Answer:
BC = 6
AC = square root of 72 or 8.485...
angle A = 45
Step-by-step explanation:
BC = BA
AC^2 = BA^2 + BC^2
angle A = 180-(90+45)
Answer: -7 -2
Step-by-step explanation:-7 + -2=9 -7×-2=14
$193.50
start by multiplying 240 by .25 (25%) to find out how much is 25% of 240. this equals 60.
then, subtract $60 from $240. equals 180.
next, to add the sales tax, multiply 180 by 0.075 (7.5%) this is $13.50.
lastly, add the tax, which is $13.50, to the suit's sale price, which is $180.
180+13.5= $193.50
Answer:
Third Option
Step-by-step explanation:
We know that the function 
is defined as 
. Since the denominator is 
then we know that 
when 
We also know that the division by 0 is not defined. Therefore, the limit of 
when "x" tends to 
is infinite.
The function 
is the inverse of
By definition, if we have a function f(x), its domain will be equal to the range of its inverse function 
. If 
, then 
This also happens for the function
If when 
then when 
Then, the answer is:
(3c+s)(100-20)/100=100 multiply both sides by 100
(3c+s)80=10000 divide both sides by 80
3c+s=125 subtract 3c from both sides...
s=125-3c....now let's look at the second situation...
(4c+2s)(100-40)/100=120 multiply both sides by 100
60(4c+2s)=12000 divide both sides by 60
4c+2s=200 divide both sides 2
2c+s=100 subtract 2c from both sides
s=100-2c, and from earlier we saw that s=125-3c, since s=s:
100-2c=125-3c add 3c to both sides
100+c=125 subtract 100 from both sides
c=25, and since s=100-2c
s=50
So cds cost $25.00 and sweatshirts cost $50.00
