Answer:

see explanation

Step-by-step explanation:

Using the rule of exponents

a^{m} = \frac{1}{a^{-m} } , then

2 ÷ 10^{4} = 2 ÷ \frac{1}{10^{-4} }

To divide leave first, change ÷ to × , turn second upside down

= 2 × 10^{-4}

Determina si 2018 es un termino de la siguiente progresion aritmetica 17,46,75,104,133,....
Kitty [74]
2018 is the 70th term of the progression.

Explanation
We start out finding the common difference of the progression:
46-17 = 29

Now we write the explicit formula for the sequence.  It is of the form
a_n=a_1+d(n-1)
\\
a_n=17+29(n-1)

We set this equal to 2018 to see if the answer is a whole number.  If it is, it will be the term number that gives us 2018:

2018=17+29(n-1)

Using the distributive property,
2018=17+29*n-29*1
2018=17+29n-29

Combine like terms:
2018=29n-12

Add 12 to both sides:
2018+12=29n-12+12
2030=29n

Divide both sides by 29:
2030/29=29n/29
70=n

Since n=70, this means 2018 is the 70th term of the sequence.

Mandy has six boxes of pencils each box contains 10 to the fifth power of pencils how many pencils does Mandy have
Nonamiya [84]
You have to do 10•10•10•10•10 (multiply 10, 5 times). Once you multiply 10 five times, you end up with an answer of 100,000 pencils in each box. Then since you have 6 boxes of pencils you have to multiply 100,000•6, which equals 600,000 pencils total.

Problem PageQuestion The Russell family and the Gonzalez family each used their sprinklers last summer. The water output rate fo
Agata [3.3K]

Answer: the Russell family used their sprinkler for 40 hours.

the Gonzalez family used their sprinkler for 20 hours.

Step-by-step explanation:

Let x represent the number of hours for which the Russell family used their sprinkler.

Let y represent the number of hours for which the Gonzalez family used their sprinkler.

The families used their sprinklers for a combined total of 60 hours. It means that

x + y = 60

The water output rate for the Russell family's sprinkler was 35L per hour. The water output rate for the Gonzalez family's sprinkler was 40L per hour. The total water output of both families was 2200L. It means that

35x + 40y = 2200- - - - - - - - - - --1

Substituting x = 60 - y into equation 1, it becomes.

35(60 - y) + 40y = 2200

2100 - 35y + 40y = 2200

- 35y + 40y = 2200 - 2100

5y = 100

y = 100/5

y = 20

x = 60 - y = 60 - 20

x = 40
