In circle O. AD and BE are diameters. The measure of arc AB is 55° and the measure of arc CD is 25° B с F D E What is the measur
klemol [59]

Answer:

100°

Step-by-step explanation:

the total of all angles around O on one side of AD is 180° (as that would represent a half-circle).

and the sum of the arc angles AB + BC + CD covers the whole 180°.

so, we have

180 = 55 + BC + 25

180 = 80 + BC

BC = 100°

The population of a town doubled every 5 years from 1960 to 1975. What is the percentage increase in population in this period ?
777dan777 [17]

Answer:

<h2>800%</h2>

Step-by-step explanation:

Let p represent the population

in 1965 → the population becomes 2p

in 1970 → the population becomes 2(2p) = 4p

in 1975 → the population becomes 2(4p) = 8p

 p  ——————> 100%

8p  ————-—-> x%

then

x=\frac{8p*100}{p}=800

Laura's uncle donated 120 cans of juice and 90 packs of cheese crackers for the school picnic. Each student is to receive the sa
liubo4ka [24]

Ok, First you have to find the GCF of 120 and 90. When I got the answer I got a GCF of 30. I got 30 by multiplying all the number prime numbers 120 and 90 had, 2×3×5=30  What I did next was  divide thirty by the number of  cracker and also by the number of can of juice.

120÷30= 4

90÷30=  3

So as you can see there could be a maximum 30 of kid's. Each of the kids would receive 4 cans of juice and 3 packs of cheese crackers.


I hope you enjoyed my explanation. :)
