The first pipe fills 1/8 of a pool in one hr.
The second pipe fills 1/4 of a pool in one hr.
(1/8+1/4)2= 3/4 done by the first two pipes in 2 hours.
Therefore the last pipe must do 1 1/4 of the filling in 2 hours, which is 5/8 per hour.
5/8x=1
x=8/5
It takes the third pipe 1 hour and 36 minutes to fill it by itself.
From the mean of 13,
the value of the stated summation will be given by:
(5.7-13)+(10.2-13)+(11.9-13)+(13.3-13)+(17.6-13)+(19.3-13)
=-7.3+(-2.8)+(-1.1)+0.3+4.6+6.3
=0
Hence the summation indicated also known as mean absolute deviation is 0.
Answer: C. 0
Answer:
The measure of the third side should be less than 2+5 = 7
Length of the third side<7
Hope this helps!
1pound is 800/560......which is 80/56-->10/7
so 1 pound is 10/7 dollars....
because you don't say for one dollar it is this many pounds.
also for unit rate i divide by 560 on both sides to get one pound on one side and then how many dollars on the other
Answer:
(x +9) ^2 + (y +7)^2 = 289
Step-by-step explanation:
We know the equation of a circle can be written as
(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
We are given the diameter so we can find the radius
r = d/2 = 34/2 = 17
(x- -9) ^2 + (y- -7)^2 = 17^2
(x +9) ^2 + (y +7)^2 = 17^2
(x +9) ^2 + (y +7)^2 = 289
