**Answer:**

** .**

**Step-by-step explanation:**

Given : 105,000

To find : Rewrite 105,000 in scientific notation.

Solution : We have given 105,000 .

**Steps to write in scientific notation :
**

**
Step 1 : If a number has n digit we move decimal point ( n-1) place to left and to balance , multiply by .
**

We can see there are** n = 6** in 105,000

So, we move decimal point 5 place to the left .

Then .

**Therefore, .**

60 seconds in 1 minute.....so there is 120 seconds in 2 minutes

4 / 10 = x / 120.....4 breaths to 10 seconds = x breaths to 120 seconds

cross multiply

10x = 480

x = 480/10

x = 48 breaths <==

4 / 10 = x / 120.....4 breaths to 10 seconds = x breaths to 120 seconds

cross multiply

10x = 480

x = 480/10

x = 48 breaths <==

This data set has** zero skew as it is symmetric.**

We know that the symmetry exist in a data when the mean, median and mode of the data is same.

i.e. we are given a set of data as:

{2, 3, 2, 2, 0, 5, 2, 1, 1, 3}

- On arranging the data in increasing order we get :

0 1 1 2 **2 2** 2 3 3 5

Hence, the value that occur in the middle is: 2

Hence, we have **Median=2**

- Also, the mean is calculated as follows:

Hence,** Mean=2.1**

- Also, the mode of the data is the most frequently occurring data point in the set.

Here 2 occurs most number of times i.e. 4 times and hence we have:

**Mode=2**

Now, as the Mean, Median and Mode of the data are approximately same.

** Hence, we get the data is symmetric and hence has a zero skew.**

we know that

if two lines are perpendicular

then the product of their slopes is equal to minus one

so

in this problem we have

the value of m2 must be equal to

we know that

The formula to calculate the slope between two points is equal to

__Find the slopes of each of ordered pairs and compare with m2__

__case a) __

Substitute in the formula

The slope is equal to m2

so

The ordered pair case a) could be points on a line that is perpendicular to the given line

__case b) __

Substitute in the formula

The slope is not equal to m2

so

The ordered pair case b) could not be points on a line that is perpendicular to the given line

__case c) __

Substitute in the formula

The slope is not equal to m2

so

The ordered pair case c) could not be points on a line that is perpendicular to the given line

__case d) __

Substitute in the formula

The slope is not equal to m2

so

The ordered pair case d) could not be points on a line that is perpendicular to the given line

__case e) __

Substitute in the formula

The slope is equal to m2

so

The ordered pair case e) could be points on a line that is perpendicular to the given line

therefore

__the answer is__

The volume of a cone is

V = (1/3)πr³

We are given with radius and the height of cone, so we can solve for the radius as function of water level using ratio and proportion

3/9 = r/h

r = h/3

Substituting

V = πh³/81

Taking the derivative

dV/dt = πh²/27 dh/dt

Solving for dh/dt given

dV/dt = 10 m³/s

and

h = 3 m

dh/dt = 9.55 m/s

V = (1/3)πr³

2:25 p.m + 15 min = 2:40 p.m.

2.**He goes on a 30 minute bike ride after arriving home at 2:40 p.m. **

2:40 p.m + 30 min = 3:10 p.m.

3.**He spends 55 minutes doing homework at 3:10 p.m.**

3:10 p.m. + 55 min = 4:05 p.m.
