How can you use 1300 divided by 13 to help you find 1,287 divided 13

Mathematics

6 0

Answer:

Step-by-step explanation:

This question is about the benefits of estimation.

1300/13 is easy and results in 100.

1287/13 can be approximated by 1300/13:  1287/13 ≈ 100.

Actually, 1287 = 1300 - 13 = 13(99); just subtract 1 from 100.  

So:  1287/13 = 1300 - 13 = 1287.  A nice bit of mental math!

PLEASE HELP! FIRST AND BEST ANSWER WILL BE MARKED BRAINLIST!!<br> second sections
Vika [28.1K]

Answer:

Well, for one thing I can't read the image--it's too small!

But I know these problems well. If I am correct, this is a spinner probability problem.

Your spinner appears to have 5 sectors, all equal in area, therefore making their probability equal.

So each of those has a prob of 1/5 in the scheme of things.

To find the combonational probability below, multiply the prob of each outcome together to find each.

Have a great day, and feel free to comment with questions!

One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K−273)+32. What is the temperature in Kelvin corr
DiKsa [7]

Answer:

The temperature in Kelvin corresponding to F degrees Fahrenheit is K=\frac{F-32}{95}+273

Step-by-step explanation:

Given : One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K-273)+32.

To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?

Solution :

Temperature from Kelvin into Fahrenheit is given by,

F=95(K-273)+32

Writing Kelvin in terms of Fahrenheit,

Subtract 32 both side,

F-32=95(K-273)

Divide by 95 both side,

\frac{F-32}{95}=K-273

Add 273 both side,

\frac{F-32}{95}+273=K

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is K=\frac{F-32}{95}+273
