Explain how to write 50000 using exponents

Yakvenalex [24]

I think i need a bit more information but assuming if this is what you are looking for:

to write 50,000 in exponent form look for its multiples other than 1 and itself and then go from there.

This is what i general do, i pick a divisible number and keep dividing till i get to one.

50,000/2 = 25,000
25,000/5 = 5,000
5,000/10 = 500
500/10 = 50
50/10 = 5
5/5 = 1
so i divided by 2, 5,10, 10, 10, and 5 (three 10s, two 5s and one 2)

then i look if these numbers can be written in smaller divisible numbers (i.e. 10 is 2 and 5)

so 2, 5, (2,5), (2,5) ,(2,5), and 5 as you can see that cannot be divided into smaller numbers so we have thus five 5s and four 2s

therefore 50,000 = 5^5 x 2^4

hope this helps :P

(P.S. it is the best way i can explain online without a whole course on this)

Maya has to type a document of 2160 words. The graph below shows her initial progress. If

aksik [14]

The time it takes to type the document increases proportionately to the

number of words in the document.

The time it would take to type the document is; <u>36 minutes</u>

Reasons:

From the possible figure from a similar question, we have;

The points on the graph are; (0, 0), (1, 60), (2, 120), (3, 180), (4, 240)

The graph is a straight line, therefore, given that the starting point is at the origin, using the points, (0, 0), (1, 60), we have;

The slope of the graph = 60

The y-intercept = 0

The equation that represents the proportional relationship shown on the graph is therefore;

y = 60·x

Where;

y = The number of words

x = The time it takes to type the document

The time it would take Maya to type the document of 2,160 words is given as follows;

2,160 = 60·x

Therefore;

$\displaystyle Time, \ x = \frac{2,160 \ words}{60 \ words/minute} = \mathbf{36 \ minutes}$

The time it would take Maya to type the document is x = <u>36 minutes</u>

Answers:

A. 6 Large taxis = 42 seats 9 Small taxis = 36 seats = 78 seats in total

B. 6 Large taxis = $498 + 9 Small taxis = $450 498+450= $948

C. 5 Large taxis and 10 Small taxis

Step-by-step explanation:

A. 6 Large taxis = 42 seats 9 Small taxis = 36 seats = 78 seats in total

If I did 8 small taxis the total number of seats would be 74, so I did one small taxi more to make it fair. There would be seats for everyone but 3 seats extra

B. 6 Large taxis = $498 + 9 Small taxis = $450 498+450=948

C. 5 Large taxis and 10 Small taxis

While the more small taxis there are, the more cheaper it is for Max but the less seats there would be for 75 people, So I did 1 more small taxi and 1 less large taxi.

The total number of seats now is 75 seats which is perfect amount for 75 people

So the total cheaper cost would $915 while still maintaining a fair amount of seats which is 75

Seven hamburgers and four sodas cost $27.35. Four hamburgers and five sodas cost $18.75

Doss [256]

Answer:

equations:

7x + 4y = 27.35

4x + 5y = 18.75

Step-by-step explanation:

x = burgers

y = sodas

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

7x + 4y = 27.35

4x + 5y = 18.75
