Answer:

The negative numbers do not have square roots. Therefore the question does not have a solution. That is where Julie made a mistake.

Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

First, let's take a look at this property:

[tex] \displaystyle \large{ \sqrt{a} \sqrt{b} = \sqrt{ab} }[/tex]

This only works for a and b ≥ 0.

As for a & b < 0 which results in Imaginary Number, we have to convert in 'i' form.

We know that:-

[tex] \displaystyle \large{ i = \sqrt{ - 1} }[/tex]

Thus:

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{3} i \cdot \sqrt{12}i }[/tex]

Then we can multiply 12 & 3 in square root.

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36} {i}^{2} }[/tex]

We know that:

[tex] \displaystyle \large{ {i}^{2} = - 1}[/tex]

Convert i^2 to -1

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36}( - 1) } \\ \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - \sqrt{36}}[/tex]

Then evaluate √36 which is 6.

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - 6}[/tex]

Therefore the answer should be -6.

Conclusion

Julie cannot use the √a√b = √ab property first because a & b both are < 0 and the property applies for a ≥ 0, b ≥ 0.

Answer:

4

Step-by-step explanation:

Let's start with the easiest bits.

     We know the probability of drawing a red card is 1/4, this means every four cards there is one red. So, 12/4 = 3, there are 3 red cards in the 12 card pile.

    Next, we are also given the probability of drawing a blue card us 1/12. In the same fashion, we can figure out there is 1 blue card.

Finally, we are told the probability of drawing a green card is the same as drawing a yellow card. Therefore there is the same amount of green cards as yellow.

There are 8 cards left that are green or yellow, as 12 - 1 - 3 is 8. 8/2 is 4, so there are 4 green cards in the box.

Hope this helps!

Answer:

a = -88

Step-by-step explanation:

50−  a/ 11  =58

50 + -1/11 x a = 58

-1/11 x a + 50 = 58

Subtract 50 from both sides

-1/11 x a - 50 (-50) = 58 (-50)

Now multiply both sides by 11/-1

(11/-1) x (-1/11 x a) = (11/-1) x 8

a = -88

Year 1 =old price =$95

Year 2 = new price = $96.25

The inflation rate is the difference in price between two Given period :

Inflation rate :

(Change in price / old price) * 100%

((New price - old price) / old price) * 100%

((96.25 - 95) / 96) * 100%

= (1.25 / 95) * 100%

= 0.0131578 * 100%

Answer:

(5,3)

Step-by-step explanation:

Answer:

yes it is correct

Step-by-step explanation:

Answer: Yes You are correct!

Step-by-step explanation:

If a number in the tenths place is greater than or equal to 5 then we round up. Ex: 1.90 would round to 2

If a number in the tenths place is less than or equal to 4 then we round down. Ex: 1.19 would round to 1

Since 8 is in the tenths place we round up. 3.81 would be 4 rounded to the nearest whole number.

You are correct

Step 1: Solve for one of the equations for either variable.

Step 2: Substitute the expression from Step 1 into the other equation.

Step 3: Solve the resulting equation.

Step 4: Substitute the solution in Step 3 into one of the original equations to find the other variable.

Step 5: Write the solution as an ordered pair.

Step 6: Check that the ordered pair is a solution to both original equations.

The answer to the question which of these statements is correct is F. If the automobile was going 50 mph, the slope of the line is 50.

Since distance traveled in miles is graphed as a function of time in hours, this implies that distance is on the y-axis and time in hours is on the x-axis.

So, the slope of the graph is distance/time and its unit is miles/hour = miles per hour = mph.

This slope represents the speed of the automobile.

So an automobile going at 50 mph represent the slope of the line which is 50.

The answer to the question which of these statements is correct is F. If the automobile was going 50 mph, the slope of the line is 50.

Answer:

33.99

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 39.99 × 15/100

Discount = 39.99 x 0.15

You save = $6.00

Final Price = Original Price - Discount

Final Price = 39.99 - 5.9985

Final Price = $33.99

Answer:

Approximate ≈ $33.99

Step-by-step explanation:

Original: 39.99

New: x

Percent Decrease: 15%

15% of 39.99 = 0.15(39.99) = 5.9985

39.99 - 5.9985 = 33.9915 = 33.99

Answer:

The important clue here is when they say both The girls owe the same amount so what they mean is equate both the functions  

so we get

150 - 20n = 130 - 15n

Now n gives us the number of weeks so solve for n

20n - 15n = 150 - 130

5n = 20

n = 4

Now check your solution  

150-20(4) = 70

130 - 15(4) = 70

So our answer checks out after 4 weeks both girls who their dads the same amount of money .

Answer:

C: No solutions.

Step-by-step explanation:

When solving an equation and it provides a false statement, it implies that there are no values that could satisfy the given equation.  Simply put, the word "equation" in itself must provide equal values on either sides of the equal sign.

“No solution” means that there is no value, not even 0, which would satisfy the equation.

Therefore, the correct answer is C: No solutions.

Step-by-step explanation:

f(x) = 12x

since here, x>=0, the function will be continous as a linear And will have a straight lined graph

Step-by-step explanation:

given,

Harry = 3yrs

Andy = 2x ( twice as old as sam )

sam = x

their sum = 27

a/q

→ 2x + x + 3 = 27

→ 3x = 27 - 3 = 24

→ x = 24/3 = 8

→ x = 8

therefore, age of sam is 8 and Andy is 16 and Harry is 3.

the equation is

2x + x + 3 = 27

hope this answer helps you..and may u have a great day ahead!

The equation formed using the information given is x + (x + 3) + 2x = 27. Sam is 6 years old. Let x be Sam's age.

According to the given information:

1. Harry is 3 years older than Sam, so Harry's age is (x + 3) years.

2. Andy is twice as old as Sam, so Andy's age is 2x years.

3. The total of their ages is 27, so we can add their ages together and set it equal to 27:

x + (x + 3) + 2x = 27

Now, let's simplify the equation:

Combine like terms:

x + x + 3 + 2x = 27

Combine the x terms:

4x + 3 = 27

Now, we want to isolate the variable x on one side, so let's move the constant term (3) to the other side of the equation by subtracting 3 from both sides:

4x = 27 - 3

4x = 24

Finally, solve for x by dividing both sides by 4:

x = 24 / 4

x = 6

So, Sam is 6 years old.
