Answer: In scientific notation = 8.12\times10^5 gallons of water in an olympic training center's pool.

Step-by-step explanation:

Given: 812,000 gallons of water in an olympic training center's pool.

In scientific notation ,

$812,000 =8.12\times100000=8.12\times10^5$

Scientific notation is a way to write a very large or a very small number in the product of a decimal form of number [generally between 1 and 10]and powers of ten.

Therefore,In scientific notation = 8.12\times10^5 gallons of water in an olympic training center's pool.

8.12×10^5
... i got this by taking the first number 8 and then counting the places behind the 8 which would be 5 so than you move the decimal place by 5 so you get 8.12 then you show theirs 5 places behind the 8 by adding the 10^5 so youbget 8.12×10^5

The length of the box is 2 1/2 m, it is 1 9/16 times its width. What is the height of the box if its volume is 12 3/4 m3?

Answer:

$3\frac{3}{16}$ meter

Step-by-step explanation:

We have to write first what is known from the information.

Let's say, length is L, width is W, and height is H

1. The length of the box is 2 1/2 m = 2,5 m = 5/2 m, it is 1 9/16 = 25/16 times it's width (L). So we have the equation :

L ≡ $\frac{5}{2} = \frac{25}{16} W$

Then we find the W. From the fraction above, we found W equals to $\frac{8}{5} = 1,6$ meter

2. What is the height of the box, if its volume is 12 3/4 m^3 = 51/4 m^3

Formula of a volume is :

The area wide times the height

In this problem, the equation is :

L × W × H = Volume

Insert the numbers,

$\frac{5}{2}$ × $\frac{8}{5}$ × H = $\frac{51}{4}$

From the fraction above, we can find that H equals to

$3\frac{3}{16}$ meter

F (10) = 10/2 = 5 . how to solve this problem

Sonja [21]

Answer:

f(10) means to input x = 10 into the function.

From inspection of the given function:

$\sf f(10)=\dfrac{10}{2}=5$

the "10" is the numerator of the fraction.

Therefore, swap the "10" for "x" to give the function in terms of x:

$\sf f(x)=\dfrac{x}{2}$
