Answer:
x=-5, y=-1
Step-by-step explanation:
Substitute x=-4+y into -2x-5y=15. So we have
-2(-4+y)-5y=15
8-2y-5y=15
-7y=7
y=-1
And x is -4+y so x= -4+(-1)= -5.
The new cost would be 1661.175 if u want it rounded it would be 1661.18 because you would need to do 1444.5 x .15 and then add that to 1444.5
Using theorem about secant segments we can write,
AB*AH=AG*AC
AC=4,
CG=6
AG=AC+CG=4+6=10
AH=3
AB= AH+HB=AH+x=3+x
(3+x)*3=10*4
9+3x=40
3x=40-9
3x=31
x=31/3≈10.3
HB≈10.3
EG=HB/2 (as radius and diameter)
EG=10.3/2≈5.2
Answer:
She needs 168 more cels to draw to complete the film sequence
Step-by-step explanation:
120 Cells in 5 seconds
You want 12 seconds.
Ratio (Proportion)
120:5
Lets find the "unit rate" of the proportion.
120/5 = 24
So the unit ratio is 24:1
Now, we can deduce to it being:
120:5
240:10
264:11
288:12
She has 120 done.
So, 288-120 = 168.
She needs 168 more cels to draw to complete the film sequence
