Answer:
The diameter of the circle is 
and the radius is 
Step-by-step explanation:
we know that
The circumference of a circle is equal to
where
D is the diameter of the circle
we have
substitute and solve for D
Find the radius r
-----> the radius is half the diameter
Answer:
$1,313.3 per month
Step-by-step explanation:
A=p(1+r/n)^nt
P=principal=$75,000
r=interest rate=7.2%=0.072
t=20 years
n=12 months
A=p(1+r/n)^nt
=75,000(1+0.072/12)^12*20
=75,000(1+0.006)^240
=75,000(1.006)^240
=75,000(4.2026)
=315,195
A=$315,195
The term of Lauren's loan=20 years
20 years×12 months=240 months
Lauren's pay per month =$315,195/240
=$1,313.3125
Approximately $1,313.3 per month
Answer:
6
Step-by-step explanation:
(g o f)(3) = g(f(3))
We can find f(3) using its formula with x=3:
f(3) = -2·3 +8 = -6 +8 = 2
Now, we can find g(2) using its formula with x=2:
g(2) = 3·2 = 6
So, the composition value is ...
(g o f)(3) = 6
You mean is it an irrational number?
No, it's not!
An irrational number is a number that canNOT be expressed as a fraction, and this number can be easily represented as a fraction: such as this one:
Answer:
Scientist B
Step-by-step explanation:
1 kg = 2.2 lbs
1L = 2.11 pints
So let's convert Scientist B's data.
3.0lbs salt = 3.0/2.2 = 1.36kg
6 pints water = 6/2.11 = 2.84L water
Scientist A
1kg salt
3.0L water
We now figure out the concentration of salt in water.
Scientist A Scientist B
1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L
So scientist B had a more concentrated solution.
