Answer:
-0.5°C every hour
Step-by-step explanation:as the temperature of the bottom of the mountain changed at 1/5 the rate of temperatures change on the top of the mountain, so, the hourly rate of temperature change at the bottom of the mountain is=
-2.5×(1/5)
=-0.5
Answer:
28.3 (explaination below)! :)
Step-by-step explanation:
Use the formula for cicrumfrence: C=2πr
Radius can be found by splitting the given number in half, (unless you were given the radius already, then you'd just multiply by 2).
Plug in our numbers. C= 2π4.5
Then, multiply.
You'd get 28.27433388230814.
Rounding to the first decimal place, you'd have a final answer of 28.3.
Hope this helps!
Answer: a. They can find the present value of the remaining 20 years worth of payments.
Step-by-step explanation:
The present value of the payments for the servicing of the loan is the amount of the loan that is still owed because the payments include both the interest and the principal repayments.
The Schmidts can therefore find out the amount they still owe by checking the present value of the remaining 20 years worth of payments.
As the payments are usually constant they can be treated as an annuity so using the monthly payment as the annuity, the interest rate as the discount rate and the 20 years ( 240 months) as the period, they should be able to find the present value of the loan.
Answer:
a ">"
Step-by-step explanation:
3 to the power negative one (-1) is the same as 1/3 (one unit divided by 3).
1/4 on the other hand is one unit divided by 4.
Dividing one object into three parts (think for example a chocolate bar) gives you a larger (greater) piece than dividing it into four equal pieces.
Therefore 1/3 > 1/4
Answer: idk if there’s any specific choice, but it should be the case.
Step-by-step explanation:
if n^2 is divisible by 3, n must also be divisible by three, since its squaring n by itself. probably a bad explanation. 3^2 is 9, 9^2 is 81, 12^144. all of them are divisible by three. Basically think of it as: 9^2 is (3x3)^2. 12 is (3x4)^2. So if n^2 is divisible by 3, n should also be divisible by 3. Sorry for the bad explanation. also I hope it’s right, sorry if it’s wrong.
