We are given
Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall 60 feet is 0.25(radical60).
so, time is
we have to approximate it's value
First approximation set:
we know that
we can take sqrt all the sides
we can simplify it
Divide all sides by 4
Second approximation set:
Divide all sides by 4
Third approximation set:
Divide all sides by 4
so, we get
......Answer
The two #'s are 156 and 4.
When you multiply 156*4=624.
When you add them together 156+4=160
You can also check you're work using a calculator.
Hello!
To solve this problem we first need to find the value of each given item.
12^4 is equal to 12·12·12·12, or 20,736
12·12·12·12·12 is equal to 12^5, or 248,832
With this information being provided, it can be said that 12^4 < 12x12x12x12x12
Hope this helps.
Let
x---------> represents Martin's sister's age
y--------> represents Martin's age
we know that
--------> equation
--------> equation
Substitute equation in equation
therefore
<u>the answer is</u>
Part a) An inequality that can be used to represent this situation is
or
Part b) the oldest age Martin's sister can be is years old
First One:
-5(3m+6)=-3(4m-2)
-15m-30 = -12m+6
-3m = 36
m = -12
Second:
-7(k+9)=9(k-5)-14k
-7k-63 = 9k-45-14k
-7k-63=-5k-45
-2k=18
k=-9
