x²=169 extracting square root​

Answers

Answer 1

Answer:

x = ± 13

Step-by-step explanation:

Given

x² = 169 ( take the square root of both sides )

x = ± [tex]\sqrt{169}[/tex] = ± 13

Since 13 × 13 = 169 and - 13× - 13 = 169

5(x + 2) = 2(x – 4)
–4(x + 3) = 4(–x – 1)

Answers

Answer:

1 and 5

Step-by-step explanation:

1. 6x + 1 = 3(2x - 4)

6x + 1 = 6x - 12

6x + 13 = 6x

-6x         -6x

    13 = 0x

no solution

2. 2-5x = 7x - 12

    2 = 12x - 12

    14 = 12x

    1 1/6 = x

3. 4(3 - x) = 2(6 - 2x)

  12 - 4x = 12 -4x

    -4x = -4x

   x = ∞

4. 5(x + 2) = 2(x - 4)

   5x + 10 = 2x - 8

   3x + 10 = -8

   3x= -18

   x = -6

5. -4(x + 3) = 4( -x - 1)

   -4x -12 = -4x -4

    -4x - 8 = -4x

     -8 = 0x

The table above shows the high temperature last Thursday for five cities, A through E. If the median of the Thursday high
temperature for these cities was 81°F, which of the following could NOT have been the high temperature last Thursday of city
A?

Answers

Answer:85

Step-by-step explanation:

[tex]F[/tex]High temperature last Thursday of city is [tex]85[/tex]°

(A) is correct. If the median of the Thursday high temperatures for the five cities was

        [tex]81[/tex]°[tex]F[/tex],then the five high temperatures are listed in order from greatest          

         to least (or least to greatest),

                A.[tex]85[/tex]°[tex]F[/tex]

                B.[tex]75[/tex]°[tex]F[/tex]

               C.[tex]65[/tex]°[tex]F[/tex]

               D.[tex]55[/tex]°[tex]F[/tex]

Since the three greatest known high temperatures are [tex]91[/tex]°[tex]F[/tex]., [tex]87[/tex]°

        [tex]81[/tex]°[tex]F[/tex].

[tex]81[/tex]°[tex]F[/tex] must be the third temperature in the list.The unknown high temperature for City A must be less than or equal to

         [tex]81[/tex]°[tex]F[/tex].

Thus, [tex]85[/tex]°[tex]F[/tex] is NOT less than or equal to [tex]81[/tex]°Therefore only [tex]85[/tex]°[tex]F[/tex] could NOT have been the high temperature last Thursday for City A.

The highest point in Argentina is 6,960 meters above sea level. The lowest point is 105 meters below sea level. What is the difference between the highest and lowest points?

Answers

Answer:

7,065 meters.

Step-by-step explanation:

The problem is asking for "the difference" between two points. "The difference" means you're subtracting. The second point says it is below sea level, though. That makes it a negative number. Thus:

[tex]6960-(-105)=x[/tex]

When subtracting by a negative number, think of it as addition, since the negative cancels out the subtraction sign. This turns it into:

[tex]6960+105=7065[/tex]

There is a 7,065 meter difference between the two points.

A home improvement store advertises 60 square feet of flooring for $287.00. The price includes an $80.00 installation fee. How much does each square feet of flooring cost, including the installation fee? Your answer, in dollars and cents, should be a decimal rounded to the nearest hundredth (penny).

Answers

Answer:

$4 78 cents

Step-by-step explanation:

If home improvement store advertises 60 square feet of flooring for $287.00 ($80 installation fee inclusive), to get the price per square feet of the flooring cost, we will use the expression;

60 sq.ft = $287

1 sq. ft = $x

Cross multiply

60x = 287

Divide both sides by 60

60x/60 = 287/60

x = 4.783

x ≈ 4.78 (to the nearest hundredth)

Hence the price per square feet of the flooring is $4.78 or $4 78 cents

Note that $80 was not added to $287 because we are told that this price ($287) already includes the installation fee.

The factors of -24 are listed in the table. Which factors of -24 are used to factor x-5x - 24 ?​

Answers

-8,3

-8*3 = -24

The factors of -24 which should be used to factorize the given quadratic equation are -8 and 3.

It is required to factorize the quadratic equation [tex]x^2-5x - 24[/tex] using the factors of -24.

The required combination of factors should be -8 and 3 because,

[tex]-8+3=-5\\-8\times3=-24[/tex]

Now, factorize the quadratic equation as,

[tex]x^2-5x - 24=x^2-8x+3x-24\\=x(x-8)+3(x-8)\\=(x-8)(x+3)[/tex]

Therefore, the factors of -24 which should be used to factorize the given quadratic equation are -8 and 3.

Bradley went on a bike ride to the store 6 miles away. If it took Bradley 38 of an hour to get there and 14 of an hour to get back, what was his average rate of speed (miles per hour) for the entire trip? (Hint: To find the average, divide the total distance by the total duration.)

Answers

Answer:

19.2

Step-by-step explanation:

The average speed for the entire trip was 0.23 miles per hour.

What is average speed?

The average speed is the total distance travelled by the total time taken to travel the distance. It does not depend upon the instantaneous speed of the object.

The total distance of the store is 6 miles.

The time taken to reach is 38 hour.

And, the time to come back is 14 hours.

Since, the average  speed is given as the ratio of the  total distance to the total time.

Here, the total distance is 2 times the given distance.

Thus, the average speed is found as.

(6 + 6)/ (14 + 38)

= 12/52

= 3/13

= 0.23

Hence, the average rate of speed for the entire trip is 0.23 miles per hour.

A tree measured 18 feet tall. Over the next 3 1/2 years, it grew to final height of 35 1/2 feet. During those 3 1/2 years, what was the average yearly
Growth rate of the height of the tree

Answers

Answer: it 5 feet/yard

Step-by-step explanation:

The average yearly growth rate the tree is 5 feet per year.

What is rate?

Rate is a measurement to determine the change in one quantity with respect to another quantity.

Given that,

Height of tree = 18 feet

Also, the tree grew in next 3 ¹/₂ years,

Since the tree grew to final height of 35 ¹/₂ or 71/2 feet.

The increased height of the tree = 71/2 - 18 = 35/2

To find the average growth rate of the height of the tree,

Use ratio method,

In 3 ¹/₂ years = 35/2 feet,

In 7/2 years = 35/2 feet,

in 1 year = 5 feet

The average growth rate of the height of the tree is  5 feet per year.
