If 5 sips +4 gulps = 1 glass and 13 sips +7 gulps = 2 glasses, how many sips equal a gulp?

nataly862011 [7]

Answer:

3 sips equal a gulp

Step-by-step explanation:

we have

$5sips+4gulps=1glass$ ----> equation A

$13sips+7gulps=2glass$

Divide by 2 both sides

$6.5sips+3.5gulps=1glass$ ----> equation B

equate equation A and equation B

$5sips+4gulps=6.5sips+3.5gulps$

Group terms that contain the same variable

$4gulps-3.5gulps=6.5sips-5sips$

$0.5gulps=1.5sips$

$gulps=(1.5/0.5)sips$

$gulps=3sips$

therefore

3 sips equal a gulp

If the area of a circle measures 16/25 π cm2, what is the circumference of the circle in terms of π? A) 5/8 π cm B) 4/5 π cm C)

xxTIMURxx [149]

Area=pi*r^2
16/25 therefore is r^2
therefore r=4/5
circumference = 2*pi*r
8*pi/5 is the circumference, C.
