Answer:

Step-by-step explanation:

Given that Renee jogs 2.5 miles 4 days of a week,

Her total distance in a week = distance × number of days

                                         = 2.5 × 4

                                         = 10

Renee jogs a total of 10 miles in a week.

The place value of 2 is unit and 5 is tenths, so Renee jogs for 2 unit and 5 tenths of miles 4 day in a week.

Her total distance in a week = 2 unit 5 tenths + 2 unit 5 tenths+ 2 unit 5 tenths + 2 unit 5 tenths

But,

5 tenths + 5 tenths + 5 tenths + 5 tenths = 2 unit

2 unit + 2 unit + 2 unit + 2 unit = 8 unit

Her total distance in a week = 8 unit + 2 unit

                                               = 10

Her total distance in a week is 10 miles.

The length of a room is 2 times it's breadth and 5 times of it's height.If the volume of the room is 800 m cube find the cost of
Anit [1.1K]

The length of a room is 2 times it's breadth and 5 times of it's height.If the volume of the room is 800 m cube find the cost of papering it's wall at rs 6 per m²

Answer:

Rs. 1440

Step-by-step explanation:

Given that:

Breadth = b

Length = 2b

Height = 2b/5

Volume = b * 2b * 2b/5

Volume = 800 m³

800 = b * 2b * 2b/5

800 * 5 = 4b³

4000 = 4b³

4000/4 = 4b³/4

1000 = b³

10³ = b³

b = 10m

Length = 2 * 10 = 20m

Height = (2 * 10) / 5 = 4m

If plastering is at Rs. 6 per m²

Surface area:

2(lenght + breadth) height

2(20 + 10)4

2(30)4 = 240m²

Rs. 6 * 240 = Rs. 1440

Allison owns a trucking company. For every truck that goes out, Allison must pay the
Vinvika [58]

Answer:

x = 11

Step-by-step explanation:

well you take the base equation 11*x + 1*x = 286

( x being hours and y being the number of miles)

then you put in the numbers of the question it gives you 11x + 15x = 286 then you should add 11x and 15x together because they have the same variable which gives you 26x = 286 then you divide 286/26 so that you get x = 11

James is the manager at an entertainment arena that draws an average 7,000 patrons per event. Each ticket taker can process 350
Elina [12.6K]

Answer:

No. James didn't have enough ticket takers to process the average number of patrons hat usually attend the events.

He need to hire 2 more ticket taker (i.e 20 ticket takers) in order to process the average number of patrons hat usually attend the events.

Step-by-step explanation:

Given:

Average amount of patron per event= 7000

Each ticket taker can process = 350

Number of ticket takers hired = 18

We need to find the whether he hire enough to process the average number of patrons that usually attend the events.

Solution:

We will find the Average amount of patron ticket takers can process.

Now we can say that

Average amount of patron ticket takers can process is equal to Each ticket taker can process multiplied by Number of ticket takers hired.

framing in equation form we get;

Average amount of patron ticket takers can process = 350 \times 18 = 6300\ patrons

Hence With the required hires James cannot fully process the patrons usually attending the event.

To find how many ticket takers required we will divide average number of patrons with  Each ticket taker can process.

framing in equation form we get;

ticket takers required = \frac{7000}{350}=20

hence In order t process the the average number of patrons that usually attend the events James will require 20 ticket takers.

What is the sum of the infinite geometric series?<br><br> mc010-1.jpg
ra1l [238]
You haven't provided the series, therefore, I can only help with the concept.

<u><em>For an infinite geometric series, we have two possibilities for the common ratio (r):</em></u>
for r > 1, the terms in the series will keep increasing infinitely and the only possible logic summation of the series would be infinity
for r < 1, the terms will decrease, therefore, we can formulate a rule to get the sum of the infinite series

<u><em>In an infinite series with r < 1, the summation can be found using the following rule:</em></u>
sum = \frac{a_{1} }{1-r}
where:
a₁ is the first term in the series
r is the common ratio

<u>Example:</u>
For the series:
2 , 1, 0.5 , 0.25 , ....
we have:
a₁ = 2
r = 0.5
Therefre:
sum = \frac{2}{1-0.5} = 4

Hope this helps :)
