A store is making 720 limited edition watches available for sale throughout the month. Each day, 6.25% of these watches will be made available for sale.

How many watches will have been made available for sale after 5 days?

Answers

225 watches, multiply 720 by 0.0625 to get per day, then multiply by 5 for 5 days
First fine 5% of 720 which is 36
Then find 1% of 720 which is 7
Then 0.25% of 720 which is 0.75
Now add them together to find 6.25% which is equivalent to 43.75
Now times this by 5 for the 5 days
43.75 x 5 = 218.75
Now rounded up too 219 watches for sale after 5 days

In a particularly sunny month, Solaire's solar panels generated 110%, percent as much power as expected.
What fraction of the expected amount of power did Solaire's solar panels generate?

Answers

Answer:

I think the answer would be 11/10

Step-by-step explanation:

when simplifying a percent into a fraction you always make the denominator 100, since the percent is 110, the numerator is 110, so 110/100. From there you can take off the 0s from the ends of both and boom, 11/10, hope this makes sense!

Answer:

11/10 or 1 1/10

Step-by-step explanation:

110%/100% is equal to 11/10, or 1 1/10

1) Write an equation that can be used to solve for the missing angles. (5pts)

2) Then Solve the equation for find the value of X. (Make sure to explain or show all the steps to get full Credit)

Answers

I don’t know how I should find the missing angles. But I can solve for X. So first we need to combine like terms so we add 2x, x and x which gives us 4x. And we set up our problem like this: 4x + 24=180. So we then subtract 24 from 180 and get 156 then divide 4x and 156, which leaves us with x=39

The Cost C (in dollars) of making n bracelets is represented by C=45n+125. How many bracelets are made when the cost is $845?

Answers

So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.

845 = 45n + 125.

Subtract from both sides:

845-125 = 45n + 125-125

720 = 45n

Divide by 45:

720 / 45 = 45n / 45

16 = n

This means that 16 bracelets can be made if the cost is 845.

We can also re-input the information into the equation to be extra sure!

845 = 45 (16) + 125.

845 = 720 + 125.

845 = 845

Yes!

I hope this helps! :)
