Four consecutive even integers are such that the sum of the second and fourth is 76. What is the sum of the first and third integers?

Answers

Answer:

72

Step-by-step explanation:

Consecutive even integers have a difference of 2 between them

let n be the first integer, then

n + 2, n + 4, n + 6 are the second, third and fourth, then

n + 2 + n + 6 = 76 ( sum of second and fourth )

2n + 8 = 76 ( subtract 8 from both sides )

2n = 68 ( divide both sides by 2 )

n = 34

Thus the 4 even integers are

34, 36, 38, 40

sum of first and third = 34 + 38 = 72

Use this information for problems 1 and 2. When full, one of the pools at Sapphire Island will hold 43,000 gallons of water. The pool currently holds 20,000 gallons of water and is being filled at a rate of 130 gallons per minute.



Write an equation that can be used to find h, the number of hours it will take to fill the pool from its current level.

a
\large 130+20000\left(60h\right)=43000

b
\large 60\left(130\right)+20000h=43000

c
\large 130\left(60h\right)-20000=43000

d
\large 130\left(60h\right)+20000=43000

Answers

Answer:

The correct option is;

d. 130·(60·h)+2000 = 43000

Step-by-step explanation:

The volume of water held by a pool at Sapphire island = 43,000 gallons

The volume of water the pool currently holds = 20,000 gallons

The rate at which the pool is being filled = 130 gallons/minute

The equation to find h, the number of hours it will take to fill the pool from its current level can be written as follows;

The rate at which the pool is being filled in gallons per hour = 130 × 60 gallons/hour = 7800 gallons/hour

We have;

The volume of water pumped in h hours = (130×60) gallon/hour × h hour =  130×60×h gallons

Whereby we want the total volume of water in the pool to be 43,000 gallons, we add the volume of water obtained from pumping for hours to the volume of water already in the pool, to get 43,000 gallons as follows;

130×60×h gallons + 20,000 gallons = 43,000 gallons

Therefore, the correct option is 130·(60·h)+2000 = 43000.


Which term best describes the
quadrilateral formed by A(2, 3),
B(4, 6), C(8, 9), and D(5,5)?

Answers

Answer:

A kite

Step-by-step explanation:

The coordinates of the vertices of the quadrilateral are;

A(2, 3), B(4, 6), C(8, 9), and D(5, 5), therefore,  the length of the sides of the quadrilateral can be found using the following formula;

[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

(x₁, y₁) and (x₂, y₂) are the coordinates of the two endpoints on the side

For side AB, we have;

[tex]l_{AB} = \sqrt{\left (6 - 3 \right )^{2}+\left (4-2 \right )^{2}} = \sqrt{13}[/tex]

The slope = 1.5

For side BC, we have;

[tex]l_{BC} = \sqrt{\left (9 - 6 \right )^{2}+\left (8-4 \right )^{2}} = 5[/tex]

The slope = 3/4

For side CD, we have;

[tex]l_{CD} = \sqrt{\left (5 - 9 \right )^{2}+\left (5-8 \right )^{2}} = 5[/tex]

The slope = 4/3

For side DA, we have;

[tex]l_{DA} = \sqrt{\left (3 - 5 \right )^{2}+\left (2-5 \right )^{2}} = \sqrt{13}[/tex]

The slope = 2/3

Angle ADC = Actan (2/3 - 4/3)/(1 + 2/3*4/3) = -19.44 = 180-19.44 = 160.55°

Angle ABC = Actan (0.75 - 1.5)/(1 + 0.75*1.5) = -19.44 = 180-19.44 = 160.55°

Therefore, given that the quadrilateral has two pairs of equal adjacent sides and the angles are equal at the meeting point of the two squares, it is best described as a kite.

find the range of each of the following function. All the function are definied for all values of x.

f(x) = 3(x+5)² +2

Can you give the answer and explanation?
what does 'all the function are definied for all values of x'?

Heldpdlsoemss​

Answers

Answer:

y ≥ 2

Step-by-step explanation:

The range is all of the values that f(x) can have. In order to find the range, let's first find the vertex. That's pretty easy to do since f(x) is already written in vertex notation (vertex notation is f(x) = a(x - c)² + d where (c, d) is the vertex). Since c = -5 and d = 2, the vertex is (-5, 2). Because the value of a is positive (a = 3 in this case, which is positive) we know that the parabola opens upward, therefore the vertex is the minimum. This means that the y-coordinate of the vertex is the smallest possible y-value of the function, therefore, since the y-coordinate of the vertex is 2, the range is y ≥ 2. Note that we use ≥ and not >, this is because y can be 2, therefore, it is included in the solution set.

Answer:

Hey there!

First, we must understand what range is. Range is just another word for all the possible y values of the equation.

This equation, f(x) = 3(x+5)² +2 is in vertex form. We see that this creates a parabola with a vertex at (-5, 2) and opens up.

Thus, the range of this graph would be: [2,∞) in interval notation. Note, the [ is used for greater than or equal to, or less than or equal to, and the ")" is used for less than or greater than.

We use ) for ∞, because ∞ is just a concept, not a real number.

Finally, all functions are defined for all values of x means that this is an f(x) function, and the f(x) is equal to something that can be written in terms of x.

Johnathan makes $27 per hour and works 25 hours per week. Every week, he has to sell 20 items. If he sells more than 20 items in a week, he receives a commission of 14% on each set of additional 5 items he sells. This week he worked for 25 hours, he sold 25 items, and he made $1,000 in sales beyond the required 20 items. Which equation will help Johnathan to compute this weeks income?

Answers

Answer:

Total income = 27 [tex]\times[/tex] 25 + 14% of $1000= $815

Step-by-step explanation:

Number of hours for which Johnathan worked = 25

Salary for each hour = $27

So, income for 25 hours = 25 [tex]\times[/tex] 27 = $675

Now, it is given that he has sold 25 items.

Sales made beyond the 20 items = $1000

Additional income for additional sales = 14% on each set of 5 items

He has sold exactly 5 additional items that means 1 set of 5 additional items.

So, Additional income for additional sales = 14% [tex]\times[/tex] 1000 = $140

Therefore, total income of this week = Income for 25 hours + Income due to additional sales of 5 items

Therefore Total income = 27 [tex]\times[/tex] 25 + 14% of $1000= $815

How many times greater is the value of 4 in 4735 than the value of the 4 in 6412

The x terms add to x+x = 2x.

The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away

The constants add to 5+7 = 12

The z terms add to -z+z = 0z = 0 and those go away as well

After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.

Answers

Answer:

width = 6 feet

Step-by-step explanation:

let l be the length of the rectangle

let w be the width of the rectangle

The statement

The length of a rectangle is 6 feet more than three times the width of the

rectangle is written as

l = 6 + 3w

From the question

l = 24 feet

Substitute the value into the above formula and solve for the width

That's

24 = 6 + 3w

3w = 24 - 6

3w = 18

Divide both sides by 3

w = 6

Therefore

width = 6 feet

Solve for x in the equation below(all in picture).

Answers

Answer:

x = - 5, x = 2

Step-by-step explanation:

Using the rules of logarithms

log x - log y = log ([tex]\frac{x}{y}[/tex] )

[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]

note that log x = [tex]log_{10}[/tex] x

Given

log (x² + 3x) - log10 = 0, then

log([tex]\frac{x^2+3x}{10}[/tex] ) = 0, thus

[tex]\frac{x^2+3x}{10}[/tex] = [tex]10^{0}[/tex] = 1 ( multiply both sides by 10 )

x² + 3x = 10 ( subtract 10 from both sides )

x² + 3x - 10 = 0 ← in standard form

(x + 5)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 2 = 0 ⇒ x = 2

Solution is x = - 5, x = 2

Answer:

The equation has the solution(s) x = - 5, and x = 2

Step-by-step explanation:

Let's start by adding log(10) to either side of the equation --- (1)

[tex]\log _{10}\left(x^2+3x\right)-\log _{10}\left(10\right)+\log _{10}\left(10\right)=0+\log _{10}\left(10\right)[/tex]

= [tex]\log _{10}\left(x^2+3x\right)=\log _{10}\left(10\right)[/tex]

If you recall, one property proves that [tex]\log _{10}\left(10\right):\qu 1[/tex]. We can substitute this value back into the simplified equation --- (2)

[tex]\log _{10}\left(x^2+3x\right)=1[/tex]

We can also apply the logarithmic definition, If logₐ(b) = c then b = aᶜ. Using this definition we receive a further simplified equation --- (3)

[tex]x^2+3x=10^1[/tex]

[tex]x^2+3x=10[/tex]

Solving for the expression we receive the solution(s) x = 2, and x = - 5, our first option.

Answers

Answer:

Since the line divides the cup into one - eighth

The number of 1/8th's obtainable from 1 3/4 :

1 3/4 = 7/4

7/4 divided by 1/8th

7/4 ÷ 1/8

7/4 × 8/1

14 gives the upper limit of the line starting from the bottom, Therefore, a measurement of 1 3/4 should be between the 13 th and 14 th line. Since the bottom of the cup will have no line.
