Answer:

≈ 4.12 units

Step-by-step explanation:

Calculate the distance d using the distance formula

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

with (x₁, y₁ ) = (3, 8) and (x₂, y₂ ) = (- 1, 9)

d = [tex]\sqrt{(-1-3)^2+(9-8)^2}[/tex]

   = [tex]\sqrt{(-4)^2+1^2}[/tex]

   = [tex]\sqrt{16+1}[/tex]

   = [tex]\sqrt{17}[/tex]

    ≈ 4.12 ( to the nearest hundredth )

Answer:

The distance between given points is: 4.12 units

Step-by-step explanation:

Given points are:

(3, 8) and (-1, 9)

Here

[tex](x_1,y_1) = (3,8)\\(x_2,y_2) = (-1,9)[/tex]

The distance is calculated using the following formula:

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Putting the values, we get

[tex]d = \sqrt{(-1-3)^2+(9-8)^2}\\d = \sqrt{(-4)^2+(1)^2}\\d = \sqrt{16+1}\\d = \sqrt{17}\\d = 4.123105...[/tex]

Rounding off to nearest hundredth

d = 4.12 units

Hence,

The distance between given points is: 4.12 units

Answer:

12.1 meters. Hope this helped, would love brainliest!

Step-by-step explanation:

For this question we will have to try each option.

12.675+2.3=14.975 14.975+14.975+12.675+12.675=55.3 This ones not it.

25.35+2.3=28.65 28.65+28.65+25.35+25.35=108 This ones not it either.

12.1+2.3=14.4 14.4+14.4+12.1+12.1=53 THIS ONES IT!

Answer:

x = 0.1875

Step-by-step explanation:

first, you group up all of the same numbers or letters. (2x +2x)

then you solve the problem:

2x ^2 = 2x - 3

4x^2 = -3

16x = 3

16       16

x = 0.1875

Answer:

7 cookies are left out, If Amanda packs 11 boxes of cookies.

Step-by-step explanation:

Amanda has to pack cookies in boxes. The function describes how many cookies she puts in a certain number of boxes:

[tex]c=-6b+ 73[/tex]

here variable c represents number of cookies and variable b represents the number of boxes packed.

We need to find If she packs 11 boxes, how many cookies are left out.

We are given:

b = 11

We need to find c

Putting value of b and finding value of c in the equation.

[tex]c=-6b+ 73\\c=-6(11)+73\\c=-66+73\\c=7[/tex]

So, we get the value of c: c=7

Therefore,  7 cookies are left out, If Amanda packs 11 boxes of cookies.

Answer:

the answer is 0.75c

Answer:

Anil runs more by 180m.

Step-by-step explanation:

Given that:

Length of side of square park = 90 m

We will find the perimeter.

Perimeter = 4s

Perimeter = 4(90) = 360 m

Measurements of rectangular parks = length 50 m and width 40 m

Perimeter = 2(Length + Width)

Perimeter = 2(50+40) = 2(90) = 180 m

360 m > 180m

Difference = 360 - 180 = 180 m

Hence,

Anil runs more by 180m.

Y-3 = -2(x+5)

Rewrite in slope intercept form:

y-3 = -2(x+5)

Simplify the right side:

y-3 = -2x -10

Add 3 to both sides:

y = -2x -7

The y intercept is -7

Answer:

To run one lap Lin takes 1.6 minutes.

Step-by-step explanation:

To find this answer you would do 8 divided by 5. Always remember when dividing time goes first unless the instructions / directions / your teacher says differently. So, when you do 8 divided by 5 the answer you get is 1.6, and there is your answer. Also to check your answer you can do 1.6 times 5, and you get 8, so you know that 1.6 is the correct answer.

Answer:

0.57575757 / 1

Step-by-step explanation: :)

Answer:

0.5757=19/33

Explanation:

Let x=0.5757

100x=57.5757

100x−x=57.5757−0.5757=57

99x=57

x=57/99=19/33

Answer:. 30 : 48

40:64

Step-by-step explanation: The hint is in the table where the rows highlighted in pink, multiples of 5 and 8, contain the values of the original given ratio, 10:16

Equivalent ratios include any of the corresponding values in columns AND that are in the pink rows.

5:8, 10:16, 15:24, 20:32 . . .

We can see the pattern; pairs of multiples of the factors of the numbers in the original ratio are equivalent ratios.
