Answer:
22 and 23
Step-by-step explanation:
To find the answer, you first need to know what the value of √500 is. Using a calculator, you get an answer of 22.361....
As you can see, this number is a little bit higher than 22. The next whole number with no decimal places is 23. Therefore, your answer is 22 and 23 because the actual value of √500 lies in between these two whole numbers.
6+4+3= 13 coins
There are 20 coins so you have to subtract 20-13+7
So, Ms. Mitchell has 7 nickels in her purse
Answer:
Step-by-step explanation:
To find the length of the pole, use Pythagorean theorem,
4.6m = 4.6*100 = 460 cm
hypotenuse² = base² + altitude²
altitude² = hypotenuse² - base²
=460² - 280²
= 211600 - 78400
= 133200
altitude = √133200 = 364.97 cm
Length of the pole = 364.97 cm
b) Length of stair² = 95² + 364*94²
= 9025 + 133200
= 142225
Length of stair= √14225 = 377.13
Length of stair = 377.13 cm
If you would like to know the average rate in miles per hour, you can calculate this using the following steps:
420 miles ... 210 minutes
x miles = ? ... 1 hour = 60 minutes
420 * 60 = 210 * x
x = 420 * 60 / 210
x = 120 miles
The correct result would be 120 miles per hour.
