One number is 20 more than two times another. Find the two numbers if their sum is 110.

One Number Is 20 More Than Two Times Another. Find The Two Numbers If Their Sum Is 110.

Answers

Answer 1

Answer:

30, 80

Step-by-step explanation:

Let the smaller number be [tex]x[/tex]. Then, the other number is [tex]2x+20[/tex]. The sum is 110, so

[tex]x+(2x+20)=110.[/tex]

Simplifying gives

[tex]3x+20=110[/tex].

Subtracting 20 from both sides gives

[tex]3x=90[/tex].

Dividing by 3 gives

[tex]x=30[/tex].

The smaller number is 30 and the larger number is 2(30)+20=80.

The Parks and Rec department has an opening for a Solver of Linear Equations. Since Leslie is great at solving systems of linear equations she zealously offers to give all candidates a quick demonstration. She finds the LU factorization of a 2000 x 2000 matrix in 78125 seconds. She then takes another 25 seconds to apply both triangular substitutions (backward and forward) to solve the system of equations Mx = y for a given vector Y.
The candidates are supposed to estimate (without actually running any code) the time it takes to factorize and efficiently solve a similar system of linear equations Ax =b, where A is a square matrix with dimension 500, given 30 different right-hand side b vectors.

Answers

Matrix are used to show data in rows and columns

The estimated time to efficiently solve the square matrix A is 4907.8125 seconds

How to estimate the time to solve matrix A

The given parameters are:

Matrix size = 2000 by 2000

Time = 78125 seconds

Substitution time = 25 seconds

The time to solve the matrix is dependent on the size of the matrix, while the substitution time is fixed

The size of the similar matrix is 500 by 500

The similar matrix is 1/16 smaller than the original matrix of 2000 by 2000.

So, the time to factorize the matrix is:

[tex]Time = \frac{1}{16} * 78125\ seconds[/tex]

[tex]Time = 4882.8125\ seconds[/tex]

The estimate of the time to solve the new matrix is the sum of the time to factorize it and the substitution time.

So, we have:

[tex]Total = 4882.8125\ seconds + 25\ seconds[/tex]

This gives

[tex]Total = 4907.8125\ seconds[/tex]

Hence, the estimated time to efficiently solve the square matrix A is 4907.8125 seconds

The system of two quadratic equation is

x² + 6x + 9 = 0

x² - 9 = 0

What is a quadratic equation?

"A quadratic equation is an algebraic equation of the second degree in 'x'. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a'(a ≠ 0) and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term."

The solution of the first equation in the system is (- 3, - 3).

Therefore, the equation will be

[x - (- 3)] [x - (- 3)] = 0

⇒ (x + 3)(x + 3) = 0

⇒ (x + 3)² = 0

⇒ x² + 6x + 9 = 0

The solution of the second equation in the system is (3, - 3).

Therefore, the equation will be

[x - 3] [x - (- 3)] = 0

⇒ (x - 3)(x + 3) = 0

⇒ (x)² - (3)² = 0

⇒ x² - 9 = 0

What is the length of minor arc SV? 20π in. 28π in. 40π in. 63π in.

Answers

Angles and arcs' lengths are related to each other. The length of the minor arc SV is given by: Option A: [tex]20\pi \: \rm inches[/tex]

How can we use a full rotation?

Whole circumference is covered by 360 degrees rotation.

How  to find the relation between angle subtended by the arc, the radius and the arc length?

[tex]2\pi^c = 360^\circ = \text{Full circumference}[/tex]

The superscript 'c' shows angle measured is in radians.

If radius of the circle is of r units, then:

[tex]1^c \: \rm covers \: \dfrac{circumference}{2\pi} = \dfrac{2\pi r}{2\pi} = r\\\\or\\\\\theta^c \: covers \:\:\: r \times \theta \: \rm \text{units of arc}[/tex]

The complete problem specifies radius of the circle as 24 in. and

θ = 5pi/6

Thus, we get the measurement of the arc length that angle covers as:

[tex]r \times \theta \: \rm inches = 24 \times \dfrac{5\pi}{6} = 20\pi \: \rm inches[/tex]

A group of friends goes out to lunch and decides to split the bill. Their bill is $32. 50, plus they want to leave a 20% tip. The final amount will be split 4 ways. What is the amount each person will pay? $7. 50 $8. 15 $9. 20 $9. 75.

Answers

Percent counts the number of a quantity compared to another quantity's 100 amount. The amount each person would pay is given by: Option D: $9. 75

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For the given case,

Bill for lunch = $32.50

Tip  = 20% of bill = [tex]\dfrac{32.50}{100} \times 20 = \dfrac{32.50}{5} = 6.50[/tex] (in dollars)

Total amount = Bill + Tip = $39

This amount has to be divided in 4 equal part.

Thus, each part of those 4 parts would be [tex]\dfrac{39}{4} = 9.75[/tex] (in dollars).

Thus, the amount each person would pay is given by: Option D: $9. 75

F represents the fee (in dollars) for climbing d meters.

F = 110 +0.12d

What is the increase in price for every 100 meters climbed?

Answers

Answer:

$12

Step-by-step explanation:

when d = 0,  F = 110

when d = 100, F = 110 + (0.12 x 100) = 122

when d = 200, F = 110 + (0.12 x 200) = 134

etc.

Therefore, increase in price for every 100 meters climbed = 134 - 122 = 122 - 110 = 12

JL ≈ 3.1

Step-by-step explanation:

Using the cosine rule

with JL = k , JK = l , KL = j , then

k² = j² + l² - (2jlcosK )

   = 6² + 8² - ( 2 × 6 × 8 × cos20° )

    = 36 + 64 - (96cos20°)

    = 100 - 96cos20° ( take square root of both sides )

k = [tex]\sqrt{100-(96cos20)}[/tex] ≈ 3.1 ( to the nearest tenth )

that is JL ≈ 3.1
