Step-by-step explanation:
In ten minutes she walked 1-0.5=0.5 miles.
60 minutes/10 minutes=6. So 0.5 miles ×6=3 miles per hour

-(4+h)=3h
Distribute the negative
-4-h=3h
Add like terms
-4=4h
Divide both sides by 4
-1=h
Answer: Graph is below
=============================================================
Explanation:
We divide both sides by -4 to isolate p. This will flip the inequality sign.
-16 > -4p
-16/(-4) < -4p/(-4)
4 < p
p > 4
The graph has an open hole at 4 and shading to the right. See below.
Answer and explanation:
Volume of a cylinder = π r² h
Surface area of a cylinder = 2π r h + 2π r².
Since volume of cylinder = surface area of cylinder
π r² h=2π r h + 2π r²
Solving 14)
Given height x and base 6ft, radius will be 3ft
π r² h=2π r h + 2π r²
22/7*3²*x= 2*22/7*3*x+2*22/7*3²
=22/7*9*x= 2*22/7*3*x+2*22/7*9
= 28.286x=18.857x+2*28.286
=28.286x=18.857x+56.572
=9.429x=56.572
x=5.999ft( x cannot be a negative value)
15) Given height x and base 10 m, radius will be 5m
π r² h=2π r h + 2π r²
22/7*5²*x= 2*22/7*5*x+2*22/7*5²
78.5714x= 31.429x+157.1428
47.1424x=157.1428
x=3.333m( because x cannot be negative)
