Alborosie

There are 400 candies in the machine.

Step-by-step explanation:

Given,

Number of red candies in machine = 104

This represents 26% of the total candies.

Let,

x be the total candies in the machine.

According to statement;

26% of x = 104

$\frac{26}{100}*x=104\\0.26x=104$

Dividing both sides by 0.26

$\frac{0.26x}{0.26}=\frac{104}{0.26}\\x=400$

There are 400 candies in the machine.

Round 176,257 to the nearest hundred thousand

Luden [163]

The nearest hundred thousand would give you zeros after the comma in 176,257

If the number to the right of the comma in this case the "2" is 4 or less than you don't round the 6 up. If the "2" is 5 or greater than you round the 6 up by one number.

For example : 123,557 gives us 124,000

but 123,337 gives us 123,000

Therefore our answer is 176,000

You join an Internet service. You get the first 5 hours for free, and then you pay $2 per hour. How many hours of Internet use,

Vika [28.1K]

Answer:

Step-by-step explanation:

firstly we know we get 5 hour free so we know that when we add our total it will go up by 5. an easy way to do the equation is to take 45 and divide by two because we are essentially paying two of our 45 dollars every hour. this means that we will get half the amount we pay in hours. 45/2 =22.5 (do not round up because you will only get what you pay for and if you cant pay for a full hour you just do not get it) 22+5=27. so you get 27 hours of internet.
