((-9 - 1)/2, (-4 + 6)/2) = (-5,1)

((-5 + x)/2, (1 + y)/2) = (-4,-3)

(-5 + x)/2 = -4
-5 + x = -8
x = -3

(1 + y)/2 = -3
1 + y = -6
y = -7

Jack reads 40 pages per hour. Dave reads at the rate of 3 5 of a pages per minute. Who reads faster? By how many pages per hour

oee [108]

Given:

Number of pages read by Jack = 40 per hour

Rate of reading by Dave =3/5 of a page in a minute

To find:

The person who reads faster and by how many minutes.

Solution:

If Dave reads 3/5 of a page in a minute then in an hour he would read,

$\Rightarrow\frac{3}{5}\times60 \text{ pages }$ (60 minutes = 1 hour)

$\Rightarrow36$ pages in an hour

The difference between pages read by Jack and Dave is $40-36=4$

Therefore, Jack reads faster than Dave by 4 pages.

Solve (-4/3*pi*rˆ3*x) + (4*pi*rˆ2*y)

tangare [24]

Answer:

$(-\frac{4}{3}\pi r^3 x)+(4\pi r^2y)=4\pi r^2(-\frac{1}{3}rx+y)$

Step-by-step explanation:

$(-\frac{4}{3}\pi r^3 x)+(4\pi r^2y)\\\\=[4\pi r^2\times (-\frac{1}{3}rx)]+[4\pi r^2y]\\\\4\pi r^2\ is\ common\ in\ both\ expression\\\\ =4\pi r^2(-\frac{1}{3}rx+y)\\\\(-\frac{4}{3}\pi r^3 x)+(4\pi r^2y)=4\pi r^2(-\frac{1}{3}rx+y)$
