Sin 40° + sin 130° + sin 220° + sin 310° = ...
sin 130° = sin 50°;
sin 220° = - sin 40°;
sin 310° = - sin 50°
... = sin 40° + sin 50° - sin 40° - sin 50° = 0
Answer: 0.
Answer:
$168
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
I=Prt
Where:
P is the principal amount, $2000.00.
r is the interest rate, 4.2% per year, or in decimal form, 4.2/100=0.042.
t is the time involved, 2....year(s) time periods.
So, t is 2....year time periods.
To find the simple interest, we multiply 2000 × 0.042 × 2 to get that:
The interest is: $168.00
1. Yes he would be able to but the back pack and he would actually have 18 to spare. Explanation- he saves $9 a week so if he saves for 7 weeks then he will have $63 but since he only needed 45 he will have 18 to spare
2. Since they have 65.50 but need to have 180 then u could just subtract 180 from 65.50 so they would 114.5 more dollars
3. Since lee scored 4 FEWER this tells us that micheal has more points so you would just add 4 to micheals total of points which would give you that micheal had 22 points
Convert milliliters to feet and then multiply 1 1/4 by 3 do the same but convert to the problems it says
Hello kiddio lets figure this out!
The formula for simple interest is I = P*R*T where I = interest, P = Principal (original amount), R is the rate as a decimal, and T is time in years. So I = 1500*(.05)*6 = 1500*(0.30) = $450. The total amount you have after 6 years is the amount you started with ($1500) plus the interest ($450) which is $1950. The formula for yearly compounding is A = P(1 + r)t where A = Accumulated or final amount P = Principal ($1500) r = interest rate as a decimal (0.05)t = time (6 years) A = 1500*(1 + 0.05)6 = 1500*(1.05)6 = $2010.14
