Complete question :

At 10:00 am, Han and Tyler both started running toward each other from opposite ends of a 10 mile path along a river. Han runs at a pace of 12 minutes per mile Tyler runs at a pace of 15 minutes per mile how far does Han run after a half hour

Answer:

2.5 miles

Step-by-step explanation:

Given :

Distance between Horn and Tyler = 10 miles

Horn's pace = 12 minutes per mile

Tyler's pace = 15 minutes per mile

Horn's distance after half an hour :

Time = Half an hour = 30 minutes

Horn's speed = distance / time

Horn's speed = 1 mile / 12 minutes = 0.83333 miles per minute

Hence, Horn's distance after half an hour :

Distance = speed * time

Distance = 0.83333 miles per minute * 30 minutes

Distance = 2.5 miles

4.3x+5x=16+7-(7)

9.3x=16

x= 1.72

give me a brainliest if possible. please.. tnx

Answer:  1.72.......

Step-by-step explanation:  4.3x + 7 + 5x = 16 + 7

=> 7 + (5x + 4.3x) = 16 + 7

7 + 9.3x = 23

9.3x = 23 - 7    [ 7 becomes -7 when transferred to RHS]

9.3x = 16

x = 16 /9.3    [ 9.3 becomes 1/9.3 when transferred to RHS]

x = 1.72......

Hope it helped u,

Answer:

Matthew does not have kids = 18%

Patrick has kids and does not Rollerblade = 4.84%

Susan Rollerblades = 93.18%  

Step-by-step explanation:

9 ÷50 = 0.18 = 18%

3÷62 ≈ 0.0484 = 4.84%

41 ÷ 44 ≈ 0.9318 = 93.18%

Answer:

The time required to  accumulate simple interest of $ 60.00

from a principal of $ 750.00  at an interest rate of 4% per year  is 2 years.

Step-by-step explanation:

Given

To determine

Time period t = ?

Using the formula

I = Prt

t = I / Pr

substitute I = $60, P = $750 and r = 0.04 in the equation

t = 60 / ( 750 × 0.04 )

t = 2  years

Therefore, the time required to  accumulate simple interest of $ 60.00

from a principal of $ 750.00  at an interest rate of 4% per year  is 2 years.

Answer:

15%

Step-by-step explanation:

First, let's find how many pounds the dog's weight increased by during the year.

80 - 64 = 16

Now, knowing that the dog's weight increased by 16 pounds, we can use that to figure out the percentage of 16 out of 64 (divide them, then multiply by 100 to get a percentage).

[tex]\frac{16}{64}[/tex] • 100 = 0.25 • 100 = 25%

Answer:

[tex] x = -2 [/tex]   or   [tex] x = -5 [/tex]

Step-by-step explanation:

You need to complete the square before you can take the square root of both sides.

[tex] x^2 + 7x + 10 = 0 [/tex]

Subtract 10 from both sides.

[tex] x^2 + 7x = -10 [/tex]

To complete the square, you need to add the square of half of the x-term coefficient to both sides.

The x-term coefficient is 7. Half of that is 7/2. Square it to get 49/4. Now we add 49/4 to both sides of the equation.

[tex] x^2 + 7x + \dfrac{49}{4} = -10 + \dfrac{49}{4} [/tex]

[tex] (x + \dfrac{7}{2})^2 = -\dfrac{40}{4} + \dfrac{49}{4} [/tex]

[tex] (x + \dfrac{7}{2})^2 = \dfrac{9}{4} [/tex]

Now we use the square root property, if

[tex] x^2 = k [/tex], then

[tex] x = \pm \sqrt{k} [/tex]

[tex] x + \dfrac{7}{2} = \pm \sqrt{\dfrac{9}{4}} [/tex]

[tex] x + \dfrac{7}{2} = \pm \dfrac{3}{2} [/tex]

[tex] x + \dfrac{7}{2} = \dfrac{3}{2} [/tex]   or   [tex] x + \dfrac{7}{2} = -\dfrac{3}{2} [/tex]

[tex] x = -\dfrac{4}{2} [/tex]   or   [tex] x = -\dfrac{10}{2} [/tex]

[tex] x = -2 [/tex]   or   [tex] x = -5 [/tex]

Answer: 1, 2, 3, 4, 6, 12

Answer:

[tex]1 \times 12 \\ 2 \times 6 \\ 3 \times 4 \\ 4 \times 3 \\ 6 \times 2 \\ 12\times1[/tex]

Answer: 12 days

Step-by-step explanation:

Divide 48 by 3 to find out how many pages she reads on in one day.

She reads 16 pages a day

Multiply 16•12 to see if the number you get will be 192

She will need 12 more days to finish her book

Given that,

Total cost function, C (x) = 43x + $1850

The revenue function R (x) = $80x

To find,

The number of units that must be produced and sold to break even.

Solution,

At break even, cost = revenue

43x + $1850 = $80x

Subtract 80x from both sides.

43x + 1850 -80x = $80x -80x

1850 = 80x-43x

37x = 1850

x = 50

So, the required number of units are 50.

Find the diagram attached

Volume of a pyramid = 1/3 * Base area * height

Base area = x*x

Base area = x²

Height = x+ 2

Get the volume:

Volume of the pyramid = 1/3 * x² * x+2

Volume of the pyramid =  x²(x+2)/3

Volume of the pyramid  = (x³+2x²)/3 cm³

Answer:

D aka (x³+2x²)/3 cm³

Answer:

3x+2, with a remainder of -6x-4

Step-by-step explanation:

Answer:

The solution set is (5,6).

Step-by-step explanation:

Given equations are:

-6x + 6y= 6         Eqn 1

-6x + 3y=-12      Eqn 2

Subtracting Eqn 2 from Eqn 1

(-6x+6y)-(-6x+3y)= 6-(-12)

-6x+6y+6x-3y=6+12

3y = 18

Dividing both sides by 3

[tex]\frac{3y}{3}=\frac{18}{3}\\y=6[/tex]

Putting y=6 in Eqn 1

-6x+6(6)=6

-6x+36=6

-6x=6-36

-6x=-30

[tex]\frac{-6x}{-6}=\frac{-30}{-6}\\x=5[/tex]

Hence,

The solution set is (5,6).

Answer:

[tex]x = - 3[/tex]

Step-by-step explanation:

[tex] - 2(3x - 2) + 2x = - 6x - 10[/tex]

[tex] = > - 6x - 4 + 2x = - 6x - 10[/tex]

[tex] = > - 4x - 4 = - 6x - 10[/tex]

[tex] = > - (4x + 4) = - (6x + 10)[/tex]

[tex] = > 4x + 4 = 6x + 10[/tex]

Keeping all like terms in L.H.S ,

[tex] = > 6x - 4x = 4 - 10[/tex]

[tex] = > 2x = - 6[/tex]

[tex] = > x = \frac{ - 6}{2} = - 3[/tex]

Answer:

V = 125.6 in³

Step-by-step explanation:

let V be volume, h the height and r the radius, then the equation relating the quantities is

V = khr² ← k is the constant of variation

To find k use the condition V = 402.12, h = 8, r = 4

402.12 = k × 8 × 4² = 128k ( divide both sides by 128 )

3.14 = k [ note 3.14 is π )

V = 3.14hr² ← equation of variation [ V = πr²h ]

Given r = 2 and h = 10, then

V = 3.14 × 10 × 2² = 3.14 × 40 = 125.6

Answer:

72 cm

Step-by-step explanation:

Relative to the first bottle, there are n - 1 spaces between the first bottle and the nth bottle. Since, each bottle is placed relative to the first bottle.

Now, for the fourth bottle, that is, n = 4, there are 4 - 1 = 3 spaces between the first and fourth bottle.

Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 3 = 36 cm.

Now, for the tenth bottle, that is, n = 10, there are 10 - 1 = 9 spaces between the first and fourth bottle.

Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 9 = 108 cm.

So, the distance between the fourth bottle and tenth bottle is distance between tenth bottle to first bottle minus distance between fourth bottle to first bottle = 108 cm - 36 cm = 72 cm
