a) KJL = 76⁰

b) LKM = 76/2 = 38⁰

Answer:

∠KJL = 76°

∠LKM = 38°

Step-by-step explanation:

since arc KL = 76°, ∠KJL also = 76° because central angles are congruent to their arcs.

∠LKM = 1/2 arc KL = 1/2(76°) = 38°

which graph shows the solution to the system of equations?y =-2x+1 and y =-3/2

Answers

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)

Answers

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]

Simon's salary has increased by 6% p.a. over the past three years. it is now $35730.40 p.a.
a) what did he earn per year three years ago
b) what is his gross monthly salary at the present rate
c) His deductions each month amount to 22.5% of his gross salary. what is his net pay per month?​

Answers

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.

What is a word problem?

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.

The behavior of the function represented by the given graph: A) The graph is decreasing for all values of x.

What is behavior of function?

As part of exploring how functions change, we can identify intervals over which the function is changing in specific ways. We say that a function is increasing on an interval if the function values increase as the input values increase within that interval. Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval.

In the given graph, the value of y decreases as x increases. Therefore, the given graph represents a decreasing function.

Answers

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

What are complementary angles?

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.

y=6x

Answers

Answer: x-3y=3x

8y=6x8

y=6x

Step-by-step explanation:

Meaning of linear equationA linear equation is a equation that goes at a constant pace and won't change overtime, so functions like x squared and functions that multiply x and y together doesn't go at a constant pace, there not linear equations, but functions like y=mx, M representing any constant, that is a linear equation, therefore    x-3y=3x

8y=6x8

y=6x

Are the answers to your Question,

The equations that represent linear functions are x − 3y = 3x and y = 6x , so options D and E are correct.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line. Functions like y = mx, where m can be any constant, are considered linear equations.

The given equations,

y = −x² + 4y, y = 5 − x²y, 8y = 6x⁸y  on solving get a degree more than 1 then the equation is a linear function, only

x − 3y = 3x

3y = -2x and y = 6x have degree one, so they are linear
