The answer is D
Step-by-step explanation:
Just graph it. It is actually quite easy once graphed.
Answer:
Step-by-step explanation:
A dime is worth 10 cents. Converting to dollars, it becomes 10/100 = $0.1
A quarter is worth 25 cents. Converting to dollars, it becomes 25/100 = $0.25
Let x represent the number of dimes that Jayden has.
Let y represent the number of quarters that Jayden has.
Jayden has some dimes and some quarters. He has at most 25 coins. It means that
x + y ≤ 25
The coins worth at least $4.60 combined. It means that
0.1x + 0.25y ≥ 4.6 - - - - - - - - - - 1
If Jayden has 7 dimes, then
7 + y ≤ 25
y ≤ 25 - 7
y ≤ 18
Substituting x = 7 into equation 1, it becomes
0.1 × 7 + 0.25y ≥ 4.6
0.7 + 0.25y ≥ 4.6
0.25y ≥ 4.6 - 0.7
0.25y ≥ 3.9
y ≥ 3.9/0.25
y ≥ 15.6
All possible values for the number of quarters that he could have would be
15.6 ≤ y ≤ 18

There are infinitely many numbers that can satisfy the condition given.
The only condition is that 
, once we are considering whole numbers and not integers.
Answer:
You don NOT use (10 x 10) x 2
Step-by-step explanation:
You do not use it becuase its the only one that doesnt equal 100. hope this helps :)
Answer:
r = 1.4
Step-by-step explanation:
c = Pi * D
So c = 8.8 = Pi * D
So divide both sides by Pi
so 8.8 / Pi = 2.801 = D
Radius is half the Dimeter so divide 2.801 by 2 = 1.4
