Have you tried asking a teacher for help before this
and did you try to take notes cuse notes are your best friends
The centre of the circle is the middle of the two endpoints
so centre M is M(1,2) so the two last options aren't valid since those would be M(1,-2) and M(-1,2)
The radius would be half the distance of the two endpoints so
√(1+2)^2+(2-1)^2
√9+1
√10
so the answer is the second one
Answer:
There are 6 nickels, 10 dimes and 13 quarters.
Step-by-step explanation:
number of nickels = n
number of dimes = n+4
number of quarters = (n+4)+3 = n+7
express total amount in cents $4.55 = 455 cents
express total in cents by multiplying quantities of coins by value and adding them up.
455 = 5*n + 10*(n+4) + 25*(n+7) 455 = 5n + 10n + 40 + 25n + 175 240 = 40n n = 6
so number of nickels = 6.
number of dimes = number of nickels + 4 = 6+4 =10
number of quarters = number of dimes + 3 = 10+3 = 13
There are 6 nickels, 10 dimes and 13 quarters.
