Answer:
a. Simple interest = $174
b. Compund interest = $1187.1
Step-by-step explanation:
Given the following data;
Principal, P = $1000
Interest, R = 2.9%
Time, T = 6 months
a. To find the simple interest;
S.I = (PRT)/100
S.I = (1000*2.9*6)/100
S.I = 17400/100
S.I = $174
b. To find the compound interest;
Substituting into the formula, we have;
A = $1187.1
To isolate x, we will first subtract 0.8 from both sides.
0.6x + 0.8 = 1.4
-0.8 -0.8
0.6x = 0.6
Now all we have to do is divide both sides by 0.6, because it is the number besides x.
0.6x/0.6 = 0.6/0.6
x = 1
So you get the answer of x = 1.
The first windsurfer is travelling faster. Solution:
1 meter = 3.28084 feet
The first surfer travels at 5 meters/second so you have to multiply 3.28084 by 5 which equals 16.4042 ft/second
There are 60 seconds in a minute so you will have to multiple 16.4042 ft/second by 60 seconds which equals 984.252 ft/minute
984.252 ft/minute > 720 ft/minute
Answer:
-7/6
Step-by-step explanation:
To evaluate this, start by turning each into improper fractions.
3 1/2 - 4 2/3
7/2 - 14/3
Now give both common denominators and complete the operation.
7/2 - 14/3
21/6 - 28/6
-7/6
