Answer:
Step-by-step explanation:
This problem is just really long- it's trying to confuse you with complicated wording. Here's it demystified:
a)
t = 0 degrees Celsius
d = 1500 meters
Find the temperature, T.
b)
d = 300 meters
T = 26 degrees Celsius
Find the ground temperature, t.
NOTE: The temperatures are different! T is the final temperature and t is the ground temperature.
Answer:
1008
Step-by-step explanation:
All you have to do is find what 24 percent of 4200 is.
Remember a^(m) x a^(n) = a(m+n) & √a = a^(1/2)
===> x^(1/2 -3/2)+x(1/2 -1/2) ====> x^(-1)+x^(0) (any number Exp 0 =1)
X^(-1) +1 ===> 1/x +1 or (1+x)/x
Answer:
Her account balance will be $2,080 at the end of the year
Step-by-step explanation:
Let
y ----> Susannah's account balance
x ---> is the amount of time in months
we have

This is a linear equation in slope intercept form
where
The slope or unit rate is equal to

The y-intercept or initial value is equal to

Remember that
One year is equal to 12 months
so
For x=12 months
substitute in the linear equation
