3 that’s the answer your welcome
The first is the right one
t(x)=-5x+3
t(-1)=-5*(-1)+3=5+3=8
s(x)=3x-4
s(t(-1))=s(8)=3*8-4=24-4=20
answer is 20
Answer:
13/20 lbs
Step-by-step explanation:
1/4 lbs screws + 2/5 lbs nails
We need to get a common denominator
That would be 20
1/4 *5/5 + 2/5 *4/4
5/20 + 8/20
13/20 lbs
Answer:
A = 64 pi unit^2
Step-by-step explanation:
Circumference is given by
C = 2 * pi *r
16 pi = 2 * pi *r
Divide each side by pi
16 = 2r
Divide by 2
16/2 = 2r/2
8 = r
Now we can find the area
Area is equal to
A = pi r^2
A = pi (8)^2
A = 64 pi unit^2
