Answer:
- 15.4
- 567.07
- 870
- 4
- 0.78
- 72.0
Step-by-step explanation:
Locate the digit to the right of the place you're rounding to. If that digit is 5 or more, add 1 to the digit in the place you're rounding to. Drop all digits to the right of the one you're rounding to, unless it is left of the decimal point. In that case, zero any digits between the one you rounded and the decimal point. (See problem 3 for an example of this.)
If you're rounding to the ones place (nearest whole number), and that digit ends up being 0, then put a decimal point after it to indicate it is a significant digit.
The second attachment shows the names of the number places, if you need a reminder.
Use a sum or difference identity to find the exact value of cos without a calculator. to work this, we look at the 75° to see if its the sum or difference of any angles from our reference triangles.now plug in values from your reference triangles.
(n + 7) (n - 2)
n(n - 2) + 7(n - 2)
n^2 - 2n + 7n - 14
n^2 + 5n - 14
Answer:
$41.25
Step-by-step explanation:
The original price is $25. You want to sell it for 65% more. To find this amount, we need to find 65% of 25.
Let's make an equation.
65/100 • 25 = x
Multiply.
x = 16.25
Now we know how much you want to mark it up by.
Add this to your base of $25.
25 + 16.25
= 41.25
You want to sell it for $41.25.
Hope this helps!
