d = dimes
q = quarters
d=10+q
0.25q +0.10d = 3.45
0.25q + 0.10(10+q) = 3.45
0.25q + 1 +0.10q =3.45
0.35q=2.45
q = 2.45/0.35 = 7
d = 10+7 =17
0.25*7=1.75, 17*0.10 = 1.70, 1.75+1.70 = 3.45
she has 7 quarters and 17 dimes for a total of 24 coins
Answer:
The distance between points 8 and -5 is 13
Step-by-step explanation:
We need to find distance between points 8 and -5
The formula used to find the distance is:
Absolute value is used to get only positive values. i.e |-1|=1 if required.
We are given: b=8 and a=-5
Putting values and finding distance
So, the distance between points 8 and -5 is 13
Answer:
1. 11 2. 8
Step-by-step explanation:
For number one to find the mean you would first count how many candy bars they have all together and then you would just divide by how many groups there are which since there's four people thats four groups in total they have 44 candy bars because 12+9+10+13=44 which if you divide that by 4 you get 11 as your mean.
For number two you would do the same thing count the total shoe sizes and you should get 40 and since there's 5 people which is five groups it would be 40/5 which means that the total mean would be 8.
