Answer:
Explanation:
The proportions of dimes and nickels in the withdrawls recorded by the student are:
- dimes: 12/25
- nickels: 13/25
Thus, the best prediction of the total number of dimes in the bag is found using the same ratio of dimes:
- dimes in the bag = (12/25) × 200 = 96 ← answer
Answer:
Step-by-step explanation:
1 inch = 0.0833
62 inches = x
x= 62* 0.08333
x = 5.16667
The length of the radius (r) to the nearest tenth is 13.2
<h3>What is Pythagoras theorem?</h3>
The theorem states that the square of the longest side is equal to the sum of the square of other two sides.
In order to determine the radius of the circle, we will use the theorem above to have:
AO² = AB² +r²
Given
AB = 15
AO = 20
Substitute
20² = 15² +r²
r² = 400 - 225
r² = 175
r = 13.2
Hence the length of the radius (r) to the nearest tenth is 13.2
