Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect in making this statement.the statement has to at least be two sentences long. no copy from other questions like this

Answer:

A) that’s a $.30 decrease so to find the percent you do the formula

3.50x=.30

3.50x/3.50=.30/3.50

X=.0857

.0857=8.57% so$3.20 is 8.57% of $3.50

B) $3.20 markup=18.5% and $3.50 markup is 29.6% but this depends on where you round up at and you get the answer the same way, with the formula $2.70x=.80 because $3.50-$2.70 =.80

you have it right I did the work by paper and this is what I got

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ - \frac{10}{27}}}}}} [/tex]

Step-by-step explanation:

[tex] \sf{ - 3 \frac{1}{3} \div 9}[/tex]

Convert the mixed number into improper fraction

[tex] \longrightarrow{ \sf{ - \frac{ 3 \times 3 + 1}{3} \div 9}}[/tex]

[tex] \longrightarrow{ \sf{ - \frac{ 9 + 1}{3} \div 9}}[/tex]

[tex] \longrightarrow{ \sf{ - \frac{ 10}{3} \div 9}}[/tex]

Multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator

[tex] \longrightarrow{ \sf{ - \frac{ 10}{3} \times \frac{1}{9}}} [/tex]

To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator

[tex] \longrightarrow{ \sf{ - \frac{10 \times 1}{3 \times 9}}} [/tex]

[tex] \longrightarrow{ \sf{ - \frac{10}{27}}} [/tex]

Hope I helped!

Answer:

1.804

Step-by-step explanation:

In order for you to round off you need to know the place values of the numbers:

1- unit, 0- tenth, 8- hundredth, 3- thousandth, 6- ten thousandth

So you will focus on 6 and 3.

So because 6 which falls under the ten thousandth is bigger than 5 you write a 0 under it and add 1 to 3 making it 4.

Under the other numbers you do not change anything.

The answer becomes 1.804.

The 0 is just a place holder so it isn't neccessary to include it.

Multiplication Property of Equality

Step-by-step explanation:

Search Results

Featured snippet from the web

The Multiplication Property of Equality states that if you multiply both sides of an equation by the same number, the sides remain equal (i.e. equality is preserved).

There is no perfect square factor of 30 thus it cannot be simplified thus, and option (D) will be correct.

The number system is a way to represent or express numbers.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given, √30

If we could make the perfect square factor of 30 then it will come out from the radical sign as,

√12 = √(4 × 3) = √(2² × 3) = 2√3

Therefore, the √30 cannot be simplified.

Hence "There is no perfect square factor of 30 thus it cannot be simplified".

Answer

$405

Step-by-step explanation:

70% of 800 is $560

70% of 550 is $385

However, that is NOT the answer.

That is how much money is taken off the original prices.

Now:

800-560= $240

550-385= $165

240 + 165= $405

5x + 9 = 24

Subtract 9 from both sides

5x = 15

Divide both sides by 5

x = 3

Answer:

x=3

Step-by-step explanation:

5x-9=24

subract 9 from both sides and you get

5x=15 now in order to isolate the variable divide both sides by 5

Answer:

Paige, 10 3/4

Step-by-step explanation:

To figure out this problem, first you would want to get the total amount of time each girl spends on lessons. Since Paige does lessons 5 days a week for 2 1/4 each day, you would multiply 5 and 2 1/4. This equals 11 1/4 hours.

For Maggie, you would need to multiply 2 times 1/4. This equals 1/2 hours.

Paige spends more hours on lessons. She spends 10 3/4 more hours than Maggie.

Step-by-step explanation:

Factors for 20: 1, 2, 4, 5, 10, 20

Factors for 32: 1, 2, 4, 8, 16, 32

Looking at the factors, we can see that the largest factor 20 and 32 have in common is 4. The answer isn't 1 or 2 because we are looking for the greatest common factor. This means we are looking for the largest of the factors which they both share.

Factors of 45: 1 , 3 , 5 , 9 , 15 , and 45.

Factors of 75: 1 , 3 , 5 , 15 , 25 and 75

Looking at these factors, we can see that 15 is the largest factor that 45 and 75 both share. The answer is not 1, 3, or 5 because we are again looking for the GREATEST common factor.
