Answer:

bsgdhv is the ghj is the most

Answer:

4 more hours.

Step-by-step explanation:

So, to calculate the remaining time Jill has to drive, we have to first find out how much distance Jill has left to cover:

[tex](450 - 250)[/tex] miles

= [tex]200[/tex] miles

So, at a rate of 50 miles per hour, Jill has to drive:

[tex]\frac{200}{50}[/tex] more hours

= [tex]4[/tex] more hours

Hope this helped!

Answer:

Step-by-step explanation:

This is a difference of squares.

√x^2 - √49  is the basic formula for factoring a difference of squares. The  idea is that the middle term has been cancelled out.

√x^2 = x

√49 = 7

(x - 7)(x + 7) is the way this factors.

(x - 7)(x + 7)

===========

(x + 7)

The (x +7) in the numerator cancels with the (x + 7) in the denominator.

The answer is (x - 7)

====================================================

She might have wanted you to do it like this.

(x + 7) || x^2  + 0x    - 49  || x     -   7

            x^2 + 7x  ........... Subtract

           ==========

                   -7x      - 49

                   -7x      - 49   ...... Subtract.

                   =============

                           0

Or she might have seen you do this

x^2 - 49          x^2        49

=======   =   ===    -   =====

x + 7                x             7

Every math teacher freaks when they see this. I hope I didn't put ideas in your head.

But if you got the answer by doing what I did, you got it right.  

Answer:

= 27

Step-by-step explanation:

x + 18 = 45

   -18      -18

x = 27

Answer:

Anjali ran 27 miles.

Step-by-step explanation:

So if you make that 8 an 18 it would be right. Hope this helps!

The rule states that

[tex](a^b)^c = a^{bc}[/tex]

So, in your case, you have

[tex](9^{\frac{1}{2}})^2=9^{\frac{1}{2}\cdot 2}=9^1=9[/tex]

Trying to factor by pulling out :

3.2 Factoring: 3m3 + 5m2 - 5m + 1

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -5m + 1

Group 2: 5m2 + 3m3

Pull out from each group separately :

Group 1: (-5m + 1) • (1) = (5m - 1) • (-1)

Group 2: (3m + 5) • (m2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator :

3.3 Find roots (zeroes) of : F(m) = 3m3 + 5m2 - 5m + 1

Polynomial Roots Calculator is a set of methods aimed at finding values of m for which F(m)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers m which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 3 and the Trailing Constant is 1.

The factor(s) are:

of the Leading Coefficient : 1,3

of the Trailing Constant : 1

Let us test ....

P Q P/Q F(P/Q) Divisor

-1 1 -1.00 8.00

-1 3 -0.33 3.11

1 1 1.00 4.00

1 3 0.33 0.00 3m - 1

The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

In our case this means that

3m3 + 5m2 - 5m + 1

can be divided with 3m - 1

Answer:

printer A-  36/1.5

printer B-  114/3

printer C-  115/5

first, multiply 1.5 x 10, 3 x 5, and 5 x3

you should get 15 for each.

once you have the denominators all done, multiply the numerators by the value you multiplied the denominator by and you should have your answer.

so all in all, printer B prints the fastest

Answer:

C. y = 10x + 25

Step-by-step explanation:

If John put $10 each week but we don't know how many weeks that he deposits $10, use x as the amount of weeks. x10.

There was already $25 in his savings account so we don't have to put an x next to the $25.

Answer:

Step-by-step explanation:

cm= (K2-15) in cm = (10k +9) in

K2 - 15 = 10k + 9

K2 - 10k = 9 + 15

K2 - 10k = 24

2k - 10k = 24

-8k = 24

k = - 3

Answer:

26kg

Step-by-step explanation:

Firstly, we need to find 1/5 of 65kg so we do: 65/3=13

Then, to find 3/5 of 65kg we multiply 13*3 to get 39

Lastly, we subtract 39 from 65 to get 26kg

Answer: 10 hours

Step-by-step explanation:

First and foremost, we should note that:

Speed = Distance / Time

Total destination = 610 miles

Loretta speed = 55 mph

Time to be used by Loretta = 4 hours

Loretta's distance = Speed × Time = 55 × 4 = 220 miles

The distance to be covered by her dad will then be:

= 610 - 220

= 390 miles

Her dad's average speed = 65 mph.

Time taken by her dad will be:

= 390 / 65

= 6 hours

The number of hours to be used by the family will then be:

Time taken by Loretta + Time taken by her dad

= 4 hours + 6 hours

= 10 hours

Answer:

$1

Step-by-step explanation:

To find out how much more money Olivia spent per apple, we need to find out how much each spent on one apple.

Cassie:

2 apples --- $4

1 apple --- $4 ÷ 2 = $2

Olivia:

5 apples --- $15

1 apple --- $15 ÷ 5 = $3

Difference per apple = $3 - $2

                                   = $1

Answer:

89.10 / 4.95 is 18. so the first one is 18.

6 and 9, so we have to find the LCM. 6,12,18 and 9,18, so the first one to get a red and blue cap is the 18th bottle.

We know that the 18th bottle will get a red and blue, so then we have to find the LCM of 18 and 10. 18,36,54,72,90  10,20,30,40,50,60,70,80,90.

The first one to get all three is  the 90th bottle.

Hope this helps plz hit the crown :D

Answer:

35, 35, and 50

Step-by-step explanation:

50 + x + x = n

n ÷ 3 = 40

n = 40 x 3

n = 120

50 + 2x = n

50 + 2x = 120

2x = 120 - 50

2x = 70

2x/2 = 70/2

x = 35

To check:

35 + 35 + 50 = 120

120 ÷ 3 = 40

Hope this helps

Answer:

35

Step-by-step explanation:

let us take each boy's weight as x

therefore,

average = [tex]\frac{x+x+50}{3\\}[/tex]

40 = [tex]\frac{x+x+50}{3\\}[/tex]

40 x 3 = x + x + 50

120 - 50 = 2x

70 = 2x

2x = 70

x = [tex]\frac{70}{2}[/tex]

x = 35

So weight of each boys is 35.

Answer:

I think that it is something to do with the atmosphere and the way that the light bounces around it. Here is some information from a website to back this up. "The Short Answer: Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves."

Answer:

the blue sky is caused by sunlight reaching earth atmosphere which is scattered by the gases and air particles. which blue light is scattered more so that is why the sky is blue

Answer:

2 and 20

Step-by-step explanation:

First how can we get rid of the fraction?

We can multiply -1/2 by 2 to get -1

Next what number do we multiply to get from -1 to -20?

-1x = -20

divide both sides by -1

x = 20

Step-by-step explanation:

Since angles in the same segment are equal, Angle ABC (x) = Angle AOC.

Since Angles AOC and COD are supplementary, Angle AOC = 180° - 130° = 50°

Therefore x = 50°.

Answer:

1). x = 14

2). y = 2.4 cm

Step-by-step explanation:

In the diagram ΔNPQ ~ ΔNLM and NL = 3,

1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]

   (3x + 18)° = 60°

   3x = 60 - 18

   x = 14

2). Since, both the triangles are similar, corresponding sides will be proportional.

   [tex]\frac{PN}{NL}=\frac{NQ}{NM}[/tex]

   [tex]\frac{y}{3}=\frac{3.2}{4}[/tex]

   y [tex]=\frac{3.2\times 3}{4}[/tex]

   y = 2.4 cm

Answer: 3.75 + - 7

Step-by-step explanation:

1.5x + 1.5x + 0.75x - 3 + - 3 + - 1

3.75x + - 7

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

Putting all the values of y=9, 6, 0, and -3 to complete the table

FOR y=9

putting y=9

switch sides

subtract 3 from both sides

Hence,

when y=9, x=4

FOR y=6

putting y=6

switch sides

subtract 3 from both sides

Hence,

when y=6, x=2

FOR y=0

putting y=0

switch sides

subtract 3 from both sides

Hence,

when y=0, x=-2

FOR y=-3

putting y=-3

switch sides

subtract 3 from both sides

Hence,

when y=-3, x=-4

Hence, the table becomes:

x                     y

9                    4

6                    2

0                    -2

-3                   -4

Answer:

Step-by-step explanation:

This problem can be worked in your head.

If the perimeters of the square and regular octagon are the same, the side length of the 4-sided square must be the same as the length of 2 sides of the 8-sided octagon. Since the side of the square is 6 ft more than the side of the octagon, each side of the octagon must be 6 ft, and each side of the square must be 12 ft.

__

We can let s represent the side length of the octagon. Then we have ...

  8s = perimeter of octagon

  4(s +6) = perimeter of square

These are equal, so ...

  4(s +6) = 8s

  s +6 = 2s . . . . . . divide by 4

  6 = s . . . . . . . . . . subtract s

The octagon has 6-ft sides; the square has 12-ft sides.
