Answer:
30.3 cm
Step-by-step explanation:
Suppose the height is h after the sphere is full submerged.
4/3
R³ = r²(h-30) The volume of the sphere is equal to the volume
4/3
(10/2)³= × (14/2)²(h-30) of the water surface rising
4/3 × 125 = 49 × (h-30)
h - 30 = 49 × 3/4 × 125
h - 30 = 0.3
h = 30 + 0.3
h = 30.3 cm
Answer:
- <u><em>Option b. just below 30%</em></u>
<u><em></em></u>
Explanation:
Please, see attached the <em>histogram that represents the distribution of acceptance rates (percent accepted) among 25 business schools in 2004. </em>
<em />
The<em> median</em> is the value that separates the lower 50% from the upper 50% of the data.
Since there are 25 business schools, the middle value is the number 13.
The height of each bar is the<em> frequency</em> or number of business school for that acceptace rate:
- The first bar has frequency of 1 school
- The second bar has frequency of 3 schools: cummulative frequency: 1+3=4.
- The third bar has frequency 5 schools: cummulative frequency 4 + 5 = 9.
- The fourth bar has frequency 3 schools: cummulative frequency: 9+3=12.
Then, the 13th value is on the next bar, the fifth bar.
The fifth bar has acceptance rates 25 ≤ rate < 30.
That means that the median acceptance rate is greater than or equal to 25 and less than 30.
Thus, the choice is the option <em>b. just below 30%.</em>
A)
if 39.99 is the 100%, what is 10 in percentage? well
solve for "x".
b)
now, with the discount, the amount is 29.99, thus if 29.99 is the 100%, what is 1.95 from it in percentage?
solve for "x".
c)
the original price is 39.99, the markup on that is 60%, how much is that?
well
now, after the discount, the price is 29.99, how much is 23.994 in percentage of 29.99?
well
solve for "x".
Answer:
<em><u>Expression (19m-28) is equivalent to -4(7 - 2m) + 11m.</u></em>
Answer:
D.)
15040000 <= k <=19840000
Step-by-step explanation:
V = 1200 -0.00002k
Value V after one year falls in the range of $803.20 and $899.20.
Let's substract these values from 1200.
1200-803.20=396.80
1200-899.20=300.80
So it means that
0.00002k= 396.80
And
0.00002k= 300.80
So
0.00002k= 396.80
K= 396.80/0.00002
K= 19840000
And
0.00002k= 300.80
K = 300.80/0.00002
K= 15040000
So range is between
15040000 <= k <=19840000
