Answer:

5 * 10^{3}.

Step-by-step explanation:

Given :  0.005

To find : How do you write 0.005 in standard form.

Solution : We have given 0.005

For standard form:

Step 1 : If a number has n digit we move decimal point ( n-1) place to left  and to balance , multiply by 10^{n-1}.

We can see we have 4 digit in 0.005.

We can write 0.005 as \frac{5}{1000}

Then 5 * 10^{3}.

Therefore,  5 * 10^{3}.

Answer:

100+25x > 350

Step-by-step explanation:

We are given the following in the question:

Keith has $100 in a savings account at the beginning of the summer.

Let x be the number of weeks he works.

He makes $25 each week at his babysitting job.

He wants to earn more than $350 dollars during summer.

Total money earned by job = 25x

His total money in account should be more than 350$.

We can write this with the help of inequality:

100+25x > 350

The following inequality represents the given situation.

Sedbober [7]

Answer:

$ 18,000 was invested at 7%, and $ 5,000 was invested at 6%.

Step-by-step explanation:

Given that I invested $ 23,000 in two accounts paying 6% and 7% annual interest, respectively, and the total interest earned for the year was $ 1,560, to determine how much was invested at each rate, the following calculation must be performed:

23,000 x 0.07 + 0 x 0.06 = 1,610

22,000 x 0.07 x 1,000 x 0.06 = 1,600

21,000 x 0.07 x 2,000 x 0.06 = 1,590

20,000 x 0.07 x 3,000 x 0.06 = 1,580

19,000 x 0.07 x 4,000 x 0.06 = 1,570

18,000 x 0.07 x 5,000 x 0.06 = 1,560

Thus, $ 18,000 was invested at 7%, and $ 5,000 was invested at 6%.

Need to be show how to solve step by step. And find a least common multiple
Firlakuza [10]
A cheap way to go about it is, use the LCD and multiply both sides by it.

now, notice the denominators, x, 4, 4x, clearly the LCD is 4x, so let's multiply both sides by that, to do away with the denominators,

\bf \cfrac{5}{x}+\cfrac{3}{4}=\cfrac{8}{4x}\implies \boxed{4x}\left(  \cfrac{5}{x}+\cfrac{3}{4} \right)=\boxed{4x}\cdot \cfrac{8}{4x}\implies 20+3x=8
\\\\\\
3x=-12\implies x=\cfrac{-12}{3}\implies x=-4

Answer:

  3, 8, 14, 30, 58

Step-by-step explanation:

As with all formulas, put the numbers in place of the corresponding variables, and do the arithmetic.

  a_1=3\qquad\text{given}\\\\a_2=8\qquad\text{given}\\\\a_3=2a_1+a_2=2(3)+8=14\\\\a_4=2a_2+a_3=2(8)+14=30\\\\a_5=2a_3+a_4=2(14)+30=58

The first 5 terms of the sequence are 3, 8, 14, 30, 58.

Ruby ate 1/5 of a pie . If there was 10 slices of pie , how many did she eat . <br> SHOW YOUR WORK
Ksju [112]

Ruby eats two slices of pie

Fraction generally represents a part of the whole. The number present in the upper side is called as numerator and the number present below is called as denominator. Fraction can also be represented as a decimal or percentage when required.

Fraction of pie Ruby ate = 1/5

Number of slices present in the pie = 10

numerical value of a fraction = fraction x total number

So, total number of slices of pie that Ruby ate = 10 x 1/5 = 2

Therefore, Ruby eats two slices of pie.

Ruby ate 1/5 of a pie and if there was 10 slices of pie, it implies Ruby eats two slices of pie.
