
   12-17x  = 0

Solving a Single Variable Equation :

 9.2      Solve  :    -17x+12 = 0 

 Subtract  12  from both sides of the equation : 
                      -17x = -12 
Multiply both sides of the equation by (-1) :  17x = 12 


Divide both sides of the equation by 17:
                     x = 12/17 = 0.706 

One solution was found :                   x = 12/17 = 0.706

The inequality 5x-(x+2)>-5(1+x)+3 simplifies to x>5/9 after combining like terms and isolating x. Therefore, any x greater than 5/9 is a solution, including x=1, which satisfies the inequality.

To find a particular solution to the inequality 5x-(x+2)>-5(1+x)+3, we first simplify both sides of the inequality:

5x - x - 2 > -5 - 5x + 3

This further simplifies to:

4x - 2 > -5x + 3

Next, we add 5x to both sides and add 2 to both sides to get:

9x > 5

Now, we divide both sides by 9 to isolate x:

x >  5/9

Therefore, any x greater than 5/9 is a particular solution to the original inequality. For example, x=1 is such a solution, as it satisfies the inequality:

5(1) - ((1)+2) > -5(1+(1)) + 3

That simplifies to:

5 - 3 > -5(2) + 3

2 > -10 + 3

2 > -7, which is true, thus confirming x=1 is a solution.

first, we find the x term...and since (1,3.5) is the midpoint, our x term has to be set equal to 1 (the x coordinate in the midpoint)
(6 + x) / 2 = 1
6 + x = 1 * 2
6 + x = 2
x = 2 - 6
x = -4
now, we find y...and since (1,3.5) is the midpoint, our y term has to be set equal to 3.5
(-2 + y) / 2 = 3.5
-2 + y = 3.5 * 2
-2 + y = 7

ABCD is a rectangle. The length of BD is 8 units, and m angle ABD is 67°. The length of AC is units, and m angle CDB is °.

Answers

The length of AC is 8 units The angle CDB is 67° Since ABCD is a rectangle, that means that all of the angles are 90 degrees and that line segment AB is parallel to line segment CD. The line segment BD is a diagonal of the rectangle. The line segment AC is also a diagonal of the rectangle so it has the same length as given for segment BD which is 8. The angle ABD is the angle between the horizontal line and the diagonal. The angle CDB is also the angle between a horizontal line and the diagonal. So it also has the same measurement so it too is 67°.

On a town map, each unit of the coordinate plane represents 1 mile. three branches of a bank are located at a(−3, 1), b(2, 4), and c(4, −2). a bank employee drives from branch a to branch b and then drives halfway to branch c before getting stuck in traffic. what is the minimum total distance the employee may have driven before getting stuck in traffic? round to the nearest tenth of a mile if necessary. answer

Answers

To compute for distance from a to b:

 

Distance A = 4 miles, base of triangle formed between a and b

 

Distance B = 3 miles, height of triangle formed between a and b

 

Distance AB = (A^2 + B^2)^0.5    hypotenuse of triangle formed between a and b, or square root of (A^2 + B^2)

 

Distance AB = ((4)^2 + (3)^2)^0.5

 

Distance AB = (16 + 9)^0.5

 

Distance AB = (25)^0.5

 

Distance AB = 5 miles

 

To compute for distance from b to where bank employee got stuck

 

BC = distance from b to c

 

BC  = 4 miles

 

Total distance driven by bank employee

 

= AB + 0.5(BC)

 

= 5 + 0.5(4)

 

= 5 + 2

 

= 7 miles, total distance driven by the bank employee

Answer:

The minimum total distance the employee may have driven before getting stuck in traffic is 9.0 miles.

Step-by-step explanation:

Given information: a(−3, 1), b(2, 4), and c(4, −2).

On a town map, each unit of the coordinate plane represents 1 mile.

Distance formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between bank a and bank b is

[tex]ab=\sqrt{(2-(-3))^2+(4-1)^2}[/tex]

[tex]ab=\sqrt{(5))^2+(3)^2}[/tex]

[tex]ab=\sqrt{25+9}[/tex]

[tex]ab=\sqrt{34}[/tex]

Distance between bank b and bank c is

[tex]bc=\sqrt{(4-2)^2+(-2-4)^2}[/tex]

[tex]bc=\sqrt{(2)^2+(-6)^2}[/tex]

[tex]bc=\sqrt{4+36}[/tex]

[tex]bc=\sqrt{40}[/tex]

[tex]bc=2\sqrt{10}[/tex]

A bank employee drives from branch a to branch b and then drives halfway to branch c before getting stuck in traffic. It means total distance employee may have driven before getting stuck in traffic is

[tex]Distance=ab+\frac{1}{2}bc[/tex]

[tex]Distance=\sqrt{34}+\frac{1}{2}(2\sqrt{10})[/tex]

[tex]Distance=\sqrt{34}+\sqrt{10}[/tex]

[tex]Distance=8.99323[/tex]

[tex]Distance\approx 9.0[/tex]

Therefore the minimum total distance the employee may have driven before getting stuck in traffic is 9.0 miles.

5)Katie is 2 years younger than her brother. In 12 years, her brother will be twice as old as she is now. How old is Katie?

Answers

1) The sum of 2 prime numbers is ALWAYS even, so if x and y are prime number,. then (x+y)/7  = z². In this case either x = 2 or y = 5 (or vice vera). This is the only possibility to be divisible by 7 . Then (5+2)/7 = 1² = 1

2) 5 pipes → 2 hours → 2 pools
then 1 pipe takes (5x2) 10 hours to fill 2 pools
or  1 pipe takes (10/2) 5 hours to fill 1 pool

3) It's 6/30 = 0.2 or 20%

4) 35% represent 7 Students, 100% of the class represent x students:
35%/7 = 100%/x
0.35/7 = 1/x (Cross multiplication) →0.35x = 7 and x = 7/0.35 → x = 20 students

5) Let K be the age of Katie and B her brother's
K + 2 = B  OR K  = x - 2 (Today)

In 12 years (B+12), B will be twice K  (remember K = B-2) →
B+12 = 2(K) OR B+12 = 2(B-2)
B+12 = 2(B-2) →
B+12 = 2B - 4→
12 + 4 = B and B = 16. If the brother is 16, then Kate is 14
:

1) There are no prime numbers whose sum is divisible by 7 and is a perfect square.

2) 1 pipe will take 2 hours to fill 1 pool, as it fills at the same rate as all 5 pipes combined.

3) Ron's score is 20%.

4) There are 20 students in the class.

5) Katie is 14 years old.

Let's evaluate each of the statements you provided:

1) The sum of 2 prime numbers is ALWAYS even, so if x and y are prime numbers, then (x+y)/7 = z².

In this case either x = 2 or y = 5 (or vice versa). This is the only possibility to be divisible by 7.

Then (5+2)/7 = 1² = 1.

The first part is correct; the sum of two prime numbers is always even. However, the statement about (x+y)/7 = z² doesn't hold true for all prime numbers. It might work for the specific values of x and y you mentioned, but it's not a general rule.

5 pipes → 2 hours → 2 pools, then 1 pipe takes (5x2) 10 hours to fill 2 pools, or 1 pipe takes (10/2) 5 hours to fill 1 pool.

This is a correct interpretation of the information provided. If 5 pipes can fill 2 pools in 2 hours, then each pipe alone takes 10 hours to fill 2 pools, or 5 hours to fill 1 pool.

It's 6/30 = 0.2 or 20%.

Correct, 6/30 simplifies to 0.2, which is equivalent to 20%.

35% represents 7 students, and 100% of the class represents x students. Therefore, 35%/7 = 100%/x. Cross-multiplying, we get 0.35x = 7, and x = 7/0.35, which simplifies to x = 20 students.

Let K be the age of Katie, and B her brother's age. K + 2 = B (Today). In 12 years, B+12 will be twice K (remember K = B-2):

B+12 = 2(K) OR B+12 = 2(B-2)

B+12 = 2(B-2)

B+12 = 2B - 4

12 + 4 = B, and B = 16. If the brother is 16, then Kate is 14.

The calculations and logic are correct. If Katie's brother is 16, then Katie is indeed 14 years old.

A plumber finished there jobs on Tuesday. The first two only cost the owner the $45 trip fee because they book very little to complete. For the third job, the plumber charged the trip fee plus 6 times his hourly rate. If the plumber received a total of $303 for the day, what is the hourly rate

Answers

The plumber's hourly rate is $43. To come to this answer, I first subtracted the $45 fee from 303. That answer was 258, which I divided by 6, because that was the number of hours the plumber worked. That answer was 43, so his hourly rate is $43.

What is the slope-intercept form of a linear equation? explain why this form is called the slope-intercept form?

Answers

The slope-intercept form of a linear equation is y=mx+b. m being the slope (part one of name) and b being the y-intercept (part 2 of name).

Answer: The slope intercept form of a linear equation has the following form where the equation is solved for y in terms of x: y = a + bx. b is the slope. a is a constant term. It is the y intercept, the place where the line crosses the y axis.

The average value of a given set of data is the mode.

True or False

Answers

false. the average value is the mean

For this case we have that by definition:

Mode: it is the value most frequently in a data distribution. This means that mode is the most repeated data in a sample or study. Mean: is the average of the data which can be found by adding all the numbers and then dividing by the number of values in the set.

Answer:

False. The average value of a given set of dates is the mean.

For what values of x is the quantity x−9 negative?

Answers

x - 9 < 0
add 9 to both sides:-
x - 9 + 9   < 9
x < 9

x - 9 is negative for all values of x less that 9.

The value of x is the quantity x−9 negative would be negative for all values of x less than 9.

What is algebra?

Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

To determine the values of x is the quantity x−9 negative

As per the given condition, translate the phrase into an algebraic expression:

⇒ x - 9 < 0

Add 9 to both sides of the inequality,

⇒ x - 9 + 9   < 9

⇒ x < 9

So x - 9 is negative for all values of x less than 9.

Hence, the value of x is the quantity x−9 negative would be negative for all values of x less than 9.
