60 plain pizzas last week
42 fewer pizzas this week
Number of pizzas sold this week = 60 - 42 = 18
60 ------------------------- 100
18 ------------------------ x
x = (18 x 100)/60
x = 1800/60
x = 30%
The percent change will be 100 - 30 = 70%
Ok so 2 dice
the probability means (desired outcomes)/(total possible outcomes)
one way is to list all outcomes and find the desirable ones (I will list and find product and bold all numbers less than 13)
product of 2 numbers means multiply fyi
1,1=1
1,2=2
1,3=3
1,4=4
1,5=5
1,6=6
2,1=2
2,2=4
2,3=6
2,4=8
2,5=10
2,6=12
3,1=3
3,2=6
3,3=9
3,4=12
3,5=15
3,6=18
4,1=4
4,2=8
4,3=12
4,4=16
4,5=20
4,6=24
5,1=5
5,2=10
5,3=15
5,4=20
5,5=25
5,6=30
6,1=6
6,2=12
6,3=18
6,4=24
6,5=30
6,6=36
36 possible outcomes
23 less than 13, desired outcomes=23
probability=23/36
answer is it is 23/36 probability that the number is less than 13 aka about 64%
Circumference= 2πr
Circumference= perimeter
14.28km= 2(3.14)r
14.28= 6.2831853072r
divide both sides by 6.2831853072
2.27= r
ANSWER: The radius is 2.27km
Hope this helps! :)
