Answer:
1385
Step-by-step explanation:
1) the difference is d=25-8=42-25=17;
the sequence given in the condition is arithmetic one (linear relationship).
2) in order to calculate the value of the 82d term:
a(n)=a(1)+d*(n-1), where n - number of required term (it is 82), then
a(82)=8+17*(82-1)=8+1377=1385.
Answer:
Step-by-step explanation:
Step 1:
Calculate the circumference of both circles.
The formula of a circumference:of a circle with radius r:
The circle R:
The circle S:
The length of the intercepted arc for circle R is
Step 2:
Calculate what the part of the circumference of the circle R is the intercepted arc:
The same length of the circumference of the circle S is searched for the length of the intercepted arc for circle S.
Step 3:
Calculate the length of the intercepted arc for circle S:
A rectangle is a parallelogram, so it’s opposite angles are congruent and it’s consecutive angles are supplementary
Answer:
2 pounds
Step-by-step explanation:
Answer:
k = 8 + 100 (.25) - 2x
Step-by-step explanation:
Since there's a flat shipping rate, you need to first add 8.
Then you have to pay for the 100 key chains at $.25 each so you have to multiply them to get the total cost.
Next you earn 2 dollars for every key chain sold which becomes the 2x. You are then subtracting this from the amount of money you are spending to get k.
