Answer:

$0.00851=8.51\times 10^{-3}$ cm.

Step-by-step explanation:

We have been given that the average human body cell is about $5.1\times10^{-4}$ cm in diameter. The diameter of a plant cell is $8\times10^{-3}$ cm.

To find the combined diameter of the body cell and plant cell, we will add both diameters.

First of all let us convert our given diameters in standard notation.

$5.1\times10^{-4}=0.00051$

$8\times10^{-3}=0.008$

$\text{The combined diameter of body cell and plant cell}=0.00051+0.008$

$\text{The combined diameter of body cell and plant cell}=0.00851$

Let us convert our answer in scientific notation.

$\text{The combined diameter of body cell and plant cell}=8.51\times 10^{-3}$

Therefore, the combined diameter of the body cell and plant cell is $0.00851=8.51\times 10^{-3}$ cm.

What is a 6 digit number that is divisible by 3 but not 2,4,5

chubhunter [2.5K]

Answer:

375681

Step-by-step explanation:

this number consists of 6 digits, which are divided by 3 in total. for example, 372-3+7+2=12..12:3=4 so 372 is divisible by 3

next, it's odd number

it doesn't end with 5 and it doesn't end with 0

and the last thing, it doesn't end with 2 numbers, which is divided by 4. for example, 524...24 is divided by 4, so 524 is divided too

so it may be number like

375681...3+7+5+6+8+1=30 so it's divided by 3

it isn't divided by 2 because it's odd number

isn't divided by 5, because it doesn't end with 5 or 0

and isn't divided by 4, because we can't divide 81 by 4

it can be another number, as you wish. you can create it by yourself

As a point moves in the positive x-direction along the line graphed, what is the rate of change of y with respect to x?

tatyana61 [14]

Answer:

B. 3/4

Step-by-step explanation:

Care with these types of graphs as the values are 2 rather than one on each axis.

Away from that, rate of change can also be named "slope" in which how many units up or down the y-value goes per x value. To find the slope or "rate of change" you want to use $\frac{RISE}{RUN}$ .

To find the rise over run you want to go up from any point where the x and y value line up to another. The origin or (0,0) can be used to do this. Look at point (8,6) to see this. Rise from the origin 6 times and run to the right 8 times. Rise OVER run so the rate of change can be shown as 6/8 which can be simplified to 3/4.

the length of the Boston Marathon is about 26 miles. A mile is equal to 1.609 kilometers. How many kilometers does a runner cove

Slav-nsk [51]

Answer:

41.834

Step-by-step explanation:

The complete length of the boston marathon is 26 miles

A mile is 1.609 kilometers

Therefore the number of kilometers a runner needs to run to complete the race can be calculated as follows

= 26 × 1.609

= 41.834

Hence the runner needs to run 41.834 kilometers
