Answer:

416

Step-by-step explanation:

Well I know 8 x 100=800 so I did 8 x 400=3,200

Then I added 8 x 10=80 which is 3,280

and from there I did 8 x 6=48

And then what's 3,280+48=3,328 because 3,280+40=3,320 and then add 8=3,328

Hope it helps

Answer:

If we break apart 3,328 and first divide 3,000 by 8 we get 375, and then divide 328 by 8 we get 41, this helps us understand that if we divided 3,328 by 8 we would get 416

RSM QUESTION NEED HELP!!!!!! A biker traveling at his usual speed can go from his house to work in 4 hours. When the weather is

kogti [31]

<h3>Answer: 216 miles</h3>

=======================================

Work Shown:

d = distance from work to his house

x = speed when weather is good

y = speed when weather is bad

y = x-6 since he travels 6 mph slower

------------------------

On a good weather day, he travels for 4 hours and goes at x mph

distance = rate*time

d = r*t

d = x*4

d = 4x

----------------------

On a bad weather day, he travels 4.5 hours (half hour more than 4 hrs) and goes at y = x-6 mph

d = r*t

d = y*4.5

d = 4.5y

d = 4.5(x-6) .... replace y with x-6

d = 4.5x-27 .... distribute

----------------------

The values of d for both equations are the same, as the biker is traveling the same distance. So we can equate the two right hand sides (RHS) and solve for x.

4.5x-27 = 4x

4.5x-4x = 27

0.5x = 27

x = 27/0.5

x = 54

The biker's speed on a good weather day is 54 mph.

A bad weather day's speed would be y = x-6 = 54 - 6 = 48 mph.

----------------------

Now compute the value of d

d = 4x

d = 4*54

d = 216

The biker travels 216 miles on a good weather day

or,

d = 4.5*y

d = 4.5*48

d = 216

the biker travels that same distance on a bad weather day.

Hattempt last question below, or select another question rest tenth of a percent Out of 270 racers who wanted the then, 243 comp

coldgirl [10]

Answer:

10%

Step-by-step explanation:

Given:

Total number of racers = 270

Number of racers completed the race = 243

Number of racers gave up = 20

Now,

The number of racers who did not complete the race

= Total number of racers - Number of racers completed the race

= 270 - 243

= 27

Therefore,

The percentage of racers who did not complete the race

= $\frac{\textup{number of racers who did not complete}}{\textup{Total number of racers}}\times100\%$

= $\frac{\textup{27}}{\textup{270}}\times100\%$

= 10%

In the last 2 weeks, a plant grew 1/8 in. and 3/8 in. respectively. How many inches did the plant grow in the last 2 weeks? Expr

trapecia [35]

3/8 + 1/8 = 4/8 = 1/2
therefore the plant grew 0.5 or 1/2 in.
