Answer: 1*18 2*9 3*6
Step-by-step explanation:
Answer:
R = 1.8229%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/4)((12875/12000) - 1) = 0.01822917
r = 0.01822917
Converting r decimal to R a percentage
R = 0.01822917 * 100 = 1.8229%/year
The interest rate required to get a total amount, principal plus interest, of $12,875.00 from simple interest on a principal of $12,000.00 over 4 years is 1.8229% per year.
Answer:
2494.756kg
*see below regarding significant digits
Step-by-step explanation:
Set up a grid to help you to know whether to divide or multiply. Stack equivalent values one on top of the other in your grid. Arrange them so that the units will cancel out. This helps you to change the units. See image.
*if you are also learning about "significant digits" then you will have to alter the answer to only include the same number of significant digits as in the question.
The exact calculated answer is 2494.756, but there are only two significant digits in the question, so the answer maybe 2500kg instead. If your teacher hasn't taught sig figs then go with the exact answer.
2494.756kg
This seems like a concept you’re going to learn and use so I’ll do a problem per section and explain.
Well basically this is a concept: if it’s a negative exponent it’s just 1/number^exponent.
So for example:
#1. 1/(10)^2 = 10^-2
The standard notation:
#9: You know that 1/(10)^3 you could either put it in a calculator or realize that you take the number 1, and move the decimal to the left three times. 0.001 would be the answer.
Scientific notation:
combines these topics. Let’s take #17. 0.025. Scientific notation means you write it as a number multiplied by 10^? So let’s see how many places you can move the decimal to get a number without the zeros.
0.025 => move it two places to the right. So that’s 2.5. Now 2.5 multiplied by what 10^? Would give you 0.025? It would be 10^-2. So your answer would be 2.5 x 10^-2.
For all of these, use your knowledge of the power of tens and dividing by tens! ^^ you got this. Let me know if you need help after this explanation.
