6. Ed drives from Jefferson to Holden, a distance of 250 miles. He then travels on to

andreev551 [17]

Answer:

The constant speed with Ed is travelling is 60 mile per hour

Step-by-step explanation:

Given as :

The distance cover to travel from Jefferson to Holden is (D1) 250 miles

The distance cover to travel from Holden to Paxton is (D2) 50 miles

Total time taken to complete entire journey = T = 5 hours

Let The constant speed of Ed = S mph

Time = $\frac{Distance}{Speed}$

Or, Time = $\frac{D1}{S}$ + $\frac{D2}{S}$

Or, 5 hour = $\frac{250}{S}$ + $\frac{50}{S}$

Or, 5 × S = 250 + 50

So, 5 × S = 300

∴ S = $\frac{300}{5}$

I.e S = 60 mph

Hence , The constant speed with Ed is travelling is 60 mile per hour Answer

A hollow sphere sits snugly in a foam cube so that the sphere touches each side of the cube. Find the volume of the foam.

ExtremeBDS [4]

Answer:

V-foam = 4r³( 2 - ----- )

Step-by-step explanation:

Let the radius of the sphere be r. Then the volume of the sphere is

V = (4/3)(π)(r³).

Next, recognize that the side length of the cube is 2r, and that the volume of the cube is thus

V = (2r)³, or 8r³.

Then the volume of the foam is equal to the volume of the cube less the volume of the sphere:

V-foam = 8r³ - (4/3)(π)(r³). This could be factored into

V-foam = 4r³( 2 - ----- )

It takes 5 minutes for 7 people to drink 25 pints of water.At this rate,how long would it take 15 people to drink 160 pints of w

EastWind [94]

Answer:

14.9 min

Step-by-step explanation:

r=rate

r25=5*7

r25=35

r=35/25

r=1.4

substitution

r160=t*15

t=time

r=1.4

1.4*160=t*15

224=t*15/15

224/15=t

14.9 min
