Answer:
7
Step-by-step explanation:
Set up a proportion
12 cookies / 2 cups = 42 cookies / x Notice that cookies are on the top and cups are on the bottom of each proportion.
12/2 = 42/x Cross multiply
12x = 84 Divide by 12
x = 84/12
x = 7
He will need 7 cups to make 42 cookies.
Answer:
Step-by-step explanation
(2/3) (60/99) = (2/99)(60/3) = (2/99)(20) = 40/99 = .040404......... So.......the sum of the first 15 digits = 7(4) + 7(0) + 0 = 28.
Answer:
59/1000
Step-by-step explanation:
Given in the question, the section will follow
<u> Event Number of employees Classification</u>
A 120 Supervisors
B 50 Maintenance
C 1460 Production
D 302 Management
E 68 Secretarial
<u>Total 2000 all employees</u>
Probability that a person selected is in maintenance
P(M)= 50/2000 =1/40
Probability that a person selected in in secretarial
P(S)=68/2000 = 17/500
The probability that the first person selected is either in maintenance or in secretarial you add the two
1/40 + 17/500 = 59/1000
Celine has already knitted 0.8 meters. Her final result should be 1.2 meters.
To calculate how many meters Celine has to knit we should subtract the alreadu knitted length of scarf from the entire length. This give the equation:\
X=1.2m-0.8m
X is the unknown
X=0.4 meters
You just need to try with all of the pair f.ex
0,-2 -> put 0 in the x-> y=8*0-2=-2 so ok it is q possible pair of the function..
You try every pair till you find set where all the pairs fit
So set 1
1 and 6: 8*1-2=6 ok
2 and 14 : 8*2-2=14 ok
Hope I could help
