Answer:
True.
Explanation:
It’s true because a percent is based on decimals. For example, 0.01 is 1%, while 0.1 is 10%. So that means that 0.9 is 90%. Remember, “of” means multiplying. So, 0.9 times 133 is equal to 90% of 133.
Answer:
Cat sleeps 420 hours than Alice in a month
Step-by-step explanation:
Given:
Number of hours Alice sleeps per night = 9 hours
Number of hours Cat sleeps per night = 20 hours
To Find:
How many more hours does a cat sleep in 1 month that Alice
Solution:
Let
The total number of hours for which Alice Sleeps in one month be x
The total number of hours for which Cat sleeps in one month be y
Step 1: Number of hours for which Alice Sleeps in one month
X = number of days in a month X Number of hours Alice sleeps per night
X = 30 X 9
X = 180 Hours
Step 2: Number of hours for which Cat Sleeps in one month
y= number of days in a month X Number of hours cat sleeps per night
y = 30 X 20
y = 600 Hours
Now ,
=> y – x
=>600 – 180
=>420 hours
Answer:
{-2,4,8}
Step-by-step explanation:
The range of a function represents all of the y-values.
In this case, you have y-values of (-2,4,-2, 8)
Since it hasn't been stated whether the function is continuous or not, we can just assume the function only has values at those points.
Thus the range is {-2,4,8}
