Answer: Daniel has $22 in his savings account balance.

Step-by-step explanation:

Let Daniel's savings account balance be x

and Henry's savings account balance be y, then as given Daniel's savings account balnce is 20 times that of Henry's, We get [tex]x=20y[/tex]...........(1)

And also total amount of both savings account is $462 so we get [tex]x+y=462[/tex] ......(2)

Now by substituting values of x from (1) into (2) we get,

[tex]20y + y=462\\21y=462\\y=22[/tex]

And [tex]x=$440[/tex]

So, Daniel's savings account balance is $440

and Henry's savings account balance is $22

Answer:

Daniel have $440 in his savings account.

Step-by-step explanation:

Given that Daniel's saving account balance is 20 times the amount of Henry's savings account balance.

So, let Henry's saving account balance = x

Therefore, Daniel's saving account balance = 20 x

Given that total amount of money contained in both account is $ 462

    ⇒  20 x + x = 462

         21 x =462 ⇒ x = 22

  Hence, Daniel's saving account balance = 20 x

                                                                      = 20 * 22

                                                                     = $ 440

Answer:

[tex]18[/tex] skis and [tex]10[/tex] snowboards were rented.

Step-by-step explanation:

Let the number of skis rented be [tex]x[/tex] and the number of snowboards rented be [tex]y[/tex].

If a total of [tex]28[/tex] people rented on a certain day, then the total number of skis and snowboards rented that particular day is also [tex]28[/tex].

This gives us the equation

[tex]x+y=28...eqn(1)[/tex].

If skis cost $ [tex]16[/tex], then [tex]x[/tex] number of skis cost $ [tex]16x[/tex].

If snowboards cost $ [tex]19[/tex], then [tex]y[/tex] number of snowboards cost $ [tex]19y[/tex].

The total cost will give us another equation,

[tex]16x+19y=478...eqn(2)[/tex]

From equation (1),

[tex]y=28-x...eqn(3)[/tex].

We put equation (3) into equation (2) to get,

[tex]16x+19(28-x)=478[/tex]

We expand the brackets to obtain,

[tex]16x+532-19x=478[/tex]

We group like terms to get,

[tex]16x-19x=478-532[/tex]

This implies that,

[tex]-3x=-54[/tex]

We divide both sides by [tex]-3[/tex] to get,

[tex]x=18[/tex]

We put [tex]x=18[/tex] into equation (3) to get,

[tex]y=28-18[/tex]

[tex]y=10[/tex]

Therefore [tex]18[/tex] skis and [tex]10[/tex] snowboards were rented.

To solve this problem, you can set up a system of equations where one equation represents the total number of skis and snowboards rented, and the other represents the total cost of those rentals. By solving this system, you can determine the number of skis and snowboards rented.

This problem is a classic example of a system of linear equations. Let's denote the number of skis rented as x and the number of snowboards rented as y. From the problem, we know that:

By solving these two equations, we can find the values of x and y which represent the number of skis and snowboards rented respectively.

Final answer:

Hisaki can make 4 1/3 batches of sugar cookies with the amount of sugar he has.

Explanation:

To find out how many total batches of sugar cookies Hisaki can make, we need to divide the total amount of sugar he has (3 1/2 cups) by the amount of sugar needed for one batch (3/4 cup).

We can convert the mixed number 3 1/2 into an improper fraction: 3 1/2 = 7/2.

Now, we divide 7/2 by 3/4: (7/2) ÷ (3/4) = (7/2) x (4/3) = 28/6 = 4 2/6 = 4 1/3.

Therefore, Hisaki can make a total of 4 1/3 batches of sugar cookies with the amount of sugar he has.

Final answer:

To convert y = -3/4x - 6 to standard form with integers, multiply by 4 to remove the fraction and then arrange the equation as 3x + 4y = -24.

Explanation:

To write the equation y = -3/4x - 6 in standard form using integers, we need to rearrange the terms so that the x and y terms are on the left side of the equation and the constant is on the right side. Moreover, in standard form, the coefficients should be integers. The standard form is typically expressed as Ax + By = C.

Starting with the given equation:

y = -3/4x - 6

Multiply each term by 4 to remove the fraction:

4y = -3x - 24

Now, we need to move the x term to the left side of the equation:

3x + 4y = -24

This is the standard form of the equation, and all the coefficients are integers.

Answer:

I) P(cat│dog) = [tex]\frac{0.15}{0.38}[/tex]

II) These events are not independent

III) P(cat or dog)=  0.7

Step-by-step explanation:

Given : Households have  dogs = 38%

           So, P(dog) = 0.38

           Households have  cats = 47%

           So, P(cats) = 0.47

             Households have both dogs and cats  = 15%

           So, P(both dog and cat ) = [tex]P(cat\cap dog)[/tex] = 0.15

solution :

i) By formula P(A│B) =[tex]\frac{P(A\cap B)}{P(B)}[/tex]

P(cat│dog)= [tex]\frac{P(cat\cap dog)}{P(dog)}[/tex]

P(cat│dog) = [tex]\frac{0.15}{0.38}[/tex]

ii)  P(cat│dog)=39.47% = 0.39 and P(cat)=47% = 0.47, are the events not independent

Because condition for independent events in conditional probability is P(A|B)=P(A)

but P(cat│dog) ≠P(cat) i.e. 0.39≠0.47

So, these events are not independent

iii) P(cat or dog) = ?

"or" means union

Formula : [tex]P(A\cup B)= P(A) + P(B)-P(A\cap B)[/tex]

P(cat or dog) = [tex]P(cat\cup dog)= P(cat) + P(dog)-P(cat\cap dog)[/tex]

P(cat or dog)= 0.47 + 0.38 - 0.15

P(cat or dog)=  0.7

Step-by-step explanation:

Cats are better (sorry, I just had to say it.)

If the line MN is the angle bisector of ΔJMK, then it creates two angles of equal measure. Hence, m∠JMN is half of m∠JMK due to the property of an angle bisector.

In the field of geometry, an angle bisector is a line or ray that divides an angle into two equal angles. This is given by the information provided that MN is an angle bisector of ΔJMK.

By definition, if MN is an angle bisector of ΔJMK, then it creates two angles, ∠JMN and ∠NMK, that are equal in measure. So, we have m∠JMN = m∠NMK. This is the definition of an angle bisector, which is the reason you are looking for.

Given this, if you want to find m∠JMN in terms of ∠JMK, keep in mind that MN bisects ∠JMK, creating the two equal angles we just mentioned. Therefore, m∠JMK = m∠JMN + m∠NMK. Since ∠JMN and ∠NMK are equal, m∠JMK = 2m∠JMN. Hence, m∠JMN = 1/2m∠JMK. This would be a consequence of the angle bisector property.

Pretty sure the answer is 18-30i

Step-by-step explanation:

-30i - 18i^2

-30i - 18 x (-1)

-30i +18

The expression -6i(5+3i) simplifies to 18 - 30i in standard form of a complex number.

The problem asks us to simplify the expression -6i(5+3i). To simplify this, we multiply the complex number (-6i) with the complex number in the parenthesis. This results in (-6i * 5) + (-6i * 3i) which transforms into -30i - 18i^2. Since i^2 is -1, we can simplify further to -30i + 18. So the simplified form in standard form is 18 - 30i.

Answer: 131,400$

Step-by-step explanation:

The sale for first  month is $500.

The sale increases by $10 each month, as modelled by the equation:

a_k=500+(k-1)10

where, k = 1 (first month)

k = 2 (second month)

.... and so on.

we have to calculate the sale for the first 10 years, that means for 10*12 = 120 months (1 year = 12 months)

Total sales = ∑ a_k

∑ a_k = ∑ (500+(k-1)10)

= 500k + ∑ (10k - 10)

= 500k + 10∑k - 10k

= 490k + 10∑k

= 490k + 10 {k*(k+1)/2}

= 490k + 5{k*(k+1)}

= 490k + 5k^2 + 5k

= 5k^2 + 495k

∴∑ a_k = 5k^2 + 495k

For calculating the total sales of 10 years, we will put the value of k = 120 (120th month after the first month)

= 5*(120*120) + 495*120

= 72,000 + 59, 400

= 131,400$

Answer:

Distribute 10 to (k – 1) and simplify.

Final answer:

The new price of the item is $3 after the 85% reduction from the original price of $20.

Explanation:

To find the new price of the item after an 85% reduction, we start with the original price and calculate 85% of that price to know how much is being subtracted. The original price is $20. Now let's calculate 85% of 20 dollars:

0.85 (85%) × $20 = $17

This means an $17 reduction from the original price. We subtract this from the original price to find the new price:

$20 - $17 = $3

The new price of the item is $3 after a reduction of 85%.

In order to express the equation 5x - y = -17 in slope-intercept form (y = mx + b), we need to solve for y. After rearranging, it turns out the correct equation in slope-intercept form is y = 5x + 17.

To write the equation 5x - y = -17 in slope-intercept form, we first need to solve the equation for y. The slope-intercept form of a linear equation is y = mx + b, where m represents the slope, and b represents the y-intercept.

Let's rearrange the given equation: Start by adding 'y' to both sides to get 5x = y - 17. Add 17 to both sides, you will get y = 5x + 17. So, the correct answer is: y = 5x + 17. This aligns with option c.

Answer:

x = 7 and y = 2

Step-by-step explanation:

the denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non-zero for this value then it is a vertical asymptote

solve x - 7 = 0 ⇒ x = 7 is the asymptote

horizontal asymptotes occur as

[tex]lim( x → ± ∞), f(x) → c ( where c is a constant )

divide terms on numerator/ denominator by x

f(x) = (3/x/x/x -7/x ) + 2

as x → ± ∞, f(x) → 0 / 1 - 0 + 2 = 2

y = 2 is the asymptote

Answer: Vertical asymptote is x = 7

              Horizontal asymptote is y = 2

Step-by-step explanation:

The vertical asymptote is the restriction on the domain (x-value).  Since the denominator cannot be zero  ⇒  x - 7 ≠ 0  ⇒  x ≠ 7  so the vertical asymptote is at x = 7.

The horizontal asymptote (H.A.) is the restriction on the range (y-value). There are three rules that determine the horizontal value which compare the degree of the numerator (n) with the degree of the denominator (m):

In the given problem, n = 0 and m = 1  ⇒  n < m  ⇒  H.A. is y = 0

Since there is a vertical shift of +2 units, the H.A. is y = 0 + 2  ⇒  y = 2

Answer:

3

Step-by-step explanation:

The 'm' value stands for the slope in the context of a linear equation (y = mx + b). In the provided example, it was determined to be 3, i.e., for each unit movement along the x-axis, there will be a three units movement along the y-axis.

The

value of m

in your diagram is representative of the slope in a mathematical equation, specifically in the context of a linear equation in the form y = mx + b. Here, 'm' describes how much the line on the graph moves up or down on the y-axis along the line's length. This usually means how much 'y' changes for each one-unit change in 'x'. According to the information provided, assuming that the equation is y = mx + b and b is set to 9, the m value has been determined to be 3. This indicates that for every step you move horizontally (along the x-axis), you would move three steps vertically (along the y-axis). Hence, in this case, the value of 'm' is 3.
