Answer:
Part A.) i would say nickel and copper
Part B.) 1,034.8
Step-by-step explanation:
A.) i would say copper and nickle because they are closest in value
B.) to find the average you add all the numbers then divide them by the amount of numbers:
For example if you have 1, 3, 5 & 8
you would add 1 + 3 + 5 + 8 which equals 17
then you divide 17 by 4 which equals 4.25
Hope This Helps!!
Step-by-step explanation:
It takes Mercury approximately 58 days, 15 h, and 30 min to complete a full rotation.. We are going to write the time not in days, hours and minutes, but only hours. This means that we have to write 58 days as hours and 30 minutes as hours. 1 day is 24 hours, so 58 days are 58*24=(50+8)*(20+4)=50*20+50*4+8*20+8*4=1,000+200+160+32 =1,200+192=1,392 (hours) 60 minutes are 1 hour, so 30 minutes are 0.5 hours. Thus 58 days, 15 h, and 30 min are (1,392+15+0.5) hours = 1,407.5 hours Answer: 1,407.5 hours
This is an arithmetic sequence because each term is 9 more than the previous term, called the common difference. The equation for an arithmetic sequence is:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number...
In this case a=9 and d=9 so
a(n)=9+9(n-1)
a(n)=9+9n-9
a(n)=9n
So for any term n, a(n)=9n
...
a(16)=9*16=144
Answer:
x = 1
y = -1
Step-by-step explanation:
A*B= (4y-8 3x-3)
1-) (4×2)+(3×y)= 3y+8
2-) (4×x)+(3×(-1))= 4x-3
AB=C
(3y+8 4x-3)=(5 1)
So
3y+8=5 ; y= -3/3 = -1
4x-3=1 ; x=4/4 =1
The only way i can think of working out this question is this:
t = time p = phone calls
insert what we know:-
93 = p + 50
make P on its own:-
take away 50 from each side
43 = p
switch (you don’t HAVE to do this) :-
p = 43
So, shivani has to route a total of 43 phone calls to spend a total of 93 minutes on the phone.
