Answer:
$100
Step-by-step explanation:
Given data
Principal = 500
Interest= 5%
Time = 4years
Applying the simple interest expression
SI= PRT/100
substitute
SI= 500*5*4/100
SI= 10000/100
SI= 100
Hence the interest after 4 years is $100
Answer:
81/4
Step-by-step explanation:
By the Pythagorean theorem, the length of the altitude drawn from the hypotenuse is
This means that by the geometric mean theorem, that out of the two segments the hypotenuse is split into, the one with unknown length has length 65/4.
Thus, x = 65/4 + 4 = 81/4.
Answer:
The expression a^b
means that we multiplicate the number a by itself b times.
So x^2 means that we multiplicate the number x by itself 2 times:
x^2 = x*x
and 2^x means that we multiplicate the number 2 by itself x times
2^x = 2*2*2*....*2 (if you count them, you should see x times the number 2)
for example, if x = 4, we will have
2^4 = 2*2*2*2
Given :
Ruben put an empty cup underneath a leaking faucet.
After 1 ½ hours, Ruben had collected ¼ cup of water.
To Find :
The rate, in cups per hour, at which the water is leaking from the faucet.
Solution :
Rate in which cup is filling with water.
Therefore, the rate is 0.167 cup/hour.
