Answer:
$61.18
Step-by-step explanation:
The price last week was an unknown. We will call it x. x is an entire amount, so it is 100% of x.
This week, the price is 15% lower. Since 100% - 15% = 85%, the price this week is 85% of what it was last week. Last week it was x, so this week, the price is 85% of x.
85% of x = $52
0.85x = $52
Divide both sides by 0.85:
0.85x/0.85 = $52/0.85
x = $61.1764...
Answer: $61.18
Answer:Its A or C
Step-by-step explanation:
times both sides by 2x
x(x+2)=2(4)
x²+2x=8
minus 8 both sides
x²+2x-8=0
factor
what 2 numbers multiply to -8 and add to 2
-2 and 4
(x-2)(x+4)=0
set to zero
x-2=0
x=2
x+4=0
x=-4
x=-4 and 2
Well the difference in the triangle and rectangle prism is that the equation called for 1/2 of the triangles b times h but the rectangle doesn't get divided by two so if the cross sections are equal the for the rectangle it would be v= 50(2)
of v=100

Step-by-step explanation:
Equation of a circle:
The standard equation of a circle with center 
is given by:
In which r is the radius.
Center (– 10, –3)
This means that 
. So
Passes through the point (-3,3).
This means that we use 
to find the radius squared. So
The equation of the circle is:
