Answer: By the 8th week.

Step-by-step explanation:

Let the time that matteo and luca have the same amount of money be represented by x.

The information given in the question can be formed into an equation as:

400 - 10x = 200 + 15x

Collect like terms

400 - 200 = 15x + 10x

200 = 25x

x = 200/25

x = 8

Matteo and Luca will have the same amount of money by the 8th week.

Answer:

The answer is "Please find the given plot which is shown in the figure".

Step-by-step explanation:

[tex]Minimum = 11\\\\Lower \ quartile = Q_1 = 12\\\\Median = Q_2 = 23.5\\\\Upper \ quartile = Q_3 = 27\\[/tex]

Boxes are between 12 and 27  [tex]\to Q_1 \ \ to \ \ Q_3[/tex]

The box divides a line at 23.5   [tex]\to Q2[/tex]

Step-by-step explanation:

The mean value of Keisha’s data is 1.333333.

The mean is the average of a set of variables in mathematics and statistics. There are several methods for computing the mean, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations),

We have the data,

0, 1, 0, 2, 2, 1, 3, 0, 4, 0, 1, 2.

So, the mean value of data is

= (0 +1 + 0 + 2 + 2 + 1 + 3 + 0 + 4 + 0 + 1 + 2)/12

= 16/12

= 4/3

= 1.33333

Answer:

n=5

Step-by-step explanation:

1/4(2n +6) = 4

Multiply each side by 4

4*1/4(2n +6) = 4*4

(2n +6) = 16

Subtract 6 from each side

2n+6-6 = 16-6

2n = 10

Divide each side by 2

2n/2 = 10/2

n =5

Answer:

n= 5

Step-by-step explanation:

Hello! So to find the value of n, we just multiply 1/4 by the numbers inside the parentheses and then solve for n by dividing. Let's do it!

1/4 (2n + 6) = 4

0.5n + 1.5 = 4

0.5n = 4 - 1.5

0.5n = 2.5

n = 2.5 / 0.5

n = 5

Answer:

70%

Step-by-step explanation:

The complementary angles are ∠1 and ∠5. The correct option is D.

Complementary angles are two angles whose measures add up to 90 degrees. In other words, if angle A and angle B are complementary, then:

A + B = 90 degrees

A = 90 - B

B = 90 - A

For example, if angle A measures 30 degrees, then angle B would measure 60 degrees to make a complementary pair. Complementary angles are often used in geometry and trigonometry to solve problems involving right triangles and other geometric shapes.

The two angles ∠1 and ∠5 have the sum of 90°. These angles are complementary to each other.

Answer:

y = -2x+3

Step-by-step explanation:

This is assuming you want the answer in slope-intercept (y = mx+b)

You need to know:

y = The line

m = The slope

b = The y-intercept

Step 1, replace the slope (m):

y = -2x+b

Step 2, replace the y-intercept (b):

y = -2x+3

Conclusion to 'complete the equation of the line whose slope is -2 and y intercept is (0,3)': y = -2x+3

Answer:

(x-11)^2 + (y-6)^2= 6^2

Step-by-step explanation:

Answer:

(x - 11)² + (y - 6)² = 36

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (11, 6 ) and r = 6, then

(x - 11)² + (y - 6)² = 6² , that is

(x - 11)² + (y - 6)² = 36

Answer:

(1.25, -1.5)

Step-by-step explanation:

The system of equations:

y = -2x + 1

y = -3/2

So we know that the two lines meet at the point where y = -3/2 = -1.5

∴ -1.5 = - 2x + 1

2x = 1 + 1.5 = 2.5

x = 2.5 ÷ 2 = 1.25

So the solution to this system of equation (or where the two lines meet) is the point (1.25, -1.5)

Answer:

Step-by-step explanation:

The employee earns $10,100/month, with his employer paying 1.5 times the regular rate of pay for overtime hours. To date, he has earned $124,740 during the year. He has requested that his employer withhold 12% of gross pay, which is to be contributed to a 401(k) plan. Taxable income for federal income tax withholding = $

(a) Simon's salary three years ago is $33586.576.

(b) Gross monthly salary at the present is $2798.88.

(C)  Net pay per month is $2169.09.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

The Simon's salary at present = $35730.40 p.a.

Increased rate = 6% = 0.06

(a) Simon's salary three years ago:

⇒ [tex]\$35730.40(0.06)[/tex]

⇒ [tex]\$2143.824[/tex]

Original salary of Simon,

⇒ [tex]35730.40-2143.824[/tex]

⇒ [tex]\$33586.576[/tex]

(b) Gross monthly salary at the present:

⇒ [tex]\frac{33586.57}{12}[/tex]

⇒ [tex]2798.88[/tex]

(C)  Net pay per month:

Deductions each month amount to 22.5% of his gross salary,

⇒ [tex]22.5\%=0.225[/tex]

⇒ [tex]2798.88(0.225)[/tex]

⇒ [tex]\$629.79[/tex]

Thus net pay per month,

⇒ [tex]2798.88-629.79[/tex]

⇒ [tex]\$2169.09[/tex]

Hence we can conclude that

(a) Simon's salary three years ago is $33586.576.

(b) Gross monthly salary at the present is $2798.88.

(C)  Net pay per month is $2169.09.
