R = 8%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/2)((2320/2000) - 1) = 0.08
r = 0.08
Converting r decimal to R a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to get a total amount, principal plus interest, of $2,320.00 from simple interest on a principal of $2,000.00 over 2 years is 8% per year.
To calculate the answers for an expression with an absolute value term. First, we isolate the one with the absolute value.
<span>−2∣5w−7∣+9=−7
</span><span>−2∣5w−7∣=−7-9 = -16
</span>∣5w−7∣=8
<span>Then, set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.
</span>
5w=8+7
5w = 8-7
The answers are:
w = 3
w = 1/5
Answer:
224
Step-by-step explanation:
Number of trains in the roller coaster = 2
Number cars in each train = 7
Total number of cars = Number of trains 
Number of cars in each train = 
= 14
Number of people in each car = 16
Total number of people in 14 cars = Number of people in one car Number of cars = 16 14 = 224
i.e.
Total number of people in the roller coaster in one run = 224
Number of runs made by each train in one hour = 10
Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.
224 10 = <em>2240</em>
An obtuse angle is an angle with an angle measure greater than 90 degrees.
If I understood given text quite well than equation will be
4x + 3 (x+4) = -9 => 4x+3x+12=-9 => 7x=-21 => x=-21/7=-3 => x= -3
Good luck!!!
