Answer:
20%
Step-by-step explanation:
If you see they say that the number decreased is 10% each and they say it two times. we could see that the missing number is as big as the length of two 10% together, so if you add them two you get 20%.
Step-by-step explanation:
To make it easy to read very large and small numbers, we write them in standard form. Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. 1.98 ✕ 10¹³; 0.76 ✕ 10¹³ are examples of numbers in standard form.
Answer:
24 minutes
Step-by-step explanation:
This can be explained with the equation y=2x+10 (I chose 2 arbritrary variables, any are acceptable). A week is equivalent to 7 days so x=10. Plug this into the equation and you end up with 24, because 2(7)+10=24
Answer:
![\left[\begin{array}{ccc}(-p)&--->&q\\f&t&t\\f&t&t\\t&t&f\\t&f&f\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%28-p%29%26---%3E%26q%5C%5Cf%26t%26t%5C%5Cf%26t%26t%5C%5Ct%26t%26f%5C%5Ct%26f%26f%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
First, we find all the possibilities for p and q in a table:
p q
t t
t f
f t
f f
then -p:
-p q
f t
f f
t t
t f
and we apply the operator --> (rightarrow), that is only f (false) y if the first one is t (true) and the second one is f (false)
-p ---> q
f t t
f t f
t t t
t f f
