If the radius of mars is about 13.7% of neptune's radius, what is the radius of neptune?

1 answer:

6 0

The volumetric mean radius of Mars is about 3389.5 km. We know that it's 13.7% of Neptune's mean radius, so we can write it down as:

3389.5 = 13.7% of x (where x is Neptune's radius)
3389.5 = 13.7% x
3389.5 = 137/1000x / * 1000 (both sides)
3389500 = 137x / ÷ 137 (both sides)
x = 24740.87591240876
x ≈ 24740.88

Answer: The mean radius of Neptune is about 24740.88 km.

Wewaii [24]

Answer:

<h3> 26²/₃ liters of 15% acid and 13¹/₃ liters of 33% acid</h3>

Step-by-step explanation:

Concentration Amount of Amount

of Solution Solution (L) of Acid

15% x 0.15x

33% y 0.33y

21% 40 0.21•40

x + y = 40 ⇒ x = 40 - y

0.15x + 0.33y = 0.21•40

0.15(40 - y) + 0.33y = 0.21•40

6 - 0.15y + 0.33y = 8.4

0.18y = 2.4

y = 13¹/₃

x = 40 - 13¹/₃ = 26²/₃

This table shows the number of points two teams scored in five games

mezya [45]

Answer:

2.16

Step-by-step explanation:

The question is on mean absolute deviation

The general formula ,

Mean deviation = sum║x-μ║/N where x is the each individual value, μ is the mean and N is number of values

Team 1

Finding the mean ;

$mean= \frac{51+47+35+48+64}{5} =49$

Points Absolute Deviation from mean

51 2

47 2

35 14

48 1

64 15

Sum 34

Absolute mean deviation = 34/5= 6.8

Team 2

Finding the mean

$mean=\frac{27+55+53+38+41}{5} = 42.8$

Points Absolute deviation from the mean

27 15.8

55 12.2

53 10.2

38 4.8

41 1.8

Sum 44.8

Absolute deviation from the mean = 44.8/5 =8.96

Solution

Difference in mean absolute deviation of the two teams = 8.96-6.8 = 2.16
