Answer:
hey mate!!
Step-by-step explanation:
x^2=625
x=√625
x=25
hope it helps
The answer is $270 because the 3 in $270 is not 5 or above so you just round it to $270
1. The answer to addition problems is referred to as the sum, multiplication as the product, subtraction as the difference and division as the quotient. So...False.
2. You could turn the percent into a decimal, after rounding to 25, and multiply it by 121 to get about 30. However, I find it easier to just move the decimal one place to the left and multiply the product by how many tens are in the estimated percent.
10% = .10 .10 x 121 = 12.1 x 3 = 36.3 Which is still rather close and doesn't need a calculator.
3. Using the methods earlier, I'd say the best estimate is 45.
Hey there!
Use the pythagorean theorem:
a² + b² = c²
a will be rise and b will be run.
Distance between 9 and 2 is 7.
Distance between 3 and 0 is 3.
Plug those into the equation.
7² + 3² = c²
Square.
49 + 9 = c²
Add.
58 = c²
Square root both sides.
√58 = c
This is the distance in radical form.
Hope this helps!
