Answer:
4x+7 = 5x-20
(reason: vertical angles are congruent; property used: distributive)
7 = 1x-20
1x = 7+20
1x = 27
x = 27
Answer:




Step-by-step explanation:
This is possible for a smaller watering can. 3 liters is about 3/4 of a gallon (imagine a jug of milk).
It is equivalent to 3000 ml, which would also be 100 ounces of water.(5 -20 oz bottles of water).
Answer:
a) Amount saved if the interest is compounded annually is $5832
b) Amount saved if the interest is compounded semi-annually is $5849.5
Step-by-step explanation:
Principal Amount P = 5000
Time t = 10 years
Annual interest i = 8% = 0.08
We need to find amount saved if interest is compounded a) annually b) semi-annually
a) Amount saved if the interest is compounded annually
If interest compounded annually, n= 1
Using Formula: 
Putting values:

So, Amount saved if the interest is compounded annually is $5832
b) Amount saved if the interest is compounded semi-annually
If interest compounded semi-annually, n= 2
Using Formula: 
Putting values:

So, Amount saved if the interest is compounded semi-annually is $5849.5
<u>Equation given</u>: 
- S: distance fallen --> 1279 ft
- t: time taken for the distance fallen
<u>Solve</u>:

Thus it took <u>8 seconds</u> for the thing to fall from the top
