7. kelly and leigh are serving cupcakes in common grounds. if they arrange the cupcakes
in groups of 2, 3, or 5 they always have one left over. what is the smallest number of
cupcakes they could have? (hint: list the possible number of cupcakes given that
grouping them in twos results in one left over. then do the same for groupings of 3 and
5.)

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

they used 313 gallons of paint
