18 is an even number because if you divide 18 ÷ 2 = 9 it guves you an odd number
Answer:
5 centimeters
Step-by-step explanation:
We know the equation to find volume is V = B x h, where B is the base of the prism. (It is also known as the simple V = l x w x h.)
No matter what equation you use, you will end up with V = l x w x h, since the base of a rectangular prism is length x width. So, we're going to plug in our known information to get 420 = 6 x 14 x h.
Then, we're going to multiply 6 x 14 to get 84. Now we have 420 = 84 x h. To isolate the h (in order to find what it is), we must divide both sides by 84.
420/84 = 5, so whats left of the equation is 5 = h, meaning your height is 5 centimeters.
Answer:
Using the quadratic formula:
x = [-4 +- sqr root (16 - 4 * 1 * -1)] / 2 *1
x = [-4 +- sqr root (20)] / 2
x1 = [-4 + sqr root (20)] / 2
x2 = [-4 - sqr root (20)] / 2
x1 = 0.23607
x2 = -4.2361
Step-by-step explanation:
1 quarter + 1 dime + 1 nickel = 25¢ + 10¢ + 5¢ = 40¢
Each 5<span>¢ buys 15 minutes. How many ' 5</span>¢ ' are in 40<span>¢</span> ?
40/5 = 8 of them. So the (quarter+dime+nickel) can buy 8 x 15 minutes = 2 hours.
Starting at 9:00 AM, the meter had 5 minutes left on it, and Marsha bought
another 2 hours. So now the meter is good until 2 hours and 5 minutes
after 9:00 AM . . . . . 11:05 AM.
