How many times does 25 go into 10,000

Answers

basically what is 10,000/25
one way to do this is
we know that 100/25=4 so
100 times x=10,000
divide by 100
x=100
100 goes into 10,000, 100 times
so therefor the answer is 4 times 100 which is 400 or


factor since
4/8=1/2 because 1/2 times 4/4=1/2 times 1/1=1/2

so 10,000=2 times 2 times 2 times 2 times 5 times 5 times 5 times 5
25=5 times 5 times 1
10000/25=(2*2*2*2*5*5*5*5)/(5*5)=(2*2*2*2*5*5)/1 times (5*5)/(5*5)=400/1 times 1/1=400
400 times!!!

Identify a number that results in a 4-digit number when 156,350 is subtracted from it

Answers

Answer:

A number is 157,355

Step-by-step explanation:

We are given a six digit number 156,350. If we subtract 156,350 from a unknown number (x) rsult should be 4 digit number.

Let we suppose 4-digit number smallest as well largest

Smallest 4-digit number = 1000

If we subtract 156,350 from x to get 1000

x-156350=1000

x=156350+1000

x=157,350

Largest 4-digit number = 9999

If we subtract 156,350 from x to get 9999

x-156350=9999

x=156350+9999

x=166,349

Four digit number should be lie between 157,350 to 166,349

We can choose any number between them

Thus, 157,355 is a number to get 4-digit number when 156,350 is subtract.

157,350 will do the job.

Math

Answers

For this question, you can find the missing side length by using the Pythagorean Theorem: c² = a² + b²

The two side lengths you are given are 5 cm and 12 cm. 
c² = 5² + 12²
c²= 25 + 144
c² = 169

Then find the square root of 169.

c= 13

Therefore the length of c is 13 cm.
