Answer:
$20.01
Step-by-step explanation:
100%-77%= 23%
They would only be paying for 23% of the original cost
$87 x 23% = $20.01

I just did this question on Edgneuity
The nonzero vector orthogonal to the plane is <-9,-8,2>.
Consider the given points are P=(0,0,1), Q=(−2,3,4), R=(−2,2,0).
The nonzero vector orthogonal to the plane through the points P,Q, and R is
Expand along row 1.
Therefore, the nonzero vector orthogonal to the plane is <-9,-8,2>.
It's - 17x trust me it's right
4.76cm
Given data
circumference= 15cm
The expression for circumference is
C= 2πr
substitute and solve for r
15= 2*3.14*r
r= 15/ 2*3.14
r=15/ 6.28
r= 2.38 cm
Hence the diameter is
D= 2r
D= 2*2.38
D=4.76cm
