Snowcat [4.5K]

Answer:

$Speed = \frac{38}{3}km/hr$

Step-by-step explanation:

Given

$Distance = 3\frac{1}{6}km$

$Time = \frac{1}{4}hr$

Required

Determine the average speed

Average speed is calculated as thus;

$Speed = \frac{Distance}{Time}$

$Speed = 3\frac{1}{6}/\frac{1}{4}$

$Speed = 3\frac{1}{6} * \frac{4}{1}$

Convert Mixed Fraction to Improper fraction

$Speed = \frac{19}{6} * \frac{4}{1}$

$Speed = \frac{19 * 4}{6 * 1}$

$Speed = \frac{76}{6}$

Divide both sides of the fraction by 2

$Speed = \frac{38}{3}$

Hence:

The speed is:

$Speed = \frac{38}{3}km/hr$

Answer:

The cilinder x^{2} + y^{2} = 4 has the form x^{2} + y^{2} = r^{2}. Here, the radius of the cilinder is 2.

It is only necessary to solve the next integral by taking into account the correct limits :

$\int\limits^{2\pi}_0{} \, d\phi \int\limits^{7}_2{} \, dz \int\limits^{2}_0{r} \, dr = [2\pi -0][7 - 2][\frac{2^{2}}{2} - 0] = 10\pi$

I hope this is usefull for you

Madison went to the mall with her big sister last week and their mom drop them off at 1 o’clock and said I’ll pick you up at 2:3

DaniilM [7]

Answer:

36 minutes

Step-by-step explanation:

2/3 = 40 minutes

1/2 = 30 minutes

14/15 = 56 minutes

= 126 minutes

They were supposed to get picked up after an hour and a half, 1:00 - 2:30, which is 90 minutes. Subtract 90 from 126 because 126 is their total time out and 90 is the supposed time. Your answer is 36.
