Step-by-step explanation:
Find the square root of the number and if it’s even and there’s no decimal than it’s a perfect square
Answer:
x = 13 1/2 days
Step-by-step explanation:
1/2 acre 2 1/4 acre
------------ = -------------------------
3 days x days
using cross products
1/2 * x = 2 1/4 * 3
change 2 1/4 to an improper fraction (4*2+1)/4 =9/4
1/2 x = 9/4*3
1/2x = 27/4
multiply each side by 2
2 * 1/2 x = 27/4 * 2
x = 27/2
change back to a mixed number
x = 13 1/2
Answer:
169 quarters
Step-by-step explanation:
Recall that 1 quarter = 25 pennies, and so the conversion factor is
1 quarter
-------------------
25 pennies
Use this conversion factor to convert 4246 pennies into quarters:
1 quarter
------------------- * 4246 pennies = 169.84
25 pennies
Obviously we cannot get our hands on 0.84 quarters, so round the above result down:
4246 pennies = 169 quarters plus 21 leftover pennies.
Answer:
6.36 Divided by 50 eqauls 0.1272
Step-by-step explanation:
Answer:
Therefore the probability that a pen from the first box and a crayon from the second box are selected is 
Step-by-step explanation:
Probability:
The ratio of the number of favorable outcomes to the number all possible outcomes of the event.

Given that,
Three plain pencils and 5 pens are contained by the first box.
Total number of pens and pencils is =(3+5)=8
The probability that a pen is selected from the first box is
=P(A)


A second box contains three colored pencils and three crayons.
Total number of pencils and crayons is =(3+3)=6
The probability that a crayon is selected from the second box is
=P(B)


Since both events are mutually independent.
The required probability is multiple of the events
Therefore the required probability is
