Answer:

The man got a 8% raise.

Step-by-step explanation:

Percentage change        = [Increase or decrease in value / Original Value]*100

Increase in hourly wage = [tex]13.5-12.5[/tex]

                                         =[tex]1[/tex]

Percentage raise             = [Increase in hourly wage / Initial hourly wage]*100

                                         =[tex]\frac{1}{12.5} *100[/tex]

                                         = [tex]8[/tex]%

The man got a 8% raise.

The man's hourly wage increased from $12.50 to $13.50 which, following the formula for calculating percentage change, indicates that he received an 8 percent raise in his hourly wage.

Given that the man's hourly wage increased from $12.50 to $13.50, we can use the formula for calculating the percentage change to find out what percent raise he got.

The formula for calculating the percentage change is as follows:

[(change in quantity)/(original quantity)] × 100

In this case, the change in quantity (the man's wage increase) is $1.00 (13.50 - 12.50), and the original quantity (the man's original wage) is $12.50.

Plugging these values into the formula, we get:

[1.00/12.50] × 100

This calculates to an 8 percent wage increase. Therefore, the man got an 8 percent raise in his hourly wage.

Answer:

24 ounces.

Step-by-step explanation:

Given that the ratio of blue paint to yellow paint in a green paint mixture is 2:3.

Actual ounces used for blue paint = 16

By ratio and proportion property we have

2:3 = 16:x where x is the actual ounces of yellow paint used.

Simplify using ratio rules

if a:b = c:d then ad = bc

We get

2x=3(16) = 48

Divide by 2

x = 24

Hence 24 ounces of yellow paint to be used.

Step-by-step explanation:

The queen might've asked the king to measure the rug to demonstrate humility, responsibility, highlight practical skills, or grasp the concept of measurement. Without specific context, however, it's hard to pinpoint an exact reason.

Without specific context, it's difficult to provide an exact reason for the queen asking the king to measure a rug. However, in general, English literature often showcases rulers partaking in ordinary tasks as a means of demonstrating humility, responsibility, or attention to detail. For instance, the queen might have wanted the king to measure the rug in order to prove that he can attend to ordinary matters as well as royal duties, or perhaps to prove himself practical and not merely ceremonial. It could also be a ploy to make the king grasp the concept of measurement, size or area, by doing the task himself.

Answer:

As mention in the explanation steps.

Step-by-step explanation:

The following expression or phrase to each box are helpful to complete the proof.

(1). We say that ∠ACB and ∠BCD are supplementary, from linear pair of postulate.

(2). ∠ACB + ∠BCD =180°, because ∠ACB and ∠BCD are supplementary (from the difinition of supplementary angles).

(3). ∠ACB +45° = 180° because ∠BCD =45°(substitute).

(4).Subtraction properties of equality ( because we subtract 45 degree from both sides of the previous equation).

(5). ∠ABC is obtuse, because m∠ABC grater than 90°.

(6). From the definition of obtuse triangle (ΔACB is an obtuse triangle because ∠ACB =135 degree which is grater than 90 degree).

Step-by-step explanation:

Given that there are 5 colour marbles in a large bag.

The colours are red, orange, yellow, blue and green.

Also given that there are equal amounts of each colour

Let n be the no of marbles of each colour.

Then total no of marbles = 5(n) = 5n

No of red,blue and yellow marbles = n+n+n = 3n

Prob of drawing a red or blue or yellow = P(red)+P(blue)+P(yellow)

= [tex]\frac{n}{5n} +\frac{n}{5n} +\frac{n}{5n}  = \frac{3n}{5n}[/tex]

f(x) = 2x + 1

f(3) = 2*3 + 1 = 7

B

g(x) = x^2

g(7) = 7^2

g(7)= 49

C

f(g(x)) = 2(g(x) + 1

f(g(x)) = 2 x^2 + 1

f(g(3) = 2* 3^2 + 1

f(g(3) = 19

D

g(f(x)) = (f(x))^2

g(f(x)) = (2x + 1)^2

g(f(3)) = (2*3 + 1)^2 = (6 + 1)^2 = 49

E

f(g(x)) = 2*g(x) + 1

f(g(x)) = 2*x^2 + 1

f(g(3)) = 2*3^2 + 1

f(g(3)) = 2 * 9 + 1

f(g(3)) = 18 + 1

f(g(3) = 19

F

f(g(x)) = 2(g(x)) + 1

f(g(x)) = 2*x^2 + 1  

So, the product of (9x - 2)(3x - 8) in standard form is: [tex]27x^2 - 78x + 16[/tex]

To multiply the expressions (9x - 2) and (3x - 8)

Step 1: Use the distributive property

(9x - 2)(3x - 8) = 9x * (3x) + 9x * (-8)

(9x - 2)(3x - 8) = -2 * (3x) - 2 * (-8)

So , perform the multiplications:

Multiply the terms:

[tex]9x * 3x = 27x^2[/tex]

9x * (-8) = -72x

-2 * 3x = -6x

-2 * (-8) = 16

Combine like terms:

[tex]27x^2 - 72x - 6x + 16[/tex]

Simplify further by combining like terms:

27x^2 - 78x + 16

So, the product of (9x - 2)(3x - 8) in standard form is: [tex]27x^2 - 78x + 16[/tex]

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

x + 3 = 4 is an equation.

3x + 4x = 4 is an equation.

We have,

3x² + 13x = 10

This can be written as:

3x² + 13x - 10 = 0

Using the Middle term factorization.

3x² + (10 + 3)x - 10 = 0

3x² + 10x + 3x - 10 = 0

This is not possible so,

Using determinant.

3x² + 13x - 10 = 0

a = 3, b = 13 and c = -10

Now,

Determinant is given as:

D = -b ±√(b² - 4ac) / 2a

D = -b + √(b² - 4ac) / 2a

D = [-13 + √(169 + 120)] / 6

D = (-13 + √17) / 6 _____(1)

D = -b - √(b² - 4ac) / 2a

-3.

Hope this helped.

Answer:

x = -3

Step-by-step explanation:

Solving for value of x

−x + (−3) = x + 3              

-x -3 = x + 3                     [subtract x from both side]

-x -3 -x = x + 3 -x

-2x -3 = 3                       [add 3 to both side]

-2x -3 + 3 = 3 + 3

-2x = 6                          [divide both side by -2]

Step-by-step explanation:

Solve each inequality and check which inequality has -12 as a solution

a. [tex]x+6<-8[/tex]

Subtract 6 from both sides

[tex]x<-14[/tex]

b. [tex]x+4>-6[/tex]

Subtract 4 from both sides of the inequality to get x alone

[tex]x>-10[/tex]

c.[tex]x-3>-0[/tex]

Add 3 on both sides

x>3

d. [tex]x+5<-4[/tex]

Subtract 5 from both sides

x<-9

-12 lies below -9. So x<-9 has -12 in its solution

Starting with 113+ (2x+5)=180, combine like terms and to get 118+2x=180.  Subtract 180-118, which gives you 62.  Then you have 2x=62.  Divide both sides by 2 to get a final answer of x=31.

Hey there!!

Given :

... 113 + ( 2x + 5 ) = 180

Subtract 113 on both sides

... 2x + 5 = 180 - 113

... 2x + 5 = 67

Subtract 5 on both sides

... 2x = 62

Divide by 2 on both sides

... x = 31

The value of x is 31.

Answer: x = -1, -3, 7 + √62, 7 - √62

Step-by-step explanation:

q                                    p

x⁴ - 10x³ - 66x² - 94x - 39

[tex]\frac{p}{q}[/tex] = +/- [tex]\frac{1*3*13*39}{1}[/tex]

possible rational factors: 1, -1, 3, -3, 13, -13, 39, -39

Use synthetic division or long division to see which factor will leave a remainder of 0.

try x + 1 = 0  ⇒   x = -1

-1   |  1     -10     -66     -94     -39

    |  ↓     -1        11        55      39

       1     -11      -55     -39       0

(x + 1)(x³ - 11x² - 55x - 39)        

next, try x + 3 = 0  ⇒   x = -3   for the new polynomial

-3   |  1     -11     -55     -39

     |  ↓     -3       42     39

        1     -14      -13       0  

(x + 1)(x + 3)(x² - 14x - 13)

Lastly: find the zeros by setting each factor equal to zero and solve.

x + 1 = 0  ⇒  x = -1

x + 3 = 0   ⇒ x = -3

x² - 14x - 13 = 0

[tex]x = \frac{-(b) +/- \sqrt{(b)^{2} -4(a)(c)}}{2(a)}[/tex]

We are given a figure where M, N , O and P points are given.

We need to explain if points O, N, and P collinear or not.

Note: All co-linear points are in a straight line.

From the figure, we can see that O and N points are in a straight line but point P is aside.

So, the points O, N, and P are not collinear.

Therefore, correct option is "No, the three points are not collinear".

Answer:

If you can maintain this speed you will travel 120 km in 1 hour.

Explanation:

The translated question is, A cheetah can travel 20 kilometers in 10 minutes. If I could maintain this speed for one hour, how many kilometers would you travel?.

 Let us find the speed of cheetah

            Distance traveled =  20 km

            Time taken = 10 minutes = 10/60 = 1/6 hours

            So speed = [tex]\frac{20}{\frac{1}{6} } =120[/tex]km/hr.

 So speed of cheetah = 120 km/hr, which means cheetah will travel 120 km in 1 hour.

If you can maintain this speed you will also travel 120 km in 1 hour.

Apply the vertical line test. Think of a vertical line moving from left to right in the graph. If the graph of the relation intersects the vertical line in more than one point in any position of the vertical line, then the relation is not a function.
