I’m not to sure I was wondering the same thing
For paws charges $20.50 and woof watchers charge $15.75
Answer:
x = 3.5
Step-by-step explanation:
Triangle to the right:
4^2 + x^2 = 8^2
16 + x^2 = 64
y^2 = 48
Triangle to the left:
x^2 + 6^2 = 48
x^2 + 36 = 48
x^2 = 12
x = sqrt(12)
x = 3.5

1. Two integers with the same signs
Once 2 integers has the same sign, then just add the numbers.
For example</span>
<span>1. 1+1 = 2 </span>
<span>2. 2 + 5 = 7 </span><span>
2. Two integers with different signs
<span>When 2 integers has different sign, then find the difference
For example
1. 1-1 =0</span></span>
<span>2. 2 – 5 = -3 </span><span>
3. Two integers that vary in sign
<span>When 2 integers vary in sign, then it will depend who which number carries the largest value
For example</span></span> <span><span>
1. </span>-3 + 2 = -1</span>
<span><span>2. </span>2 – 1 = 1</span><span> </span></span>
For this case, the first thing you should do is multiply the rate of decrease by time.
We have then:
(3.6 × 10-2) * (1.8 × 104)
= 648 mm
We are going to convert this number into scientific notation:
= 6.48 * 10 ^ 2 mm
Rounding we have:
= 6.5 * 10 ^ 2 mm
Answer:
The water level in the tank decreases in 6.5 * 10 ^ 2 millimeters in 5 hours
