6 0

Step-by-step explanation:

m=(2-8)/(-5-5)=3/5

so y=(3/5)x+b.

substitute in (5,8),

8=(3/5)(5)+b

8=3+b

b=5

so y=(3/5)x+5.

a biker travel 5ft in .05seconds. At that same rate of speed , how far will the biker travel in 1minute?
Solnce55 [7]

Biker's rate is:

v = 5/0.5

v = 10 ft per sec

t = 1 min = 60 sec

d = the distance the biker travels in 1 minute

v = d/t

d = v*t

d = 10*60

d = 600 ft

The biker travels 600 feet in 1 minute

Answer:

$486

Step-by-step explanation:

First you find the area of the window. The area of a square is equal to h×w, so we take 9×9 which equals 81. Since it costs $6 per square foot, we now take 81×6, which gives us an answer of $486.

The total surface area of a cylinder is 690.8. Its diameter is 10 inches. What is it’s height?
AysviL [449]

Answer:

h=17\ in

Step-by-step explanation:

we know that

The total surface area of a cylinder is equal to

SA=2\pi r^{2}+2\pi rh

where

r is the radius of the base of cylinder

h is the height of cylinder

we have

SA=690.8\ in^2

r=10/2=5\ in ----> the radius is half the diameter

assume

\pi=3.14

substitute the given values and solve for h

690.8=2(3.14)(5^{2})+2(3.14)(5)h

690.8=157+31.4h

Solve for h

31.4h=690.8-157

31.4h=533.8

h=17\ in
