Answer:

29/30

Step-by-step explanation:

Converting 0.66(repeating) to fractions is using the hack of if there is a single repeating digit, put that over 9. So, 0.6666(repeating) is 6/9 or 2/3. Now, 0.3 is 3/10.

Creating a qcd(quick common denominator) we have 20/30+9/30 = 29/30, which cannot be simplified further.

PLEASE SOMEONE HELP!!!!!!!

jek_recluse [69]

The answer to this question is the second one: "In Step 2, she divided 8 by 100 instead of 100 by 8, so she cannot multiply the numerator by the factor." This is because the percentage equivalent to 1/8 is 12.5%, which you get by cross-multiplying 1/8 and ?/100. Basically, you multiply 1 with 100 (which is 100) and 8 with the unknown variable (8x). You get something that looks like 100 = 8x. Lastly, you divide 8 into both sides, which gets you 12.5. Therefore, your answer is Harriet's error is in Step 2.

<span>Here's another way to look at it.Percent means 'out of one hundred' so....think of it like this...one out of eight is how many out of 100? 1/8 = ?/100 From here you can multiply both sides by 100. On the right side, the 100 on the top will cancel the 100 on the bottom of the fraction because 100/100 = 1 and 1 times anything doesn't change that thing's value. So ?/100 times 100 = just ?On the left side of the equation, we get100 times 1/8. 100 times 1 is 100 so we're left with 100 / 8. We get the answer 12.5 percent. A double check:1 divided by 8 = .125When we substitute the 12.5 for the ? above,12.5 divided by 100 = .125
</span> 1/ 8 = 0.125 = 12.5 % / Same as converting 1/8 of a dollar to cents
First convert it to the decimal number, then Multiply by 100 ( shift decimal point twice to the right) and insert %( divide by 100) .

Between what two consecutive integers is <img src="https://tex.z-dn.net/?f=%5Csqrt182" id="TexFormula1" title="\sqrt182" alt="\s

Elden [556K]

Answer:

C. 13 and 14

Step-by-step explanation:

They notice that the square root of 182 is between 13 an 14, and it gives them the idea that the numbers 13 and 14 are the solution.

Let n be the smaller of the two consecutive integers.

Then the other integer is (n+1).

We are given that

n*(n+1) = 182.

Simplify

n^2 + n - 182 = 0,

Factor left side

(n-13)*(n+14) = 0.

The solutions are n= 13 and n= -14.

You may check that both of them satisfy the problem' condition, giving you two answers

the pair (13,14) and the pair (-14,-13).

Many people prefer to solve this problem in a short way.

They notice that the square root of 182 is between 13 an 14,

and it gives them the idea that the numbers 13 and 14 are the solution.

Then these people get the next idea that if the product of 13 and 14 is equal to 182,

then the product of the opposite numbers is also 182, so

both the pairs (13,14) and (-14,-13) are solutions.

Solved and explained in detailed and short modes.

Please help!!!! largest, and smallest 6 digit number divisible by 2,3,4,5,6,8,9,10

Vadim26 [7]

Answer:

Basically it has to be divisible by 8, 9, and 10 because any number that is divisible by 2, 3, 4, 5, 6 must also be divisible by 8, 9 and 10. We know that the number has to end in 0, the sum of its digits must be divisible by 9 and the last three digits must be divisible by 8. Therefore, the smallest number is 10080 and the largest is 999360.

Kazeer [188]

Answer:

Area = 209.5 ft² (nearest tenth)

Cost = $505 (approximated)

Step-by-step explanation:

Step 1: convert the inches to be in feet by dividing length in inches by 12.

17 feet 10 inches => $17 + \frac{10}{12} = 17.83 ft$

11 feet 9 inches => $11 + \frac{9}{12} = 11.75 ft$

Step 2: Find the area of the floor of the dinning room

Area = 17.83*11.75 = 209.5 ft² (nearest tenth)

Step 3: Find the cost of the work.

Cost = 209.5 ft² × $2.41 = $505 (approximated)
