The Product Of 2 Numbers Is -33 Whereas Their Difference Is -12. Find The Numbers. Hint: There Are 2

Answers

Answer 1

Answer:

Let the two nos. Be x and y

xy = -32

x - y = -12

(x-y)^2 = (x+y)^2 - 4xy

144 = (x+y)^2 + 128

16 = (x+y)^2

Therefore x+y = +4, -4

When x+y = +4, x-y = -12

x = -4, y = 8

When x+y = -4, x-y = -12

x= -8, y = 4

Hope this helps!

The price of a toaster increase 10% to $40. What is the original price of the toaster before the increase?

Answers

Answer:

36.36

Step-by-step explanation:

We can express 10% as a decimal by multiplying it by (1/100), resulting in 0.1. Therefore, adding 0.1 of the original price, or x, to the price will result in 40, so x+0.1*x=40

          = 1.1x

Dividing both sides by 1.1, we get that x, or the original price, is $36.36 (approximately).

the diameter of the sweep of the main rotor of the eh101 helicopter is 18.6 meters. A toy model of it has a sweep of 31 centimeters. What is the scale of the model?

Answers

Answer:

The actual length of 60 cm is modeled as 1 cm length.

Step-by-step explanation:

The diameter of the sweep of the main rotor of the helicopter is 18.6 meters i.e. 1860 cm.

Now, the toy model of the helicopter has a sweep of 31 cm.

Therefore, the scale in which the model is made is 1860 : 31 i.e. 60 : 1 ratio.

So, the actual length of 60 cm is modeled as 1 cm length. (Answer)

Answer:

The scale of the model to the actual is 1:60

Step-by-step explanation:

The scale of the model may be computes as the ratio of the diameter of the original sweep to the diameter of the model. Given that the diameter of the sweep of the main rotor of the eh101 helicopter is 18.6 meters and that of the model is 31 cm, the scale of the model

= 31cm to 18.6m

since 100cm = 1m,

18.6m = 18.6 * 100cm

= 1860 m

31cm to 18.6m = 31cm to 1860cm

= 1 to 60

Answer:

y = -2x - 1

Step-by-step explanation:

Formula is y = mx + b

m = slope

slope = change in y/change in x = (-1 - 3) / (0 - -2) = -4/2 = -2

So equation is now y = -2x + b

To find b, substitute any value from the table into the equation. Let's use (-2,3)

y = -2x + b

3 = -2(-2) + b

3 = 4 + b

-1 = b

So equation is y = -2x - 1

Answer:

C. This can be found by looking at when x=0. If y=-1, then that means that the y intercept is -1, so plug in 1 to either one of the middle two equations and see if it works.

What are the possible values of the missing term of the geometric sequence 6,....,13.5?

Answers

Next term=9

Multiply by 1.5
6*1.5=9
9*1.5=13.5

Answer:

THE ANSWER IS 1.5

Step-by-step explanation:

13.5 is the 3rd and last value. 6 is the first value.

The formula you need to use is an= 3r^n-1

13.5=3r^3-1

THE REASON YOU USE 3 IS BECAUSE IN TOTAL THERE ARE 3 TERMS AND WE ARE SOLVING FOR ONE MISSING TERM.

Now we bring 3 over to 13.5 to get r alone because we are solving for r

13.5/3 =r^2

Now we want to get rid of the square root. So we...

√13.5/3 =√r^2

The final answer is 1.5=2

Write the quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4.

Answers

The quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4, is: [tex]\[\bo{4x^2 - 36x + 80 = 0}\][/tex]

Step 1

To write a quadratic equation with given roots and a specified leading coefficient, we can use the fact that if p and q are the roots of a quadratic equation, the equation can be written as:

[tex]\[a(x - p)(x - q) = 0\][/tex]

where a is the leading coefficient.

Given roots: [tex]\( p = 4 \)[/tex] and [tex]\( q = 5 \)[/tex]

Leading coefficient: [tex]\( a = 4 \)[/tex]

Step 2

Let's substitute these values into the equation:

[tex]\[4(x - 4)(x - 5) = 0\][/tex]

Now, we need to expand this equation. First, expand the product [tex]\((x - 4)(x - 5)\):[/tex]

[tex]\[(x - 4)(x - 5) = x^2 - 5x - 4x + 20 = x^2 - 9x + 20\][/tex]

Step 3

Next, multiply this expression by the leading coefficient [tex]\( 4 \)[/tex]:

[tex]\[4(x^2 - 9x + 20) = 4x^2 - 36x + 80\][/tex]

Thus, the quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4, is:

[tex]\[\bo{4x^2 - 36x + 80 = 0}\][/tex]

An airliner is 9.34 feet wide. The airline wants to install 5 seats in each row. The seats are each 1.46 feet wide. Rounded to the nearest tenth, about how much space would be left for the aisle?

Answers

About 2.0 feet space will be left for aisle.

Step-by-step explanation:

Width of airliner = 9.34 feet

Width on one seat = 1.46 feet

Seats to install = 5

Width of 5 seats = 5*1.46 = 7.3 feet

Space left for aisle = Width of airliner - width of 5 seats

[tex]Space\ left\ for\ aisle=9.34-7.3\\Space\ left\ for\ aisle=2.04\ feet[/tex]

Rounding off to nearest 10th

Space left for aisle = 2.0 feet

About 2.0 feet space will be left for aisle.

brainly.com/question/10435836brainly.com/question/10541435

#LearnwithBrainly

Final answer:

To find the space left for the aisle, we first calculate the total seat width (5 seats × 1.46 feet/seat) and subtract it from the airliner width (9.34 feet), resulting in 2.0 feet of space for the aisle when rounded to the nearest tenth.

Explanation:

To calculate the available space for the aisle in an airliner, we first determine the total width consumed by the seats. Since each seat is 1.46 feet wide and there are 5 seats in a row, we multiply the width of one seat by the number of seats:

1.46 feet/seat × 5 seats = 7.3 feet

Next, we subtract the total width of the seats from the total width of the airliner to find the space left for the aisle:

9.34 feet (total width) - 7.3 feet (width of seats) = 2.04 feet

Therefore, rounded to the nearest tenth, there would be approximately 2.0 feet of space left for the aisle.

The equation of the function represented by the table is y = 5 x + 2

Step-by-step explanation:

The equation of the linear function in the slope-intercept form is

y = m x + b, where

m is the slope of the lineThe formula of the slope is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] , where [tex](x_{1},y_{1})[/tex] and [tex](x_{1},y_{1})[/tex] are any two points lie on the lineb is the y-intercept, means the line intersects the y-axis at point (0 , b)

The table:

→  y  :    2    :    7    :    12  :    17   :    22

Let us chose any two points from the table to calculate the slope

∵ Points (1 , 7) and (2 , 12) lie on the line

∴ [tex]x_{1}[/tex] = 1 and [tex]x_{2}[/tex] = 2

∴ [tex]y_{1}[/tex] = 7 and [tex]y_{2}[/tex] = 12

- Substitute these values in the formula of the slope

∵ [tex]m=\frac{12-7}{2-1}=\frac{5}{1}[/tex]

m = 5

Substitute the value of m in the form of the equation

∵ y = m x + b

∴ y = 5 x + b

∵ The line intersects the y-axis at point (0 , b)

∵ From the table point (0 , 2) lies on the line

b = 2

∴ y = 5 x + 2

The equation of the function represented by the table is y = 5 x + 2

Answer:

Length of the rectangle is [tex]18.85\ inches[/tex],and the width of the rectangle is [tex]16.35\ inches[/tex]

Step-by-step explanation:

Let the width of the rectangle be [tex]x[/tex] inches

Then

The length of the rectangle will be [tex]x+2.5[/tex] inches

So perimeter [tex]=2(length + width)[/tex]

Plugging the values:

⇒ [tex]2(x+x+2.5)=75.4[/tex]

⇒ [tex]2(2x+2.5)=75.4[/tex]

⇒ [tex]4x+10=75.4[/tex]

  Subtracting [tex]10[/tex] from both sides.

⇒ [tex]x=\frac{65.4}{4}=16.35\ inches[/tex]

  So the width of the rectangle is [tex]16.35\ inches[/tex]

   And the length of the rectangle is [tex]18.85\ inches[/tex]

The expression x2 - 36y2 is equivalent to​

Answers

Answer:

(x + 6y)(x - 6y)

Step-by-step explanation:

The expression x² - 36y² can be factored.

Since the expression is a difference (subtraction) between two numbers that are square (x² = x*x and 36y² = 6y*6y), the factoring can be done as a "difference of squares".

The rules is generalized as: [tex]x^{2} - y^{2} = (x - y)(x+y)[/tex]

To factor x² - 36y², take each square roots for each of the numbers and add and subtract between them.

x² - 36y²

= (√x² + √36y²)(√x² - √36y²)

= (x + 6y)(x - 6y)

Which of the following lines is parallel to x = 4
O 1) 3y = 9
O 2) y = 4
O 3) x = 2
O4) x = y

Answers

Answer:

O4) x = y

Step-by-step explanation:

I took this before

The answer is 3) x = 2.
If you graph each of the answer choices, you are able to see which line is parallel to x = 4. x = 4 is a vertical line that crosses the x axis at (4, 0)

Answer 1 simplifies to y = 3, which is a horizontal line that crosses the y axis at (0, 3). Since it is a horizontal line, we can rule it out.

Answer 2 is also a horizontal line that crosses the y-axis at (0, 4). Since it is a horizontal line, we can rule it out.

Answer 3 is a vertical line that crosses the x-axis at (2,0). Since x = 2 and x = 4 are both vertical lines that do not intersect, they are parallel.

Answer 4 is a diagonal line that crosses through points in the first and third quadrant such as (1, 1) and (-2, -2). Since this is not a vertical line, we can rule this out as well.

The answer is 3) x = 2.

Marty ordered three extremely accurate and scientific water-balloon launchers from a mail order catalog (one for himself and two for his friends). The total price including shipping charges was $50. If the total shipping cost was $5, how much did each launcher cost?

At the market, 8 apples cost $4dollar. How much do 9 apples cost?

Answers

Answer: $4.50 for 9 apples

Step-by-step explanation: To find out how much it is for 1 apple, we need to find the unit price of 1 apple which is the cost per apple.

Since we know that it costs $4 for 8 apples, to find the cost for 1 apple, we need to divide 8 into $4 or 4 divided by 8 which is 0.5 of 50 cents per apple.

Since we know that it costs 50 cents per apple, to find the cost for 9 apples, we will need to multiply .50 by 9.

(.50) (9) = 4.50

Therefore, it will cost $4.50 for 9 apples.

If you buy a home and make a relatively small down payment, what happens to the monthly payments and total payment for you loan?

Answers

Answer:

Both monthly payment and total payment will increase.

Step-by-step explanation:

If I buy a home and make a relatively small down payment, then the due payment will be more.

If I pay for my home through a bank and I fix the number of installments to pay back the due amount after down payment (say, monthly installment for 5 years), then the amount of installment payment will definitely increase if my down payment is less.

Again, if the down payment is less, the remaining amount to pay back will rise and the bank calculates interest on the remaining amount to pay. Therefore, the amount of interest will rise in value and finally the total payment after interest for my loan will increase. (Answer)

Busses 25 people but are much more expensive to rent passenger vans for 12 people. Create a system of equations to find the small list number of buses there orchestra can rent.

Answers

Answer:

Small list number of buses [tex]=3[/tex],the orchestra can rent.

Step-by-step explanation:

Form an equation representing the number of vehicles needed.

Let the number of buses be [tex]x[/tex] and the number of vans be [tex]y[/tex]

We have six drivers so,

[tex]x + y\leq 6[/tex] for both vehicles.

And it's an inequality,where we can equate with by removing the inequality to close in our answer.

[tex]x + y = 6[/tex]

Then form an equation representing the total number of seats [tex]K[/tex] in vehicles for the orchestra members.

[tex]25[/tex] people for bus and [tex]12[/tex] people for vans can be written in terms of seats.

So,[tex]K = 25x + 12y[/tex]

In terms of an inequality it can be written as,

[tex]25x + 12y\geq111[/tex],[tex]111[/tex] is the maximum numbers of the orchestra.

Solving the system of inequality.

We have

[tex]x + y = 6[/tex]

Re-arranging y.

[tex]y = 6 - x[/tex]

Plugging the values in [tex]25x + 12y\geq111[/tex] by removing the inequality and considering it as an equation.

[tex]111 = 25x + 12y = 25x + 12(6-x)[/tex]

[tex]111 = 25x + 72 - 12x[/tex]

[tex]111 - 72 = 13 x[/tex]

[tex]39 = 13 x[/tex]

[tex]x = 3[/tex]

So small list number of buses are [tex]3[/tex] there orchestra can rent.

Answers

Final answer:

The question pertains to writing an equation for a mathematics-related scenario, emphasizing the importance of understanding equations as expressions of concepts rather than just tools for calculation.

Explanation:

The subject of this question appears to revolve around forming an equation that could pertain to a mathematics problem. The use of mathematical equations to convey concepts is crucial; they aren't just mechanisms for inserting and churning numbers, but they are sentences that express concepts precisely and purposefully. Writing out such equations in both words and symbols ensures comprehension of the underlying reasoning.

Moreover, when teaching mathematics, it's beneficial to allow students to create their own formulas. This practice not only solidifies the understanding of concepts but also emphasizes that the symbols used in equations are arbitrary and that what matters is the concept they represent.

Remembering the correct order of operations is essential, which can be recalled with the mnemonic 'Please Excuse My Dear Aunt Sally.' Also, an iterative relation often used in advanced mathematics is not an equation per se, but rather a set of instructions for approximating a solution. This iterative process requires a different approach compared to straightforward equation solving.
