There are 12 months in a year. He plans on visiting 8 times each month.
Step One
Find the number of visits per year.
<em>Givens</em>
Number of visits per month = 8
Number of months per year = 12
Visits = # visits / month * number of months
Visitis = 8 * 12
Visits = 96 visits in total.
Step Two
<em>Calculate the cost / visit</em>
Total Cost = 414 visits.
Total Visits = 96
Cost / Visit = Total Cost / Total visits.
Cost / Visit = 414 / 96
Cost / Visit = 4.31 roughly.
All the given points are collinear, so we have ...
AB +BC = AC
BC +CS +SD = BD
The problem statement tells us
BD = AC
BC +CS +SD = AB +BC . . . . . substituting for BD and AC
BC +CS +2 = 4 +BC . . . . . . . . substituting given lengths
CS = 2 . . . . . . . . . . . . . . . . . . . subtract (2+BC)
CS is the radius of Circle C, so its diameter is twice that: 4. The radius of Circle D is the diameter of Circle C plus SD, so is 4 +2 = 6. The diameter of Circle D is twice that: 12.
The diameter of Circle C is 4.
The diameter of Circle D is 12.
Answer:
10√2
Step-by-step explanation:
Lets cut the square into a triangle, making a line from one corner to another, then let's see what we have.
We shoupd have a triangle where we don't know the hypotenuse, which we can find using the formula: a^2 + b^2 = c^2
so:
10^2 + 10^2 = c^2
100 + 100 = c^2
c^2 = 200
now let's square root what we got
√200
there are 2 10's in 200, which will turn the equation to:
10√2
this can't be simplified further, so our answer is 10√2
Answer:
A.) 16/15?
B.) Idk
Step-by-step explanation:
2/3+2/5= 16/15
Simplify:
--> 1.066667
870+800=1670
Bit confusing ngl.
Answer:
49
Step-by-step explanation:
Since we are rounding to the nearest whole number we look at the tenth decimal place (the 1)
Since a one is less than 5 we keep the number the same. If it was over 5 we would round the whole number up to a 50. I hope this makes sense! Have a nice day :D
