Answer:

58.3km

Step-by-step explanation:

58300 ÷ 1000 = 58.3km

Given:-

58,300 metres

Converting to kilometers, let's do by:-

[tex] \frac{58300 \: m}{1} \times \frac{1}{1000} km[/tex]

[tex] \frac{58300}{1000} [/tex]

[tex] => 58.3 \: km[/tex]

Therefore, in kilometers, 58300 m = 58.3 km.

Answer:

Step-by-step explanation:

1) 4m + 2n = 4*7 + 2*(-2)

                 = 28 - 4

                 = 24

2) P = abc

       = 2*3*4

      =  24

3) Multiply n by 9 : 9*n = 9n

Then add 5

9n + 5

4)double of n = 2*n = 2n

Answer:

Lafayette Square is about 5688.89 square yards  

Step-by-step explanation:

The scale factor( ratio between the two sides) is 8 inches long to 4 inches wide or 2 to 1;  2 inches to one 1

Given the actual park is 160 feet wide ( need this measurement in inches).

so the actual part is 160 · 12 = 1920 inches wide.

Using the ratio long/ wide = long/ wide 2/1 = ?/1920.  The part is 3840 inches long.

Answer need to be in yards:  divide by 36 because 36 inches = 1 yard.

Long = 3840/36 = 320/3 yards

wide = 1920/36 = 160/3 yards

Actual area = L · W

                   = (320/3)·(160/3)

                   = 51200/9

                    = 5688.89 square yards  

Answer:

15.2 mph

Step-by-step explanation:

2.4÷(x+4)=1.4÷(x-4)

1.4(x+4)=2.4(x-4)

1.4x+5.6=2.4x-9.6

-x=-15.2

x=15.2

Answer:

16 * (cube root of 0.5)

Step-by-step explanation:

Radius of the big cone = 12 cm / 2 = 6 cm

Let r = radius of the small cone (cone of water), and h = the height of the small cone

Also, r / h = 6 / 16, so that h = (16/6)r = (8/3)r.

Thus, since the volume of the big cone = (1/3)π(r^2*h)=(1/3)π(6^2*16), and the volume of the small cone = (1/3)π(r^2*h)=(1/3)π(r^2*(8/3)r) = (1/3)π(r^3*(8/3)), and the volume of the small cone is half the volume of the big cone, we have that

(1/3)π(r^3*(8/3))=(1/2)((1/3)π(6^2*16))

(r^3*(8/3))=(1/2)((6^2*16))

r^3 = (3/8)(1/2)(6^2)(16)

r^3 = (1/2)(6^3)

r = (cube root of 1/2)(6),

and

h = (8/3)r = (8/3)(cube root of 1/2)(6) = 16(cube root of 1/2), the depth of the water.

Answer:

Step-by-step explanation:

circumference=75 ft.

2πr=75

r=75/2π=75/(2×3.14)≈11.937

radius=11.94 ft

Diameter=2r=2×11≈23.87 ft

Answer:

-2

Step-by-step explanation:

To find the slope pick ANY 2 points on the line and see what you had to do to get from one point to another point.

Keep in mind that slope = rise/run , or m = difference in y /difference in x

For example, Start at (0,0) and Go to (6,-3)

To get from one point to the other you have to go up 6 and left 3 so slope is

m=6/-3 = -2

Answer:

After 3 days, Noah is still farther along reading.

Step-by-step explanation:

Here are the two equations:

NN = 12tt + 41

AA = 16tt + 13

Now we plug in 3 to both equations to see what page they're on after 3 days:

[tex]NN = 12(3) + 41\\NN = 36 + 41\\NN = 77 \\\\AA = 16(3) + 13\\AA = 48 + 13\\AA = 61[/tex]

After 3 days, Noah is 77 pages along and Amelia is 61 pages along.

77 pages > 61 pages so therefore Noah is still farther along.

Answer:

y = -5x - 8

Step-by-step explanation:

Parallel lines have the same gradient

Using the point (-3,7) we will form our own equation.

-3 will be x, 7 will be y, -5 will be m, all we have to do is find the C in the form y=mx+c

7 = -5(-3) + c

7 = 15 + c

C = -8

Therefore;

y = -5x - 8

Answer:

(8, 3)

Step-by-step explanation:

The first number (8) is our x, and we can see that this point is 8 units to the right. Then the second number (3) is our y, and we can see this is 3 as the point is 3 units up.

x = right or left

      - right = positve

      - left = negative

y = up or down

      - up = positve

      - down = negative

Answer:
