Answer:

1/4

Step-by-step explanation:

Absolute values are always positive.

The absolute value is |1/4|

To understand this let's first understand the definition of absolute value.

Absolute value - The non-negative value of a number without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.

Therefore the absolute value of -1/4 is just 1/4.

Also, remember that to indicate that it's the absolute value you have to add a " | " before and after the number. Like this |1/4|

Answer:

y= -6x +1

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx +c, where m is the gradient (or slope) and c is the y-intercept.

In order to find the equation of a line, you would need 2 things:

① Gradient (← can be found)

② Coordinate (✓ we have 2 coordinates here)

To find the gradient, use the gradient formula below:

[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]

[tex]m = \frac{ - 5 - ( - 17)}{1 - 3} \\ m = \frac{ - 5 + 17}{ - 2} \\ m = \frac{12}{ - 2} \\ m = - 6[/tex]

Substitute the value of m into the equation:

y= -6x +c

To find the value of c, substitute a pair of coordinates.

When x=1, y= -5,

-5= -6(1) +c

c -6= -5

c= 6 -5

c= 1

Thus, the equation of the line is y= -6x +1.

Answer:

a). The number if ways it can be arranged in a row= 362880 ways

b). 40320 ways

c). 5040 ways

Step-by-step explanation:

There are 9 alphabets in the word ALGORITHM

The number if ways it can be arranged in a row= 9!

The number if ways it can be arranged in a row= 9*8*7*6*5*4*3*2*1

The number if ways it can be arranged in a row= 362880 ways

if A and L must remain together (in order) as a unit, then we take it as 8 alphabets

= 8!

= 8*7*6*5*4*3*2*1

= 40320 ways

if the letters GOR must remain together (in order) as a unit, then we have 7 alphabets units remaining

= 7!

= 7*6*5*4*3*2*1

= 5040 ways

a). The number of ways it can be arranged in a row= 362880 ways.

b) The number of ways should be 40320 ways.

c) The number of ways should be 5040 ways.

a. Since There are 9 alphabets in the word ALGORITHM

So, The number of ways it can be arranged in a row= 9!

[tex]= 9*8*7*6*5*4*3*2*1[/tex]

= 362880 ways

b. In the case when  A and L must remain together (in order) as a unit, then we take it as 8 alphabets

= 8!

[tex]= 8*7*6*5*4*3*2*1[/tex]

= 40320 ways

c. In the case when the letters GOR must remain together (in order) as a unit, so we have 7 alphabets units remaining

= 7!

[tex]= 7*6*5*4*3*2*1[/tex]

= 5040 ways

The answer is Day 3. The blue bar for day 3 is the tallest, which means that was the highest amount.

On day 3 the sharpest boost in accumulated tips. Therefore, option C is the correct answer.

Given that, the graph shows Marc's individual and cumulative tips for 7 days.

We need to find which day gave Marc the sharpest boost in accumulated tips.

Bar graphs are the pictorial representation of data (generally grouped), in the form of vertical or horizontal rectangular bars, where the length of bars is proportional to the measure of data. They are also known as bar charts. Bar graphs are one of the means of data handling in statistics.

Now, in the given graph we can see that on day 3 tip is more.

On day 3 the sharpest boost in accumulated tips. Therefore, option C is the correct answer.

Answer:

-125 dollars.

Step-by-step explanation:

When dealing with negatives, the smaller the numerical number (remember, with the negative attached), the greater the number.

Meaning, -1 will be greater than -100.

In this case, Elise has an account balance of -$115, or that she owes $115.

Look at each answer choice:

$0: In this case, it means that Elise paid the bank back $115, and that she has a zero balance account. She neither has money nor owes any.

-$115: In this case, it means that she owes $115.This means that there was no change to the balance.

-$105: In this case, it means that she owes $105. Since this is $10 less than the amount she previously owed, it means that she paid $10 into the bank account.

-$125: In this case, it means that she owes $125. Since this is $10 more than the amount she previously owed, it means she overdrew once again, or was charged for failing to pay. This is your answer choice.

Answer:

x = -10

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

8x - 2(x + 1) = 7x + 8

Step 2: Distribute

8x - 2x - 2 = 7x + 8

Step 3: Combine like terms

6x - 2 = 7x + 8

Step 4: Subtract 6x on both sides

-2 = x + 8

Step 5: Subtract 8 on both sides

-10 = x

Step 6: Rewrite

x = -10

Multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, ...

The two digit numbers in that list above all have their digits adding to some other multiple of 3

and so on.

Therefore, the rule is: If the digits add to a multiple of 3, then the original number is a multiple of 3.

Answer:

Step-by-step explanation:

Let the original price be x

The discounted price for a clearance sale = 30% of x

If the price tag after discounting = $199.

Using the relationship to find the original price x

Original price - discounted price = Current price tag after discounting

x - 0.3x = 199

0.7x = 199

Divide both sides by 0.7

0.7x/0.7 = 199/0.7

x = $284.29

Hence the suit's original price is approximately $284.29

Step-by-step explanation:

Determine the possible distance of ship A from the boat

The distress is represented by X;

So, the question requires we calculate distance AX;

This will be done using cosine formula as follows;

[tex]a^2 = b^2 + x^2 - 2bxCosA[/tex]

In this case;

a = 70;

b = ??

x = 120

A = 28 degrees

Substitute these values in the formula above

[tex]70^2 = b^2 + 120^2 - 2 * b * 120 Cos28[/tex]

[tex]4900 = b^2 + 14400 - 2 * b * 120 * 0.8829[/tex]

[tex]4900 = b^2 + 14400 - 211.9b[/tex]

Subtract 4900 from both sides

[tex]b^2 + 14400 - 4900 - 211.9b = 0[/tex]

[tex]b^2 + 9500 - 211.9b = 0[/tex]

[tex]b^2 - 211.9b + 9500 = 0[/tex]

Solve using quadratic formula

[tex]\frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]

Substitute 1 for a; -211.9 for b and 9500 for c

[tex]b = \frac{-(211.9)\±\sqrt{(211.9)^2 - 4 * 1 * 9500}}{2 * 1}[/tex]

[tex]b = \frac{211.9\±\sqrt{44901.61 - 38000}}{2}[/tex]

[tex]b = \frac{211.9\±\sqrt{6901.61}}{2}[/tex]

[tex]b = \frac{211.9\±83.08}{2}[/tex]

This can be splitted to

[tex]b = \frac{211.9+83.08}{2}[/tex]  or    [tex]b = \frac{211.9-83.08}{2}[/tex]

[tex]b = \frac{294.98}{2}[/tex]   or  [tex]b = \frac{128.82}{2}[/tex]

[tex]b = 147.49[/tex]   or   [tex]b = 64.41[/tex]

[tex]b = 147.5km\ or\ b = 64.4km[/tex]

Hence, the two possible distance are 147.5km and 64.4km

Step-by-step explanation:

If you have two marbles in a bag and you are choosing the marbles randomly twice, then we can look at fractions.

Each time, you have a 0.5 chance of picking the silver marble. After you pick that, you have another 0.5 chance of picking the silver marble again.

This applies with any combination.

This means that the probability of you getting two silvers in a row is 0.25.

Since the marbles are the same size and nothing is stopping you from choosing one, this probability applies to all combinations possible.

Answer:

width=16

length=38

Step-by-step explanation:

perimeter of a rectangle=2(length+width)

108/2=length+ width

54=length+ width

54-width=length

also:

length-6= 2×width

length=2width +6

now you can put the length we found, in the second equation:

54-width=2width+6

54-6=2width+width

48=3width

width=16

now do the exact same thing with one of the equations we created in the beginning.

either this:

54-width=length

or this:

length=2width +6

as the 1st one is simpler, I use that:

54-(16)=length

length=38

One Solution

Step-by-step explanation:

So we have the equation:

[tex]4x+(-3x+2)=2x+5-2[/tex]

On both sides, combine like terms:

[tex](4x-3x)+2=2x+(5-2)[/tex]

Simplify:

[tex]x+2=2x+3[/tex]

Subtract x from both sides. The left cancels:

[tex](x+2)-x=(2x+3)-x\\2=x+3[/tex]

Subtract 3 from both sides. The right cancels:

[tex](2)-3=(x+3)-3\\-1=x[/tex]

Flip:

[tex]x=-1[/tex]

So, our equation only has one solution.

And the answer is -1 :)
