Answer:
Step-by-step explanation:
<h3>Part B</h3>
Assumed the dimensions of the top and bottom parts are identical.
Since the cylindrical part has total height of 1.8 cm and the hemisphere volume is transferred to bottom part and the cone part is still full, the value of h is the difference of the total height of cylinder and full part of the top section of cylinder:
- h = 1.8 cm - 0.3 cm = 1.5 cm
<h3>Part C</h3>
Find the volume of sand in the bottom part. It consists of a hemisphere and a cylinder of 1.5 cm height.
- V(cylinder) = πr²h = 3.14*(2.6/2)²*1.5 ≈ 7.96 cm³
- V(hemisphere) = 2/3πr³ = 2/3*3.14*(2.6/2)³ ≈ 4.6 cm³
<u>Total sand in the bottom part:</u>
<u>Time taken:</u>
- 12.56 / 0.05 = 251.2 seconds = 4 min 11.2 seconds
Answer: There are 152 apples.
The explanation is shown below:
- You need to write the following three equations, where
is the the number of apples,
is the number of pears and
is the number of oranges:
1) 
2) 
3) 
- You must substitute the equation 3) into the equation 2):

- Now, you need to solve for
in the equation 1) and then you must substitute it into
:


- Solve for
, as following:

- Therefore, there are 152 apples.
Answer:The answer is 183, hope I helped.
Answer:
okay so, i had a problem like this one and hated it, so ill try to help you out here
Step-by-step explanation:
If it is 81 all together it is safe to say the length and width is nine, making one mat six by 3, the little square being 3 by 3,
so the area of one mat would be six times three = 18
and if the width is 3, the length would be 6, unless it is cut in half, which we can assume it is not.
I hope this helps!
Answer:
0.80
Step-by-step explanation:
The z-score is found from the formula ...
Z = (X -μ)/σ
Z = (77 -73)/5 = 4/5 = 0.80
Jennifer's Z-score was 0.80.
