Answer:
Step-by-step explanation:
If the baby repeats this sleep pattern until she is awakened at 6 a.m., what ... We have 10 hours between 8PM and 6AM = 10 * 60 = 600 minutes ... Awake 12:15 - 12:30 ... There are 4 periods of 2 hour sleep and 1 period of 1 hour sleep = 4*2(60) + 1(60) ... So 540/600 = 54/60 = 9/10 = 90% of the time asleep.
1. Multiply length times width as if they were integer number:
Now place the decimal point. To do it we have to keep in mind that the result will have as many decimals as the sum of the decimals of each number. In this case, only the width had one decimal, it means that the result will only have one decimal:

Answer:
x=2
Step-by-step explanation:
The axis of symmetry can be calculated using the following formula:
In order to use this formula, we need to have the function written in it's polynomial formula:
In order to do so, we have to isolate Y from the excercise's formula.
Then we resolve the square of the binomial knowing that (a+b)^2=a^2+2.a.b+b^2
Now we have that:
As we have now the polynomyal formula, we know that a=-2, b=8 and c=-13. We supplant on the formula and get:
Answer:
1) 5 ( 4h - 1 )
2) 5 ( 3r + 7 )
3) 2( -2p +5 )
Step-by-step explanation:
For no. 1 you have to find a <u>common factor (</u>a number that divides into both 20 and 5) which is 5 because 20 divided by 5 is 4 and 5 divided by 5 is 1. so you have to do 20h divided by 5 which is 4h (don't forget the h ! ) and you do -5 divided by 1 which is -1. Remember when you do any multiplying or dividing questions with negatives and positives :
minus + minus = minus (-5*-6 = -30)
positive + positive = positive (5*6 = 30) * equals multiplacation by the way
minus + positive = minus (-5*6 = -30)
positive + minus = minus (5*-6 = -30)
hope this helped xx
