Answer:

10+2+0.3+0.07+0.005

Step-by-step explanation:

Writing the number in expanded form means to write the value of each digit then add them together to find the sum. For example, the number 1,234 has the following values: The value of 1 is written as 1,000 because it's in the thousands place. The value of 2 is written as 200 because it's in the hundreds place.

Answer:

1) x = 6

2) x = 4.5 or 9/2

3) x = 35

4) x = 13

Step-by-step explanation:

Question 1) Divide both sides by 3. 18 divided by 3 is 6.

Question 2) Divide both sides by 2. 9 divided by 2 is 4.5 or 9/2.

Question 3) Multiply both sides by 5. 7 times 5 is 35.

Question 4) Multiply both sides by 2. 6.5 times 2 is 13.

Answer:

($20/gal)r + ($30/gal)b ≤ $250

r + b ≤ 10 (gallons)

Step-by-step explanation:

Represent the amount of red paint by r and that of blue point by b.

Olivia must cover 5000 ft^2 with paint, which comes out to 5000/500, or 10, gallons total of red and blue paint.  The corresponding inequality is

r + b ≤ 10 (gallons)

She has onlyl $250 to spend.  Therefore, the following must hold true:

($20/gal)r + ($30/gal)b ≤ $250

The required sysstem of inequalities is thus

($20/gal)r + ($30/gal)b ≤ $250

r + b ≤ 10 (gallons)

Answer: 2. conclusion

Answer:

C

Step-by-step explanation:

Since GJ bisects ∠ FGH , then ∠ FGJ = ∠ JGH = x + 14

∠ FGH = ∠ FGJ + ∠ JGH , substitute values

4x + 16 = x + 14 + x + 14 = 2x + 28 ( subtract 2x from both sides )

2x + 16 = 28 ( subtract 16 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Thus

∠ FGJ = x + 14 = 6 + 14 = 20° → C

Answer:

30,000

Explanation:

This is less than 35000. And so we need to round the number down to the nearest ten thousand. And so if we round 34699 to the nearest ten thousand, it becomes 30000.

Answer:

35,000

Step-by-step explanation:

the explanation is that when rounding up from 34,699 it round up to

35,000 because 6 is greater than 5 which means you round up the number in front of the 5 through 9. 4 through 0. You round it to 0 so it would be 35,00.

Answer:

Total money = $30,00,000

Step-by-step explanation:

Given:

4/5 money spend on house

3/4 remaining money spend on luxury yacht

2/3 remaining money spend on trip to space

Remaining $50,000 to charity

Find:

Total money

Computation:

Assume Total money = x

So,

Spend on house = [4x/5]

Spend on luxury yacht = [x-4x/5]3/4 = 3x/20

Spend on trip to space = [x/5-3x/20]2/3 = x/30

Remaining money = x/20 - x/30 = x/60 = $50,000

So,

x/60 = $50,000

x = $300,000

Total money = $30,00,000

The money did he win is $30,00,000

Since He spends 4/5 of his money on a large house. He spends 3/4 of his remaining money on a luxury yacht. He spends 2/3 of his remaining money on a trip to space. He gives the remaining $50,000 to charity.

So,

Here we Assume Total money = x

Now

Spend on house =[tex][4x\div 5][/tex]

Spend on luxury yacht = [tex][x-4x\div 5]3\div 4 = 3x\div 20[/tex]

Spend on trip to space =[tex][x\div 5-3x\div 20]2\div 3 = x\div 30[/tex]

Remaining money [tex]= x\div 20 - x\div 30 = x\div 60[/tex] = $50,000

So,

[tex]x\div 60 = $50,000[/tex]

x = $30,00,000

Answer:

D

Step-by-step explanation:

You are subtracting two functions to get the profit, the formula is p(x)=r(x)-c(x). You know what two of those functions are equivalent to so plug it in to get

p(x)=11x-(6x+20)

to solve you must first get rid of the parentheses by distributing the negative.

p(x)=11x-6x-20

then, combine like terms (both x's)

p(x)=5x-20

That is your final answer.

Answer:

[tex]\frac{25}{144}[/tex]

Step-by-step explanation:

Given: The Hawaiian language has 12 letters: five vowels and seven consonants. A letter is randomly chosen from the bag and then replaced. Then, a second letter is randomly chosen from the bag.

To find: probability that two vowels are chosen

Solution:

Probability that a vowel is chosen = number of favourable outcomes/ Total number of outcomes

[tex]=\frac{5}{12}[/tex]

If a letter is randomly chosen from the bag and then replaced and then, a second letter is randomly chosen from the bag,

Probability that two vowels are chosen = probability that the first letter is a vowel × probability that the second letter is a vowel such that first letter is  replaced [tex]=(\frac{5}{12} )(\frac{5}{12} )[/tex]

[tex]=\frac{25}{144}[/tex]

The required probability that two vowels are chosen is 25/144. Option B is correct.

Given that,
The Hawaiian language has 12 letters: five vowels and seven consonants. Each of the 12 Hawaiian letters is written on a slip of paper and placed in the bag. A letter is randomly chosen from the bag and then replaced. Then, a second letter is randomly chosen from the bag.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Total number of sample spaces = 12
Total number of favorable outcome(5 vowel) = 5

The probability that two vowels are chosen, with proceeding replacement,
= 5 / 12 × 5 / 12
= 25/144

Thus, the required probability that two vowels are chosen is 25/144. Option B is correct.

Answer:

[tex]15 < n < 25[/tex]

Step-by-step explanation:

Given

[tex]Side\ 1 = 20cm[/tex]

[tex]Side\ 2 = 5cm[/tex]

[tex]Side\ 3 = n[/tex]

Required

Determine n using inequality

The three sides of the triangle must satisfy two of  the following conditions

[tex]Side\ 1 + Side\ 2 > Side\ 3[/tex]

[tex]Side\ 1 + Side\ 3 > Side\ 2[/tex]

[tex]Side\ 2 + Side\ 3 > Side\ 1[/tex]

Substitute values in the above inequalities;

[tex]20 + 5 > n[/tex]

[tex]20 + n > 5[/tex]

[tex]5 + n > 20[/tex]

Solve each of the inequalities

[tex]20 + 5 > n[/tex]

[tex]25 > n[/tex]

[tex]n < 25[/tex]

[tex]20 + n > 5[/tex]

[tex]n > 5 - 20[/tex]

[tex]n > -15[/tex]

[tex]5 + n > 20[/tex]

[tex]n > 20 -5[/tex]

[tex]n>15[/tex]

Since, the second inequality has negative, we simply ignore it

So, we combine the first and the third:

[tex]n>15[/tex] and [tex]n < 25[/tex]

[tex]15 < n[/tex] and [tex]n < 25[/tex]

Combine both

[tex]15 < n < 25[/tex]
