Subtraction in scientific notation is pretty similar to adding, first because the exponents are the same, you can subtract 4 from 9 and =get 5 and because the exponents need to be the same, you just keep 10^10

Your final answer is 5x10^10

Hope this helped!

Find the length of the missing side Geometry
leonid [27]

7.

Since it is a right triangle we can use Pythagorean Theorem to solve.

A^2+B^2=C^2

We are given C and B. We are solving for A, so we can input what we know.

A^2+24^2=25^2

A^2+576=625

A^2=49

A=7

Therefore, the missing side is equal to 7.

12345 [234]
Per means one. So this asks for in one minute, and in one inch.
20 minutes = 6 inches.
So dividing by 20 gets you one minute.
1 minute = 6/20 inches
1 minute = 3/10 inches

20 minutes = 6 inches.
So dividing by 6 gets you one inch.
20/6 minutes = 1 inch
10/3 minutes = 1 inch

the sum of the digits of two digit number is 10. when 18 is added to the number is digit reversed find and number​
Contact [7]

Answer:

<em>The number is 46</em>

Step-by-step explanation:

<u>Equations</u>

Suppose:

a = One digit of the number

b = Tens digit of the number

The sum of the digits is 10:

a + b = 10

The number expressed as two-digits quantity is ab, and its value is

10a+b

When we add 18 to that number, we have:

10a+b+18

And that is represented as the number reversed:

10a+b+18=10b+a

Simplifying:

9a+18=9b

Dividing by 9:

a + 2 = b

Substituting in the first equation:

a + a + 2 = 10

2a = 8

a = 4

b = a + 2 = 6

Thus the number is 46

A carpenter has several boards of equal length. He cuts 3/5 of each broads.After cutting the boards the carpenter notices that h
Bess [88]

Answer:

10

Step-by-step explanation:

Length of boards are the same :

Let number of boards = x

Fraction cut from each board = 3/5

Total fraction cut = 3/5 * x

Fraction left = 1 - 3/5 = 2/5

Total fraction left = 2/5 * x

Total pieces left = 2/5 * x = 4 times length of original board

Note ; original fraction = 1

Hence,

2/5 * x = 4 * 1

2x / 5 = 4

2x = 4 * 5

2x = 20

x = 20 / 2

x = 10

Number of boards = 10
